Abstract: This invention discloses a fluoroplastic lining manufacture and application technology, and more particularly to a fluoroplastic composite product and its manufacturing method. The product is composed of fiberglass, perfluorinated ethylene-propylene (FEP) and polytetrafluoroethylene (PTFE), wound sequentially on a stainless steel support mold, and then an alkali-free fiberglass strip is wound around an external surface. The product is pressed and sintered at a high-temperature melting condition to permeate the perfluorinated ethylene-propylene (FEP) into gaps on a surface of the fiberglass, and the semi-finished product is taken out from a furnace, and the alkali-free fiberglass strip is removed, and a finished good is formed or cut into plates after demolding. The invention breaks through the technical bottleneck of producing a polytetrafluoroethylene (PTFE) lining for large equipments, reducing the consumption of a large quantity of electric power and coal as well as lowering the transportation cost.
