Formaldehyde VOC pre-treatment chamber is a device used for pre-treatment of materials such as artificial boards to determine their formaldehyde or VOC emissions. It simulates real environmental conditions to detect the VOC emissions of materials or products in specific environments, or to purify the air.
Working principle: Place the material sample in the pre-processing chamber, and adjust the environmental conditions such as temperature, relative humidity, wind speed, and pressure inside the chamber to achieve consistent temperature and humidity. This ensures that the release amount and rate of the sample reach equilibrium while avoiding cross contamination between the samples.
Structural composition: usually composed of cabin, temperature and humidity control system, air circulation system, gas purification system, etc. The cabin is generally made of materials such as stainless steel, which has good sealing and corrosion resistance; The temperature and humidity control system can accurately control the temperature and humidity inside the cabin; The air circulation system ensures even distribution of temperature and humidity inside the cabin; The gas purification system is used to reduce the background concentration inside the cabin and avoid interference with the sample.
Product features: It has the characteristics of low background concentration and high air exchange rate, which can effectively avoid cross contamination and interference between samples. Meanwhile, adopting intelligent design, the operation is simple and convenient, energy-saving and environmentally friendly during operation, and safe and reliable.
function
Removing harmful gases: Air purification technologies such as activated carbon adsorption, photocatalyst, negative ion generation, and catalytic decomposition are used to effectively remove harmful substances such as formaldehyde and VOCs from the air, improving air quality.
Simulate real environment: By accurately controlling parameters such as temperature, humidity, airflow velocity, and air displacement rate, simulate indoor or specific usage environments to provide a standardized testing environment for VOC emission detection of materials or products.
Detection of VOC emissions: Used to detect the release of harmful substances such as formaldehyde, benzene, TVOC, etc. in building materials, furniture, automotive interiors, electronic devices, etc., to ensure that the product meets environmental standards.
Avoiding cross contamination: In the formaldehyde VOC pretreatment balance test chamber, a multi chamber configuration can achieve simultaneous pretreatment of multiple samples without cross contamination, improving experimental accuracy and efficiency.
Application areas: Widely used in industries such as building materials, furniture, textiles, and automobiles, suitable for measuring formaldehyde emissions from various indoor decoration materials such as artificial boards, composite wooden floors, carpets, coatings, etc. It can also be used for constant temperature and humidity balance treatment of wood or artificial boards.
