Titanium dioxide is a kind of white inorganic pigment with non-toxic, best opacity, best whiteness and brightness. It is regarded as one of the best white pigments in the world. Titanium white adhesion, not easy to chemical changes, is always white. Widely used in coatings, plastics, paper, printing ink, chemical fiber, rubber, cosmetics and other industries. It has a very high melting point and is also used in the manufacture of fire-resistant glass, glazes, enamels, clay, high-temperature resistant experimental vessels and so on.
Zhongjing follows the strict production process of Titanium Oxide TiO2 powder. Integrating innovative research in inorganic coating, organic treatment, salt treatment, calcination control, hydrolysis and product application, Zhongjing develops multi-inorganic coating and new organic treatment technology. The new generation of rutile titanium dioxide power developed by Zhongjing is suitable for various architectural coatings, industrial paints, anticorrosive paints, inks, powder coatings and other industries.
Zhongjing offers Titanium Oxide TiO2 power produced by sulfuric acid method. The titanium dioxide production sulphate process is to carry out acid hydrolysis reaction between Titanium Oxide TiO2 powder and concentrated sulfuric acid to produce titanium sulfite, which is hydrolyzed to generate titanium dioxide product. This method can produce both anatase and rutile titanium dioxide. With cheap and accessible ilmenite and sulfuric acid as raw materials, quality Titanium Oxide TiO2 can be produced.
The characteristics of titanium dioxide
The surface of titanium dioxide pigment particles exhibits crystalline TiO2 properties, which are divided into rutile titanium dioxide power and anatase grade titanium dioxide power. Therefore, it has the characteristics of hiding power, whiteness, oil absorption, etc. The low density of the compound makes the product better dispersibility and applicability when used in the coating system.
The quality requirements of titanium dioxide white pigments in printing ink
Different types of ink products have different quality requirements for titanium dioxide white pigments. Divided into rutile type and anatase type, practice has proved that anatase type titanium dioxide can be widely used in various types of ink formulations. Many customers have reported that anatase grade titanium dioxide pigments have many advantages compared with other titanium dioxide pigments.
How to distinguish the authenticity of titanium dioxide with physical methods
The easiest way is to compare the hand feel. Fake titanium dioxide is smoother, while the real titanium dioxide is astringent; the fake one is easy to wash off, but the real one is not easy to wash off. Take a cup of water and throw away the titanium dioxide. Go in, the ones that float up are true, the ones that settle down are false (if it is an activated modified product, it won’t work)
How to use distinguish the authenticity of titanium dioxide with chemical methods
Mixed with light or heavy calcium: adding dilute sulfuric acid or hydrochloric acid, bubbles can make the clarified lime water turbid, because calcium carbonate will react with acid to produce carbon dioxide; mixed with Lithopone: adding dilute sulfuric acid or hydrochloric acid, there is a smell of rotten eggs ; Make latex paint, add iron red, deep color, indicating that the poor hiding power is fake or poor quality titanium dioxide.
