Description
A találmány tárgya kompozíció és eljárás szűrőlemez és síkszerú szűrőanyag előállítására.The present invention relates to a composition and a method for producing a filter plate and a planar filter material.
A találmány szerinti anyag felhasználható folyékony anyagok szűrésére, elsősorban az élelmiszerés gyógyszeriparban.The material of the present invention can be used to filter liquid materials, particularly in the food and pharmaceutical industries.
Síkszerű szűrőanyag előállítására eddig szálas azbesztet alkalmaztak más szálas nyersanyaggá, így tisztított cellulózzal vagy gyapothulladékkal és kemikáliákkal keverve. Az azbeszt mennyisége a szűrőanyagban elérte a 45 tömeg%-ot (például 533 385 számú szovjet szabadalmi leírás, valamint a következő vállalatok termékismertetői: Filtrox-Werke AG., St. Gálién, Svájc [1976], Seitz-Werke, Bad Kreuznach, NSZK [1974-1979], Euzinger-UnionWerke AG., Manheim, NSZK [1974]). Az azbeszt szűrőanyagként történő alkalmazását kiváló szűrőtulajdonságai ellenére is egyre jobban elkerülik, mióta felismerték az azbesztszálak karcinogén hatását.Until now, fibrous asbestos has been used to produce a flat-like filter material into other fibrous raw materials, such as blended with purified cellulose or cotton waste and chemicals. The amount of asbestos in the filter material was up to 45% by weight (e.g., U.S. Patent No. 533,385, and product descriptions of Filtrox-Werke AG., St. Gallen, Switzerland [1976], Seitz-Werke, Bad Kreuznach, Germany). [1974-1979], Euzinger-UnionWerke AG., Manheim, Germany [1974]). Despite its excellent filtering properties, the use of asbestos as a filtering agent has been increasingly avoided since the carcinogenic effect of asbestos fibers has been recognized.
A találmány feladata olyan síkszerű szűrőanyag és szűrőlemez kidolgozása, amely nem tartalmaz egészségkárosító komponenseket, de megőrzi a kiváló szűrőtulajdonságait.SUMMARY OF THE INVENTION It is an object of the present invention to provide a planar filter material and filter plate which does not contain any components that are harmful to health but retains its excellent filter properties.
A találmány szerinti kompozíció a száraz anyagra vonatkoztatva 10-55 tömeg% féltermék, amelyThe composition according to the invention is 10-55% by weight of the dry product, based on the dry matter, which is
2-801% mennyiségben fonható szálas gyapothulladékból, lenből vagy kenderből és 20-98 tömeg% mennyiségben legalább 92 tömeg% α-cellulózt tartalmazó finomított facellulózt és fehérített papírcellulózból áll, valamint 45-89,7 tömeg% kalcinált diatomaföld és 0,3-1,5 tömeg% poliamid-epoxidvagy poliamid-poliamin-epiklórhidrin-bitumen keverékéből áll.It consists of 2-801% by weight of spun cotton waste, flax or hemp and 20-98% by weight of refined wood pulp and bleached paper pulp, containing at least 92% by weight of α-cellulose and 45-89,7% by weight of calcined diatomaceous earth and 0,3-1% 5% by weight of a mixture of polyamide-epoxide or polyamide-polyamine-epichlorohydrin bitumen.
A szűrőlemez és síkszerú szűrőanyag találmány szerinti előállításához a félterméket 22-24 ’SR finomságúra őröljük, hozzáadjuk a diatomaföldet, homogenizáljuk, az abszolút száraz fenti bitumennel adalékoljuk és az így kapott pépet papírgyártó gépeken a szokásos módon feldolgozzuk.For the production of the filter plate and planar filter material according to the present invention, the semi-product is ground to a grain size of 22-24 'SR, the diatomaceous earth is added, homogenized, the absolute dry bitumen added and the resulting pulp processed by paper making machines.
A fenti nyersanyagból előállított szűrőlemez vagy síkszerű szűrőanyag, amely különböző kombinációkban tartalmazza a szálas komponenseket, granulált formában tartalmazza a diatomaföldet, és különböző mennyiségben tartalmazza a szűrőanyagot, széles körben felhasználható és kiváló szűrőhatással rendelkezik. A találmány szerinti termék az iparban durva és finom diszperzióktól kezdve kolloid oldatokig közvetlen szűrésre széles körben felhasználható. A papíriparban általános alkalmazott eljárásokkal előállítható. A kezelt papírmasszát a papírgyártógép szűrőjén formáljuk, nyomással a kívánt vastagságra préseljük, és hengeres és forró légszárítóteremben 94 + 2, -1% szárazanyagtartalomig szárítjuk,The filter plate or plain filter material made from the above raw material, which contains the fibrous components in various combinations, contains the diatomaceous earth in granular form and contains various amounts of the filter material, is widely used and has excellent filtering properties. The product of the present invention can be widely used in industry for direct filtration from coarse and fine dispersions to colloidal solutions. It can be prepared by methods generally used in the paper industry. The treated pulp is molded on a filter of a papermaking machine, pressed to the desired thickness under pressure and dried in a cylindrical and hot air oven to a dry matter content of 94 + 2, -1%,
1. példa °SR gyapothulladékból és finomított, fehérített szulfit lágy facellulóz és fehérített lágy fa-papírcellulóz 2:1 arányú és 22 ’SR értékű keverékéből papír alapanyagot készítünk, ahol a gyapothulladék és a cellulóz keverék arány 3:1. A teljesen száraz szálakhoz 80 tömeg% mennyiségben kalcinált diatomaföldet adunk, a papír alapanyagot hollander2 ben homogenizáljuk, majd 1 tömeg% poliamid-poliamin-epiklórhidrin-bitumennel elegyítjük. Fehér papírvízzel 0,8 tömeg% koncentrációra hígítjuk, és a berendezés hosszanti szűrőjén formáljuk. A végső formát nedves préseléssel alakítjuk ki, majd 94% szárazanyagtartalomig szárítjuk. Vágógépen a kívánt méretre daraboljuk. A kapott síkszerű szűrőanyag tömege 1,300 g/m , vastagsága 3,5 mm, jellemző pórusmérete 2,2 pm.EXAMPLE 1 A paper stock is prepared from 2% SR cotton blend and refined bleached sulphite soft wood pulp and bleached soft wood pulp at a ratio of 2: 1 and 22 'SR, wherein the ratio of cotton waste to cellulose blend is 3: 1. 80% by weight of calcined diatomaceous earth is added to the completely dry fibers, the paper stock is homogenized in hollander 2 and then mixed with 1% by weight of polyamide-polyamine-epichlorohydrin bitumen. It is diluted with white paper water to a concentration of 0.8% by weight and molded on a longitudinal filter of the apparatus. The final mold is formed by wet pressing and then dried to a dry solids content of 94%. Cut it to the desired size on a cutting machine. The resulting flat filter material had a weight of 1,300 g / m, a thickness of 3.5 mm and a typical pore size of 2.2 µm.
2. példaExample 2
Len és kender szálakból előállított félterméket rostokra bontunk és hollanderben 20 ’SR értékre állítjuk. Finomított szulfit hosszúszálas papírcellulóz 3:1:1 arányú keverékét adjuk hozzá, és a teljes keveréket 24 °SR értékre állítjuk, majd a teljesen száraz termékre vonatkoztatva 0,8 tömeg% poliamid-epoxid-bitument adunk hozzá, alaposan elkeverjük, 65 tömeg% kalcinált diatomaföldet adunk hozzá és homogenizáljuk. A kapott papír alapanyagot papírvízzel 0,4 tömeg% koncentrációra hígítjuk és a berendezés kerek szűrőjén formáljuk. A kapott szalagot préseljük és forró levegős csatornán 95% szárazanyagtartalomig szárítjuk. A szárítólemezekről eltávolítva a kívánt méretre daraboljuk. A kapott szűrőlemez tömege 1,150 g/m1 2, vastagsága 3,5 mm, jellemző pórusmérete 4,5 pm.The semi-finished product obtained from flax and hemp fibers is broken down into fibers and adjusted to 20 'SR in a hollander. A 3: 1: 1 mixture of refined sulfite long-fiber paper pulp is added and the whole is adjusted to 24 ° SR and then 0.8% by weight of polyamide-epoxide bitumen based on the completely dry product is mixed, 65% by weight calcined. diatomaceous earth is added and homogenized. The resulting paper stock is diluted with paper water to a concentration of 0.4% by weight and molded on a round filter of the apparatus. The resulting strip is squeezed and dried in a hot air channel to a dry matter content of 95%. Remove from the drying plates and cut to the desired size. The resulting filter plate weighs 1.150 g / m 2 , has a thickness of 3.5 mm and has a typical pore size of 4.5 µm.
