Main Applications:

1. As a textile auxiliary, it is used as an acidifying agent for fibers and their products during dyeing or printing processes.

2. Due to its easy hydrolysis, it can replace commonly used organic acids (such as citric acid and acetic acid) to smoothly regulate the pH of the dye bath, improve dye uptake, enhance dyeability, and reduce dye consumption. It also eliminates the irritating odors produced by organic acidifying agents and potential damage to dyed fibers or fabrics.

3. It can also be used as a solvent (azeotropic agent) for separating aromatic hydrocarbons from alkanes, and as a plasticizer for polymers.

4. It is also used in self-hardening sodium silicate composite materials.

 

Packaging and Storage:

1. Available in 50KG or 200KG plastic drums. Handle with care during transportation.
