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，點燃后用于配制化驗試劑或藥品制劑的加熱，銅陵晶硝硫酸鈉廠家，也可用其火焰臨時消毒小型醫(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，這是錯誤的。酒精消毒的作用是凝固細菌體內(nèi)的蛋白質(zhì)，從而殺死細菌。但95%的酒精能將細菌表面包膜的蛋白質(zhì)迅速凝固，并形成一層保護膜，銅陵晶硝硫酸鈉廠家，阻止酒精進入細菌體內(nèi)，因而不能將細菌徹底殺死。如果酒精濃度低于70%，雖可進入細菌體內(nèi)，但不能將其體內(nèi)的蛋白質(zhì)凝固，同樣也不能將細菌徹底殺死。只有70%-75%的酒精即能順利地進入到細菌體內(nèi)，又能有效地將細菌體內(nèi)的蛋白質(zhì)凝固，因而可徹底殺死細菌。<br/> 無水***鈉，俗稱元明粉，是非常常見的粉末型礦產(chǎn)無機化學(xué)原料。銅陵晶硝硫酸鈉廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="銅陵晶硝硫酸鈉廠家,硫酸鈉"
