OXIDISEDSTARCH - Physico-chemical Properties
| Appearance | White powder |
| PH | 6.0~8.0 |
| Storage Condition | 置于干燥的库房内。远离火源。 |
| Physical and Chemical Properties | White powder. It is characterized by low gelatinization temperature, good transparency and stability of paste, and not easy to set down. |
| Use | Used in the papermaking industry as a thickener and sizing agent with low viscosity and high concentration. Weak coagulation, good water absorption and molding properties, strong adhesion, low viscosity, and belongs to anionic properties. Commonly used as a surface adhesive and coating adhesive. |
| Caution | Non hazardous materials. Avoid contact with skin and eyes. If accidentally splashed into the eyes, lift the eyelids and rinse with flowing water or physiological saline. |
OXIDISEDSTARCH - Preparation method
Open Data Verified Data
Mix starch into 33%~44% starch slurry and add it to the reactor. Under stirring, add NaOH solution dropwise for oxidation. Stir at 35-40 ℃ for 30 minutes. After the reaction is complete, neutralize with dilute hydrochloric acid to a pH value of 6.0-6.5, and add Na2SO3 to remove free chlorine. The finished product is obtained by washing, filtering, drying, and packaging.
