基于MATLAB的AA-HPA-AMPS-AM聚合物阻垢剂合成及其性能研究

Researches on Preparation and Properties of AA-HPA-AMPS-AM Polymer Scale Inhibitor Based on MATLAB

通过溶液聚合方法,以过硫酸铵为引发剂,丙烯酸、丙烯酸羟丙酯、2-丙烯酰胺-2-甲基丙磺酸、丙烯酰胺为单体,合成AA-HPA-AMPS-AM聚合物。固定聚合物浓度为4 mg/L,分别考查反应时间、反应温度(X_1)、引发剂用量(X_2)、单体配比(AA:HPA以X_3计、AMPS:AM以X_4计)对聚合物阻CaCO_3垢性能的影响,并设计了正交实验,得出当聚合物在80℃、引发剂用量为10%、M(AA):M(HPA)为0.25、M(AMPS):M(AM)为0.4时,阻CaCO_3垢率最高为52.9%。为探究此聚合物是否有更高的阻垢性能,应用MATLAB对正交实验结果进行分析及验证,得知:聚合物阻CaCO_3垢效率y与各影响因素X之间基本满足y=146.3497-0.926 7x_1-49.765 8x_3-28.220 9x_4。最佳聚合条件为x_1=75、x_3=0.15、x_4=0.15,y为68.35%。

By solution polymerizalion method, AA-HPA-AMPS-AM polymer is cmnposed by acrylic acid, hydroxypropyl acrylate,2-acrylan- mide-2-methylpropanesulfonie acid and aerylam-ide,with ammonium persuffate as initiator. With polymer concentration fixed to 4 rag/L, the reaction time, reaction temperature （ X1 ） ,inltiator dosage （ X2 ） , monomer ratio （ X3 means M （AA） ： M （HPA） and X4 means M （AMPS） ： M（ AM ） ） to the rate of resisting the formation of calcimn carbonate are examined. The orthogonal experiment indicates that the highest rate of resisting CaCO3 is 52.9% in the case of reaction time at 80~C, and initiator dosage at 10%, M （AA） ：M （HPA） at 0.25, M （AMPS） ：M （ AM ） at 0.4. In order to explore whether this polymer has a higher antiscale performance, MATLAB is used to analyse and verify the results of orthogonal experiments. The result gives the relationship y = 146. 349 7 -0. 926 7x1 -49. 765 8x3 -28. 220 9x4 ,with antiscale efficiency against CaCO3 y and effect factors x. The best polymerization condition is found to be x1 =75 ,x3 =0.15 ,x4 =0. 15 and y =68.35%.
