1、 Overview:

The company's production of reagent sulfuric acid began in 1998. It is a supporting project for the joint venture production of refined nickel sulfate with Great Wall company. In 1999, the company began to increase production and sell products directly. All products are distilled in quartz glass containers and tested to meet the national standard gb625-89.

In March 2001, the reagent sulfuric acid project of Dongguan factory was officially put into operation, and the reagent sulfuric acid available for sale will increase to 100 tons per month. It is planned to increase the total output to 200 tons per month by the end of 2002.

3、 Packaging and storage:

The company can provide customers with bulk water and the following packaged reagent sulfuric acid:
1. 500ml glass bottles, 12 bottles per box.
2. 2.5L plastic bottles, 4 bottles per box.
3. 25, 30, 35, 40 kg plastic drums.
4. Other packaging required by customers or self-contained packaging.
Validity: two years for glass bottles and three months for plastic containers.

4、 Precautions:
1. 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.
2. When packed in plastic containers, 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.
3、50%Analytical purity硫酸是專為東莞希普勵(lì)配制的安全型產(chǎn)品。該產(chǎn)品在稀釋過(guò)程中不會(huì)發(fā)熱。
