Talking about the six characteristics of fluorine plastic wire and cable

Fluoroplastic cable has excellent weather resistance, heat resistance, small friction coefficient, chemical stability, good electrical insulation properties. Therefore, fluorine plastic cables have important applications in the harsh environment of petroleum, metallurgy, chemical industry, electric power, aerospace and other industries. Fluoroplastics have a high degree of chemical stability and chemical resistance, fire resistance, high temperature resistance, flame retardant and other characteristics, so it has a wide range of applications in the wire and cable industry, special cables such as: high temperature resistant cables, flame retardant cables, corrosion resistant cables, etc. Most use fluorine plastic as the outer sheath.

Fluoroplastic wire and cable has the following characteristics:

1. Flame Retardant: Fluorine plastics have a high oxygen index, a small flame spread when burning, and less smoke generated. The cables made of them are suitable for places with strict flame retardance requirements, such as computer networks, subways, vehicles, high-rise buildings and other public places. Once a fire occurs, people can have a certain amount of time to escape without being smothered by dense smoke. To valuable rescue time.

2, excellent electrical properties: Compared to polyethylene, fluorine plastic dielectric constant is lower, so compared with the same structure of the coaxial cable, fluorine plastic cable attenuation is smaller, more suitable for high-frequency signal transmission, The increasing frequency of use of cables has become a trend. At the same time, due to the high temperature resistance of fluorine plastics, it is often used as a jumper and video audio cable between the internal wiring of transmission communication equipment, wireless transmission feeders and transmitters. In addition, the fluorine plastic cable has good dielectric strength and insulation resistance and is suitable for the control cable of important instrumentation equipment.

3. High temperature resistance: Fluoroplastics have extraordinary thermal stability, making fluoroplastic cables adaptable to high temperature environments of 150-200 degrees, while common polyethylene and polyvinyl chloride cables are only suitable for working environments of 70-90 degrees. . In addition, under the condition of the conductor with the same cross-section, the fluoroplastic cable can transmit more allowable current, which greatly improves the use of the cable. Because of this unique performance, fluoroplastic cables are commonly used in aircrafts, naval vessels, and high-temperature furnaces. As well as the internal wiring and lead wires of electronic devices.

4. Perfect mechanical and chemical properties: Fluorine plastics have high chemical bond energy, high stability, almost no influence of temperature change, excellent weather resistance and mechanical strength, and are free from all kinds of acids, alkalis and organic solvents. Because of the influence of materials, it is applicable to occasions with large environmental and climatic changes and corrosive conditions, such as petrochemical, oil refining, and oil well instrument control.

5, to facilitate welding connection: In the electronic equipment, there are a lot of wiring is used to connect the welding method, because the general plastic melting temperature is low, easy to melt at high temperatures, the need for skilled welding technology, and some solder joints must have A certain welding time, which has also become a reason for the popularity of fluoroplastic cables, such as the internal wiring of communication equipment and electronic instruments.

6. The price of fluorine plastic raw materials is high, and cable production is difficult: the production cost is high, and the selling price is naturally high, which also limits the application of the product. However, because of this, the competition manufacturers are less and need to use fluorine plastic cables. The customer will not be too concerned about the price factor.

Antique Shower Faucet in use function, as with the general Shower Faucet. The main features of the archaize faucet are the appearance advantages, and the appearance and decoration show a retro performance at any time. Not only has the antique flavor, but also revealed a noble and elegant. The retro design that incorporates the entire bathroom highlights the flavour of the times. Because of the outstanding decorative effect of the antique shower faucet, it is well liked by people, but the advantages of the Antique Faucet with different materials are different, and the effect of natural decoration is different.
