At present, many people in home decoration will choose diatom mud, but what is diatom mud, what is the effect? ​​How to identify true and false? These problems have confused many friends, the article will introduce diatom mud and diatoms in detail. How to identify true and false mud: What is diatom mud: Diatom mud is a pure natural indoor functional wall material with strong physical adsorption and ion exchange. It has the functions of eliminating formaldehyde, regulating humidity, sterilization, fire retardant, heat insulation, noise reduction and deodorization. The wall is self-cleaning and releases negative oxygen ions. It is used to replace wallpaper and latex paint. It is suitable for interior wall decoration of villas, apartments, hotels, homes, hospitals, etc. As a high-tech new decorative material, diatom mud emphasizes functionality, but its function is abstract, which is difficult for outsiders to identify with the naked eye. The main component of diatom mud is diatomaceous earth, and its appearance is powdery. Diatomaceous earth has 5000~6000 times more pores than activated carbon, so it has a strong adsorption capacity. More than less diatomaceous earth content, good quality and badness have a great impact on the function of diatom mud. In addition, diatomaceous earth itself is as non-tacky as sand, and diatom mud must be filled with a viscous substance. Whether it is a chemical resin or a natural material, whether it will block the pores of diatomaceous earth, these also directly affect The functionality of diatom mud. Diatom mud has the effect of thermal insulation, but it is not a thermal insulation material, because the construction thickness requirement of diatom mud is 2-2.5mm, and some individual textures can reach 2.5-3mm. The construction thickness of the wall is thick and natural. It will have the effect of thermal insulation. The diatom mud itself has no pollution and has many functions, which are unmatched by traditional paints such as latex paint and wallpaper. When decorating with diatom mud, there is no need to move, because there is no taste in the process of constructing diatom mud. Diatom mud identification method: At present, there are many plazas in the market that carry out false propaganda. In fact, they sell all kinds of putty powder or chemical agents such as photocatalyst. These diatom muds are all added with chemical adhesives, not only do not have Functional, but also release harmful substances such as formaldehyde and benzene, causing new pollution. In order to enable consumers to buy genuine products, Tubar Rabbit Shenzhen Decoration Network introduces some simple and easy identification methods: 1, look at the proportion There is a saying on the Internet (the lighter the better. If a large amount of stone is mixed, the specific gravity is very large, it feels very heavy, indicating that the content of diatomite is low). In fact, diatom mud is not as light as possible, because the content of diatomaceous earth is strictly required, and diatomaceous earth is formed by pulverized diatom minerals into powder, which mainly depends on the construction of powdered diatomaceous earth. Whether it has the function of adsorption decomposition after reaching the wall. 2, see the proportion of water Add water when blending, the ratio is close to 1:1. In practice, if the water is less than 0.5, the content of diatomite may be less than 20%. But mainly depends on what conditions the substrate is made and the material of the substrate. 3, look at the color of the material The true diatom mud wall is made of inorganic pigments, so the color is natural and the color is soft and not sharp. 4, water absorption You can search for such content on the Internet: The faster the water absorption, the better the breathing function of diatom mud, and the respiratory function is the most basic function of diatom mud; if it is rarely absorbed, the diatomaceous earth content is low or diatom The micropores are blocked and their diatom mud has poor respiratory function. After spraying a small amount of water, touch it by hand. If the diatom mud is not good, it will lose powder or fade, and even mud. After the water is dry, the bad diatom mud will leave traces or fade. In fact, it is understood that the water absorption rate is not good or bad for diatom mud, because if the water absorption is too strong, the wall surface will be pulverized, which will easily cause damage to the wall surface. Moreover, the diatom mud wall surface is mainly permeable and impervious to water, which is reflected in the function of adsorption and filtration, and has certain repellency to water. 5. The surface of the diatom mud is scrubbed with a damp rag. Good diatom mud, the surface can be wiped with a damp cloth, pay attention not to scrub. Not good diatom mud, when it is wiped, the surface will appear powder or fade. 6. Squirting a diatom mud sample with a gas torch Good diatom mud can be fire retardant, heat insulation material, resistant to 1000 °C high temperature. It is hard to burn in case of fire, no smoke, no smell. Concerned about surprises Label: What is diatom mud? How to identify? Previous: The eight techniques of powder coatings are good and bad.

Dye was able to make sure the color attached to the fiber material, and easy to fall off, change color. Typically dye dissolved in water, a part of the dye Mordant dye can require adhesion to the fibers. Archaeological data show that staining technique in India and the Middle East for over five thousand years of history. Then dyes or minerals come from plants and animals, rarely treated.

Dyes are usually applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.
What is diatom mud? How to identify?
A dye is a colored substance which has an affinity for the substrate it is applied. Dyes and other materials to make fiber coloring substances, natural and synthetic sub-two categories. Dyes are colored substance. But not necessarily colored substance is a dye. Because they absorb certain wavelengths of light more than others. In contrast to dyes, pigments are insoluble, and has no affinity for the substrate. Some dyes can be precipitated with an inert salt to produce a lake Pigment, and based on the use of which may be aluminum lake, calcium lake or barium lake pigments of salt.
