tio2 procurement

To address this environmental challenge, Chinese companies have been investing in research and development to improve the efficiency of TiO2 production methods and reduce their carbon footprint. For instance, the adoption of advanced technologies like the sulfate process, which has lower emissions compared to the chloride process, is being encouraged. Additionally, there is a growing focus on utilizing renewable energy sources to power these manufacturing plants.

  • HEC is designed to offer enhanced solubility and viscosity control in aqueous solutions. When it comes to alcohols, HEC displays limited solubility in ethanol. The solubility of HEC in this organic solvent can be influenced by its hydroxyethyl substitution degree; generally, as the degree of substitution increases, the solubility in ethanol may slightly improve, but it remains significantly lower than in water. This limited solubility is primarily attributed to the hydrophilic nature of the hydroxyethyl groups, which favor interaction with polar solvents like water over non-polar or slightly polar solvents like ethanol.
