Lined plastic equipment

Our company's plastic lining equipment adopts advanced hot spinning technology and imported high-performance raw materials. According to the different usage requirements of users,Choose a reasonable formula and the optimal lining thickness to heat melt the plastic with the steel substrate. Its characteristics are that steel and plastic are integrated, with strong bonding force, synchronous expansion and contraction, and not easy to peel off. The lining layer also has the characteristics of no overlapping joints, no bubbles, no pinholes, high impact resistance, good impermeability, smooth and shiny surface like enamel, low friction coefficient, and not easy to scale. Any structural shape equipment, pipeline, and pipe fittings can be processed. The main plastics currently used are ETFE (F-40) and PO.

1 ETFE(F-40)
Made by 1:1 copolymerization of tetrafluoroethylene and ethylene. ETFE (F-40) fluoroplastic is sourced from DuPont in the United States and Asahi Glass in Japan, and is mainly used for anti-corrosion lining. This material has the corrosion resistance of polytetrafluoroethylene and strong adhesion to metals, overcoming the non adhesion defect of polytetrafluoroethylene to metals. In addition, its average linear expansion coefficient is close to that of carbon steel, making TFE (F-40) an ideal composite material with metals and possessing excellent negative pressure resistance.

II PFA
PFA is a perfluoroalkoxy group, which has higher thermal and mechanical properties compared to PTFE (F4) and ETFE (F-40). Its maximum continuous use temperature can reach 260 ° C, and other usage characteristics are similar.

III PO
PO (Polyolefin Resin) is a homopolymer and copolymer mainly composed of olefins such as ethylene, propylene, and butene, as well as partially modified, blended, reinforced, and composite materials. It is currently one of the most ideal anti-corrosion materials. Through scientific formula and the use of hot melt and rotary one-time molding process for lining plastic processing, it has the characteristics of corrosion resistance, anti-static, non-toxic, negative pressure resistance, and can be used in vacuum parts for a long time. At the same time, local damage to the inner lining anti-corrosion layer can be repaired, and it can withstand various acids, alkalis, salts, and certain organic solvents.

4、 PTFE, also known as polytetrafluoroethylene, has similar properties to PFA.
