Requirements for materials inside and outside the explosion-proof heater industry
In the current market sales, many customers like to look at the external material (metal material) and place an order. In fact, otherwise, the inside and outside of the electric heating tube are very important. Both the explosion-proof heater industry and the heater industry are very demanding. At present, almost all electric floor heating products appearing on the market are constant-power heaters, that is, as long as there is current, they will continue to heat. If the overheating protection function of the thermostat fails, or the heat dissipation is not smooth locally, it may cause local overheating. The protection of local overheating by the thermostat is usually only detected by the ground temperature probe. It should be pointed out that for the heating cable with a diameter of 6.5 mm, whether the material of the shield layer is resistant to high temperature does not determine whether the heating cable is resistant to high temperature. The main function of the shielding layer is to protect the middle heating core wire from cutting the shielding layer and avoid short circuit. The use of TXLP or Teflon material for the shielding layer abroad does not use silicone rubber, which is also resistant to high temperatures, for safety reasons.
The same sealing material of our explosion-proof heater is mainly used to make the insulating filler not easy to absorb the moisture in the environment, and to ensure that the electric heating tube has good insulation performance. Commonly used sealing materials are paint films, such as silicone organic paint, epoxy resin, and a Base silicone oil, silicone rubber, single glass, composite glass, enamel glass, and sealing plugs made of ceramic or rubber. During the manufacturing process, pay attention to these issues. The quality of the electric heating tube can be guaranteed absolutely. Yancheng Hongtai Alloy Electric Co., Ltd. has always paid attention to the reasonable selection of these materials to ensure the quality of the internal and external materials of the product and the electric heating. The quality and life of the tube can meet the needs of customers. Electric heating tubes are divided into industrial applications and civilian applications. Through more examples and market investigations, we will find that in fact, electric heating tubes are often used more in industry than civilian applications.
It is equipped with a dedicated high-temperature low-noise fan to achieve hot air circulation heating. The light-weight suspension conveyor is used. It has the characteristics of simple structure, convenient maintenance and long service life. Using thyristor temperature control technology, LCD display working status. With voltage, current, temperature and other displays and with short-circuit, overload and over-temperature protection and alarm devices. Realize automatic control of temperature, moisture discharge and transportation. It adopts a suspension chain to move forward and out of the channel patrol loop baking oven. The oven is equipped with temperature control electric heating, and the outside of the oven is equipped with a fan to send air up and down to maintain the temperature balance at all points in the oven.
