Selection of diatomite mud: it is very important to find out the type and cause of formation when selecting diatomite

Core tip: when we want to buy a certain product, we must have a little understanding of the product Let's take this opportunity to understand it together First, according to the genetic types of diatomite, it can be divided into volcanic sedimentary type and terrigenous sedimentary type The volcanic sedimentary type is also known as diatomite shale, and terrigenous sedimentary type is commonly known as diatomite The diatom shale in China is mainly distributed in Changbai, Jilin, Linqu, Shandong and Shengzhou, Zhejiang It was formed in the Cretaceous period (from 137 million years ago to 65 million years ago) The climate in Shanwang basin is warm and humid, and the vegetation in the lake basin and around the lake is flourishing Shanwang is famous in the world 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 Paint House News: when we want to buy a product, we must have a little understanding of the product Let's take this opportunity to understand it First, according to the types of diatomite, it can be divided into volcanic sedimentary type and terrigenous sedimentary type, which is also called diatomite shale Terrigenous sedimentary type is commonly called diatomite The diatom shale in China is mainly distributed in Changbai, Jilin, Linqu, Shandong and Shengzhou, Zhejiang It was formed in the Cretaceous period (from 137 million years ago to 65 million years ago) The climate in Shanwang basin is warm and humid, and the vegetation in the lake basin and around the lake is flourishing The world-famous Shanwang dinosaur lived in this era The growth and death of algae in the lake basin gradually accumulated and formed silicon Algal layer, while this generation is in the active period of crustal movement at the same time, the volcano erupts many times, the eruption of thousands of degrees of ultra-high temperature geological lava, which wraps up the diatom layer accumulated for hundreds of millions of years, and under the mutual compression of faults in the geological belt caused by the earthquake, huge earth pressure energy is produced Under the repeated "forging" of the massive energy of the thousands of high temperature molten lavas wrapped in the earth's crust and the tremendous pressure of the earth's crust, the "diatom nucleus" of diatoms, which is completely separated from the diatom body, will slowly evolve into diatom shale The density of diatom shale is 2.23-2.28g/cm3, the bulk density is 0.48-0.69/cm3, the specific surface area is 88-277m2 / g, the pore volume is 0.42-0.58cm3/g, the hardness is f = 6-7, the pore diameter is small, only 10nm, there are a lot of pores and micro gaps The terrigenous sedimentary type of diatom shale is mainly distributed in XUNDIAN, Yunnan and Miyi, Sichuan, and in the other 10 provinces It was formed in the Miocene (from 23 million years ago to 5.33 million years ago) The life cycle of single cell marine plankton is very short, its life cycle is only about 3-4 hours When its life is over, its body and shell separate from each other, and the body slowly sink to the bottom of the water Because it is the progenitor of a single cell, it does not need to mate, and its propagation speed is amazing This kind of algae, which keeps reproducing all the time, is deposited at the bottom of the water to form the original diatomite The density of diatomite is 0.3-0.5g/cm3, the specific surface area is 19-65m2 / g, the pore volume is 0.45-0.98cm3/g, the Mohs hardness is 1-1.5, and the pore radius is 50-80nm The diatoms that form diatomite can be divided into: 1 Dinoflagellate 2 Dinoflagellate 3 Dinoflagellate 4 Dinoflagellate 5 Boat type algae 6 Other diatomite types include crown diatomite and mast diatomite from all over the country: dinoflagellate and dinoflagellate from Linjiang, Jilin, Shandong, Shengzhou, Zhejiang, etc Different diatomite minerals from Tengchong, Yunnan, including diatomite microcyclic algae, straight chain algae and boat algae, Xuwen, Guangdong, Yunnan pioneer diatomite straight chain algae, round sieve algae and mast algae, have great differences in Diatomite Content and adsorption Therefore, the diatomite mud products made of diatomite from suitable producing areas have great differences in quality 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,
