Discussion on the influencing factors for determination of formaldehyde emission in rock wool by gas analysis
In this paper,the factors affecting the determination of formaldehyde emission in rock wool by gas analysis are studied,including the background of the test chamber,the replacement of bottle washing water,the effectiveness of silica gel and the airtightness of the gas supply system.The results show that in the state where the formaldehyde content in the bottle washing water is not saturated,the background of the test chamber and the replacement of the bottle washing water have no significant impact on the test results.The effectiveness of silica gel and the airtightness of the gas supply system have a significant impact on the test data.Among them,the airtightness of the gas supply system also has a significant impact on the effectiveness of silica gel,and has the greatest impact on the test results.
