Изобретение относитс ,к области изготовлени фильтрующих материалов и может быть использовано дл получени волокш1стых фильтрующих материалов, предназначенных дл очистки жидкостей от взвешенных веществ.The invention relates to the manufacture of filter materials and can be used to obtain filament filter materials for the purification of liquids from suspended solids.
Известен способ получени фильтрующего материала из гидратцелшолозных волокон, пропитаншз1х св зующим веществом 1.A method is known for preparing a filtering material from hydrated celtic fibers, impregnated with binder 1.
Однако фильтрующий материал, полученный таким способом, набухает в жидкост х, в св зи с чем ухудшаютс его эксплуатащгонные показатели и ограничиваетс область применени .However, the filtering material obtained in this way swells in liquids, therefore, its performance and carriage characteristics deteriorate and the field of application is limited.
Наиболее близок к изобретению по технической и достигаемому результату способ получе1ш фильтрующего материала дл очистки жидкостей от взвещен П15х частиц, состо щего из смеси синтетических волокон, высокоусадочных волокон и металлических волокон , включающий их обработку полимерами, в качестве которых используют полиамиды. Полимерное покрытие нанос т разбрызгива1шем полиамидного лака с т. пл. 215° С в видеClosest to the invention in terms of technical and achievable results is a method of obtaining a filtering material for cleaning liquids from particles of 15x consisting of a mixture of synthetic fibers, high-shrinkable fibers and metal fibers, including their treatment with polymers, which use polyamides. The polymer coating is applied with a spray of polyamide lacquer with a m.p. 215 ° C at sight

При использовании такого фильтрующего материала дл очистки жидкостей от взвешенных веществ не наблюдаетс высокой степени очистки, так как он не имеет способности флокулировать на своей поверхности мелкодисперсные взвеси. Кроме того, материал имеет короткий фильтровальный цикл.When using such a filtering material for the purification of liquids from suspended solids, a high degree of purification is not observed, since it does not have the ability to flocculate fine dispersed suspensions on its surface. In addition, the material has a short filter cycle.
Цедь изобретени - получение фильтрующего материала, обладающего флокулнрующей способностью дл повышени степени очистки жидкостей.The goal of the invention is to obtain a filtering material having a flocculating ability to increase the degree of purification of liquids.
Поставленна цель достигаетс описываемым способом получени фильтрующего материала, включаюншм обработку синтетических. волокнистых материалов раствором, содержащим 5-20% водорастворимого полизлектролита катионного типа и поливиниловый-спирт, с последующей термообработкой полученного продукта при 100-120° С в течение 20-100 мин. При этом дл обработки берут раствор, содержащий 35-60% водорастворимого по иэлектролита катионного типа и 40-65% полиышилового спирта.The goal is achieved by the described method of obtaining a filtering material, including the processing of synthetic materials. fibrous materials with a solution containing 5-20% of a water-soluble poly-electrolyte of the cationic type and polyvinyl alcohol, followed by heat treatment of the obtained product at 100-120 ° C for 20-100 minutes. At the same time, a solution containing 35-60% of a water-soluble cationic type and electrolyte and 40-65% poly-methyl alcohol is taken for treatment.
