Daily chemical grade hydroxypropyl methylcellulose is a white or slightly yellowish powder that can be dissolved in a solvent mixed with cold water and organic matter to form a transparent viscous solution. The aqueous solution has surface activity, high transparency, strong stability, and dissolution in water is not affected by pH. Daily chemical grade hydroxypropyl

- August 10, 2020
The content and ratio of hydroxypropoxy and methoxy in HPMC can affect the water retention energy, water solubility, surface activity and gel temperature of the product. Generally speaking, products with high methoxy content and low hydroxypropoxy content have better water solubility and surface activity, and the gel temperature is relatively low. If the methoxy content

Common phenomenon of scraping putty powder: bubbles are generated during the construction process and after a period of time, the surface of the putty foams. 1. Reasons 1. The base is too rough and the speed of criticism is too fast; 2. The putty layer is too thick at one time, greater than 2.0mm; 3.

The phenomenon of efflorescence is: ordinary concrete is silicate. When it meets the air or water vapor in the wall, the silicate ion undergoes a hydrolysis reaction, and the generated hydroxide combines with metal ions to form a hydroxide with less solubility (the chemical nature is Alkaline). When the temperature rises, the water vapor evaporates

Hydroxypropyl methyl cellulose is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and non-toxic white powder that swells into a clear or slightly turbid colloidal solution in cold water. It has the characteristics of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption,
