1. The inner wall of the constant temperature and humidity test chamber should be made of materials with heat resistance, corrosion resistance and certain mechanical strength, and there should be no pollution sources that affect the test. Coors environmental testing technology The inner wall of the constant temperature and humidity test box is made of SUS304 stainless steel, which meets the above requirements.
2. Thermal insulation materials should be high temperature resistant and flame retardant. The thermal insulation material of Coors environmental testing technology is superfine glass fiber brocade.
3. The thickness of the insulation layer shall ensure that the temperature of the accessible part outside the test box is not higher than the ambient temperature of -35℃. The thickness of internal and external walls of thermal insulation layer in our company is 80mm/ 100mm.
4. The heating device should not directly radiate the sample. Coors Environmental Testing Technology The heating device of the constant temperature and humidity test chamber is located at the back of the studio, which adopts a completely independent system and a nickel-chromium alloy electric heater.
5, constant temperature and humidity test box should be equipped with lead holes.
6. The sealing performance of the door should be good, and the sealing strip should be resistant to high temperature and easy to replace. Coors adopts double-layer high-temperature and aging-resistant silicone rubber door seal, which has excellent heat insulation effect.
7. There should be a sample rack to place or hang the test samples. The sample rack should have good heat resistance, oxidation resistance and corrosion resistance. Two layers of sample racks are standard, which can be added according to customer requirements.
8, constant temperature and humidity test box appearance coating should be smooth, uniform color. There shall be no exposed bottom, blistering, delamination or scratches.
After mastering the above eight requirements, you can basically choose a better outer box of constant temperature and humidity test box. Of course, we also know that we should not only close the box when choosing, but also pay attention to the subsequent maintenance work. Only by effectively combining the two sides can the life and quality of the constant temperature and humidity test chamber be more effectively guaranteed.
