Core tip: diatom mud is a new decorative material, which is mainly made of diatomite Although diatom mud has only developed in China for more than ten years, it is welcomed by consumers because of its natural purity, pollution-free and superior performance When consumers face a wide range of diatom mud in the market, how should they distinguish it? Let's understand the real face of diatom mud from the definition and function of diatom mud A detailed explanation of the diatom mud Encyclopedia (picture source network) I The newly implemented standard of diatom mud decoration wall materials for the first time Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Coating House News: diatomite mud is a new decorative material, which is mainly made of diatomite Although diatomite mud has only been developed for more than ten years in China, it is welcomed by consumers because of its natural purity, pollution-free and superior performance When consumers face a wide range of diatom mud in the market, how should they distinguish it? Let's understand the real face of diatom mud from the definition and function of diatom mud To reveal the true features of the diatom mud in Lushan Mountain and to explain the Encyclopedia of diatom mud (picture source network) I The newly implemented standard of the diatom mud decorative wall materials first gave a clear definition to the diatom mud, indicating that the diatom mud is a dry powder interior wall decorative coating material prepared with inorganic cementitious material as the main binding material, diatom material as the main functional filler 1 Although the binding material of diatom mud is specified to use inorganic cementitious material as the main binding material (including white cement, gypsum, white lime powder, etc.), due to the consideration of construction performance, organic additives can also be added appropriately, but the volatile organic compounds (VOA) cannot exceed the standard 2 The product needs to be able to detect diatomite standard also stipulates that diatomite products need to be able to monitor diatomite composition, which is made for some manufacturers to add lime powder or glutinous rice powder and other materials in diatomite mud, and pretend to be diatomite However, the specific content of diatomite is not clearly defined Some experts explained that the specific content was not marked because if diatomite composition can be detected in unit quality products, it means that it accounts for at least 10%, which meets the basic requirements 3 Diatomite diatomite is the core part of diatomite mud products, which is formed by the deposition and fossilization of marine plankton diatom living millions of years ago Diatomite is a porous structure with many pores The special structure of this mineral determines that diatomite mud has strong respiratory permeability and adsorption However, the permeability and adsorption of respiration can make diatom mud absorb and decompose formaldehyde and other harmful substances 2、 In the past, due to the lack of industry standards, many enterprises in the market hyped the concept of diatom mud, exaggerating the function of diatom mud wantonly, so that consumers could not correctly understand diatom mud And the diatom mud industry standard also made clear provisions for its basic functions It is stipulated that the diatom mud shall meet the requirements of usability, decoration, functionality and environmental protection 1 First of all, diatom mud must have a certain bond strength Therefore, inorganic cementitious substance must be added to the material Secondly, the product also needs to have certain temperature and humidity resistance It is mainly to ensure that the diatom mud will not age or fall off after periodic temperature and humidity changes in the actual use environment 2 The color of decorative diatom mud is mainly achieved by adding natural inorganic pigments, and its texture pattern can be made by a variety of tools and techniques Diatom mud has strong plasticity and can produce a variety of texture effects 3 In the functional market, many businesses will blow the function of diatom mud to the gods when selling In this standard, the specific functions of diatom mud are clarified and quantified Diatom mud has good performance in formaldehyde purification, mildew prevention, antibacterial and humidity regulation The standard has made quantitative regulations on the humidity regulation performance, formaldehyde purification performance, effect durability and mildew resistance of diatom mud Because diatom mud has a good respiratory performance When the air humidity is high, it can absorb part of the water in the air, and when the air is dry, it will release part of the water to regulate the indoor humidity Therefore, it focuses on the subdivision of the humidity regulation performance 4 Environmental protection diatomite itself does not contain formaldehyde, benzene series and other harmful substances, but after adding other substances to make diatomite mud, its environmental protection is not necessarily up to standard The new standards strictly limit the limit of harmful substances The standard points out that the harmful substances are lower than the detection limit, that is, the content of volatile organic compounds is less than 1 g / kg; the sum of benzene, toluene, ethylbenzene and xylene is less than 50 mg / kg; the free formaldehyde is less than 5 mg / kg; the soluble heavy metal is less than 10 mg / kg 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,
