AAHAPS共聚物阻垢性能研究林保平

①AA/HAPS林保平　王国力　顾叙元　郭　航(,210096)　　本文合成了一系列AA/HAPS共聚物,探讨了共聚组成、共聚物浓度、pH值、钙离子浓度及温度对共聚物组垢率的影响。研究结果表明,AA/HAPS共聚物具有优异的阻碳酸钙垢和阻磷酸钙垢性能。:共聚物,阻垢率,碳酸钙,磷酸钙,,,,。,-,。(AA)2--3--1-(HAPS)[1,2]。AA/HAPS,,、、pH。1　实验部分1.1　AA、;;HAPS。1.2　AA/HAPS、、500ml、,N2,80℃。AA、HAPS2h,90℃,2h,,,。AA/HAPS1。1　AA/HAPSAA/HAPS(mol)100/092/888/1284/1680/20(%)27.427.227.127.027.1*(dL/g)0.20180.20160.20170.20130.2013　　*30±0.05℃,1mol/LNaCl。1.3　EDTA[3]。pH第22卷　第1期1996年2月　　　　　　　　　　　　　　TECHNOLOGYOFWATERTREATMENT　　　　Vol.22No.1Jan.,1996①:95-07-17DOI:10.16796/j.cnki.1000-3770.1996.01.011。[4]。2　结果及讨论图1　共聚组成与阻垢率的关系2.1　1。()258mg/L,()200mg/L,pH9.2,8mg/L,60℃18h,AA/HAPSHAPS。HAPS,HAPS,,。,/(HPA),/2--2--1-(AMPS),,。AA/HAPS,HAPSmol20%,,。,AA/HAPS,、,。AA/HAPS。2()245mg/L,5mg/L,10mg/L,pH9.15,80℃10h。,AA/HAPSHAPS。,,AA/HAPSAA/HPA、AA/AMPS,,。2.2　AA/HAPS(PAA)(3),()258mg/L,()200mg/L,pH9.2,60℃18h,AA/HAPSPAA。AA/HAPS8mg/L,,,8mg/L,,。PAA15mg/LAA/HAPS,PAA15mg/L,。,PAA,。AA/HAPS,,,AA/HAPS,,[5]。4522　1　,AA/HAPS图2　共聚组成与阻垢率的关系图3　阻垢剂浓度与阻垢率的关系HAPS:×——0%;●——8%2.3　4()200mg/L,8mg/L,pH9.2,60℃18h。,。,;,。,HAPS,。,HAPS,。图4　Ca2+浓度与阻垢率的关系HAPS:×-0%;●-8%;○-16%图5　阻垢率与pH值的关系HAPS:×-0%;●-8%;○-16%2.4　pHpH。5()258mg/L,()200mg/L,8mg/L,60℃18hpH。,pH9.5,pH4622　1　　;9.5pH10.0,;pH10.0,。pH,,。,HAPS,pH。图5　阻垢率与温度的关系HAPS:×-0%;●-8%;○-16%2.5　6()258mg/L,()200mg/L,8mg/L,pH9.2,10h。50℃,,,,[3]。,HAPS,,AA/HAPSPAA。3　结　　论,AA/HAPS。、pH,HAPS,。1　ImaiT,UchidaT,AnoS,TsunekiT,MaterialsPerformance,1989,(5):412　,,1992,(5):33　,,,1987,(3):294　,,,1987,(2):185　　,,,1993,(4):7SCALEINHIBITIONPROPERTIESOFAA/HAPSCOPOLYMERSLinBaopin,WangGuoli,GuXuyuanandGuoHang(DepartmentofChemicalEngineering,SoutheastUniversity,Nanjing210096)Abstract:AseriesofAA/HAPScopolymerwerepreparedbycopolymerizationofacrylicacid(AA)and2-hydroxy-3-allyloxy-1-propanesulfonate(HAPS).Theeffectofcopoly-merstructure,copolymerconcentration,pHvalue,Ca2+concentrationandtemperatureontheratioofscaleinhibitionofcopolymerswasdiscussed.ItwasfoundthatAA/HAPScopolymerhadexcellentpropertiesofinhibitingCaCO3scaleandCa3(PO4)2　scale.Keywords:copolymer,ratioofscaleinhibition,calciumcarbonate,calciumphosphate.4722　1　,AA/HAPS
