Moisture-proof insulating plastic

Insulation sheet is in various forms. A variety of resins, curing agents, and modifier systems can be adapted to suit the requirements of various applications, ranging from very low viscosity to high melting point solids. Easy to cure. With a variety of different curing agents, the epoxy resin system can be cured in the temperature range of 0-180°C. Strong adhesion. The presence of polar hydroxyl [1] groups and ether bonds inherent in the epoxy resin molecular chain gives it high adhesion to various substances. The shrinkage of the epoxy resin when cured is low and the resulting internal stress is small, which also helps to increase the adhesive strength.

Low shrinkage. The reaction of the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization of epoxy groups in the resin molecules, without the release of water or other volatile by-products. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage (less than 2%) during curing. Mechanical properties. The cured epoxy resin system has excellent mechanical properties. Insulated glass fiber cloth is bonded with epoxy resin and heated and pressed. It has high mechanical properties under medium temperature and stable electrical properties at high temperatures. Suitable for high insulation structural parts used in machinery, electrical appliances and electronics, with high mechanical and dielectric properties, and good heat resistance and moisture resistance.

It is made of adhesive insulating material, and there should be no harmful irregularities on the upper and lower surfaces of the insulating pad. The harmful irregularity of the insulating mat refers to one of the following characteristics, namely the defects that destroy the uniformity and damage the smooth surface of the surface, such as holes, cracks, local bulges, incisions, inclusions of conductive foreign bodies, creases, voids, bumps, and castings. Signs, etc. Harmless irregularity refers to the measurement of surface irregularities formed during the production process. The accuracy of the micrometer shall be within 0.02mm, the diameter of the drill shall be 6mm, the diameter of the flat presser foot shall be (3.17±0.25)mm, and the presser foot shall be able to apply a pressure of (0.83±0.03)N. The insulating mat shall be laid flat to Make the micrometer measurement smooth.

The storage of goods can play a role in preventing moisture. Plastics are also divided into general-purpose plastics and engineering plastics, which are mainly defined by the versatility of use. For example, PE and PP are inexpensive and can be produced on various types of machines. Engineering plastics are more expensive, but the stability of raw materials and physical properties are much better. In general, they have both rigid and tough properties. PVC transparent plastic plate: A high-strength, high-transparent plastic plate produced by the introduction of foreign advanced technology and high-grade imported raw and auxiliary materials.
