摘要
采用手动喷雾器将试剂喷入染毒柜中,用量为6.25mL/m^2。观察不同时间段甲醛浓度的变化情况,甲醛净化率,重复3次,且选择其他两种空气净化剂(A、B)进行对比。结果表明在不同时间段中,使用氧泡泡空气净化剂后,甲醛的含量有所不同,其中在40 min时,甲醛含量已经为0。可见采用氧泡泡空气净化剂清除甲醛在40min后可完全清除。不同净化剂对比上,氧泡泡的除甲醛率为90.5%,净化剂A的除甲醛率为68.0%,净化剂B的除甲醛率为80.1%,可见氧泡泡空气净化剂的除甲醛率相对最好。应用氧泡泡空气净化剂除甲醛可起到较好作用,去除率较高,安全性也较高,值得应用。
A manual sprayer is used to spray the reagent into the exposure cabinet, and the dosage is 6.25mL/m^2. To observe the change of formaldehyde concentration in different periods, the formaldehyde purification rate was repeated three times, and the other two air purifiers （A, B） were compared. The results showed that the content of formaldehyde was different after using oxygen bubble air purifier in different time periods, and the content of formaldehyde was already 0 at 400 min. It can be seen that the use of oxygen bubble air purifier to remove formaldehyde can be completely removed after 40min. Compared with different purifiers, the formaldehyde removal rate of oxygen bubble was 90.5%, that of purifier A was 68.0%, that of purifier B was 80.1%, and that of oxygen bubble air purifier was the best. The application of oxygen bubble air purifier to remove formaldehyde can play a better role, the removal rate is higher, the safety is also higher, it is worthy of application.
