The internal liner of the wet acid process condenser cover is manufactured using modified fluororesin, resistant to concentrated sulfuric acid, as the main processing material. This material can withstand temperatures up to 150°C, and also has excellent aging resistance and anti-piercing properties, so it can resist corrosion of concentrated sulfuric acid and working conditions for a long time.
At the processing stage, rotational spray molding technology is used, which ensures integral single molding of the inner liner - after molding, its surface remains smooth and even, and the layer thickness consistently reaches 0.8 mm. The material has exceptionally strong adhesion to the base of the lid, so that during long-term operation there is no possibility of delamination, which guarantees tightness and safety of equipment operation.
