What are the materials needed for the production of inner tubes and pads?
The structure of tire in the world has been developed in the direction of tubeless, radial structure, flat (smaller ratio of height to width of tire section) and light weight. The tire tread, sidewall, buffer layer (or belt), ply and bead. Used to withstand various forces. The tread is the adhesive layer on the outer ply of the tire side and is used to protect the carcass. The ply is a fabric layer made up of tied rubber cord in the carcass, which is the force skeleton layer of the tire to ensure the necessary strength and dimensional stability of the tire. The buffer layer (or band layer) is the rubberized layer or adhesive layer between the tread and the carcass of the bias tire, used for buffering the external impact force, protecting the carcass, and enhancing the adhesion between the tread and the ply. The tyre ring is a part of the tyre mounted on the rim, consisting of a bead core and a bead wrap. Tire specifications to tire bead diameter D, diameter D or rim diameter and section width B and flat ratio (H / high tire tire section width B) size so that the unit is generally inches (in) (1in = 2.54cm). Automobile tire is a composite product of rubber and fiber material and metal material. The manufacturing process is a comprehensive process of mechanical processing and chemical reaction. Rubber and compound mixing after extrusion made of tread ply; after the rolling, cutting and bonding of cord drum or cord wire stranding, by volume; rubber molding for the bead; then all semi-finished products in the molding machine assembled on the green tire in vulcanizing machine, metal model, the sulfide made of finished tire.
Tires are often used in complex and demanding conditions. They are subjected to various deformations, loads, forces and high and low temperatures while traveling. Therefore, they must have high load-carrying performance, traction performance and cushioning performance. It also requires high wear resistance and flex resistance, as well as low rolling resistance and heat build-up. Half of the world's rubber consumption is used in tire production. Tires are usually composed of 3 parts of tyre, tyre, cushion belt. The inner layer of the fetus body has the rubber layer with good air tightness, and a special wheel rim is required
A ring shaped elastic rubber product that is grounded and mounted on various vehicles or machinery. The utility model is usually arranged on the metal rim, can support the vehicle body, buffer the external impact, realize the contact with the road surface, and guarantee the driving performance of the vehicle.
