[摘要]以衣康酸(1A)、丙烯磺酸钠(SAS)和次亚磷酸钠(SHP)为单体,合成兼具阻垢、缓蚀和分散性能的衣康酸共聚物(IA
SHP/SAS);考察了 LA/SHP/SAS与静电场的协同阻垢性能。静态阻垢实验结果表明,当静电电压为SkV、水浴温度为60℃
IA/SHP/SAS加人量为8mgL时,阻垢率提高了20.7%;动态阻垢实验结果表明,地下水经静电场(温度40℃)处理后,阻垢率
提高了12.6%。经静电场处理后,水垢中的文石型CaCO含量明显增多;静电场与 IA/SHP/SAS协同作用,加强了 JA/SHP/SAS对
CaCO2晶体的扭曲和分散作用,提高了CaCO的溶解度。IAS
对A3碳钢的缓蚀率最高可达93.1%,分散Fe2O时( IA/SHP
SAS加入量为30mgL)溶液的透光率为65.7%,28d时的生物降解率为69.5%,说明IA/ SHIP/SAS是可生物降解的阻垢缓蚀剂

I Abstract j An itaconic acid copolymer with scale inhibition, corrosion inhibition and dispersion
was synthesized. The synergistic scale inhibition of the copolymer(LA/SHP/SAS)with electrostatic
field was studied. The results of the static experiments showed that, under the conditions of
electrostatic voltage 5 kv, water bath temperature 60 C and the copolymer dosage 8 m/L, the
static scale inhibition rate was enhanced by 20.7%. In the dynamic experiments, after treatment with
electrostatic field(40), the scale inhibition was enhanced by 12. 6% and the content of aragonite type
Caco; in the scale increased obviously. The synergism of LA/SHP/SAS with the electrostatic field could
improve the distorting and dispersing effects of ASHP/SAS on aco; crystals, and then the solubility
of Caco; was enhanced. It was showed that, under the synergistic effect, the corrosion inhibition rate
to A3 carbon steel was 93. 1% and the light transmittance of the solution with dispersed Fe,O was 65.7
(IA/SHP/SAS dosage 30 mg/L). The biodegradation rate of 1A/SHP/SAS was 69.5%o in 28 d
