一种新型抗铁污染型膜专用阻垢剂的制备方法
摘要：
本发明一种新型抗铁污染型膜专用阻垢剂的制备方法，涉及一种膜专用阻垢分散剂的制备方法，其组成为聚环氧琥珀酸钠（PESA，10%-30%），2-膦酸丁烷-1,2,4-三羧酸（PBTCA，10%-30%）丙烯磺酸盐共聚物（AA/AMPS，5%-15%）、苯乙烯磺酸（SS，1%-5%）、水解聚马来酸酐（HPMA，2%-8%），其余为蒸馏水。本发明产品在高碱、高硬、高pH值的水质条件下，在有铁离子存在下的，阻碳酸钙和硫酸钙垢达100%，提高了对二氧化硅、硫酸钡、硫酸锶等垢的阻垢性能。
摘要（英）：

The invention discloses a novel preparing method for a scale inhibitor special for an iron-pollution-resistant film, and relates to a preparing method for a film-special scale inhibiting-dispersing agent. The scale inhibitor is prepared from 10%-30% of polyepoxysuccinic acid (PESA), 10%-30% of 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA), 5%-15% of an allyl sulfonic acid salt copolymer (AA/AMPS), 1%-5% of styrene sulfonic acid (SS), 2%-8% of hydrolytic polymaleic anhydride (HPMA) and the balance distilled water. According to the scale inhibitor, under the condition of high-alkali, high-hardness and high-pH-value water quality and existence of iron ions, calcium carbonate scale inhibition and calcium sulfate scale inhibition reach 100%, and the scale inhibition performance for silicon dioxide scale, barium sulfate scale, strontium sulfate scale and the like is improved.
