What is diatomaceous earth and what is the harm of diatomaceous earth to people?

Diatomaceous earth is composed of amorphous SiO2 and contains small amounts of Fe2O3, CaO, Mgo, Al2O3 and organic impurities.

Diatomaceous earth is usually light yellow or light gray, soft, porous and light, and is commonly used as thermal insulation materials, filter materials, fillers, abrasive materials, sodium silicate raw materials, decolorizing agents and catalyst carriers.

The special porous structure of natural diatomaceous earth can be observed under the microscope, and this microporous structure is the reason for the characteristic physical and chemical properties of diatomaceous earth.

The main component of diatomaceous earth as a carrier is SiO2. For example, the active component of the industrial vanadium catalyst is V2O5, the co-catalyst is alkali metal sulfate, and the carrier is refined diatomaceous earth. Experiments showed that SiO2 had a stabilizing effect on the active components and strengthened with the increase of K2O or Na2O content.

The activity of the catalyst is also related to the dispersion of the support and the pore structure. After diatomaceous earth is treated with acid, the content of oxide impurities decreases, the content of SiO2 increases, and the specific surface area and pore volume also increase, so the carrier effect of refined diatomaceous earth is better than that of natural diatomaceous earth.

Diatomaceous earth is generally formed from the remains of silicate after the death of single-celled algae collectively known as diatoms, and is essentially amorphous SiO2 containing water

Diatoms can survive in both freshwater and saltwater, there are many species, and they can generally be divided into "centrium" diatoms and "pinnae" diatoms, and in each order, there are many "genera", which are quite complex.

The main ingredient of natural diatomaceous earth is SiO2, and the color of high-quality ones is white, and the SiO2 content often exceeds 70%. The monomer diatom is colorless and transparent, and the color of diatomaceous earth depends on clay minerals and organic matter, etc., and the composition of diatoms on different mineral sources is different.

Diatomaceous earth is a fossilized diatomaceous accumulation deposit formed by a single-celled plant called diatom after its death and accumulation period of about 1 to 20,000 years. Diatoms are one of the first protists to appear on Earth, living in seawater or lake water. It is this diatom that provides oxygen to the earth through photosynthesis and facilitates the birth of humans, animals and plants.

This diatomaceous earth is formed by the deposition of the remains of the single-celled aquatic plant diatoms, the unique property of this diatom is that it can absorb the free silicon in the water to form its bones, and when its life is over, it is deposited to form diatomite deposits under certain geological conditions. It has some unique properties, such as: porosity, lower concentration, larger specific surface area, relative incompressibility and chemical stability, through the crushing, sorting, calcination, air flow classification, impurity removal and other processing processes of the original soil to change its particle size distribution state and surface properties, can be applied to paint additives and other industrial requirements.

Diatomaceous earth is a siliceous rock, mainly distributed in China, the United States, Japan, Denmark, France, Romania and other countries. It is a siliceous sedimentary rock of biogenetic origin, which is mainly composed of the remains of ancient diatoms. Its chemical composition is mainly SiO2, which can be expressed by SiO2·NH2O, and the mineral composition is opal and its variants.

The special porous structure of natural diatomaceous earth can be observed under the microscope, such as: porosity, low concentration, large specific surface area, relative incompressibility and chemical stability, which is the reason for the characteristic physical and chemical properties of diatomaceous earth.

Regular diatomaceous earth in general.

is not harmful, unqualified diatom mud.

Excessive radiation is harmful only if it exceeds the standard, as follows:

Hazards of excessive radiation of diatom mud:

When radioactive substances enter the human body, some will cause damage to the body in a short period of time, while others will have a long incubation period and manifest themselves over many years. Radioactive substances are mainly harmful to the human body in the following ways:

1. Cause direct damage.

Radioactive substances can directly ionize atoms or molecules of body matter, destroying some macromolecules in the body, such as ribonucleic acid and deoxyribonucleic acid.

Protein molecules and some important enzymes.

2. Cause indirect damage.

Excessive radiation will first cause water molecules that are widely present in the body.

Ionization separates to generate more active hydrogen ions, hydroxide ions, and molecular products, which interact with the body's organic components, causing consequences corresponding to direct damage.

3. Produce long-term effects.

There is a long incubation period and mainly leukemia occurs.

Damage such as cataracts, radiation carcinogenesis, shortened lifespan, and physical diseases such as genetic effects. And according to research by medical authorities, the proportion of children born to pregnant women who have been exposed to radiation will be greatly increased with cancer and leukemia as a child. Some of them receive a small effective dose and may not have significant physiological damage.

Hello, dear, Shanxi Xinghua Village Fen Distillery Co., Ltd. ****.

<>1. Adsorption. It can effectively adsorb positive charges. When particles smaller than the internal pores of diatomaceous earth collide on the internal surface of porous diatomaceous earth, they are attracted to electric charges and thus play an adsorption role.

2. Sieving. When the fluid flows through diatomaceous earth, the pores of diatomaceous earth are smaller than the particle size of impurity particles, and the impurity judgment particles cannot pass through and are intercepted. 3. Filtration.

Some of the relatively small impurity particles on the surface of the filter cake are blocked by the tortuous microporous structure inside the diatomaceous earth and the finer pores inside the filter cake, which play a role in filtration. Buried in the Wang.

For diatomaceous earth, many friends still have a lot of things they don't understand, in fact, there are still many uses of diatomaceous earth, and it also has a very big role in our daily life, but we haven't found it, so what is the real role of diatomaceous earth? Let me tell you more about it now.

Diatomaceous earth can effectively adsorb formaldehyde, and at the same time, it also has strong adsorption power for harmful gases such as benzene and ammonia. Diatomaceous earth can also automatically adjust the humidity of indoor air, when the temperature changes in the morning and evening or when the seasons change, diatomaceous earth can automatically absorb and release moisture according to the humidity in the air, so as to achieve the purpose of adjusting the humidity of the surrounding air in the environment.

Tips: Diatomaceous earth coating additives have the characteristics of large porosity, strong absorption, stable chemical properties, wear resistance, heat resistance, etc., which can provide excellent surface properties, increase capacity, thicken and improve adhesion for coatings. Due to its large pore volume, the drying time of the coating film can be shortened.

It also reduces the amount of resin used and reduces costs. This product is considered to be a high-efficiency matting powder product for coatings with good cost performance, and has been widely used in waterborne diatom mud as a designated product by many large paint manufacturers in the world.

The above is the specific role of diatomaceous earth, do you find that there are many places that can be used in your life, you can go to learn more about it.
