Diatom mud decorative wall material of the unique features of multiple environmental health to become the impudently heartfelt of decorative building materials market, a unique decorative effect has gained more than and more users of all ages.Paints and goals involve diatoms diatom mud. Diatoms paint is added to a conventional rubber-base paint or oil paint in a certain portion of diatomaceous hide to impart regulate humidity, sub merging of harmful gases to mend affection and abrasion resistance more features and so on. Diatom mud is diatomaceous earth as the main raw material, adding a variety of additives made of powder coatings. Diatom mud is China in recent years, emerging as a utilitarian interior decoration environmentally friendly materials, with humidity control, air purging, awake retardant, acoustic make noise reduction, thermal insulation and protection of eyesight, self-cleaning walls and new(prenominal) features. Diatom mud is not only versatile, but also give notice make a variety of color texture, rich styling, style, complete, so the diatom mud introduced into China on the button a few years it has developed rapidly, the majority of customers and recognition.Diatom mud is a new natural green paint, latex paint and wallpaper to stand in for villas, hotels, offices, apartments, hospitals and other interior decoration. Since the body of water resistance is poor, not much menses is a pplied to the external walls. Diatomaceous earth from fossil marine diatom algae plants create after millions of years, the main comp geniusnt of opal and its variants, followed by clay minerals.Diatomite grownup molecular lattice structure determines its unique features, it has a strong natural adsorption and ion exchange properties, after finishing wide employ operational coatings, pharmaceutical aid, fare additives, nuclear radiation adsorbents and other fields. Diatomaceous earth is a siliceous sedimentary rock, mainly in China, the US, Denmark, France, the former Soviet Union, Romania and other countries.Figure.1 Diatomite SEM photographThe Proposed MethodologyDiatom mud decorative wall material.Diatom mud is mainly comprise of in constitutional cementitious materials, diatom operational fillers, pigments and other accompaniment materials. Currently diatom mud wall decoration materials market mainly dry out powder coating material was stirred when such products into m easureized construction of water sludge, referred to as diatom mud. and more to scratch, wiping construction methods, mainly by its available features added fillers decision.Diatomite features.The main function of the material as diatomaceous earth is a biogenic siliceous sedimentary rock, the ocean or lake grown diatoms creatures submerged debris deposited by a non-metallic mineral natural environment and evolving role.The main component of diatomaceous earth is amorphous SiO2, followed by minerals, but also contains some organic matter. SiO2 content is one of the diatoms content measurement flag diatomaceous earth ore.Diatomaceous earth be excite of its unique structural features and a delicate, loose, light, porous, absorbent and strong perceptivity properties and diatomaceous earth and the physical characteristics of both the chemic composition, but also with algae are composed of mineralization environmental conditions and directly affect the diatomite applications. These properties include the color, physical properties, specific gravity, bulk density, melting point, particle size, pore size, and some applications also need to consider the specific surface area and porosity.Since diatomite unique porous structure and excellent absorption properties, making diatom mud decorative wall material combines the unique features of environmental health.It features diatom mud decorative wall material.Diatom mud decorative wall material is the use of diatomaceous earth having a delicate, loose, light, porous, absorbent and permeability and other characteristics, with the traditional interior decoration materials combined to produce both decorative effect and environmental health function decorative building materials. Diatom mud has the following characteristics.The humidity slaying. by and by the film-forming diatom mud coating the interior has a porous structure, when the indoor air relative humidity is too high, the air desiccation pressure to a higher (prenominal) place the saturation vapour pressure of diatoms wall material surface raft concave surface water on this when water vapor is adsorbed, the desorption and vice. By water vapor absorption, release, efficaciously regulate the indoor air relative humidity values, so that control in the appropriate range of charitable health, improve indoor air quality, good living environment.Purifying air. civilization function is also porous channel structure is based on the adsorption of free capture odor molecules in the air, formaldehyde, benzene, volatile organic compounds and a variety of substances. Add the appropriate preparation process nicety materials, odor molecules adsorbed molecules rapid decomposition of harmful substances, and indeed achieve the place of purging the elimination of hazardous substances, keep indoor air raw and clean. Diatom mud has a unique molecular sieves structure, not only can absorb moisture in the air can be effectively adsorbed in the air f ree of formaldehyde, benzene and other harmful chemical substances and odors from smoking, garbage, pet excretion produced thereby to purify indoor air purposes. This is similar to the physical adsorption of activated carbon, but also has the effect of chemical decomposition. Physical adsorption diatom mud is a quick process, but a slow chemical decomposition. Specific reaction process is as follows2HCHO + O2 = 2HCOOH2HCOOH + O2 = 2C O2 + 2 body of waterC O2 + H2O + Ca2 + = CaCO 3 + 2H +2HCOOH + Ca2 + = Ca (HCOO) 2 + 2H +Ca (HCOO) 2 + O2 = CaCO3 + H2O + CO2 Anti-condensation. Indoor relative humidity stays high, the construction of the wall is easy to produce condensation, having a high level of humidity cognitive process diatom mud decorative wall material can be expeditiously adsorbed water vapor molecules and water molecules inside a high efficiency reservoir to remove the accumulated surface excessive water vapor molecules to prevent surface condensation.Antibacterial and a nti-fungal. Diatom mud decorative wall material can effectively absorb water vapor adhering to the surface, eliminating mold, bacteria addition environment from the source, in addition to effectively suppress and destroy the issue of mold. Some diatom mud products tend to add a certain kernel of antimicrobial agent, in order to achieve efficient antibacterial effect sterilization.Protect eyesight. Diatom mud porous surface, which will help generate diffuse, effectively reduce the refractive index of the light, so soft colors. Diatom mud coating the room, the walls reflects light naturally soft, not easy to cause visual fatigue, can effectively protect the eyesight, especially for the protection of eyesight effect is remarkable. The paint surface is flat as a mirror, tend to have higher gloss, refractive index of light is strong, so sharp colors, good leave to visual fatigue, damage eyesight.Acoustic noise reduction. Diatom mud itself porous, with strong noise reduction function , can effectively absorb harmful high relative frequency sound segments, and low frequency noise attenuation. Its effectiveness is equivalent to the uniform thickness of the stone or cement mortar 2 to 3 times. At the same time can be reduced al close 50% of the reverberation time, significantly reduce the noise on the gentlemans gentleman body, it is also more suitable for diatom mud railway station and residents devout the plant and the use of mechanical units, diatom mud will create a restful nights sleep or working environment.Self-cleaning walls. Diatom mud is mainly composed of an inorganic material SiO2, does not produce static electricity, dust easily attached to the surface. Even among texture or pattern fall into the dust, it is in truth easy to remove with a feather duster, for hand writing footprints and can be erased with a rubber lightly, as the new abiding wall. picture animated image.In the early development of Chinas animation industry, folk art is widely appl ied to the design of the animated image, and achieved good results. Folk art in China has a very long history, from the Dunhuang murals to the Han Dynasty brick, paper cutting from northerly Shaanxi to Tianjin clay figurines, paintings from Weifang to Shengzhou Shaoxing opera, are forms of folk art. In addition, the design of the characters also has a very rich experience, these design experience and skills for animated image designs, has a very good reference guide, which is the most typic drama. Theatre is one of the widely popular folk art form of folk art in terms compared to other, more emphasis on characters design, which is the most typical mask and clothing.Building materials and good requirements.Diatom mud good characteristics of the product, this stock(a) provides technical requirements diatom mud decorative wall material includes a total of trio parts, namely, the general technical requirements, functional requirements and technical requirements of harmful substance s.General technical requirements which include nine state indicators, workability, appearance of the coating, the initial drying crack resistance, dry time, alkali resistance, adhesive strength, resistance to temperature and humidity performance and diatoms and other ingredients functional technical requirements include The humidity performance, formaldehyde adsorption properties, formaldehyde improve effect lasting performance, anti-fungal and anti-5 performance indicators mold durability, etc harmful substances required to pick up volatile organic compounds, benzene, toluene, ethylbenzene, xylene sum of free formaldehyde and alcohol-soluble heavy metals.Application Status diatom mud. Diatom mud as a new type of environmentally friendly materials, in the form of mud is replace wallpaper, paint and other traditional interior decoration materials, its production and use have great prospects for development.Japan long ago diatom mud has been use in the construction industry. In th e 1960s, Japan supplies scholars began to conduct functional studies diatom mud, diatom mud soon as a new functional building material are widely used. In 1980, the study of environmentally friendly building materials concern environmental protection experts, diatom mud function once once more scientists deepen the study, after selection and processing of mineral products diatoms used as a filter aid and adsorbent materials, used in food umpteen areas of medicine, daily chemical, nuclear waste and sewage treatment, such as the production of beer filtration, water purification, medical injections and blood plasma filtration, beauty armorial bearing products manufacturing and so on.Test methods and index.According to various architectural coatings, interior paint footrace method specified in the standard functions of the technical indicators at home and abroad, combined with interior decoration diatom mud wall material characteristics practiced indicators refer to the make iting domestic and international examen methods and standards, finalized the present standard of the technical requirements and test methods.Diatoms ingredients.Diatom mud decorative wall material think why the name diatom mud, diatom is because it mustiness function as the main material, and thus comprise one diatom diatom mud decorative wall material must have the basic characteristics.Different manufacturers diatom mud formulations on the market vary, many of the components added to the decimal analysis of the product a great deal of difficulty. The most commonly used quantitative analysis of diatom test methods are roentgenogram diffraction (XRD) phase analysis and chemical methods, when used diatom mud product analysis, testing error caused due to complex composition bigger.Several of the above quantitative analysis of the working group have carried out a ample number of tests, not to draw reliable conclusions.Temperature and humidity resistance properties. Multi-cellular struct ures exist diatom mud coating, in the course of ongoing moisture absorption, desorption cycles, while the close temperature changes will also affect the pore structure, and thus have an impact on the life of the coating. Objective setting temperature and humidity-resistant performance is to investigate the diatom mud products subject to temperature and relative humidity after many changes, which affect performance and service life.Functional technical requirements.Diatom mud decorative wall material diatoms as the main functional materials, and therefore has specific properties, such as good moisture absorption and put wet, formaldehyde adsorption properties. Because diatom mud decorative wall material having a strong adsorption, water vapor is a good carrier, bacterial and mold growth is moisture conditions. In order to avoid long-term use of the product in principal is easy to mildew, diatom mud wall material goods should be reduced by the addition of anti-bacterial mold mildew case material, so this performance standard in mold and mildew can be performed as a function durability index provisions.Diatom mud wall material has a good adsorption, not only on the ability of the adsorption of water vapor in the air, the smell in the air molecules has the same absorption features. This standard is currently selected in the home are more pertain about formaldehyde gas as a representative diatom mud adsorption capacity to detect harmful gas molecules.If only clean diatom mud after adsorption of formaldehyde molecules over time to knock over saturation adsorption, adsorption of formaldehyde molecules could be desorbed overflow again cause harm to human health. Therefore, diatom mud wall material as an environmental health product requires a certain degree of purification, purification by adding functional materials, etc. to achieve in this standard indicators added formaldehyde purifying effect durability requirements.Diatom mud decorative wall material used in wet environments due to the coating process a monumental number of pores of the adsorption of water vapor, so easy to produce mold. As an environmentally healthy building materials and mold is necessary to achieve targets. coatingDiatom mud decorative wall material can effectively improve indoor air quality, beneficial to human health, with the introduction of industry standards, consumer sense of products continues to increase, in order to regulate the market, it would also promote the healthy and swell Rapid development. Compared to the traditional method of indoor air purification, air purification and diatom mud decorative material combination, with no energy, no secondary pollution, permanent purification, etc. and it is extremely suitable for hotels, guesthouses and the elderly, children and pets family.References1.
