在X射线衍射仪测量中常需将粉末样品压附在玻璃样品支承板上,但有时常因粉末颗粒较粗,不易压紧,而在试验过程中掉落下来,使试验失败。为了防止粉末掉落,我们常用1～3%聚苯乙烯二甲苯溶液(即在100毫升二甲苯溶液中加入1～3克聚苯乙烯,亦可用甲苯或苯溶液,用苯时有一定毒性需加以注 In the X-ray diffractometer measurement powder samples often need to be attached to the glass sample support plate, but sometimes often because the powder particles thicker, not easy to compress, and drop in the test process, so that the test failed. In order to prevent powder from falling, we often use 1 to 3% polystyrene xylene solution (ie add 1 to 3 g polystyrene in 100 ml xylene solution, also use toluene or benzene solution, use benzene to have certain toxicity need Note
