In Baidu Encyclopedia, high-strength reclaimed rubber is defined as follows: High-strength reclaimed rubber refers to tire reclaimed rubber with tensile strength of 10-18MPA produced by scrap tires after grinding, desulfurization, magnetic separation, and blank sheet molding. High-strength wheel reclaimed rubber is mainly used in the production of various black high-strength, high wear-resistant rubber products, such as bridge bearings, engineering rubber, conveyor belts, triangle belts, etc.; however, these high-strength reclaimed rubbers produce some black rubber. Products, and the use of a relatively small range, are high-strength recycled rubber tire reclaimed rubber only? If you use reclaimed rubber to produce some light-colored high-strength rubber products or high-strength rubber products with special needs, how should you choose?
In a narrow sense, high-strength reclaimed rubber refers to a tire reclaimed rubber that strongly meets a certain standard (10-18 Mpa). However, in a broad sense, high-strength reclaimed rubber does not have restrictions on reclaimed rubber products. Not only tire reclaimed rubber, in other similar products, some reclaimed rubber products with high tensile strength can be called high-strength reclaimed rubber, such as:
1, high-strength latex reclaimed rubber: natural rubber waste rubber cups, rubber and other raw materials produced by latex reclaimed rubber products are very strong, generally can reach more than 16Mpa, this type of product we can see as high-strength latex reclaimed rubber, tensile strength Large white latex reclaimed rubber can replace natural rubber to produce light-colored high-strength rubber products; black high-strength latex reclaimed rubber can be directly used for various high-strength, high-wear-resistant automotive tires, conveyor belts, triangle belts, seals, etc. Molded rubber products significantly reduce raw material costs.
2, high-strength butyl reclaimed rubber: butyl reclaimed rubber is the main raw material waste butyl inner tube, waste butyl inner tube is usually divided in brand-name waste butyl inner tube and miscellaneous waste butyl inner tube, including the use of brand waste butyl inner tube production The butyl reclaimed rubber products have higher tensile strength, usually about 9Mpa, which is considered to be a high-strength reclaimed rubber compared with some common 7-8Mpa butyl reclaimed rubbers on the market! The biggest feature of butyl reclaimed rubber is its good airtightness. The use of high-strength butyl reclaimed rubber can be used to produce some high-tightness rubber products with high strength requirements, such as high-grade butyl inner tubes.
In addition, many special-purpose rubber products have high requirements for the oil resistance of products. For example, some rubber products that have been used in oil fields, gas stations, etc. for a long time are mostly replaced with nitrile regenerated rubber instead of nitrile rubber, which guarantees rubber. The oil resistance of the products can also significantly reduce the cost of raw materials, while the high-strength nitrile reclaimed rubber can be used as an ideal raw material for high-strength, high-oil-resistance rubber products; EPDM reclaimed rubber has excellent resistance to high and low temperatures and aging resistance. High-strength products can also be used to produce EPDM rubber products that require high strength.
Therefore, Xiao Bian thinks that for “high-strength reclaimed rubber”, we don’t need to over-exaggerate the truth, and it does not matter whether it is strong or not. It is hard to stipulate that only a strong MPA can be considered as “high-strength reclaimed rubber” and that it is to produce reclaimed rubber that produces high-strength rubber products. When selecting the type of reclaimed rubber according to the type of product and the range of use, consider the strength of the product. As long as the index can meet the requirements of your high-strength rubber products, you can. In the same kind of reclaimed rubber products, can the relatively high strength reclaimed rubber be called high-strength reclaimed rubber?
