Filter Plate Size 630/800/870/1000/1250 Used For Filter Press Machine

Advantages and disadvantages of various material filter plates:

1: PP polypropylene is currently commonly used, that is, high molecular polypropylene. This material has very good resistance to various acids and bases, including strong acids and hydrofluoric acids. But the operating temperature range is relatively small. Most can only withstand 70 ° materials for a short time. The high temperature filter plate is an organic material with good acid resistance and temperature resistance. The normal temperature resistance can reach about 150°, but the alkali resistance is extremely poor.

2: The diaphragm filter plate has good elasticity, and the moisture content of the filter cake has been below 30%.

3: Rubber filter plate, acid and alkali resistance, high temperature resistance, high sealing performance.

4: Aluminum filter plate, among all metal filter plates, is light, but relatively speaking, it is less resistant to acid.

5: Cast iron filter plate, heavy weight, poor acid resistance and temperature resistance.

6: Stainless steel filter plate has better acid and alkali resistance, but the price is the largest among all filter plates. After all, the material itself is expensive, and the machining time is very long.
