Do you have a plastic door?
Sound insulation good steel and aluminum windows of the 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. According to the information provided by Japan, to achieve the same requirements to reduce noise, the installation of aluminum windows and traffic roads must be 50 meters away from the distance, and the installation of plastic windows can reach 18 meters. According to the OKorder Institute of Labor Protection, the use of plastic windows of indoor noise dropped to 32DB (A), 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 environment quality 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.
Energy-saving plastic doors and windows than other doors and windows in energy saving and improve the indoor thermal environment, there are more superior technical characteristics. According to the Institute of physical testing, single glass, aluminum window heat transfer coefficient of 64W / M2K; single glass steel window heat transfer coefficient is 47W / M2K or so; ordinary double glass of steel, aluminum window heat transfer coefficient Is 3.7W / M2K or so; and double glass plastic steel window heat transfer coefficient of about 2.5W / M2K. Doors and windows accounted for 30% of the construction area of the outer envelope, the heat accounted for 49%, which shows that plastic windows have a very good energy efficiency.
Plastic steel 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:
1. Machinability 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 functional needs. And can form a split chamber to improve the window of the insulation, noise, drainage function, can avoid the enhanced steel corrosion.
