How do we use the one cubic meter formaldehyde testing chamber under GB18580-2017

Formaldehyde is a colorless gas with a strong pungent odor, easily soluble in water, alcohols, and ethers. It is in a gaseous state at room temperature and is volatile (with a volatilization point of 19 ℃). The volatilization rate increases with temperature. Formaldehyde has been confirmed by the World Health Organization as a substance harmful to human health and is considered a potential carcinogen

When formaldehyde exceeds the standard, it can cause significant harm to our bodies. Generally speaking, the factors that affect the detection results of formaldehyde emissions mainly include the unevenness of the board itself, the choice of detection methods, and the influence of experimental conditions. adoptoneCubic meter formaldehyde testing chamberThe detection method is to measure 1m²The surface area sample is placed in a climate chamber with temperature, relative humidity, air flow rate, and air displacement rate controlled under specified conditions. Volatile organic compounds (formaldehyde) are released from the sample and mixed with the air inside the box. The air inside the box is collected, and the formaldehyde concentration in the air is tested to calculate the formaldehyde release rate of the sample. oneCubic meter formaldehyde testing chamberExtraction is periodic until the formaldehyde concentration in the air inside the climate chamber reaches a stable state. Due to the rounded treatment of each corner of the box, formaldehyde is not adsorbed or released. The sealing ring adopts imported formaldehyde free sealing strips to ensure the isolation of the test box from the external environment, resulting in more accurate calculation results.
