磷酸脲UREA PHOSPHATE( UP)
分子式：H3PO4·CO（NH2）2
分子量：158.0
执行标准：Q74465717-10（工业级）
Q74465717-11（食品级）
性状
外观为白色粒状晶体，极易溶于水，不溶于***。熔点为117.3°C，水溶液呈强酸性，1%水溶液PH值为1.89，热稳定性小，受热易发生分解反应。
用途
磷酸脲是一种优良的***，它为性畜提供磷和非蛋白氮（尿素态氮）两种营养元素，安全性比尿素高。它还是一种高浓度氮磷复合肥料（总养分元素61%），适用于碱性土壤。除用作饲料、肥料外，还可以作阻燃剂，金属表面处理剂、发酵营养剂、清洗剂及净化磷酸用助剂等。
包装贮存
内塑外编袋、纸袋、PE袋，每袋净重25、50、1000kg，贮于通风干燥处。
