An inorganic coating for preventing scaling and a method for preventing scaling on the surface of a heating element

Abstract

The invention relates to an inorganic coating preventing incrustation from being generated. The inorganic coating is prepared from, by mass, 4-16% of inorganic resin, 4-16% of organic solvent, 17-23% of aluminum oxide, 17-23% of titanium dioxide, 3-7% of crystal whiskers, 3-7% of kaoline and 26-34% of film formation accelerant. The inorganic resin, the organic solvent, the aluminum oxide, the titanium dioxide, the crystal whiskers and the kaoline are sequentially added into a grinding machine to be ground and mixed to form a first preparation, the grinding machine rotates at the speed of 500 r / min, and grinding time is 45 minutes; the film formation accelerant is a second preparation mixed with the first preparation before construction. The inorganic coating has the advantages of being completely formed by combining inorganic nanometer materials, being free from smell, free from pollution to water resources and air, low in sintering temperature, safe, high in flexibility and rigidity, good in self-cleaning property, high in non-sticky property and high in heat conducting coefficient, and having an infrared radiation function, and harm to the human body is avoided.

Description

technical field [0001] The invention relates to a material surface treatment material, specifically an inorganic coating for preventing scaling and a method for preventing scaling on the surface of a heating element. Background technique [0002] The invention is a material used for preventing scale generation on the surface of heating elements of metals, pottery and engineering plastics used in household, industry and military affairs. For example, if you boil a kettle for a long time, a thick layer of scale will grow on the inner wall. As the water fell to the ground, the trickles merged into rivers, passed through the mountains, and crossed the plains, scouring the soil and rocks, and dissolving many minerals. Ground water, such as well water and spring water, contains more minerals. If we drop a drop of water on a clean piece of glass, after the water drips dry, water marks will be left on the glass. This is the dissolved minerals in the water. [0003] Scale can be ...
