Does diatom mud dry powder contain asbestos fibers?

The main component of diatomaceous mud is diatomaceous earth, which is a biogenic siliceous sedimentary rock composed mainly of the remains of ancient diatoms. Diatoms are the first single-celled algae to appear on Earth, living in seawater or lake water, and are extremely small in size, often growing and multiplying at an alarming rate. Over hundreds of millions of years, diatoms and other plankton have been deposited into diatom mud at the bottom of the water.

Using an electron microscope to observe diatom mud, diatom minerals are porous materials with micron-sized pores, and their particle surfaces have countless tiny pores, regularly and neatly arranged in circles and needles, and the number of microscopic pores per unit area is thousands of times greater than that of charcoal. This molecular sieve structure makes it have extremely strong physical adsorption performance and ion exchange performance. After refining, it is widely used in many fields such as alcohol and medical injection filtration, water purifiers, food additives, nuclear radioadsorbents, etc.; It can also slowly and continuously release negative oxygen ions, which can decompose harmful carcinogens such as formaldehyde, benzene, and radon.

Diatom mud is a new type of natural environmentally friendly paint, used to replace latex paint and wallpaper, suitable for villas, hotels, homes, apartments, hospitals and other interior wall decoration. Due to the strong hygroscopicity and poor water resistance of diatomaceous earth, it is not widely used in exterior walls. Diatomaceous earth is derived from the diatom minerals formed by marine seaweed plants over hundreds of millions of years, and its main components are opal and its variants, followed by clay minerals - mica, kaolinite and mineral detritals, including quartz, biotite and organic impurities.

The chemical composition of diatomaceous earth is mainly SiO2, and the diatomaceous earth with high purity is white, and it is light gray or light yellow because it contains a small amount of Al2O3, Fe2O3, CaO, MGO and organic impurities. Diatomaceous earth is loose soil, with a density of 75 95 blue light, a specific surface area of 40 65m2 g, a porosity of 80% 95%, an oil absorption of 120 180g of cooked linseed oil 100g, and the water absorption rate is several times of its own volume.

Structural features. Under the electron microscope, the special porous structure of diatomaceous earth can be observed, which is regularly and neatly arranged in a circular or needle-shaped, and the number of micropores per unit area is thousands of times that of activated carbon. The prominent molecular lattice structure of diatomaceous earth determines its unique function, which makes it have extremely strong physical adsorption and ion exchange properties.

Resource distribution. Diatomaceous earth is mainly distributed in the United States, China, Denmark, France, Russia and Japan. The United States has diatomaceous earth reserves of 100 million tons and basic reserves of 500 million tons [7] [8], accounting for the first place in the world.

China ranks second only to the United States in the world. There are 10 provinces (regions) with diatomite reserves in China, with the largest reserves of high-quality diatomite in Changbai Linjiang, Jilin Province, accounting for more than half of the country, followed by Yunnan, Fujian, Zhejiang and other places, and diatomite deposits have also been found in Heilongjiang, Hebei, Shanxi, Hainan and other provinces and cities.

Add natural clay to ensure the environmental protection of diatom mud and achieve glue-free walling;

Add wood fiber (non-cheap glass fiber, long, inhaled will be harmful to the body) to increase the solidity after the wall, anti-cracking, environmental protection;

Activated titanium is added, and photocatalyst technology is used to realize the function of diatom mud to decompose formaldehyde;

Environmentally friendly inorganic iron oxide is added to ensure that the color of diatom mud is soft and will never fade;

Add inorganic aggregate (fine sand, medium sand, coarse sand, that is, quartz sand) to assist modeling, increase three-dimensional sense and vitality and artistry.

Definition of diatom mud: a dry powdery interior wall decoration coating material prepared with inorganic cementitious material as the main binder material and diatom material as the main functional filler. The main component of diatom mud is diatomaceous earth, diatomaceous earth is dry powder, and the form of diatom mud without adding other chemicals is determined by the main ingredient diatomaceous earth.

So from the industry standard definition and main ingredients, it can be inferred that the real diatom mud is dry powder.

Advantages of dry powdered diatom mud:

The shelf life of dry powder diatom mud is long, and water can be added during the construction process, which is much more convenient than liquid paint during transportation and storage.

Natural without chemical additives, the composition of traditional coatings has both water and a lot of organic matter, which is easy to be contaminated by bacteria during the encapsulation process, so that many coatings have mildew and odor after opening. The dry powder diatom mud is different, its main component is diatomaceous earth, and other added materials are inorganic materials, and as we all know, inorganic materials will not be used as carriers by bacteria, so there is no mildew and deterioration of diatom mud, so there is no need to worry about whether there are preservatives added in it.

Dry powder diatom mud is green and environmentally friendly, no harmful gas volatilization, far better than latex paint, paint and other organic chemical products, its composition contains many harmful components to the human body, it is easy to volatilize indoors after decoration, forming indoor pollution.

Diatom mud paint is a dry powder diatom mud, a pure natural material without adding any gel and organic substances, and is packaged in dry powder rather than liquid filling, so consumers can use it with confidence.
