过去,我们曾用烘干称重法、加热法、脱溶比重计法等进行水溶性淬火介质浓度的测定。这些方法有的操作复杂,有的不够准确。目前我们采用了WZS-1型折射仪检测介质浓度,这种方法比较简单,只需很短时间便可测出结果。它能对单一介质、复合介质及带入的盐份进行浓度测定,适合于试验室和现场取样检测。这种方法是,在试验室内配制不同浓度的水溶性淬火介质,测定其折光率,从而得出折射率-浓度曲线,然后取未知浓度的淬火介质,测定其折射率,再通过
In the past, we have dried weighing method, heating method, decontamination pycnometer method for water-soluble quenching medium concentration determination. Some of these methods are complicated to operate and some are not accurate enough. Currently we use the WZS-1 refractometer to detect the concentration of the medium, this method is relatively simple, only a very short time can be measured out. It can be a single medium, composite media and brought into the salt concentration determination, suitable for laboratory and field sampling and testing. This method is in the laboratory preparation of different concentrations of water-soluble quenching medium, measuring the refractive index, resulting refractive index - concentration curve, and then take unknown quenching medium concentration, measured refractive index, and then by
