This is used when the rubber hose, etc. are molded before vulcanization; in the process of molding the hose into the desired shape, the releasing agent is used as lubricant when inserting it in the rod. Adhesion-proof agent for rubber is used not to stick each other. Some of the examples are as follows. YS-2 (for low pressure) PG-67 (for high pressure) Anion surface active agent as a main ingredient and a specific additive are combined to improve thermal stability and water solubility. Without using any agents, cleaning can be made by water. According to the pressure applied to the hose, there are two types of releasing agent. PAAR-1 Anion surfactant and additive of polysaccharides endow a main ingredient with suspension stability. At the same time, addition of specific alcohol lowers surface tension and improves wetting property of rubber surface. High Carbon Steel Foil Steel Foil H According to the bending test after immersing the foil in the salt bath and quenching it, bath control can be done. (steel foil with C = 1.0%) Low Carbon Steel Foil Steel Foil K By this testing method, you can see the carbon concentration and carburizing ability of salt bath easily and promptly, so that the carburizing parameters can be adjusted. (steel foil with C = 0.1%)
