Filter press classification
Divided into box-type filter press, belt filter press, belt-type concentrated dehydration machine is sludge, food filtration equipment commonly used in the early 18th century for chemical consumption, still widely used in chemical, pharmaceutical, Metallurgy, dyes, food, brewing, ceramics and environmental protection industries. Filter press consists of a plurality of filter plates and filter frame composed of filter chamber, and pressure to filter propulsion filter. Filter press for intermittent operation, a frame filter, box filter and vertical filter press 3 categories. Filter plate with stable performance, convenient operation, safe, labor-saving, metal and plastic filter casting casting, high temperature, high pressure, durable.
Filter press in the process of using
As the filter itself is the same size filter, and thus for different filter objects requested by different filtering accuracy, speed, etc., are through the use of different filter press filter cloth, also known as filter bag filter, each piece Filter press plate is a filter cloth wrapped, for different filter objects of acid and alkali requirements, tensile strength, filtration accuracy, filtration speed and other requests, first affirmed the use of filter cloth material, model, and then according to the filter plate Size, shape, processing and matching filter bag, set on the filter cloth can be, so that the filter cloth is the heart of the filter, the filter is also true.
Filter cloth include: filter press polyester filter cloth, filter press polypropylene filter cloth, frame filter press nylon filter cloth, frame filter press vinylon cloth.
Frame filter press polyester filter cloth
Divided into polyester filament cloth, polyester staple fiber cloth.
Polyester staple fiber cloth material properties: acid and alkali resistance. Wear resistance, corrosion resistance, good recovery, poor conductivity. Polyester fiber heat resistance are generally 130 --- 150 degrees Celsius, the product has the unique advantages of ordinary felt-type filter cloth, and wear resistance is very good, with a high cost and become the largest use of felt filter media kind of. Heat resistance: 120 ℃, elongation at break (%): 20-50, breaking strength (g / d): 438, melting point (℃): 238 · 240, freezing point (℃): 255-260. Weight: 1.38. Filtering properties: Polyester staple fiber cloth raw material structure of short hair, woven fabric dense, good particle retention, but peel, poor ventilation. Strength and abrasion resistance, water leakage is less than polyester filament cloth.
Use: pharmaceutical, sugar, food, chemicals, metallurgy, industrial filter press, centrifuges and so on.
Softening point (° C): 238-240, Condensation point (° C): 255-260. Weight: 1.38. Filtration performance: Polyester filament fiber cloth appearance lubrication, good abrasion resistance, high strength, after twisting twisting, higher strength, better wear resistance, so the fabric breathable performance, fast leakage, easy to clean. Uses: pharmaceutical, food, chemicals, metallurgy, industrial filter press, centrifuge filter cloth.
Nylon filter cloth
Nylon fiber high strength, strength of 4-5.3Cndtex. Elongation of 18% to 45%. Elastic at 10% elongation with the rate of 90% or more. Nylon strong in the strongest in the fiber, according to the determination of nylon fiber wear resistance of 10 times the cotton fiber, viscose 50 times. Wear resistance in the first of a variety of fibers, so together with the rubber pressure is the ideal material for the manufacture of automotive tires. Polyamide fiber alkali resistance, weak acid. The loss of strength after NaoH (10%) treatment at 95 ° C for 16 hours can be negligible, but nylon is not resistant to light and is prone to discoloration and brittleness, so nylon fabrics should not be exposed to sunlight for long periods of time. Nylon 66 can not be used in pharmaceutical, food manufacturers, because it is toxic, harmful to human health.
Uses: rubber, ceramics, pharmaceuticals, food, metallurgy and so on. Product Type: 30l, 407,663,17-2,17-7.
Polypropylene filter cloth
Filter cloth classification: polypropylene staple fiber cloth; polypropylene filament cloth.
Filtration performance: Polypropylene staple fiber, short fiber, spun yarn with wool; polypropylene fiber, fiber length, the composition of the yarn lubrication, so the formation of polypropylene staple fiber industrial fabrics, cloth with hair, powder filtration and pressure Filtration better than long fibers. Polypropylene long fiber woven industrial fabrics, cloth lubrication, breathable performance.
Polypropylene filter cloth series of the main representatives are:
In the book type: 521 522 4212 750A thick type: 750B (series) 750AB
Vinylon cloth
Performance: PVA fiber cloth called the chemical title of polyvinyl alcohol, which is lower than the polyester strength, the intensity is only 3.52-5.72Cndtex. Elongation at break 12% ~ 25%. Poor flexibility, poor adherence to the fabric, good wear resistance, durability 1-2 times more pure cotton. However, one of the biggest advantages is that it can withstand strong alkali and has good hygroscopicity and easy separation from rubber. It is a good material to be used in the rubber industry. Its defect is the low temperature resistance. When the temperature reaches 100 ℃ A contraction, not acid. Use: For more alkaline manufacturers and rubber industry.
