Effect of charge and molecular on flocculent performance of Polyacrylamide and cationic PolyvinylformamideC...

研究结果表明：(1)pH值对废水的色度、浊度以及电荷性质有很大的影响，从而对絮凝剂的絮凝性能产生影响；(2)C-PNVF在酸性条件下，电荷密度越低絮凝效果越好：中、碱性条件下，则相反；(3)分子量对各种电荷性质的PAM的絮凝性能的影响规律各不相同。

After treated by alkaline peroxide, the extractive in jack pine TMP long fiber decreased evidently, its surfaces produced large numbers of carboxyl. The H2O2 dosage in AP treated process had evident effect on brightness of sheet. The action of alkali in AP process is to make structure of cell wall loose.

碱性过氧化氢处理 TMP长纤维组分能明显降低浆中抽出物含量，纤维表面产生大量的羧基；过氧化氢用量的变化对白度影响较为明显；碱的作用是使细胞壁结构变得松弛，随着用碱量的增加，抽出物含量明显降低，羧基含量大幅度增加，纤维表面O/C比也略有增加，各项强度均增加。2。

This kind of material can be made as the compound cement quick-setting additiv e--D-quick-setting additive which can decrease the alkalinity of the quick-set ti ng additive but increase the viscosity of the jet materials.

针对目前国内速凝剂存在的普遍问题，我们经过反复试验、研究，选出一种辅料，制成可降低速凝剂碱性、增加喷射料粘度的复合型水泥速凝剂--D型速凝剂。

Carrageenan stability is very good, even if the long-term place will not reduce its gel strength and viscosity, in neutral and alkaline solution even if the heating or hydrolysis, carrageenan and konjac gum, locust bean gum, yellow The original plastic, such as colloidal shared use, can play a significant synergies can significantly change the characteristics of gel, gel flexible and retention.

卡拉胶的稳定性非常好，即使长期放置也不会降低其凝胶强度和粘度，在中性和碱性溶液中即使加热也不水解，卡拉胶与魔芋胶、刺槐豆胶、黄原胶等胶体共用使用，可发挥显著的协同增效作用能明显改变其凝胶特性、使凝胶富有弹性和保水性。
