Properties of Hydroxyethyl Cellulose and Solution Preparation Method
Hydroxyethyl Cellulose
1. Chemical name: hydroxyethyl cellulose (HEC)
This product is white or yellowish odorless, tasteless and easy-flowing powder, 40 mesh sieve rate ≥ 99%; softening temperature: 135-140°C; apparent density: 0.35-0.61g/ml; decomposition temperature: 205-210°C; Slow burning speed; equilibrium temperature: 23°C; 6% at 50%rh, 29% at 84%rh.
It is soluble in cold water and hot water, and generally insoluble in most organic solvents. The viscosity changes slightly in the range of PH value 2-12, but the viscosity decreases beyond this range.
2. important properties:
As a non-ionic surfactant, hydroxyethyl cellulose has the following properties in addition to thickening, suspending, binding, floating, film-forming, dispersing, water-retaining and providing protective colloid:
(1) HEC is soluble in hot water or cold water, and does not precipitate at high temperature or boiling, so that it has a wide range of solubility and viscosity characteristics, and non-thermal gelation;
(2)It is non-ionic and can coexist with a wide range of other water-soluble polymers, surfactants, and salts. It is an excellent colloidal thickener for 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.
3. Solution and preparation method
(1)Add a specified amount of clean water to the container;
(2)Add hydroxyethyl cellulose under low-speed stirring, stir until all the hydroxyethyl cellulose, and stir until all materials are completely wet;
