1, high temperature baking.
2, chemical reagent wiping (a momentary solution).
3 beat hair surface (matt). Either change the overall formula, is inside the reagent oversaturation spray (precipitation) surface caused.
4, refining or vulcanising rubber inside the liquid or solid with the agent due to migration and precipitation on the surface of the rubber product to form a cloudy or white powder material phenomenon. This is due to sulfur paraffin, some antioxidants, softeners used in excess of their solubility in the rubber and caused. In order to prevent frosting, the dosage of the above agents should be appropriate, and insoluble sulphur can be used to prevent the common frosting of sulphur yellow. Appropriate addition of pine tar in the rubber, liquid Gumarone, etc. can increase the solubility of the rubber to the above agents to reduce the frost phenomenon.
5、According to the characteristics of raw rubber and compound, choose suitable high temperature vulcanisation temperature and time.
