軟水鹽與工業(yè)鹽有何區別,為什么比工業(yè)鹽價(jià)格高
添加日期:2021-7-3    訪(fǎng)問(wèn) 4397 次   

軟水鹽雖然也是工業(yè)化生成的,但和我們常說(shuō)的“工業(yè)鹽”還是有著(zhù)本質(zhì)的區別,并且在價(jià)格的比較上,軟水鹽也是比工業(yè)鹽的價(jià)格要高的。

 

 

一、什么是軟水鹽?

我們知道,目前水處理的方法有很多種。但最主要、最先進(jìn)的水處理技術(shù)就是離子交換技術(shù)。

 

所謂離子交換,就是在水質(zhì)凈化器里面采用離子交換樹(shù)脂,通常為磺酸鹽型鈉離子交換樹(shù)脂。當需要處理的原水通過(guò)這種樹(shù)脂以后,就可以將水內的有害雜質(zhì)離子吸附于樹(shù)脂內,達到凈化水質(zhì)的目的。

 

而為了保持這種樹(shù)脂的活性,需要經(jīng)常清除雜質(zhì)再生樹(shù)脂,這就需要高質(zhì)量的鈉鹽片劑,以恢復離子交換樹(shù)脂的吸附功能。

 

這種軟化水所用的磺酸鹽型鈉離子交換樹(shù)脂的再生劑就叫軟水鹽。

 

軟水鹽的含氯化鈉濃度非常高。一般,軟水鹽的氯化鈉含量都大于99%??梢苑Q(chēng)為“純鹽”!

 

二、什么是工業(yè)鹽?

 

工業(yè)鹽,是化學(xué)工業(yè)的最基本原料之一,主要成分有氯化鈉、亞硝酸鈉等,被稱(chēng)為“化學(xué)工業(yè)之母”。

 

"工業(yè)鹽"通常習慣特指亞硝酸鹽。亞硝酸鹽還原性強,可以使肉色鮮艷,生活中部分不良無(wú)知商家用工業(yè)鹽腌制不新鮮肉制品,導致發(fā)生群體性亞硝酸鹽中毒事件。

 

人體長(cháng)期攝入亞硝酸鹽也有增加癌變風(fēng)險,工業(yè)鹽嚴禁食用。

 

工業(yè)鹽含氯化鈉的成分沒(méi)有軟水鹽那么純,一般在96%以下。

 

 

所以,從制鹽的工藝水平來(lái)說(shuō),軟水鹽相比工業(yè)鹽要求更高一些,所以在價(jià)格的體現上也就高一些了。
