A coating really clean taste and paint is environmentally friendly, mainly to see VOC.

The concept of clean-smell paint originated in Japan and refers to a special-effect functional coating that purifys odors and toxicity in the air, and the coating itself is almost non-toxic. But in China the concept is seriously confused. Many paint manufacturers have introduced a clean taste wall paint (latex paint), in fact, this coating simply can not "clean taste" function

. They are just latex paints that smell relatively small. However, China does not have the relevant standards and requirements for "clean taste" coatings. So large and small manufacturers have launched their own "clean taste paint."
how to judge the true clean taste
although the concept of clean taste is used by many manufacturers. But as long as you know the fundamental principle of clean taste paint can easily determine whether it is really clean taste paint: the real clean taste paint should be accurately called: special effects purifying air paint. Because the purification of air coating technology is mainly: phototalytic technology, so also known as "optical media special effects purification air coating" other technologies are not yet mature. And phototalytic special effects to purify air coating technology is only in the hands of the Japanese. So you only need to look at the product description of whether the effective purification of the air principle of the technical instructions can be seen.
is phototalytic action?
E. As chlorocerin converts CO2 into oxygen and other organic matter through photodetease, special titanium dioxide (Ti O2) absorbs ultraviolet light from the sun and fluorescent lamps and converts the oxygen and water molecules around it into a highly active active oxygen layer, which in turn breaks down the surrounding organic matter (formaldehyde, acetaldehyde, ammonia, bacteria, etc.) into water and CO2. This effect is called phototalytic action.
the function of optical
. 1. Purifying the air
can break down harmful elements such as formaldehyde into water and carbon dioxide and other stability elements, play the role of purifying the air.
HCHO (formaldehyde) - HCOOH (phototaplication) - (chemical adsorption) - H2O - C O2
. 2. Antibacterial, sterilizing, anti-mold
has a strong redox capacity, can effectively kill the surrounding bacteria (E. coli, Staphylococcus acobacterium, Penicillin staphylococcus, mold and other microorganisms), play an antibacterial role.
3. Deodorization
can break down the odor elements adsorbed in the surrounding acetaldehyde, acetic acid, ammonia and other odors, play a role in eliminating residual odors in the air.
C H3CHO (Acetaldehyde) - C H3CHOOH (phototalytic action) - (chemical adsorption) - H2O - C O2
. C H3CHOOH (acetic acid) - M-OH (deodorant) - M-OOCC H3 - H2O (chemical adsorption) - C O2 - H2O
N H3 (ammonia) - M -OH (deodorant) - M- ON H4 (Chemical Adsorption) - N O3-H2O (Photocatalyst)
4. Anti-fouling, self-purification
oily dirt in the air is adsorbed on its surface and is broken down into water and other stable gases, playing a role in anti-fouling, self-purification.
. Environmental protection, non-polluting
of reactive oxygen on the human body without any adverse effects, is non-polluting environmental protection products.
the validity of the phototalytic media
as long as the titanium dioxide crystals are well preserved and can receive a certain amount of ultraviolet light, it can permanently play the role of phototalytic media.the discovery of
photocatalysts and the use of titanium
dioxide were discovered in the 1970s by Professor Hiroshi Fujishima of the University of Tokyo in Japan, but the initial use of this effect on products was in the late 1990s and is less than 10 years old. However, its special environmental protection role has attracted the world's attention, and is widely used in self-cleaning tiles, glass, clean air coatings, new building materials and other fields. This technology was discovered by Japan and gradually extended to the world, Japan has always been in the world's leading position.
Japan Asa japanese coatings in 1998 produced the world's first phototastic products special effects purification air coating
this product is based on Japan's latest technology refined and produced titanium dioxide as raw materials, the further use of new technology to improve the effect of phototalytic media products, is to make the various effects of phototalytic media to effectively give full play to the typical phototalytic coatings. It was launched into the Japanese market in late 1998 and immediately caused a strong reaction, winning the Osaka Mayor's Award in April 1999.
although clean taste coatings are currently popular products, but most consumers do not fully understand the various coatings "clean taste" principle. The asymmetry of information leads to consumers in the purchase of clean taste paint in the weak side, individual manufacturers also take this opportunity to "net taste" concept confused. In general, there are two main "clean taste" principles on the market:
cleast coating principle
the first technology, that is, emulsion technology directly eliminate odor, that is, the real clean taste technology. Based on the net taste coating series developed by this platform, the coating itself has almost no odor, or the odor is ultra-low and can be distributed quickly, because of the complexity of the process, high cost, so only a few high-end brands can produce this coating. The use of this technology of products are mostly located in high-grade, medium-high-end, the price is relatively high. Only products that use this technology are truly clean paints. In addition to the finish, the matching net taste primer has also been put on the market, to help consumers better achieve a comprehensive clean taste painting.
The second technique, that is, the smell of emulsion covered with flavor, as the name suggests, only with the smell of fragrance to mask the pungent taste of the paint itself, so it is a "pseudo-clean taste" technology, not even called a technology, but an illusion. Although the fragrance can mask the pungent smell of the paint, does not mean that the odor is eliminated, so the user in addition to smelling the fragrance, unknowingly also by the paint odor damage. This technology is generally used in low- and medium-grade products, mainly in the paint aromatic smell and low prices to compete for the market, but there are also a few well-known brands to produce such "pseudo-clean taste" paint. Experts remind the vast number of consumers to pay attention to careful screening, the purchase of clean taste paint must choose well-known brands, at the same time before buying must personally smell.
a paint really clean taste and paint is environmentally friendly, mainly to see voC
. VOC refers to 1 liter of paint contains the weight of organic volatiles, and TVOC refers to 1 liter of paint to remove water in the substance containing the weight of machine volatiles, most of the inner wall coating volume solid content of about 35%-40%, when the TVOC limit of 100g/L, the corresponding VOC is about (39-44) g/L. Therefore, the limit standard of TVOC in the ring label is much stricter than the limit standard of VOC in the national standard. In fact, even if 100% solid, VOC is still larger than TVOC. Thus, the TVOC in the control formula is more direct than the control VOC.
TVOC is one of the three organic pollutants (polycyclic aromatic hydrocarbons, volatile organic compounds and aldehyde compounds) in the air. VOC refers to saturation vapor pressure above 133. 32pa organic matter, its boiling point in 50 degrees C to 250 degrees C, at room temperature can be evaporated form in the air, its toxicity, irritation, carcinogenicity and special odor, will affect the skin and mucous membranes, causing acute damage to the human body. The main components of VOC are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene, organochloride, fluorine series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compounds.
VOC's main sources, outdoors, come mainly from fuel combustion and transportation, while indoors they come mainly from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, building and decorative materials, furniture, household appliances, cleaners and emissions from the human body itself. VoC comes mainly from paints, coatings and adhesives during interior decoration. The VOC content in general paint is 0. 4 to 1. 0mg/m3. Because VOC has strong volatility, in general, within 10 hours after paint construction, can wave 90%, and the solvent VOC in the paint air-drying process only releases the total amount
This depends largely on requirements and conditions. The technical equipment conditions for detecting TVOC are high, usually using gas chromatography, but also using Fourier transform infrared spectroscopy, fluorescence spectroscopy, ion chromatography and reflection interference spectroscopy.
room VOC concentration is 0. 16mg/m3 to 0. 3mg/m3, basically harmless to human health, but often in the decoration more than, especially improper decoration.
To prevent VOC injury, mainly from the source, to eliminate non-environmentally friendly building materials, secondly, often ventilation, and even heating baking, so that VOC release accelerated; In addition, monthly seasons, azaleas, tulips, lilies and orangutan trees can be placed in the living room or courtyard, which absorb large amounts of VOCs, but they should not be placed in the bedroom because they have other negative factors.
