Chong Hing perlite filter aids Description: Perlite is acidic siliceous volcanic glass lava containing water of crystallization, is igneous rock. It particles at high temperature calcination treatment, rock crystal water evaporation, perlite to 15-20 times the original volume ratio of rapid expansion, thus forming a closed and open pores rich expanded perlite, and then carefully after grinding and winnowing, GK-110 will form perlite filter aid with special properties. GK-110 perlite filter aid is a white solid powder inert amorphous vitreous particles, the main component is potassium, sodium and aluminum silicate, no odor, itself does not contain organic matter. Production process, perlite after heat treatment to achieve sterilization and eliminate the effect of organic matter, so GK-110 perlite filter aid solubility in inorganic and organic acids in a very low chemical stability, will not affect the filter colored liquid, smell and taste. Individual particles perlite filter aid is very irregular curly sheet, a porosity of 80-90% when the filter cake is formed, each particle has many pores are communicated so quickly filtered, 0.1 microns in size and can capture particles. Chong Hing perlite filter aids have compared with traditional aid their use on the following characteristics: 1, can absorb the filtrate (such as alcohol, high nutritional beverage category) of the protein polymer, more conducive to improving the non-filtrate biological stability; 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 perlite filter aids, filtration products you can achieve "cleaner, faster and better", that is more clear filtrate, filtration rate, faster and better quality. Chong Hing perlite filter aids physical and operational characteristics of the product: Item Model 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 record Xing perlite plant recommend several liquid filtration aid dosage: (1) Beer: 0.5-2.0kg / 1000L; (2) the pretreated new wine: 0.5-2.0kg / 1000L; (3) pre- press wine processing: 1.5 - 2.5kg / 1000L; (4) a new wine without pretreatment: 2 - 4kg / 1000L; (5) antibiotic broth filter: 10 - 100kg / 1000L; (6) enzymes: 10 -50kg / 1000L; Chong Hing perlite filter aid Precautions: 1. You must keep the difference (△ P) is relatively stable outlet pressure between the inlet pressure filter pulp and filtrate. Otherwise, it will cause the filter layer off cause the filter to fail. 2. With the filter continuously, △ P will continue to grow. When it is increased to the rated pressure filtration equipment, filters should be terminated. 3. A reasonable grasp precoating reflow time, such as filtrate clarity meet the requirements, the Director may be appropriate for some refluxing time. 4. Add phase must always pay attention to whether the pump is working properly added. Upon termination aid added, will lead to a sharp rise in P, and ultimately result in a reduction and shortening the amount of filtration filtration cycle. 5. improper operation, the filter layer partial loss occurs when the filtrate clarify reduce, if not very serious, you can consider increasing the added amount of aid so that the filter layer timely repair and restore normal operation. Chong Hing perlite filter aid action methods and operations: (a) is filtered: The pre-metered good aid and the right amount of clean water or filtered pulp suspension mixed into the feed bucket, and then pre-coated. Filtrate clarity to meet the requirements to be after, you can filter for filtering the slurry. This advance, 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 constantly cutting of the cake (such as vacuum drum filter machine ), to obtain a new filter bed, to maintain a relatively stable filtering effect (b) stacking filtered bulk filtration and precoat and add two steps: a pre-coating thickness is generally 2-3 mm and its main role is to protect the filter not contaminated, and to ensure transferred add instant filtering can get clear filtrate. precoat Bohou and structure is particularly important in the whole process of filtration using filter manufacturers can be fluid properties (viscosity, particle and impurity content particulate compressibility, etc.), and the filtrate product requirements, filter machine types and operating processes such as selection of different types of aid and the best size ratio Chong Hing perlite filter aid procedure is as follows: (1) Pre- Tu formed by bridging aid in pre-coating the filter media and its role is: to prevent the filter pulp (pending filter liquid) particles clog the filter media; that is able to get qualified filtrate filtration start; easy to clean filter media . The quantitative stripe filter aid and the supernatant (or sterilized water) formulated 5-10% in proportion to the precoat tank (mass ratio) was suspended slurry circulation through the circulation pump to form a good stabilization on the filter media The pre-coat. 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, done with different types of filter aid 2-3 times. Low viscosity liquid (about 1CP) precoated typical flow rate of about 40L / square meter, the flow rate of the higher viscosity liquid precoat reduced accordingly. (2) Add a filter aid After the completion of pre-coated 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 floating in the county to form porous cake to keep Economic filtration rate. addition amount depends on the number and amount of particulate impurities of compressibility, compression ratio large impurities, a corresponding increase in the amount of filter aid added. on the filter press, the ideal amount of addition should be a filtration pressure reached rated pressure, fill the filter cake formation basic machine allows space to accommodate residues, thus completing a filtration cycle, the filter unit into the washing phase (3) Direct Add Filter: Adds process, aid went into the filter and filter pulp machine. filter aid and the filter pulp in solids accumulation in common or original precoat filter layer formed on the surface layer of the new filter, so that the filter can be maintained relatively constant filtration rate. In this case, the filter aid added NG agents, its size is only determined by the various characteristics of the filter slurry solids, filter machine without formal impact. The factory 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 board, building glass beads, perlite Cleaner, opening perlite, closed-cell perlite, expanded perlite rock and other non-metallic mineral products, according to customer request processing various indicators perlite products.
