磷酸脲UREA PHOSPHATE( UP)
分子式：H3PO4·CO（NH2）2
分子量：158.0
執(zhí)行標準：Q74465717-10（工業(yè)級）
Q74465717-11（食品級）
性狀
外觀為白色粒狀晶體，極易溶于水，不溶于***。熔點為117.3°C，水溶液呈強酸性，1%水溶液PH值為1.89，熱穩(wěn)定性小，受熱易發(fā)生分解反應。
用途
磷酸脲是一種優(yōu)良的***，它為性畜提供磷和非蛋白氮（尿素態(tài)氮）兩種營養(yǎng)元素，安全性比尿素高。它還是一種高濃度氮磷復合肥料（總養(yǎng)分元素61%），適用于堿性土壤。除用作飼料、肥料外，還可以作阻燃劑，金屬表面處理劑、發(fā)酵營養(yǎng)劑、清洗劑及凈化磷酸用助劑等。
包裝貯存
內(nèi)塑外編袋、紙袋、PE袋，每袋凈重25、50、1000kg，貯于通風干燥處。
