Printed and printed by the Central Standard Falcon Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs A7 _______B7 _ V. Description of the invention (1) The present invention and the filter material, filter membrane and gas or liquid containing polyaryl ether for removing ozone from gas and liquid (..Polyarylene ether) is related to the method of contacting the filter material. It is known that there will be a small amount of ozone in the process of electrophotography, photocopying and printing. The equipment used, such as photocopiers or laser printers, continuously emits the generated ozone into the surrounding atmosphere. Ozone is a pollutant in terms of taste. At the same time, even a small concentration can have a harmful effect on health. To remedy this, many methods have been developed to remove ozone from the air stream released by such equipment. In these methods, ozone is either destroyed or combined chemically or physically. It is known that ozone can be destroyed by heating or acting with a metal catalyst (see JP-60 1 9 7 223 and JP — 60 19 115). However, the disadvantages of ozone thermal destruction are energy consumption and the high temperature required to complete the decomposition of ozone. In addition, it is also known that a gas stream flows through a filter to decompose ozone in a catalytic manner (see JP — 58 0 8 1 425). Impregnate the basic material of the filter membrane with one or more metal compounds, metals or alloys such as iron compounds' manganese compounds or nickel compounds, and additionally add compounds or metals including noble metals such as palladium or platinum to In the membrane. These catalysts are very expensive and usually only have a limited service life because the heterogeneous catalysts are quickly deactivated by various catalyst poisons. In addition, a filter membrane containing carrier materials such as alumina or activated carbon is also known. It is infiltrated with ethylenic unsaturated compounds that can interact with ozone on a paper scale. It is applicable to the Chinese National Standard (CNS) A4 specification (2丨 0x297 Gongqing)--ml d ^ t • * I (please read the precautions on the back before filling in this page) -4-Annex A: Amendment Page of Chinese Specification of Patent Application No. 841〇9238 ^ 04887 Amend Republic of China In May, 1985, 8a5.2i 4 was amended and the description of the invention (2) started (see DE 37 28 802). The disadvantage of this compound, such as terpene, is that in many cases it is volatile depending on the carrier material used, so it is taken away in a small form and is lost. Also, only a small part of the filter weight can be used as the active ingredient. In addition, it is known that in a filter membrane composed of fiber flat plates for decomposing ozone, the fibers contain a catalyst for decomposing ozone (see J P_0 3 270 718). The fibers that are porous in the preferred system are composed of polymers with the following functional groups that can react violently with ozone: such as a SH, = S, a 1 ^ only 2, =? ^ 11, _ € 1 ^ And -OH. The ozone decomposition catalyst mentioned is composed of metals like gold, silver, copper, palladium, iron, nickel, cobalt and manganese, or their oxides, and alumina and diatomaceous earth. The fibers required to manufacture the filter membrane are obtained by the traditional spinning method, which distributes the catalyst in the spinning solution and distributes them evenly in the fibers after spinning. The second polymer is added, and the phase separation is initiated together with the first polymer, and the spinning product is subjected to various treatments, so that porous materials containing catalyst particles can be obtained. The resulting fibers are then manufactured by conventional methods to make filter membranes. Polymers deemed appropriate are only mentioned collectively.

Invention description (7) The liquid or gas to be processed must be able to flow through the powder without being disturbed, such as in the form of a fixed bed. If polymers are used as fibers, these fibers are applied as staple fibers, needlefelt, non-woven materials, card slivers or fabrics. Films or film scraps can also be used in appropriate forms. Generally polymers can also be applied with undoped materials. However, it is also possible to add fillers-such as chalk, talc, clay or mica, and / or fibrous reinforcements-such as glass fibers and carbon fibers, whiskers (wh i Sker) and other additives and processing aids such as lubrication Agent, release agent, antioxidant and UV stabilizer. The polymer carrier material can be coated by applying a polymer solution (solvent examples are toluene and chloroform) to the carrier material. Impregnation can saturate the absorbent carrier material. The carrier materials used are usually inorganic substances-such as glass, silicone, aluminum oxide, sand, ceramic compositions, metals and organics-such as plastics. It is also possible to apply metals, especially precious metals and transition metals, or metal oxides, such as transition metal oxides, to the polymer substance. The metal or metal oxide can be applied to the polymer by dipping, and then exists in the form of small metal clusters. The process of the invention can be carried out at any temperature below the softening point of the polymer used. Generally speaking, the temperature used is between 0 and 80 ° C, preferably between 0 and 50 ° C. The removal of ozone is usually quantitative. Among many factors, the reaction time depends on the contact time or flow rate of the gas or liquid to be purified.

Invention description (8) Surface area, membrane device Depending on the geometry and temperature. The contact time of the polyarylene ether with the medium to be purified is generally between 0.001 seconds and 10 minutes, more preferably between 0.01 seconds and 5 minutes, and particularly preferably between 0.5 and 1 minute. However, these times can be shortened or extended. The size of the polymer specific surface hull will have a significant effect on the polymer's membrane function. Generally speaking, the greater the filter function of the polymer, the greater the specific surface area of the polymer. Polymers with a large specific area and porous structure, coupled with a proven micropore (micropore) and macropore (macropore) ratio, will be particularly beneficial to the efficiency of the membrane. The efficiency of the polymer membrane is also affected by the crystallinity and the size of the amorphous part of the polymer, respectively. When the polymer has high amorphous parts, it usually has a good effect on the membrane activity of the polymer. For the preparation of polyarylene ethers with large surface grains, such as powders, fibers, or separators, please refer to the German application file reference number P 44 39 478. 0, titled 'for The description of polymer-based filter media that removes components from gases and liquids is included here as reference material.

The ozone concentration was read using a Horiba (Industrytr. 8, D-61449 Steinbach) A P 0 A 350 E measuring device mainly based on a UV spectrometer. The ozone / oxygen mixture is then diluted to a specific concentration with air or argon. Since ozone is known to decompose slowly in water and in humid gases, dry gas is used for dilution. After dilution, the gas flow is divided into several parts. Let one of them flow through an empty tube, while the other part flows through the corresponding vertical tube filled with filter material. In order to allow it to contain polymers, the bottom of the glass tube is sealed with a porous glass plate (frit). Make the flow rate regular so that each unit of time has an equal volume flowing through the two tubes "Example 1 Each different amount of poly [2,6-dimethyl-p-phenyloxide] purchased from Aldrich ( Tg211 ° C, Tm268 ° C, bulk density 0.47 g / cm3) Filled with a diameter of about 25 mm and printed by the Consumer Cooperative of the Central Central Bureau of Economics of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) In a glass tube sealed with frit at the bottom, a gas stream containing ozone flows through the powder bed.

Description of the invention (10) Example 2 15 g of poly (2,6-dimethylphenyl oxide), commercial product S®Blendex HPP 820, was dissolved in 85 g of N-methylpyrrolidone at 90 ° C (Ν Μ P). Use a spatula to apply part of this solution to a glass plate to form a film with a wet thickness of about 200 microns (both the glass plate and the knife are heated to 70 ° C in advance). The coated wet film was immersed in water at 45 ° C. After 2 minutes, the resulting membrane was separated from the glass plate and placed in water for 24 hours to remove residual solvent. Then, the diaphragm was dried in the air >> The circular part with a diameter of 2 cm was clamped and fixed in a diaphragm test cell, and an air stream containing 100 p p b ozone was passed therethrough. The average residence time in the diaphragm is only 2m s. The air flow through the diaphragm was analyzed for ozone content (using Rhode & Schwarz's ozone meter ML 9810). I found that the ozone concentration is below the detectable lower limit of 1 p p b. Even after 2 hours, the ozone concentration is still below 1 p P b ', which shows that ozone can be completely removed in a residence time of less than 1 microsecond. Example 3 The experiment of Example 2 was repeated, but the polymer was purchased from General Electric (USA) * ®Norry (which is a homogeneous blend of PP 0 and polystyrene) Composition) to replace Blendex. The same results as in Example 1 can be obtained, indicating that ozone can be completely removed during the test period of more than 2 hours and with a residence time of 2 ms.

Example 4 80 g of N-methylpyrrolidone and 20 g of polyphenyl oxide are mixed to produce a product at a temperature exceeding 70 ° C The forming solution remains homogeneous. The solution was filtered, heated at 80 ° C and then transported to the spinning head (80 ° C) of the wet spinning via a spinning line (90 ° C). The spinning head has 100 holes with a diameter of 0 · 2 mm. During spinning, immerse the spinning head in a precipitation water bath at 35 ° C. The precipitation part in the precipitation bath is 75 cm long. After flowing through a series of showers, the fibers are wet and entangled. A variation of this method is the manufacture of fiber-dimensional pulp, which is obtained by direct mechanical crushing after coagulation (in room temperature water). The pulp produced in this way was treated with water for several days and then dried at 50 ° C.

The Blendex H PP 8 20 type polyphenyl oxide powder used has a particle diameter of 0-2 to 0.5 mm and a specific surface area of 1.1 lm2 / g. Place the homogeneous polymer solution in a heated dropping funnel and adjust its temperature to 80 ° C. The solution was then added dropwise to a stirred water bath whose temperature was adjusted between 40 and 80 ° C and used as a precipitation bath. Another option is that it is also possible to use heated nozzle tips to add droplets to the precipitation bath. By properly selecting the drip nozzle, the drip rate and the stirring speed in the precipitation bath may change the shape and size of the bulb.
