The ultra-high pressure rubber hose has one or more layers of steel wire braided outside the bellows, and is made of melted rubber. The two ends are usually equipped with joints and flange sleeves. Low temperature resistance (-196℃~+420℃), light weight, small size, good flexibility and so on. It is usually used to transport high temperature media such as corrosive chemical media, organic solvents, high temperature gas, hot oil, and low temperature or ultra-low temperature media.
The mortar, tailings and ore pulp left after the ore in the concentrator of the mining industry has been refined one after another will be discharged into the tailings pond for secondary use. The particle size of the mortar after refining is generally relatively small, generally between 50 meshes and 200 meshes, which is not bad with the size of sand, and contains water, which belongs to the medium of slurry particles. Therefore, the first factor to be considered when selecting the material of the mortar conveying hose is wear resistance. There are many kinds of pipes with good wear resistance in mines, such as ceramic composite pipes and wear-resistant rubber-lined pipes. Our company specializes in the production of super wear-resistant rubber hoses with high quality. Welcome to consult. Founded in 2003, the company has developed into a large-scale enterprise with an output value of 300 million yuan in just over ten years. It has introduced 10 advanced German Mayer steel wire winding machines, more than 20 advanced steel wire hose weaving machines, and Korean winding machines and other advanced production equipment. At the same time, the company It can independently develop and produce high-speed knitting machines, so that independent production can be controlled. In the international top product series, the introduction of advanced production equipment and experimental equipment, facing the high-end, insists on innovation. What are the advantages of PTFE hose?
1. Good insulation, can reach 1018 ohm/cm, not affected by environment and frequency, low dielectric loss and high penetration voltage;
2. The unique self-smoothing property of PTFE hose. It has the smallest friction coefficient among plastics, and is a better oil-free lubricating material;
3. The prominent appearance is not sticky. Does not stick to the surface of known solid materials, which are solid materials with small surface energies. In the superheated steam at 230°C, there is no change in appearance after nearly 100h. However, under the same conditions, fluororubber, silicone rubber, fluorosilicone rubber, butyl rubber, nitrile rubber, and natural rubber experience obvious deterioration in appearance after a short period of time. Since there are no polar substituents in the molecular structure of ethylene-propylene rubber, the molecular cohesion energy is low, and the molecular chain can maintain flexibility in a wide range, second only to natural rubber and butadiene rubber, and can still be maintained at low temperatures. Due to the lack of active groups in the molecular structure of ethylene-propylene rubber, the cohesive energy is low, and the rubber compound is easy to bloom, and the self-adhesion and mutual adhesion are very poor. In addition to the FDA certification, the inner rubber of the wine conveying hose needs to have good acid and alkali corrosion resistance. Because the wine contains special substances after fermentation, it is necessary to avoid its reaction with the rubber. In this way, in the process of conveying wine, under the premise that the medium is in contact with the pipe wall, the two will not react. FDA certification makes it use the highest grade.
