Coating device and method for teflon tank

Abstract

The invention provides a coating device for a teflon tank. The coating device comprises a curing furnace with a cavity, a trolley for bearing a tank body, and a coating fun for coating with powder. According to a coating method for the teflon tank, the curing furnace brings a coating environment and a curing environment for the tank body at the same time, so that the tank body can be cured after being coated without transferring, the non-cured coating does not contact with the outside environment, the influence of outside adverse factors on curing is prevented, and as a result, the coating performance is stable; the tank body is completely mechanically coated in the curing furnace; the coating gun is inserted into the tank body to coat the whole inner wall of the tank body, and therefore, the tank body coating efficiency is raised; the coating is out of the limitation from human factors, so that the coating uniformity is improved.

Description

technical field [0001] The invention relates to the technical field of paint coating, in particular to a Teflon tank body coating equipment and a coating method. Background technique [0002] Teflon coating is a fluorine coating with polytetrafluoroethylene as the matrix resin. The English name is Teflon, and it is usually called Teflon, Teflon, Teflon, Teflon, etc. transliteration). Teflon coating is a unique high-performance coating, which combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has comprehensive advantages that other coatings cannot compete with. Its application flexibility makes it suitable for On products of nearly every shape and size. [0003] Teflon is divided into several basic types: PTFE, FEP, PFA, and ETFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260 ° C, with a maximum service temperature of 290-300 ° C, extremely low friction coefficient, good Wear resistance and ...

AI Technical Summary

Problems solved by technology

[0008] In the prior art, the Teflon coating on the inner wall of the tank is usually done manually by workers. The workers enter the tank and hold the coating gun to coat the inner wall of the tank. In the coating industry of Teflon There is no effective solution to complete the coating by mechanical means. Manual coating has the disadvantages of low efficiency and uneven powder coating, which also causes troubles for coating inspection after coating.

In addition, since the coating needs to be completed in a molten state, the Teflon coating needs to be carried out in a high temperature environment, and the workers need to wear heavy protective clothing during the coating process. The working environment of the workers is poor, which is also A factor that contributes to inefficiency

In the existing coating method, the coating site and the curing site are different areas separated from each other. The tank body after coating needs to be transported separately and placed in the curing equipment to complete the solidification of the molten powder. The position conversion process is easily affected by changes in the external environment, which leads to the instability of the physical properties of the forming coating, which in turn leads to the consequences of poor coating
