Abstract

The invention relates to a lower auxiliary system and a spraying process for a mixing workshop separant. The lower auxiliary system comprises a cooling section, a separant spraying section and a drying section which are arranged in sequence, wherein each of the cooling section, the separant spraying section and the drying section is provided with a conveying device; the cooling section comprises a cooling pond and a first draught fan arranged at the discharging end of the cooling pond; the drying section is provided with a second draught fan; and the separant spraying section comprises a separant pond, wherein the separant pond comprises a separant pond body, the outside of the separant pond body is sleeved by a condensed water jacket, a condensed water inlet and a condensed water outlet are formed in the condensed water jacket, an ultrasonic generator is arranged in the separant pond body, and separant nozzles are respectively arranged above and below the separant pond. Three rows of separant nozzles are arranged above the separant pond, three rows of separant nozzles are arranged below the separant pond, and three separant nozzles are arranged in each row. A graphene oxide water solution is suitable for use as a separant, so that the cost can be reduced, and the separating effect can be improved.

Description

technical field

[0001] The invention relates to a spraying process of a lower auxiliary machine system and a release agent in a banburying workshop, in particular to a spraying process in which a graphene oxide aqueous solution is used as a release agent in the tire banburying production process. Background technique

[0002] In the production process of rubber products, the viscosity of the mixed rubber is relatively high, and the rubber materials will stick to each other during the processing process, resulting in difficulties in processing and transportation. Therefore, before the rubber compound is finally made into a finished product, such as before handling and storing the rubber compound, extrusion, extrusion and hot mixing, a layer of release agent will be applied to the corresponding film to prevent the film from interacting with each other. Adhesion. There are many types of release agents, which have different effects on the performance of the glue. Traditional r...
