Among the reclaimed rubber products that have emerged at present, the tire reclaimed rubber is the most commonly used product. It is a universal reclaimed rubber. It is a reclaimed rubber that is processed from used tires as a raw material, has a certain degree of plasticity, and can be recycled. It can be partially replaced. Raw rubber is used in the production of rubber products to reduce the amount of raw rubber and carbon black, improve the processing properties of rubber compounds and certain properties of rubber products, and significantly reduce the cost of raw materials. In general, the raw materials and uses of tire reclaimed rubber of different manufacturers and different specifications are different.
Judging from the waste tire parts used in tire reclaimed rubber, the tread reclaimed rubber products processed from scrap tire treads are the highest in rubber content. The strength and wear resistance of the products are the highest among all tire reclaimed rubber products. Good; all-round reclaimed rubber produced from waste-tire radial tire carcass rubber is better than recyclable rubber produced from waste tire sidewalls as raw material and reclaimed rubber produced from tire waste. The index should be high, second only to the tread reclaimed rubber. The most common tire reclaimed rubber in the market is a full-cycle reclaimed rubber. The waste tires used in reclaimed rubber factories are imported 900-1200 waste tires, domestic 900-1200 waste tires, and various mid-to-lower tires. There are also differences in the indexes of tire top reclaimed rubber and full-cycle reclaimed rubber produced by different types of waste tires.
From the perspective of the regeneration process, the regeneration process of tire reclaimed rubber is to break some of the molecular chains and crosslinking points of the vulcanized rubber under the combined action of plasticizers (softeners and activators), oxygen, heat and mechanical shearing. process. During the entire regeneration process of tire regenerated rubber, the softening agent expands and plasticizes. Commonly used are coal tar, pine tar, petroleum softeners, and cracked residue oil; activators can shorten the regeneration time, and the amount of softener can be used to increase tires. Regenerated rubber hardness, common activators are aromatic thiols and their zinc salts and aromatic disulfides. Rubber product manufacturers can judge and select the right tire reclaimed rubber based on the demand of rubber products.
Generally, tire reclaimed rubber can replace natural rubber or general-purpose synthetic rubber to produce hoses, rubber strips, automobile tires, wire and cable jackets, seals, indoor floors, or fully reclaimed rubber to produce mat rubber sheets, rubber miscellaneous pieces, etc., significantly reducing Raw materials cost of rubber products.
With the continuous improvement of reclaimed rubber production equipment and production technology, tire reclaimed rubber is not only used as a universal reclaimed rubber, but gradually high-strength tire reclaimed rubber, environmentally friendly tire reclaimed rubber, ultra-fine tire reclaimed rubber and other special regeneration As a rubber product, Hebei Hongyun Reclaimed Rubber Factory is a well-known special rubber research base in China. The strength of the high-strength tire reclaimed rubber is as high as 16.5 Mpa, the fineness of the ultra-fine reclaimed rubber is more than 80 mesh, and the environmentally-friendly reclaimed rubber passes the EU ROHS environmental protection certification. Rubber manufacturers replace natural rubber, raw rubber production of rubber products to reduce raw material costs a good partner.
