Ⅲ. physical and chemical properties
Physical state granular solid
Color white to off-white
Odor slight
Specific gravity heavier than water
Vapor pressure negligible at 20℃
Solubility in water insoluble at temperatures above 45℃(113℉)
PH ＆#118alue 5-8.5 (in water solution)
Charing temperature 280-300℃
Browning temperature 190-200℃
Softening point 212-302℉
Ⅳ.Specialized Cellulose for Building Materials industry
Expression of product specification
55. 60.65.75 1000 S. Q. M
55.60.65.75 : Gelling Temperature of Produces
1000:Viscosity specification of products
S: surface treatment Type products (Dissolution Delaying)
Q: Quick dissolving products
M: Character Modified products
Solution Preparation
Products without surface treatment have infusibility in hot water ,It can be wet in hot water 85℃ or above, but to make it totally dissolved, the solution must be cooled to 20℃-25℃to get ideal transparency and viscosity ;otherwise, if it is added in cold water without totally wet, it will rapidly agglomerate and cause not exactly dissolution.
Products after surface treatment (S type) can be added in cold water directly and dispersed rapidly by stiring and dissolved to ideal viscosity in alkalescency state (PH 8-9) .
Quick dissolving products (Q type) can be added in cold water directly and dissolved by stirring for viscosity without adjusting PH ＆#118alue.
Character modified products (M type) normally use dry mixing and dispersing .By dry mixing before adding water, large numbers of powder ensures that cellulose ether granules are evenly dispersed, then adding water, and its dispersing time , hardening time and sticking strength will be modified because of its multi-group additives.
