Problems solved by technology

Due to the large number and heavy weight of the packing rings, in many places, the pure PTFE porous grids formed by molding and sintering are deformed and damaged due to insufficient strength and cannot support the weight of the packing rings, forcing production to stop, polluting the environment, and seriously affecting normal production

Embodiment Construction

[0013] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the polytetrafluoroethylene porous grid plate in this embodiment is a circular porous plate 5, consisting of several polytetrafluoroethylene square strips 1 of different lengths and several polytetrafluoroethylene round rods of different lengths containing reinforcing ribs 4 2 are interspersed and combined. The side of the polytetrafluoroethylene square bar 1 is provided with several round holes 3, and the outer diameters of the round holes 3 and the round polytetrafluoroethylene rod 2 are matched with each other. In order to improve the supporting strength and uniformity of force, the reinforcing rib 4 is a circular steel bar, and the distances between the circular holes 3 are equal. The quantity and thickness of the polytetrafluoroethylene square strips and the polytetrafluoroethylene round rods are determined according to specific usage occasions. For the board deletion of other shapes, i...

Abstract

The invention relates to a polytetrafluoroethylene porous grid plate and a manufacturing method thereof. The grid plate is formed by combining a plurality of polytetrafluoroethylene square bars and a plurality of polytetrafluoroethylene round bars in an interpenetration way, wherein the lateral surfaces of the polytetrafluoroethylene square bars are provided with a plurality of round holes, and the round holes and the outer diameters of the polytetrafluoroethylene round bars are mutually matched. According to the manufacturing method, grid plates of different shapes can be combined as required; and the manufactured grid plate has the advantages of high strength, simple structure, convenience for manufacturing, short production time, less PTFE (polytetrafluoroethylene) raw material consumption, low manufacturing cost, and the like.

Description

technical field [0001] The invention relates to a grid plate, in particular to a polytetrafluoroethylene porous grid plate, which is suitable for grid plates used in towers and other equipment in petroleum, chemical and oil refining industries. Background technique [0002] In important industrial productions such as modern chemical industry, petrochemical and oil refining, due to the serious corrosion of chemical media, steel-lined polytetrafluoroethylene (PTFE) anti-corrosion towers are widely used, and the towers are thin and tall structures with a diameter of ￠1000. Some are as high as 10-30m. However, the PTFE-lined towers are composed of multiple cylinders with a length of 1-2m connected by flanges, and PTFE porous grids are placed between each section of the cylinders to support the packing rings of different materials above. Due to the large number and heavy weight of the packing rings, in many places, the pure PTFE porous grids formed by molding and sintering are d...
