steel doors and windows

[qizhenapp]

<p>Plastic doors and windows of the main raw material is polyethylene resin, in the molding before the need to add titanium dioxide, UV absorbers, processing modifiers, impact modifiers, internal and external lubricants and fillers. As the basic structure of the profile is PVC resin, so there are some characteristics: processability in the molten state, the plastic has a relatively high mobility, so through the mold can form a precise cross-section structure, in order to achieve the window should have the function need. </p><p>And can form a split chamber to improve the window of the insulation, noise, drainage function, can avoid the enhanced steel corrosion. Sound insulation good steel and aluminum windows sound insulation performance of about 19 decibels, plastic windows of the sound insulation performance can reach 30 dB or more. In the increasingly noisy urban environment, the use of plastic windows can make the indoor environment more comfortable.</p><p> To achieve the same requirements to reduce noise, the installation of aluminum windows of the building and the distance between the traffic must be 50 meters, and the installation of plastic windows can reach 18 meters. </p><p>The effect is very good. As a result of economic development, urban noise problems are becoming more and more serious, and plastic windows for improving people living and working sound quality of the environment will provide a greater contribution. Another steel window corrosion-resistant, can be used in coastal, chemical plants and other corrosive environment, the average user can also reduce the use of maintenance paint and labor costs. Appearance and domestic decorative requirements to adapt to the requirements, and the human body feel more comfortable than the metal. As the steel doors and windows have some of the above advantages, in our country is a lot of applications, a new trend in the construction sector.</p>
