摘　　要：利用隧道窑作为干燥聚合设备,采用磷酸尿素缩合法开展聚磷酸铵生产试验,考察隧道窑的温度、料浆停留时间、匣钵布料厚度以及匣钵单双层摆放方式对所得聚磷酸铵产品品质的影响。多组试验数据表明,隧道窑能生产出合格的水溶性聚磷酸铵产品,但更适合于生产高聚合度、水不溶性聚磷酸铵产品。Using tunnel kiln as drying polymerization equipment,the production experiment of APP is carried out by urea phosphate condensation method.The effects of tunnel kiln temperature and residence time of material,the distribution thickness of sagger and the placement mode of single and double layers of sagger on the quality of APP products are studied.Several groups of experimental data show that the tunnel kiln can produce qualified water-soluble APP products,which may be more suitable for the production of high polymerization and water-insoluble APP.
