Audited Supplier Filter plate for plate and frame tye, chamber type and membrane type filter press manufactured by Toper can be divided into:Modified enhanced polypropylene filter plates, glass fiber polypropylene filter plate, rubber membrane filter plates, polypropylene membrane filter plates, cast iron filter plates, stainless steel filter plates, etc.
According to feeding style, it can be classified: Middle feeding, corner feeding and upper middle feeding, etc.
Users can select filter plates in different materials according to their requirements in production process.
2.1 physical properties: PP is non-toxic, tasteless milky white high-crystalline polymers, is currently the most light of all plastic varieties, the water is particularly stable in water 14h water absorption of only 0.01%. Molecular weight of about 8 to 15 million between the good shape. But the shrinkage rate, the original wall products easy to depression, the product surface gloss, easy to color.
2.2 mechanical properties: PP of high crystallinity, structured, and thus has excellent mechanical properties, its strength and hardness, elasticity than high-density PE (HDPE) high. (7 × 10 ^ 7) times. The dry friction coefficient is similar to that of nylon, but it is inferior to nylon in oil lubrication.
2.3 thermal properties: PP has good heat resistance, melting point of 164 ~ 170 ºC, the product can be above 100 ºC temperature sterilization. In the role of external force, 150 ºC is not deformed. Brittle into -35 ºC, below -35 ºC will occur embrittlement, heat resistance than PE.
2.4 chemical stability: PP has good chemical stability, in addition to being concentrated sulfuric acid, concentrated nitric acid erosion, the other various chemical reagents are relatively stable, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons can PP softening And swelling, chemical stability with the increase of crystallinity has also increased. Therefore, PP for the production of chemical pipes and fittings in Russia, anti-corrosion effect is good.
(5) Electrical properties: Polypropylene high-frequency insulation performance, because it is almost non-absorbent, so insulation is not affected by humidity, a higher dielectric constant, and with the temperature rise, can be used to produce heated Electrical insulation products, the breakdown voltage is also high, suitable for electrical accessories. Anti-voltage, arc resistance is good, but the high electrostatic, easy to aging with the copper contacts.
