Lex teaches you how to easily solve the problem of PVC hose selection?
PVC hose is a kind of industrial hose. It is made of PVC as the main material and added with certain auxiliary materials 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 Everyone is no stranger to the insulating effect of wrapping on the wire.
How do you choose PVC hose? The following editor of Hangzhou Haikuo Hose summarizes it for you.
First, the barrier properties of the material. If the packaged product is an extremely volatile content such as essential oils, we have to choose a five-layer co-extruded tube with an oxygen transmission rate of 0.2 to 1.2 units. Because this kind of hose has better barrier properties than ordinary ones.
Second, the stiffness of the material. Generally speaking, different packaging products of enterprises have different requirements on the stiffness of PVC hose materials. Under normal circumstances, high-density polyethylene is better than low-density polyethylene, and the required stiffness can be achieved early by adjusting the ratio.
Third, the choice of pipe materials. First of all, the materials must meet the requirements of relevant national health standards, and some harmful substances such as heavy metals must also be controlled within a reasonable range in accordance with regulations.
Fourth, the chemical resistance and weather resistance of the material. Similar to stiffness, high-density has better chemical resistance than low-density. Weather resistance must control the choice of varnish types and color masterbatch types.
PVC hoses are also widely used in construction. For example, after high-temperature heating, they can be molded into different kinds of casings, which can be used for the protection of electrical appliances and many circuits. In addition, municipal engineering also needs this material extremely. It can be said that its development prospects are very broad. Our country is also actively investing a lot of money to research new technologies. It can be seen that this kind of industrial hose will surely occupy a large share in the market in the future. .
