Efficient acid NUA

Efficient acid NUA is a unique product that can quickly and completely neutralize the caustic soda bath to clean water. And acetic acid and different NUA, no remaining salt in the fiber, and these salt residues were turned into a buffer will affect the subsequent step of the process.

Performance characteristics

1、No volatility, no smell, does not affect the workshop production environment and worker health, and reduces VOs emissions of organic waste gas in the atmosphere.

2、It can quickly and completely neutralize the caustic soda, without generating residual bases on the fiber, and improve the quality of subsequent dyeing.

3、Pre-treatment and neutralization can save hot and cold water washing, energy saving and emission reduction, saving time.

4、COD and BOD values are 10 times less than acetic acid and citric acid, effectively reducing COD and BOD emissions from printing and dyeing wastewater.

5、Does not contain toxic chemicals and has good biodegradability.

Product character

Appearance：Colorless viscous liquid

Specific gravity：1.5

Solubility:Good water solubility

Reference dosage

Compared with other traditional products such as acetic acid, citric acid, formic acid, sulfuric acid, phosphoric acid or sulfamic acid, NUA has significant application advantages:

After bleaching with chlorine water:It neutralizes the caustic soda to a completely soluble salt and at the same time eliminates residual chlorides. Reduce the amount of bisulfite used in the chlorine removal process.

After bleaching with hydrogen peroxide:It neutralizes caustic soda to a completely soluble salt and eliminates residual chlorides at the same time. This salt will not revert back to the original alkali compound during storage.
