Description

Technical Field

[0001] The utility model relates to the field of chemical industry, in particular to a PTFE filler supporting grid plate. Background Art

[0002] Tetrafluoroethylene is a high-performance plastic material with excellent corrosion resistance, high temperature resistance and non-adhesion. Tetrafluoro filler means that tetrafluoroethylene is used as a filler or additive to improve the properties of the material. Tetrafluoro filler support grid plate is a support grid plate with tetrafluoroethylene filler, which can combine the characteristics of tetrafluoroethylene with the structure of the grid plate. It is suitable for special environments or industrial applications that require materials with special properties.

[0003] Since tetrafluoroethylene has excellent corrosion resistance and chemical resistance, tetrafluoroethylene filler support grid plates can be used as components of chemical equipment in the chemical industry, such as pipeline supports, container covers or internal components of chemical reactors. Since the welding performance of tetrafluoroethylene is relatively poor, it is difficult to use soluble plastic welding methods to make support grid plates. At present, the tetrafluoroethylene filler support plates installed in the lined tetrafluoroethylene tower or other internal anti-corrosion tower equipment are mainly made by drilling tetrafluoroethylene molded plates into porous plates. However, due to the poor welding performance of tetrafluoroethylene, it is not convenient to weld and install it with the tetrafluoroethylene tower, which makes the support grid plates inconvenient to use. Therefore, we propose a tetrafluoroethylene filler support grid plate to solve the above problems. Utility Model Content
