Musical Instruments, wood products, furniture, flooring, carpet, footwear products, building decoration materials, automotive interior and other materials in contact with human body will volatilize VOC (volatile organic compounds), formaldehyde and other harmful substances to human health.
This test chamber is a kind of instrument and equipment used to simulate the release of VOC (formaldehyde) in the environment close to people's living. It is used to test the amount of harmful substances released in furniture, Musical Instruments, building materials, automobile interior decoration and other products.
The test chamber provides a clean enclosed space to control the temperature, humidity, wind speed, relative pressure and air exchange rate in the chamber, which is used to simulate the pollutant release process of the product in a specific environment. The pollutant concentration in the chamber is monitored to determine the release amount, which is used to evaluate the environmental protection level of the product.

From the outside to the inside, the test chamber consists of the insulation shell of the storage board, the air jacket, the work bin and the equipment bin.
1) Library board insulation shell: the surface is 0.8mm high-strength color steel plate, the middle is filled with high-density polyurethane insulation material, thickness100mm; Surface treatment: electrostatic spraying. Good insulation can prevent energy loss in the test chamber and isolate the environment
The influence of the working bin to ensure the stable operation of the equipment.
2) Air sleeve: It is a sealed space formed between the shell and the working bin, which is equivalent to the working bin being wrapped by a layer of air, through control
The temperature of the air in the sandwich is used to indirect the temperature in the working chamber.
3) Working bin: Made of inert and smooth mirror stainless steel with full welding, good sealing, smooth and non-absorbing inner wall
Attached organic matter. At the same time, clean materials such as expanded polytetrafluoroethylene are carefully selected for sealing, and micro positive pressure inside the cabin is maintained to prevent the outside world
The entry of pollution.
4) Equipment warehouse: used to place the monitoring device, temperature control device, humidity control device, air supply components, filtration and purification of the equipment
A system, electrical device, etc.
