In recent years, aluminum alloy blinds have been widely used in many households today, and they are a more practical decoration in daily life. How to choose blinds? What are the preventive measures during use?

1. Treatment of blinds
   The surface of the processed material should not have oil stains, aluminum shavings, burrs, or other stains; When embedding, no rubber strip should be excessively stretched; Ensure that the rubber band is approximately 10mm longer than the embedded groove; The rubber strip should be wrapped around once, and the docking joint should be docked at the upper corner of the frame, and should not be cut into multiple sections.
   Except for stainless steel, connectors, hardware, and metal linings used in blinds should undergo surface anti-corrosion treatment; Glass mats should be made of hard rubber or plastic and should not use recycled rubber, sawdust, or other absorbent materials; After assembling the beads, they should be firm and the gap between the seams should not exceed 1mm.
   The overlap between glass and window is calculated according to the edge computing of window frame and sash, and the overlap of each side shall not be less than 8mm. Double layered glass should not expose aluminum gaskets, and glass gaskets must be added underneath the glass during assembly.

2. Installation of aluminum alloy louvers
   Before installation, it is necessary to determine the vertical, horizontal, and wall thickness positions. When installing the mesh, the reserved gap between the window frame and the hole should be 5-8mm, and the gap between the top and bottom should be uniform during installation. When installing burrs, the thickness of the connecting parts shall not be less than 2mm.
   The diagonal deviation of installing the window frame is ≤ 2.0mm; The vertical deviation of the front and rear frames is ≤ 2.0mm; The horizontal deviation of the window frame is ≤ 1.5mm; Elevation angle error ≤ 5.0mm.
   During the installation process of cleaning the opening, use an expansion hose to directly fix the window frame to the wall. When fixing, it is necessary to tighten the screws with a screwdriver. It is strictly prohibited to hit the window directly with a hammer. When deburring, use an expansion hose to fix the window frame to the wall through a connector. Regardless of the fixing method used, the fixing point when entering the main structure shall not exceed 600mm, and the fixing part shall not be less than 50mm.
   After installing doors, windows, and window frames, there should be no arching, sagging, warping, or deformation to prevent interference with the function of the switch; Before installing the glass, the mortar and debris in the groove should be removed to ensure unobstructed drainage holes; After the installation of the window sash, the appearance quality surface is clean, without large areas of pockmarks, scratches, abrasions, rust, etc; The surface of the applied sealant is smooth, flat, and free of bubbles.
   The finished accessories have been fully installed and securely fastened, without any errors or insufficient installation; After assembly, the sealing strip should be flat and firm, and the joints at the corners of the frame should be tightly bonded without slotting, with no gaps at the ends.
