Electrical insulation material

Mainly used for motors, electrical appliances, such as in the generator, the motor for the armature wedge, stator windings, rotor winding insulation. According to the shape is divided into six categories: ① insulating paint, resin and adhesive category. For example, insulating impregnated paint, silicon steel lacquer, enameled wire paint, potting resin and a variety of adhesives and other commonly used epoxy resin, polyimide glass fiber, polyurethane, silicone resin, polyimide alkyd resin (see alkyd paint )Wait. ② impregnated fiber products. Such as resin impregnated with various types of cotton, silk, synthetic fiber and glass fiber or fabric insulation fabric, belt and other products. ③ laminated products category. Various organic or inorganic substrates are impregnated with resin after laminates, such as laminates. ④ plastic products category. From the resin to add a variety of organic or inorganic filler, such as TV shell, instrument, instrument shell, electrical switch connector shell and so on. ⑤ thin film, synthetic paper and its composite products category. For example, various polymer film dielectric materials, commonly used are polystyrene, polypropylene, polyester, polycarbonate, polytetrafluoroethylene, polyimide and other films; various synthetic fiber insulation paper, such as aromatic poly Amide fiber paper, polyester fiber paper; all kinds of insulating adhesive tape, insulation tape, and so on. ⑥ rubber products category. Such as a variety of wire and cable insulation and jacket, heat shrink tubing, silicone rubber insulation terminals.

Electronic insulating material

Mainly used for semiconductor components and electronic equipment, insulation protection. ① printed circuit board, that is, copper-coated version. Substrate for the resin laminated compressed wood, known as rigid copper clad version, often used epoxy, phenolic and other resin plate; substrate for the polymer film or single layer of heat-resistant glass cloth, said the flexible copper-clad version, Often used polyester, polyimide, fluoropolymer film. ② packaging materials used to prevent the outside world moisture and impurities on the impact of semiconductor components parameters. At present, about 90% of the semiconductor components used in plastic packaging. Mainly with epoxy resin and silicone resin, followed by phenolic resin, polyester, polybutadiene and so on. (3) Insulating film for semiconductor devices, a surface protective film (including a contact film, a passivation film, a moisture-proof shock film, an α-ray shielding film for preventing soft errors, etc.) of a semiconductor element such as a large-scale film integrated circuit, and an interlayer insulating film The Such as polyimide-based aromatic heterocyclic polymer.

mica tape for cable environmental protection plastic products, after burning odorless and tasteless, does not produce toxic gases, transparent, surface water ripples, no crystal point, no double phase fold white, resistant to grease and chemical strong, toughness and rigidity, impact resistance Good strength (low temperature impact resistance is also good, 20% higher than the PVC standard), for blister, folding boxes, packaging, printing, printing and so on. Transparent film used Transparent PET film for electronic, printing, packaging, insulation, flexible line printing, display screensaver PET, membrane switch, film window, printing film, make-up film base, stickers at the end of paper, Motor gasket, GPO3 sheet belt, instrument panel, capacitor insulation, furniture stripping, window film, protective film inkjet printing and decoration, etc.

mica insulation sheets sericite has a good chemical stability, mica particles fine, Naisuan Jian, anti-aging, the UV has a better shielding function. After the wet purification, the whiteness, hiding power, gloss, creamy feeling, dispersion, adhesion and so have a greater increase, with water, glycerol evenly mixed, and the texture of the rich and flexible, is a senior beauty cosmetics Of the first choice of raw materials and cosmetics foundation materials, can be used as emulsion, cream, pearl agent until the ingredients.
Natural mica gasket is a thick insulation material tube after stripping, thick, cut, drilling or punching, with a certain thickness, a certain shape of the mica parts, the product is suitable for televisions, power capacitors, thermal relays, monitoring Display, aerospace, aviation, communications, radar, heat-resistant matrix tablets as raw and auxiliary materials. It is a kind of natural mineral products, which has the characteristics of no pollution, insulation and voltage resistance. It can be cut according to customer's needs. Of natural mica gaskets.

Insulation sleeve is a kind of mica insulation sheets, is a collectively. The insulation sleeve is made of high quality muscovite paper or phlogopite paper with high-performance organic silica gel bonded by the processing of the rigid tubular insulation material. Insulation casing (mica casing) has good electrical insulation performance and high mechanical strength, insulation casing (mica casing) cooperation in a variety of electrical appliances, electrical, electric smelting furnace and other equipment in the electrode rod or outlet mica casing insulation. Compared with the traditional ceramic tube, insulation casing (mica casing) with wall thickness and oval degree easy to control, discharge evenly, not broken, etc., polyimide glass fiber(mica casing) is the ideal alternative to some ceramic tube. Insulation sleeve (mica casing) is divided into hp5 mica tube temperature 500 ℃, hp8 gold mica tube temperature 800 ℃.

insulation cable paper has inherent dielectric strength, mechanical toughness, thermal stability, chemical compatibility, low temperature performance, is not sensitive to moisture, radiation resistance is the specific characteristics of insulating paper, and we in the future work or life You can use it, you can use it for dry-type transformer circuit breaker panel, spiral wound tube, capacitor insulation layer, DC coil insulation, current-carrying wire and devices, busbar insulation and other aspects, these aspects are Can be used very well, can make the insulating paper play a very good role.
Insulation paper, whether it is for us to work or life, then, is a very good thing, to our lives has brought a lot of help to improve our work efficiency

bakelite electrical insulation board, in recent years, made a special high temperature paper manufacturing breakthroughs, there are several enterprises producing insulating paper products, the temperature and pressure resistance, and the current foreign commonly used H-class insulation paper performance close to the insulation level are To 200, Mu H-class magnet wire requirements. At present, in a company's newly developed mine explosion-proof dry-type transformers, made a domestic insulation paper trial and verification.
In order to improve the production efficiency and working quality of insulating paper embedded in the rotor slot of the motor, it is necessary to conceive a high efficiency motor rotor embedded paper machine.
The working process of the rotor of the motor rotor
The g10 fiberglass sheet is fed to the working platform through the stick, the cutter moves down, cuts the insulating paper, and returns it. The insulating paper continues to move forward in the next cycle, the paper feed machine moves down and returns, The paper is sent to the tank, the motor rotor turns sixty degrees, pushing the paper machine down and pushing the paper into the slot
