1. It can be melted when heated above 200°C, and the ash content is about 0.5% when burned, and it is neutral after being made into a slurry with water. As for its viscosity, it depends on its degree of polymerization.
2. Solubility in water is inversely proportional to temperature, high temperature has low solubility, low temperature has high solubility.
3. Soluble in the mixture of water and organic solvents such as methanol, ethanol, ethylene glycol, glycerin and acetone.
4. When the metal salt or organic electrolyte exists in its aqueous solution, the solution can still remain stable. When the electrolyte is added in a large amount, gel or precipitation will appear.
5. Surface activity. Its molecules contain hydrophilic groups and hydrophobic groups, which have emulsification, colloid protection and phase stability.
6. Thermal gelation. When the aqueous solution rises to a certain temperature (above the gel temperature), it will become cloudy until it gels or precipitates, making the solution lose its viscosity, but it can return to its original state by cooling. The temperature at which gelation and precipitation occur depends on the type of product, the concentration of the solution and the rate of heating.
7. The pH value is stable. The viscosity in water is not easily affected by acid and alkali. After adding a certain amount of alkali, no matter high temperature or low temperature, it will not cause decomposition or chain splitting.
8. The solution can form a transparent, tough and elastic film on the surface after drying. It can resist organic solvents, fats and various oils. It will not turn yellow when exposed to light, and will not appear hairy cracks. It can be dissolved in water again. If formaldehyde is added to the solution or post-treated with formaldehyde, the film is insoluble in water but still partially swells.
9. Thickening. It can thicken water and non-aqueous systems, and has good anti-sag performance.
10. Increased viscosity. Its aqueous solution has strong cohesive force, which can improve the cohesive force of cement, gypsum, paint, pigment, wallpaper and other materials.
11. Suspended matter. It can be used to control the coagulation and precipitation of solid particles.
12. Protective colloid to increase its stability. It can prevent the aggregation and coagulation of droplets and pigments, and effectively prevent precipitation.
