At present, the more widely used water-reducing agents are lignin-basedwater-reducing agents naphthalene-based superplasticizers, melamine-based superplasticizers and polycarboxylate-based superplasticizers. And their characteristics are as follows: Lignin-basedWater-reducing Agents Lignin-basedwater-reducing agents have lignin sulfonates as the major components, including calcium lignosulphonate, sodium lignosulphonate and magnesiumlignosulphonate, and are ordinary water-reducing agents. They do not have high water-reducing rate, and.. 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 →
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 →
