Description: Perlite is acidic siliceous volcanic glass lava containing water of crystallization, is igneous rock. Its calcination process at high temperature particles, rock crystal water and evaporated to 15-20 times the original volume of perlite to rapid expansion ratio, thus forming a closed and open pores rich expanded perlite, and then carefully polished after winnowing, GK-110 will form a special performance of perlite filter aid. GK-110 perlite filter aid is a white powder consisting of particles of inert amorphous vitreous, which is the main component of potassium, sodium and aluminum silicate, no smell, itself does not contain organic matter. The production process, high temperature treatment perlite, to effect sterilization and elimination of the organic matter, so GK-110 Perlite filter aid solubility of the inorganic and organic acids very low chemical stability, which will not affect the filter colored liquid, smell and taste. Perlite filter aid each particle is very irregular curly sheet with a porosity of 80-90% when the filter cake is formed, connected to each particle has many pores, it can rapidly filtered, 0.1 microns in size and can capture particles. Compared with the traditional aid perlite filter aid which has the use of the following characteristics: 1, can absorb the filtrate (such as alcohol, high nutritional drinks) part of the protein polymer, more conducive to improving the stability of the filtrate abiotic sex; 2, can improve the filtration rate and the total filtration; reduce the labor intensity of workers; 3, save 20% -25% usage. Use GK - 110 perlite filter aids, filter products can achieve "cleaner, faster and better", ie more clear filtrate, the filtration rate faster and better quality. Several recommended dosage of liquid filtration aid: (1) Beer :0.5-2 .0kg/1000L; (2) pretreated new wine :0.5-2 .0kg/1000L; (3) pre-treated wine press : 1.5 - 2.5kg/1000L; (4) without pretreatment of the new wine: 2 - 4kg/1000L; (5) antibiotic fermentation broth filter: 10 - 100kg/1000L; (6) enzymes :10-50kg / 1000L ; filtering operation Note: the difference between a filter must be maintained (△ P) between the inlet pressure and the outlet pressure slurry filtrate relatively stable. Otherwise, it will cause the filter layer off cause filter failure. 2 with continuous filtration, △ P will also continue to increase. When it increased to the rated pressure filtration equipment, filters should be terminated. 3. Reasonable grasp reflux time precoating operation, such as the clarity of the filtrate was below standard, the Commissioner may be appropriate for some reflux time. 4 Add stage must always pay attention to whether adding pump is working properly. Upon termination of adding the filter aid will result in a sharp rise in P, resulting in a final filtration to reduce the amount of shortening and filtering cycle. 5 due to improper operation, the filter layer partial loss occurs when the filtrate is clarified to reduce, if not very serious, consider increasing the amount of aid is added to the filter layer timely repair and restore normal operation. Methods and the role of aid operations: (a) is filtered: good pre-measured amount of aid and clean water or filtered slurry mixed into the feed bucket suspension, and then pre-coated. The filtrate clarity to meet the requirements to be after, you can filter for filtering the slurry. This intake, pre-coating directly from the media (the role of this method is generally applicable to the deep filter. Filter bed thickness of 3-80 mm. Actual production, but also continue to be cutting back on the cake (such as vacuum drum filter machine ), to obtain a new filter bed filtering effect remained relatively stable (b) accumulation of the precoat filter and adding filtered stacked in two steps: pre-coating thickness is 2-3 mm and its main role is to protect the filter is not contaminated, and ensure instant filtered into added to obtain a clear filtrate. Bohou with pre-coated structure is particularly important in the whole process of filtration using filter manufacturers can be liquid properties (viscosity, particle size and content of impurities select a different type of particulate filter aid and the best compressibility size etc.), and the filtrate product requirements, and operation of the filter unit type matching process like the following procedures: (a) precoating the filter through a filter aid bridging role of media and its role is to form a pre-coating: prevents filter pulp (pending filter liquid) particles clog the filter media; namely, the filter can be qualified filtrate start; easy to clean the filter media quantitative stripe. filter aid and the supernatant (or disinfected water) 5-10% proportion dubbed (mass ratio) was suspended in slurry in the precoat tank, circulating pump cycle is formed by a good stability in the precoat filter media. filter press Machine pre-coating thickness of about 2-4MM thick (pre-coated filter aid quantity 700-1000G / square meter). rotary vacuum filter requires pre-coated 8-15CM. visual filtering requirements, with different types of aid 2-3 times a complete low-viscosity liquid (about 1CP) precoated typical flow rate of about 40L / m2, the higher viscosity of the liquid flow rate accordingly reduce the precoat (2) After completion of adding the precoat filter aid, to be filtered slurry into the filter machine, you need to add the same into 0.1-2.0% by weight of the slurry aid. filter aid during the formation of porous filter cake slurry with impurity particles floating in the county, in order to maintain economic filtration rate. added amount The number depends on the number of particles and the compressibility of impurities, impurity compression rate, a corresponding increase in the amount of filter aid added. the filter, the amount should preferably be filtered when the filtration pressure reaches the rated pressure, and the resulting Basic cake filled with filter machine allows space to accommodate residues, thus completing a filtration cycle, the filter unit into the washing phase (three) added directly filter: add process, pulp filter aid and aid together with the filter into the filter machine accumulation of solids in the slurry in the original joint or precoat filter layer formed on the surface layer of the new filter, the filter so that the filter can be maintained relatively stable speed at this time, the NG aid added, the particle size is determined only various characteristics of the filter slurry solids, and is not affected by the filter machine formality. factory provides a variety of purposes horticultural perlite, perlite air separation device, do washing powder with pearlescent sand, perlite filter aid, perlite insulation board, construction glass beads, perlite and other products, according to customer requirements processing various indicators of perlite products.
