Precautions for use
Since the surface-treated hydroxyethyl cellulose is in powder or cellulose solid, it is easy to operate and dissolve it in water as long as the following matters are noted.
1. Before and after adding hydroxyethyl cellulose, it must be stirred continuously until the solution is completely transparent and clear.
2. It must be sifted into the mixing barrel slowly. Do not add large quantities or hydroxyethyl cellulose that has formed blocks and spheres directly into the mixing barrel.
3. The water temperature and the pH value in the water have a significant relationship with the dissolution of hydroxyethyl cellulose, so special attention must be paid.
4. Never add some alkaline substances to the mixture before the hydroxyethyl cellulose powder is heated thoroughly by the water. Increasing the pH value after heating thoroughly will help dissolution.
5. Add mildew inhibitors as early as possible.
6. When using high-viscosity hydroxyethyl cellulose, the concentration of the mother liquor should not be higher than 2.5-3%, otherwise the mother liquor will be difficult to operate. Post-treated hydroxyethyl cellulose is generally not easy to form blocks or spheres, nor will it form insoluble spherical colloids after adding water.
