Used Tread Rubber Buffing Machine For Tire Regrooving Equipment
Concepts of cold retreading:
The low temperature is against the high hot retreading temperature. Generally, 120°C is the denatured point of rubber, over called hot retreading, blow called cold retreading. And more advanced technology allows the temperature below 100°C. Because of the high temperature produce a negative effect to the tyre, the cold retreading is more and more popular.
Precure retreading means the tread should be procured by the high-pressure vulcanizing machine separately, while the hot retreading means the tread and casing are made up with non-vulcanized rubber, so the tread pressure is far below than the cold retread technology. Therefore, wear resistance, mileage of cold retread tyre can be comparable to the new tires, and flat mould can make tread with kinds of patterns, help the users to choose the more suitable patterns. However, it will be a big expense if you change tread patterns with hot retreading technology.
First process name: precure tread rubber
Conformable tire: The sidewall rubber still very good but tread rubber was worn down but not damage the steel belt.
Process: buffing machine grind off the rest tread rubber then brush glue, put new tread rubber on it, at last put the tire on curing chamber heating and vulcanizing.
Second section name: casing tread rubber
Conformable tire: The sidewall rubber still very good but tread rubber was worn down and damage the steel belt.
Process: rubber cutting machine remove the tread rubber with steel belt, named casing, and cover a new casing, at last put the tire on curing chamber heating and vulcanizing.
Third section name: old tread rubber
Conformable tire: the tread rubber still good but tire explode damaged the sidewall rubber.
Process: rubber cutting machine remove the casing or tread rubber, if remove the casing, used for casing tread rubber section, if remove the tread rubber, used for precure tread rubber section.
