一、铬酸的一般性质:1.固体的铬酸是红紫色,在水溶液中生成烟雾时发黄色。铬酸能够在水里溶解,如果手沾染了这种溶液,日久手指手掌就染上黄色,用水较难洗掉。2.它比空气重,较难随空气逸出室外,因此影响车间工人的健康。二、铬酸怎样引起人中毒:在电镀行业中,铬酸工段过去曾发生过中毒事故,在制造铬酸的工业中亦同样可能发生,虽然行业不同,但中毒原因大致相同。例如:1.从呼吸道吸入中毒:如果镀槽没有动力吸风装备时,铬酸一定向鼻子、口腔里钻。如果不戴防护面
First, the general nature of chromic acid: 1. Solid chromic acid is purple, yellow when the smoke generated in aqueous solution. Chromic acid can dissolve in the water, if the hand stained with this solution, the fingers of the fingers with the yellow color, washed with water more difficult to wash. 2. It is heavier than air and difficult to escape outdoors with air, thus affecting the health of workshop workers. How chromic acid can cause human poisoning: In the electroplating industry, the chromic acid station has had a poisoning accident in the past and may also occur in industries that manufacture chromic acid. Although the industries are different, the causes of poisoning are broadly the same. For example: 1. Inhalation from the respiratory tract poisoning: If the plating tank is not powered suction equipment, chromic acid must be to the nose, drill in the mouth. If you do not wear protective surface
