Nitrile recycled rubber has excellent oil resistance, good heat resistance and wear resistance, and can be used alone or in combination with nitrile rubber to produce industrial rubber products, effectively reducing raw material costs. What are the advantages of using nitrile recycled rubber in industrial rubber products? What industrial rubber products can be produced by nitrile recycled rubber? How much nitrile recycled rubber is suitable for industrial rubber products? What issues should be paid attention to during use?
1. Advantages of nitrile recycled rubber in the production of industrial rubber products
There are three main advantages to the production of industrial rubber products using nitrile recycled rubber:
(1) The price of nitrile recycled rubber is more than 50% lower than that of nitrile rubber, and the use of nitrile recycled rubber to replace part of the original nitrile rubber to produce industrial rubber products can effectively reduce the cost of raw materials and improve product competitiveness. (2) Nitrile recycled rubber retains the basic performance characteristics of nitrile rubber, oil resistance, wear resistance, heat resistance, corrosion resistance E5LYY1118, and can maintain key performance by replacing nitrile rubber to produce industrial rubber products; (3) Nitrile recycled rubber and original rubber have good dispersion, plasticity and fluidity, easy mixing and molding, moderate vulcanization speed, and the use of nitrile recycled rubber in industrial rubber products can improve the processing process performance of rubber.
2. What industrial rubber products can be produced by nitrile recycled rubber?
Nitrile recycled rubber has a wide range of applications in the production of industrial rubber products due to its excellent oil resistance and economic applicability.
(1) Nitrile recycled rubber has good oil resistance and wear resistance, and can produce auto parts such as auto tire linings, engine oil seals and gaskets, and the finished product can resist oil erosion and mechanical wear for a long time, extending the service life of parts.
(2) Nitrile recycled rubber has good oil resistance, wear resistance, heat resistance and air tightness, and can be used to produce rubber products such as oil-resistant rubber conveyor belts, hoses, rubber plates, sealing rings, sealing strips, shock absorbing blocks, etc.
(3) Nitrile recycled rubber has a large oil resistance coefficient and good wear resistance, and can be used to produce printing rubber rollers, and long-term contact with mineral oil, esters, and alcohol solvents can maintain good performance and less wear; Printing rubber roller manufacturers can also further improve the compression set of the compound through formula adjustment.
3. How much nitrile recycled rubber is suitable for industrial rubber products?
When using nitrile recycled rubber to produce industrial rubber products, the mixing ratio of recycled rubber needs to be determined in combination with the performance requirements of rubber products and the physical properties of NBR recycled rubber. low-cost oil-resistant shock absorbing blocks, sealing gaskets and other industrial rubber products can completely use nitrile recycled rubber; The proportion of nitrile recycled rubber in high oil resistance industrial rubber products is among 10% and 30%, such as high-quality oil seals and oil-resistant hoses; Generally, the proportion of NBR recycled rubber in oil-resistant rubber is among 30%-60%, such as oil-resistant sealing strips, sealing rings, etc.
4. Precautions for using nitrile recycled rubber to produce industrial rubber products
When using nitrile recycled rubber as the main raw material to produce industrial rubber products, it is necessary to combine the performance requirements and cost budget of rubber products to choose the appropriate nitrile recycled rubber, reasonably design the formula of nitrile recycled rubber products, strictly control the mixing process and vulcanization process, and pretreat some raw materials in advance, so that oil-resistant rubber products can take into account cost, oil resistance, wear resistance, strength, low compression deformation, etc.
It is recommended to choose nitrile recycled rubber with acrylonitrile content greater than 33% for high oil resistance industrial rubber products, and low sulfur and high promotion or peroxide vulcanization system for nitrile recycled rubber products with strict heat resistance requirements. When nitrile recycled rubber and original rubber are used together, segmented mixing, thinning and triangular packaging can be used to ensure uniform compounding. The temperature is high in summer, and it is recommended to shorten the vulcanization time of nitrile recycled rubber industrial rubber products by 5%-10%.
When using nitrile recycled rubber to reduce the production cost of industrial rubber products, we must choose the right recycled rubber and design the rubber formula reasonably, and the editor will continue to share with you the vulcanization formula and formula design points of different varieties of industrial rubber products produced by nitrile recycled rubber in the later stage.
