What is the difference between plastic doors and windows and steel doors and windows?
PVC plastic doors and windows in the country is widely known as the steel doors and windows, plastic doors and windows is based on polyvinyl chloride (PVC) resin as the main raw material, with a certain percentage of stabilizers, colorants, fillers, impact modifier, Absorbent (shielding agent) and other additives, the extrusion of the material.
Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.
According to the characteristics of profiles, the profiles are roughly divided into European and American two.
European doors and windows of its characteristics are: profile formulations still use the traditional lead salt heat stabilizer, a small number of countries and enterprises began to use environmentally friendly organic tin heat stabilizer; main section of the profile profile is generally designed for three or four main chamber, The total number of chambers to 6 to 8, wall thickness is generally 2.5 ~ 3.0mm.
Doors and windows with fan-fan frame structure, fan section larger, with pulley, can be removed; built-in glass, dry mosaic; window open in the foreign under the hanging window-based, a small amount of sliding window.
American doors and windows: the main formula for the use of environmentally friendly organic tin heat stabilizer, to avoid the production, processing, use of lead salt toxicity of the drawbacks; development for the multi-cavity section, the second is to reduce the profile wall thickness, 1.80mm; while increasing the number of internal reinforced steel and the chamber, the chamber generally have 9 to 13. In addition to reducing the strength of profiles, but also improve the thermal insulation and sound insulation effect.
The sliding window for the frame package fan, improved the sealing and safety performance, cancel the fan pulley, reduce the fan section at the same time, the window lighting performance has been improved. Developed a standard installation method for pulling windows and new mounting wings.
