Teflon Spray High Performance Special Coatings

2020-12-19

Teflon spraying high-performance special coating is a fluorine coating based on polytetrafluoroethylene (all transliterations of Teflon). Teflon spraying high-performance special coating is a fluorine coating based on polytetrafluoroethylene (all transliterations of Teflon). PTFE spray coating is a set of heat resistance, chemical inertia, excellent insulation stability and low friction in one of the high-performance coatings, with other coatings can not be compared with the comprehensive advantages. The flexibility of its application allows it to be used in almost all shapes and sizes. PTFE spraying can be divided into several basic types: PTFE, FEP, PFA and ETFE. Teflon sprayed PTFE:PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260 ℃, with extremely low friction coefficient, good wear resistance and good chemical stability at 290 ℃. Teflon spray FEP:FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during the baking process to form a porous film, which has good chemical stability and excellent non-stick performance. The use temperature is 200 ℃. Teflon spraying PFA:PFA non-stick coating, like FEP, forms a porous film during the baking process. Its advantages are high continuous use temperature, use temperature 260 ℃, strong hardness and toughness, and is especially suitable for high temperature adhesion resistance and resistance. Chemical applications. Teflon Spray ETFE:ETFE is an ethylene-tetrafluoroethylene copolymer. The resin is a tough fluoropolymer that forms a durable coating, is chemically resistant, and can work continuously at 150°C.

Discussion on Teflon Spraying

Dispersion Coating Overview: The processing method of dispersion coating is to uniformly distribute the coating material in the solvent to form a dispersed liquid (solid material mixed in the liquid). This mixture is atomized by high-pressure air and sprayed on the surface of the workpiece. Preparation of the workpiece In order to obtain sufficient surface adhesion on the surface of the workpiece, all grease must first be removed from the surface to be coated. We dissolve the oil with an organic solvent and heat it to about 400°C to make it completely volatile. In the next step, the workpiece is cleaned and the surface is rough by sandblasting. The use of an adhesive (primer) can improve the binding ability of the coating to the surface of the workpiece. Powder spraying The powder particles are blown out of the collector by compressed air, and there is an electrostatic zone on the way to the spray gun nozzle. Because the particles carry the same charge, they repel each other in the flight path, forming a uniform cloud. The workpiece to be sprayed is ground so that an electrostatic zone is formed between the spray gun and the workpiece. The powder particles are attracted to and adhere to the workpiece. powder melting In coating technology, high-temperature spraying and low-temperature spraying are different in principle. If high temperature spraying is used, the temperature of the substrate is higher than the melting temperature of the powder material, and the powder particles are coated on it. The micropowder thus melts during spraying. In order to obtain sufficient surface adhesion on the surface of the workpiece, all grease must first be removed from the surface to be coated. We use an organic solvent to dissolve the grease and warm it to about 400°C to completely volatilize it. Next, the workpiece is mechanically cleaned and roughened by sandblasting. The bonding ability of the coating to the surface of the workpiece can be improved by applying an adhesion aid (primer). Teflon new material is located in Shenzhen Longgang area, is specialized in Teflon particles of enterprises. The introduction of advanced equipment and collection of technical personnel in the production of Teflon particles, with the concept of internationalization and sustainable management, with a serious implementation attitude, constantly improve the company's service quality, product quality, with an effective management system to strengthen the quality of all staff, in order to achieve customer satisfaction.

What is Teflon material

2021-04-28

Shenzhen Teflon New Material Technology Co., Ltd. was established in 2019, specializing in the manufacture of fluoroplastic raw materials. The main products are PFA, PVDF, ETFE, FEP, etc. The monthly production is stable and the supply is timely. In the process of rapid growth, Teflon New Materials has established a market action system and customer protection mechanism, and has always adhered to the business principles of maintaining customer relationships and integrity, and has a good reputation in the industry. Teflon is commonly known as Teflon (abbreviated as Teflon or [PTFE,F4]), known as/commonly known as "plastic king", also known as "Teflon", "Teflon" (teflon), "Teflon", "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound formed by the polymerization of tetrafluoroethylene, and its structure is-[-CF2-CF2-]n-. High temperature resistance-the use of working temperature of 250 ℃. Long-term use of temperature 200~260 degrees. Low temperature resistance-has good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain 5% elongation. It is still soft at -100 degrees. Corrosion resistance-for most chemicals and solvents, showing inert, strong acid and alkali, water and various organic solvents. Resistant to aqua regia and all organic solvents. Weather-resistant-has the best aging life in plastics. High lubrication-is the lowest coefficient of friction in solid materials. Has the smallest coefficient of friction in plastics (0.04). It's smoother than ice. Non-adhesion-is the smallest surface tension in a solid material and does not adhere to any substance. Non-toxic-physiologically inert, as a long-term implantation of artificial blood vessels and organs without adverse reactions. Aging resistance-radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged. Non-combustibility-limiting oxygen index below 90. Acid and alkali resistance-insoluble in strong acid, strong alkali and organic solvents (including magic acid, namely fluorine antimony sulfonic acid). Oxidation resistance-can resist the corrosion of strong oxidants. Insulation-excellent electrical performance, is an ideal C- class insulation material, a thick layer of newspaper can block 1500V high voltage. Its electrical insulation is not affected by temperature. The dielectric constant and dielectric loss over a wide frequency range are low, and the breakdown voltage, volume resistivity and arc resistance are high. Acid and alkaline-neutral.
