III. Physical and chemical properties
1. Appearance: White of off-white, odourless and tasteless powder,
Innoxious, light hydroscopicity.
2. Dissolution: It almost does not dissolve in ethanot, ethyl ether, chloroform, it can form clear and suspended viscous solution in the mixture of water and glacial acetic acid or the mixture of ethanol and chloroform (1: 1). It swell quickly
In the hot water of 80-90° C and dissolve quickly when the temperature drops, its aqueous soultion is quite stable at normal temperature, MC get formal by high temperature can display reverible change from get to solution in turn by heating and cooling. It has good humectant and dispersing, binding, chickening, emulsifying,
Water retention and film forming properties, film has excellent toughness, flexibility and clearance, Because of its non-ionic it can be compatible with other emulsifiers but easy to salt out, and show stable in the range of pH2-12.
3. Density: 1.3G/ cm3
4. Appearance: 0.25-0.7 g/ cm3
5. Temperature change to color: 190-200
6. Carbonation temperature: 225-250
IV. Application
The product is widely used in building construction, building material, dispersing coating, wall paper coating, polymerization aid, cosmetics, pharmaceuticals, varnish remover, food, leather, printing ink, paper and etc working as thickner, adhesive, moisture retentive agent, film former, excipient, emulsifier and so on. For example, it is used as adhesive, thickener and moisture retentive agent in building material; Film former and thickener in coating industry, Furthermore, it also has a wide use in oil drilling and daily chemical industry.
V. Dissolution method
Heat the required amount of water to 80-90. Add MC gradually while continuous stirring. The formed slurry can change to uniform aqueous solution after cooling, Or, add 1/3 to 2/3 of required hot water, then heat to 80-90. Add MC gradually while continuous stirring, Add the remaining ice water or ice when MC swells, Stir and cool it to form uniform aqueous solution.
VI. Packing, Storage and Transportation
Package: Plastics-paper bag outside, lined with PVC bag.
Storage: Seal tightly, Exposing to the sun and rain is forbidden, to avoid absorption of moisture and contact with acid and alkali
Transportation: As common moisture-proof chemical.
