Problems solved by technology

[0004] 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 PTFE sheet treatment technology existing in the technology is only limited to surface treatment. The surface activation layer is prone to failure when it is affected by strong light or temperature, which greatly reduces the composite strength, thereby causing the lining layer to peel off and bulge, which will not only lead to hazardous chemicals. Leakage, in severe cases, even lead to technical problems such as major safety accidents

Embodiment

[0031] Such as figure 1 As shown, a PTFE composite board composite device of the present invention includes a first drying tunnel 3 and a second drying tunnel 4 arranged side by side. The second drying tunnel 4 is located in parallel above the first drying tunnel 3, and its length is the first 60% of the length of the drying tunnel 3, and the outlet ends of the two are flush. At the entrance of the first drying tunnel 3, a PTFE plate unwinding machine 2 wound with a PTFE plate 1 and a composite film 5 are installed side by side. The composite film unwinding machine 6 in which the composite film 5 is a PFA film, the composite film unwinding machine 6 is on the top, and the PTFE plate unwinding machine 2 is arranged vertically, and the PTFE plate is unrolled at the entrance of the first drying tunnel 3 There is a constant speed conveying mechanism between the machine 2 and the composite film unwinding machine 6. The constant speed conveying mechanism includes a driving roller 71 ...

Abstract

The invention discloses a composite device and method of fluoroplastics, and provides a PTFE composite that can completely change the non-stickiness of fluoroplastics, so that the PTFE sheet has excellent corrosion resistance and can be bonded and composited with other materials. The plate composite device and method solve the technical problems in the prior art that the PTFE plate treatment technology is only limited to surface treatment, the surface activation layer is prone to failure, the lining layer is peeled off, and even causes major safety accidents in severe cases. It includes The first and second drying tunnels are arranged side by side. A PTFE plate unwinder and a composite film unwinder are arranged side by side at the entrance of the first drying tunnel. In the first drying tunnel, a glass fiber unwinding and rolling machine is installed at the entrance of the second drying tunnel, and a calender is installed between the outlet ends of the first and second drying tunnels. The PTFE board and composite film exported from the first drying tunnel are After being overlapped with the glass fiber cloth exported from the second drying tunnel, it is extruded and fused by a calender to form a PTFE composite board, and the PTFE composite board is wound on a winding roller through a cooling mechanism.

Description

technical field [0001] 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 [0002] 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 limited to ...
