Solution Preparation
1    Products without surface treatment have infusibility in hot water. It can be wet in hot water of 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 non-total dissolution.
2    Products after surface treatment (S type) can be added in cold water directly and dispersed rapidly by stirring and dissolved to ideal viscosity in alkalescency state (PH 8-9).
3    Quick dissolving products (Q type) can be added in cold water directly and dissolve by stirring for viscosity without adjusting PH value.
4    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.
