HEC is a white or yellowish mobile powder. 40 screen pass rate:≥99%. Intenerating point:135140. Vision density:0.350.61lg/ml. Dispersing point:205210.Average moisture:6% at 23 84%rh. It can dissolve in other cool or hot water. .Normal it does not dissolve in organic solvents. Viscosity change is small when PH is within 2-12 but decrease when PH low than the range.
HEC Important characteristics
As a non ionic surface-active agent, it possesses the following characteristics in addition to acts of thicker agent, suspending agent, adhesive agent, emulsification agent, coating agent, water keeping agent and protective agent.
1. HEC can dissolve in both cool and hot water while it does not deposit when in hot or boiling water showing large range of non-gelatin capacity.
2. Because of non-ionic base, it can be coexist with other water-soluble polymizers, surface-active agent and salts.
3. Water keeping ability is twice that of Methyl Cellulose (MC)showing good flowage adjusting ability.
4.It is stable in viscosity and anti-mildew and makes coatings good open can effect ion as well as excellent floating-plain effects.
Application:
1. For water-based latex coatings: It can significantly improve thickening and leveling performance.
2. For Oil drilling: It can improve mud carrying capacity during drilling, and prevent a large amount of water from entering the oil layer from the mud, and stabilize the oil layer production capacity.
3. For building construction and building materials: HEC is an effective thickener and binder for cement slurry and mortar. It can improve the fluidity and construction performance of the mortar, and prolong the water evaporation time, and increase the initial cracks of the concrete. It used for painting gypsum, bonding gypsum, gypsum putty can significantly improve its water retention and bonding strength.
4. For toothpaste: HEC can guarantee the stability of toothpaste paste due to its strong salt resistance and acid resistance. In addition, the toothpaste is not easy to dry due to its high water retention and emulsifying ability.
5. For water-based ink, HEC can make the ink dry quickly and not penetrate.
6.HEC is widely used in textile printing and dyeing, papermaking, and daily chemicals.
Steps and methods of making solution:
1. Add a prescribed amount of clean water to the container.
2. If hydroxyethyl cellulose is stirred at low speed, stir until all materials are completely wet.
3. Add other ingredients of the formula and stir well.
4. The surface-treated HEC will form a viscosity in about 30 minutes after dispersing it in water. Or after the material is completely wet, add alkali to adjust the pH between 8 and 10 to form a viscosity.
