What are the requirements for using 1 cubic meter of formaldehyde to test the climate chamber

Formaldehyde detection climate chambers are generally used in scientific research fields such as bioengineering, medicine, forestry, environmental science, building decoration, automobile interiors, furniture decoration, daily necessities, plastic materials, etc. Do you know what its requirements are? Today, I will explain to you what are the requirements for using 1 cubic meter of formaldehyde to test the climate chamber.

1. Airtightness

The formaldehyde detector climate chamber should simulate the indoor environment, not a completely closed system. The air in the box needs to be dynamically exchanged. The test standard stipulates that a slight positive pressure is formed in the box by injecting clean air to ensure that no uncleaned air enters, which affects the accuracy of the test results.

3. Noise index

This requirement is related to the operating noise of the refrigeration compressor in the equipment. In order to meet the requirements of the national urban area noise standard (GB3096-93), the operating noise of the formaldehyde detection climate chamber is specified as 70dB. After the wall of the laboratory is blocked, the actual measurement results show that the outdoor noise is lower than my country's regulations on the two standards applicable to residential, commercial, and industrial mixed areas (this index has no effect on the completion of equipment testing).

3. Thermal insulation regulations

It is necessary to ensure that the formaldehyde detection climate box has a good thermal insulation effect to reduce unnecessary cold and heat exchange inside and outside the box and save energy consumption. At the same time, it can prevent condensation on the inner surface of the box and absorb formic acid, resulting in deviations in the test results.

4. Requirements for the internal facilities of the climate chamber because formic acid is easily soluble in water

No condensation should occur in any part of the climate box. If a temperature and humidity control compressor is used, the refrigeration coil is not allowed to be installed in the box. To prevent the humid air from condensing water on it, which will affect the authenticity of the test results. This is clearly stated in similar standards in the United States.

The above points are the requirements for the use of 1 cubic meter of formaldehyde to detect the climate chamber. my country has used the formaldehyde climate chamber to detect the formaldehyde emission of wood-based panel products for more than 10 years of practice and exploration. In terms of R&D and manufacturing of reliability testing equipment, our company also has 15 years of experience. Our company specializes in the production of voc and formaldehyde testing equipment. The products have won a good reputation among the peers with excellent quality and favorable prices. The products are exported to foreign countries and have a good reputation at home and abroad.
