Abstract

The invention relates to an electrothermal conversion body coating formulation and an application method. The electrothermal conversion body coating formulation mainly comprises the following raw materials by weight percent: 35-50 percent of zinc chloride, 20-30 percent of tin chloride, 13-25 percent of graphite, 3-10 percent of copper carbonate, 2-6 percent of boric acid, 2-7 percent of ammonium fluoride, 1-4 percent of fluoboric acid and 1-4 percent of potassium dioxide silicon. The electrothermal conversion body coating formulation disclosed by the invention can be used for manufacturing various electrothermal conversion body heating elements on insulating materials in different shapes, such as silicon wafer electrothermal plates, mica electrothermal pieces, borosilicate glass electrothermal tubes, ceramic electrothermal tubes and the like, and can be widely applied to products and equipment, such as household appliances, industrial appliances and the like. The electrothermal conversion body coating formulation has the advantages of high electrothermal conversion rate, long service life, high heating power, low attenuation, simplicity in manufacturing and little pollution, and is suitable to be popularized and applied.

Description

technical field [0001] The invention relates to a coating and a using method, in particular to a coating of an electrothermal converter and a using method thereof. Background technique [0002] At present, there are two main types of electrothermal coating technology. One is the electrothermal film heating element made of graphite carbon fiber as the main material. It has good oxidation resistance, stable thermal power and simple processing technology. However, due to the poor thermal power performance of the carbon element itself, it cannot meet the requirements of high power and is easy to fall off, so its application field and scope are greatly limited. The other is to spray semiconductors, high chlorides and reducing agents on the surface of the insulator at high temperature to form an electrothermal film, which can realize a high-power electric heating body, high electrothermal conversion efficiency, no open flame for heat generation, and small thermal inertia. But its...
