Perlite filter aid perlite Xinyang Chong Hing special perlite filter aid

Chong Hing perlite filter aid procedure is as follows: (1) pre-coated form a pre-coat bridging through a filter aid on the filter media. Its role is: to prevent the filter pulp (to be filter liquid) particles clog the filter media; that can be qualified filtrate filtration start; easy to clean filter media. The quantity of aid and serum (or disinfected water) in proportion to the pre-coat tank dubbed stripe in 5-10% (by mass) was suspended slurry circulation through the circulation pump to form a good stable on the filter media Pre-coating. Pre-filter coating thickness of about 2-4MM thick (pre-coated filter aid amount 700-1000G / square meter). Rotary vacuum filter machine requires pre-coating 8-15CM. Visual filtering requirements 2-3 times with different types of aid to complete. Low viscosity liquid (about 1CP) typically pre-coated flow rate of about 40L / square meter, higher viscosity liquid precoating velocity reduced accordingly. (2) add a filter aid precoat is complete, the pulp to be filtered into the filter unit, to be added into the slurry with 0.1 to 2.0% by weight of the filter aid. Filtration process and filter aid pulp County impurity particles floating porous filter cake is formed, in order to maintain economic filtration rate. How many depends on the number of the added amount of particulate impurities and compressibility, compressibility large impurities, a corresponding increase in the amount of filter aid added. For filter press, the ideal amount of filtering should be pressure rated pressure, the filter cake is formed substantially fill machine space allows receiving residues, thereby completing one cycle was filtered, the filter unit into the washing phase. (3) Direct Add Filter: Adds the process, together with aid and filter pulp into the filter unit. Filter aid and the filter pulp solids deposited together or the original precoat filter layer formed on the surface of the new filter layer, so that the filter can be maintained relatively constant filtration rate. At this point, Wu added the aid, its size determines only the various properties of solids in the slurry was filtered, and the filter unit is not affected by the formal. The company provides a variety of uses zeolite powder, bentonite, lithium-bentonite, sodium bentonite, gardening perlite, air separation plant with perlite, do washing powder with pearlescent sand, perlite filter aid, perlite insulation boards, building with glass beads, perlite Cleaner agent, opening perlite, closed-cell perlite, perlite and other non-metallic mineral products, customers can request the production of various indicators of perlite products.
