Oils are usually non-polar, so rubbers containing polar groups such as nitrile rubber and neoprene have a large difference in polarity and have good stability to non-polar oils. Furthermore, the vulcanization system of the rubber has an important influence on improving the oil resistance. Generally speaking, the oil resistance increases with the increase of the crosslinking density, and the decrease of the free volume in the network structure makes the penetration and diffusion of oil difficult, thereby increasing the oil resistance. The impact of the high-pressure water flushing surface water generated by the high-pressure cleaning pipe plunger pump will be deprived of more than the dirt attached to the surface of the high-pressure water in the power plant and washed away, realizing a clean surface cleaning equipment. Because of the dirt cleaned with high pressure water jets, unless it is stubborn grease, the high pressure cleaning tube only needs to add a little detergent or general dirt with sufficient foam water pressure. In January 2013, won the title of "Top Ten Hose Enterprises in China" issued by the Rubber Hose and Tape Branch of China Rubber Industry Association, and participated in the Indian Construction Machinery Exhibition. On April 15, 2013, participated in the Canton Fair. The new restaurant for employees was completed and put into use, which greatly improved the dining environment for employees. In May 2013, Hannover Construction Machinery Exhibition, Germany, in July 2013, won the title of "Luohe Outstanding Innovative Enterprise" awarded by Luohe Municipal People's Government. The main domestic customers of Luohe Litong Hydraulic Technology Co., Ltd. are well-known domestic enterprises such as CNOOC and XCMG. These enterprises are well-known in all walks of life in China. The long-term cooperation with these enterprises also fully demonstrates the high quality of our company's products, and also represents that the company's products have been recognized in the industry, and the company's products are even exported to More than 20 overseas regions such as the United States and Singapore have laid a solid foundation on an international scale. 2. For hoses used to transport strong acid medium, the residual medium should be drained before cleaning to prevent frictional heat generation during cleaning. 3. There should be no residue in the hose for conveying colloidal medium after use, so as to prevent the hose from reacting when it is used next time. Nitrogen, steam or air can also be used to clean the hose, but the temperature should not be too high, and both ends of the hose are open to avoid damage to the hose. Litong Hydraulics is committed to the development and production of small molecules, which is conducive to improving the performance of rubber hoses. UHMWPE is manufactured and developed for abrasion, impact and corrosion resistance. The wear resistance of our raw tea tubes is more than double the life of ordinary tubes. Widely used in sandblasting and concrete transportation. The special performance has also been appreciated and recognized by many customers.
