Points for Attention in the Use of Roller PTF

People are not very unfamiliar with roller coating PTFE. Today, the editor will expand your knowledge and take you to a detailed understanding of the key points of using roller coating PTFE. Come and follow the editor to take a look.

1. Do not have negative pressure. Negative pressure in the pipeline should be avoided when rolling PTFE. If there is negative pressure, the fluoroplastic lined layer of the valve cavity will be sucked out, swelled, and shelled, which will cause the valve to open and close to malfunction;

2. The pressure and differential pressure should be controlled within the allowable range. Especially fluorine plastic lined regulating valve and stop valve sealed by bellows. Because the bellows is made of PTFE material, the pressure and pressure difference are large, and it is easy to cause the bellows to rupture;

3. The medium conditions used for rolling PTFE should not contain hard particles, crystals, impurities, etc., so as to avoid the valve core, the fluorine plastic layer of the valve seat or the PTFE bellows from being worn out during the opening and closing of the valve. For the medium with hard particles, crystals and impurities, when selecting, the valve core and valve seat can be changed to Hastelloy.
