Definitions
- the invention relates to a method of producing an insulation material, the method comprising fiberizing a wood material or another fiberizable material in the manufacturing process of pulp, performing washing and drying, said insulation material being refiberized later so as to provide it with a larger volume.
- the invention further relates to an organic fibrous material, which contains fibrous material fiberized and washed in the manufacturing process of pulp, the fibrous material being compressed and dried into a solid sheet, band or roll formed from the band.
- the invention relates to a blow insulation method for performing insulation, in which method the insulation material consists of a cellulose-based fibrous insulation which is fiberized, washed and dried already in the manufacturing process of pulp, the method comprising delivering the insulation material in a solid form to the installation site, said solid insulation material being refiberized at the installation site in the blowing step so as to provide it with a larger volume.
- cellulosic pulp wool is used either for wood fibre insulations produced from clean wood fibre pulp, as in the present invention, or for an insulation material produced from paper waste.
- Insulations made of wood fibre pulp produced during the manufacturing of pulp are described in FI 97743 and in FI 951624, which have the same inventors as the present application. These insulations are known under the name of VITAL insulation.
- an insulation may be shaped into a board or it may be blown into the desired point in the form of blow wool.
- Blow wool can be used for insulating base floors, intermediate floors and roofs of buildings.
- the present invention relates particularly to a blow wool insulation, but also to an organic fibrous material itself, which can be used for the desired purposes.
- the invention may also be applied to the production of a planar insulation.
- FI 912537 discloses a method and an insulation material in which a wood fibre insulation material produced by chemithermo-mechanical pulp method (CTMP) is delivered to the construction site in a compact form, e.g. in the form of a sheet or roll, which is fiberized into a fluffy form at the construction site.
- CTMP chemithermo-mechanical pulp method
- This method allows to save on transportation costs.
- the publication also teaches the addition of a protecting agent, as distinct from the normal manufacturing process of pulp, after the cellulosic pulp has been washed so that the protecting agent, such as a bactericide, fire retardant or anti-corrosive, is also added in the final stages of the process, e.g. at the wire or upon drying.
- the protecting agent is added before the washing stage, whereby the primary purpose of the protecting agent is to inhibit the growth of bacteria during the manufacturing process of pulp and not to improve the properties of the end product to be produced from pulp.
- the drawback related to the method and the insulation of this publication is that the adhesive is not added until in the final stages of the insulation method, i.e. at the stage at which the insulation material is refiberized into its fluffy form and when the insulation material is blown into the desired point at the construction site.
- the object of the invention is to provide a new solution which allows to avoid the problems and drawbacks related to the prior art solutions.
- the above-mentioned object is achieved with a method of the invention, which is characterized in that an adhesive is added to an insulation material after the washing step but before the refiberization of the insulation material to be performed later so as to provide the insulation material with a larger volume.
- a fibrous material of the invention is further characterized in that the solid fibrous material also contains an adhesive, which is added to the fibrous material washed in the manufacturing process of pulp.
- a blow insulation method of the invention is characterized in that the insulation material to be refiberized at the installation site is treated with an adhesive before the refiberization, but after the washing step of the production of the insulation material is carried out during the manufacturing process of pulp.
- the invention is based on the idea that an adhesive is added to the material of which the insulation product is made.
- the adhesive may thus be added either to a washed pulp which is still in the manufacturing process of pulp, or to a more compact cellulosic sheet, roll containing cellulosic band, cellulosic web or to another fiberizable cellulosic product produced in the manufacturing process of pulp.
- An advantage of the method and apparatus of the invention is that the insulation material is deep-impregnated with an adhesive, which provides the adhesive with a good resistance to wear and evaporization.
- the purpose of the adhesive is to stiffen the structure of the insulation product by adhering the cellulosic fibres of the insulation to other agents added to the insulation product, such as bonding fibres (e.g. viscose fibres).
- the adhesive also joins cellulosic fibres together.
- the method is also simple since for example in the blow wool application the adhesive no longer needs to be sprayed into the insulation product to be blown, which is the case in the prior art methods.
- the invention can also be applied in such a manner that the refiberization is not performed until at the installation site, whereby the insulation material is delivered to the installation site in a compact form, and not in the form of a fluffy insulation, the transportation of which would require several times more capacity.
- the process in question is a manufacturing process of pulp, where an insulation material or another organic fibrous material to be used for other purposes is produced.
- raw material such as chips-like or sawdust-like wood material or another fibrous material is fed into the process.
- fiberization is performed preferably by a chemical cooking method of pulp at a desired temperature, in desired moisture conditions and with desired chemicals, the fiberization comprising separating lignin from the fibres by dissolution.
- washing in block 5 unnecessary and harmful components are washed off from the pulp.
- chemical pulp is produced by the cooking method of pulp. It is possible to use for example the sulphate method or the sulphite method for this purpose.
- the next step comprises compression and drying which are performed in block 7.
- the material is finally shaped e.g. into a sheet-like form or a band-like form, from which e.g. a roll may be formed.
- the invention does not primarily relate to the details of the manufacturing process of pulp but to the addition of an adhesive to the cellulosic material to be used as an insulating material or as an organic fibrous material.
- an adhesive to the cellulosic material to be used as an insulating material or as an organic fibrous material.
- the details of the manufacturing process of pulp reference is thus made to the prior art, e.g. to the publication Selluloosa- ja paperiteknologia (Cellulose and Paper Technology), by Markku Laatikainen, 1987, Lappeenranta University of Technology.
- the invention primarily relates to a method of producing an insulation material.
- the method comprises fiberizing wood material or another fiberizable material in the manufacturing process of pulp in block 3, washing it in block 5 and drying and compressing it into a solid form in block 7.
- the dried insulation material is finally shaped into a sheet-like form or a band-like form, from which a roll is formed.
- the insulation material, or more precisely compact insulation material having the form of a sheet or a band, for example is refiberized either into a blow insulation according to Figure 4 with an apparatus according to Figures 2 to 3, or into an insulating board of Figure 6 with the apparatus according to Figure 5.
- the insulation product is provided with a larger volume, and thus it becomes fluffy.
- a solid insulation material which is in a compact form is refiberized so as to provide a fluffy insulation product which has a larger volume and comprises separate fibres or fibre bundles.
- the refiberization may take place several days, weeks or even months after the manufacturing process of pulp, for example after the compact insulation material has been delivered in the form of sheets or rolls from the pulp factory to the one who will perform blow insulation or to the producer of insulating boards.
- An essential feature of the invention is that an adhesive is added to the insulation material after the washing step of block 5, but before the refiberization of the insulation material to be performed later so as to provide the insulation material with a larger volume. Addition of the adhesive after the washing ensures that the adhesive content remains adequate. Addition of the adhesive before the refiberization in turn simplifies the blowing of the insulation product into the desired point in the form of blow insulation wool, or alternatively simplifies the production of a planar insulation from the insulation product.
- the adhesive may be added in various steps.
- the adhesive treatment is performed in the final steps of the actual manufacturing process of pulp after the washing step, i.e. after block 3, before the insulation material is provided with its final moisture content upon drying.
- An advantage of this is that the adhesive is absorbed easily into a moist and warm material.
- the adhesive treatment can be performed on the insulation material after the actual manufacturing process of pulp, the insulation material being compressed and in the form of a straight band, a roll formed from the band-like insulation material, a sheet or in another form, which insulation material will be refiberized later on.
- arrows A and B indicate the addition of the adhesive.
- refiberization takes place when a blow insulation is produced from the insulation material.
- blow insulation it is possible to use an apparatus of Figure 2, which comprises a blower 101 and a refiberizer 102.
- the insulation material to be refiberized is in the form of rolls 103, 104 from which band-like insulation material is fed into the inlet opening 105 of the fiberizer 102.
- Reference numerals 106 and 107 indicate the engine of the blower and the engine of the refiberizer.
- the insulation material rolls 102, 103 are arranged on rotation supports 109, 110 of a support 108 in the apparatus.
- blow insulation is implemented in such a manner that the refiberization to be performed later on, before which the adhesive treatment is carried out, takes place after the actual manufacturing process of pulp, the insulation material being already transferred to the installation site in a more compact form or at least to its immediate vicinity, whereby the refiberization takes place at the installation site or in its immediate vicinity when the installation material is blown into the desired point in the form of a blow insulation.
- the refiberization apparatus according to Figure 2 has thus been transferred to the installation site, i.e. construction site, for example in a container or in a trailer and the insulation material has been transferred in the same way, for example, and specifically in a solid form and not in a fluffy form packed into bags, as usual.
- this preferred embodiment has the advantage that the adhesive needs not be handled at the installation site because it has already been added to the insulation material for example in the pulp factory during the manufacturing process of pulp or during the handling of cellulosic sheets or rolls.
- FIG. 5 denotes a refiberizer, which may work on the same principles as the apparatus illustrated in Figures 2 and 3.
- reference numeral 201 denotes a blower through which distributed, i.e. refiberized, cellulosic wool insulation, i.e. wood fibre insulation 202, is fed into a funnel 203. At the bottom of the funnel 203 there is a wire 204 which rotates between rolls 205. Vertical slabs defining the width of the insulating boards are provided on the wire 204 in its longitudinal direction.
- a distributing conveyor 207 rotating at the speed of the wire conveyor 206 is located at the lower portion of the funnel 203 on rolls 208. Pushers 209 of the distributing conveyor 207 are abutted against the surface of the wire 204 in their lower position.
- viscose gauze may also be used as the coating of insulating boards.
- a lower viscose gauze 211 is fed from a roll 212 onto the wire 204.
- vacuum suction may be used, in other words, a cellulosic insulation, or wood fibre insulation, or organic fibrous insulation 202 is sucked with blowers 213 and 214 into a smooth mat on top of the viscose gauze 211.
- the low pressure produced by the blowers 213 and 214 is equalized with suction boxes 215 and 216 located below the wire 204.
- the arrows indicate the direction of flow.
- Flattening means such as a rotary brush 217 flattens the thickness of the insulation layer 218.
- An upper viscose gauze layer 219 may be fed onto the insulation layer 218 from the roll 220 with a wire conveyor 221.
- a wire 222 presses the viscose gauze 219 onto the insulation layer 218.
- the wire 222 is located between rolls 223. Air is circulated with a blower 224 through the insulation layer 218.
- the arrows indicate the flows in a feed box 225 and suction box 226.
- a condenser unit 228 for separating water from the air flow and a heater unit 229 for heating the drying air are arranged in a circulation conduit 227 in the flow direction.
- a continuous insulating board is cut into separate insulating boards having a given length. The completed insulating board 230 is supplied to the rolls 231 for packaging.
- the insulating board 230 is shown in Figure 6.
- the insulating board 230 comprises two wide side planes 331 and 332 and four smaller end planes 333 to 336.
- the insulating board 230 comprises a base material 337 of cellulosic pulp wool, i.e. wood fibre pulp.
- the insulating board 230 may also comprise a bonding agent, i.e. bonding fibres 50, which may be for example bits of short or long viscose fibres.
- the insulating board also contains an adhesive.
- Reference numerals 339 and 341 indicate viscose meshes or other surface layers. In Figure 4 reference numerals 337 and 50 are used for wood fibres and bonding fibres.
- the adhesive in the insulating material is mainly in a crystal form or otherwise dry when the thickness of the insulation is being flattened after the refiberization, and an adhesive is added to the insulation material after the washing step but before the refiberization to be performed later so as to provide the insulation material with a larger volume, and after the thickness of the insulation product has been flattened with the flattening means 217 in Figure 5, the insulation is moisturized in order to activate the adhesive.
- the moisturization can be carried out with block 240, which may be for example a steam generator 240.
- the adhesive is used for joining bonding fibres added to the insulation material, such as viscose fibres, and other bonding fibres with the wood fibres of the insulation.
- the adhesive also joins the wood fibres together.
- bonding fibres or another bonding agent may be added to the refiberized insulation material for example through the inlet opening 120 of the apparatus for spreading blow wool illustrated in Figure 2.
- a bonding agent such as viscose fibres which mix into the wood fibres of the insulation, for example into the refiberizer 200 or blower 201 in Figure 5.
- the adhesive that was added earlier is dry in this step, but it will be moisturized later on.
- the adhesive to be added to the insulation material is a cellulose-based adhesive, such as a cmc adhesive or another cellulose-based adhesive.
- a cellulose-based adhesive such as a cmc adhesive or another cellulose-based adhesive.
- Such an adhesive is particularly suitable for use in a cellulose-based insulation material, which contains wood fibres.
- a protecting agent is also added to the insulation material, and the protecting agent is also added after the washing step but before the refiberization.
- the principle is the same as in the addition of an adhesive to the insulation material. More preferably, the adhesive and the protecting agent are added to the insulation material substantially simultaneously, which simplifies the method.
- the protecting agent contains preferably boron and borax, or at least one of the following substances: ammoniumpolyphosphate, aluminiumhydrate, aluminiumtrichloride, antimonioxide, aluminiumoxide. These chemical substances provide a good protection against fire, mould and bacterial growth.
