Industrial paint manufacturers Xianghe Phosphate for your analysis of the misunderstanding of fluorocarbon paint procurement
Misunderstandings in the purchase of fluorocarbon paint    Â
1 , only recognize the price       Only know the coatings that are relatively cheap to purchase, but the coating rate of cheap coatings is often very low, which means that the cost per unit area is not cost-effective. And it is the age and effect, often the gap is great.  Â
2 , improper support   The fluorocarbon paint primer is improperly matched, and the result is usually that the performance of the paint can only be determined by a paint with poor performance.   Â
3 , only recognize the brand. Â Â Â Â Some people want brand products, they want to save money and cost-effective, so they buy ordinary products in high-end brands. The results are often not satisfactory. Â
4 , blind pursuit of water   The most important point in environmental indicators is the voc (volatile organic matter) content. Some manufacturers, although advertised as water-based paints, still emit pungent odor during use. Explain that the voc content is not low.   Â
5 , one-sided parameters       Some people think that the higher the viscosity of fluorocarbon paint, the more cost-effective it can be compared to thinner materials, without considering the effective ingredients of the paint. In fact, all the thinner materials blended in the paint will eventually volatilize into the air, and will not remain on the surface of the workpiece. The more the thinner materials are blended, the more waste is actually, and the environment is seriously affected. Therefore, low viscosity, high solid paint is the mainstream of industrial paint development.       Â
Under normal circumstances, the paint's solid content, impact resistance, weather resistance, adhesion, coating rate and other indicators should be comprehensively analyzed.

PTFE is principally used as a gasket material because of it's capability to remain unaffected by the majority of chemicals used in industry. It is also classified, in most cases, as a food grade material, making it acceptable to both medical and food production industries. There are three basic types of PTFE Gasket materials. Virgin PTFE , filled PTFE and expanded PTFE .Features
Acid and alkali resistant
Chemical resistant
Has minimum friction coefficient of all know pure material
Non-viscous, no aging
Now molds can be made according to customers requirements.
Virgin PTFE is by far the least expensive of the three varieties, and is used in most general applications. Filled PTFE is a gasket material with a virgin PTFE base to which a substance is added during manufacture to improve the sealing characteristics of PTFE . This "filler" usually is glass or graphite particles although ceramics has sometimes been used. The resulting gasket material is strong, yet highly compressible with very good, though not universal, chemical resistance.
Expanded PTFE is virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacture. This process ensures that the molecular chains from which the PTFE is constructed, do not arrange themselves into set patterns. This means that expanded PTFE possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required, expanded PTFE also possesses the unique chemical resistance of virgin PTFE.
