Polypropylene filter plate compared with traditional rubber filter plate:
Filter plate and filter cloth constitute the core working part of the filter press, it is too much to say that the heart, because as long as it appears a little problem will lead to the equipment can not work normally. The selection of press cloth in the "how to choose different forms of filter press cloth" article has a detailed introduction, not here to say more, this article is mainly needle polypropylene filter plate compared with the traditional rubber filter plate to do a contrast.
Compared with rubber filter plate, polypropylene filter plate has the following advantages:
1. Excellent chemical stability
Because the traditional rubber filter plate is made of rubber. And rubber and its products in the process of processing, storage and use, due to the comprehensive effect of internal and external factors and easy to cause the gradual deterioration of rubber physical and chemical properties and mechanical properties, and finally the loss of use value, namely rubber aging. Generally speaking, the filter material contains a certain acid alkaline and temperature, which will aggravate the aging of the rubber filter plate. In contrast, polypropylene filter plate quality is very stable, so that the service life of at least 50%.
2. Outstanding service life
Rubber filter plate, because the rubber under the action of external force, it is easy to appear aging. And polypropylene filter plate, due to the stability of polypropylene filter plate and our unique thermal bonding technology, so that our diaphragm filter plate greatly improves the service life, can be used more than 10000 times.
3. Excellent drainage
My company's polypropylene filter plate in the overall design compared with the ordinary rubber filter plate has a qualitative improvement. This technology is developed by our company's technical staff for many years, using unique convex point design. Filter plate convex point layout is reasonable, good water filtration, smooth drainage. In addition, the hydrophobicity of the polypropylene filter plate ensures that the drainage efficiency in the filtration process is increased by 45%.
4. Excellent filtration efficiency
Our technology compared with the traditional rubber filter plate, not only in the material and filter can have outstanding performance, in the press pressure has also been greatly improved. Our polypropylene diaphragm filter plate press pressure can reach 1.6MPa, far better than rubber filter plate. This can ensure that the cake moisture content is low, to a large extent for the subsequent treatment brings convenience.
5. Superior security
The polypropylene filter plate produced by our company adopts unique thermal bonding technology to integrate the whole filter plate and make it seamless. Compared with the traditional rubber filter plate, can greatly avoid the generation of differential pressure, to ensure the safety of use.
6. Other features
Compared with the rubber filter plate, because the polypropylene filter plate is made of polypropylene material, it can effectively reduce the outward heat radiation and save energy, and the filter plate weight is light, so that the filtration parts handling operation becomes easier, the weight of the whole equipment is reduced, greatly reduce the artificial labor intensity.
