VOC Pretreatment Room
Product purpose
Pretreatment room can provide standard temp.,humidity and voc clean environment.After temp. humidity,pressure and voc of testing materials are released in balance,pollutant release rate and release properties of material and products will be tested.
Principles
Place materials and products or their samples in the pretreatment room, and adjust indoor temperature,relative humidity,wind speed,pressure,indoor voc cleanliness conditions and other environmental conditions,so that temperature and humidity of test samples can reach consensus,and internal and external pressure of them in balance.Meanwhile,crossed contamination of test samples should be avoided (crossed contamination of TVOC release and crossed contamination of single unit VOC)
Range of temp. and humidity:
22℃~25℃±2.0℃(adjustable temperature)
45~50%R.H.±5%,wind speed under 0.3m/s
VOCS is required to be air intake volatility.
Organic concentration should nor exceed the following indexes

Note:
1. No pollutant source in the surrounding environment.
2. Power:AC380V 20KW(this power is set for one set of machine unit,and general power shall accumulate if the inner volume is relatively big and 2 or 3 machine units are adopted.)
