Discussion on the advantages and disadvantages of the lining process
Thread Content
Common lining processes: The common processes are spraying, rolling coating, and sheet lining. When consulting suppliers, most of them only talk about the advantages and avoid mentioning the disadvantages. We welcome discussions on the advantages and disadvantages of various processes, so that we can make the right choice

This is merely for discussion purposes, to stimulate further conversation: 1. Spraying: 1) The coating is thin and has poor density, which may lead to leakage issues with small molecules； 2) Poor repairability once damaged. 3) Not resistant to negative pressure. 4) Not wear-resistant. 2. Roll coating: 1) Resistant to negative pressure. 2) Not wear-resistant. 3) It is difficult to remove the coating from the substrate when repainting. 3. Plate lining: 1) Relatively wear-resistant due to its certain thickness. 2) The weak point is at the welds; leaks are likely to occur at these areas, and the temperature resistance is limited by the welds. Experts are welcome to make corrections
It indeed cannot withstand negative pressure; we’ve suffered a lot in this regard
Comparing powder coating to painting, I think the quality of spraying will be more reliable in this case
The permeability of small-molecule materials, as well as their wear resistance, are not good enough
