What is the effect of “tackifier” on cellulose ether in mortar?
Cellulose ether, especially hydroxypropyl methylcellulose ether (HPMC) is an important component in commercial mortar. For cellulose ether, its viscosity is an important indicator that mortar manufacturers pay attention to, and high viscosity has almost become the basic demand of the mortar indus...Read more -
What are the structures and types of cellulose ethers?
1.Structure and preparation principle of cellulose ether Figure 1 shows the typical structure of cellulose ethers. Each b-D-anhydroglucose unit (the repeating unit of cellulose) replaces one group at the C (2), C (3) and C (6) positions, that is, there can be up to three ether groups. Due to the ...Read more -
The quality of cellulose ether determines the quality of mortar
In ready-mixed mortar, the addition amount of cellulose ether is very low, but it can significantly improve the performance of wet mortar, and it is a main additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different visc...Read more -

How is sodium carboxymethylcellulose prepared?
Using cellulose as raw material, CMC-Na was prepared by a two-step method. The first is the alkalization process of cellulose. The cellulose reacts with sodium hydroxide to generate alkali cellulose, and then the alkali cellulose reacts with chloroacetic acid to generate CMC-Na, which is called e...Read more -
