High temperature resistant insulating paint

Effect

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. Its product range includes insulating varnish, electronic glue, potting glue, three anti-paint, insulating board, synthetic stone, etc. Insulating varnish is used to isolate or enclose charged bodies using non-conductive substances, providing protection against electric shocks. Good insulation is the most basic and reliable method for ensuring the safe operation of electrical equipment and circuits, as well as preventing personal electric shocks.

Insulating varnishes are generally classified into three types: gas insulation, liquid insulation, and solid insulation. In practical applications, solid insulation remains the most widely used and reliable type of insulating material.

Under strong electric current, insulating materials may break down and lose their insulating properties. Among these three types, once gas insulation breaks down, it can automatically restore its insulating properties after the external factor (such as a strong electric field) is removed. However, once solid insulation breaks down, it loses its insulating properties irreversibly. Therefore, when selecting insulation for electrical circuits and equipment, it must be compatible with the voltage level, usage environment, and operating conditions to ensure safety.

Insulating varnish can reduce or even destroy the insulation properties of insulating materials due to corrosive gases, vapors, moisture, conductive dust, and mechanical operations. Long-term exposure to environmental factors such as sunlight and rain can also cause aging and gradual loss of insulation properties. The insulation resistance of various lines and equipment under different conditions should be as follows: Under normal conditions, the low-voltage insulation resistance after new installation or overhaul should not be less than 0.5 MΩ; the insulation resistance of low-voltage lines and equipment in operation should not be lower than 1000 Ω/V; the insulation resistance of equipment and circuits in wet conditions should not be less than 500 Ω/V; the insulation resistance of control lines should not be less than 1 MΩ, and the insulation resistance of high-voltage lines and equipment should not be less than 1000 MΩ.

The high-temperature resistant insulating varnish is made from proprietary inorganic-organic polymer binders, combined with inorganic crystal materials like alumina and silicon nitride, which have high volume resistivity and compact structures. The particles produced by our company are designed for high-temperature applications. The main film-forming material is high-temperature insulating varnish. We strictly control the proportion of raw materials during production to avoid introducing stray ions, especially alkali or alkaline earth metal ions. We also minimize the glass phase content and reduce the conductivity of added glass to improve process performance. During production, we pay close attention to controlling the introduction of variable-valent metal ions like iron and cobalt to prevent the formation of free ions and holes. Temperature and atmosphere during the process are strictly controlled to avoid redox reactions, electron-hole generation, and crystal lattice transitions or defects. This high-temperature insulating varnish can be applied to various materials and cures at room temperature for over 24 hours.

The role of high-temperature insulating varnish is to isolate charged parts of different potentials in electrical equipment. Therefore, the insulating material must first have high insulation resistance and compressive strength to avoid accidents like electric leakage or breakdown. It should also have good heat resistance to prevent degradation from long-term overheating. Additionally, it should offer good thermal conductivity, moisture resistance, high mechanical strength, and be easy to process. According to these requirements, common performance indicators for insulating materials include dielectric strength, tensile strength, specific gravity, and expansion coefficient.

Electricians commonly use insulating varnishes that can be classified into inorganic, organic, and hybrid insulating materials based on their chemical properties. Common inorganic insulating materials include mica, asbestos, marble, porcelain, and glass, mainly used for motor and electrical winding insulation, as well as switch base plates and insulators. Organic insulating materials include shellac, resin, rubber, cotton yarn, paper, hemp, and rayon, mostly used to make insulating varnish and coated wire insulation. Hybrid insulating materials combine both types and are used as bases or casings for electrical appliances.
