What are the fixing methods for electrical boxes silicone rubber heaters?

Among the questions asked by many customers, the fixing method of electrical boxes silicone rubber heaters, heating films and other products is a relatively common problem. So, how to fix electrical boxes, silicone rubber heaters and other products on the heated object? The company lists several commonly used fixing methods for your reference:

1. Fix with double-sided tape.

This method is the most commonly used fixing method, that is, a layer of double-sided tape is attached to the back of the electrical boxes silicone rubber heaters (the back of the lead-out surface of the power cord). In general, double-sided tape uses high-temperature-resistant double-sided tape, such as 3M double-sided tape. If the temperature is not high, in order to save costs, ordinary double-sided tape can also be used. This fixing method is simple and easy to operate, but also has its limitations.

a. Do not reuse. Once pasted, remove the heater and the double-sided tape will lose its effect.

b. Time limitation. Generally speaking, the double-sided tape will be easily oxidized if it takes too long. As time goes by, the sticking effect will become worse.

c. The requirements for the surface of the heated object are relatively high, and the surface must be smooth, clean, and free of water droplets, etc.

d. Do not use under severe vibration conditions, because the adhesive strength of the double-sided tape itself will not be too high, especially in the case of long-term high-temperature use, the adhesive layer will be cured.

2. Reserve screw holes for fixing

This kind of fixing method is also commonly used, which is to make holes on the surface of products such as silicone heaters, silicone rubber heating plates, heating silicone sheets, and electric heating films. This method is generally flat plate heating. The holes on the heating plate and the holes on the heated object are overlapped, and then the screws are fixed. The advantage of this method is that it can be reused and can be removed when heating is not required, or replaced with other same equipment. The disadvantage is that the fit is not very tight, especially for products with a large area and few holes.

3. The spring is fixed

This method is generally used to heat the sides of cylinders, cuboids, and cubes, that is, punch holes or make iron buckles at both ends of electrical boxes silicone rubber heaters, hang springs, and hang the springs on the other end during use. Reusable and easy to disassemble. For example, the oil drum heater is fixed on the side of the oil drum with a spring for heating.

4. External fixation

That is, the heat preservation layer is covered on the outside of the heater, which not only has the heat preservation effect, but also can be fixed.

To sum up, please choose the most suitable fixing method based on the specific situation and specific analysis of the fixing method.
