Diatomite can play the role of deodorant
May 11, 2018

The research results of the Kitami Institute of Technology in Japan show that the indoor and outdoor coatings and decorating materials produced by diatomite will not give off harmful chemicals to the human body, but also improve the living environment.

First, the indoor humidity can be automatically adjusted. The main component of diatomite is silicic acid, which is produced in indoor and outdoor coatings and wall materials with super fiber and porous properties, and its super micro pore is 5000 to 6000 times more than that of charcoal. When the humidity in the room rises, the superfine pores on the wall of diatomite can automatically absorb the moisture in the air and store it. If the water content in indoor air is reduced and humidity is decreased, diatomite wall material can release the moisture stored in the superfine pores.

Secondly, diatomite wall material also has the function of eliminating peculiar smell and keeping indoor clean. Research and experimental results show that diatomite can play the role of deodorant. If titanium oxide is added to the diatomite to make a composite material, it can eliminate the odor and absorb and decompose harmful chemicals for a long time, and can keep the wall surface clean for a long time. Even if there are smokers at home, the wall will not be yellow.

Third, the research report believes that diatomite decoration materials can also absorb and decompose substances that cause human allergy and produce medical effects. The absorption and release of moisture from diatomite wall material can produce waterfall effect and decompose water molecules into positive and negative ions. Because the water molecules are wrapped up to form a group of positive and negative ions, and then water molecules as the carrier, floating around in the air, has the ability to kill bacteria. The positive and negative ions that float around in the air meet with allergic substances and other harmful substances such as bacteria and mold. They can immediately encircle and isolate them. Then, the most active hydroxyl ions in the positive and negative ions group react violently to these harmful substances. Finally, they are completely decomposed into harmless substances such as water molecules.

The use of diatomite added to paint for extinction and odor absorption has been applied abroad for many years. Domestic enterprises have gradually realized the excellent performance of diatomite used in coatings and diatom mud.

The indoor and outdoor coatings, decorating materials and diatom mud produced with diatomite will not only give off harmful chemicals to the human body, but also improve the living environment.

Diatomite coating, after adding diatomite, has been widely used by many large paint producers in the world as designated products, widely used in diatom mud, latex paint, internal and external wall coatings, alkyd resin lacquers and polyester lacquers, especially for the production of architectural coatings. In the application of paint and paint, it can control the gloss of the surface of the film evenly, increase the wear resistance and scratch resistance of the coating, dehumidification, deodorization, and clean air, sound insulation, waterproof and heat insulation, and good permeability.

Diatomite is a siliceous rock, and the siliceous rocks are divided into two major categories: biological or biochemical genesis, diatomite, plate diatomite, protein soil, radiolarian, and cavernous rock.

Abiotic origin (chemical, volcanic, secondary origin) - Jasper, chert, siliceous and quartzite.

The main associated minerals in diatomite are clay minerals and charcoal (organic matter). When the content of these minerals is more than 50%, it belongs to clay and carbonaceous shale and is named diatom XX rock at the time of naming. When these minerals are less than 50%, they belong to diatomaceous earth, named XX diatomite.
