How to choose high-quality uPVC Profile and give full play to its performance?

The pros and cons of uPVC Profile directly affect everyone's engineering benefits. During welding, the weld fillet may be cracked due to improper welding process. The processing technology, especially the two processes of cutting and welding, must be strictly controlled to improve the strength of the weld fillet; The set temperature of the welding plate does not match the actual temperature. For example, the set temperature of the welding plate is 250 degrees and the actual temperature is only 245 degrees or 255 degrees. This phenomenon directly affects the welding quality; the solution is to check the process temperature and see the welding temperature Whether it is reasonable is mainly through visual inspection of 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.

uPVC Profile doors and windows should be painted with preservatives on the contact surface with cement mortar for anti-corrosion treatment. Plastic steel windows should be wrapped or pasted with plastic film before plastering. The plastic should not be damaged before the doors and windows are installed and the indoor and outdoor wet work is not completed. Film, to prevent the erosion of the surface layer of the mortar. The protective film of the plastic steel window should be torn off before handing over. It should be torn lightly, and a shovel should not be used to prevent the surface from being scratched and affecting the appearance. For jelly, wipe clean with cotton silk dipped in special solvent. If spot scratches are found, use a small brush to dip the dyeing solution for dyeing and patching. It is strictly forbidden to wipe or smash the plastic steel window frame during the erection and dismantling of shelves, outdoor plastering, steel keel installation, pipeline construction and transportation.

In the installation of doors and windows, the gap between the doors and windows and the junction between the glass and the profile must be glued and sealed. The quality of the sealant or glass glue will directly affect the later use of the glass glue. If the choice of glue is careless , There will be glass glue cracking. So in the choice of sealant, you can use acid glass glue, which is less prone to cracking.

If you choose a high-quality uPVC Profile and give full play to its performance, you must operate strictly according to the instructions. Only in this way can you achieve the desired effect. If you still don't understand during the operation, please contact us in time.
