Sodium polyacrylate has special ef

3、fect on protein in Biology. In addition, it is used as tackifier, drilling fluid filtrate reducer, clay stabilizer in the oil field chemistry of petroleum industry,also it can be used for acidizing fluid, pharmaceutical, cosmetics and other aspects of the thickener etc.Sodium polyacrylate can be synthesized by the bulk polymerization, solution polymerization, inverse suspension polymerization, inverse emulsion polymerization, microwave synthesis and radiation synthesis etc. Through consulting a

4、number of literature, surfing on the internet and researching market, I use inverse emulsion polymerization to product sodium polyacrylate. There are Sodium acrylate solution that had been neutralized， dispersion medium and dispersant in the reactor, The polymerization reaction under the effect of initiator will be carry on until azeotropic dehydration, the generated mixture will be separated of the polymer and remnant dispersion medium by the machine. Finally，the polymer transform into the comp

5、letion by the post processing such as drying, metering and packing.The design according to the design tasks are assigned the task of the book, the production conditions are discussed. The type of dispersant, monomer concentration, polymerization temperature effect on the molecular weight, the effects of stirring speed, determination the degree of neutralization, the selection of the separating method and drying method in the end ensure that polymerization reaction is implemented through using Sp

6、an-60 as dispersant, raffinate oil as dispersing medium, ammonium persulfate as initiator, sodium acrylate whose neutralization degree is 100% as monomer. After that, separating by using the centrifuge, drying by airflow dryer.The scale of the design for the sodium polyacrylate is1000 tons per year，according to 330 days a year，2 shift a day, 8 working hours a shift, they can produce two batches in a shift, the yield of each batch is 773.04kg. Then mentioned safety production standardization and

7、the measure of environmental protection.Professor XuChunHua, guiding by the director originally, had submitted a lot of valuable and positive suggestions, had helped me to raise the design mass. Here, I express my sincere thanks to them. Throughout the design process, I had a comprehensive understanding of their production process. According to my professional knowledge, combined with the learning experience, flexible application, laid a basis for future work related.Because of the wide range of

8、 knowledge of the design of Polyacrylate sodium process, and my knowledge and experience is limited. So having design errors and anything wrong with that, I urge marking teacher criticism.目录1前言12聚丙烯酸钠的概述12.1聚丙烯酸钠性能22.2聚丙烯酸钠的分类2低分子量聚丙烯酸钠2高分子量聚丙烯酸钠32.3聚丙烯酸钠的应用32.4聚丙烯酸钠国内外生长状况及生长前景43聚丙烯酸钠生产工艺63.1聚丙烯酸钠的聚合要领6水溶液聚合6反相乳液聚合6微波法6辐射聚合7反相悬浮聚合74聚合历程中工艺条件简直定84.1疏散剂及其助疏散剂对分子量的影响84.2引发体系的选择及其浓度对分子量的影响84.3交联剂对分子量的影响94.4单体浓度对分子量的影响94.5聚合温度对分子量的影响104.6聚合升温控制对聚合稳定性的影响104.7搅拌转速的影响114.8中和度的选取114.9疏散要领的选择124.10干燥要领的选
