How does the polymer to chemical ratio affect the rubber material?

Litong LT799 ultra-high pressure resin cleaning hose uses nylon (PA) as the inner layer material, wound high-strength steel wire as the reinforcement layer, and black or colored polyurethane (TPU) as the outer layer of the hose. The working temperature ranges from -40℃ to Between 100°C, the maximum working pressure is as high as 320MPa (the inner diameter of the hose is 7.8mm), and the maximum burst pressure is 800MPa. It is the quality choice for users of extreme high-pressure cleaning hoses. In the wear-resistant hose, if there are certain requirements for safety and working pressure, it is generally used for type B (A, B, C, D pressure from low to high) wear-resistant hose: its working pressure is about 5MPa~7MPa It is usually used in occasions with certain requirements for safety. Due to its consideration of cost and safety, its price/performance ratio is relatively moderate.

 

The inner and outer rubber of the hose is made of synthetic rubber, and the wear resistance is guaranteed to a certain extent. Since the reinforcement layer will also use steel wire, the maximum blasting pressure is also improved to a certain extent. The Litong Party General Branch cooperated closely with the center, based on the grassroots organization, and focused on the role of the Party General Branch as a battle fortress, and launched a frenzy for creation. Branches learn advanced, strive for advanced and achieve advanced, prompting employees to set strict standards for themselves in production and life, and set a good example for other employees. In improving the overall quality of the company, everyone should do make an effort. To date, the company has 16 active invention patents and has announced 6 authorizations. So far, 16 provincial and prefecture-level scientific research projects and 9 provincial-level scientific and technological achievements have been completed. The company is the primary design arm for many industry standards. The company has 9 national invention patents and more than 20 new patents. Mastered many core technologies for manufacturing hydraulic hoses. In 2017, Litong throttle hose obtained API product certification (16C-0403).

 

Luohe Litong Hydraulic Technology Co., Ltd. was established in 2003. The company has successively obtained the certificate of the top 10 rubber hose enterprises in China according to the rubber industry measures. The company spends huge sums of money to import international advanced and first-class equipment such as Italian VP large-diameter steel wire winding machine, Finnish crimping machine, and vp plying machine, and has obtained fruitful reports while investing in research and development. Steel wire braided hose is an upgraded product of rubber hose, which is lighter, smaller in diameter, and more convenient to install. It is suitable for the transportation of various media and chemical materials. Steel wire winding pipes are mostly used in hydraulic ultra-high pressure transportation. The temperature is between -40°~+120°. The inner pipe is imported nylon, which is smooth and has low resistance. The reinforcing layer is high-strength steel wire, and the outer layer is made of elastic and durable Abrasive, weather-resistant material. Excessive temperature will accelerate the effect of chemicals on the rubber material, which depends on the ratio of polymer and chemicals.
