First, the welding angle cracking analysis:
1, welding process problems 2, profile problems 3, impact by external forces 4, layering material is too long 5, internal stress cracking 6, the installation of low ambient temperature
Solution:
1. Strict control of welding process 2. Replacement of profiles 3. Finished products should be handled with care, avoiding excessive knocking force 4. The bead assembly should not be too long 5. Before cryogenic storage of profiles, welding should be performed in an environment not lower than 150C. Place it for 24 hours to avoid internal stress caused by sudden heating of low-temperature profiles. 6. The ambient temperature during installation should not be lower than 100C.
Second, the door window frame, the deformation analysis of the defect:
1, the product placed uneven ground 2, the form is not installed on the 3rd, the use of glass mats or improper use 4, profile chamber interior steel lining cross-section structure is not playing a due reinforcement role 5, the fastener spacing Large, steel linings and profiles are not connected.
Solution: 1. There should be no unevenness on the floor of the product. 2. The vertical balance should be ensured for the installation of doors and windows. The spacing between the connectors is not more than 600mm. 3. The installed glass spacers should be able to transfer the weight of the glass to the wall. The load-bearing weight of the door and window components 4, the gap between the assembled steel liner and the profile chamber shall not exceed 0.6MM, and if the gap is too large, it shall have a reinforcing effect. 5. The distance between the fasteners should not exceed 300mm, and the fasteners should not There is a slip phenomenon.
Third, the pressure plate cutting angle difference analysis:
1ã€Bad stencil is not adjusted or not matched 2.Compression squeezer is not pressed tightly
Solution:
1, adjust or replace the template 2, without affecting the cutting situation, try to adjust the pressure clamp to the nearest point of the cutting point, and ensure that the pressure clamp pressure material.
IV. Causes of yellowing of the contact area between the profile and the strip: The strip is not qualified, and the strip volatiles react with the profile
Solution: Replace the strip and strengthen the material inspection
Fifth, window fan falling angle causes analysis:
1. Frame fan welding diagonal line is large 2. The bottom of the window frame installation is not horizontal 3. The window fan is not equipped with glass pad or the installation is not standardized, the window weight is deformed by the weight of the glass 4. Hardware installation is not standardized
Solution: 1. Strengthen process product inspections. Substandard products are prohibited from using the next process. 2. Before the window frame is installed and fixed, the bottom of the window frame is leveled and measured with a horizontal tube. 3. Correct use of the glass pad to make the glass weigh. Pass through the function of the block to the hinge part, the hinge installation should be straight, under normal circumstances, the sash connection of the sash assembly should be uniform on all four sides.
Six, hollow glass sandwich water vapor causes analysis:
1ã€The quality of insulating glass sealant is poor, the sealant has a good trachoma breathability, the desiccant moisture adsorption is low 3, the insulating glass processing environment is humid
Solution: 1, use good quality sealant, use double seal to strengthen the process of self-test, strictly prohibited from cutting corners. 2. Avoid desiccant failure due to moisture 3. The processing environment is kept dry.
