1、 Overview:
In March 2001, the reagent workshop of Dongguan factory was officially put into operation, and the output of reagent hydrochloric acid was 10 tons per month. All products are distilled in quartz glass containers and tested to meet the national standard gb622-89.
2、 Quality standard:
Molecular formula HCl, molecular weight 36.46.
Project level | Chemically pure | Analytical purity |
HCl content | 36—38% | 36—38% |
appearance | Water clear | Water clear |
Burning residue ≤ | 0.002% | 0.0005% |
Free matter (calculated by Cl2) ≤ | 0.0002% | 0.0001% |
Sulfate (SO4) ≤ | 0.0005% | 0.0002% |
Sulfite (SO3) ≤ | 0.0002% | 0.0001% |
Iron (FE) ≤ | 0.0001% | 0.00005% |
Tin (SN) ≤ | 0.0002% | 0.0001% |
Heavy metal (calculated by Pb) ≤ | 0.00005% | 0.00002% |
Copper (Cu) ≤ | 0.0001% | 0.00001% |
Arsenic (as) ≤ | 0.00001% | 0.000005% |
3、 Packaging and storage:
Twelve months from the date of packingThe company can provide customers with the following packaged reagent hydrochloric acid:
1. 500ml glass bottles, 12 bottles per box.
2. 2.5L glass bottles, 2.5L plastic bottles, four bottles per box.
3. 20kg, 25kg 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. Hydrochloric 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.
When packed in plastic containers, hydrochloric acid will slowly dehydrate the plastic and turn yellow; Generally, hydrochloric acid does not deteriorate, but it will make the plastic broken and ugly, so it should not be stored for a long time.
