1. Hydroxyethyl cellulose is a natural polymer, each fibrous ring ring contains three hydroxyl groups, the most active hydroxyl reaction, the formation of hydroxyethyl cellulose. The raw cotton linter or refined pulp is soaked in 30% of the liquid base and the press is removed after half an hour. Crushed Read more…
Anti-dispersibility is an important measure of the quality of anti-dispersant. HPMC is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer, by increasing the viscosity of the mixed water to increase the consistency of the mixture, is a hydrophilic polymer material, dissolved in water to form a Read more…
The base cellulose is first prepared and then reacted with an etherifying agent And the remaining base, the product is isolated and purified, dried and pulverized to obtain the product. In general, when the HPC is prepared by the slurry technique, the alkali cellulose is generally powdered or pulverized Cotton Read more…
A drilling-fluid additive used primarily for fluid-loss control, manufactured by reacting natural cellulose with monochloroacetic acid and sodium hydroxide[NaOH] to form CMC sodium salt. Up to 20 wt % of CMC may be NaCl, a by-product of manufacture, but purified grades of CMC contain only small amounts of NaCl. To Read more…
1.act as the binder and play a bonding role. It can increase the strength of raw glaze, reduce the drying shrinkage of glaze, make the green body and the glaze firmly combined and not easy to fall off, be easy for process operation, and prevent such defects as rolling and Read more…
