Titanium white production
Titanium white is a white pigment widely used in various industries. It has two main production processes, which are sulfate method production and chloride method production. The sulfate method produces a more stable pigment and the chloride method produces more concentrated iron oxide. Titanium white production is a complex process that requires a high degree of precision and quality control.
The first step in titanium white production is to mine the raw materials, which are iron ore, titanium dioxide, and soda. The iron ore is then converted into iron oxide, commonly known as rust. The iron oxide is heated at a high temperature to produce iron oxide with a high degree of purity. This is followed by the combination of iron oxide with titanium dioxide to form a mixture that has the correct ratio for titanium white production.
The titanium white mixture undergoes the sulfate or chloride process, depending on the desired result. In the sulfate method, sodium sulfate and ethylene glycol are added to the mixture and heated until all the ingredients are uniform and distributed. The mixture is then cooled, filtered, and dried to produce a dry powder that is ready for use. In the chloride method, sodium chloride and a small amount of acetic acid are mixed and heated until the mixture has a homogenous consistency. Cooling and filtering completes the second process of titanium white production.
The final step of titanium white production is the evaporation process. The dry powder is spray dried to a specific particle size, after which small particles of titanium white are collected in a desired size. The titanium white particles are then sieved and collected according to their desired particle size. After this, the titanium white powder goes through a quality control process to ensure that the color and hue meet industry standards. Once the quality control process is complete, the titanium white particles can be packaged for use in various industries.
Titanium white production requires specialized knowledge and quality control techniques to ensure the best quality of titanium white is achieved. It is an energy-intensive and costly process, but the result is an incredibly useful product that is highly sought after across a variety of industries.
