Share my views on the PTFE lining process. First choice

1. Raw materials, 2. Manufacturing process, 3. Testing.

The isostatic pressing process for PTFE is a relatively good method, right?

Raw materials, manufacturing process of the lining. It is better to extrude the lining in a paste form. It’s easy to tell just by touching it. The production standards also matter; European standards are the best, followed by American standards, with Chinese standards being the lowest. . . Manufacturers should look for well-known manufacturers.

I disagree with the opinion above regarding tightly fitted PTFE! I. Selection of tetrafluoro plates: There are domestic plates and imported plates; among the imported ones, we have brands such as Daikin and Wallcard from Japan, as well as DuPont from the United States! If it’s not for electronic-grade use, it’s recommended to opt for domestic products; after all, domestic circuit boards have, over the years, reached a level of quality that makes them fully suitable for use! II. Visual inspection of the equipment’s lining: First, ensure that the inner surface of the equipment is clean, free of dust and dark spots, with a smooth surface! III. Quality inspection: There are many details to consider here. 1. For the sealing of PTFE equipment, imported yellow adhesive is used to heat the PTFE sheets, and external force is applied to press the PTFE sheets tightly against the steel billet; it is difficult to ensure that all air between the PTFE sheets and the steel billet is removed in such a process! Here, smooth iron tools are used to tap gradually and listen to the sound in order to determine whether it is firmly attached! 2. When welding the joints between tetrafluoride plates, in principle, electric spark welding is used at a speed of no more than 10 centimeters per second; in practice, it also depends on the skill and precision of the technician During welding, the strength and quality of the weld are assessed step by step (the specific techniques used by the craftsmen will not be detailed here). In fact, the process of using PTFE for lining relies 100% on manual labor; the quality and appearance of the resulting product have nothing to do with well-known brands or large manufacturers – what matters most is whether the manufacturer possesses such a production technique! I really want to run an ad, but the boss in charge won’t allow it!
