【摘要】：为改善固体消毒剂的流散性以及对芥子气模拟剂2-氯乙基乙基硫醚(2-CEES)的消毒能力,以环境友好的过氧化物单过氧邻苯二甲酸镁(MMPP)为芯材,以不同吸附材料为壁材,通过流化床包衣技术,制备了新型芯-壳结构复合消毒粉MgO/MMPP,Al_2O_3/MMPP,活性白土(HEAC)/MMPP,并以羟丙基甲基纤维素(HPMC)/MMPP为对照研究了复合消毒粉微观形貌、粒径、流散性能、稳定性和2-CEES的消毒能力等性质。结果表明,复合消毒粉在提高MMPP流散性的同时,表现出良好的热稳定性,且消毒能力有了较大提高,其中MgO/MMPP,Al_2O_3/MMPP对2-CEES的消毒率高于99%,反应产物主要为2-氯乙基乙基亚砜和2-氯乙基乙基砜。通过流化床制备的复合消毒粉比MMPP有更好的消毒能力,这为新型吸附反应型洗消剂的开发提供了技术支撑。
[Abstract]:In order to improve the dispersibility of solid disinfectant and the disinfection ability of mustard gas mimic agent 2-chloroethyl thioether (2-CEESs), the environmentally friendly magnesium peroxyphthalate (MMPP) was used as the core material and the different adsorbed materials as the wall material. A new core-shell composite disinfectant powder, MgO / MMPP- Al2O3 / MMPPand activated clay / MMPP / MMPP, was prepared by fluidized bed coating technology. The microcosmic morphology, particle size, dispersion properties of the composite disinfectant powder were studied by using hydroxypropyl methyl cellulose (HPMC) / MMPP as control. Stability and sterilizing ability of 2-CEES. The results showed that the compound disinfectant powder had good thermal stability and sterilizing ability while improving the dispersibility of MMPP. The disinfection rate of 2-CEES by MgO / MMPP / Al2O3 / MMPP was higher than that of 2-CEES by MgO / MMPP. The main products were 2-chloroethyl sulfoxide and 2-chloroethyl sulfone. The composite disinfectant prepared by fluidized bed has better disinfection ability than MMPP, which provides technical support for the development of new adsorptive reactive detergent.
