摘要
含有复合酯包裹剂的化肥在使用过程中存在成本较高、残余物难于有效降解、施肥操作要求高等问题,选用乙二胺月桂酸盐(YP-3)和乙二胺硬脂酸盐(YP-7)两种物质来代替原包裹剂中的复合酯.对几种包裹剂的防结块性、黏度、防潮性、白度和光泽保持时间做对比研究,结果表明,含有YP-7的包裹剂对化肥具有较佳的防潮、防结块性能.
Abstract
For the purpose of coating fertilizer containing compound esters in the use of high cost,residue difficult degradation,fertilization opera-tion requirements of high problems,this study to find the ethylenediamine laurate(YP-3)and ethylenediamine stearate(YP-7)to replace the compound ester in the original coating agent,after several different coating block,viscosity,moisture resistance,whiteness and luster retention time,the results show that the coating agent containing YP-7 has a better moisture-proof performance for fertilizer.
