New building energy-saving materials will become the inevitable trend of future development

China is in a new urbanization process, about 5 trillion a year in real estate investments as well as more than 25 million square meters of GFA completed . Future benefit from the national energy policy and market guidance, especially building energy efficiency standards gradually improved, new building materials, promote the use of energy , will be the inevitable trend of development stone coated metal roofing tile.
Among them, building exterior insulation system, for example , the existing organic insulation materials such as polystyrene board, phenolic board has been unable to meet the market needs, because of its flammable, combustible at this stage application has been limited. The traditional inorganic insulation materials such as mineral wool type , foam cement -like material , though not burn, but has a higher thermal conductivity can not be called the best insulation material. For exterior wall insulation technology is concerned , not only requires thermal insulation , energy conservation, low-carbon economy to meet the requirements , you must also ensure that the same safety and building life stone coated metal roofing tile.
As new materials and a variety of functional coatings research and production of Beijing New Technology Co. Benzema concerns the thermal resistance of the wall , more attention to insulation system security , durability and overall life improved. Development of independent innovation ultrafine SiO2 powders comprehensive insulation materials - ZM fireproof insulation board . The insulation material of inorganic fiber reinforced materials, and add the infrared opaque earth powder additives, modified mixing , pressing and drying and curing plate made ​​, massive and tubular insulation products. At 950-1025 ℃ under use, but also in the building to withstand a minimum temperature stone coated metal roofing tile.
Composite thermal insulation material powder is low , because the SiO2 which is a low thermal conductivity of the material itself , on the other hand , ultrafine SiO2 composite material , the thermally conductive particles and the cross-sectional area of ​​contact between the particles is extremely small, and thus heat conductivity naturally small. Convective heat from the gas is concerned, generally when the porous material temperature change is large, easy to cause gas convection, while ultrafine SiO2 composite materials because the pore tiny , difficult to produce gas flow . Gas molecules can cause thermal motion nor heat transfer , but void SiO2 composite particle diameter than the mean free path of gas molecules short and therefore there is no collision between gas molecules caused by the heat transfer process . Furthermore , the composite material is added to the infrared opaque additives. Therefore, the general insulation materials, the heat radiation effect can be cut off . SiO2 ultrafine particulate composite insulation materials with good insulation properties and heat resistance, is a promising use of thermal insulation materials stone coated metal roofing tile.
In the field of architectural coatings , in recent years there are also some play to reflect the sun's infrared light -based insulation coatings, which is now often said heat reflective paint or called reflective insulation coatings. With the increasingly urgent demand for energy efficiency in buildings , products can not meet a single white multi-colored exterior house paint requirements , while color reflective insulation coating because of the high absorption in the visible band and pigments poor weather , making promotion and application greatly restricted stone coated metal roofing tile.

There are babies in the family, home improvement consumer safety and environmental protection is a key consideration a big problem. This year in July , the citizens of Nanjing Liu had its own newly renovated house conducted air quality testing , the results show with a lot of " children's materials ," the children's room heaviest pollution , resulting in Sharon has not yet moved into a new home . Reporters in the building materials market found that many home improvement materials Pong on " Children " brand , price has also risen a lot, but really is suitable for children's room to use , many businesses will only use "green " word stall , without offering more number of test data stone coated metal roofing tile.
Development of children's products, home improvement materials have
In the market, no matter what the product , only the "child" is linked, will be able to sell at high prices . Now in the building materials market , raised " children " brand of home improvement materials are also frequent , where " children paint" is become the market selling products. In one owns " Children paint" paint store, a staff member said that many people in the children's room decoration wall using specially designated children's paint, high prices, but very popular in the market. But he also admitted to reporters , children paint just some of the more environmentally friendly paint , is such a gimmick stone coated metal roofing tile.
In the bathroom market , some brands have begun to build a child-specific sanitary products . Arrow, Faenza and other brands have dedicated children's toilet , recently Faenza is specifically designed for children, developed a series of products, including sinks, toilets, bathtubs , etc. But in fact, a smaller version of adult bath products , an increase of some children elements stone coated metal roofing tile.
In addition, there are many aspects of lighting products Children lights. The lighting in the Stone Forest Plaza, home sales floor , the reporter found that some elements of the brand launched a cartoon chandeliers, ceiling lamps , higher prices than ordinary lamps around 10-20% , but there is still a lot of people to ask . Just this month , a Disney Children Philips lighting products in Europe and the United States, Philips official said , the product is assembled and selected materials considered security reasons, you can ensure that children are safe to use stone coated metal roofing tile.
Children are environmentally safe materials to be verified
Reporters saw in the market , such as green paint , the paint has a lot of such features , according to purification of formaldehyde , benzene, purified , low TOVC other functions contained nowhere , price also 500-1000 per month. Insiders said , furniture, paint and toys painted specifically for children GB , there are strict requirements on hazardous substances , but the wall paint did not " Children paint " the specific standard, in fact, just the concept of speculation , consumers can not blindly stone coated metal roofing tile.
" Children's lighting is just used some cartoon elements that are truly environmentally friendly materials used , the light source is not known if it is safe in children is even more narrow version of bathroom sanitary products, unless the home space to set up a special children's toilet , the average consumer generally do not buy . " a decoration company responsible person said.
Decoration Industry Association experts said , many marked " children " brand of home improvement materials , that is to say through the more high-end , environmentally safe products . But not just on the waterfront " children card" is the environmentally friendly products , consumers must keep their eyes open when necessary, we may ask for the relevant test reports to see if the product safety and environmental protection stone coated metal roofing tile.
Industry experts also reminded owners renovated , decorated children's room the best looking finish third party company to do testing , environmental testing , and put some green plants in the room properly . After renovation must windows open for ventilation , at least three months before admission stone coated metal roofing tile.
