1. Appearance: MC is white or white like fibrous or granular powder, without odor. Properties: MC is almost insoluble in anhydrous ethanol, ether and acetone. In 80~90>℃ hot water quickly dispersed, swelling, quickly dissolved after cooling, the aqueous solution in the room temperature is quite stable, high temperature can be gel, and the gel with the temperature of the solution can be converted to each other. It has excellent wettability, dispersibility, adhesiveness, thickening, emulsification, water retention and film formation, as well as impenetrability to grease. The film has excellent toughness, flexibility and transparency. It is non-ionic, compatible with other emulsifiers, but easy to salt out, and the solution is stable in the ph2-12 range. 3. Apparent density: 0.30-0.70g/cm3; density: about 1.3g/cm3. 4. Method of dissolution: MC> product is directly added to water, which will produce condensation and then dissolve, but the solution is slow and difficult. Below suggests three methods of dissolution, the user can according to the using situation, choose the most convenient method: 1. The hot water method: since the MC will not dissolve in hot water, thus the early MC can evenly dispersed in hot water, then cooled, two typical methods described as follows: 1) in the container in the requirement of hot water, and heated to about 70 ℃. The MC is gradually added under slow agitation. At first, the MC floats on the surface of water, and then a slurry is gradually formed. The slurry is cooled under agitation. 2). Add 1/3 or 2/3 water required in the container and heat to 70℃. Disperse MC according to the method of 1) to prepare hot water slurry; The remaining amount of cold or ice water is then added to the hot slurry and stirred to cool the mixture. Powder mixing method: MC powder particles are dispersed with equal or larger amounts of other powdered ingredients by dry mixing, and then dissolved with water, so that MC can be dissolved without condensation. 3. Organic solvent wetting method: MC is pre-dispersed or wetted with organic solvent, such as ethanol, ethylene glycol or oil, and then dissolved with water. Then MC can also be dissolved smoothly.
This product is widely used in building construction, building materials, dispersive coating, wallpaper paste, polymerization auxiliary agent, except paint agent, leather, ink, paper, etc. respectively used as thickening agent, adhesive, water retention agent, film forming agent, excipient. If be used as adhesive, thickening agent and water retention agent on building materials, be used as film forming agent and thickening agent on coating industry, apply in the field such as petroleum drilling and chemical industry of daily use also relatively extensive.
