What kind of paint decoration wall best ah! Environmental protection point.
To prevent VOC damage, mainly from the source to start, to prevent non-environmentally friendly building materials; Second, often ventilated, and even heating baking, so that VOC release faster; third, if necessary, installed activated carbon air purifier; After the best test to confirm the VOC does not exceed the standard, and ventilation after a month to stay; fifth, placed some can absorb harmful substances such as flowers, such as Chlorophytum, aloe vera, horsetail, ivy and aspartum. In addition, in the living room or courtyard can be placed rose, cuckoo, tulips, lilies and orangutans, etc., they can absorb a lot of VOC, but they should not be placed in the bedroom, because they have other negative factors.
TVOC is one of the three most important pollutants in the air (PAHs, volatile organic compounds and aldehydes). VOC is the organic vapor with a saturated vapor pressure of more than 133.32pa at room temperature. Its boiling point is 50 ℃ to 250 ℃, which can be evaporated in the air at room temperature. Its toxicity, irritation, carcinogenicity and special odor Sex, will affect the skin and mucous membranes, causing acute damage to the human body. Main Ingredients The main components of VOC are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene, organic chloride, freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum Hydrocarbon compounds and the like. The main source of VOC: outdoors, mainly from fuel combustion and transportation; and in the interior are mainly from coal and natural gas and other combustion products, smoking, heating and cooking smoke, construction and decoration materials, furniture, household appliances, cleaning Agents and the body itself emissions and so on. In the interior decoration process, VOC mainly from paint, paint and adhesives. General paint VOC content in the 0.4 to 1.0mg? M3. Due to VOC with strong volatility, under normal circumstances, the paint after 10 hours of construction, can be volatile 90%
I used Dulux, also used Nippon Paint, the feeling is still very good. In fact, the home decoration to see whether the paint is environmentally friendly to see VOC, VOC refers to 1 liter of paint contains organic volatile weight, and TVOC refers to 1 liter of paint to remove water substances which contain organic volatile weight, the current majority The wall solids content of the interior wall coating is about 35% -40%, when the TVOC limit of 100g / L, the corresponding VOC is about (39-44) g / L. Therefore; ring standard TVOC limited standard is far more stringent than the national standard VOC standard. In fact, even 100% of the solid, VOC is still greater than the TVOC. Thus, it is seen that the TVOC in the control recipe is more direct than controlling the VOC.
General decoration materials are formaldehyde, formaldehyde volatilization is a slow process, long can reach 10 years, so that often the window ventilation, so that the room as soon as possible to disperse formaldehyde, there can be some other methods, you can In the room to raise some plants, such as cactus, Chlorophytum, horseradish, ivy, iron tree, chrysanthemum, etc., in addition to formaldehyde have little effect, so only play a small role. So to tie in with other materials, you can use some Maya blue, activated carbon, etc. in addition to formaldehyde, but the adsorption of activated carbon will be less saturated effect, as well as photocatalyst wood oil can be painted in the wooden furniture or floor, the formaldehyde decomposition.
