In industrial production, the tetrafluorospraying of production equipment or pipelines is one of the useful methods to prevent product corrosion. 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, tetrafluorospraying skills refer to the product to do FEP, PFA, ETFE, ECTFE and other 0.01-3mm thickness coating treatment, tetrafluorospraying with anti-adhesion, wear-resistant, smooth, clean, heat-resistant, and anti-corrosion functions. The pipeline products after spraying are no less effective than those lined with plastic pipes, so the tetrafluorospraying skills can be widely used in tableware, molds, cookware, household appliances, furniture, technology, automobiles, machinery, medicine.
According to regional experts specializing in the development and production of steel lined tetrafluoroidal pipeline equipment, the high-temperature curing process of spraying tetrafluoroidal coating is a key procedure for spraying tetrafluoroidal coating. 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, drop, and simple sintering flash, so that the mold shrinkage corrosion occurs, the appearance becomes rough, resulting in the mold scrap.
In the practical process of PTFE spraying, because the curing speed of the product is too fast, if the coating surface shrinks prematurely, resulting in a closed cell structure and high capillary internal pressure, the coating will eventually break. Therefore, the convex and convex curing temperature of the coating, the length of curing time and the speed of curing speed play a decisive role in the quality of the coating.
In the field of practical industrial departure, the reason why tetrafluorospraying skills can be widely used is that it has the following characteristics, which are described 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, and can maintain parts free from any kind of chemical corrosion.
3, sliding: PTFE spray film has a low coefficient of friction. When the load slides, the friction coefficient changes, and the value is only between 0.05 and 0.15. It is often used in mechanical rollers, hardware workpieces, etc.
4, function: Because the solid component of the paint is non-toxic, does not contain perfluoro-paintammonium, reasonable composition process, so the coating is non-toxic, widely used in cookware, medicine, food containers and so on.
5, non-sticky: Almost all substances do not bond with the tetrafluorospray film. Very thin film also shows a good non-adhesion function, widely used in baking molds and food industry, such as non-stick pans, cake pans and so on.
6, moisture resistance: the surface of the tetrafluorospray film is not stained with water and oil, and it is not easy to stick to the solution during production and operation. If there is a small amount of dirt, it can be wiped simply. Short downtime, save time and improve work efficiency.
7, heat resistance: Teflon film has excellent heat and low temperature resistance. It can withstand high temperature to 300°C for a short time, and can be used continuously between 240°C and 260°C, with obvious thermal stability, it can work at freezing temperatures without embrittlement, and does not melt at high temperatures.
