工业盐在轻工业中扮演什么角色

编辑:山东合展化工有限公司时间:2022-11-15

  工(gong)(gong)业盐(yan)是指原盐(yan)。原盐(yan)可分为湖(hu)盐(yan)、井盐(yan)和海盐(yan)。由于海盐(yan)中的海水溶(rong)解多(duo)种(zhong)元素,海盐(yan)的工(gong)(gong)业价(jia)值(zhi)相对较高,食用(yong)价(jia)值(zhi)较低。工(gong)(gong)业盐(yan)价(jia)格(ge)受此应用(yong)的影响,那么工(gong)(gong)业盐(yan)在轻(qing)工(gong)(gong)业中扮演什么角(jiao)色?

  1.精(jing)制(zhi)工业(ye)盐(yan)(yan)在机(ji)械工业(ye)中的(de)应(ying)用(yong)(yong):在铸(zhu)造过程(cheng)中,精(jing)制(zhi)工业(ye)盐(yan)(yan)可作为有(you)色(se)金(jin)属(shu)和(he)合金(jin)铸(zhu)件(jian)中砂的(de)优良粘合剂。在高(gao)温下,盐(yan)(yan)使铸(zhu)件(jian)型芯变软(ruan),从而防止(zhi)铸(zhu)件(jian)出现(xian)热(re)裂纹。与有(you)机(ji)粘结剂相比(bi),盐(yan)(yan)在高(gao)温下产生的(de)有(you)害气体少。当钢制(zhi)机(ji)械零件(jian)或工具进行热(re)处(chu)理时,常用(yong)(yong)的(de)加(jia)(jia)热(re)设备(bei)是盐(yan)(yan)浴炉(lu)。与箱(xiang)式炉(lu)相比(bi),盐(yan)(yan)浴炉(lu)具有(you)温度控制(zhi)容易、加(jia)(jia)热(re)均匀、加(jia)(jia)热(re)速度快、局部加(jia)(jia)热(re)、细长工件(jian)不易弯曲、避免氧化(hua)脱碳等优点,同时可作为渗碳化(hua)学热(re)处(chu)理的(de)常用(yong)(yong)催化(hua)剂。在热(re)处(chu)理过程(cheng)中,用(yong)(yong)盐(yan)(yan)水淬火也(ye)能获得理想的(de)效果(guo)。电(dian)镀前(qian),黑色(se)金(jin)属(shu)、铜和(he)铜合金(jin)的(de)强酸清洗需(xu)要盐(yan)(yan)。

  2.石(shi)油(you)工(gong)业应(ying)用(yong)(yong):在(zai)油(you)井(jing)(jing)钻井(jing)(jing)过程中(zhong)(zhong),为(wei)(wei)(wei)了保护岩盐(yan)(yan)(yan)层(ceng)岩芯的(de)(de)(de)(de)完整性(xing)(xing),需要在(zai)泥(ni)浆(jiang)中(zhong)(zhong)加入(ru)精(jing)制(zhi)(zhi)工(gong)业盐(yan)(yan)(yan)作(zuo)(zuo)(zuo)为(wei)(wei)(wei)稳定剂(ji),并使用(yong)(yong)盐(yan)(yan)(yan)化(hua)(hua)工(gong)产(chan)品(pin)硫酸(suan)钡增加钻井(jing)(jing)泥(ni)浆(jiang)的(de)(de)(de)(de)重(zhong)量和(he)作(zuo)(zuo)(zuo)为(wei)(wei)(wei)调节(jie)剂(ji)。在(zai)石(shi)油(you)精(jing)炼中(zhong)(zhong),盐(yan)(yan)(yan)被用(yong)(yong)作(zuo)(zuo)(zuo)脱水剂(ji),以去除汽油(you)中(zhong)(zhong)的(de)(de)(de)(de)水雾。在(zai)煤油(you)精(jing)制(zhi)(zhi)过程中(zhong)(zhong),用(yong)(yong)盐(yan)(yan)(yan)作(zuo)(zuo)(zuo)为(wei)(wei)(wei)过滤层(ceng)去除杂(za)质。许多盐(yan)(yan)(yan)化(hua)(hua)工(gong)产(chan)品(pin)也广泛用(yong)(yong)于石(shi)油(you)工(gong)业。例(li)如,一些油(you)溶性(xing)(xing)有机酸(suan)钡盐(yan)(yan)(yan)可以用(yong)(yong)作(zuo)(zuo)(zuo)汽油(you)燃(ran)(ran)烧的(de)(de)(de)(de)促(cu)进(jin)剂(ji),以促(cu)进(jin)汽油(you)的(de)(de)(de)(de)完全燃(ran)(ran)烧;燃(ran)(ran)料油(you)中(zhong)(zhong)可添加氧(yang)化(hua)(hua)镁(mei)、氢(qing)氧(yang)化(hua)(hua)镁(mei)和(he)碳酸(suan)镁(mei)作(zuo)(zuo)(zuo)为(wei)(wei)(wei)灰分改性(xing)(xing)剂(ji),以防止(zhi)钒(fan)化(hua)(hua)合物的(de)(de)(de)(de)高(gao)温腐蚀;以硼为(wei)(wei)(wei)原料制(zhi)(zhi)备(bei)的(de)(de)(de)(de)氮化(hua)(hua)硼具有与金(jin)刚石(shi)相同(tong)的(de)(de)(de)(de)硬度(du),在(zai)1500-1600℃高(gao)温下(xia)的(de)(de)(de)(de)稳定性(xing)(xing)优于金(jin)刚石(shi)。可作(zuo)(zuo)(zuo)为(wei)(wei)(wei)超硬材料用(yong)(yong)于生产(chan)石(shi)油(you)钻井(jing)(jing)用(yong)(yong)钻头,该产(chan)品(pin)应(ying)用(yong)(yong)如此广泛,因(yin)此工(gong)业盐(yan)(yan)(yan)价(jia)格也相对较高(gao)。

  3.轻工(gong)业(ye)(ye)(ye)应(ying)用(yong)(yong):在(zai)(zai)制(zhi)(zhi)皂过程(cheng)中(zhong),经常(chang)(chang)(chang)添加盐(yan)以(yi)保持(chi)溶液(ye)(ye)的(de)(de)适当粘度(du)(du)。由于盐(yan)中(zhong)钠(na)(na)(na)离子(zi)的(de)(de)作用(yong)(yong),皂化(hua)(hua)溶液(ye)(ye)的(de)(de)粘度(du)(du)可以(yi)降低,皂化(hua)(hua)反应(ying)可以(yi)正常(chang)(chang)(chang)进行(xing)。为(wei)(wei)了(le)使脂肪酸(suan)钠(na)(na)(na)在(zai)(zai)溶液(ye)(ye)中(zhong)达到(dao)足够(gou)的(de)(de)浓(nong)度(du)(du),应(ying)加入固体盐(yan)或(huo)浓(nong)盐(yan)水(shui)进行(xing)盐(yan)析,并提取甘油。在(zai)(zai)肥皂和(he)(he)合成洗涤剂中(zhong),也(ye)使用(yong)(yong)盐(yan)化(hua)(hua)工(gong)产(chan)品硅酸(suan)钠(na)(na)(na)作为(wei)(wei)填料,它可以(yi)增加肥皂的(de)(de)碱(jian)度(du)(du)、硬度(du)(du)和(he)(he)强(qiang)度(du)(du)。皮(pi)(pi)(pi)革工(gong)业(ye)(ye)(ye)需(xu)要(yao)大量的(de)(de)兽皮(pi)(pi)(pi)。在(zai)(zai)生(sheng)皮(pi)(pi)(pi)的(de)(de)储存(cun)和(he)(he)运输过程(cheng)中(zhong),为(wei)(wei)了(le)防(fang)止或(huo)减少(shao)微生(sheng)物的(de)(de)侵蚀,需(xu)要(yao)进行(xing)防(fang)腐(fu)处理,以(yi)避免降低生(sheng)皮(pi)(pi)(pi)的(de)(de)质量。皮(pi)(pi)(pi)革工(gong)业(ye)(ye)(ye)中(zhong)常(chang)(chang)(chang)用(yong)(yong)的(de)(de)防(fang)腐(fu)方法(fa)是盐(yan)渍和(he)(he)盐(yan)干。在(zai)(zai)鞣制(zhi)(zhi)过程(cheng)中(zhong),裸露(lu)的(de)(de)皮(pi)(pi)(pi)肤需(xu)要(yao)浸泡在(zai)(zai)酸(suan)洗溶液(ye)(ye)中(zhong),盐(yan)也(ye)是必(bi)不可少(shao)的(de)(de)。盐(yan)化(hua)(hua)工(gong)产(chan)品如(ru)硫(liu)(liu)化(hua)(hua)钠(na)(na)(na)、硫(liu)(liu)化(hua)(hua)氢钠(na)(na)(na)和(he)(he)硫(liu)(liu)代硫(liu)(liu)酸(suan)钠(na)(na)(na)用(yong)(yong)于生(sheng)皮(pi)(pi)(pi)脱毛和(he)(he)皮(pi)(pi)(pi)革鞣制(zhi)(zhi)。在(zai)(zai)造纸工(gong)业(ye)(ye)(ye)中(zhong),硫(liu)(liu)酸(suan)钠(na)(na)(na)、硫(liu)(liu)酸(suan)镁、氯酸(suan)钠(na)(na)(na)和(he)(he)其他盐(yan)化(hua)(hua)工(gong)产(chan)品用(yong)(yong)于制(zhi)(zhi)造纸浆、漂(piao)白(bai)浆和(he)(he)用(yong)(yong)作填料。各(ge)种盐(yan)化(hua)(hua)工(gong)产(chan)品也(ye)广泛应(ying)用(yong)(yong)于火柴、火药、印(yin)刷、电影和(he)(he)摄影行(xing)业(ye)(ye)(ye)。
