VOC emission climate chamber is widely used in other industriesWe now know that the VOC emission climate chamber is mainly used in the home accessories industry and the automotive industry. In fact, it also plays a great role in the wool and cotton textile industry, such as: floor coverings, textiles, down, toys, and latex products. VOC emission climate chambers will be used.
Correctly understand VOC "content" and VOC "release" VOC is the English abbreviation of Volatile Organic Compounds (Volatile Organic Compounds). "VOC content" is a mass unit, which indicates the content of organic matter in the paint formula (expressed by weight); and "VOC release amount" refers to the amount of VOC released through the air during the use of the paint. The amount of organic volatile matter. The difference between the two is that VOC content does not indicate the amount of organic volatiles that can be released from the paint surface into the air.
Manufacturer: Dongguan Huanyi Instrument Technology Co., Ltd.
fulfill the standard:
GB/18587-2011 "Indoor Decoration Materials Carpets, Carpet Pads and Carpet Adhesives Release Limits of Hazardous Substances"
ISO/10580 "Resilient floor coverings, textile floor coverings and laminate floor coverings—Method for determination of release of volatile organic compounds (VOCs)"
ISO/16000-3 "Determination of formaldehyde and other carbonyl compounds in indoor air and detection cabin air - Active sampling method"
Test Methods:
1. Place the cut samples in the cabin
2. Set the temperature and humidity
3. Place it under constant temperature and humidity conditions to fully release VOC in the sample.
4. Sampling through the VOC emission climate chamber sampling products
5. Place the gas sampling tube into the automatic sampler of the thermal detachment equipment for analysis.
6. Transfer all the bubble absorption tube sample solution into the colorimetric tube, add 0.4ml ferric ammonium sulfate solution into the colorimetric tube, shake well, leave it for 15 minutes, use a 1cm cuvette at a wavelength of 630nm, and use water as a reference Ratio, measure the absorbance of the solution.
