Coating knowledge: inside of diatom mud industry, how many consumers are "bullied"

Core tip: in the past, latex paint and wallpaper were popular for decoration, but now diatom mud is popular Did you use diatom mud? Diatom mud is gradually put on the shelves in major building materials cities across the country, causing many consumers to stop But at present, the domestic diatom mud market is not mature enough, the diatom mud standard is just launched, and the industry is not standard enough; especially the price is from hundreds to thousands of yuan, the industry insiders are confused, and the consumers are more confused 1、 Diatom mud scrub resistant? First of all, understand what kind of diatom mud scrub resistant, why scrub resistant The reason given by the consumer is very simple It's easy to take care of it when it's dirty The reason seems reasonable, but there are some questions Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: in the past, latex paint and wallpaper were popular for decoration, but now diatom mud is popular Did you use diatom mud? Diatom mud is gradually put on the shelves in major building materials cities across the country, causing many consumers to stop But at present, the domestic diatom mud market is not mature enough, the diatom mud standard is just launched, and the industry is not standard enough; especially the price is from hundreds to thousands of yuan, the industry insiders are confused, and the consumers are more confused 1、 Diatom mud scrub resistant? First of all, understand what kind of diatom mud scrub resistant, why scrub resistant The reason given by the consumer is very simple It's easy to take care of it when it's dirty There seems to be nothing wrong with this reason, but there are some problems From a technical point of view, it is easy to solve the problem of scrub resistance It can be completely realized by adding a strong alkaline mineral binder and an appropriate amount of chemical binder The same is true for paint products Generally speaking, scrub resistant latex paint is a good quality emulsion It is not difficult in technology to achieve scrub resistance The problem is that the result of blind pursuit of scrub resistance is that the respiratory performance of diatomite is greatly reduced, which is manifested as poor respiratory performance, which is the water absorption emphasized by many manufacturers Because the addition of strong alkaline substances and excessive binders causes the "pore blocking" phenomenon of diatomite, what is the significance of such diatomite mud? Secondly, the original ore color of diatomite mud is the earth color of diatomite mud, so it is called "diatomite mud" because of its main active ingredient "diatomite" Diatomite is a mineral name, evolved from the remains of ancient diatoms Its main component is opal The natural diatomite is buried in the structure of the ore bed Because of its porous adsorption, it contains a lot of impurities The purified diatomite is white, light yellow and light gray Only the raw diatomite ore containing a large number of unknown impurities will have color These impurities block the breathing hole of diatomite, not only lose the breathing function, but also produce new pollution Diatomite itself is not rare, but the advanced diatomite which can be used to make diatomite wall material is very limited, which is determined by the difficulty of purification and the purity of the finished product Some manufacturers use the raw material of raw diatomite which contains a lot of impurities Although it has "natural" color, the activity of diatomite is almost zero, and various heavy metals and other substances in the impurities will become potential killers of health Under the guise of "raw ore color" and "natural color" of diatom mud, in fact, the inferior products with great risk are sold, which deserves our attention 3、 The use of diatom mud can completely solve the problem of indoor pollution It is a very good indoor functional and decorative wall material product For this, Xiaobian agrees with it very much Because of this reason, diatom mud products are loved by consumers But it should be pointed out that diatom mud should not be used as a panacea to solve indoor air pollution The selection of interior decoration materials should start from a little bit, at the same time, we should pay attention to the selection and use of other building materials For example, try to avoid using inferior paint, wallpaper, furniture, wood, etc., especially try to avoid purchasing and using inferior melamine board furniture 4、 Diatom mud refers to "mud" in a very rough way The first reaction in many people's minds is the rough mud composed of sand It seems that only the similar "diatom mud" is true, and those very delicate ones must be fake, or fake by putty powder It is true that some small workshops use ordinary putty powder or similar products to pretend to be diatom mud, but it is a big mistake to judge whether diatom mud is true or not based on the thickness of products Diatomite is the main raw material of diatomite, but pure diatomite can not be used as building materials directly on the wall Besides diatomite, there are many other inorganic fillers in diatomite Whether diatomite or inorganic filler, there are different choices of coarse material and fine material If diatomite uses fine material and filler also uses fine material, the finished diatomite mud will not be rough, but it still has all the characteristics of diatomite mud On the contrary, if a product does not use diatomite, but uses a lot of coarse fillers, the final product will be very rough, but it is completely "fake" diatomite mud Some businesses propagandize that "only rough surface can have the function of absorbing moisture and removing aldehyde", which is even more nonsense The functionality of diatomite is realized by molecular micropores invisible to the naked eye, which has nothing to do with whether the surface is rough or not It's just an excuse to fool consumers to say that only rough can have functionality 5、 Good diatomite mud has slight desalting phenomenon The reasons given by some manufacturers are very simple The existence of desalting phenomenon is caused by the lack of binder or the lack of binder In other words, there is slight desalting because the content of diatomite is much higher than that of ordinary products If this reason is true, let's think about the fact that the wall of diatom mud is seriously de powdered, light will pollute clothes, and heavy will cause dust to enter our respiratory tract and lungs with the air, causing chronic respiratory disease or pneumoconiosis If so, what's the meaning of purchasing such diatom mud? 6 When water forms mud, it's the real diatom mud Some enterprises advocate that diatom mud should meet water to form mud and have the characteristics of mud, which is diatom "mud" This is a complete deception and deception of consumers When it comes to water, it seems natural at first, but it is actually the product with the worst quality Under the erosion of water vapor in the air, the surface of this kind of diatom mud will decompose and fall off, and become silica floating in the air, which may cause asthma or even silicosis, hiding a huge potential safety hazard As a kind of building material, while pursuing natural environmental protection, it must be able to meet the most basic safety problems It's as if we can no longer pursue nature, or risk being infected by bacteria and parasites to eat raw meat, or pursue nature, or go back to the primitive society to live a high-risk life of drinking blood The so-called "mud" of diatom mud is just a common name, not the real performance of its performance Over demanding this mud like nature may fall into the "trap" carefully prepared by businesses 7、 The pH of diatom mud products has nothing to do with themselves Many consumers will think that whether diatom mud is strongly alkaline or weakly alkaline has little to do with themselves, which is actually a wrong point of view Strong alkaline diatom mud will cause different degrees of damage to the construction personnel, and it is also the main cause of the desquamation and color of diatom mud, which can not be said to have nothing to do with it Some diatom mud products will not desmear just after construction, but after a few days, there will be continuous desmear phenomenon caused by strong alkali In addition, in rainy days and at low temperature, the appearance of color is also due to the strong alkali The phenomenon of flower color is actually the problem of Pan alkali Concerned about the WeChat official account, "paint net" There are some surprises to be observed If the swallow and the Wu Mei Niang sell paint, what will happen?
