As a non-ionic surfactant, hydroxyethyl cellulose (HEC) has the following properties in addition to thickening, suspending, binding, flotation, film-forming, dispersing, retaining water and providing protective colloids:
1. HEC is soluble in hot or cold water, and does not precipitate at high temperature or boiling, so it has a wide range of solubility and viscosity characteristics, and non-thermal gelation;
2. The non-ionic itself can coexist with other water-soluble polymers, surfactants and salts in a wide range, and is an excellent colloidal thickener containing high-concentration electrolyte solutions;
3. The water retention capacity is twice as high as that of methyl cellulose, and it has better flow regulation.
4. Compared with the recognized methyl cellulose and hydroxypropyl methyl cellulose, the dispersing ability of HEC is the worst, but the protective colloid ability is the strongest.
How to use hydroxyethyl cellulose？
1. Join directly in production
1. Add clean water to a large bucket equipped with a high-shear blender.
2. Start stirring continuously at low speed and slowly sieve the hydroxyethyl cellulose into the solution evenly.
3. Continue stirring until all particles are soaked through.
4. Then add lightning protection agent, alkaline additives such as pigments, dispersing aids, ammonia water.
5. Stir until all the hydroxyethyl cellulose is completely dissolved (the viscosity of the solution increases significantly) before adding other components in the formula, and grind until it becomes
