1-甲氧基-2丙醇1-Methoxy-2-propanol氣體檢測管10-500ppm

簡(jiǎn)要描述:

環(huán)己酮氣體檢測管 丙二醇甲醚 1-甲氧基-2丙醇1-Methoxy-2-propanol氣體檢測管10-500ppm 丙二醇醚與乙二醇醚同屬二元醇醚類(lèi)溶劑,丙二醇醚對人體的毒害性能低于乙二醇醚類(lèi)產(chǎn)品,可視為無(wú)毒或低微毒性產(chǎn)品,由于其分子結構中既有醚官能基又有羥基,因而它的溶解性能十分優(yōu)異,又有合適的揮發(fā)性以及反應活性等特點(diǎn)而獲得廣泛的應用,除用于多種高檔涂料的溶劑之外,還可用于化學(xué)中間體、剎車(chē)液、清洗劑、防冰劑等諸多領(lǐng)域。
