Abstract
A method for cleaning a curing mold to be used for manufacturing elastomer articles, and in particular a cleaning method by removing curing residual of elastomer stuck to the mold without damaging the mold. The method for cleaning the curing mold includes a process of eliminating curing residual of elastomer stuck to the mold in a treatment vessel under plasma conditions.
Claims13
A method for cleaning a tire curing aluminum mold, by eliminating curing residual of elastomer containing organic ingredients, inorganic ingredients, or carbon blacks stuck to the mold, comprising the steps of;
- cleaning the tire curing aluminum mold, by oxidation reaction to decompose the curing residual into ash in a treatment vessel under plasma conditions so that the oxidation reaction occurs at a relatively low temperature, wherein said plasma conditions are a fixed atmosphere generated by charging electric voltage between electrodes with fixed high frequency electric power after filling the treatment vessel with reacting gas.
A method for cleaning a tire curing aluminum mold, by eliminating curing residual of elastomer containing organic ingredients, inorganic ingredients, or carbon blacks stuck to the mold, comprising the steps of;
- cleaning the tire curing aluminum mold, by oxidation reaction to decompose the curing residual into ash in a plasma generating furnace under plasma conditions so that the oxidation reaction occurs at a relatively low temperature, wherein said plasma conditions are formed by introduction of a fixed atmosphere generated by charging electric voltage between electrodes with fixed high frequency electric power after filling said plasma generating furnace with reacting gas.
