Ⅱ.关于电泳中的超滤1.超滤和超滤器将漆液用泵循环送至超滤器中的超滤管,通过有一定孔径的超滤膜,漆液中的水和小分子等透过,而树脂和颜料等大分子被截留。这种超滤膜是由内或外刮膜上的醋酸纤维素、丙酮、甲酰胺等试剂配制的粘液所形成。对阳极电泳超滤器来说,超滤膜是附在多孔烧结管上的。阳极电泳用的超滤器,国内已有多家生产。而阴极电泳超滤器,国内目前尚处于试制阶段。 2.为什么要超滤目前国内用的阳极电泳超滤系统如图8。
Ⅱ. Ultrafiltration in electrophoresis 1. Ultrafiltration and ultrafiltration The pump liquid is circulated to the ultrafiltration tube in the ultrafilter through an ultrafiltration membrane having a certain pore size, water in the paint liquid and small molecules Such as through the resin, and pigments and other macromolecules were intercepted. This ultrafiltration membrane is formed on the inner or outer scraping film of cellulose acetate, acetone, formamide and other reagents prepared mucus. For the anode electrophoresis ultrafilter, ultrafiltration membrane is attached to the porous sintered tube. Anode electrophoresis with ultrafiltration, there are already many domestic production. The cathode electrophoresis ultrafiltration, the domestic is still in the trial stage. 2. Why ultrafiltration currently used in domestic anodic electrophoresis ultrafiltration system shown in Figure 8.
