Titanium dioxide is one of the most widely used inorganic functional white pigments and functional raw materials in modern industry. It owns outstanding whiteness, high hiding power and strong ultraviolet shielding ability, so it is largely added into architectural coatings, industrial paints, printing inks and plastic products to improve coloring effect, anti-aging performance and surface gloss. In daily chemical industry, it is a core additive for sunscreen cream, foundation, toothpaste and cosmetics, which can effectively block ultraviolet rays and achieve whitening and skin protection effects. In food industry, food-grade titanium dioxide can be used as food whitening and brightening agent for candy, pastry and beverage. Besides, it is an essential raw material for ceramic glaze, papermaking filling agent and chemical fiber delustering agent. In new energy and electronic fields, nano titanium dioxide is applied in lithium battery separators, photocatalytic degradation materials and photoelectric sensors. It can enhance product durability, reduce aging speed and optimize physical and chemical properties of finished products. It covers paint, daily chemical, food, new energy, building materials and many other fields, with stable supply demand and mature application technology.

Titanium dioxide belongs to low-risk inorganic powder material with low overall toxicity and high safety coefficient under normal industrial use. Short-term skin contact will not cause obvious irritation, only long-term attachment may cause slight dry skin; direct eye contact with scattered powder will produce foreign body sensation and mild conjunctival irritation. Long-term inhalation of a large amount of titanium dioxide dust will easily cause respiratory tract discomfort such as dry throat and cough, and long-term excessive inhalation may affect lung health. Accidental oral intake in small dose basically causes no obvious poisoning reaction, but large intake will lead to gastrointestinal distension and poor digestion. During operation, workers need to wear dust-proof masks, protective gloves and dust-proof work clothes, and keep working area well ventilated to reduce dust floating. Store products in cool dry sealed warehouse, keep away from strong oxidants and corrosive substances, and strictly separate from food raw materials. In case of skin contact, clean with flowing water timely; if dust enters eyes, rinse continuously with clean water for more than 15 minutes. Production waste and residual powder shall be recycled and disposed in accordance with industrial waste standards, and shall not be discharged randomly to avoid causing dust pollution and affecting surrounding air environment, so as to ensure personal operation safety and public environmental safety.
