The inner wall types of rubber industrial hoses
Nylon fabric ventilation duct hose is a kind of gray scale high-temperature duct, nylon fabric duct points on the market sell several different material. Material is an important factor that decide the price. Different materials with different prices. So the customers don’t know what kind of good when choosing nylon ventilation duct hose. Next, I will introduce what are the influencing factors on the quality of the nylon fabric ventilation duct hose.
First, the quality of raw materials directly affects the quality of nylon fabric duct hose
The material of nylon fabric duct hose is mainly adopted by the cloth and the steel wire. The real nylon fabric produced stronger tube can withstand oil, acid, alkaline. But many manufacturers not use nylon fabric, but the ordinary PVC clip net cloth. Actually, it is very easy to distinguish from the appearance, nylon fabric density is higher, and looks like lattice screen cloth. Relatively, this kind of nylon mesh costs less, so the price is about two-thirds of that of nylon.
In addition, even nylon cloth, there are thickness points, 0.3mm, 0.4mm thick cloth, the thicker the cloth, the stronger the pressure resistance, of course, the service life will be higher. Except the cloth, the quality of the steel wire is also one of the important factors in determining the quality of nylon fabric duct hose. Nylon fabric ventilation duct hose using elastic steel wire to product. The use of steel wire hardness is high. Otherwise produced high temperature duct pressure is flat, and resilient steel wire to produce duct even crushed, also will rebound.
Second, the production technology is also one of the important factors affecting the quality of nylon cloth air duct hose
Remove material influence quality, process problems and affect the quality of nylon fabric duct hose is very important a factor. Nylon duct hose belongs to a duct through high temperature thermal production/ If the production technology is fail, it will be easily broken when heat sealing. But the stick is not sealed, will result in a breach air leakage problems. At the time of adhesive, once appear this kind of problem, so the whole tube is useless.
The nylon fabric ventilation duct hose is covered with nylon cloth and supported by spiral steel wire. The nylon cloth is hot pressed to bond the steel wire above and below to strengthen the adhesion and tension. It has high expansion and bending property, easy construction, strong acid and alkali resistance, good chemical resistance, easy to carry, oleic acid resistance and smoldering.
