以上海医疗器械二厂制造的“70型”为代表的小型去离子水交換器,体积小,重量轻,出水量较大,使用方便,很适合于小型实验室、野外工作,农村四级科技网及基层医疗卫生单位使用。因此该产品的出厂量很大,现在几已遍体全国各地。用此种交換器制取去离子水交换效果不错,如使用恰当,可以制备阻率超过800万Ω以上的超纯优质水。我们用“70型”制备出的合格去离子水,供给我校物理系用于制造激光管的清洗水,效果较好,
The small-sized deionized water exchanger represented by the “70 Model” manufactured by Shanghai Medical Devices No. 2 Plant is small in size, light in weight, and has a large amount of water and is easy to use. It is suitable for small-scale laboratories and field work. Net and primary health care units use. Therefore, the factory volume of this product is very large, and now it has been spread all over the country. The exchange of deionized water with this exchanger is effective, and if used properly, ultra-pure, high-quality water with a resistivity of more than 8 million ohms can be prepared. The qualified deionized water that we prepared with the “70 type” is supplied to our school’s physics department for manufacturing the cleaning water of the laser tube.
