Nitrile recycled rubber is made of waste nitrile rubber products as the main raw material, processed through several key steps of crushing, desulfurization and refining, which retains the basic performance characteristics of the original nitrile rubber, excellent oil resistance, wear resistance, heat resistance, chemical corrosion resistance, and is a substitute for nitrile rubber to produce various oil pipes, seals, gaskets, rubber gloves, wear-resistant parts, rubber shoes, etc., effectively reducing the cost of raw materials. When using nitrile reclaimed rubber to produce low-cost rubber products, there are five key points to grasp to further optimize cost performance.
1. Reasonable design of nitrile recycled rubber product formula
When using nitrile reclaimed rubber instead of nitrile original rubber to produce different varieties of rubber products, it is necessary to consider the special needs of the product, such as oil resistance and wear resistance, and reasonably design the formula to improve product performance. For example, when producing oil-resistant seals with nitrile reclaimed rubber, it is recommended to choose nitrile reclaimed rubber and nitrile rubber with high acrylonitrile content to improve the oil resistance of the finished product; When producing wear-resistant rubber products with nitrile reclaimed rubber, an appropriate amount of wear-resistant fillers such as carbon black are added to improve the wear-resistant performance of the finished product.
2. Strictly control the processing conditions of nitrile recycled rubber products
When using nitrile reclaimed rubber to produce hot-pressed products, the operating temperature and vulcanization time directly affect the performance of the finished product, and it is necessary to set the appropriate temperature and time according to the characteristics of nitrile reclaimed rubber to ensure the fluidity of the rubber material and the full vulcanization reaction, and improve the quality and performance of the finished product.
3. Pretreatment of nitrile reclaimed rubber
When nitrile reclaimed rubber products need to be compounded, it is necessary to ensure the cleanliness of the surface of nitrile reclaimed rubber and improve the adhesion performance of the product through necessary pretreatment. For example, when nitrile reclaimed rubber is compounded with metal or other materials, the surface of nitrile reclaimed rubber can be sanded and cleaned to remove impurities and oxide layers on the surface, improve its adhesion to composite materials, and ensure the overall performance of composite products.
4. Sampling to test the performance of nitrile recycled rubber products
Sampling and testing of finished rubber products is a key link to ensure that product quality and performance meet standards. Through sampling and testing of finished products, the physical properties, chemical properties, durability and environmental protection indicators of the products can be evaluated, so as to ensure the safety and reliability of the products. Sampling performance testing is carried out on each batch of nitrile reclaimed rubber products, and potential problems are found and solved in time to ensure product quality and prolong service life.
5. Reasonable selection of nitrile recycled rubber product filler
When using nitrile reclaimed rubber to produce low-cost rubber products, the reasonable selection of rubber fillers can not only reduce the cost of raw materials and production energy consumption, but also improve the properties of the rubber compound, such as elasticity and hardness. When using nitrile reclaimed rubber E4LYY513 to produce soft rubber products, you can choose fillers with good flexibility such as silica to improve the elasticity and flexibility of the rubber compound; When nitrile reclaimed rubber products have high requirements for strength, high wear-resistant carbon black can be used, or steel wire, glass fiber, etc. can be directly added to improve the strength and rigidity of the rubber compound and meet the performance requirements of different products.
In the highly competitive rubber products market, nitrile reclaimed rubber has become the mainstream raw material for the production of rubber products instead of high-priced nitrile primary rubber by virtue of its excellent oil resistance, wear resistance and aging resistance, and is used in the production of seals, hoses, rubber rollers and other rubber products. Meet the needs of different application scenarios.
