Plate and frame is the core part of plate and frame filter press, the quantity, quality and material of plate and frame have a big influence on plate and frame filter press, the material of filter plate of plate and frame filter press usually can be made of wood, glass, plastic, rubber, metal and other materials. Material is the core part of the plate and frame filter press, then, how to choose the material of the plate and frame filter press?
1、Rubber filter plate and frame
Rubber is a better acid and alkali resistant material, but its practicality is limited by the temperature, usually not more than 75, and there are aging conditions.
2、Plastic filter plate
Plate and frame filter press plastic filter plate is an improved version of the polypropylene plastic filter plate, in which add fillers, toughening agents, antioxidants, antioxidants and other auxiliary materials, so that it has good advantages.
3、Glass filter plate
Glass material filter plate is also the FRP form of synthetic resin’s adhesive material, with glass fibre to increase its strength. Such a filter plate has the following advantages: light weight and high strength; acid, alkali, salt and other media corrosion resistance, long service time; filtrate temperature can be around 100, good heat resistance. And its defect is the same as plastic, to aging, but slower than plastic.
4、Wood filter press filter plate
Wood filter plate is usually selected from the wood, so the wood filter plate has good sealing performance, not easy to leak. Manufacturing and processing is more convenient and fast, compared to other materials of concern, the weight is lighter, transport and movement. The defect is that the strength of wood itself is not high, so made of filter plate easy to damage, use time period, easy to be corroded. Plate and frame filter presses, coupled with our tree planting and forest protection system, raw materials are in short supply. Therefore, rarely used filter plates made of this material for filter presses.
The above is a detailed introduction to the plate and frame filter press plate and frame materials, only a full understanding of the plate and frame filter press plate and frame materials, so that you can select a more suitable, firmly believe that this knowledge is very important to many people.
