Haixin Color Coated Board Training Staff Product Knowledge
2022-09-27
Haixin let employees know about the coating of color coated boards, and the types of coatings used for the coating have different names, such as the primer coating is called the primer layer, and the finish coating is called the finish layer. Generally, the coating obtained by coating is relatively thin, about 20~50 microns, and the thick paste coating can obtain a coating with a thickness of more than 1 mm at a time. It is a thin layer of plastic coated on metal, fabric, plastic and other substrates for protection, insulation, decoration and other purposes. High temperature electrical insulation coating is made of copper, aluminum and other metals, or there is insulating paint, or plastic, rubber and other insulation sheaths. However, insulating paint, plastic and rubber are afraid of high temperature. Generally, if the temperature exceeds 200 ℃, they will gather and lose their insulating properties. And many wires need to work under high temperature, what should we do? Yes, let the high-temperature electrical insulation coating help. This coating is actually a ceramic coating. In addition to maintaining the electrical insulation performance at high temperatures, it can also be closely "united" with the metal wire to achieve "seamless". You can wrap the wire seven times and eight times, and they will not separate. This coating is very dense. When you apply it, two wires with large voltage difference will collide without breakdown. High temperature electrical insulation coatings can be divided into many types according to their chemical composition. For example, boron nitride or aluminum oxide or copper fluoride coating on the surface of graphite conductor still has good electrical insulation performance at 400 ℃. The enamel on the metal wire reaches 700 ℃, the phosphate based inorganic binder coating reaches 1000 ℃, and the plasma sprayed aluminum oxide coating reaches 1300 ℃, all of which still maintain good electrical insulation performance. High temperature electrical insulating coatings have been widely used in electric power, motors, electrical appliances, electronics, aviation, atomic energy, space technology, etc.
The steel plate of color coated plate is flat and rectangular, which can be directly rolled or cut from wide steel strip. The steel plates are divided into thin steel plates<4mm (the thinnest 0.2mm), thick steel plates 4~60mm, and extra thick steel plates 60~115mm. The steel plates are divided into hot rolled and cold rolled according to rolling. The width of the sheet is 500~1500 mm; The width of the thickness is 600~3000 mm. The thin plates are classified into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates; According to professional purposes, there are oil barrel plates, enamel plates, bulletproof plates, etc; According to the surface coating, there are galvanized sheet, tinned sheet, lead plated sheet, plastic composite steel plate, etc. The steel grade of thick steel plate is generally the same as that of thin steel plate. In all aspects of products, except for bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high pressure vessel steel plate, which are all thick plates, some steel plates, such as automobile girder steel plate (2.5~10mm thick), checkered steel plate (2.5~8mm thick), stainless steel plate, heat resistant steel plate, etc., cross with thin plates. In addition, the steel plate also has a material theory. Not all steel plates are the same. The materials are different, and the places where the steel plates are used are also different.
Through learning, the employees quickly mastered the basic knowledge of color coated boards, laying a solid foundation for their work.
