Special hoses are hose products used for special media in conveyor belts. They mainly include oil-resistant hoses, acid-alkali-resistant hoses, heat-resistant hoses, hydraulic hoses, wear-resistant hoses, etc. The special rubber hoses used in different applications use different rubbers. Nitrile rubber has excellent oil resistance and is the main raw material for the production of various oil resistant hoses and fuel hoses.Nitrile reclaimed rubber, as a substitute raw material for high-priced raw nitrile rubber, can be used alone or in combination with nitrile rubber and other rubber and plastic materials to produce special hoses.
1. Ordinary oil resistant hose
Oil resistance is the biggest advantage of nitrile rubber. It is an ideal raw material for the production of oil resistant rubber products such as oil resistant rubber sheets, oil resistant rubber boots, and oil resistant rubber hoses. The appropriate amount of reclaimed rubber in the nitrile oil resistant rubber hose can effectively reduce the cost of raw materials. In actual production, you can completely use high rubber content nitrile reclaimed rubber to produce oil-resistant hose, or use nitrile reclaimed rubber 2YLYY831 and nitrile rubber in an appropriate ratio, or use nitrile reclaimed rubber/nitrile rubber/chloroprene rubber Combined use of rubber produces oil-resistant hoses with lower cost and better overall performance.
2. Rubber-plastic blended fuel hose
The nitrile rubber/PVC blend material has lower cost than pure nitrile rubber, and the vulcanized rubber has better weather resistance, ozone resistance, oil resistance, solvent resistance, chemical resistance, heat resistance, and flame resistance. Therefore, many manufacturers use nitrile rubber/PVC blend materials to prepare fuel hoses, such as automobile fuel hoses. The finished products have good performance and long service life. In actual production, nitrile rubber/PVC blending materials can use nitrile reclaimed rubber in an appropriate amount to further reduce raw material costs and production energy consumption.
In actual production, nitrile reclaimed rubber can also be used in the production of composite rubber fuel hoses, effectively reducing raw material costs.
3. Oil hose
Both the inner rubber and outer rubber of the oil pipeline can be made of nitrile rubber or nitrile rubber/PVC blending materials, and the appropriate amount of nitrile reclaimed rubber that is close to the index of the finished product is mixed, which is effective under the premise of ensuring product quality. Reduce raw material costs.
4. Nitrile rubber vent hose
The vent hose processed with nitrile rubber as the main raw material has excellent oil resistance, heat resistance, weather resistance, etc. Properly increasing the rubber content of the formula can further improve the oil resistance of the vent hose. When nitrile reclaimed rubber replaces some raw nitrile rubber to produce vent hoses, it is recommended to choose medium and high acrylonitrile reclaimed rubber to ensure the oil resistance of the nitrile vent hose while reducing costs. It should be noted that DBP will affect the oil resistance of the rubber compound. The amount of DBP plasticized nitrile rubber should be appropriately reduced.
The application of nitrile reclaimed rubber in special hoses is not limited to this. Later editors will continue to discuss related issues with you.
