Main specifications of
Pharmaceutical Grade: (Conforming to standard of USP 30) Item Index Methoxyl content:wt% 28.0-32.0 Loss on drying: wt% ≤5.0 Viscosity: map,s 5-100000 Ash content:wt% ≤1.0 Main specifications of Industral Grade Item Index Methoxyl content:wt% 28.0-32.0 Loss on drying: wt% ≤5.0 Viscosity: map,s 5-100000 Ash content:wt% ≤3.0 Gelation temperature:℃ 52-67 Notice: 55RT6000: “55” means the gelation temperature of MC, “6000” is the viscosity of the MC, “RT” is the first Chinese phonetic alprabets of the “RUITAI” Priorities Appearance: white or nearly white powder. Odorless and tasteless. MC is non-ionic water-soluble cellulose ether. It can be dissolved in water below 60℃ and alcohol 70% or acetone easily. True specific gravity:1.26~1.31, Bulk density:0.25-0.7g/cm3; Carbonization temperature: 225- 230℃. Main uses MC can be used as adhesive, densifiec, dispering agent. Emulsifying agent and can be used for film former and adhesire in coating material industry and. Used as adhesire and moisture retentive agent in construction industry, It has also wide application in the field of oil drilling daily chemical industry and others. Therefore, it is nonionic cellulose ether in brilliant prospects. Process for dissolving MC 1. Place the required amount of hot water heated to above 80℃. In a vessel. Add Mc gradually while stirring gently. At first MC floats on the surface of the water. But it is gradually dispersed to form a uniform slurry, cool the slurry while stirring it. 2. Place one –thirds of the required amount of water, heated to above dispersed to form a uniform slurry, cool the required amount of water heated to above 80℃. In a vessel, Disperse MC and prepare a hot water slurry in the same way as described in method (1), add the remaining amount of cold water to the hot slurry while stirring, cool the resultant mixture. Package, storage, transportation It is packed in knitting bag covered by plastic. Net weight 25kg. prevent from raining. And fire, wet must be avoided. |
