All construction coatings have passed ISO9001 Paint Home News: with the improvement of living standards, environmental protection and low carbon become the trend of modern home decoration A kind of wall decoration material, called diatom mud, has become a new favorite in the home decoration market with its functions of air purification and wall self-cleaning However, the reporter visited the urban building materials market and found that there are many diatom mud brands in the market, not only the price difference is big, but also the formula is different, so it is difficult to distinguish the true and the false Each brand said that their own is the best, which makes consumers have no choice Playing environmental protection card, diatom mud is popular in traditional decoration, most of the wall materials are latex paint, wallpaper, etc With the improvement of people's awareness of health and environmental protection, green interior wall decoration materials have become the development trend of home decoration industry Therefore, traditional building materials have been transformed, with the flags of "0 formaldehyde", "anti formaldehyde", "decomposition formaldehyde" and "no addition", in order to win the favor of consumers At the same time, diatom mud, as a new high-tech decorative material, is separated from the traditional building materials by virtue of "adsorbable formaldehyde", "air purification" and other environmental protection effects in the promotion and publicity, and becomes the new favorite of home decoration "We plan to make diatom mud for the whole house To avoid decoration pollution, we need to start from the selection of materials Diatom mud is a relatively environmentally friendly material It is said that it can absorb formaldehyde, and the key price is not expensive It only costs 60-80 yuan for one square meter of contracted materials For a 100 square meter house with three rooms and two halls, it costs about 15000 yuan to make all the walls If we only make a few background walls, it costs less." Mr Li said that in the market of household building materials, many home decoration products with low formaldehyde content are made of expensive logs and solid wood, such as floors, wardrobes, cabinets, etc., which many ordinary citizens can't afford, but the price of diatom mud is relatively close to the people, so you can choose to use it in part area or in large area "From our customers' point of view, about 15% of the owners of the whole house do the decoration of diatom mud, and about 40% can choose to use the diatom mud in some areas." Mr Ma, who has been engaged in diatom mud business for nearly 10 years since 2007, said that in recent years, diatom mud has been popular with the public Mr Ma pointed out that the main component of diatomite mud is diatomite Compared with activated carbon, diatomite has 5000-6000 times more pores The surface of diatomite particles has numerous tiny pores with porosity of more than 90% This unique microstructure determines its strong adsorption effect In recent two or three years, the market of diatom mud in Weifang has been generally favored, and there have been more and more diatom mud franchised brands According to the reporter's visit, there are about dozens of diatom mud brands in the city, large and small, and the raw materials are basically produced in Jilin Province In Weifang market, in addition to several famous brands such as Dajin, green forest and quanjiamei, there are also some small brand products such as Xinya, xinjiaju and SHENTE During the interview, the reporter found that the product homogenization in some diatom mud shops is very serious The same diatom mud products with the same shape and color can be sold in several shops, but the prices are different The reporter learned that according to the recent diatom mud market, the price of diatom mud per square meter on the market varies from 50 yuan to 4500 yuan According to an industry source who did not want to be named, there are many small workshops that buy putty powder, diatomite, color paste, etc to make diatom mud by themselves "An ordinary pack of putty powder costs 10 yuan, diatomite 3000 yuan a ton, and the color paste is also very cheap, a few yuan a Jin 3% diatomite, 7% putty powder, water and color paste Workers wear masks and gloves to mix The cost of diatomite mud is much lower It may only cost 30 yuan per square meter to contract labor and materials, but such diatomite mud can not meet all environmental protection indicators, and the quality can not be guaranteed " The industry said that the formula of diatom mud is balanced The raw material of diatomite mud is mineral diatomite in the deep sea Its product formula is diatomite plus inorganic material The technical access threshold is relatively low, and there is a lack of unified and strict standards Some small manufacturers take the opportunity to enter the diatomite mud industry, relying on the mode of small workshops to produce diatomite mud and make money "As a diatom mud enterprise, if we want to do it for a long time, we should make fine products, fully let consumers know and understand it, and know how to distinguish it, so that consumers can really feel the benefits brought by diatom mud." The industry said Different brands of diatom mud have different formulations A reporter visited many stores in the city and found that many diatom mud businesses have made propaganda slogans such as "clean air", "breath and humidity", "absorb noise", "pure nature and pollution-free" When asked what kind of diatom mud is and the specific ingredients in the product, the sales staff of each brand gave different answers In a brand store of diatom mud in the new era building materials market, the reporter observed from the diatom mud packaging bag that the diatom mud ingredients of the brand mainly include diatom earth, photocatalyst, negative ion powder, etc for the specific proportion, the staff said it was inconvenient to disclose In another diatomite store, the ingredients on a diatomite bag are diatomite and zeolite "The diatomite content of our diatomite mud is 51.7%, which is produced in Linjiang City, Jilin Province." According to a salesperson of the store, diatomite content of different brands of diatomite mud and diatomite is not the same, there is no unified standard, and they are all made according to the enterprise's own standard The diatomite content of many famous brands of diatomite mud is about 50%, so the quality of diatomite mud with such content is good Diatomite mud is not judged by Diatomite Content, but by formaldehyde purification rate, 24-hour moisture absorption, 24-hour dehumidification, mildew resistance, VOC content, bonding strength and alkali resistance If the content of diatomite is too high, the bonding strength will not reach; if the content of diatomite is too low, the dehumidification index will be greatly reduced Some salesmen also said that only a proper amount of photocatalyst can make the diatom mud give full play to the role of formaldehyde decomposition In addition, some environmentally friendly gelatin can be added properly to increase viscosity and prevent slag and powder from falling There is no national standard for the moment Looking at the implementation standard of the test report for diatom mud, the staff of the standardization section of Weifang Quality Supervision Bureau said that according to the query, the current standard of diatom mud being implemented is the first national standard of diatom mud industry - "decorative wall material of diatom mud" issued on September 1, 2013, and there is no national standard The reporter looked up the relevant materials and found that the industry standard has a clear definition of diatom mud, and has made clear provisions on its usability, functionality and environmental protection This standard defines diatom mud for the first time: a dry powder interior wall decoration coating material made up of inorganic cementitious material as the main bonding material and diatom material as the main functional filler In the absence of strict national standards, in the face of such a chaotic diatom mud market, how can citizens identify the advantages and disadvantages of diatom mud products? "The best way is to choose brand products with good reputation and high reputation in the market when purchasing diatom mud." A staff member of Dajin diatom mud suggested At the same time, it is also pointed out that the diatom mud manufacturers need to have the patent certificate issued by the national building materials department or the test report issued by the national authority department, on the one hand, to ensure that the enterprises have the relevant technology and production qualification of diatom mud production, on the other hand, to provide protection for the rights and interests of consumers Therefore, when purchasing, the public can actively ask the merchants to provide relevant test reports and carefully check the test results The high-quality diatomite storage is limited, and the production process is relatively complex The diatomite mud with less than 50 yuan per square meter on the Internet or on the market is likely to be added with impurities such as lime Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
