摘要
在二甲基亚砜中浸渍1-(2-甲氧基苯基)哌嗪的聚氨酯泡沫海绵安装在盒式和可吸入式有机监测采样器中,然后与双过滤盒式进行比较。在实际喷漆操作中,样品用于收集六亚甲基二异氰酸酯(HDI)单体和低聚物。双滤盒放置在人体模型上。将聚氨酯泡沫盒(PUF CAS)和聚氨酯泡沫可吸入有机监测仪(PUF IOM)采样器放置在相同的最大过喷区域的手推车上。本中试研究的数据表明,与双滤盒相比,PUF IOM取样器获得的HDI单体数量没有显著差异(P < 0.05, n = 6)。数据还表明,PUF IOM取样器比双滤盒或PUF CAS取样器产生更多的HDI低聚物,两者之间均没有显着差异(P < 0.05, n = 6)。
A comparison of solid sampler methods for the determination of hexamethylene-based isocyanates in spray-painting operations.
A polyurethane foam sponge impregnated with 1-(2-methoxyphenyl) piperazine in dimethylsulfoxide was mounted in both cassette and inhalable organic monitor samplers and these were then compared with a dual-filter cassette. The samplers were used for the collection of hexamethylene diisocyanate (HDI) monomer and oligomers during actual spray-painting operations. The dual filter cassettes were positioned on a mannequin. The polyurethane foam cassette (PUF CAS) and polyurethane foam inhalable organic monitor (PUF IOM) samplers were positioned on a cart in the same maximum overspray area. Data from this pilot study suggest that there is no significant difference (P < 0.05, n = 6) in the amount of HDI monomer obtained with the PUF IOM sampler when compared with the amount obtained from the dual filter cassette. The data also suggest that the PUF IOM sampler yields a higher amount of HDI oligomer than either the dual filter cassette or the PUF CAS sampler, neither of which exhibited a significant difference (P < 0.05, n = 6) from each other.
