Plastic-steel doors and windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., are extruded into the material, and then cut, welded or screwed Made into door and window frame fans.
Equipped with sealing strips, tops, hardware, etc., and at the same time to enhance the rigidity of the profile, steel lining (reinforcing ribs) needs to be filled in the cavity of the profile that exceeds a certain length. The portal windows made in this way are called plastic steel doors and windows.
Performance
1. Heat preservation and energy saving
Plastic-steel doors and windows have a multi-cavity structure with good heat insulation performance. Its heat transfer performance is very small, only 1/357 of steel and 1/250 of aluminum. It can be seen that plastic doors and windows have significant heat insulation and heat preservation effects, especially for heating Modern buildings with air-conditioning equipment are more suitable.
2. Physical properties
The physical properties of plastic steel doors and windows mainly refer to: air permeability (air tightness), rainwater leakage (water tightness), wind pressure resistance, heat preservation and sound insulation properties of PVC plastic steel doors and windows. Because the plastic-steel door and window profiles have a unique multi-chamber structure and are welded to form doors and windows, all gaps in the installation of plastic-steel doors and windows are equipped with door and window sealing strips and tops, so they have good physical properties.
3. Corrosion resistance
Plastic-steel doors and windows have good corrosion resistance due to their unique formula. Secondly, the corrosion resistance of plastic-steel windows depends on the use of hardware. Under normal circumstances, hardware is metal products, but in industries with corrosive environments, such as food, For medicine, health, chemical industry and coastal areas, rainy and humid areas, use anti-corrosion hardware (engineering plastics), which has a service life of 10 times that of plastic steel doors and windows.
4. Weather resistance
Plastic-steel doors and windows adopt a special formula, and the raw materials are added with ultraviolet absorbers and low-temperature impact resistant agents, thereby improving the weather resistance of plastic-steel doors and windows. Long-term use in the temperature and climate environment, between 30 degrees and 70 degrees, in the changes of scorching sun, heavy rain, dryness, and humidity, there is no discoloration, deterioration, aging, embrittlement, etc. Plastic-steel windows have been used in Western Europe for 30 years, and their materials are as good as ever.
5. Fire resistance
Plastic steel doors and windows are not spontaneously combustible, non-combustible, self-extinguishing away from the fire, safe and reliable, and meet the fire protection requirements. This performance has expanded the use of plastic steel doors and windows.
6. Insulation performance
Plastic steel doors and windows use excellent electrical insulators with special profiles, which are non-conductive and have a high safety factor.
7. Air tightness
Plastic-steel doors and windows are fine and smooth, and the quality is consistent inside and outside. After special surface treatment, easy processing, cutting and welding, the length, width and diagonal of the finished door and window can be within plus or minus 2MM, and the processing accuracy and angular strength can be Up to 3000N or more.
8. Sound insulation performance
The main reason lies in the sound insulation effect of the glass which accounts for about 80% of the area. Some sound insulation plastic steel doors and windows products on the market adopt different glass combinations based on the resonance transmission principle of sound waves and the cooperation of lotus roots, such as hollow glass plastic steel windows, ordinary double-layer glass, Enhance the sound insulation effect of doors and windows. In terms of door and window structure, the use of high-quality rubber strips and plastic sealing accessories makes the sealing performance of plastic-steel doors and windows significant
