1.The advantages of various types of heating tablets are different, how to distinguish?
（1）The safest heating sheet - usb heating sheet, polyester heating sheet
Surface safety no electricity, good insulation performance, no open flame, safe use
（2）The softest heating sheet - silicone heating sheet
It has good softness and can be in complete close contact with the heated object. Because it is flexible, it is easier to get close to the heating body, and the shape can be designed to change with the requirements of the heating, so that the heat can be transferred to any place where it is needed
（3）The most healthy heating tablets - mica heating tablets, polyester heating sheet
The infrared radiation is strong when the component works, and its far-infrared wavelength is 2-15um, which is beneficial to human health
（4）Heat shock heating sheet - arc heating sheet
In addition to the advantages of rapid heating of plate heating elements, high thermal efficiency, uniform heating, no open flame, safety and environmental protection, and long service life, it has obvious characteristics such as large bending strength and heat shock strength, and can closely fit various circular surfaces to greatly enhance thermal efficiency.
（5）The best waterproof and moisture-proof heating sheet - non-woven heating sheet
2.Will PTC heating tablets explode?
PTC Heating Sheet has a failure mode called breakdown , breakdown when the popping sound accompanied by strong light.
Under normal circumstances, the PTC Heating Sheet will have an external insulation structure, there will be a small popping sound when the breakdown occurs , no strong light can be seen, it will not hurt .
3.How to assemble 5-head PTC Heating Sheet ?
5 head PTC Heating Sheet should be connected according to different power needs , 1, 3, 5 is a pole; 2, 4 is a pole, 1, 3, 5 and together as one end; 2, 4 and together for the other end, access to 220V is full power.
5.What is the difference between 5.110V and 220V ptc heating tablets? What happens when you mix it?
PTC Heating Sheet is a device with positive temperature coefficient , the resistance value increases greatly with the increase of temperature. If the 220V heating sheet is used on 110, the resistance increase is relatively small , current will be relatively large , but the heat will not necessarily increase a lot. You are advised to use it as a match.
6. How to install silicone heating sheet ? Can I use DC power?
When the silicone heating sheet is used, it can be installed by various methods such as double-sided adhesive, room temperature vulcanization, drilling and positioning according to the actual site. Silicone heating sheet can not use DC power supply.
The heating principle of the silicone heating sheet is that , the alternating current generates a vortex magnetic field in the silicone heating sheet , vortex magnetic field generates a vortex current in the silicone heating sheet , silicone heating sheet has large resistance.
So the vortex current is converted into heat , if the use of direct current , silicone heating sheet will not have vortex current, can not produce heat .
