控制無水硫酸鈉結塊的措施無水硫酸鈉是我們常用的一種化工產品，這個產品在應用方面也比較廣，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品結塊呢？下面山東合展化工有限公司為大家介紹一下這個以防結塊的措施，希望我們分享的內容能幫到您！1）增加產品的粒徑，降低顆粒間的接觸點。根據結晶理論，過飽和度與晶粒尺寸的關系如下：LNs=LNC′/LNC=2δM/ρRTR=（2δM/ρRT）·（1/R）由過飽和度的數學表達式可知，在適宜溫度下，δ、M、ρ、R、T5為常數，晶核的粒徑為只與溶液的過飽和度有關，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的加熱蒸汽壓力和四效蒸發(fā)室的真空度。如果蒸汽壓力和真空度過高，可以實現安全生產，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控制在，四效蒸發(fā)室的真空度應為。（二）控制溶液蒸發(fā)過程中添加適宜的量。洗槽后，浙江化工元明粉批發(fā)價格，作用都是脫硝液。此時應加入晶種，用量為，浙江化工元明粉批發(fā)價格。添加母液時，由于母液中結晶顆粒較多，要停止添加產品，浙江化工元明粉批發(fā)價格。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)液中結晶核過多而形成細小顆粒。（三）制作蒸發(fā)器時。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。浙江化工元明粉批發(fā)價格</p><div
