融(rong)(rong)雪(xue)(xue)劑(ji)是(shi)什么東西呢？融(rong)(rong)雪(xue)(xue)劑(ji)是(shi)一種化學品。普(pu)通融(rong)(rong)雪(xue)(xue)劑(ji)原料(liao)易得，價格低廉，其成份(fen)主要是(shi)醋酸(suan)鉀和氯鹽，并以這(zhe)兩種進行分類。

溶雪劑(ji)能當防凍液(ye)用(yong)嗎(ma)？首先我(wo)們要了解防凍液(ye)的(de)作(zuo)用(yong)，它具有(you)防凍的(de)作(zuo)用(yong)和防銹的(de)能力。而溶雪劑(ji)也是(shi)具有(you)防凍融(rong)化的(de)作(zuo)用(yong)，那么溶雪劑(ji)能當防凍液(ye)用(yong)嗎(ma)？

   ;據(ju)了(le)解溶雪(xue)(xue)劑(ji)不允許用當防凍(dong)液(ye)用的。這是因為發動(dong)機冷卻液(ye)本來就必須用蒸餾(liu)水與(yu)防凍(dong)液(ye)混(hun)合(he)使用，不能只加純的防凍(dong)液(ye)，純的防凍(dong)液(ye)會引起水溫高，所(suo)以說溶雪(xue)(xue)劑(ji)是不行的。

   防(fang)凍(dong)液可提高我們(men)發(fa)動(dong)機冷(leng)(leng)卻(que)液的“沸點(dian)”（冷(leng)(leng)卻(que)水(shui)開鍋的溫度(du)），降低冷(leng)(leng)卻(que)水(shui)的“凝點(dian)”，使用(yong)壽(shou)命一(yi)(yi)般為1---2年，測(ce)量冷(leng)(leng)卻(que)液濃(nong)度(du)有專門的試(shi)紙條，防(fang)凍(dong)液的濃(nong)度(du)一(yi)(yi)般在(zai)35%---68%，一(yi)(yi)般車(che)輛推薦值為50%，即:50%防(fang)凍(dong)液+50%純凈(jing)水(shui)組成發(fa)動(dong)機冷(leng)(leng)卻(que)水(shui)。使用(yong)壽(shou)命一(yi)(yi)般為1---2年。一(yi)(yi)般就是(shi)我們(men)工業用(yong)的乙烯乙二(er)醇或烯乙二(er)醇。

融雪(xue)(xue)(xue)(xue)劑(ji)，顧(gu)名(ming)思義(yi)就是(shi)指可以降(jiang)低冰(bing)雪(xue)(xue)(xue)(xue)融化(hua)溫(wen)度的(de)藥劑(ji)，怎么生產液體融雪(xue)(xue)(xue)(xue)劑(ji)，是(shi)一種化(hua)學品(pin)。普(pu)通(tong)(tong)融雪(xue)(xue)(xue)(xue)劑(ji)原料(liao)易得，價格低廉，其成份主要是(shi)醋酸鉀和氯鹽，并以這兩種進行(xing)分類。融雪(xue)(xue)(xue)(xue)劑(ji)通(tong)(tong)過降(jiang)低冰(bing)雪(xue)(xue)(xue)(xue)融化(hua)溫(wen)度融化(hua)道路上的(de)積(ji)雪(xue)(xue)(xue)(xue)，便于道路疏通(tong)(tong)。

簡(jian)單地說，融雪劑(ji)的(de)作用原理是利用鹽水的(de)凝(ning)固點比水的(de)凝(ning)固點低(di)的(de)特點，實際上雪是在不斷融化和凝(ning)固的(de)，只不過二者速度相等，處(chu)于一(yi)種(zhong)平(ping)衡狀態，撒上鹽以(yi)后，雪周圍的(de)水就便成鹽水，但又未(wei)能凝(ning)固，這樣雪就會不斷融化，并會越來越少(shao)了。

溶(rong)(rong)(rong)(rong)(rong)(rong)解是一(yi)個(ge)物(wu)(wu)理化(hua)(hua)學過程，當(dang)溶(rong)(rong)(rong)(rong)(rong)(rong)質(zhi)(zhi)溶(rong)(rong)(rong)(rong)(rong)(rong)解在溶(rong)(rong)(rong)(rong)(rong)(rong)劑中(zhong)形(xing)成溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)后(hou)，溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)的性(xing)(xing)(xing)質(zhi)(zhi)已不同于(yu)原來的溶(rong)(rong)(rong)(rong)(rong)(rong)質(zhi)(zhi)和溶(rong)(rong)(rong)(rong)(rong)(rong)劑。溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)的某些性(xing)(xing)(xing)質(zhi)(zhi)與溶(rong)(rong)(rong)(rong)(rong)(rong)質(zhi)(zhi)的本性(xing)(xing)(xing)有(you)(you)關，如(ru)(ru)顏(yan)色、導電(dian)性(xing)(xing)(xing)等。但是溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)的另一(yi)類性(xing)(xing)(xing)質(zhi)(zhi)，如(ru)(ru)蒸氣(qi)壓下(xia)降(jiang)、沸點(dian)(dian)(dian)升高、凝固點(dian)(dian)(dian)降(jiang)低(di)及(ji)滲透壓，只與溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)中(zhong)溶(rong)(rong)(rong)(rong)(rong)(rong)質(zhi)(zhi)粒(li)子的濃度有(you)(you)關，而(er)與溶(rong)(rong)(rong)(rong)(rong)(rong)質(zhi)(zhi)的本性(xing)(xing)(xing)無關。由(you)于(yu)這(zhe)(zhe)類性(xing)(xing)(xing)質(zhi)(zhi)的變(bian)化(hua)(hua)，只適用(yong)于(yu)稀溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)，稱為稀溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)的依數性(xing)(xing)(xing)，如(ru)(ru)化(hua)(hua)冰鹽(yan)的水溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)的凝固點(dian)(dian)(dian)隨著鹽(yan)的濃度增加而(er)降(jiang)低(di)，一(yi)直降(jiang)低(di)到冰鹽(yan)合晶點(dian)(dian)(dian)，稀溶(rong)(rong)(rong)(rong)(rong)(rong)液(ye)(ye)的凝固點(dian)(dian)(dian)、沸點(dian)(dian)(dian)具有(you)(you)依數性(xing)(xing)(xing)，它與每(mei)1000g溶(rong)(rong)(rong)(rong)(rong)(rong)劑中(zhong)含溶(rong)(rong)(rong)(rong)(rong)(rong)質(zhi)(zhi)的物(wu)(wu)質(zhi)(zhi)的量的值有(you)(you)關，每(mei)上升1mol/1000水，凝固點(dian)(dian)(dian)下(xia)降(jiang)大(da)(da)約(yue)1．86℃。如(ru)(ru)若1000水中(zhong)溶(rong)(rong)(rong)(rong)(rong)(rong)有(you)(you)58.5gNaCl，也(ye)就是大(da)(da)約(yue)1mol，此鹽(yan)水的凝固點(dian)(dian)(dian)便大(da)(da)約(yue)是－3.72℃，這(zhe)(zhe)樣可由(you)鹽(yan)水的濃度大(da)(da)致推出其(qi)凝固點(dian)(dian)(dian)。
