style="text-indent:25px">酒精的用途是很多的，不同濃度的酒精用途是不一樣的，你們了解多少呢?其實(shí)我們可以了解的事很多的，我們的酒精在生活中的用途是很***的，不知道你們了解多少呢?小編在這里想給各位來介紹一下不同濃度酒精的用途，我知道具體的你們是不是那么清楚的，那么下面一起來看看吧!<br/> 一、95%的酒精用做燃料<br/> 醫(yī)療單位常需使用酒精燈、酒精爐，點(diǎn)燃后用于配制化驗(yàn)試劑或藥品制劑的加熱，也可用其火焰臨時(shí)消毒小型醫(yī)療器械。<br/> 二、70%-75%的酒精用于滅菌消毒<br/> 用于包括皮膚消毒、醫(yī)療器械消毒、碘酒的脫碘等。<br/> 有人以為，酒精濃度越高，消毒效果越好，這是錯(cuò)誤的。酒精消毒的作用是凝固細(xì)菌體內(nèi)的蛋白質(zhì)，從而殺死細(xì)菌。但95%的酒精能將細(xì)菌表面包膜的蛋白質(zhì)迅速凝固，并形成一層保護(hù)膜，阻止酒精進(jìn)入細(xì)菌體內(nèi)，因而不能將細(xì)菌徹底殺死。如果酒精濃度低于70%，雖可進(jìn)入細(xì)菌體內(nèi)，但不能將其體內(nèi)的蛋白質(zhì)凝固，同樣也不能將細(xì)菌徹底殺死。只有70%-75%的酒精即能順利地進(jìn)入到細(xì)菌體內(nèi)，又能有效地將細(xì)菌體內(nèi)的蛋白質(zhì)凝固，因而可徹底殺死細(xì)菌。<br/>
