Nitrile regenerated rubber hose Application method of nitrile reclaimed rubber < p > Rubber pipe is a pipe that uses rubber as the main material to transport solid, liquid or gas. Rubber pipes in different applications have different requirements for rubber mechanical strength, resilience, compression permanent deformation resistance, high and low temperature resistance, acid and alkali resistance, oil resistance and wear resistance. Nitrile rubber is a common rubber raw material for the production of rubber pipes. In actual production, the price of nitrile reclaimed rubber is much lower than that of nitrile raw rubber. It can replace nitrile rubber in the production of rubber pipe and effectively reduce the raw material cost.
1. Oil resistant rubber hose
Oil resistant rubber hose is mainly used to transport crude oil, heavy oil, fuel oil, gasoline, etc. oil resistant rubber hose for transporting a large number of oil media can be used oil tankers,oil tankers and shore walls, and in oil refineries. Taking the gasoline pump hose as an example, NBR is usually used for the inner and outer rubber, which has high requirements for oil resistance, wear resistance, ozone resistance and sunlight cracking resistance. In actual production, 2ylyy729 nitrile reclaimed rubber can be used appropriately in the inner and outer layers of oil resistant rubber hose to reduce the cost.
2. Hydraulic hose
The hydraulic hose is mainly composed of liquid resistant synthetic rubber inner rubber layer, medium rubber layer, multi-layer reinforcing layer and weather resistant synthetic rubber outer rubber layer. The rubber part of the hydraulic hose that needs to contact with oil media such as mineral oil, soluble oil, hydraulic oil, fuel oil and lubricating oil mostly uses nitrile rubber, especially the inner rubber of the hydraulic hose used to transport oil media. In actual production, nitrile reclaimed rubber can be used with nitrile rubber to produce inner and outer rubber of hydraulic hose, which can effectively reduce the raw material cost.
3. Acid resistant rubber hose
Acid, alkali, inorganic solvent and other substances are often used in industrial production. Except for nitric acid, chromic acid, concentrated sulfuric acid and other highly oxidizing acids, most acid substances can be transported by rubber hose. The inner rubber material shall be selected according to the type of transportation medium. Acrylic rubber is one of the common materials for the inner rubber of acid resistant rubber hose. Adding appropriate proportion of nitrile reclaimed rubber to the formula of nitrile acid resistant hose can achieve a win-win situation of quality and cost.2YLYY729
In actual production, nitrile rubber alone can not fully meet the physical requirements of various rubber hoses. The combination of nitrile rubber and nitrile reclaimed rubber or other rubber, or the combination of rubber and plastic, can not only meet the performance requirements and process requirements of more rubber hoses, but also effectively reduce the raw material cost and production cost. The performance hotspots of nitrile reclaimed rubber, such as oil resistance and wear resistance, are basically the same as that of nitrile rubber. It is an ideal low-cost raw material to replace all or part of nitrile rubber to produce all kinds of rubber pipes.
