Taizhou Sales Desalination, Deacidification and Decolorization Resin Telephone

Lactic acid is an important organic acid and has a wide range of uses. Especially with the development of PLA industry, the demand for lactic acid has increased significantly. The traditional production process of extracting lactic acid has low purity and high production cost. The use of lactic acid desalting and decoloring production technology to improve product quality and reduce production costs is an urgent need for the further development of China's lactic acid industry.

Macroporous strong acid styrene resin has excellent mechanical strength and permeability resistance. It is used for desalination, deionization, amino acid sugar and protein (H type) and calcium (Na type) of glucose solution. The gel strong acid styrene resin has high exchange capacity and is suitable for removing calcium from dilute sugar juice. Gel strong base styrene resin, highly porous gel strong base anion resin, used for decolorization and separation of organic aqueous solutions and drugs.

Acid solution regeneration

At ambient temperature, 4% HCL with a volume of 4 times of the resin bed is countercurrent through the resin bed for about half an hour.

Slow washing: at the same flow rate and flow direction, desalted water with the volume of 2 times the resin is supplied.

Quick washing: at the operating flow rate and flow direction, pass deionized water to PH=5-6. Resin bed for standby
