The filter press is a universal solid-liquid separation facility. Compared with other solid-liquid separation equipment, the mud cake filtered by the filter press has a higher solid content rate and excellent separation effect, and therefore becomes indispensable for modern industry device of. One of the core parts of the filter press is the filter chamber, which often affects the filtering properties of the filter press. Among them, the filter plate of the filter chamber affects all aspects. The filter plate material of the current filter press can generally be made of wood, glass, plastic, rubber, metal and other materials. The filter plates of different materials have their own characteristics during use. Advantages and disadvantages, so companies need to carefully compare when buying plate filter presses, so as to choose filter press equipment suitable for enterprise production.
At present, many filter plates used in filter presses on the market are improved polypropylene plastic filter plates. Fillers, tougheners, anti-aging agents, antioxidants and other auxiliary materials are added to make them have a good advantage. The plate filter plate of this material has good acid and alkali resistance and high temperature resistance, and can be used in concentrated acid and alkali environments; it can be used in high temperature environments, and the highest temperature can reach 100~120℃; Small weight and long use time
In addition to the filter plate made of polypropylene plastic material, there is also a glass filter plate, which is a glass fiber reinforced plastic form of synthetic resin glued with glass fiber to increase its strength. The filter plate of this material is light in weight and high in strength; it is resistant to acid, alkali, salt and other media corrosion, and has a long use time; the temperature of the filtrate can be about 100 ℃, and it has good heat resistance. But like plastic materials, this material will also experience aging problems after a period of use, but it is slower than plastic materials. In addition, the raw materials of FRP are expensive and the cost is high.
The wood filter plate is generally made of fir material. The filter plate of this material has relatively good sealing performance and is not easy to leak during use. At the same time, compared to the concerns of other materials, the weight is also lighter, which is conducive to transportation and movement. . However, due to the low strength of the wood itself, the filter plate made is easily damaged during use, the use time is relatively short, and it is easily corroded. However, due to the national policy and the shortage of raw materials, such materials are rarely used to make filter press plates.
In general, the most common filter press plate made of polypropylene plastic is currently the most common on the market. Such a filter press has a very high market share. The main reason is that the filter plate of this material has a wide range of applications. And relatively speaking, the service life is longer. Sudong Chemical Reinforced Polypropylene Filter Plate is molded with patented technology, high temperature resistance, the highest temperature can reach 150℃, high pressure resistance, filtering pressure 0.6-2.0MPa, corrosion resistance, PH value 1-14, light weight, non-toxic Odorless, easy to maintain, low investment cost, leading in the same industry.
