High Quality HPS Starch Ether from China Suppliers - Trusted Factory for Superior Products
Product Overview
Starch ether is a class of products obtained by chemically modifying ether groups into starch molecules, and is usually a white or white-like powder.
Product Characteristics
- Thickening: Can significantly increase the viscosity of the system, improve the flow performance.
- Water retention: Effectively retain water and reduce water loss.
- Anti-slip: It can prevent the slip of the material in the building material.
- Good compatibility: Good compatibility with various building materials and additives.
Product Use
Architectural Field
- All kinds of dry mix mortar: such as tile glue, plastering mortar, thermal insulation mortar, etc., improve the construction performance and product quality.
- Putty: Enhances the batch scraping and crack resistance of putty.
Other Industries
- Ceramic industry: Used for ceramic paste to improve its fluidity and stability.
- Coating industry: Increase the viscosity and stability of coatings, prevent flow hanging.
Production Process
It is generally prepared by the reaction of starch and etherifying agent under specific conditions.
Market Prospects
With the increasing demand for high-performance materials in the construction industry, as well as the improvement of environmental protection and energy saving requirements, the application of starch ether in building materials is more and more extensive, and the market prospect is very broad.
Use Precautions
- Storage should be kept dry and ventilated to avoid moisture agglomeration.
- When using, the addition amount should be reasonably controlled according to the specific application scenario and formula requirements.
- Different types of starch ethers may have differences in performance and should be selected according to actual needs.
For example, in the application of ceramic tile glue, the appropriate addition of starch ether can improve the initial viscosity and anti-slip property of ceramic tile glue to ensure that the ceramic tile is firmly pasted; In putty, it can improve the constructability and crack resistance of putty.
In short, starch ether, as an excellent additive, plays an important role in many industries and provides an effective solution for improving product quality and performance.
