The surface of the UPVC Profile window should be smooth and flat, with no welding and cracking, the sealing strip should be flat without curling, no grooves, and the rubber strip should be odorless. When the UPVC window is closed, there is no gap between the fan and the frame. The four doors and windows are all connected together without screws. The sliding doors and windows should slide freely, with soft sound and no dust falling off. There are steel linings in the frame and fan of the UPVC window. The glass is installed flat and firm and does not directly contact the profile. If it is double-glazed, there should be no dust and water vapor in the interlayer, and all parts of the switch are tight and flexible. UPVC Profile windows must be professionally processed on the factory floor and cannot be made on site.
If there are greasy dirt and other difficult-to-handle things on UPVC Profile doors and windows, it is best not to use strong acid or strong alkali solution for cleaning, so that the smooth surface of the profile will be damaged, and it will also destroy the protective film and oxide layer on the surface of the hardware. Causes oxidative reactions to rust. If there are particles and other debris in the UPVC Profile door and window frame, it should be cleaned up immediately. Once it encounters rain and snow, it is easy to block the drainage channel and cause poor drainage or water leakage. When opening and closing doors and windows, pay attention to moderate strength, maintain good living habits, and avoid man-made blows or hard objects that cause damage or damage to people. Especially children and the elderly must pay attention to the ability to install guardrails outside.
The role of the steel lining embedded in the UPVC Profile is more important in the plastic-steel window. The steel lining is embedded in the plastic profiles of the four-sided frame of the window sash, which can enhance the compressive and tensile strength of the window and play a reinforcing role. The lining must be treated with anti-corrosion and anti-rust, and the thickness should not be less than one millimeter. How to identify whether plastic steel doors and windows are inlaid with steel lining, you can start from the following points. Use a magnet to check whether there is a steel lining inlaid in the plastic steel. Carefully observe the shape of the window frame and sash, whether there are automatic nails or rivet caps exposed outside, because the UPVC steel lining is to be fixed with the plastic profile, it must be fixed with automatic nails or rivets, so look at the window frame. Or whether there are nail caps on the outer wall of the window sash. It is also a method to check whether the steel lining is added to the plastic steel. You can feel whether the steel lining is added to the plastic steel window from the weight. If the weight of the UPVC window is relatively heavy, it is generally added. Steel lined.
UPVC Profile continuously promotes quality improvement and brand cultivation, pays attention to scientific research and development, and has won many mechanical industry science and technology awards. The research and development and application of these achievements have promoted the technological progress of the UPVC Profile industry and the improvement of the overall level.
