Supply of perlite filter aid 80-120,100-160,160-200 Head

Perlite is a volcanic formation of dense glass-like rock. Perlite crushed after calcination at a high temperature, volume can be expanded more than 15 times. It is made of aluminum silicate molten product composed of potassium and sodium. The expanded perlite is very light, it's 20% smaller than the proportion of diatomaceous earth filter thus reducing the amount of net layer coated on filter plates. Chemical composition of expanded perlite, similar to rhyolite. Expanded perlite processing with a special device to perlite filter aids. It was about a sheet, a sheet or needle angle rod-like structure, a refractive index of 1.458, diameter 15 ~ 60μm pie compressible body, its space volume can account for 80% to 90%, in other words, this bed consisting of filter, 80% to 90% of air. Therethrough, the liquid can get filtered and those in suspension, even fine solid particles can also be trapped down, so as to achieve a higher filtration rate and clarity, even fine particles of 1 micron or less can also be captured to. Gk-110 perlite filter aid, the company is styling products, is the use of Xinyang City Ladder quality natural perlite ore 900--1100 ℃ high temperature extrusion processing, modification, purification, grading from the white powder . Its molecular structure honeycomb, tasteless, non-toxic, sterile, non-organic, is an inert material, the product has the following characteristics: 1, does not dissolve in the liquid to be filtered; the role of 2, and the filtered liquid does not occur ; 3, in the liquid to be filtered wet and spread good; 4, easily painted skeleton filters filter plate and retained in the spacer; 5, coated with a crack resistance on the filter separator; 6, have sufficient thermal stability high temperature liquid filtration. The product is simple to use, and use the same diatomaceous earth filter aid. The product is filtered fast and large, it can filter material to achieve the best transparency of filter substances without any side effects, applicable to many types of filtration process equipment. The product is light weight, low price, the domestic some representative After the industry uses to prove that the product is ideal filtration process, reliable aid, very significant economic benefits.
