Industrial hoses are mainly used for soft connections between equipment. Compared with civilian hoses, they have many excellent properties. For example, their construction and operation environment is more complicated and they have excellent performances with better flexibility. According to the different working conditions, it can be generally divided into air, ventilation, suction and transportation, dust collection, anti-static extraction and so on. And it has a very wide range of applications, not only in industry but also in agriculture, covering fields such as oil, steam, fire protection and so on. The following editor will introduce the most commonly used hose in industrial hoses - PVC hose.
PVC hose is a kind of industrial hose. It is made of PVC as the main material, and then adds certain accessories to form a certain formula. The so-called PVC material is actually a general-purpose synthetic resin with a chemical composition of polyvinyl chloride, and it can be seen everywhere in our daily life. For example, it is widely used in electronics, and after the PVC hose is baked, it can be Everyone is not unfamiliar with the role of wrapping the wire as insulation.
PVC hose, industrial hose, PVC hose selection
So how do you choose PVC hoses? The following editor will summarize it for you.
1, the barrier properties of the material. If the packaged product is a highly volatile content such as essential oils, we must choose a five-layer co-extruded tube with an oxygen transmission rate of 0.2 to 1.2 units. Because this hose has better barrier properties than ordinary ones.
2, the stiffness of the material. Generally speaking, the stiffness requirements of PVC hose materials for different packaging products of enterprises will also be different. Under normal circumstances, high-density polyethylene is better than low-density polyethylene, and the required stiffness can be achieved early by adjusting the ratio.
3, the selection of pipes. First of all, the materials must meet the relevant national health standards, and some harmful substances such as heavy metals must be controlled within a reasonable range according to regulations.
4, the chemical resistance and weather resistance of the material. Similar to stiffness, high density is slightly more chemical resistant than low density. Weather resistance is to control the selection of the type of varnish and the type of color masterbatch.
PVC hoses are also widely used in construction. For example, after high temperature heating, they can be shaped into different types of casings, which are suitable for the protection of electrical appliances and many lines. It can be said that its development prospects are very broad, and this industrial hose will surely occupy a large share in the market in the future.
