The rate of polymerization in the production of carboxylated butadiene-styrene rubber latex was influenced by the change of polymerizing condition in fore-and-aft reactor cleaned and the efficient power of mixing in its reactor and the time of warming-up their materials. 在羧基丁苯胶乳生产中,清釜前后的聚合环境变化、聚合釜搅拌有效功率大小和预热时间长短都能影响聚合反应速率。
To meet the domestic demand of high grade road construction, Shengli Refinery of Qilu Petrochemical Company has studied and developed SBR latex modified asphalt and its application by on-spot mixing method. 为适应我国高等级道路建设的需要,齐鲁石化公司胜利炼油厂研究开发了现场拌和法丁苯胶乳改性沥青。
A method or preparing AAS resin which is made from the graft copolymerization of styrene and acrylonitrile on the rubber latex emulsion particles, then mixing with the emulsion obtained from the copolymerization of styrene and acrylonitrile is described ( the rubber phase is of merely the polybutylacrylate). 本文扼要介绍了以聚丙烯酸丁酯为主体的橡胶相,在橡胶乳粒上用苯乙烯和丙烯腈进行接枝共聚后,再与苯乙烯、丙烯腈共聚树脂的乳液共混而制得AAS树脂的生产方法。
NBR/ EG composites were prepared by latex compounding, direct blending and solution mixing methods. 采用乳液共混、直接共混及溶液共混等方法制备了丁腈橡胶/石墨复合材料,并用电子显微镜和X-射线进行了观察和衍射测试。
The test of rubber uniform degree of SBR latex modified asphalt mixture with on-spot mixing method 现场拌和法丁苯胶乳改性沥青混合料橡胶均匀度考察试验
