The printing industry emits a large amount of volatile organic compounds, and the environmental impact cannot be ignored. At present, the national printing industry volatile organic matter emission standards have not been promulgated and implemented, and there are significant differences in the monitoring and evaluation indicators of VOCs emission levels by various local standards, including total volatile organic compounds (TVOCs). ) and non-methane total hydrocarbons (NMHCs) two categories.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. compares the definition and analysis methods of TVOCs and NMHCs, and analyzes the numerical difference between NMHCs and TVOCs in the exhaust industry of printing industry through on-site sampling and experimental tests. The research results show that Under the conditions, in the typical volatile organic compounds test and on-site sampling test in the printing industry, the detection values of TVOCs are larger than NMHCs. The possible reasons are the specificity of volatile organic compounds emitted by the printing industry, and the reference materials selected in the calculation of the two are different. And the sensitivity of the detector is different. based on the above research results, from the perspective of effective supervision in the long run, the printing industry standard adopts TVOCs as the control index is relatively scientific and reasonable.
