In the blink of an eye, the New Year is coming, and it is another winter. Generally speaking, after entering the winter, the door and window industry will also usher in the off-season. After all, the residents do not want to be decorated with cold, but some special circumstances are not ruled out.
The low temperature environment will have a great impact on the steel profile. If the processing method under normal temperature environment will have a serious impact on the processing quality of plastic steel doors and windows, it is necessary to pay attention to the following points to prevent it.
1. Before cutting and welding, the profile should be stored in an environment above 5 °C for 24 hours.
2. The welding process temperature and time are appropriately improved on the basis of the original welding process.
3. The length of the bead is suitable, and should not be too long. Do not excessively pursue the "strict seam". If the bead is too long, the welding angle will be cracked or the bead will be grooved.
4. Use high quality sealing strips that are still soft under low temperature conditions. Inferior rubber strips will harden at low temperatures and completely lose their elasticity, which has a great influence on glass assembly.
5. The length of the aluminum slide rail is strictly prohibited. The length of the aluminum slide rail should be shorter than the inner mouth size by about 2mm, leaving a margin on both sides.
6. The installation of the wall on the door and window, especially the assembly of the glass bead, should be carried out in an environment above 5 °C. When assembling the glass bead, if the ambient temperature is low, it is recommended to make an incubator, and the glass bead is wrapped with an electric blanket for a period of time before being assembled.
7. When assembling the glass bead, if there is any jam, check the size and specifications and check the welding slag cleaning and the quality of the strip. Do not knock it in place, causing damage to the welding angle or glass.
