Combining device and method of composite PTFE (polytetrafluoroethylene) plate

Abstract

The invention discloses a fluoroplastic combining device and method and provides a combining device and method of a composite PTFE plate, which are capable of completely changing the non-sticky property of fluoroplastic and endowing the PTFE plate with excellent corrosion resistance and enable the PTFE plate to be spliced and combined with other materials. The technical problems that the PTFE plate treatment technology is only limited to surface treatment, and a lining layer is peeled and bulged and even worse, severe safety accidents are resulted because a surface activation layer easily loses effectiveness are solved. The combining device comprises a first drying tunnel and a second drying tunnel which are arranged side by side, wherein a PTFE plate unwinding machine and a composite film unwinding machine are arranged at the inlet end of the first drying tunnel side by side; the PTFE plate and a composite film are synchronously introduced into the first drying tunnel through a fixed-speed base material conveying mechanism after being superposed; a glass fiber cloth unwinding machine is arranged at the inlet end of the second drying tunnel; a plating press is arranged between the outlet ends of the first drying tunnel and the second drying tunnel; the PTFE plate and the composite film, which go out of the first drying tunnel, and glass fiber cloth going out of the second drying tunnel are superposed and then are extruded and combined through the plating press to form the composite PTFE plate; the composite PTFE plate winds a winding roller through a cooling mechanism.

Description

[0001] technical field [0002] The invention relates to a compound device and method of fluoroplastics, in particular to a PTFE composite plate which can completely change the non-stickiness of fluoroplastics, so that the PTFE plate has superior corrosion resistance and can be bonded and compounded with other materials Composite device and method. Background technique [0003] As a polymer material with excellent performance, PTFE has excellent chemical stability, electrical insulation, extremely low dynamic friction coefficient, non-combustibility, chemical corrosion resistance and high mechanical strength, and is widely used in various industries. Especially the lining of anti-corrosion equipment, but due to the poor wettability of PTFE materials, it cannot be infiltrated by adhesives, which limits its application. For this reason, people have begun to develop processes that can improve their surface properties. The existing PTFE sheet treatment The technology is only li...

AI Technical Summary

Problems solved by technology

[0005] The present invention mainly provides a PTFE composite board composite device and method that can completely change the non-stickiness of fluoroplastics, so that the PTFE board has superior corrosion resistance and can be bonded and composited with other materials. The existing PTFE sheet treatment technology in the technology is only limited to surface treatment. When the surface activation layer is affected by strong light or temperature, it is easy to fail, which greatly reduces the composite strength, so that the lining layer peels off and bulges, which will not only lead to hazardous chemicals. Leakage, in severe cases, even lead to technical problems such as major safety accidents
