The quality of UPVC Profile directly affects our engineering benefits. During welding, the welding angle may be cracked due to improper welding process. The processing technology should be strictly controlled, especially the two processes of cutting and welding, in order to improve the welding angle strength; 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 the visual inspection of the weld flash after welding. After welding, the weld bead should be yellowish. When adjusting, 5 degrees is a gradient to adjust slowly until the yellowish phenomenon occurs.
If the window sill in the home is relatively wide, a layer of UPVC Profile plastic steel window can be installed on the inside or outside of the original window. UPVC windows should be well sealed, and the cavity distance between the two layers of windows should preferably be more than 10 cm. UPVC doors and windows are generally sealed with rubber strips. Unlike ordinary aluminum alloy windows, which are "hard-to-head", the sound insulation effect is more obvious; while casement windows have better sealing properties than 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 due to the lead sulfide produced by the reaction between sulfur and lead in the inferior rubber strip. In this case, the assembly plant should be advised to replace the high-quality rubber strip in time. Then there are reasonable windows. Reasonably designed window type, the glass size should not be too large. The cavity material of the combined window should be fixed up and down. The water-facing surface of doors and windows 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 accessories are not matched, the purchased steel lining is not suitable, too large or too small, pay attention to the different uses of the wind block, bumper and anti-theft block, pay attention to the eccentric lock center of the door lock, aluminum slide rail and semi-circle lock 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. Before plastering, plastic steel windows should be wrapped or pasted with plastic film for protection. Before the doors and windows are installed and the indoor and outdoor wet work is not completed, the plastic cannot be damaged. film to prevent the mortar from eroding its surface. The protective film of the plastic-steel window should be torn off before delivery. It should be torn off lightly, and a shovel should not be used to prevent the surface from being scratched and affecting the appearance. For example, the surface of the plastic-steel window has When using a glue-like substance, it should be wiped clean with cotton silk dipped in special solvent. If local scratches are found, use a small brush dipped in dyeing solution to dye and repair. During the erection and dismantling of shelves, outdoor plastering, steel keel installation, pipeline construction and transportation, it is strictly forbidden to wipe or smash the plastic steel window frame.
In the installation of doors and windows, the gaps between doors and windows and the junction of glass and profiles must be glued and sealed. The quality of sealant or glass glue will directly affect the later use of glass glue. If the glue is not selected carefully , the glass glue will crack. Therefore, in the choice of sealant, acid glass glue can be used, which is less prone to cracking.
To choose a high-quality UPVC Profile and give full play to its performance, you must operate it strictly according to the instructions. Only in this way can you achieve the desired effect. If you have any questions about the operation, you are welcome to consult us in time.
