structure
The main raw material of diatom mud is diatom earth, a diatom mineral formed over hundreds of millions of years. Diatoms are algae that live in oceans and lakes. Oceans and lakes are the hometown of algae. There are many kinds and quantities of diatoms here, which are called grasslands in the ocean. They produce 70% of the oxygen on which life on earth depends, and are the real cradle of life on earth. Diatom mud is a natural substance deposited by diatom, which is an aquatic plankton that lived millions of years ago. Its main component is opal, which is rich in many beneficial minerals. Its texture is light and soft. Electron microscope shows that there are numerous micropores on the surface of its particles, with porosity of over 90% and specific surface area of up to 65m2/g/g. It is this prominent molecular sieve structure that determines its unique function-strong physical adsorption and ion exchange performance. Spraying water on a large area of the wall can absorb a lot of water, indicating that it has strong adsorption capacity, slowly and continuously releases negative oxygen ions, and can effectively decompose harmful carcinogens such as formaldehyde, benzene and radon.
Diatoms are a large group of eukaryotic algae. One of the main characteristics of diatoms is that diatom cells are covered with siliceous (mainly silica) cell walls. The structure and morphology of siliceous cell walls are different, but most of them are symmetrically arranged. This arrangement can be used as the basis for classification and naming. But this symmetry is not completely symmetrical, because one side of diatom cell wall is slightly larger than the other, so that it can be embedded together. Fossil remains show that diatoms originated in the early Jurassic at the latest. Only the male gametophyte of the central diatom has flagella and can swim. Diatoms have always been an important indicator species for environmental monitoring and are often used in water quality research. Classified as a class, it has jurisdiction over central diatoms and pinnate diatoms.
Consumers should pay attention to the identification of true and false diatom mud, and spray a lot of water on the diatom mud wall with a watering can. It is true that diatom mud is not colorful and does not flow. Touch the wall with your hand, it's dry. False "diatom mud" has pungent smell or tasteless after spraying water. In short, the phenomena of not absorbing water, absorbing less water or absorbing water to form mud, slag, color, decoloration and discoloration are all fake "diatom mud".
function
Diatom mud itself is pollution-free, pure natural and multifunctional, which is incomparable to traditional coatings such as latex paint and wallpaper. Use diatom mud to decorate without moving, because there is no smell in the construction process, it is pure natural and easy to repair.
Purify the air and eliminate peculiar smell.
Advantages:
Diatom mud itself is pollution-free, pure natural and multifunctional, which is incomparable to traditional coatings such as latex paint and wallpaper. Use diatom mud to decorate without moving, because there is no smell in the construction process, it is pure natural and easy to repair. Purify the air and eliminate peculiar smell.
Disadvantages:
The surface strength of diatom mud is relatively low, so it can't receive a big impact.
Diatom mud products have a unique "molecular sieve" structure and powerful physical adsorption and ion exchange functions, which can effectively remove harmful substances such as free formaldehyde, benzene and ammonia in the air, as well as odors generated by pets, smoking and garbage, and purify indoor air.
Fire and flame retardant
Diatom mud is made of inorganic materials, so it does not burn, and even if there is a fire, it will not emit any smoke harmful to human body. When the temperature rises to 1300℃, diatom mud only appears in a molten state, and no smoke such as harmful gas is generated.
Breathing and humidity regulation
With the change of ambient air temperature in different seasons and in the morning and evening, diatom mud can absorb or release water, and automatically adjust indoor air humidity to achieve relative balance. Especially in coastal cities and cities with humid air in the south, the effect of adjusting indoor air humidity is obvious, which reduces the troubles caused by air humidity.
Sound absorption and noise reduction
Because of its porous molecular structure, diatom mud has a strong noise reduction function, which can effectively absorb high-frequency sound bands harmful to human body and attenuate low-frequency noise. Its effect is equivalent to more than twice that of cement mortar and slate with the same thickness, and at the same time, it can shorten reverberation time by 50%, greatly reduce the harm of noise to people and create a quiet sleeping environment for you.
thermal insulation
Diatomite, the main component of diatom mud, has low thermal conductivity and is an ideal thermal insulation material with excellent thermal insulation performance, and its thermal insulation effect is six times that of cement mortar with the same thickness.
Release negative oxygen ions
Diatom mud has a unique "molecular sieve" structure, which will produce a "waterfall effect" when it comes into contact with moisture in the air, thus continuously releasing negative oxygen ions beneficial to human body.
dustless
Does not contain any heavy metals, does not generate static electricity, floating dust is not easy to attach, the wall is permanently fresh, diatom mud is not easy to generate static electricity, and the wall is not easy to fall off dust.
subdued colour
Diatom mud is colored with inorganic mineral pigments, and the color is soft. People live in a room coated with diatom mud, and the light reflected from the wall is naturally soft, so people are not prone to visual fatigue, which effectively protects your vision and that of your family, especially children. At the same time, the color of diatom mud wall is durable, and the high-temperature coloring technology is adopted, which does not fade, and the wall is as good as new for a long time, which increases the life of the wall, reduces the number of wall decoration and saves the room cost.
material characteristics
Features: 1: the color is uniform and muddy, colored at high temperature, and it does not change color after a large amount of water spraying, without mud, and it has the effect of natural mud by gently pressing with the palm of your hand.
Feature 2: powder, mixing and construction are odorless, and no harmful substances are released.
Feature 3: Fine texture and fine sand grains, suitable for construction on flat and dry indoor walls.
Feature 4: Absorbs water, does not burn in case of fire, and has no irritating smell.
special technology
The technology of diatom mud completely solves the problems of decoration pollution and indoor pollution that are difficult to solve all over the world, so that people can enjoy fresh air and negative oxygen ions without leaving home. Diatoms have been deposited and mineralized for hundreds of millions of years to form diatom minerals, the main component of which is opal.
Molecular sieve structure of diatomite
Soft and porous. Electron microscope shows that diatom mineral is a kind of nano-porous material (micropore diameter is about 0. 1-0.2 micron), the porosity is as high as 90%, and it is arranged in regular circles and needles, and the number of micropores per unit area is several thousand times more than that of charcoal. Outstanding molecular lattice structure features determine its unique function. Diatom minerals have strong physical adsorption and ion exchange properties, and are widely used in alcohol and medical injection filtration, food additives, nuclear radiation adsorbents and many other fields after finishing. Diatom precipitates to form diatom mineral-diatomite.
Development history
With the continuous improvement of people's health requirements in China, more people begin to pay attention to improving indoor environment and reducing decoration pollution. Many families use so-called new building materials, and the formaldehyde detection of a single building material does not exceed the standard, but a variety of building materials produce formaldehyde superimposed pollution. Diatom mud is pure natural, which can completely eliminate indoor formaldehyde. Diatom mud can adjust humidity and temperature, reduce the utilization rate of air conditioners and deodorants, protect the atmosphere, save energy and create a comfortable living space. Because there are many disadvantages in traditional decoration methods, various problems have arisen, such as:
1, mildew and deterioration of building materials caused by humidity in the building.
2. Dry indoor air causes cracking and deformation of building materials and furniture.
3. Indoor air affects the health of residents, such as wheezing, reactive dermatitis, nervous and digestive diseases, and even cancer.
building technology
Traditional and complete diatom mud is composed of three elements: raw materials, props and construction methods. Materials are carriers, props are devices, and construction methods are rules. The combination of the three, while giving vivid expression to the wall, finally reveals and expresses the life taste and value orientation of "people". As a wall technology, mud is not only a material, it is being passed down and carried forward with its "cultural" connotation, bearing unlimited personal sustenance and self-appeal.
1, stirring
Add clean water accounting for 90% of the construction water consumption into the mixing container, then pour in diatom mud dry powder to soak for a few minutes, and then stir with an electric mixer for about 10 minute. At the same time, add 10% clear water to adjust the construction viscosity and mud paint, and fully mix well before use.
Step 2: Apply
Two times: the first time in Tu Ping is about 1 mm, about 50 minutes after completion (depending on the site climate, it is advisable to keep the surface non-sticky to prevent exposure, and fill it with materials), and the second time is smoothed (the thickness is about 1.5 mm).
The total thickness is between1.5mm and 3.0mm. ..
3. Texture pattern making
After the second application is completed, grasp the drying time according to the actual environmental drying situation, and make the texture pattern according to the construction method.
Step 4: Collect light.
After finishing the texture pattern, compact it with a light trowel and collect light along the pattern grain.
Product procurement
Purchase logo
1, before buying, it is best to shop around and learn more about diatom mud products. We should carefully identify the products. For products with different brands and different packaging, we should comprehensively consider quality, price, service and corporate reputation. Real diatom mud is easy to identify. 1 m2 of wall surface, 1 min absorbs about 1 kg of water, which is not colorful or muddy. A watering can verifies the authenticity.
2. As a new type of functional interior decoration wall material, diatom mud has many brands. When purchasing, you should pay attention to the following points:
I. Functionality:
The adsorbent diatom mud itself has numerous micropores, and its unique molecular sieve structure determines its powerful physical adsorption and ion exchange functions. Water is pervasive, so it can be identified by spraying water (absorbing water). Repeatedly spraying water 20~30 times at the same position on the wall with a big watering can, the true diatom mud will absorb water quickly, and it can absorb water 1 kg per square meter of wall, while the false diatom mud does not absorb water or absorbs water very little.
B, decorative, natural and simple texture pattern.
C, durability for 30 years, no fading, no pulverization, no slag, no peeling, etc.
D, environmental health and environmental protection, zero formaldehyde, zero pollution and zero VOC.
shopping tips
Look at the color first. The real diatom mud is soft in color, evenly distributed, matt in color and has the effect of mud surface. Fake diatom mud will be shiny, too bright in color, and have a dazzling feeling. It is easy to decolorize and have patterns after long-term use.
Second, try to feel. The real diatom mud feels delicate, has the feeling of pine, the texture pattern is delicate, smooth and generous, and the artistic impact is strong. Fake diatom mud feels rough and hard, like cement and sandstone, and the texture pattern is hard and beautiful.
Third, look at water absorption. Because the real diatom mud has the characteristics of porosity and molecular sieve structure, it is proved that it has rich pores by spraying water on the wall of diatom mud. Holding a 2-liter watering can, spray water on the diatom mud wall repeatedly, and the water on the real diatom mud wall will be quickly absorbed. Touch the spray wall gently with your palm, and the palm will not be stained, muddy, discolored or shed, and it will also emit a faint earthy smell. After the fake "diatom mud" wall is sprayed with water, the water will flow down the wall, and the water absorption is too small to be repaired. In addition, the fake "diatom mud" has a pungent smell after spraying water, or it is tasteless because of the solidification of glue.
Wall cleaning
1, small handprints, footprints or handwriting cleaning methods Because children like to play, it is inevitable that some handprints will be left on the wall. You can try the following methods to clean them:
Answer: Gently wipe the dirty diatom mud wall with simple tools such as soft rubber, hard rubber or fine sandpaper, and it will be removed slowly without leaving any traces.
2. Cleaning methods of dust hanging and dust collection The dust hanging on the wall is generally caused by too dry air and electrostatic adsorption of floating dust. Because diatom mud has a good balance effect on air humidity, and the surface of the wall material is hydrophilic, which can effectively reduce the static phenomenon, so compared with other decorative materials, diatom mud wall is less likely to hang ash and has a certain self-cleaning function.
3. Colored liquids such as coffee and orange juice.
Answer: Clean the stain before it permeates and spreads. Lighter stains can be removed by gently wiping the dirty diatom mud wall with a clean rag stained with chlorine bleach.
B: If it has permeated and spread, and the stain is large, it is necessary to scrape off the polluted mud gently, and then daub it again with the same diatom mud and reshape it according to the original texture.
C If it is really necessary, it can be partially wetted with water, removed and mended. This process needs a professional master to complete.
technology standard
China's building materials industry standard "Diatom Mud Decorative Wall Materials" (JC/2 177-20 13) may be officially implemented on September 1 day. This standard mainly specifies its usability, functionality and environmental protection. This standard is the most basic criterion and the threshold for most enterprises to enter. The state encourages scientific and technological innovation.
Diatom mud is "a dry powder coating for interior wall decoration with inorganic gel as the main bonding material and diatom as the main functional filler". The standard-setting unit has no requirement for the content of diatomite, so consumers should pay attention to identification when purchasing.
The main components of the product are defined clearly, so that consumers can clearly understand what kind of material diatom mud is. Another key point in the standard is to clarify the content of diatomite in diatom mud products. According to the standard, diatomite is the main component, and the content of diatomite is very high.
"As a functional wall material, diatom mud needs to meet four requirements: usability, decoration, functionality and environmental protection. In the standard, most of the above performances are also clearly defined. " According to industry insiders, the diatom mud market is expected to be more standardized, and consumers should pay attention to identifying the quality of diatom mud.
The reporter reminded consumers that when buying diatom mud products, all kinds of statements against businesses should be confirmed by asking for corresponding test reports. Consumers must carefully distinguish when buying diatom mud, compare the contract content with the actual construction effect, and make experimental comparison. The general identification method is that it absorbs in water, does not burn in fire, and has no irritating smell.
