Paint knowledge | definition and composition of insulating paint

Core tip: lacquer is the general name of colloidal solution of film-forming substance in solvent Insulating paint is a kind of special paint Insulating paint is an important insulating material based on polymer, which can be solidified into insulating film or insulating whole under certain conditions It has passed UL and Rosh certification for environmental protection Insulating paint is generally composed of paint base, solvent or diluent and auxiliary materials According to the scope and form of use, it can be divided into four types: impregnating paint, covering paint, silicon steel sheet paint and anti corona paint Self drying insulating paint refers to the insulating paint which can dry itself into film after coating The mechanism of self drying is generally divided into three categories: one is volatile drying, that is, high molecular weight Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: paint is film-forming substances in the solvent of the colloidal solution Insulating paint is a kind of special paint Insulating paint is an important insulating material based on polymer, which can be solidified into insulating film or insulating whole under certain conditions It has passed UL and Rosh certification for environmental protection Insulating paint is generally composed of paint base, solvent or diluent and auxiliary materials According to the scope and form of use, it can be divided into four types: impregnating paint, covering paint, silicon steel sheet paint and anti corona paint Self drying insulating paint refers to the insulating paint which can dry itself into film after coating The mechanism of self drying is generally divided into three categories: one is volatile drying, that is, the high molecular weight solid resin dissolves in the appropriate solvent, the solvent evaporates after coating, leaving the solid film-forming resin This kind of insulating paint is easy to apply and fast to dry However, it has poor solvent resistance and is easy to soften when heated The second is oxidation drying This kind of insulating paint contains dry vegetable oil Under the action of oxygen in the air, the unsaturated double bond in the molecular structure of dry vegetable oil will self oxidize the cross chain, so as to achieve the purpose of drying General oil, phenolic resin and dry oleanolic acid resin insulating paint belong to oxidation drying insulating paint Due to the high content of vegetable oil and low heat resistance, this kind of insulating paint is class A and class E insulating material, with a long drying time, generally one day The third type is room temperature curing and drying This kind of insulating paint is cured by chemical reaction at room temperature This kind of paint is two-component or multi-component, now it is ready to use This kind of paint is commonly used, such as polyamide cured epoxy resin paint and two-component polyurethane paint This kind of paint has good heat resistance, solvent resistance and chemical resistance because of its chemical cross chain Insulating paint, commonly known as: fanlishui (self drying type, baking type, solvent-free type) insulating paint is based on high polymer, zs-1091 high temperature resistant ceramic insulating paint, which is divided into two types: solvent type with temperature below 600 ℃ and water-resistant type with temperature between 600-1700 ℃ The coating can form a ceramic coating with high volume resistivity on the surface of the object to be coated, which can withstand strong electric field without breakdown The coating has high mechanical strength and good chemical stability, can resist aging, water and chemical corrosion, as well as mechanical shock and thermal shock The coating can work continuously under the corresponding working temperature The most fundamental thing is to rely on strong technological innovation ability and make full use of the latest scientific and technological achievements of chemical industry, which mainly includes the following points: ① strictly control the proportion of raw materials in the production process and avoid the introduction of stray ions, especially alkali metal or alkaline earth metal ions ② : try to reduce the content of glass phase and the conductivity of glass phase added to improve the process performance ③: strictly control the introduction of iron, cobalt and other variable metal ions to avoid free ions and holes ④ At the same time, the temperature and atmosphere in the production process shall be strictly controlled to avoid the occurrence of electrons and holes due to oxidation-reduction reaction and crystal defects due to lattice transformation The product has been widely used in high temperature electric furnace, induction furnace, high temperature motor, fire-resistant device, motor, telecommunication equipment, high temperature equipment and other insulation The important insulating materials which can be solidified into insulating film or insulating whole under certain conditions are generally composed of paint base, solvent or diluent and auxiliary materials Paint house focuses on the decoration knowledge and effect map of coating,
