Hangzhou, 15268 Xiacheng Shiqiao Road Xinhua Economic Park 186621 has high temperature insulation paint Fan Lishui sales; the company is a very powerful agent in the country. The company's products include insulating varnish, electronic glue, potting glue, three anti-paint, insulating board, synthetic stone, etc.; insulating varnish is the use of non-conductive substances to isolate or enclose the charged body to protect the electric shock. Safety measures. Good insulation is the most basic and reliable means for ensuring the safe operation of electrical equipment and circuits and preventing personal electric shocks.

Insulating varnishes are generally classified into three categories: gas insulation, liquid insulation and solid insulation. In practical applications, solid insulation is still the most widely used and most reliable insulating material.

Under strong electric current, the insulating material may be broken down and lose its insulating properties. In the above three kinds of insulating materials, after the gas insulating material is broken down, once the external factor (strong electric field) is removed, the inherent electrical insulating property can be restored by itself; and after the solid insulating material is broken down, it is irreversibly completely lost. Its electrical insulation properties. Therefore, the insulation selection of electrical circuits and equipment must be compatible with the voltage level, and must be compatible with the use environment and operating conditions to ensure the safety of insulation.

Insulating varnish can reduce or even destroy the insulation properties of insulating materials due to corrosive gases, vapors, moisture, conductive dust and mechanical operations. Moreover, the long-term effects of environmental factors such as sunlight and wind and rain can also cause the insulating material to age and gradually lose its insulating properties. The insulation resistance of various lines and equipment under different conditions is as follows: Under normal circumstances, the low voltage after new or overhaul should not be lower than 0.5Ω; the low voltage line and equipment in operation should not be lower than the insulation resistance. 1000Ω/V; the insulation resistance of equipment and circuits in wet conditions should not be lower than 500Ω/V; the insulation resistance in the control line should not be lower than 1MΩ, and the insulation resistance of high-voltage lines and equipment should not be lower than 1000MΩ.

The high temperature resistant insulating varnish is made of proprietary inorganic-organic polymer binder, composed of inorganic crystal materials with high volume resistivity and compact structure, such as alumina, silicon nitride, etc., and the particles produced by our company are high temperature. The film-forming material is mainly composed of high temperature insulating varnish. Strictly control the proportion of raw materials in the production process to avoid the introduction of stray ions, especially alkali or alkaline earth metal ions; minimize the content of the glass phase, and minimize the conductivity of the glass phase added to improve the process performance. In the production process, attention is also paid to strictly controlling the introduction of variable-valent metal ions such as iron and cobalt to avoid the generation of free ions and holes. At the same time, the temperature and atmosphere in the production process are strictly controlled to avoid the occurrence of redox reactions and electrons and holes, preventing crystal lattice transition and crystal defects. High temperature resistant insulating varnish can be applied to various materials, curing at room temperature, curing time is more than 24 hours.

High temperature insulation paint:

The role of high temperature insulating varnish is to isolate the charged parts of different potentials in electrical equipment. Therefore, the insulating material should first have high insulation resistance and compressive strength, and can avoid accidents such as electric leakage and breakdown. Secondly, the heat resistance is better, avoiding deterioration due to long-term overheating; in addition, it should have good thermal conductivity, moisture resistance, high mechanical strength and convenient processing. According to the above requirements, the performance indexes of commonly used insulating materials include dielectric strength, tensile strength, specific gravity, and expansion coefficient.

Insulating varnish commonly used by electricians can be classified into inorganic insulating materials, organic insulating materials and mixed insulating materials according to their chemical properties. Commonly used inorganic insulating materials are: mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used as winding insulation for motors and electrical appliances, bottom plates and insulators for switches. Organic insulating materials are: shellac, resin, rubber, cotton yarn, paper, hemp, rayon, etc., mostly used to make insulating varnish, coated insulation of winding wires, etc. The hybrid insulating material is a variety of molded insulating materials which are processed by the above two materials, and are used as a base, an outer casing, and the like of an electric appliance.
