Metal Doors The main reason for the difficulty of push and pull
Aluminum doors and windows maintenance coup
1, aluminum doors and windows in use, the action should be light, push pull its natural; found difficult not hard pull hard push, should first rule out the fault. Fouling, deformation is the main reason for the difficulty of push and pull of aluminum doors and windows, to keep the door frame clean, especially the sliding slot cleaning. Vacuum cleaner can be used to suck the tank and the door closed the fouling.
2, clean aluminum doors and windows, people do not step on the aluminum frame, do not pull the box for support.
3, aluminum doors and windows can be used soft cloth stained with water or neutral detergent, do not use ordinary soap and detergent, but can not use decontamination powder, toilet and other strong acid cleaning agent.
4, after the rain, should be wiped in time wet glass and window frames, with particular attention to wipe dry chute water. Chute with a long time, increased friction, can add a little oil or coated with a layer of wax oil.
5, should always check the aluminum alloy frame connection parts, tighten the bolts in time, replace the damaged parts. Positioning pin, wind support, to spring and other aluminum doors and windows of the vulnerable parts, to always check, regularly add lubricants to keep clean and flexible.
6, sealed tops and glass plastic seal is to ensure that the door and window sealing the key structure of insulation, if the fall to timely repair, replacement.
7, often check the aluminum alloy wall joints, the course of time if loose so that the overall deformation of the framework, so that doors and windows can not be closed, sealed. So the connection of the screw loosening should be immediately tightened, such as screw feet loose, the application of epoxy strong glue to adjust a small amount of cement seal.
Here we introduce you to install the need to know some of the little knowledge.
First, the purchase notes
⒈ thickness: aluminum alloy sliding doors have 70 series, 90 series of two, residential interior aluminum alloy sliding door with 70 series can be. The aluminum alloy sliding window used as a closed balcony shall be not less than 70 series.
⒉ strength: tensile strength should be up to 157 Newton per square meter, yield strength to reach 108 Newton per square millimeter. When buying, you can use the hand to bend the profile, let go after the recovery.
⒊ color: the same aluminum alloy color should be consistent, such as color is obvious, that should not buy.
⒋ flatness: check the aluminum alloy surface, should be no depression or bulging.
⒌ gloss: aluminum doors and windows to avoid the purchase of the surface of the opening bubble (white) and ash (black spots), and cracks, burrs, skin and other obvious defects in the profile.
⒍ degree of oxidation: oxide film thickness should reach 10 microns. When you buy, you can tap the surface of the profile to see if the surface of the oxide film can be erased.
Second, aluminum doors and windows processing production process
1, broken bridge aluminum doors and windows processing production should be carried out in the factory, not in the construction site production, doors and windows should be designed to meet the design and insulation aluminum doors and windows installation and acceptance requirements, heat aluminum doors and windows should be installed solid doors and windows should push and pull, Open flexible, window should be a drain hole, and should be set limit device. Fasteners should comply with the relevant technical regulations; hardware models, specifications and performance should be consistent with the provisions of the existing national standards.
2, sliding window slide on the drainage hole processing should follow the inner fan outside the hole, the principle of the outer fan hole to ensure the sealing performance of doors and windows, especially the horizontal horizontal horizontal sliding window.
3, broken bridge aluminum doors and windows before assembly, should be removed from the end of the processing of burrs, end nodes and profiles must be taken with waterproof sealing and other measures to prevent the structure of water seepage.
4, hidden frame of the structure of the assembly assembly must be in the purification of indoor production and conservation.
Must clean the glass and aluminum frame with the surface of the dust, grease and other dirt; every clean a component or a glass, should be replaced clean dry wiping; solvent should be dumped on the cloth, mouth. Note the glue must be full, no bubbles, leaks, the seam surface should be smooth and smooth; the glue can not be used repeatedly.
