絮凝

Brownian movement and the hydraulic condition required is only that the coagulant can be dispersed in the water rapidly;As the floc is growing further,the condition of making the floc diameters controlled in a certain limit is to be provided as well as the condition favorable for the collision of the floc.

得到细小粒子的凝集动力由布朗运动决定，此阶段只需要有将混凝剂迅速分散于水中的水力条件；在絮体进一步成长过程中除造成有利于絮体碰撞的水力条件外，还要造成絮体粒径控制在某一限度之内的水力条件，这样可以得到密度高、沉淀效果好的絮体。

SEM result showed that the sample had uniform phase distribution and smooth surface at dried state as well as interpenetrate network structure at hydrogel state. It was seen from the swell ing behavior curves that groups T1, T2 and T3 swelled rapidly within 10-30 minutes, and formed elastic composite hydrogel pipes. In addition, the expanding ratio of inner and outer diameter of the tube was 20%-30% and 100%-120% with swell ing, respectively. The equil ibrium water content of the hydrogel pipes increased with increase of collagen composition. Three groups of samples were immerged in PBS solution contained 2 mg/mL lysozyme at 37 for 1 month, their nozzle cracked, their wall became thin and more transparent. And also, there was small floc deposited on the tube surface.

扫描电镜观察到液氮脆断的人工泪小管内部成分分布均匀，内外壁表面平整，冷冻干燥的人工泪小管断口呈凝胶态的互穿网络结构。3 组不同成分的人工泪小管在PBS 溶液中浸泡30 min 后均快速吸水溶胀，外径扩大100%～ 120%，内径扩大20%～ 30%，并且随胶原含量增高，溶胀速度增快，平衡溶胀率增大。3 组人工泪小管在37℃含2 mg/mL 溶菌酶的PBS 液中浸泡1 个月后，表面有部分细小絮状物，管口开裂，管壁变薄，透明度增加。

The result of orthogonal experiment showed that the sequence of the factors affecting extraction ratio of the LPC was flocculation method, solid-liquid ratio and the amount of adding salt. The optimal combination condition was solid-liquid ratio 1:7, salt concentration 0.3% and ethanol precipitation method.
