Wear resistance evaluation of EPDM rubber as hose material

From October 15th to October 17th, 2019, "Litong Liquid Intelligent Industry Base Launch Ceremony and New Product Exchange Meeting", "Litong Liquid Intelligent Industry Base Operation Festival and Project Investment Exchange Meeting", “Litong Liquid Intelligent Industrial Base Groundbreaking Ceremony”, “16th Anniversary Celebration” “This is also a grand event in Xinxiang City. Everyone joined this large meeting to share the joy of the holidays, to celebrate the major achievements of the past 16 years, and to hope for an impressive fine art painting. Nowadays, the high-pressure wear-resistant rubber hose has a rapid development trend, and its quality is constantly improving. At the same time, wear-resistant and flame-retardant rubber hoses are also widely used in crude oil, chemical plants, deep sea, metallurgical industry and other fields. The high-pressure wear-resistant rubber hoses produced by our company are widely praised by five-star countries all over the world, and have won many honorary awards from the state, carrying the flag of China's wear-resistant pipeline field. The tolerance of different media is different. The material of the heat-resistant steam hose is EPDM rubber, EPDM plastic, EPDM EPDM rubber is a very good plastic for water vapor, and the heat-resistant steam hose is for oil. , Mineral oil, aromatic oil is not tolerated, it has a certain bearing effect on air drying gas, but it is not ideal. Chlorine chlorinated high pressure polyethylene plastic can be used. You can also use silicone, but silicone rubber is not easy to bond with the enhanced layer.  Xinxiang Litong Hydraulic Press Technology Development Co., Ltd. is engaged in manufacturing, product development , Marketing and sales of high-pressure hoses and liquid couplings has been in the industry for 18 years. It is an industry-recognized high-quality high-pressure hose manufacturing and service company. The stable product quality and good user evaluation have won the honorary title of "my country's Top Ten Rubber Hose Companies" awarded by the China Rubber Industry Association Rubber Hose and Tape Federation for 9 consecutive years. The company currently has 400 employees, including 80 in the R&D department, 55 experts, professors, doctoral supervisors, postgraduates and above. The company has completed 16 provincial and municipal scientific research projects, and has 14 patented inventions and 17 design patents. , 9 provincial and ministerial scientific research achievements. Litong built a CNAS verification laboratory - Henan High-Pressure High-Pressure Hose Engineering Design Institute, and cooperated with Qingdao University of Science and Technology to establish Litong Qingdao Research Laboratory.

Sandblasting hose has a particularly critical effect in the industry. Among them, viscose plus carbon black can reasonably eliminate static electricity and immediately contact with air compression and wear-resistant materials. The requirements for wear resistance are very high. Once Worn out, the raised layer is exposed and the sandblasting tube cracks. The raised layer of the sandblasting hose is a compression-resistant layer, so the raw material and reasonable layout of the raised layer immediately determine the compression-resistant level of the sandblasted plastic hose. The common raised layers are braided hose raised layers and surrounding raised layers. Most of the sandblasting plastic hoses with a nominal diameter of 50mm or higher are used in construction sites where sandblasting pipes are required to be connected, so as to reduce the loss of working pressure in the sandblasting plastic hoses and ensure the routine development of shot blasting and carding projects.  Litong rubber hoses have always been favored in the field of mining mineral resources. The natural environment of coal mining is complex, and the service life of rubber hoses is a big test. In order to better make rubber hoses routinely used in harsh environments , The elite team of Litong scientific research has worked hard, and the product has developed UPE high wear-resistant concrete transport plastic hose. It solves the difficulty of transporting concrete by construction machinery and equipment such as concrete pump trucks and mortar sprayers in engineering buildings. The characteristics of UPE enable rubber hoses to resist acidic chemicals in concrete.
