| 摘 要： | 通过碱性水解将端酯基的半代树枝状聚酰胺-胺(Gn.5PAMAM)改性为外层基团为羧酸钠的阴离子树枝状聚酰胺-胺(A-Gn.5PAMAM),并通过红外光谱进行了结构表征。将A-Gn.5PAMAM作为有机阴离子微粒组分与星形阳离子聚丙烯酰胺(S-CPAM)及阳离子聚丙烯酰胺(CPAM)组成有机微粒助留助滤体系,系统地研究了该有机微粒体系对漂白旧报纸脱墨浆的助留助滤效果。结果表明,S-CPAM(CPAM)-(A-Gn.5PAMAM)有机微粒体系对纸料具有较好的助留助滤作用效果;高代数的A-Gn.5PAMAM对纸料小絮块的絮聚能力优于低代数产物;该有机微粒助留助留体系可以适应较宽的pH值范围,且抵抗高剪切作用的能力较强。研究同时表明,A-Gn.5PAMAM有机阴离子微粒与膨润土无机阴离子微粒具有很好的协同作用。

| Abstract: | The anionic PAMAM dendrimers were obtained through hydrolyzing the ester-terminated groups of Gn.5PAMAM in NaOH solution, the structure of obtained A-Gn.5PAMAM was characterized by FT-IR. The A-Gn.5PAMAM of different generations were used as organic anion microparticles for the microparticle retention and drainage system of the bleached deinked ONP. The results showed that the A-Gn.5PAMAM combined with S-CPAM and CPAM could provide higher furnish retention, and the efficiency of higher generation of A-Gn.5PAMAM was higher than that of the lower one. The S-CPAM (CPAM)/A-Gn.5PAMAM system could adapt to a broad pH range, and the retention and drainage system had better shearing resistance. It also found that the A-Gn.5PAMAM had a strong synergetic effect with bentonite as anionic particulate in the microparticle retention and drainage aid system. |
