How to simply and intuitively judge the quality of Hydroxypropyl methyl cellulose ether?

1) Observe the whiteness of Hydroxypropyl methyl cellulose ether: Although the whiteness cannot determine whether Hydroxypropyl methyl cellulose ether is easy to use, and if a brightener is added in the production process, its quality will be affected. However, most good products have good whiteness.

2) The fineness of Hydroxypropyl methyl cellulose ether: The fineness of HPMC is generally 80 mesh and 100 mesh, 120 mesh is less, the finer the finer, the better in general.

3) Transmittance of Hydroxypropyl methyl cellulose ether after dissolution: Put the hydroxypropyl methyl cellulose ether in water to form a transparent colloid, and look at its transmittance. The greater the transmittance, the better, indicating that there are less insolubles inside. . The permeability of the vertical reactor is generally good, and the horizontal reactor is worse, but it does not mean that the quality of the vertical reactor is better than that of the horizontal reactor. The product quality is still determined by many factors.

4) The specific gravity of Hydroxypropyl methyl cellulose ether: the larger the specific gravity, the heavier the better. The high specificity is generally due to the high hydroxypropyl content in it, and the higher the hydroxypropyl content, the better the water retention.

Hydroxypropyl methyl cellulose ether produced by MST for 20 years, has professional laboratories and researchers, and the technology is constantly updated. After the replacement, the Hydroxypropyl methyl cellulose ether has high water retention in the construction industry and improves the workability and adhesion of the mortar. And slip resistance. Not only occupy the main domestic market, but also export to Europe and Southeast Asian countries.
