Heating principle of silicone heater
The silicone rubber heater is mainly composed of a nickel-chromium alloy heating wire and a high-temperature insulating layer of silicone rubber. Silicone rubber high temperature insulation layer is a lamella (composite thickness of 1.5mm) made of silicone rubber and glass fiber cloth. Silicone rubber heater has good flexibility; it has fast heating, uniform temperature, high thermal efficiency and high strength. Easy to use, safe and long lasting for four years, not easy to age. Commonly known as silicone heating sheet, silicone rubber heating film, silicone rubber heating sheet, etc., silicone rubber oil drum heater.
The insulating layer of the silicone rubber heater is a sheet-like composite of a silicone rubber and a glass fiber cloth (standard thickness is 1.5 mm). The silicone heating sheet has good flexibility and can be in close contact with the object to be heated; The alloy foil of nickel alloy is processed, the heating power can reach 1.2W/CM2, and the heating is more uniform. This way, heat can be transferred to wherever it is needed.
Silicone rubber heaters are used at temperatures ranging from -60 ° C to 250 ° C. The voltage can be customized according to user requirements, the highest power density is 2.1W/cm2. The heating core has two kinds of high electric heating wire and metal film. The electric heating core made of the film can make the heater with high power density and has excellent rapid heating function.
The silicone rubber heater is in the form of a sheet which has excellent flexibility and can be in full contact with the object to be heated. In this way, heat can be transferred to where it is needed.
Features:
(1) Various shapes and sizes can be customized according to customer requirements.
(2) The insulating layer of silicone rubber heater is made of silicone rubber and glass fiber cloth. It has high insulation performance and the breakdown voltage can reach 20~50KV/mm, so it is completely safe to use.
