浅谈新型制盐专用阻垢剂的开发和性能评价

Brief Discussion on the development and performance evaluation of new scale inhibitor for salt production

丙烯酸(AA)、丙烯酸羟丙酯(HPA)和丙烯磺酸钠(SAS)为单体,水为溶剂,过硫酸钠和过硫酸铵为引发剂,合成了三元共聚PAHS,该三元共聚物与天冬氨酸、聚环氧琥珀酸、AA-AMPS等复配,形成高效能的制盐专用阻垢剂ZNGY-306SH,能有效降低加热室结垢倾向,缓解蒸发罐结块盐,提高成品盐的白度,对成品盐的质量不产生任何影响。

Acrylic acid(AA),hydroxypropyl acrylate(HPA)and sodium propylene sulfonate(SAS)were used as monomers,water was used as solvent,sodium persulfate and ammonium persulfate were used as initiators to synthesize terpolymer PAHs.The terpolymer was mixed with aspartic acid,polyepoxy succinic acid,AA-AMPS,etc.,to form a highly efficient scale inhibitor ZnGY-306SH for salt production.It can effectively reduce the tendency of scaling in the heating chamber,relieve the agglomeration of salt in the evaporation tank,and improve the whiteness of the finished salt without any influence on the quality of the finished salt.
