Starch ethers are used in cement-based systems such as plastering, adhesives, and leveling layer to form functional surfaces both internally and externally. Plastering mortar is used to cover uneven parts of walls. They must have a strong and durable bond to the substrate. The surface of the mortar must become smooth and flat in order to give uniform absorption and good.. read more →

A. The rheology properties of starch ether in machine and spray mortar Starch ethers prevent sagging of mortar and enhance pumping properties. They are easy to distribute evenly in mortar because they are of low viscosity, can dissolve fast, change the rheology of the plaster and gave it thixotropy. This shows that when the external force.. read more →

Hydroxypropyl Methyl Cellulose Ether (HPMC) are referred to as Methyl Cellulose ether (MC). MC is one of the most important additives in dry powder mortar which mainly plays the role of water retention and thickening.   MC is a kind of powdered cellulose ether made of wood fiber or refined short cotton fiber as the main.. read more →

A fiber is a cell which is a typical dead plant cell with two pointed ends, thick skin, and void in the middle. The fibers (cells) are characterized by being thin and long, with spindle-like ends, flexible, and have a certain binding force with each other after interweaving. The fiber cell is empty inside and surrounded by the cell wall which is composed.. read more →

Viscosity There are different types of viscometers used to measure the viscosity of a cellulose ether solution. The widely adopted viscometers are: HoppIer falling ball viscometer, Haake rotation Rheometer and Brookfield rotation viscometer. The viscometer commonly used in China is NDJ series. The viscometers adopted by different cellulose ether manufacturers are different in the market. With the same solution, testing in different viscometers,.. read more →
