Filter Paper


Product Detail


Viscous liquor filter paper is specially used to filter viscous liquid specialty paper. The so-called viscous liquid, the liquid is sticky and thick, which is different from the general liquid, and is different from the non Newtonian fluid (slurry), slow, with a simple method of filtering is very difficult. What is more, the liquid in addition to contain some of the dust, but also contains not completely dissolved colloidal particles. The former is fixed, and the latter is easily deformed. Filter, no pressure flow does not move. Increasing the pressure after the resistance of colloidal particles left on the surface of the filter material is extruded into the internal pore. The filter blocking, reduced filtration efficiency decrease, then increase the pressure will be "dangerous wear filter.

 

Common viscous liquid: 

paint, animal glue, sulfonated mucus, polyacrylonitrile, cellulose acetate etc.. The material itself has a lot of viscosity, and its fine particles, which is about a few microns or even lower. Some particles also have electrical properties, in addition to them so that they do not conduct electricity, is a precision filter must be borne by the task.

过往,常用于黏稠液体过滤的是加压式的板框过滤机。其过滤介质多为棉布、织物,过滤级数(即次数)分为一级、二级、三级。采用三级过滤时使用的过滤介质:第一级3层是纱布、棉垫、纱布。第二级6层是府绸、白布、绒布、纱布、棉垫、纱布;第三级4层是绒布、白布、府绸、府绸。这种过滤方式不仅本钱高、浪费大,滤液的质量也不理想。因此,假如使用黏稠液体过滤纸,就可以避免黏稠液体过滤时那些麻烦事情,以纸代布,轻松地解决这个题目。

In the past, commonly used in viscous liquid filtration is pressurized filter type. The filter media are mostly cotton fabric, fabric, filter series (that is, the number of times) is divided into one, two, three. Filter media using three filter: the first 3 layers of gauze, cotton pad, gauze. Second the 6 layer is a white cloth, poplin, cloth, gauze, gauze; third stage and 4 layer is cloth, cloth, poplin, poplin. This kind of filtering means not only cost is high, waste is big, the quality of filtrate is not ideal. Therefore, if the use of viscous liquid filter, it can avoid viscous liquid filtering those troubles, the paper Taib easily solve this problem.

沈阳市长城过滤纸板有限公司研发并生产的粘稠液体过滤纸使用的原料采用漂白亚硫酸盐针叶木浆和经过高级处理针叶浆,在工艺上特殊控制好打浆度.适当添加增强剂。经市场验证,过滤粘稠液体效果良好。

Shenyang Great Wall filtration cardboard Co., R & D and production of the viscous liquid filter paper using the raw materials used in the bleaching of softwood sulfite pulp and after advanced treatment of coniferous pulp in the process, special control of beating degree. Adding strengthening agent. Proven by the market, the effect of filtering viscous liquid is good.

当前.过滤技术已经成为质量治理的重要的手段之一。随着高新技术的发展,将需要功能更多、规格齐全、品质优异的特种过滤材料。与此同时,过滤性特种纸的应用范围扩大到航天、航海、基因工程、生命科学等领域,意义远大。

Currently filtering technology has become one of the important means of quality control. With the development of high and new technology, will require more functional, complete specifications, excellent quality of special filter materials. At the same time, the application scope of the filter paper is extended to space, navigation, gene engineering, life sciences and other fields.
