元明粉(也稱玄明粉、無水芒硝)化學(xué)成分是硫酸鈉，分子式：Na2SO4分子量：142.04。物化性質(zhì)：白色或淺黃色，顆粒結(jié)晶或粉末，有苦咸味，具有吸溫性。相對(duì)密度2.68，熔點(diǎn)884℃，溶于水，溶液呈堿性，不溶于乙醇。暴露于空氣中易吸濕變成為含水硫酸鈉。 </p> <p> 元明粉是一種基礎(chǔ)化工原料，廣泛應(yīng)用于化工生產(chǎn)的各行各業(yè)，如造紙工業(yè)中用硫酸鈉來補(bǔ)充制漿中堿和硫的損失;合成洗滌劑生產(chǎn)中添加約40%的硫酸鈉作為洗衣粉的載體;在染料工業(yè)中硫酸鈉是制造硫化鈉的主要原料。元明粉也可作為輕質(zhì)材料的摻合劑、水泥、混凝土的添加劑、有機(jī)化工產(chǎn)品的催化劑等，是眾多行業(yè)所必需的基礎(chǔ)化工原料，在國民經(jīng)濟(jì)的蓬勃發(fā)展過程中扮演著不可或缺地重要角色。生產(chǎn)元明粉的主要原料是芒硝礦。元明粉細(xì)粉超細(xì)粉是指以200目以上的顆粒狀存在的元明粉。河南工業(yè)級(jí)元明粉</p><p
