uPVC Profile has gradually been widely used. The surface of the plastic-steel profile window should be smooth and flat, without welding fracture, the sealing strip should be flat, without curling, no grooving, and the rubber strip has no odor. It is well received by the majority of users. As the types of products on the market continue to increase, it is more difficult for the majority of users to choose high-quality plastic steel profiles, so we need to explain in detail how to choose high-quality plastic steel profiles.
The key points and precautions of each welding process of uPVC Profile have been explained in detail in the profile manual, but why users still have fillet cracking caused by improper welding process when welding, and the processing technology must be strictly controlled, especially cutting and welding. A process to improve the strength of the welding angle; the set temperature of the welded plate does not match the actual temperature, for example, the set temperature of the welded plate is 250 degrees but the actual temperature is only 245 degrees or 255 degrees. This phenomenon directly affects the welding quality; The method is to check the process temperature to see if the welding temperature is reasonable, mainly by visually inspecting the weld bumps after welding. After welding, the weld bead should be slightly yellow. When adjusting, 5 degrees is a gradient and slowly adjust until the yellowish phenomenon appears.
If the window sills in your home are relatively wide, you can add a layer of plastic-steel profiles to the inside or outside of the original windows. Plastic-steel windows should have good airtightness, and the cavity distance between two layers of windows is best to be more than 10 cm. Plastic steel doors and windows are generally sealed with rubber strips, which are different from the "hard-to-hard" of ordinary aluminum alloy windows, and the sound insulation effect is more obvious; while the airtightness of casement windows is better than that of sliding windows. This method is suitable for situations where outdoor traffic noise is not particularly serious, and the cost is relatively low.
The obvious yellow line at the contact between the profile and the rubber strip is mainly caused by the lead sulfide produced by the reaction of sulfur and lead in the inferior rubber strip. In this case, the assembly factory should be advised to replace the high-quality rubber strip in time. Then there is a reasonable window design. The window type is reasonably designed, and the glass size cannot be too large. The cavities of the combined window should be fixed up and down. Doors and windows facing the water surface should not be too large, and the drainage holes should not be too small. The overlap of sliding windows should not be less than 8mm. The window fittings are not matched. The steel lining purchased is inappropriate, too large or too small. Pay attention to the different uses of the wind block, bumper and anti-theft block. Note that the lock center of the door lock is eccentric. Aluminum slide rails and semi-circular locks are divided into different types , The appropriate model should be selected.
