1.灘田法，夏季將含有氯化鈉、硫酸鈉、硫酸鎂、氯化鎂等成分的咸水灌入灘田，經(jīng)日曬蒸發(fā)，冬季析出粗芒硝。優(yōu)點(diǎn)：工藝簡(jiǎn)單，能耗低。缺點(diǎn)：易混入雜質(zhì)。 </p> <p> 2.機(jī)械冷凍法，利用機(jī)械設(shè)備將原料液加熱蒸發(fā)后冷凍至-5~-10℃時(shí)析出芒硝。優(yōu)點(diǎn)：不受季節(jié)影響，純度高。缺點(diǎn)：能耗高。 </p> <p> 3.鹽湖綜合利用法。 </p> <p> 灘田法和機(jī)械冷凍法適于加工以Na、Mg、Cl、SO4為主要成分的海水型鹽水及其他各種芒硝礦。因低溫下硫酸鈉的溶解度急劇變小，根據(jù)水鹽體系相平衡關(guān)系可以從鹵水中分離出粗芒硝。 </p> <p> <br />

因?yàn)槿玖显诩尤胨兄髸?huì)有一部分溶解在水中，所以會(huì)導(dǎo)致染棉不能很好地吸收，染布不容易上色。加入元明粉之后可以減小染料在水中的溶解度，從而增加染料的上色能力。這樣就會(huì)使得染料的用量減少而所染的顏色加深。 </p> <p> 二、元明粉可以用作直接染料染絲的緩染劑： </p> <p> 在印染絲綢的時(shí)候，加入元明粉會(huì)因?yàn)榘l(fā)生的化學(xué)反應(yīng)而影響鈉離子，因此會(huì)起到緩染的作用。 </p> <p> 三、在印染過(guò)程中加入元明粉會(huì)緩和色素酸的產(chǎn)生以及上色，從而使得染色更容易也更均勻。 </p> <p> 四、元明粉可以用作印染絲織物精煉時(shí)的地色保護(hù)劑； </p> <p> 在染色絲織物的時(shí)候染料可能會(huì)被剝落，會(huì)導(dǎo)致污染地色或是其他的同煉的織物，加入元明粉可以減小染料的溶解度，所以就不會(huì)產(chǎn)生染料剝落的現(xiàn)象了。 </p> <p> <br /> 元明粉在硫酸鹽鍍鋅中可用作緩沖劑以穩(wěn)定鍍液的ph值。南通特種大顆粒元明粉廠家直銷</p><p
