First, the Aluminum Composite Panel surface is not flat, not vertical, the seam is narrow, and the height is inconsistent.

1. Reason: The horizontal and vertical of the skeleton are out of tolerance, the facade is not flat, the board surface is installed poorly, and the hole is misplaced;

2. (1) Starting from the installation of embedded parts and expansion bolts, it must be handled carefully. When the skeleton is installed, the horizontal and vertical wires are pulled, the plane is flat, and then the theodolite is inspected for process acceptance;

(2) Plate and skeleton positioning, drilling must be accurate;

(3) When the board is installed, it is not free, and it must be installed according to the plan and the position of the bullet. Check the size and shape of the plate before installation, and check the correctness.

Installed.

Second, the seams are not tightly sealed, uneven, and there are bubbles and water seepage.

1, the reason

(1) At the end of the caulking, the surface of the board is tightly sealed with polyethylene foam. When the sealant is filled with the caulking gun, a certain pressure is formed, so that the seam is not firmly bonded and the seal is not tight.

strict;

(2) The operator is unskilled in operation, the distance between the muzzle and the caulking is inconsistent during the caulking, the pressure is uneven, resulting in uneven thickness, many joints, and air.

The surface of the sealant is not flat, with bubbles and water seepage;

(3) Material problem: There is a problem with the quality of silicone sealant.

 2, the solution

(1) The material selection is good and the tool performance is good;

(2) Carefully insert the sealing filler, the filling surface is kept at the same distance from the surface of the plate, and the depth of the embedded sealing glue is uniform, so that the seam is compact and the seam surface is straight;

(3) The skilled worker is skilled, and the fixed-stitch gun is kept at a constant speed and the distance is the same. With the embedded air, the air is smashed and the wipe is used.

Sub-flattening removes the gas.

Third, the closing process is not firm, uneven, not sealed

1, the reason

Aluminum Composite Panel Manufacturer at the end of the construction according to the requirements, the installation is not detailed, the method is not appropriate.

2, the solution

(1) Make a closing plan before construction, and adopt a reasonable closing plan for different structures and conditions;

(2) Strict operation during installation, master the essentials.

Fourth, surface contamination, dents

1, the reason

(1) The protective film is removed prematurely, and the measures for protecting the finished product are improper;

(2) Improper protection of the finished product during the construction of the next process, caused by impact on the board surface.

2, the solution

(1) Do not remove the protective film too early, and remove it when removing the scaffolding;

(2) Develop feasible product protection measures during the work;

(3) Clean up the contaminated area in time and scrub it clean.
