Background and overview

Globally, Iron Oxide is the second largest inorganic pigment after Titanium Dioxide and the first largest color inorganic pigment. Iron oxide pigments mainly include iron oxide red, yellow, black and brown with iron oxide as the basic material. Iron oxide yellow, also known as hydroxyl iron oxide (FeOOH), will be dehydrated and decomposed into red at about 177 ℃, so the application of ordinary iron yellow pigment in high-temperature occasions such as plastic processing and baking coatings is limited. Iron oxide yellow pigment can improve its temperature resistance through surface coating, so as to expand the application field of iron oxide yellow pigment.

The chemical formula of iron oxide yellow (also known as hydroxyl iron) is α- Fe2O3 · H2O or α- FeOOH, with needle like structure and yellow powder, is a kind of particle size less than 0.1 μ m. Iron series pigment with good dispersibility in transparent medium has strong coloring power, high covering power, insoluble in alkali and slightly soluble in ACID. Synthetic iron oxide yellow has the characteristics of light resistance, good dispersion, non-toxic, tasteless and difficult to be absorbed by human body. It is widely used in coatings, plastics, ink and pharmaceutical industry.

Physical and chemical properties and structure

1. Iron oxide yellow pigment has acid and alkali resistance, resistance to general weak and dilute acids, and is very stable in alkaline solution of any concentration.

2. Iron oxide yellow pigment has certain light resistance, heat resistance and weather resistance. Its coating color is durable and can keep the coating from being damaged in light. Iron oxide yellow pigment is stable in a certain temperature range, but beyond the limit temperature, its color begins to change, and the degree of change is more significant with the increase of temperature. Iron oxide yellow pigment is not affected by cold, heat, dry and wet weather conditions.

3. Iron oxide yellow pigment is very stable in any ambient atmosphere (such as gases containing H 2S, Co, so 2, HCl, no, etc.). And resistant to pollution, water, oil and solvent penetration, insoluble in water, mineral oil or vegetable oil.

4. Iron oxide yellow pigment has strong coloring power and high hiding power. With the decrease of pigment particle size, its coloring power is stronger.

application

Nano iron oxide yellow has the characteristics of acid resistance, alkali resistance, non toxicity and low price. It is widely used in coatings, plastics and rubber. The particle size of nano iron yellow is less than 100 nm, which makes it have some unique characteristics. When light shines on its surface, transmission and diffraction will occur, showing transparent yellow, and can strongly absorb ultraviolet rays, Therefore, it can be used as a functional pigment for the surface paint of high-grade cars, precision instruments, bicycles, motorcycles, cosmetics, food, drugs and other coloring additives.

2. On the other hand, the sulfate process involves treating ilmenite ore with sulfuric acid to produce titanyl sulfate solution, which is then calcined to produce titanium dioxide. This method produces lower-quality titanium dioxide with a higher impurity level, making it less expensive than the chloride process. However, the sulfate process is more commonly used due to its lower cost and higher yield.
3. Guangdong Huiyun Titanium Industry Co., Ltd is a Chinese manufacturer of rutile and other titanium products. The company's rutile production is primarily used for the manufacture of titanium dioxide, which is used in the production of pigments, ceramics, and coatings. Guangdong Huiyun Titanium Industry Co., Ltd is also a leading supplier of titanium sponge, which is used in the production of titanium metal and alloys.
4. China's dominance in the titanium dioxide market is a testament to its robust industrial infrastructure and advanced chemical processing capabilities. According to industry reports, China accounts for more than half of the global titanium dioxide production, making it the largest producer and exporter of this pigment worldwide. This is largely due to the country's abundant reserves of titanium-bearing minerals, such as ilmenite and rutile, which are the primary raw materials for TiO2 production.
5. Furthermore, China's strong manufacturing base and export-oriented economy have enabled the country to become a major supplier of TiO2 to markets around the world. Chinese TiO2 manufacturers have been able to leverage economies of scale and technological advancements to drive down production costs, making their products attractive to buyers both domestically and internationally.
6. Shampoo manufacturers have long been exploring the benefits of incorporating various ingredients into their products to enhance their effectiveness and user experience. Two such ingredients that have gained significant attention are mica and titanium dioxide. In this article, we will delve into the role of these minerals in shampoo and how they contribute to its overall performance.
