1: How to deal with the damage of silica gel heating plate?
Need to check the extent of damage, such as the damage area is not large, just a small hole, can be repaired in use.
2: Can the heater be used in water?
Silica gel heating plate can not be directly immersed in water (except for special waterproof heating plate).
3: Can the heating plate be cut freely?
The heating plate after manufacturing cannot be cut.
4: Power density of heating element.
In various applications, 0.6-0.8w/cm2 is the most common power density.
