The development of the heating plate is also a transformation of people's environmental consciousness
With the constant progress of science and technology, are also growing, for the consciousness of environmental protection as an example, in the past, most of the region in north China are all adopt the way of burning coal for collective heating, and now, this phenomenon has begun to change slowly, many people began to use the heating plate for heating, the heating plate is adopted to improve the heating advantage can not only save resources, also can adjust the temperature according to the actual living conditions, more convenient. And in this process, the role of heating plate is self-evident.
Now that we know the role of heating plate, what problems should we pay attention to in the process of purchasing? As we know, heating plate can be divided into three categories: unembroidered steel heating plate, ceramic heating plate, aluminum casting and copper casting heating plate, among which:
1. Ceramic heating plate: ceramic heating plate is widely used in light, heavy industry and household electric heating appliances after being electrified, and its surface is heated but not electrified. Its appearance is like the general daily porcelain, but buried in the electric heating wire, because the ceramic material used in the working temperature has a good electrical insulation performance, so the surface is not charged, the work is leakage current is small, safe and reliable use.
2, cast aluminum, cast copper heating plate, cast aluminum, cast copper heating plate manufacturers can be divided into die casting and mould casting, the specifications, the size is more occasions, generally adopts the casting process, casting production using high purity aluminum, copper pieces, by the high temperature furnace to change from solid to liquid, then the injection have been installed heating pipe mold, after cooling molding, precision work again.
3, stainless steel heating plate: mica plate, mica sheet) heater use mica plate, mica sheet) good insulation performance and its high temperature resistance, it with mica plate (sheet) for the skeleton and insulating layer, supplemented by galvanized or stainless steel plate as a support for protection, can make plate, sheet, cylindrical, conical, tubular, shapes of circle of the heater. Normal surface load of 2.5-3w, temperature tolerance of 500 ℃.
After the heating plate is electrified, it can raise the temperature to a rated stage in a very short time, and it has a considerable constant temperature effect after being equipped with the insulation device. In the process of heating, more heat is lost than effectively converted, which is a waste of resources. Therefore, we do not advocate other heating methods.
