测定并比较了由典型的阴离子表面活性剂（SDS）、阳离子表面活性剂（OCTA）、非离子表面活性剂（TW－80）及其各自等摩尔混合体系处理而得的各类膨化硝铵的晶变性质及抗结块性，探讨了表面活性剂对膨化硝铵晶变性质的影响机理，并得出了效果较好的膨化硝铵抗结块剂。
Various types of expanded ammonium nitrate treated with typical anionic surfactants (SDS), cationic surfactants (OCTA), nonionic surfactants (TW-80) and their respective equimolar mixing systems were determined and compared Crystal properties and anti-caking property. The influence mechanism of surfactants on the crystalline properties of puffed ammonium nitrate was discussed, and the puffed ammonium nitrate anti-caking agent with better effect was obtained.
