Selection of diatom mud: look, spray and smell three ways to identify high-quality diatom mud

Core tip: unconsciously, diatom mud has entered thousands of households As a new type of environmental protection material, how to choose a really good diatom mud? Experts say that we can recognize it by seeing, spraying and smelling First, look at qualifications The diatom mud manufacturer shall have the patent certificate issued by the national building materials authority or the test report issued by the national authority, that is to say, the diatom mud shall have a legal "identity" On the one hand, it is to ensure that enterprises have the relevant technology and production qualification of diatom mud production, on the other hand, it also provides a basis for the protection of consumers' rights and interests Second, "water spray" experiment high quality Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: unconsciously, diatom mud has entered thousands of households As a new type of environmental protection material, how to choose a really good diatom mud? Experts say that we can recognize it through one look, two sprays and three smells First, look at qualifications The diatom mud manufacturer shall have the patent certificate issued by the national building materials authority or the test report issued by the national authority, that is to say, the diatom mud shall have a legal "identity" On the one hand, it is to ensure that enterprises have the relevant technology and production qualification of diatom mud production, on the other hand, it also provides a basis for the protection of consumers' rights and interests Second, "water spray" experiment The high-quality diatomite decorative products can retain the microporous structure completely and retain the strong water absorption performance even if they are continuously sprayed with high-pressure water kettle, because the formula of diatomite is reasonable and there is no need to use any glue medium in the process of wall mounting Third, smell the peculiar smell The diatom mud material with good quality will not emit any peculiar smell during construction, and will not produce some volatile substances such as formaldehyde It is a real green wall material with zero pollution Recommended reading: what are the disadvantages of diatom mud? In addition, the insiders also pointed out that the price of brand diatom mud is mostly high, which is determined by the scarcity of main raw materials - diatomite The storage of high-quality diatomite is limited, and the production process is complex, so the price is slightly higher than that of latex paint and wallpaper If consumers encounter the "diatomite mud" whose price is too low, they should be careful to purchase it The diatom mud sold on the Internet for only tens of yuan and one square meter is likely to be added with impurities such as lime The identification method is also very simple: dissolve it in water, use the pH test paper to measure it, and it will be known that the real diatom mud is neutral, and the one added with lime is alkaline Among various brands, it is also "pinching" Some brands say that adding photocatalyst can make diatom mud give full play to the role of formaldehyde decomposition; However, other brands said that diatom mud with high purity can release negative oxygen ions, which can decompose and adsorb formaldehyde well without chemical additives, and claimed that "chemical additives will block the gap of diatom mud, and also release formaldehyde, leading to secondary pollution." What's more confusing is that some interviewed brands such as "Dajin" and "quanjiamei" said that as long as the real diatom mud can be scraped down and reused, otherwise it is mixed with putty powder or shell powder However, brands such as "clossway" say that their diatom mud can not be reused after it is put on the wall, because it is pure natural without preservatives, and will deteriorate and produce bacteria and stink after adding water Recommended reading: how to select real high-quality diatom mud?
