1. plastic thin hose price
The plastic western hose polytetrafluoroethylene is called "plastic king". Roy Planct, the father of fluorine resin, began to study freon substitutes in DuPont Company in 1936. They collected some tetrafluoroethylene and stored it in steel cylinders for the next experiment. However, when the pressure reducing valve of the steel cylinder was opened the next day, no gas overflowed. They thought it was air leakage, but when weighing the steel cylinder, they found that the steel cylinder did not lose weight. They sawed through the cylinder and found a large amount of white powder, which was Teflon.
Plastic thin hose Chinese trade name "Teflon" (teflon), "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound formed by polymerization of tetrafluoroethylene. Its structure is-[-CF2-CF2-]n-. It has excellent chemical stability and corrosion resistance. It is one of the best corrosion resistance materials in the world today. In addition to molten alkali metals, chlorine trifluoride, chlorine pentafluoride and liquid fluorine, it can withstand all other chemicals and will not change when boiled in aqua regia, it is widely used in all kinds of occasions that need to resist acid and alkali and organic solvents. Sealing, high lubrication non-stick, electrical insulation and good anti-aging ability, excellent temperature resistance (can be in the positive 250 ℃ to negative 180 ℃ temperature for a long time). Teflon itself is not toxic to humans. The use temperature is -190~250 ℃, allowing quenching and quenching, or alternating hot and cold operation. Pressure -0.1~6.4Mpa.
It has solved many problems in chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, gaskets. PTFE seals, gaskets, sealing gaskets are made of suspension polymerization PTFE resin molding. Compared with other plastics, PTFE has the characteristics of chemical resistance, it has been widely used as a sealing material and filling material.
Nowadays, all kinds of plastic king products have played a pivotal role in the national economy such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges. The use conditions of polytetrafluoroethylene (PTFE) industry chemical, petrochemical, oil refining, chlor-alkali, acid, phosphate fertilizer, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, iron and steel, atomic energy and polymer filtration materials, high-purity product production (such as ion membrane electrolysis), viscous material transportation and operation, food, beverage and other processing and production departments with highly strict hygiene requirements.

2. PTFE high temperature air pipe 200 degrees
The most famous high-temperature-resistant air pipe is fluorine plastic, of which polyfluoroethylpropylene is resistant to high temperature of 200 degrees, polyfluoroethylpropylene is resistant to high temperature of 260, and soluble polyfluoroethylpropylene is resistant to high temperature of 260 degrees. Among them, polytetrafluoroethylene is most commonly used in Milky White, followed by semitransparent and color. The only defect is that transparent PTFE pipe has not been developed yet. Poly fluorine makes up for the deficiency of poly fluorine, and the common color is transparent, followed by color. However, the shortage of soluble polytetrafluoroethylene is perfect. It is transparent and resistant to high temperature of 260 degrees, but the price is slightly higher.
High temperature resistant trachea polytetrafluoroethylene (F-46) is a kind of fluorine plastic developed to overcome the shortcomings of poor processing and molding performance of PTFE. It is a copolymer of polytetrafluoroethylene and polyhexafluoropropylene (F-6). Polytetrafluoroethylene propylene is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. The famous application of PTFE has the exterior wall material of Water Cube, which is the largest concentrated use in the world.
High temperature resistant trachea PTFE in addition to the use of temperature slightly lower than the PTFE, almost all of its excellent performance. Polyfluoroethylene propylene thermal fluidity, can be used in general thermoplastic processing methods, molding, extrusion, injection molding, etc., can also be made into anti-corrosion coating. Therefore, it is widely used in petrochemical anti-corrosion engineering.
There are many varieties of fluoroplastics, and they are being used more and more widely in petrochemical systems.
3. transformer bushing
Transformer bushing is the main insulation device outside the transformer box, the outgoing line of the transformer winding must pass through the insulation sleeve, so that the outgoing line between the outgoing line and the insulation between the outgoing line and the transformer shell, while the role of fixed outgoing line.
Due to different voltage levels, the insulating sleeve has the form of pure porcelain sleeve, oil-filled sleeve and capacitor sleeve. Pure porcelain bushing is mostly used for transformers of 10kV and below. It wears a conductive copper rod in the porcelain bushing and is air insulated in the porcelain bushing. Oil-filled bushings are mostly used in 35kV transformers. They are used to fill oil in porcelain bushings, wear a conductive copper rod in porcelain bushings, and the copper rod is coated with insulating paper. Capacitor bushing is used for high voltage transformers above 100kV and consists of main insulated capacitor core, outer insulated upper and lower porcelain, connecting sleeve, connecting sleeve, oil pillow, spring assembly, base, equating ball, measuring terminal, terminal, rubber washer, insulating oil and other components.
With the development of China's power industry, the power supply is increasing year by year, and power transformers are gradually developing in the direction of high voltage and large capacity. At the same time, due to the improvement of manufacturing technology, the insulation distance of each part of the transformer product is gradually reduced, so that the capacitor bushing as a transformer supporting product has stricter requirements on its appearance and size.
At present, many transformer bushings use Teflon tubes, because Teflon has excellent performance, meets the insulation conditions required for transformers, and has high temperature resistance, corrosion resistance, acid and alkali resistance, and friction resistance.

Transformer bushing polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), generally known as "non-stick coating" or "easy to clean material". This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, but also become an ideal coating for easy cleaning of the inner layer of the water pipe.
