METHOD OF HYDROPHOBIC PTFE COATING ON THE ENAMELLED CARBON-STEEL HEATING ELEMENTS FOR GGH

摘要

A kind of method offer of the hydrophobic PTFE coating on the carbon steel heating element for being coated with enamel for GGH, wherein a good bumps is occurred in enamel coating layer. A kind of method of the hydrophobic PTFE coating on the carbon steel heating element for being coated with enamel for GGH is comprising steps of do the surface of the slightly enamel coating layer in first with blasting treatment, in order to increase the adhesivity of fluorine resin coating and enamel coating layer; Formed by spray with about 3-4mum thickness hydrophobic fluorine resin coating or immersing liquid a step, wherein as polytetrafluoroethylene fluorine resin component on the enamel coating layer being etched by containing therefore be sintered it is blocking it. Under 150 and 350 degrees Celsius of temperature, the liquid that wherein fluorine resin is contained is sprayed on enamel coating layer and is sintered blocking 5 minutes~24 hours.
