Polyester plastic cloth manufacturers explain the material and performance characteristics
The commonly used filter cloth in the filter filter mainly includes polyester filter cloth, aceston pill filter cloth, nylon filter cloth, and Vilo filter cloth. The material determines the performance characteristics of the filter cloth. Next, I will introduce the characteristics of these commonly used filter cloth materials. Essence
1. Material performance of polyester short fibrous filter cloth: acid resistance, weak alkali, abrasion resistance, corrosion resistance, good response, poor conductive performance. The temperature resistance of polyester fiber is generally 130-150 ° C. In addition to the advantages of ordinary felt filter cloth, the wear resistance is also very good. Because it has a high cost performance, it has become a variety with a large amount of foundation filter materials. Essence Polyester short -fiber filter cloth raw materials are short and hair structure. The fabrics are densely woven, and the granules are well -retained, but the peeling properties are poor and the breathability is poor. Strong wear resistance, water leakage is not as good as polyester fiber filter cloth. Uses: pharmaceutical, sugar, food, chemical, metallurgy, industrial filter machine, centrifuge, etc. 2. The surface of polyester long fibrous filter cloth is smooth and abrasion resistant. After passing the spoop, the strength is better than that, so the fabric has good air permeability, fast water leakage, and convenient cleaning. Uses: pharmaceutical, food, chemical, metallurgy, industrial filter, centrifugal filter cloth, etc.
3. Nylon filtering cloth nylon has high fiber power, with a strength of 4-5.3cndtex. The elongation rate is 18%-45%. The elastic response rate is above 90%when the 10%extension is extended. The nylon force is stronger in the fiber. According to the determination, the abrasion resistance of the nylon fiber is 10 times that of cotton fiber, 50 times the adhesive, and the abrasion resistance is better than a variety of fibers. Nylon fiber is resistant to strong alkali and weak acid. After 16 hours of treatment with NaOH (10%) at 95 ° C, the strength loss can be ignored, but the nylon is not light -resistant and it is easy to change color and brittle. Therefore, the nylon fabric should not be exposed to sunlight for a long time. Uses: rubber, ceramics, pharmaceuticals, food, metallurgy, etc.
4. Category of Pleel Patellar Filter: Pleel Pleel Pleel Pleel Pleel Fiber Filter; Polycerine Film Filter Filter. Filtering performance: short fiber, short fiber, short fiber, spinning gauze hair; long fiber fiber, long fiber, smooth gauze, so the industrial cloth, cloth surface hair, powder filtration and pressure caused by the short fiber woven patella woven The filtration effect is better than long fiber. The industrial cloth caused by pallon long fiber woven has smooth cloth surface and good breathability. The main representatives of the Pleropal Filter Filter Series include medium thin and thick types.
5. Weilun filter cloth. Veon's chemical name is polyvinyl alcohol. Its force is lower than polyester, with a strength of only 3.52-5.72cndtex. The break is 12%-25%. Poor elasticity, poor fabrics, good abrasion resistance, and 1-2 times durability than cotton. But one of the great advantages is that it can withstand the role of strong alkali, and has good hygroscopicity. It is easy to combine with rubber. It is a good material in the rubber industry. There is a contraction, not acidic. Uses: for the chemicals and rubber industries with strong alkali. The filtration capacity of the above commonly used filter cloth is different. To meet different filtering needs, you must choose the supporting filter cloth reasonably. Of course, in addition to the material of the filter cloth, the performance parameters of the filter cloth are also an important influencing factor in the filter effect, including the elongation of the filter cloth, breathability and thickness. , Deng and filtering process to determine.
