The insulating varnish used for the impregnation treatment of the stator of electric tools belongs to the liquid resin system.
When dipping, through a certain dipping process, it penetrates and fills into the pores of enameled wires, wire grooves or other insulating parts.
After heating and curing, Zhisheng Weihua insulating coating bonds various parts into a whole and forms a continuous insulating layer.
Play the role of insulation, protection, bonding and isolation of external humid air.
my country's power tool industry is developing rapidly, and its output has leapt to the forefront of the world.
However, most of the insulating impregnating varnishes used by various domestic motor manufacturers in the insulation impregnation process contain a large amount of toluene, xylene and other flammable, explosive, toxic and harmful solvents, which will inevitably cause environmental pollution and damage to the factory.
The personnel suffered health damage.
With the continuous improvement of national environmental protection requirements and the promulgation of various environmental protection laws and regulations, the research of environmentally friendly insulating coatings, especially water-soluble insulating coatings, is being valued by more and more people.
The rapid development of industry, the continuous improvement of the requirements for insulating materials, the continuous improvement of the performance of insulating materials, the use of new technologies and new materials, breaking the conventional thinking research and development model, after years of research and development, tens of thousands of temperature resistance and insulation tests, Fengtai Beijing Zhisheng Weihua Chemical Co.
's ZS-1091 water-soluble high-temperature resistant insulating paint can withstand temperature up to 1800°C.
It adopts a special high-temperature solution, water-based inorganic high-temperature paint, and is water-based and environmentally friendly without any volatile matter.
The coating is composed of high-resistance inorganic crystal materials, such as α-alumina, silicon nitride, high-grade mica flakes, etc.
as fillers, the coating is dense and the hardness is high.
In addition, the production environment of ZS-1091 high temperature resistant insulating varnish is strictly required.
During the production process, the ratio of raw materials is strictly controlled to avoid the introduction of stray ions, especially alkali metal 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, pay attention to strictly control the introduction of variable valence metal ions such as iron and cobalt to avoid free ions and holes.
At the same time, strictly control the temperature and atmosphere in the production process to avoid the occurrence of electrons and holes due to oxidation-reduction reactions, and to prevent the occurrence of crystal lattice conversion and crystal defects.
ZS-1091 high temperature resistant insulating paint can be painted on various inorganic materials, cured at room temperature, and the curing time is more than 24 hours.
High temperature resistant insulating varnish has high volume resistivity, greater than 1016Ωm at room temperature.
High dielectric strength (breakdown strength), greater than 104KV/m.
High temperature resistant insulating varnish has good chemical stability, aging resistance, corrosion resistance, and oxidation resistance Good sex.
No flash point, ignition point, high hardness, hardness greater than 7H.
Heat resistance 1700℃, can work under 1800℃ for a long time.
ZS-1091 high temperature resistant insulating varnish has no volatilization, no odor at room temperature and high temperature.
Through the analysis of the above-mentioned ZS-1091 high-temperature resistant ceramic insulating coating, the organic-inorganic hybrid coating formula makes full use of the good welding performance and heat resistance of the inorganic film and the water resistance, insulation, impact resistance and adhesion of the organic film.
Moreover, it belongs to the water-based coating system, which has taken a big step towards the direction of environmentally friendly green products.
The performance of ZS-1091 water-soluble ceramic insulation coating can meet the insulation treatment requirements of small and medium motors, micro motors, stators, rotors, coils, armatures, transformers and iron cores in continuous immersion equipment.
