Different kinds of flocculants have different capabilities. The flocculants produced by Aspergillus parasiticus is not steady for heat. The flocculating effect is best at acid conditions, and it is not acute for Ca〓. The flocculant can decolorize soluble dyestuff, even the active gorgeous red X-3B which is difficult to be decolorized, the decolor rate is 62. 1%. The flocculant produced by A-9 is steady for heat. It can flocculate Gaolin suspension well without synergistic effects of CaCl〓, and the dose is only 0.05ml/L.

One or diarrhea should not take the time (including acute diarrhea and chronic diarrhea at the time) because of diarrhea will hemoconcentration, increased blood viscosity, and diuretics the blood will also concentrated, so if patients with diarrhea when taking diuretics would become a higher blood viscosity, it is easy to lead to the formation of thrombus, and there may be serious consequences such as myocardial infarction.

一、腹泻时不宜服用(包括急性腹泻时和慢性腹泻时)因为腹泻会使血液浓缩、血黏度增高，而利尿剂也会使血液浓缩，所以如果患者在腹泻时服用利尿剂就会使血黏度变得更高，很容易导致血栓的形成，并可能会出现心肌梗死等严重后果。

The interfacial viscosity of HPAM-CTAB system at hexadecane-water interface was much higher than that of HPAM solution alone at hexadecane-water interface, indicating that there exists significant interaction between CTAB and HPAM; perhaps they could form complex which was adsorbed at the hexadecane/water interface, so the interfacial viscosity was increased.

HPAM和CTAB复配体系与正十六烷所成界面的界面粘度要比单一HPAM溶液与正十六烷所成界面的界面粘度要大一个数量级，这表明复配体系中CTAB和HPAM之间存在着明显的相互作用，这可能是因为两者之间形成复合物在油/水界面富集而使界面粘度升高。
