Yellow dextrin is an important product which is widely used in many industries. The following is a detailed product introduction of yellow dextrin:

1. basic information

Name: yellow dextrin

Appearance: yellow white powder, high purity

Solubility: Soluble in water, forming a highly viscous solution, but insoluble in alcohol and ether

Main nature of 2.

Chemical stability: Yellow dextrin is a non-ionic water-soluble polymer with excellent physical properties and chemical stability.

Viscosity and fluidity: yellow dextrin has moderate viscosity, good fluidity, and conforms to the nature of Newtonian fluids.

3. preparation process

Yellow dextrins are mainly obtained by incomplete hydrolysis of starch under acid or heat treatment. The preparation process involves hydrolysis reaction, glycoside bond transfer and repolymerization reaction. Specifically, hydrochloric acid and water are mixed in a certain proportion and then sprayed on the starch, stirred evenly and then heated to make the starch molecules undergo hydrolysis and repolymerization reaction, and finally yellow dextrin is obtained.

4. Application Areas

Because of its unique physical and chemical properties, yellow dextrin has a wide range of applications in many industries:

Abrasives: In the abrasive industry, yellow dextrin is used as a binder to help the initial setting of the product, prevent collapse, and keep the angle and stare blankly.

Foundry: In the foundry industry, yellow dextrin can play a smooth role, and the use of oil binder can improve the wet strength and avoid deformation.

Refractory materials: In the production of refractory materials and light bricks, special-shaped bricks and other products, yellow dextrin has an excellent effect on the initial setting of the product, which can significantly improve the quality and performance of the product.

Rubber products: In the rubber products industry, yellow dextrin is used as a binder or thickener to help improve the processing performance of rubber products and the performance of the final product.

Other areas: yellow dextrin is also widely used in the textile printing and dyeing industry, pigment thickener, pharmaceutical microencapsulation agent, paper industry coating machine and other fields.

5. considerations

When using yellow dextrin, it is necessary to pay attention to its moderate dosage, too much may lead to too viscous mortar, affecting the construction effect.

At the same time, it is also necessary to pay attention to the compatibility of yellow dextrin with other additives to avoid chemical reactions affecting performance.

In summary, yellow dextrin is a product that has important applications in multiple industries, and its unique physical and chemical properties make it an integral part of many industrial processes.
