PAC(Polyanaionic Cellulose), which is a water-soluble cellulose ether derivative prepared by chemical modification of natural cellulose. It is an important water-soluble cellulose ether. It is usually used in its sodium salt and is widely used in petroleum Drilling, especially salt water wells and offshore oil drilling. Polyanionic cellulose is widely used and can be used […]
Preparation of Hydroxypropyl Methyl Cellulose
June 11, 2017 by
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 as raw material, dispersed in […]
Hydroxyethyl Cellulose Production Process

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 to alkali water containing 1: […]

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 solution Or dispersion. It can […]

Sodium Carboxymethyl Cellulose Used in Oil and Gas Drilling
June 11, 2017 by
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 make CMC, OH groups on […]
Sodium Carboxymethyl Cellulose Used in Ceramics

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 missing of glaze. While playing […]
sodium carboxymethyl cellulose pharmaceutical uses
June 11, 2017 by
Sodium Carboxymethyl cellulose appears as white, fibrous, free-flowing powder, and is used commonly as an FDA-approved disintegrant in pharmaceutical manufacturing. Disintegrants facilitate the breakup of a tablet in the intestinal tract after oral administration. Without a disintegrant, tablets may not dissolve appropriately and may effect the amount of active ingredient absorbed, thereby decreasing effectiveness. Polymers […]
Sodium Carboxymethy Cellulose Used in Food Industry
June 10, 2017 by
FAO and WHO have agreed to use pure sodium carboxymethylcellulose sodium cc for food, which is subject to very stringent biology, toxicology research and experimental consent, the international standard safe intake (ADI) is 25mg / (Kg · d), that is about 1.5 g / d per person. It has been reported that some people had […]
Guidance for Making Sodium Carboxymethyl Cellulose Solution
June 10, 2017 by
Food Additives Sodium carboxymethyl starch is everywhere in the food industry. Food additives are modern food industry products, no food additives, food can not be as colorful as it is now. Reasonable and legitimate use of food additives, will not affect food safety. Green, natural is now a lot of people choose an important basis […]
