Can be used to verify the authenticity of the reflective heat insulating coatings

Will reflect heat insulation coatings products introduced before the European and American companies are vacuum micro beads as filler, with low thermal conductivity as heat insulation means to produce heat insulation coating products, this is a low reflectivity of the ordinary white wall paint, he advertised as the coating layer is very small, can block the conduction of heat, then they will not mention the solar reflectance, so they also claim that their products can use. In fact, the heat insulation paint really do?

As we all know, a large number of traditional thermal insulation materials used in the use of more than 1 cm thick and above can effectively block the heat transfer, these ordinary thermal insulation material thermal conductivity is much less than the thermal conductivity of vacuum micro beads. However, the vacuum coating of the coating thickness of the coating has been very impressive, so a millimeter thick coating heat can be transmitted through a moment of transmission, it can be said that the effect of the heat insulation coating is very poor, purely symbolic, no real energy saving effect.

Will reflect heat insulation coating of the solar reflectance of 92%, is the world's most reflective reflective insulation coatings. Will is China's first national test and launch of the product service to the community of manufacturers. Will reflect heat insulation coating is clear to reflect as the main means to cool energy-saving products. Ten years, weiershun reflective thermal insulating coatings have occupied more than 90% of the building insulation market, forcing many before the name of high-tech products in Europe and America the vacuum micro bead heat insulation coatings have reversed course, swallow small coefficient of thermal conductivity of magic, the banner of high reflectivity, false map deceive consumers.

The solar reflectance is an important index of reflecting heat insulating coatings, but the general users can not detect the results. How to distinguish true and false reflective heat insulating paint it? Some so-called reflective paint products, the company, in the online "guide" with electric lights or water as heat source to verify the reflection of its products, which is very funny. Reflective coating reflection of the heat of the sun is the sun contains heat wave, and the lamp, water heat source is not completely the same, refrain consumers deceived.

Verification method for the authenticity of the heat insulating paint

A, heat insulation effect detection

1. first wash with water of 2 square meters of cement floor, according to the construction requirements of insulation coating paint on sunscreen.

2. ten days later, select the sunny weather, let the fierce sun exposure for 3 hours, with the central position of the contact type digital thermometer to test the coating, the surface temperature and the outdoor air temperature remained the same, that is to say coating is almost no absorption of heat from the sun. Fake sunscreen, due to the absorption of solar heat, coating temperature will be higher than the air temperature of 10 degrees above.

Identification of B and adhesion

1. the product is ten days after days of water washing and immersion coating for 30 minutes, with a tooth brush hard scrub, quality of the sun and heat insulation paint will not appear wear, poor quality products are washed, a rub will appear to fall off.

2.look at the project case, the election has been completed more than three years of practical observation in a sunny day, the sun has no heat insulation effect and most of the loss.

C, the difference between ordinary white exterior wall paint

The ordinary white outer wall coating, which has good hiding power, is coated with cement floor, in the first five days, the solar reflectance can reach 80%, and has certain heat insulation effect. But in under the action of solar radiation, ten days after the reflectivity will be decreased significantly. After half a year will fall to 40% below, and the reflectivity of the cement ground is almost the same. This is almost all of the fake sun protection sunscreen is no license without a license of the underground factory production, packaging barrels do not specify the place of production, or do not exist in the production of manufacturers.

2008 Foshan Shunde District Lecong Changfeng Furniture Co., Ltd., 2000 square meters of workshop painted with ordinary white exterior paint posing as sun screen and heat insulation paint and a week later found effect gradually lost, later the friend guides that my factory production real sun screen and heat insulation paint, procurement of 2 tons of Dowell Shun sun screen and heat insulation paint, brushing the 6000 square meters workshop (to apply the common exterior wall coating of 2000 square meters workshop and re brushing the again), in June this year also purchased 2 tons of Dowell Shun sun screen and heat insulation paint, brushing the 6000 square meters workshop.

In August this year, an industrial (Zhongshan) Co., Ltd. (Zhongshan white stone undershoot Industrial Park) is also used a known as (the website propaganda) has thousands of square meters of workshops (actually no plant, only a staff of a small company) three products. More than 15000 square meters workshop, painted a 1700 square meters found coating began serious discoloration, find me to plant, by our factory completed the remaining thirteen thousand square meters of factory building, the coating. Has been coated with the poor quality of the paint shop not only can not be separated from the heat, but also led to the tin surface is very difficult to deal with, has not yet found a good solution. That's because some people don't know about the sun's heat insulation paint, that the other paint factory can produce, the product quality is almost the same.

The following is the use of fake and inferior reflective heat insulation paint, but also forced to use the reflective insulation coating products will be the case of heavy coating:

Beijing, Shanghai, Wuhan, Guangzhou and other cities have a lot on their website posing as the production of insulation coatings manufacturers, in fact, just one or two people shell small companies listed on the Internet a lot of variety of products, take each a wide variety of tactics to deceive customers, theft I plant products for the construction have case on its website and promotional materials, even as long as there is customer calls consultation, to register on the Internet that are its customers, giving customers a lot of sense. Here to remind our customers in the use of sunscreen insulation paint, to learn more about the manufacturer's Case, understand the coating area and the project name is true, whether the address indicated on the production plants but also the product packaging, manufacturing plant Phone factories Are there really Trade and Industry Bureau registration, inspection report is true.
