The results showed that the viscosity of the polymer solution increased with addition of SDBS and reached to a maximum value, then decreased with further addition of SDBS. The surface tension of the mixture solution decreased with the increase of SDBS concentration. The results have been discussed.展开更多
以不同相对分子质量的聚乙二醇与马来酸酐制备马来酸单酯,再与丙烯酸聚合生成马来酸 单酯-丙烯酸共聚物。较佳反应条件为:酯化反应温度75℃,投料比n(醇)∶n(酸酐)=1∶1.05, 反应时间1h;聚合温度85℃,(MAG)∶m(AA)=1∶1,(引发剂)=1.5%...以不同相对分子质量的聚乙二醇与马来酸酐制备马来酸单酯,再与丙烯酸聚合生成马来酸 单酯-丙烯酸共聚物。较佳反应条件为:酯化反应温度75℃,投料比n(醇)∶n(酸酐)=1∶1.05, 反应时间1h;聚合温度85℃,(MAG)∶m(AA)=1∶1,(引发剂)=1.5%,反应时间6h。将马来酸单 m w 酯-丙烯酸共聚物与其他非离子表面活性剂复配,从中筛选出较佳的脱墨剂配方∶m(AZ- 1000)∶m(AESM-9)∶m(NPSS-10)=2∶3∶3,同时采用如下脱墨工艺:(NaOH)=2%,(NaSiO3)=3%, w w w(脱墨剂)=0.3%,(过氧化氢)=2%,(EDTA)=0.2%,可使脱墨纸浆白度达64.3%ISO,残余油 w w 墨量为2.4mm2/g,得率77.6%。展开更多
