uPVC Profile is widely used, so after a period of use, how can the plastic steel profile become white and bright?
Doors and windows are common in uPVC Profile. Plastic-steel windows are a form of windows that are actively promoted by the state after wood, iron, and aluminum alloy windows. This is mainly due to its low price and good performance.
uPVC Profile is based on polyvinyl chloride resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, fluorescent brighteners, ultraviolet absorbers, etc., through extrusion molding. Everyone knows that most of our common door and window borders are white, mainly because the white makes the room bright and beautiful. We often encounter such a problem, that is, after a period of ultraviolet radiation, the profile will appear yellow. The reason is that there is no special fluorescent whitening agent for plastic steel profiles.
The reason why uPVC Profile can be widely used and gradually replaced wooden and aluminum doors and windows is inseparable from its unique advantages. Compared with aluminum and wooden doors and windows, the price of plastic steel doors and windows is lower, and the price of plastic is much lower than that of Aluminum with the same strength and life; durable, reinforced section steel is added to the profile cavity, which greatly improves the strength of the profile, has the effects of earthquake resistance and wind erosion resistance; good thermal insulation performance, the same type of room uses plastic steel doors and windows in the summer The temperature is 5-7℃ lower than the room with aluminum doors and windows on average, and 8-15℃ higher in different areas in winter; the sound insulation performance is good, the plastic steel doors and windows are assembled by welding technology, and the closed multi-cavity structure can shield the noise The effect is very obvious.
