因為染料在加入水中之后會有一部分溶解在水中，所以會導(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> 在印染絲綢的時候，加入元明粉會因為發(fā)生的化學(xué)反應(yīng)而影響鈉離子，因此會起到緩染的作用。 </p> <p> 三、在印染過程中加入元明粉會緩和色素酸的產(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的地色保護劑； </p> <p> 在染色絲織物的時候染料可能會被剝落，會導(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，所以就不會產(chǎn)生染料剝落的現(xiàn)象了。 </p> <p> <br /> </p><p style="text-indent:25px">元明粉的生產(chǎn)工藝，包括以下步驟(1)原硝水提純原硝水經(jīng)靜置，取上清液經(jīng)過砂濾裝置過濾得到精硝水，取下濁液經(jīng)過轉(zhuǎn)鼓真空過濾器后在經(jīng)過砂濾裝置得到精硝水；(2)精硝水提純精硝水經(jīng)過生物膜活性炭過濾后，然后再經(jīng)過納濾膜處理，取納濾膜處理得到的廢水；(3)重結(jié)晶將廢水干燥、結(jié)晶，然后通過離心處理，干燥得到元明粉晶種，將元明粉晶種重結(jié)晶，得到元明粉；(4)元明粉改性向元明粉中加入表面活性劑，經(jīng)過球磨、加熱、冷卻得到改性元明粉。本發(fā)明提供的元明粉的生產(chǎn)工藝，能夠減少環(huán)境污染、元明粉產(chǎn)率高，原硝水浪費少，產(chǎn)出的元明粉純度高，元明粉的純度可達到99.8％。無水硫酸鈉:玻璃工業(yè)用以代替純堿做助溶劑。</p><div

控制無水硫酸鈉結(jié)塊的措施無水硫酸鈉是我們常用的一種化工產(chǎn)品，這個產(chǎn)品在應(yīng)用方面也比較廣，那么在使用的時候我們也有很多注意事項，那么如何控制這個產(chǎn)品結(jié)塊呢？下面山東合展化工有限公司為大家介紹一下這個以防結(jié)塊的措施，希望我們分享的內(nèi)容能幫到您！1）增加產(chǎn)品的粒徑，降低顆粒間的接觸點。根據(jù)結(jié)晶理論，過飽和度與晶粒尺寸的關(guān)系如下：LNs=LNC′/LNC=2δM/ρRTR=（2δM/ρRT）·（1/R）由過飽和度的數(shù)學(xué)表達式可知，在適宜溫度下，δ、M、ρ、R、T5為常數(shù)，晶核的粒徑為只與溶液的過飽和度有關(guān)，與溶液的過飽和度成反比，即溶液的過飽和度越小，晶體尺寸越大。（一）控制無水硫酸鈉適當(dāng)?shù)募訜嵴羝麎毫退男д舭l(fā)室的真空度。如果蒸汽壓力和真空度過高，可以實現(xiàn)安全生產(chǎn)，而且蒸發(fā)速度快，蒸發(fā)液會過飽和，形成細晶。一效加熱蒸汽的蒸汽壓力應(yīng)控制在，四效蒸發(fā)室的真空度應(yīng)為。（二）控制溶液蒸發(fā)過程中添加適宜的量。洗槽后，作用都是脫硝液。此時應(yīng)加入晶種，用量為。添加母液時，由于母液中結(jié)晶顆粒較多，要停止添加產(chǎn)品。嚴格控制母液配比，保持清洗液與母液的比例為（2-3）∶1，以免蒸發(fā)液中結(jié)晶核過多而形成細小顆粒。（三）制作蒸發(fā)器時。元明粉，白色、無臭、有苦味的結(jié)晶或粉末，有吸濕性。山東超細元明粉品牌</p><p

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：工藝簡單，能耗低。缺點：易混入雜質(zhì)。 </p> <p> 2.機械冷凍法，利用機械設(shè)備將原料液加熱蒸發(fā)后冷凍至-5~-10℃時析出芒硝。優(yōu)點：不受季節(jié)影響，純度高。缺點：能耗高。 </p> <p> 3.鹽湖綜合利用法。 </p> <p> 灘田法和機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 /> 江蘇工業(yè)級超細元明粉生產(chǎn)廠家</p><p
