Diatom mud classification: what is clay? What are the components?

Core tip: the laying material of diatom mud will use some natural ingredients such as clay The clay has plasticity after being moistened with water It can be deformed under a small pressure and remain unchanged for a long time Moreover, the specific surface area is large and the particles have negative electricity Therefore, it has good physical adsorption and surface chemical activity, and has the ability to exchange with other cations What is clay? What are the components? Basic introduction: clay is an important mineral raw material It is a very small (< 2 μ m) plastic aluminum silicate In addition to aluminum, clay also contains a small amount of magnesium, iron, sodium, potassium and calcium, generally composed of silicon Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating House News: the laying material of diatom mud will use some natural ingredients, such as clay The clay has plasticity after being wetted with water It can be deformed under a small pressure and can remain unchanged for a long time Moreover, the specific surface area is large and the particles have negative electricity, so it has good physical adsorption and surface chemical activity, and has the ability to exchange with other cations What is clay? What are the components? Basic introduction: clay is an important mineral raw material It is a very small (< 2 μ m) plastic aluminum silicate In addition to aluminum, clay also contains a small amount of magnesium, iron, sodium, potassium and calcium, generally formed by the weathering of silicate minerals on the earth's surface Clay is an important mineral raw material, which is widely distributed in rocks and soils around the world It can be used to make ceramic products, refractories, building materials, etc Industrial clay ores include kaolin, bentonite (mainly composed of montmorillonite), active clay (indefinite composition), etc Kaolin was first mined in Gaoling village of Jiangxi Province by China to make ceramics Bentonite was first mined in Wyoming in 1888 and activated clay in Texas in 1906 Composition introduction: clay is an important mineral raw material It is composed of a variety of hydrated silicates and a certain amount of alumina, alkali metal oxides and alkali earth metal oxides, and contains quartz, feldspar, mica, sulfate, sulfide, carbonate and other impurities The particles of clay minerals are small, usually in the range of colloidal size, and they are crystal or non crystal, most of them are lamellar, a few are tubular and rod-shaped Clay minerals are plastic after being wetted with water, can be deformed under small pressure and can remain unchanged for a long time, and have large specific surface area and negative electricity on particles, so they have good physical adsorption and surface chemical activity, and have the ability to exchange with other cations Distribution: clay minerals are widely distributed in rocks and soils around the world Bentonite resources in the world are more than 1.3gt, mainly distributed in the United States and Canada The reserves of kaolinite are about 1.6gt, mainly distributed in China, the United States, the Soviet Union, Mexico, Spain and other countries China is a country rich in kaolin resources, with excellent mineral quality and complete genetic types Its main producing areas include Suzhou, Hubei Junxian and Xuyong County, Sichuan Province Active clay is mainly produced in the United States and Canada The above is the introduction of clay, hoping to help you Home of coatings focuses on the news and information of coatings, diatom mud, paint coatings, coating process, fire retardant coatings and coatings, paint coatings, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
