Silicone rubber is a new type of polymer elastic material, has excellent high temperature resistance (250-300℃) and low temperature resistance (-40-60℃), has excellent resilience and small permanent deformation characteristics.Special silicone rubber also has oil resistance.

  In terms of electrical performance: even the silica generated by short-circuit combustion is still an insulator, which ensures that the electrical equipment continues to work.

  Surface properties: non - stick to many materials, can play an isolation role. It is because of the many excellent properties of silicone rubber that it is widely used.It is composed of power line, silicone rubber layer, heating resistance wire, heat insulation layer, silicone rubber insulation layer and aluminum plate.

  Working principle: Wrap fixed power resistance wire circle in the silicone rubber, which can generate heat after the power supply, and the existence of heat insulation, insulation, make the most of the heat generated by the resistance wire in the direction of the panel, sulfide or bonded aluminum plate on the back of a silicone rubber layer is setting the base board, and excellent heat conductor, and environmental temperature balance quickly, not surface temperature is too high, This protects the mounting surface from high temperatures and creates holes that can be fixed to the wellhead box wall.

  After the installation of electricity, the non-contact infrared thermometer is used to measure the temperature of the heating surface of the heating plate, the wire joint, the wellhead box wall and the ambient temperature.The following experimental data were obtained:

  By looking from summer to winter temperature test for a long time, at different times, different weather conditions, through the sunlight, wind blowing rain, water and gas purging invasion experiment under the test temperature, the heating plate has a good stability and the normal work of the positive temperature between 110 ~ 165 ℃, and the back temperature in 45 ~ 65 ℃, no is not hot, such as high temperature condition, It is proved that the electric heating plate has good stability.

  Through the above simulation tests, we see that the electric heating plate has a good operation stability;High insulation effect;It has certain mechanical damage resistance and reliable security, and can be used in oil fields.With the leapfrog growth of consumption, silicone rubber industry has made remarkable achievements.Silicone rubber industry has begun to transform from high-performance special rubber to public synthetic rubber, becoming one of the rubber varieties with a large amount of Z.It is reported that from the rubber consumption of rubber types, natural rubber accounted for 41.8%, styrene butadiene rubber and butadiene rubber combined accounted for 28.4%, and silicone rubber is usually only used for building sealant, conductive buttons and a few non-tire areas, only accounted for 6.4% of the total rubber consumption.Therefore, as silicone rubber replaces other rubber varieties in some non-tire segments, its consumption will increase exponentially and the market space will be further opened.To this, the personage inside course of study also agrees above viewpoint.It is expected that by 2015, silicone rubber will account for 10% ~ 15% of the total domestic rubber consumption, that is, silicone rubber consumption is expected to reach 1 million ~ 1.5 million tons, and by 2020, silicone rubber is expected to account for 20% ~ 33% of the total rubber consumption, that is, silicone rubber consumption is expected to reach 3 million ~ 5 million tons.In other words, the development potential and long-term development of the silicone rubber industry are very attractive, and its rapid development will also have a profound impact on the upstream and downstream industries.In fact, the linkage effect of upstream and downstream industries in silicone rubber industry has begun to emerge gradually.Some experts point out that the Z bright spot of silicone rubber industry development is that it can greatly improve the domestic self-sufficiency rate of rubber.According to statistics, if the proportion of silicone rubber in China's rubber consumption is increased from 6.5% to 33% by 2020, the overall domestic self-sufficiency rate of Rubber in China can be increased from about 50% to more than 80%, thus greatly relieving the tight rubber supply and reducing the production cost of rubber processing industry.It can be seen that the development of silicone rubber industry is not only a single development of a single industry, but also involves the common development of multiple industries, which has far-reaching significance for enhancing the profitability of rubber processing industry and improving the quality level of rubber products.
