Fabrication and installation phase of a) standard clearance hole in the wall surrounding doors and windows should be controlled at between 25mm-40mm, the maximum size should not exceed 50mm, a minimum of not less than 20mm, the frame and the outer walls have a certain distance, or should be adopted fine aggregate concrete pouring dressing before installation construction, prohibited the use of poor quality masonry, mud-brick or mortar directly sintered pad level; b) according to the project circumstances a reasonable choice of cement mortar filling method, first, the first mortar was filled in aluminum cavity and then install the inner wall and a second filling; the second is the aluminum frame fixed before filling mortar. Both methods have advantages and disadvantages supply aluminum casting, first ensure that the cavity is not formed aluminum hollowing phenomenon, but it is easy to produce in the secondary filling cracks and leakage; second method is easy and the lower sides of the border difficult to avoid the formation of form filling dissatisfaction hollowing phenomenon; c) filling cement mortar with cement mortar to be controlled better than casting aluminum Which, generally 1: 2.5, to ensure the quality of cement mortar is recommended to add waterproof cement mortar agents to improve the anti-leakage performance cement mortar casting aluminum supplier, pay attention to maintenance, to avoid cracking; d) border around the outer wall of windows and doors 300mm range, increasing Erdao waterproof coating applied to reduce the chance of water leakage; squeeze cylinder temperature unreasonable choice also affect the quality of the weld, for thick-walled cylinder temperature profile extrusion recommendations 440-460 ℃, and for thin wall sections and lower vent hole is too large, suggested the use of 400-420 ℃, other On the one hand, squeeze tube is not clean, coproduct scale much, or squeeze tube is deformed as the drum, as well as extrusion cylinder and pressure pads gap is too large, which all affect the weld quality.
