Reclaimed rubber and reclaimed rubber powder belong to the recycling resource of waste rubber and occupy a large share in the field of rubber products. However, the two are essentially different, and Xiaobian together today to see the difference between reclaimed rubber and reclaimed rubber powder!
1, from the appearance point of view: Reclaimed rubber is generally a massive solid, renewable powder for the powder.
2, from the production process to see: Reclaimed rubber production methods are mainly oil method (direct steam static method), water and oil method (cooking method), high temperature dynamic desulfurization method, extrusion method, chemical treatment method, microwave method. China now mainly used in the production of reclaimed rubber oil method, water oil method, and high-temperature dynamic desulfurization method; renewable rubber powder production process at room temperature crushing method, cryogenic grinding method, water impact method. Compared with reclaimed rubber, rubber powder production process consume less energy, the process is simpler than reclaimed rubber.
3, from the internal structure of view: reclaimed rubber is chemically prepared products, the molecular chain was severely damaged; reclaimed rubber powder generally use the physical and mechanical force, the surface of the waste rubber products will be ground in powder separated molecules within The structure has not been severely damaged.
4, from the performance point of view: recycled rubber are desulfurization rubber, re-plasticity directly secondary vulcanization; recycled rubber powder is not desulfurized rubber, can not be secondary vulcanized, it is generally not in rubber products as the main rubber raw materials.
5, from the use point of view: Reclaimed rubber can be used as the main material for the production of rubber products, such as: latex reclaimed rubber can replace the production of sports soles natural rubber, color tires, plastic plates, tape and other products; EPDM replaces the ternary B C propylene rubber production of plastic strips, hoses, wire and cable and other EPDM rubber products; butyl rubber reclaimed rubber production of butyl tubes; nitrile rubber reclaimed rubber production of various products.
Reclaimed rubber powder generally only plays a role of filling and auxiliary, usually as a flexible filler to reduce costs, or as a functional processing aids to improve the process. Such as activated or modified rubber powder can be made of a variety of rubber products such as car tires, conveyor belts, fenders and dust cover, soles, flexible bricks, laps and pads; with asphalt or cement for road construction and housing Construction; plastic and can be used in conjunction with the production of waterproofing membrane, agricultural water infiltration irrigation pipe, muffler panels and floors, pipes, packaging materials, frames, bathtubs, water tanks; can also be used for the production of paints, paints, adhesives and production of activated carbon.
