What are the common insulation materials? I searched the Internet and found that there are countless stories about this topic. But most are not very comprehensive, and the description is not very detailed. This is very troublesome for many friends who are entering the industry. Just today I have time. Zhongtian Electric Equipment Group, as a professional manufacturer of insulating materials, gives a detailed explanation of the above questions.
In general, insulation materials are divided into electric and non-electrical. Electrical insulating materials generally include epoxy and electric wood; non-electrical insulating materials include acrylic, synthetic, carbon fiber, and the like. Today I will make a detailed analysis of these two aspects.
First look at electrical insulation materials:
epoxy board according to the performance of the board can be 3240, FR-4, G11 and other models. The performance characteristics of these three models have an increasing relationship. The 3240 epoxy board is the most basic board. It is the only material that is not very environmentally friendly and is halogen. However, its price is very cheap, and it is used in many electrical and electronic industries where performance requirements are not very high. So there is still a certain market. The performance of FR-4 epoxy board is outstanding, whether it is insulation, dielectric or high temperature resistance, easy processing and so on. It is currently the material of choice for many high-end electrical and electronic insulation components. As for the G11 epoxy board, its performance is the most prominent one of the current oxygen-alkali plates. It has a high temperature resistance of up to 160 degrees and a tension of 288 degrees. It is the latest type of sheet. Used in many aviation, aircraft carriers and other fields.
There are many names for bakelite, some are called bakelite, and some are called phenolic resin laminates. A phenolic laminated paperboard formed by hot pressing of bleached wood pulp paper with phenolic resin. This product is suitable for use as insulation structural parts in motors and electrical equipment with high mechanical performance requirements, and can be used in transformer oil. It can withstand temperatures up to 300 degrees in a short period of time and up to 140 degrees in long periods of time. This will undoubtedly allow the bakelite to prolong life.
Next, look at non-electrical insulation materials:
crylic is the most common material in everyday life. Such as coffee tables, shop windows, showcases, lampshades, floors, and so on. In fact, it is a special kind of plexiglass, but it has a good non-fragile and soft texture compared to plexiglass. And its light transmission is as high as 92%, which greatly saves energy. In addition, it has good weather resistance, light weight and easy to clean.
Synthetic stone is not only the best material for paving the countertops, bathroom floors, hospital floors, etc. It can also be used in the field of industrial SMT wave soldering. It is used for laying on the ground because it is a synthetic polymer compound. It has large-area laying without chromatic aberration, anti-penetration, easy to clean, rich in color, and no radiation. In line with the environmental awareness of modern people. The synthetic stone used in the industrial field has a working temperature of 260 ° C and a maximum working temperature of 350 ° C to 400 ° C. And the production of high temperature resistance 350 degrees without deformation, small expansion, suction furnace oil.
