one、 Overview:
The company's reagent sulfuric acid production began inone thousand nine hundred and ninety-eightIn, it was a supporting project for the joint venture production of refined nickel sulfate with Great Wall company,one thousand nine hundred and ninety-nineIn, it began to increase production and sell products directly. All products are distilled in quartz glass containers and tested to meet national standardsGB6twofive-two thousand and sevenProducts. andfifty% analytical pure sulfuric acid is customized and obtained by diluting the national standard analytical pure sulfuric acid with deionized water.

4、 Precautions
one、Concentrated sulfuric acid is a highly corrosive liquid, so pay attention to safety when using it. The required protective equipment and rescue measures are the same as those of industrial products.
two、When packed in plastic containers, concentrated sulfuric acid will slowly dehydrate the plastic and turn black; Usually, sulfuric acid does not deteriorate, but it will break the plastic, so it should not be stored for a long time.
three、fifty%Analytical purity硫酸是为客户定制的安全型产品,系用去离子水稀释national standard试剂硫酸而得。
