　　75%的酒精消毒不需要兌水稀釋，可以直接使用。醫(yī)學(xué)上使用的酒精基本都是75%濃度的酒精，這種酒精可以有效的殺滅細(xì)菌與病毒，并且不會(huì)對(duì)人體產(chǎn)生不良影響。如果在75%濃度的酒精中兌水，反而會(huì)降低酒精濃度，起不到明顯的消殺作用。

75%的酒精消毒需要用水稀釋嗎

　　75%的酒精消毒不需要稀釋

　　75%濃度的酒精是醫(yī)學(xué)上最常使用的，這種濃度的酒精可以比較有效的殺滅物品或者皮膚表面的細(xì)菌或者病毒，并且不會(huì)對(duì)人體皮膚或者呼吸道造成刺激作用。所以，在使用75%的酒精消毒時(shí)不需要兌水，可以直接使用。

　　75%的酒精消毒兌水起不到作用

　　如果在使用75%濃度的酒精進(jìn)行消毒時(shí)，在酒精中兌水，會(huì)降低酒精濃度，并且起不到明顯的消殺作用，反而會(huì)因?yàn)闊o(wú)用的消殺導(dǎo)致細(xì)菌感染并擴(kuò)散。所以在使用酒精消毒過(guò)程中一定要注意酒精濃度。

　　75%以上的酒精消毒需要兌水

　　在使用75%濃度以上的酒精進(jìn)行消毒時(shí)，一定要在酒精中兌水，否則高濃度的酒精會(huì)對(duì)人體的皮膚、呼吸道等產(chǎn)生刺激，引發(fā)不良反應(yīng)。并且高濃度的酒精對(duì)于細(xì)菌蛋白脫水過(guò)于迅速，會(huì)在表面形成包膜，反而不能起到明顯的殺菌作用。
