Chong Hing perlite filter aid Description: Perlite is acidic siliceous volcanic glass lava containing water of crystallization, is igneous rock. It particles at high temperature calcination process, rock crystal water evaporation, perlite 15-20 times the original volume ratio of rapid expansion, so rich in closed and open pores formed expanded perlite, and then carefully after grinding and winnowing, GK-110 will form perlite filter aid with special properties. GK-110 white powder perlite filter aid is an inert vitreous amorphous particles, the main component of potassium, sodium and aluminum silicate, no smell, itself does not contain organic matter. Production process, perlite after heat treatment to achieve sterilization and eliminate the effect of organic matter, therefore GK-110 perlite filter aid solubility in inorganic and organic acids in extremely low chemical stability, will not affect the filter colored liquid, smell and taste. Each particle perlite filter aid is very irregular curly sheet with a porosity of 80-90% when the filter cake is formed, each particle has many pores interlinked, so you can quickly filtered, 0.1 micron size and capture particles. "Chong Hing perlite plant" Tel: Peng Gang 13,837,655,996 13,323,765,332 15,537,685,357 East Wong Chong Hing perlite filter aids have compared with traditional aid its use on the following characteristics: 1, can absorb in the filtrate (such as alcohol, high nutritional beverages) of protein polymer, more conducive to improving non-biological stability filtrate; 2, can improve the filtration rate and the amount of filtration; reduce the labor intensity of workers; 3, save 20% -25% usage. Use GK - 110 pearlite filter aid your filter products to achieve "cleaner, faster, better", that more clear filtrate, filtration rate, faster and better quality. Chong Hing perlite filter aids physical and operating characteristics of the product: Item Type Bulk density (g / cm) relative to the flow rate (s / 100ml) permeability (Darcy) suspended solids (%) 102um (150 mesh) sieve residue (%) K (fast) <0.15 <30 10 ~ 2 ≤15 ≤50 Z (medium speed) <0.2 30 ~ 60 2 ~ 0.5 ≤4 ≤7 M (slow) <0.25 60 ~ 80 0.5 ~ 0.1 ≤1 ≤3 Year Xing perlite plant recommend several liquid filtration in the amount of aid: (1) Beer: 0.5-2.0kg / 1000L; (2) pre-treated new wine: 0.5-2.0kg / 1000L; (3) pre- press wine processing: 1.5 - 2.5kg / 1000L; (4) non-pretreated new wines: 2 - 4kg / 1000L; (5) antibiotic broth filter: 10 - 100kg / 1000L; (6) enzyme: 10 -50kg / 1000L; Chong Hing perlite filter aid handling: 1. must maintain the difference (△ P) between the outlet pressure is relatively stable slurry was filtered and the filtrate inlet pressure. Otherwise, it will cause the filter layer off cause filter failure. 2. With the continuous filtration, △ P also will continue to increase. When it is increased to the rated pressure filtration equipment, filter should be terminated. 3. A reasonable grasp precoating reflux time, such as filtrate clarity below standard, the Director may be appropriate for some reflux time. 4. Add phase must always pay attention to add if the pump is working properly. Upon termination of filter aid added, will lead to a sharp rise in P, and eventually leading to shortening and reducing the amount of filtration filtration cycle. 5. improper operation, the filter layer partial loss occurs when the filtrate clarification reduce, if not very serious, you can consider increasing the amount of aid so that the filter layer timely repair and restore normal operation. Chong Hing perlite filter aid action methods and actions: (a) is filtered: pre-metered aid and the right amount of clean water or filtered slurry mixed in the feed bucket suspension, and then the pre-coat. The filtrate meet the requirements to be clarity, we are ready to filter pulp was filtered. This advance, the pre-coating directly from the media (the role of this method is generally applicable to deep bed filtration. Filter bed thickness of 3-80 mm. The actual production, but also continue to conduct cutting of the cake (such as a vacuum drum filter machine ), to obtain a new filter bed, remained relatively stable filtering effect (b) Bulk accumulation filtration and pre-coated filter and add two steps: pre-coating thickness of 2-3 mm and its main role is to protect the filter is not contaminated, and to ensure that transferred add instant filter to obtain a clear filtrate. precoat Bohou and structure is particularly important in the whole filtering process using the filter manufacturers can be liquid properties (viscosity, particle size and content of impurities particulate compressibility, etc.), and the filtrate product requirements, filter machine types and operating processes, etc. choose different types of aid and the best size ratio Chong Hing perlite filter aid procedure is as follows: (1) Pre- coating is formed by bridging aid in precoat filter medium and 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 quantitative stripe drainage and serum (or sterilized water) in proportion dubbed 5-10% in pre-coated pot (mass ratio) was suspended slurry circulation through the circulation pump to form a good stable on the filter media precoat. precoat filter 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, complete with different types of aid 2-3 times a 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 After the completion of the pre-coat, to be filtered into the filter pulp machine, you need to add into the slurry with 0.1 to 2.0% by weight of the filter aid. filtration process aid and foreign particle filter pulp in the form of floating county porous cake to keep Economic filtration rate. The addition amount depends on the number and amount of particulate impurities compressibility, compressibility large impurities, a corresponding increase in the amount of filter aid added. for filter press, the ideal amount of pressure to the filter should be When the rated pressure filter cake formation substantially fill the machine allows space to accommodate residues, thereby completing a filtration cycle, the filter unit into the cleaning phase (3) directly filter: Adds process, together with aid and filter pulp into the filter machine. filter aid and filtered slurry solids accumulate together in the original pre-coating or filter layer formed on the surface of new filter layer, so that the filter can remain relatively stable filtration rate. In this case, the Wu added filter aid agent, the particle size characteristics of the decision only on the various slurry solids filtered, without being affected by the form of filter machine. The company provides a variety of uses zeolite powder, bentonite, lithium-bentonite, sodium bentonite, horticultural perlite, air separation plant with perlite, do washing powder with pearlescent sand, perlite filter aid, perlite insulation boards, building glass beads, perlite Cleaner agent, opening perlite, closed-cell perlite, expanded perlite rock and other non-metallic mineral products, according to customer request processing various indicators perlite products.
