Common Problems In the Use of Heating Sheet

1.What is the difference between 110V and 220V PTC Heating Sheet ? What happens when 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 . Need advised to use it as a match .

2. 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 , and the vortex magnetic field generates a vortex current in the silicone heating sheet , and the 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 .

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 .

4.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 , and no strong light can be seen , and it will not hurt .

5.The advantages of various types of heating tablets are not the same, 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 tablets
The infrared radiation is strong when the component works , 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 , long service life , it has obvious characteristics such as large bending strength and heat shock strength, can closely fit various circular surfaces to greatly enhance thermal efficiency .
（5）The best waterproof and moisture-proof heating sheet - non-woven heating sheet
