Inorganic Chemistry

Inorganic acid, also known as mineral acid, is a general term for acids in inorganic compounds. Inorganic acids are generally inorganic compounds that can dissociate hydrogen ions. A compound consisting of hydrogen and a non-metallic element or group. According to the composition, inorganic acids can be divided into oxyacids, anaerobic acids, complex acids, mixed acids, superacids, etc. According to the degree of dissociation, they can be divided into strong acids and weak acids, and according to the ionizable hydrogen ion The number is divided into monobasic acid, dibasic acid and polybasic acid.

Industrial gas is a bottled compressed liquid gas, which is in a gaseous state at normal temperature and pressure. There are many types of gas, and it is mainly used in various industrial manufacturing. There are many types of gas products, which can be roughly divided into two categories: general industrial gas and special gas. General industrial gas production and sales are large, but the purity requirements are not high. Although the production and sales of special gases are small, they have extremely strict requirements on the purity or composition of different special gases, the maximum allowable content of harmful impurities, and the packaging, storage and transportation of products. .

Coating is a solid continuous film obtained by one-time application of paint. It is a thin layer of plastic applied to metal, fabric, plastic and other substrates for protection, insulation, decoration and other purposes. The paint can be gaseous, liquid, or solid, and the type and state of the paint are usually determined according to the substrate to be sprayed.

Silica gel alias: Silicic acid gel, is a highly active adsorption material, which is an amorphous substance. The main component of silica gel is silica, which is chemically stable and does not burn. Generally speaking, silica gel can be divided into two categories: organic silica gel and inorganic silica gel according to its properties and components.
