大(da)顆(ke)粒(li)(li)(li)鹽(yan)(yan)又叫海鹽(yan)(yan)、粗鹽(yan)(yan)，或者日曬海鹽(yan)(yan)。顆(ke)粒(li)(li)(li)大(da)（顆(ke)粒(li)(li)(li)大(da)小可根據客(ke)戶的(de)(de)(de)要求研磨）。大(da)顆(ke)粒(li)(li)(li)鹽(yan)(yan)主(zhu)要用(yong)于(yu)(yu)熱敷和鍋爐水的(de)(de)(de)處(chu)理。油井鉆探過程中，為保護巖(yan)鹽(yan)(yan)層(ceng)巖(yan)心(xin)的(de)(de)(de)完(wan)整性，需在泥漿中添加鹽(yan)(yan)作穩定(ding)劑(ji)；在工業(ye)化時代之(zhi)前，人(ren)(ren)們所說(shuo)的(de)(de)(de)鹽(yan)(yan)，特指生活中調味(wei)用(yong)的(de)(de)(de)，而不是(shi)現在化學科學中的(de)(de)(de)“鹽(yan)(yan)”。關于(yu)(yu)開車一(yi)族來說(shuo)，冬季讓(rang)人(ren)(ren)無奈的(de)(de)(de)就是(shi)玻(bo)璃結(jie)(jie)霜結(jie)(jie)凍，可將工業(ye)鹽(yan)(yan)弄濕，用(yong)來擦洗擋風玻(bo)璃內面，可免(mian)除結(jie)(jie)冰或結(jie)(jie)霜的(de)(de)(de)懊惱(nao)。

我(wo)們(men)都知道工(gong)業(ye)鹽(yan)(yan)(yan)(yan)廣泛應用(yong)于(yu)工(gong)業(ye)行(xing)業(ye)上，那肯定(ding)有人會有疑問(wen)，工(gong)業(ye)鹽(yan)(yan)(yan)(yan)在工(gong)業(ye)上有什么(me)作(zuo)用(yong)？到底又是(shi)用(yong)來做(zuo)什么(me)的(de)(de)呢(ni)？此(ci)外，還用(yong)于(yu)肥皂制(zhi)(zhi)造(zao)、陶瓷、玻璃(li)生產、日用(yong)化(hua)(hua)工(gong)、石油鉆探(tan)、鉆井工(gong)作(zuo)液(ye)、完井液(ye)、石油化(hua)(hua)工(gong)脫水(shui)液(ye)、建筑行(xing)業(ye)早強劑、生產涂料的(de)(de)凝固(gu)劑、橡膠(jiao)行(xing)業(ye)乳膠(jiao)凝結(jie)劑、造(zao)紙工(gong)業(ye)添加劑及(ji)廢紙張脫墨(mo)、化(hua)(hua)學工(gong)業(ye)的(de)(de)無機化(hua)(hua)工(gong)原料及(ji)硫酸根(gen)脫除劑，工(gong)業(ye)鹽(yan)(yan)(yan)(yan)在工(gong)業(ye)上的(de)(de)用(yong)途很廣，它是(shi)外觀無色的(de)(de)立(li)方結(jie)晶(jing)或(huo)(huo)細小結(jie)晶(jing)粉(fen)末，易溶于(yu)水(shui)。用(yong)地下鹽(yan)(yan)(yan)(yan)水(shui)和井鹽(yan)(yan)(yan)(yan)為原料時(shi)，通過三(san)效或(huo)(huo)四(si)效蒸發濃縮，析出結(jie)晶(jing)，精制(zhi)(zhi)工(gong)業(ye)鹽(yan)(yan)(yan)(yan)多少錢一(yi)噸，離心分離制(zhi)(zhi)得工(gong)業(ye)鹽(yan)(yan)(yan)(yan)。

工(gong)(gong)(gong)業(ye)(ye)鹽(yan)在工(gong)(gong)(gong)業(ye)(ye)上(shang)的用(yong)途很廣(guang)，它是外觀無色的立方結晶或細小結晶粉末，易(yi)溶于水。用(yong)地下(xia)鹽(yan)水和(he)井(jing)鹽(yan)為原料(liao)(liao)時，通過三效或四效蒸發濃縮(suo)，析出(chu)結晶，離(li)心分離(li)制(zhi)得工(gong)(gong)(gong)業(ye)(ye)鹽(yan)。工(gong)(gong)(gong)業(ye)(ye)鹽(yan)在生活中用(yong)到(dao)的小妙招您了解多(duo)少？木質家具(ju)運用(yong)時間長了或許(xu)會有(you)蛀蟲(chong)，這時分用(yong)工(gong)(gong)(gong)業(ye)(ye)鹽(yan)水在家具(ju)表面擦擦，就可以(yi)防蛀蟲(chong)了；我們(men)知道化學行(xing)業(ye)(ye)上(shang)多(duo)種化學產(chan)(chan)品都(dou)是以(yi)工(gong)(gong)(gong)業(ye)(ye)鹽(yan)為原料(liao)(liao)生產(chan)(chan)的，不僅(jin)如此，工(gong)(gong)(gong)業(ye)(ye)鹽(yan)在其他行(xing)業(ye)(ye)上(shang)也都(dou)有(you)作用(yong)，那下(xia)面我們(men)就一(yi)起來探討(tao)一(yi)下(xia)工(gong)(gong)(gong)業(ye)(ye)鹽(yan)在化學工(gong)(gong)(gong)業(ye)(ye)上(shang)的作用(yong)。
