【摘要】：以環(huán)氧琥珀酸(ESA)、衣康酸(IA)和苯乙烯磺酸鈉(SS)為單體,過(guò)硫酸銨為引發(fā)劑,通過(guò)共聚反應(yīng)得到了含有羧基和磺酸基的三元共聚物ESA/IA/SS,利用FTIR對(duì)其結(jié)構(gòu)進(jìn)行了表征�？疾炝藛误w質(zhì)量比、引發(fā)劑用量、聚合溫度和聚合時(shí)間對(duì)ESA/IA/SS阻碳酸鈣垢性能的影響。實(shí)驗(yàn)結(jié)果顯示:ESA/IA/SS的最佳合成條件為m(馬來(lái)酸酐,MA)∶m(IA)=3∶1,SS的加量為20%(占單體總質(zhì)量,下同),引發(fā)劑的加量為12%,聚合溫度85℃,聚合時(shí)間4 h,此時(shí)得到的產(chǎn)品黏均相對(duì)分子質(zhì)量為1 176.3。對(duì)ESA/IA/SS的阻垢和分散氧化鐵性能進(jìn)行了測(cè)定,并與ESA/SS和聚環(huán)氧琥珀酸(PESA)進(jìn)行了比較。實(shí)驗(yàn)結(jié)果表明:當(dāng)阻垢劑的質(zhì)量濃度均為50 mg/L時(shí),ESA/IA/SS與PESA的阻碳酸鈣垢性能相當(dāng),PESA的阻垢率為72.3%,ESA/IA/SS的阻垢率為71.5%,而ESA/SS的阻垢率僅為44.2%。當(dāng)阻垢劑的質(zhì)量濃度均為40 mg/L時(shí),ESA/IA/SS的阻磷酸鈣垢性能遠(yuǎn)高于PESA,PESA的阻垢率僅為7.0%,ESA/IA/SS的阻垢率為96.8%。同時(shí),當(dāng)加入阻垢劑的質(zhì)量濃度為30 mg/L時(shí),ESA/IA/SS還具有一定的分散氧化鐵性能,加藥后Fe Cl3溶液的透光率為72.6%。
[Abstract]:The monomers of ESAA, iaconic acid and sodium styrene sulfonate were used as monomers and ammonium persulfate as initiator. A terpolymer containing carboxyl group and sulfonic group was obtained by copolymerization. The structure of the copolymer was characterized by FTIR. The mass ratio of monomer and the amount of initiator were investigated. The effect of polymerization temperature and polymerization time on the scale inhibition of calcium carbonate by ESA/IA/SS. The experimental results show that the optimum synthesis conditions of ESA/IA/SS / EA / IA / SS are as follows: M (maleic anhydride MA1: MIAA 3: 1SS = 20) (the mass of monomer is the same, the amount of initiator is 12, the polymerization temperature is 85 鈩，
