Chemical materials have important applications for all walks of life, but do you know what kinds of chemical materials are? Here is a detailed introduction to the types of chemical materials.

Types of chemical materials

Types of chemical materials:

Due to the different materials and process conditions of chemical production, there are many types of chemical materials with complex models and specifications, including general engineering materials and chemical equipment materials with special characteristics and special uses.

Chemical materials are divided into two categories: metallic materials and non-metallic materials. Chemical metal materials can be divided into black metal materials and non-ferrous metal materials. Ferrous materials mainly refer to steel, and most chemical machinery and equipment are made of cast iron and carbon steel. Iron, high-alloy steels (such as high-ferrosilicon, high-nickel iron and various stainless steels), as well as nickel, copper, aluminum, titanium, zirconium and their alloys are also widely used in chemical production. , ceramic, enamel, impermeable graphite, etc. Impermeable graphite is heat resistant, acid resistant, and has a high thermal conductivity, and is used in large quantities. They are resistant to acid, but they are fragile and cannot assemble large-volume equipment, so their own use is limited, but they can be used for enamel and to do wire on metal surfaces, to make corrosion-resistant enamel equipment, water tanks with glass lining (or lining), water tanks, etc.

Between metal and non-metal, there are also supercooled liquid structures and strong corrosion resistant amorphous alloys. Some are close to alkyl and precious metals, and it is a developing material.

In order to take advantage of different materials, a variety of composite materials have been developed, including: ① metal and metal composite materials, such as sandwich metal plates, the use of high-strength, low-corrosion materials (such as carbon steel)(aluminum alloy) as, corrosion resistance. ③ Nonmetallic and metallic composite materials, such as alloy ceramics, have a certain strength and can withstand high temperatures. The above is the introduction of the types of chemical materials.
