Abstract
The present invention relates to a fluoroplastic article, comprising inner and outer fluoroplastic layers and a metal meshwork, the metal meshwork is arranged between the inner and outer fluoroplastic layers, characterized by that said meshwork can be stretched and compressed in the axial direction.
Description
- The present invention relates to a fluoroplastic article, particularly to a fluoroplastic article with liner made of metal meshwork.
- It has well known that fluoroplastic, particularly polytetrafluoroethylene plastic (briefly to say, F4 or PTFE) is used as liners of steel members such as anticorrosive tubes, towers and vessels. When an article made of F4 is used as liners of a steel member, due to a high difference of thermal coefficient of expansion between the article and the steel member, usually they will be destroyed during using. Thus, it has restricted the wide use of this new material in anticorrosive fields. Therefore, the inventor has proposed a F4 liner with metal web laid in it, such that the excessive expansion of the anticorrosive article made of F4 gets restricted during being heated, so as to increase the life of the F4 liner. But the grids of the metal web in the above solution are invariable square one, that is, the wire of the web is fixedly connected with each other, so the metal web can't be stretched and compressed optionally, as shown in
FIG. 1 . There are two shortcomings existing in the web with this structure. 1) Since the grids of the metal web can't be stretched and compressed, when the fluoroplastic article is placed into a tube for example and is expanded to be flanged at the two ends, the metal web in the fluoroplastic article can't be flanged together with the fluoroplastic layer. Thus, the quality and performance of the fluoroplastic article are deteriorated. 2) In the winding process during producing the fluoroplastic article, the metal web with above structure can merely be laid outside of the fluoroplastic belt, but can't be made into meshwork and placed in the fluoroplastic layers. Because the diameter of the meshwork with this structure is not stretchable and compressible optionally and the meshwork is difficult to abut against the fluoroplastic inner layer closely, when the fluoroplastic belt is winding outside of the inner layer, the web will distort. When the article is sintered at a high temperature, since the F4 belt, metal web and glass belt can't be pressed against each other closely, the inner pressure due to the expansion is insufficient, and the metal web will disorder and displace. Thus, the finished articles will have a low density and there will be small holes in the structure. At the same time, these articles will have a trend to crack and will have a high ratio of defective and waste products. - The problem to be solved of the present invention is to provide a fluoroplastic article with a liner made of metal meshwork. It can overcome above shortcomings arising in prior fluoroplastic articles, whose liners are made of metal web with fixed grids.
- The fluoroplastic article according to the invention is composed of inner and outer fluoroplastic layers and a metal meshwork. The metal meshwork arranged between the inner and outer fluoroplastic layers can be stretched and compressed in the axial direction.
- In order to stretch and compress metal meshwork in the axial direction, the grids of the metal meshwork have variable rhombic shape. They are formed by interweaving metal wires or through welding metal webs with stretchable and compressible rhombic grids.
- The advantage of the invention is set forth in the following. 1) Since the metal meshwork is stretchable and compressible, it can be compressed according to the diameter of the inner layer of the wound fluoroplastic article. As the result of being compressed, the diameter of the meshwork extends to be larger than that of the inner layer of the fluoroplastic article. Then, the inner layer of the fluoroplastic article is sheathed by the compressed meshwork. The latter is stretched and the diameter gets small. In this way, the meshwork abuts against the outside of the inner layer. Next, the fluoroplastic outer layer is wound around the meshwork continuously. During winding, the grids of the metal meshwork vary with the state of winding and forces. Thus, the metal meshwork is arranged between the inner and outer layer of the fluoroplastic article submissively, neatly, normally and uniformly without any disorders and displacements. Thereby, both quality and yield of articles are improved. 2) Since the diameter of the meshwork is variable, when the fluoroplastic article with the metal meshwork is lined in a metal member, the metal meshwork can be flanged together with the fluoroplastic layer. Therefore, both quality and performance of the member are improved. 3) As the force applied to different parts of the meshwork is uniform, the article doesn't deform at a high temperature. 4) Since the product of the diameter and the length of the meshwork is a constant, during producing and using, the meshwork will elongate longitudinally and the diameter will expand in the transverse direction with the rise of temperature. Since the tendency to elongate longitudinally and the tendency to expand transversely are restricted with each other, both the length and the diameter of the meshwork can't change. Thus, the performance of expanding with heat and contracting with cold of the article is in an optimum state. 5) Since the metal meshwork of the article is stretchable, during winding or being sintered at high temperature, the meshwork never displaces and will abut against inner and outer fluoroplastic layers closely. Thus, the problem arising by metal web with invariable grids is dissolved absolutely, and the sintered article has a high density and strength, and a good quality and a high success ratio as well. Meanwhile, the finished article whose surface is smooth also has no blowholes or cracks.
