What are the advantages of industrial vacuum hoses? What are the differences between PU and PVC vacuum hoses?
Industrial vacuum hose is a kind of high-tech product that appears in the world where we live with industrial vacuum cleaners. It is a type of industrial hose. The common ones are PU polyurethane material and PVC material, so what is PU hose? PVC hose should be clear to most people, so I won't say much. In addition, what is the difference between PVC and PU industrial vacuum hose? What are the advantages of industrial vacuum hose? Let's explain one by one. Industrial vacuum cleaners have the advantages of being able to use continuously for 24 hours, strong suction power, large dust storage volume, long service life, high temperature resistance, etc., especially industrial vacuum cleaners have almost no requirements for suction, various materials and various shapes of waste media Both can be absorbed. Through the adjustment of filter media, such as filter elements, filter bags, etc., solid particles with a precision of 0.1 micron can be absorbed, and it can be applied to fine chemical, precision machinery and other industries.
The advantages of industrial vacuum hose:
The first thing to say is that the inner surface of the industrial vacuum hose is very smooth, which allows us to use it without worrying about a large amount of dust and other sticking to the industrial vacuum hose due to the inner wall of the industrial vacuum hose. The inner wall causes the hose to be blocked. Because the inner wall of the industrial vacuum hose is smooth, the dust sucked in by the industrial vacuum cleaner generally does not collect on the inner wall, and usually follows the inner wall of the industrial vacuum hose into the vacuum cleaner dust storage bag for storage . Industrial vacuum cleaners are used in industrial production processes to collect waste, filter and purify air, and clean up the environment. Industrial vacuum cleaners can absorb all kinds of metal, non-metal, oil, water and other particulate dirt and liquids, can absorb toxic and harmful gases, can improve the quality of products in the textile industry, and can recover some expensive catalysts in the chemical industry. The woodworking industry can absorb wood dust generated during the production of woodworking machinery, and as a kind of environmental protection equipment, industrial vacuum cleaners can effectively prevent the hazards of some occupational diseases, such as pneumoconiosis.
Another advantage of industrial vacuum hoses made of PU material is that they are resistant to abrasion (a basic type of component failure) and have strong bending ability, which is 5 of the degree of wear resistance and bending resistance of different hoses. When using it, we usually don’t have to worry that the industrial vacuum hose will be damaged because we bend it or hit an object. Of course, we must be careful when using the industrial vacuum hose, not because of its wear resistance. And the ability to resist bending is strong, we don't care about using it, and if we don't protect and maintain it, it will only shorten the service life of the industrial vacuum hose.
What are the differences between PVC and PU industrial vacuum hoses?
PU industrial vacuum hose is made of PU plastic, PU is the abbreviation of Polyurethane, the Chinese name is polyurethane and abbreviated as polyurethane. PU pipes are widely used in machinery transportation pipes in the glass material industry, wood industry, steel industry, plastics industry, mines, shipbuilding industry, cement industry, etc., as strong protective tubes. At the same time, food grade tubes can also be used in the food industry and the pharmaceutical industry. This product can better meet the transportation requirements of all walks of life. The PVC dust suction pipe is made of PVC synthetic material, and the galvanized metal wire with extremely high strength is spirally embedded in the inner wall of the flexible PVC pipe. PU pipe and PVC are not very different on the surface. They are both transparent and embedded with steel wire. However, there is a huge difference between the two in terms of performance.
From the point of view of material quality, the vacuum pipe made of PU material is more pure and transparent than PVC pipe. The steel wire copper-plated steel wire embedded in the PU hose is more wear-resistant and tensile, and the steel wire of the PU hose is also The steel wire is thicker than that of the PVC dust suction pipe, which greatly increases the service life of the PU pipe. The service life of the PU hose is 7-10 times that of the PVC pipe. From the physical and chemical properties (parameters of chemical reaction), PU hose has high corrosion resistance, pressure resistance, abrasion resistance and high temperature resistance. These are far less than PVC pipes. In addition, PU hoses will not harden at very low temperatures in winter. It will not soften or turn yellow at high temperatures, which are unmatched by PVC pipes.
Through the above introduction, I hope to help you have a preliminary understanding of whether to choose a vacuum hose made of PU or PVC when purchasing an industrial vacuum hose.
