Paint thinner is a kind of used to dilute the paint mixed organic solvent, also known as the paint thinners or solvent oil; Auxiliary materials are widely used in wood surface decoration. Early paint thinner varieties mainly include turpentine, banana oil and water, that day which contains a large quantities of benzene, with the improved paint production technology, the requirements of environmental protection, labor health and occupational safety, to protect the paint, professional construction personnel
xiangying eagle analysis technology co., LTD. Established XingyingGC7990olus gas chromatography in the paint thinner, benzene, toluene, ethyl benzene, xylene isomers variety of poisonous and harmful ingredients detection technology at the same time. Separation by HP - 5 quartz capillary column and FID detector, a chlorinated benzene as internal standard, investigates the main benzene series of linear correction factor and recovery situation. Results: the linear regression in good condition, correlation coefficient r in addition to the benzene 0.99; (to) between benzene, toluene, ethyl benzene, xylene, o-xylene average relative correction factor were 0.6229, 0.6994, 0.7347, 0.7230, 0.7320; Recovery rate were 98.57%, 97.69%, 95.92%, 97.41%, 95.92%. Total two no benzene, thinner, benzene content, respectively, 50.98%, 49.88%, and contains trace benzene; Rosin water benzene, benzene content 12.93% 6.77%, no benzene toxicity than thinner.
油漆稀释剂是一种用于稀释油漆的混合有机溶剂,又称为油漆稀料或溶剂油;广泛应用于木材表面装饰辅助材料。早期的油漆稀释剂品种主要有松节油、香蕉水和天那水,其中含有较大量的苯,随着油漆生产技术的改良、环境保护的要求、以及劳动卫生职业安全,切实保护油漆施工人员的职业
滕州市翔鹰分析技术有限公司建立了XingyingGC7990olus气相色谱法油漆稀释剂中苯、甲苯、乙苯、二甲苯异构体多种有毒有害成分同时检测技术。采用HP-5石英毛细管柱分离,FID检测器,一氯代苯作为内标,考察了主要苯系物的线性,校正因子和回收率情况。结果:线性回归情况良好,相关系数r除苯以外均0.99;苯、甲苯、乙苯、间(对)二甲苯、邻二甲苯的平均相对校正因子分别为0.6229、0.6994、0.7347、0.7230、0.7320;回收率分别为98.57%、97.69%、95.92%、97.41%、94.19%。两种无苯稀释剂苯系物总量分别为:50.98%、49.88%,含有微量苯;松香水中苯含量为6.77%、苯系物总量12.93%,毒性大于无苯稀释剂。
