Aluminum Door Buy attention
Aluminum alloy door maintenance coup
1, aluminum door 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 the aluminum alloy door, 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, people do not step on the aluminum frame, do not pull the box for support.
3, aluminum doors 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 immediately wipe the wet glass and the door frame, with particular attention to wipe the 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 bolt in time to replace the damaged parts. Positioning pin, wind support, to spring and other aluminum parts 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 seal insulation of the key structure, 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 the door can not be closed, sealed. So the connection of the screw loose should be immediately tightened, such as screw feet loose, the application of epoxy strong glue to adjust a small amount of cement seal. First, the purchase notes
⒈ thickness: aluminum alloy sliding door has 70 series, 90 series of two, residential interior aluminum alloy sliding door with 70 series can be. Aluminum alloy used as a closed balcony push and pull should not be 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, after the release should be able to recover.
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 alloy door to avoid the purchase of the surface of the bubble (white) and ash (black spots), as well as 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 on the surface of the profile to see if the oxide film on its surface can be wiped off.
