Basic chemical raw material manufacturing


This is the "foundation school" of the chemical industry, mainly producing various inorganic acids, inorganic bases, inorganic salts, organic chemical raw materials, etc. The commonly mentioned "three acids and two bases" (sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide, soda ash) are all the "masterpieces" of this school. Sulfuric acid is widely used in industry, such as in the manufacture of fertilizers, pesticides, and explosives, and also plays an important role in petroleum refining and metal smelting; sodium hydroxide is often used in papermaking, textiles, and dyeing industries, and is an important raw material for the production of soap and detergents.

Nobia - Substitute Oil for Plastics | The Development Direction of the Printing Industry Under the "Plastic Restriction Order"

Substitute oil is an environmentally friendly coating developed to replace plastic films in traditional processes. When applied to paper, it achieves a lamination effect, offering good ink adhesion, wear resistance, folding resistance, burst resistance, scratch resistance, matte finish, and ink protection, while also being biodegradable and recyclable. This helps achieve the goals of plastic reduction, plastic limitation, and environmentally friendly recycling. In the printing industry, using substitute oil instead of BOPP film reduces white pollution, carbon emissions, and promotes sustainable development in the packaging industry.
