transparent material surface

Condensation phenomenon is common in daily life, especially the condensation of transparent material surface, to people's production and life has brought great inconvenience. Glass, agricultural film is the most common and most commonly used transparent material, when such a transparent material on both sides of a certain temperature difference, the low temperature of the [url=http://usastarker.com/deck-price/840.html]house design plans with 90sq floor area[/url] surface moisture saturation vapor pressure is lower than the surrounding environment of vapor pressure, the water vapor to the surface of the object , And with a small water droplets precipitation, the formation of dew or fog, tiny dew on the light to form diffuse reflection, significantly reducing the light transmittance of the glass, thus affecting the line of sight. So that the surface of the object hydrophilic: to reduce the surface of the object on the water contact angle, so that the small droplets on the surface of the small droplets do not form a small drop of water, but in the surface [url=http://usastarker.com/deck-price/839.html]wpc panels anchor system[/url] spread and thin film, reducing the diffuse reflection of light, thus ensuring the Transparency of the material. The hydrophilization of the surface of the object is achieved primarily by coating a variety of surfactants, by mixing the surfactant with a resin, a hydrophilic polymer or forming a phosphate hydrophilic layer. So that the surface of the object hydrophobic: to improve the surface [url=http://usastarker.com/deck-price/838.html]cheapest wood plastic composite decking market[/url] of the object between the contact angle with the water, so that water droplets fall under the action of gravity. This method is mainly in the surface of the object coated with organosilane or fluorine coating. So that the surface temperature of the object is higher than the dew point: there are already in the car windshield to increase the heating device to achieve anti-fog patent reports. But the method costly, easy to damage, maintenance more difficult. So the method is applied less. As China's population, anti-condensation products market is huge, the development of transparent materials on the surface of anti-fog and its application products, with practical significance. In this study, polyacrylamide transparent anti-condensation garden archway trellis use composite coatings were prepared by solution copolymerization with methacrylic acid (MA), β-hydroxyethyl methacrylate (HEMA) and acrylamide (AM) as comonomer to solve the problem Product condensation problems.
