Abstract

The invention relates to a high temperature and pressure resistant filter plate of a filter press, belonging to the technical field of chemical equipment. To solve the technical problem of incapability of implementation of high temperature resistance and high pressure resistance, the invention provides the high temperature and pressure resistant filter plate of the filter press. The filter plate is prepared by the following raw materials in percentage by weight: 45-55% of polypropylene, 6.0-10% of PP-g-MAH, 15-20% of flexibilizer, 20-25% of talcum powder, 0.1-0.5% of wetting agent and 0.1-0.8% of antioxidant. The filter plate has the advantages of simultaneous implementation of high temperature resistance and high pressure resistance, tensile strength of above 45MPa, impact strength of above 50J / cm, resistance to high temperatures of 100-130 DEG C and filter pressure of above 8 kilograms when being used; meanwhile, the raw materials of the filter plate are easy to obtain, low in cost and rational in proportion and have a synergistic effect among each other.

Description

technical field [0001] The invention relates to a filter plate, in particular to a high temperature and high pressure resistant filter plate for a filter press, which belongs to the technical field of chemical equipment. Background technique [0002] Filter press is a filter equipment widely used in chemical industry, metallurgy, food and medicine and other industries. According to the different filtration methods of the filter press, it can be divided into box filter press, belt filter press, diaphragm filter press and plate and frame filter press. Among them, most of the filter plates used in the filter press are rubber filter plates or plastic filter plates. [0003] More specifically, the filter plate of the existing filter press is mainly made of rubber material or polypropylene plus EPDM composite material. Although the filter plate made of rubber has good toughness, its strength is poor, it is not resistant to temperature, and its corrosion resistance is also poor. ...
