In industrial production, tetrafluoride spraying on production equipment or pipelines is one of the useful methods to prevent corrosion of products. However, the practical effect of tetrafluorospraying in different situations is often different. So, what are the specific characteristics of tetrafluorospraying skills in practice? Let's talk about it together.


From a professional point of view, tetrafluorspraying skills refer to the product to do FEP, PFA, ETFE, ECTFE and other 0.01-3mm thickness coating treatment, tetrafluorspraying has anti-adhesion, wear resistance, smooth, clean, heat resistance, and corrosion resistance. After spraying the pipe products are no less than plastic lined pipe in action, so the skills of tetrafluorospray can be widely used in tableware, mold, cookware, household appliances, furniture, technology, automobiles, machinery, medicine.


According to the experts who are specialized in the research and development of steel lined tetrafluoroethylene pipeline equipment, the high temperature curing process of spraying tetrafluoroethylene is the key procedure of spraying tetrafluoroethylene. If the curing depth of the coating is not good, the bonding strength of the coating is low, and the coating is simply broken and dropped. If the curing depth of the coating is too deep, the coating aging is also simple to crack, fall and simply occur in sintering flash, so that the mold shrinkage corrosion occurs, the appearance becomes rough and leads to the scrap of the mold.


In the practice of PTFE spraying process, because the curing speed of the product is too fast, if the coating surface shrinks prematurely, resulting in obturator structure and high capillary internal pressure, the coating will eventually break. Therefore, the concave and convex curing temperature, curing time and curing speed of the coating play a decisive role in the quality of the coating.


In the field of industrial departure in practice, the reason why tetrafluorospraying skills can be widely used is that it has the following characteristics, specifically introduced as follows:


1, wear resistance: under high load, with excellent wear resistance. Under certain load, it has the advantages of two layers of wear resistance and non adhesion.


2, corrosion resistance: Teflon is simply not corroded by drugs, can maintain parts from any kind of chemical corrosion.


3, sliding: PTFE spraying film has a low friction coefficient. When the load slides, the friction coefficient changes, and the value is only between 0.05 and 0.15. Often used to mechanical roller, hardware workpiece, etc.


4, Function: Because the solid component of this coating is non-toxic, does not contain perfluorophoronium, reasonable composition process, so the coating is non-toxic, widely used in cookware, medicine, food containers and so on.


5, not sticky: almost all substances do not adhere to the tetrafluoroidal spraying film. Very thin film also shows good non-adhesion function, widely used in baking mold and food industry, such as non-stick pan, cake pan, etc.


6. Moisture resistance: the surface of the tetrafluoroidal spraying film is not stained with water and oil, and it is not easy to stick with solution during production operation. If there is a few dirt sticks, it can be wiped simply. Short down time, save time and improve work efficiency.


7, heat resistance: Teflon film has excellent heat and low temperature resistance. Short time can withstand high temperature to 300°C, as in 240°C~260°C can be used continuously, with obvious thermal stability, it can work at freezing temperature without embrittlement, at high temperature does not melt.
