①. It has good water retention. Tiles do not need soaking treatment before pasting, can be used in construction for a longer time and smeared in large area; it has good adhesion effects, strong vertical flow resistance, and the construction can be from top to bottom.   ②. Since it has good workability, slide resistance,.. read more →

As an additive for cement mortar, the cellulose ether usually has an addition amount not more than 2% of cement mass. For the study on cellulose ether, there has been a long history of research abroad. For example, DOW had successfully developed and marketed as early as 1938. First, the higher viscosity the cellulose ether.. read more →

Effects of Cement Slurry with the Addition of Cellulose Ethers on Ceramic Tile Bonding   Abstract: In the cement mortar, add different kinds of cellulose ethers to make the bonding paste. This paper studies the effects of the dosage for different kinds of cellulose ethers and the open time of slurry on the shear strength.. read more →

Water retention is an important property of cellulose ether. The factors affecting the water retention effects of dry-mixed mortar include the addition amount, viscosity, fineness, the temperature of use environment of mortar.   Effects of the Addition Amount of Cellulose Ether on Water Retention When the addition amount of cellulose ether is within the range.. read more →

The cellulose ether and cellulose derivative are a large category of additives, usually powdery (or granular), and a few slurry (the suspensions formed when cellulose esters do not dissolve). Despite the competition against synthetic rheological modifiers, the cellulose derivative is still the main force of “thickening agents”, and mainly used for the production of various.. read more →

Cellulose ether is a major additive in the dry-mix mortar. Although the addition amount is very low, it can significantly improve the performance of mortar. It can improve the consistency, working performance, bonding properties and water retention properties of mortar, and plays a very important role in the field of dry-mix mortar. Its main features.. read more →

According to the ionization performance of substituents, cellulose ethers can also be divided into ionic and non-ionic types. The ionic type mainly includes carboxymethyl cellulose salt (CMC), while the non-ionic type includes methyl cellulose, methyl hydroxyethyl cellulose ether (MHEC), methyl hydroxypropyl cellulose ether (MHPC), and hydroxyethyl cellulose ether. Since the ionic cellulose (carboxymethyl cellulose salt).. read more →

Cellulose ether is the powdered cellulose ether generated with wood fiber or refined short cotton fiber as the main raw materials, after chemical treatment and by the reaction of etherifying agents such as chlorinated ethylene, chlorinated propylene and oxidized ethylene. The production process of cellulose ether is complex. It starts with the extraction of cellulose.. read more →
