Ceramic heating element and quartz tube heating use different places

The ceramic heating element has a slow heating speed, but has a good heat storage effect, and is more suitable for families with elderly and children at home.

Due to the small heating range of the quartz tube heater, it is suitable for a small room with an area of about 10 square meters. It generates light during heating and is not suitable for use in the bedroom.

What is PTC in ceramic heating plate?

PTC is actually a type of ceramic. The main component is lead titanate. Using internal defects caused during the firing process, the resistance value changes with temperature when the power is turned on, so that it has a relatively constant temperature under an inconstant voltage. Or to put it another way, the resistance of PTC will change with the change of voltage. Because of this feature, PTC is widely used. For example, some of the dryers used in winter, the heaters in some air conditioners, and the current-limiting electronic components used in some electronic components are also made by PTC.

Because PTC contains a large amount of lead, the lead content in the manufacturing raw materials is generally about 40%. Therefore, the use and production are now partially restricted.

Ceramic heating chip will reduce power when used for a long time?

The electric heating tube is used for a long time, and the power will be reduced if it is accurately measured. Of course, the amount of heat will also be reduced. This is because the inside of the heating tube is a heating wire. For a long time, the outside of the heating wire will be continuously consumed like a filament. The diameter will become smaller. According to the resistance formula, the diameter becomes smaller and the resistance value becomes larger. The voltage does not change and the resistance increases. So the power becomes smaller.
