For example, in the past few years, PF and PUF resins, especially glass fiber, have been the mainstream of the technology. These resins are inexpensive and provide a mature glass fiber insulation product having excellent physical properties. 5 This formaldehyde-based resin has been used as a sound-insulating brick, such as a combination of ceiling sheets* 'especially MF, MUF and UF resins, · and PF and MF resins have been used to dip' shell or saturated thin fiber sheets, usually For cellulose, such as paper, the sheet consists of a ply and is cured to form a protective, decorative laminate. Formic acid itself or a composition based on furfural or dispersible formaldehyde has also been used for a long period of time to provide textiles which are free of scalding or wrinkle-free properties. Representatives of this technology are U.S. Patent Nos. 6,827,746; 5,885,303; 4,396,390 and 4,108,598. A rigid but fragile foam made of P F and U F resin to provide water for cutting. These commercially available floral foams are typically formulated with an open cell, matured PF resin, and have the ability to retain a specified amount of moisture. 15 The ability of such furfural-based compositions to provide the necessary properties at a low cost relative to other techniques makes this furfural-based composition popular in the preparation of a variety of commercially and domestically available products. Includes UF, PF, MF, MUF and PUF resins. However, the disadvantage of using formaldehyde-based compositions in such applications is the possibility that the final product will emit formaldehyde. It is known that the gaseous furfural released from this article is partly derived from the unreacted methacrylate in the cured resin binder and partly from the articles under acidic conditions, temperature increase and/or high humidity for a long time. The degradation or decomposition products produced by the components. Therefore, there is a continuing need for a novel method for reducing the furfural emission of a product made of formaldehyde-based or formaldehyde-containing group 6 1377976. SUMMARY OF THE INVENTION According to an embodiment of the present invention, a method for removing furfural emitted from an article selected from the group consisting of a cellulose laminate, a non-scalding textile, a floral foam, and a ceiling sheet is specifically proposed. In a group consisting of a plate and a sound insulating brick, the article is made or treated with a formaldehyde-containing composition, the method comprising isolating the article from a separated furfural-scavenger in a confined space to remove furfural-clearing The agent is in a mass conversion relationship with the article.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT j The present invention relates to a method for reducing the amount of divergence from a product made of or containing a formic acid-divergent composition to the surrounding environment, particularly when the product 5 is shipped or During storage. The present invention is particularly directed to reducing the amount of product selected from the group consisting of cellulosic laminates, non-ironing (anti-wrinkle), ink, and foam panels to the surrounding environment. The present invention is also related to packaging products and, in particular, packagings which tend to reduce the tendency of the article to diverge, the package comprising a methicone having a tendency to reduce the divergence of formic acid or a aldehyde-containing composition such as a formaldehyde-containing resin. According to the present invention, the formic acid scavenger is separately added to a packaged product comprising a formaldehyde-based or furfural-containing composition and thus having a tendency to dilate a formic acid product such as a cellulose laminate (B- Stage laminates and 15 fully cured laminates, wrinkle-resistant fabrics, floral foam or ceiling or sound-insulating bricks are packaged in a manner that separates the formaldehyde from the general environment, such as by sealing in a plastic wrap or The plastic bag is hermetically sealed in a space that separates the surrounding environment. Formaldehyde scavengers are introduced into the thus isolated space containing the product in several ways, such as by being placed in, immersed in, or immersed in a substrate tape placed in the space, or by A gaseous scavenger is injected into the space. The term "furfural-containing composition," or "formaldehyde-based composition" as used herein means a composition or a composition produced by using formaldehyde as a component or component, even if it is not produced using formaldehyde. However, the formaldehyde is dispersed as a degradation product under specific storage or possible use conditions. The formaldehyde-containing composition or the furfural-based composition includes a formaldehyde resin which is generally used as a binder, a binder and a reinforcing agent. The binder and the strengthening agent are made of molar excess formaldehyde and at least one formaldehyde-reactive monomer such as phenol, urea, acetone, melamine and the like. The "methyl resin", typically does not contain, for example, unreacted formaldehyde, And formaldehyde emission occurs during its ripening and without an effective treatment after subsequent aging. Such resins are known to those skilled in the art and need not be described in detail. Such resins are commercially available from resin suppliers such as Georgia-Pacific Chemicals LLC of Atlanta, Georgia, USA. The particular nature of any particular formaldehyde-containing composition and such formaldehyde-containing resin does not form part of the present invention. A furfural-containing resin is widely used in the manufacture of a variety of products including cellulosic laminates and floral foams by reacting molar excess furfural with phenol in the presence of a basic catalyst such as sodium hydroxide. And made. Another common furfural-containing resin is widely used in the manufacture of a variety of products including ceiling or sound-insulating bricks and cellulosic laminates, which are generally based on a molar excess of furfural and melamine in an alkaline catalyst. It is prepared by reacting in the presence of sodium hydroxide. Another common furfural-containing resin is widely used in the manufacture of a variety of products including ceiling or acoustical bricks by reacting molar excess of formaldehyde with urea, usually in the presence of an alkaline catalyst such as sodium hydroxide. And made. As used herein, "curing", "cure (j)" and the like are intended to encompass changes in the structure and/or form of the aqueous binding agent, such as formaldehyde-containing resins, for example, By covalent chemical reaction (crosslinking), ionic interaction or clustering, to improve the adhesion, phase transformation or conversion and hydrogen bonding of the substrate when the resin is dried and heated to a meltable condition. The words "loading", "application", "coating" and "impregnation" are used throughout the specification to describe between a formaldehyde scavenger composition and a substrate for application and retention of a formaldehyde scavenger composition. The nature of the physical relationship. "Load" is a method used to encompass the combination of a formaldehyde scavenger and a substrate. "Coating" and 'coated', for the description of aldehyde scavengers A more appropriate form of the composition when applied to a crucible, sheet or substrate. "impregnating," and "impregnate," are words that are appropriate to describe when the formic acid scavenger is composed. Applied to a permeable or porous membrane, The material or substrate and the description of the composition when it is saturated with the composition. The applicant wants to apply, for example, "application of a formaldehyde scavenger composition to a sheet," "formaldehyde scavenger composition applied to a sheet", " A sheet containing a composition of a formaldehyde scavenger, and the like, to include all such physical forms. The term "curing binder" means aging a furfural-containing resin. "B-stage resin" or " B-stage binder, and the like means a thermosetting resin or binder, such as PF resin, which has been dried but not fully cured. By "reducing the tendency to disperse formaldehyde" and related words means that one consists of formaldehyde Or a product or article made or treated by a furfural-based composition, such as a cellulose laminate, a non-ironing (anti-wrinkle) textile, a phenolic floral foam or a ceiling or a soundproof brick, exhibiting a ratio of formaldehyde Or a product of the formaldehyde-based composition produced or treated but not using the formaldehyde scavenging technique of the method of the invention, which is emitted as a lower amount of formic acid. As used herein, 'aqueous,' means water and a mixture of water In a first aspect, the invention relates to a method of reducing the amount of a product made or treated by a composition comprising or containing a composition of the form A or a leaven-system to the surrounding environment. The invention is particularly concerned with the reduction of cellulose The laminate includes a laminate containing a B-stage resin and a laminate comprising a cured resin, a non-ironing (anti-wrinkle) textile, a foam from the _ flower #, and a ceiling or soundproof brick to the surrounding environment. A method of the present invention is characterized in that a formaldehyde scavenger is inserted into a sealed package containing a formic acid-dispersed product, wherein the scavenger is supplied in a form independent of the product. In the specific embodiment, (4) The agent is combined with a substrate that is independent of the product or article of the A. The substrate is loaded with a formic acid scavenger, such as a material, which is coated on the wire or impregnated into the substrate. Typically, it is applied as an aqueous mixture containing a capping agent, and the 4 substrate is placed in a hermetically sealed package in a mass-to-mass relationship with the product or article. The "hermetic seal" used in the full text of this specification and the scope of the patent application does not require a gas-tight construction and is intended to prevent any discs that are suitable for preventing any discs from being wiped out by the sealed space. Scattered so that the scavenger can be awkward to tap the function. μ is also in the 3 secrets, the method of reducing the product of the tannic acid-dispersing product & formic acid, especially the cellulose laminate including the layer containing the stage resin and the laminate containing the cured resin, the sense of prevention Wrinkle) textiles, creased foams and ceilings or soundproof monuments, all of which are prepared and processed from H compositions, wherein the remote method involves isolating a product in a confined space and independently introducing the agent to the confined space For example, by a separate substrate to which the substrate of the slag scavenger is attached in the viscous state, or by X sealing m-gase, and then maintained in the sealed empty door. Xuan, month remover - enough to reduce the amount of time spent on the disk. The plate remover and product can be introduced into the closed space in any order. In still another aspect, the present invention relates to a method for reducing formic acid-dispersed products or materials, such as a laminate of 3B and a laminate comprising a cured resin. , non-iron (anti-allergic) textiles, (d) flower #bubble and ceiling or soundproof monument, all of which are prepared or treated by a road-system composition, which comprises surrounding or packaging the product 10 or with a film, for example, Packaging the product or the article by a film such as plastic and independently providing the enamel scavenger to such a closed space, in particular a gaseous alpha 2 scavenger or a separate substrate with a substrate with a road scavenger, In order to reduce the amount of formic acid emission by contacting the 'deader' with a quality of the brewed product that is diverged from the product or article. In another example, the present invention relates to a method for reducing the amount of AJ in a wake-up and divergent product, particularly a cellulose laminate comprising a layer comprising B-stage tree 5 and a layer comprising a cured resin. Compound, non-ironing (anti-wrinkle) textiles, various art, transfer and ceiling or soundproofing, etc., all of which are prepared or processed by 曱n composition, which includes placing the product or article in a bag, such as a plastic bag, 2 〇 adding a formaldehyde scavenger to the bag, such as by providing a separate substrate with a substrate containing a age-old scavenger and then sealing the bag, or as before sealing the bag or A gaseous furfural scavenger is then injected into the bag to allow the formic acid scavenger to contact the mass conversion of the formaldehyde diverging from the product or article for a time sufficient to reduce the amount of formaldehyde emitted. 12 1377976 In the case of floral foam, in particular a small but sufficient amount of gaseous formaldehyde scavenger can be injected directly into the foam so that it occupies at least a portion of the space occupied by the open cell body of the foam. These and other aspects of the invention are described in the following specification in conjunction with the specific embodiment. The present invention is not intended to be limited to the specific embodiments disclosed herein. It is intended to be understood by those skilled in the art that the invention may be modified and substituted without departing from the spirit and scope of the invention. A first aspect of the present invention will now be described in conjunction with Figure 1, which illustrates a non-ironing textile article, stored in a plastic package 10 for storage (stocking), shipping and sale in an example of a wrinkle resistant shirt. As shown in Figure 1, a shirt 10 is folded and packaged in a film package, typically a plastic package 20. The folded, crease-resistant shirt is substantially airtightly packaged in a plastic package 20 constituting an interior space 15, and without the present invention, any formaldehyde which is dispersed by the textile article such as the shirt 10 will accumulate in the space 15. In accordance with the present invention, a substrate 30 impregnated with a formaldehyde scavenger is also incorporated into the package 20 and the folded shirt 10. In this embodiment, the substrate 30 can be simply a cellulose sheet, such as cardboard, blotting paper or toilet paper, which is first saturated with a formaldehyde scavenger aqueous solution, such as a solution of a hydrogen sulfite metal salt, such as heavy Sodium sulfite, and then dried. The substrate containing the squeezing remover captures any formaldehyde diffused from the shirt 10 to the interior space 15 during the storage and shipping of the packaged shirt 10 prior to sale. In accordance with the present invention, substrate 30 can be any of a variety of suitable materials that can be used to form a flat, generally elastic layer, film or foil, including, for example, paper, cardboard, plastic (such as Mylar, polyethylene or poly. Gas ethylene), metal (such as Ming) 13 1377976 and other similar materials. The substrate sheet is generally elastic. The sheet may have a single layer structure or may have a multi-layer finish. The sheet may be made of a single material or may be made of a mixture of different substrate materials', e.g., the foregoing. The sheet 30 is sized to allow a sufficient amount of formaldehyde to be removed into the package formed by the film 2 to remove any formic acid that is expected to diverge from the textile article, such as the wrinkle-resistant shirt 10. To reduce or remove the dispersion of formaldehyde from the shirt 10 in the package 20, the sheet 3 is loaded with a formaldehyde scavenger composition. When an impermeable sheet material such as a plastic film is used, the formaldehyde scavenger composition is applied to the surface of the sheet material. For 10 porous sheets, such as blotting paper or toilet paper, the formaldehyde scavenger composition can be applied to the surface or can be impregnated to the thickness of the sheet 30. In either case, the formaldehyde scavenger composition is in a mass conversion relationship with formaldehyde when formaldehyde is dispersed from the shirt 10 to the interior space 15 of the package 20. In a variant of the embodiment of Figure 1, the gaseous formaldehyde scavenger can be inserted/injected into the interior space 15 of the package substantially in a gas-tight manner to replace the insert substrate 30 into the package. A device similar to that described hereinafter with respect to the embodiment of Figure 4 can be used to inject a suitable amount of gaseous furfural scavenger into the interior space 15 of the package 2A. Cellulose sheets coated or impregnated with formaldehyde scavenger or other sheets or films of 20 materials may also be used to remove formaldehyde diffused from the cellulose laminate, the floral foam, and the acoustical ceiling panel. For example, in individual cellulosic laminate sheets or individual ceiling sheets, or in the case of individual floral foam blocks, the contents of the package may be hermetically sealed in a package laminate, sheet or foam. Before the packaging outside the environment, it will carry the expected amount of the net to remove 14 1377976

The structure is similar. The product can be dispensed by placing the product in the bag. In the mode, the paper or film substrate before S can capture the formaldehyde of the package material during use or the inner T and any impurities that are emitted from the laminate, sheet or foam to the inner space of the package during the transfer. For example, it introduces a furfural scavenger into the inner space of a package containing a formic acid-dispersed product such as a cellulose laminate, a ceiling sheet, a floral foam, or a non-ironing product. Referring now to the drawings, Figure 2 shows - an exploded partial cross-sectional view of a variable substrate construction loaded with a dip. In this embodiment, the substrate comprises a container or canister which is filled with a formaldehyde scavenger composition in liquid or solid form. In the specific illustration of Figure 1, the citric acid scavenger is supplied in a solid form, such as powdered sodium bisulfite 5 and a bulky packaging material 6 such as glass, wool or cotton to maintain the powdered scavenger and the feeding container. The airflow channel device is in a spaced relationship, such as It will be described that the container provides a cover 2 having a thread 4 which is complementary to the thread 3 on the container so that when the lid and container are fully engaged, the threads 3 and 4 form a suitable tight seal. 20, the lid and the container are made of a substantially liquid impermeable material, such as aluminum and glass, respectively - the gas flow channel 7 is provided between the furfural scavenger 5 and the interior of the package into which the container is inserted, via the lid wall of the container. Circulation. The gas flow passage 7 provides a removable closure device in the form of a closure patch 8, which may include a commercially available point-fit tape of a suitable size or a metal falling laminate tape applied to the airflow 15 1377976 The surface of the channel 7 to the cover 2 is in close contact with the air flow path and thus prevents the formaldehyde scavenger from prematurely combining the surrounding contaminants before they are inserted into the package containing the formaldehyde-divergent article. When the closure patch 8 is moved by the air flow channel 7 In addition to inserting the container into the interior space of the package containing the methylaldehyde-free product or article, the gas in the space, and in particular the formaldehyde diffused into the space, can flow into the container via the circulation channel, and the scavenger will capture The formic acid is generally irreversibly (e.g., covalent) reacted to remove formaldehyde from the interior space. Figure 3 shows an embodiment of a substrate that is more suitable for the liquid road scavenger composition 10 than the structure of Figure 2. In the embodiment of Figure 3, a perforated dish is used to provide a plurality of gas flow paths to the vessel 50. This container 50 containing a formaldehyde scavenger composition (not shown) is provided - a sealed seal 52 by means of Respective complementary threads 53 and 54. The container is characterized by a porous disc 51 formed on the top surface of the container and providing air flow passage means to the container. Prior to use, the cover 52 is removed by the receptacle 50 and The container is placed in a substantially hermetic sealed space inside the package containing the formaldehyde-dispersible product or article. The gaseous formaldehyde that is dissipated into the inner space of the package will flow into the container through the porous dish 51 and the scavenger will capture the brewing, in general Formaldehyde is removed from the flash space by an irreversible (eg, covalent) reaction. 20 As explained in the following examples, the Applicant has found that the brewing remover is independently placed by the quality conversion relationship between the formaldehyde and the divergent article and that it is not part of the substance tm itself, and in particular is placed with a crucible. Wake up - removes the substrate of the composition, such as a sheet or film that is coated or impregnated or even contains a furfural removal composition, which is placed with a formaldehyde-divergent article in a substantially hermetic sealed package 16 1377976 Implementation—using Ziplock® and Myla® storage bags), a significant reduction in the amount of furfur emanating from material D is achieved. In the practice of the method of the invention 'formaldehyde-dispersed products made or treated with a formaldehyde-containing composition, and in particular cellulose laminates, non-ironing (anti-wrinkle) textiles, 5 floral foams and ceiling or soundproof bricks, One is isolated from the environment. Wrapped in the way of work. The product may be suitably isolated by being packaged in a sealed plastic film, by being placed in a plastic bag or packaged in a phase packaging material. Other packaging products are apparent to those skilled in the art in such a manner that they are substantially airtight and environmentally isolated. The purpose is to package the formaldehyde-divergent product in a 10 inch package. “Substantially airtight” means that the furfural-divergent product is isolated from the environment by a restriction on the way the package enters and exits. The sealed package is placed together with the Ageing Dispersion Product as a separate formaldehyde scavenger, which is easy to In one embodiment, a substrate loaded with a furfural scavenger composition is used. The substrate used in the present invention can be in many forms, such as those described above in relation to Figures 151-3. In a broad aspect, the form of the substrate is not limited. For example, in addition to the pure form of formic acid scavenger, for example, in Figure 2, the introduction of the scavenger is also attempted by using a paper saturated with a formaldehyde scavenger composition. By using a vial or a porous bag comprising a formic acid scavenging composition, such as a solid form of a phthalic acid scavenger composition, which is free to take 2 ounces for isolating the atmosphere, and by using many other configurations In an alternative embodiment, instead of placing a substrate that is considered to be separated and carrying the brewing remover composition in the package, the inner surface of the packaging material itself, ie, the package is exposed to the interior space of the package.

Still other methods of introducing a furfural scavenger into the interior of the package are known to those skilled in the art and the broadest scope thereof, and the present invention is limited by any particular technique. With this configuration, the formaldehyde scavenger composition is placed in a mass-converted relationship with furfural diverged from the product or article, and the two components are isolated from the surrounding environment in a substantially airtight manner. Again, a suitable hermetic configuration is any configuration that would suitably prevent any significant component of the furfural scavenger from being undesirably dissipated in the confined space 10, so that the scavenger can satisfactorily provide its scavenging function. It is not intended to limit the structure of the gas to the confined space to the surrounding air that may be absolutely free of gas exchange. Once in this mass transfer relationship and isolated from the external environment, sufficient contact between the scavenger and the furfur divergence from the product or article can reduce the release of furfural from the product into the environment. 15 A method of preferably treating a formaldehyde-dispersible product, in particular a cellulose laminate, a sound/ceiling panel, a floral foam or a wrinkle-resistant fabric, in accordance with one embodiment of the invention, to reduce the tendency of the product to disperse furfural. The aldehyde scavenger and in particular a gaseous formaldehyde scavenger are introduced into an enclosed space having the product or article. Products can be processed individually or in large quantities. Applicants have discovered that with this technique, 20 can surprisingly achieve a very effective reduction in the propensity of the product to disperse formaldehyde. Indeed, Applicants have found that the use of a gaseous formaldehyde scavenger, in particular, is very effective in reducing the amount of formaldehyde emitted by the product, which requires only a small amount of scavenger to reduce emissions to an acceptable level. Indeed, in the tests completed by the applicant, the formaldehyde emission of an insulating product has been reduced to a level lower than the detection method used to evaluate the aldehyde emission of 1 18 1377976. This embodiment of the invention is not limited to any particular isolation or packaging. The technique of a product or item in a confined space. While available containers, such as - boxes or boxes, are more convenient and less expensive to use a container such as a bag. Alternatively, the product or article may be wrapped in a sheet or film of material to produce - approximately the conformational space of the product. Functionally, such an embodiment of the invention requires the production of a container volume or space in which the product or article is 'packaged or inserted and properly sealed, so added or present in a gaseous scavenger having product space. It can be maintained in a small volume of container volume or space leakage and preferably a loss-free scavenger. Thus, a formaldehyde-dispersible product, such as a cellulose laminate, a sound/ceiling panel, a floral foam or a wrinkle-resistant fabric, can be packaged in a sealed plastic film by placing it in a plastic bag. By suitable packaging by a similar packaging material, or by another similar technique. In this manner, 15 is a quality conversion method that occurs when formaldehyde is emitted and formaldehyde is captured by a scavenger (preferably a blended gaseous scavenger) also present in the bag, which can be optimized and/or promoted. . In a preferred embodiment using a gaseous scavenger, the volume or space of the container used to isolate or package the fibrous product can be comprised of a wide range of materials suitable for use in volume or space during the reaction of the scavenger with free formaldehyde. The gaseous scavenger is maintained from a small volume of the container volume or space and preferably a lossless gaseous scavenger. Materials suitable for sealing and inherently not leaking gaseous scavengers can be used. Although general structural materials such as sheet metal, wood or gypsum board can be used, it is generally convenient to use certain combinations of multilayer constructions such as paper, plastic or foil or its 19 1377976, etc., such as a metal foil-paper laminate. Things. Plastic film packaging materials in the form of sheets or bags, such as polypropylene film, polyethylene film, polyethylene film, or poly δ film (eg, Mylar) are generally suitable. Indeed, an advantage of the present invention is that the basic method of packaging such products for commercial storage and shipping using a plastic package in the form of a sheet or pouch can be readily adapted to the method of the present invention. DETAILED DESCRIPTION OF THE INVENTION A preferred embodiment of the invention is illustrated in conjunction with Figure 4 which illustrates a schematic introduction of a gaseous furfural scavenger to an isolated space to reduce the amount of furfural emanating from the furfural-dispersing product to the space, such as a large amount of wrinkle-resistant fabric. Furthermore, when the present invention is described in this particular embodiment, it will be appreciated by those skilled in the art that the present invention is suitable for use in reducing the tendency of a plurality of products made or treated with a furfural-containing composition to disperse formaldehyde. These include cellulosic laminates, sound/ceiling panels and floral foam. Moreover, the present invention can be practiced using a variety of other techniques for placing the formic acid scavenger and gaseous scavenger into a confined space. 15 Figure 4 is a schematic illustration of a representative device designed to carry out embodiments of the present invention. As shown in Fig. 4, the airtight fabric or the container volume constituting the bag 10 is filled with the tamper-proof fabric article 22. This bag 10 is inserted into an injection nozzle 11 to transport a gaseous scavenger. The bag 10 can be made of one of a variety of plastic films such as polypropylene, polyethylene, polyethylene, polyester, and the like. The nozzle 11 has an opening at one end and a tapered end to facilitate its entry into the confined space. Alternatively, the nozzle 10 can have a series of openings (not shown) along its length to provide a more even distribution of the purge gas throughout the contents of the bag. In still another embodiment, a plurality of nozzles can be used in place of the single nozzle as shown in the schematic to obtain a preferred distribution of scavenger gas throughout the bag 10. These and other changes are within the skill of those skilled in the art. A sealing plate and cymbal combination 23 ensures that the inlet s of the connection between the nozzle u and the bag 1 ’ is either airtight. Testing has shown that this - seal is unnecessary. Other seals formed between the gas injector (e.g., the nozzle (1) and the confined space or the pocket 1" are well known to those skilled in the art. . . . The nozzle 11 is connected to the gas by a gas tube 12. _Container 13. _ - The domain container can be simply - a cylinder of suitable size. Other configurations of supply-like, fixed, * gaseous scavenger to a confined space are apparent to those skilled in the art. Gas filled container 13 The gas inflow and outflow portions may be controlled by H) and (10), and the operations are controlled by controllers 16 and 分别 via control lines (10) and φ, respectively. For safety, the operation of these valves must be interlocked so that when the gas filling container is filled, the sulfur dioxide cannot be inadvertently released through the system. At the inlet side of the gas filling container U is a gas supply pipe connected to a gas supply source 2 such as a gas containing a gas-type scavenger gas cylinder 15 (not shown) such as sulfur dioxide or ammonia. A gas with a plug can also be used to allow gas to flow into the bag. This gas can also be given by a pusher body having a plunger fitting. This and its method of stalking can be used as a sergeant. As will be described below, the cockroach scavenger can be supplied from a mixture of active scavenger gas and an inert carrier or diluent gas. - The variable gas supply line 19 is shown in phantom in Figure 4. The gas supply pipe (4) is made up of unpainted electromagnetic (4) (4), and the material supplied by the scent gas supply pipe a is not supplied with the carrier and the diluted gas. Righteousness. The system operation is very simple. A gaseous scavenger, preferably gaseous sulfur dioxide (or a premix of gaseous sulfur dioxide and a carrier gas such as nitrogen), is supplied from a gas supply source 21, such as a pressurized gas cylinder, via a container 13 The inlet electromagnetic chamber 4 of the pressurizing side is supplied to the gas filling container 13. The gas flowing into the container 13 can be stopped by the preset pressure controller 16 at a pressure that provides a desired amount of injection. At this time, the inlet chamber 14 is closed. The contained gas can then be injected or sprayed into a confined space containing the product, such as bag 10, for treatment with a scavenger. This can be accomplished by placing the nozzle tube η in the container 1G and opening the outlet container valve 15. The nozzle can be inserted into the opening of the bag before the bag is sealed for subsequent storage, transportation and sale. It is also possible to insert the spray after the bag has been prepared for storage, transportation and sale. The wall of the previously sealed bag is pierced or perforated by the nozzle 11. In any event, the release of the gaseous scavenger through the nozzle 11 allows gas to extend into the container 1 through the supply tube 12 and the nozzle u. The outlet valve 15 is then Oh, and heavy This cycle is repeated to inject the subsequent gaseous scavenger into the bag of additional wrinkle-resistant fabric items. When the injection nozzle is removed from the bag 1〇 (provided that there is no additional protection for the nozzle), part of the residual sulfur dioxide gas It is possible for the nozzle u and the tube to escape to the surrounding environment. If this is not expected, then by providing a separate escape gas collection system (not shown) for the nozzle, when the nozzle is treated by the treatment bag Use ι〇 to avoid this result. Alternatively, the apparatus may be adapted or subjected to a separate cycle step in which an intermittent injection of an inert carrier gas (eg, compressed air or nitrogen) is provided after the gaseous scavenger is injected. Short blast) to scrub the supply officer 12 and the residual scavenger such as sulphur dioxide in the nozzle 〇 in the receiving vessel 1 。. For example, the supply line 19 and the electromagnetic switch 2 〇 and the electromagnetic 1377976 can be used to generate the carrier. A sheet of scavenger composition. The essential effect of the substrate whether the substrate or sheet material is coated or impregnated with a formaldehyde scavenger composition such as a sheet of paper. Non-porous or impermeable substrates only accept formaldehyde clear In contrast to the surface coating of the composition of the agent, the substrate of the porous 5 is liable to impregnate at least a portion of the thickness of the sheet depending on the porosity of the substrate and the type properties of the formaldehyde scavenger composition. For example, if a paper or cardboard material is used as the substrate, the formaldehyde scavenger composition can also be added at the wet end of the paper manufacturing process itself. In this manner, the total thickness of the substrate or sheet material can be immersed in the nail. The scavenger composition. 10 The application of the formaldehyde scavenger to the substrate can be achieved via a post-production operation or as part of the sheet production process itself. The invention is also limited by the application or impregnation of the formaldehyde scavenger composition. The manner in which the substrate material is applied. The amount of formic acid scavenging composition applied to the substrate material or impregnated into the substrate material is such that an effective amount of formic acid scavenger composition is provided to capture or remove the divergence of the 15 packets of product. Take a ride. Preferably, the wake-up scavenger composition is applied in an amount of from 7% by weight to about 3% by weight of the substrate material. Typical amounts are from about 1 wt.% to (10) wt%' and more typically from about 2 wt.% to about 50 wt.%. . A main advantage of the present invention is that the application amount of the scavenger is not because the application of the prosthetic scavenger is independent and does not react with the formic acid-containing composition, such as the component of the methyl-based resin binder itself. Poor impact tensile properties or properties of other mature binders. Even if the carbure scavenger is not closely related to the formic acid-containing composition of the product, the Applicant has observed that the scavenger is placed in a quality-to-quality relationship with the product, 27 1377976 on a substrate or in a substrate such as a paper sheet. Or in the paper sheet, a substantial mass conversion between the scavenger and the furfur divergence from the product is provided to reduce the amount of release of the furfural to the environment. Indeed, in some of the experiments conducted, the applicant has observed a decrease in furfural emissions to an undetectable amount. 5 In some instances, the furfural scavenger can be a solid that can be melted to produce a molten liquid, and the present invention is a molten form to which the formaldehyde scavenger is to be applied to the substrate material. In the case of a molten liquid, the scavenger can be sprayed or dropped onto the substrate. In the case where the scavenger is a solid, the scavenger can also be applied as small particles which can be held in the pores of the porous substrate material such as paper 10 (as generally added during the preparation of the paper), or as a separate adhesive. Used to fix to a substrate surface (similar to when preparing sandpaper, the abrasive particles are attached to a support sheet). Preferably, a non-containing furfural binder is used to immobilize the solid particles such as a surface coating on a substrate or sheet material. Particles that pass through a 3 mesh screen (Tyler screen size) but remain on the 100 mesh screen 15 are generally suitable for this use. Other suitable particle sizes for use in accordance with certain embodiments are apparent to those skilled in the art. The granules may be mixed with a binder formulation or sprayed onto a substrate material coated with a wet knot formulation. Alternatively, the scavenger can be supported on an inert support material, such as by coating or absorbing the scavenger, for example, using a water soluble 20 solution, sepiolite, activated carbon, activated carbon fiber, zeolite, activated alumina, vermiculite , diatomaceous earth, perlite granule cellulose fibers, which are then applied to the substrate or attached to the substrate. To facilitate the cleaning of the substrate, it is preferred to place the product and the substrate in a substantially airtight sealed package (as shown below, the Ziplock®-form storage bag uses 28 1377976 Ziplock® bags. In the second contains B_ A Kraft paper having the same laminate size is also placed in the bag of the stage laminated paper. The Kraft paper has a substrate weight of 23 lbs/1000 ft2 and is first saturated with an aqueous sodium bisulfite solution using a size process and then The dried sodium bisulfite was loaded into paper of approximately 34 wt〇/〇e 5 paper. All 4 bags were then sealed. The bagged samples were stored at room temperature for 72 hours. This was stored with or without formaldehyde scavenger. The sample of the Kraft paper laminate was removed from the bag and placed in a Dynaniic Micro Chamber 'DMC, respectively, and the sputum was measured from each of the 10 samples using a constant steady state technique. The emission was collected in an air collector with 20 ml 0_25 N (essentially 1%) of Na〇H and set the air inflow air collector to 1.0 Ι/min. This emission was collected for 3 minutes. Air flow in the DMC. Set to 1 _5 liters / min. This is empty The collector solution was tested for formaldehyde emission using a standard chromic acid method. The DMC is described in U.S. Patent Nos. 5,286,363 and 5,395,494, issued to Georgia-Pacific 15 Chemicals LLC. This removal of formaldehyde from the untreated (control) sample is higher than 7 〇〇ppb.

Four pieces of ceiling panels with 8 inches and 2 inches (160 inches) were cut from commercial panels and two of them were placed in two separate Mylar® bags. The cockroach scavenger-treated paper was prepared by spraying a blotter paper having a size of 12 Å 31 1377976 吋 2) with 5 〇 g of 33 wt ° / 〇 aqueous sodium hydrogen sulfite solution. This saturated paper was then dried in an oven having a temperature of 10 ° C for 2.5 minutes. In a bag, a piece of formaldehyde scavenger saturated paper is placed between a sheet of slab. The two bags were then sealed and used as a control group without a bag containing the treated paper. This bagged sample was stored at room temperature for 72 5 hours. The sample of the laminate stored with or without the remover _ treatment Kraft paper was removed from the bag and placed in a Dynamic Micro Chamber (DMC), respectively, using a constant steady state technique by each The formaldehyde emission was measured in the present. The emission in the chamber was collected in an air collector 10 with 20 ml 0.25 N (essentially 1%) NaOH and set the air inflow air collector to 1.0 Ι/min. And this distribution is collected for 3 minutes. The air flow in the dmC was set to 1.5 liters/min. This air collector solution was tested for formaldehyde emission using a standard chromium acid method. </ RTI> <RTIgt; </ RTI> <RTIgt; 15 After the initial test, the ceiling panels were placed on a rack of a conditioning chamber without any formaldehyde scavenger _ saturated processing paper. After another 1 day and after a total of 38 days of storage (adjustment), the respective sample groups were again tested in the DMC using the same procedure as described above. An air control group was also analyzed in each case to determine the furfural background value in the chamber where the DMC test was performed. The result obtained is 20 in Figure 5. Example 3 Two dark magenta van Heusen dress shirts were purchased from Macy’s, removed from the package and placed in a Ziploc® bag. One was placed in a bag together with the sulphite (Kingjun scavenger) treatment paper, while the other shirt was placed in another bag under 32 without this paper as a control group. A chain scavenger_treated paper was prepared by spraying 54 g of a 33 wt% sodium hydrogen sulfite solution on blotting paper and drying in an oven for 4 minutes. This oven has been heated to 1〇5. (:. Two bagged shirts were stored for 13 days and then removed from the respective bags and tested in DMC to medium respectively. The 曱 chain emission of each sample was measured in DMC (Dynamic Micro Chamber) using the following balancing procedure. The chamber was circulated for 3 minutes and no air flowed into or out of the chamber. After 30 minutes, an air collector was connected to the chamber and the air collector was purged with air at a rate of 1.0 Ι/min for 3 minutes. The air from the device is returned to the DMC. Any waking up from the sample is collected in an air collector using 20 mis 0.25 N NaOH. The Axel emission is done using the standard chromic acid method to test the air collector solution. The formaldehyde emission of the sample was 439 ppb, and the formaldehyde of the sample treated with the sulfite treated paper was 71 ppb.
