摘要
在实际的施工操作中,工艺介质多以混合物的状态存在。对于混合物的等级、压力管道规范、压力容器规范等均有不同的分类方法和选型特点。然而,实际生活中,除专业人员外很少有人了解混合物的毒性作用等级、分类方法和选型。文章将试析混合物毒性等级的分类方法及选型,探讨出适合进行其中毒性等级的分类方法及选型的方式方法。
In the actual construction operation,the process medium exists in the state of mixture.There are different classif ication methods and selection features for mixture grade,pressure piping specif ication and pressure vessel specif ication.However,in real life,apart from those who study this f ield professionally and those who have taken the initiative to know it,few people know the levels of toxicity,classif ication and type selection of mixtures.In this paper,the classif ication method and type selection of toxicity grade of mixture were analyzed,and the suitable classif ication method and type selection method were discussed.
