Properties of oxidized starch: Oxidized starch is a kind of Modified Starch which is obtained by the action of starch and oxidant in acid, alkali and neutral medium to oxidize starch. Through oxidation, carboxyl functional groups are introduced into starch molecules, and to some extent, the degree of polymerization of starch macromolecules is reduced due to degradation. Therefore, oxidized starch is endowed with some unique properties, which can be widely used in textile, paper making, packaging, food and fine chemical industries. 
Oxidized starch parameters: Appearance: white or yellowish powder Viscosity mpa. S: 30-32 (provided according to customer requirements) Water content: ≤ 14% Thermal stability: ≥ 85 PH value: 6~8 Sodium chloride: ≤ 1% Carboxyl content%: ≤ 0.01-0.30 Fineness (passing rate of 100 target standard sieves)%: ≥ 99
Differentiation of oxidized starch:
1. Starch has few impurities and high purity 2. Good transparency 3. Strong viscosity and good film-forming property 4. Volatility test: about 0.2 5. Introduction of advanced equipment, at least 10 tons of powder at a time, good stability 6. Lower gelatinization temperature and use cost Application of oxidized starch: 1. In the paper industry, it is used as surface sizing agent, coating adhesive, wet cloth addition and corrugated board adhesive. The oxidized starch is mainly used as sizing agent and adhesive in paper industry, which can significantly improve the printing performance and printing effect of paper. 2. In the packaging industry, it can be used as the adhesive for paper products, which can be prepared in cold water. It has the characteristics of fast drying speed, good stiffness of cardboard, good freeze-thaw resistance, no moisture absorption, no efflorescence, strong adhesion, etc. It can be applied to manual single machine, veneer machine, glue machine, pipe rolling machine, paper barrel machine, etc. 3.In the textile industry, oxidized starch is used as sizing agent. The oxidized starch is easy to gelatinize, has good fluidity, is easy to penetrate into the fiber, has uniform sizing, and reduces the occurrence of starch spots. It is suitable for sizing chemical fiber, polyester cotton, polyester rayon and other varieties of light yarn. Storage mode: It is recommended to store in a dry and ventilated environment to avoid damp and mildew.
