凝胶型树脂
凝胶型树脂
Gel resin
凝胶型树脂的高分子骨架，在干燥的情况下内部没有毛细孔。它在吸水时润胀，在大分子链节间形成很微细的孔隙，通常称为显微孔(micro-pore)。湿润树脂的平均孔径为2～4nm(2×10－6 ～4×10－6mm)。
The polymer skeleton of gel type resin has no pores in dry condition. It expands when absorbing water and forms very fine pores in the internodes of macromolecular chains, commonly called micro-pore. The average pore size of wetting resin is 2 ~ 4nm (2 x 10-6 ~ 4 * 10 - 6 mm).
这类树脂较适合用于吸附无机离子，它们的直径较小，一般为0.3～0.6nm。这类树脂不能吸附大分子有机物质，因后者的尺寸较大，如蛋白质分子直径为5～20nm，不能进入这类树脂的显微孔隙中。
These resins are more suitable for absorbing inorganic ions, and their diameters are small, usually 0.3 ~ 0.6Nm. This kind of resin can not adsorb large molecular organic matter, because the size of the latter is larger, such as the diameter of the protein molecule is 5 ~ 20nm, and can not enter the micropores of this kind of resin.
