Common Quality Problems Encountered In The Decoration Of Acm Aluminium Composite Material(1)

(1) The Bond Aluminium Composite Panel surface is uneven, not vertical, the joints are wide and narrow, and the Aluminium Signage Panels height is inconsistent

1. Reason: the horizontal and vertical of the Acm Panel Sign framework are out of tolerance, the Composite Panel Aluminium elevation is not flat, the installation of the board is out of tolerance, and the holes are misplaced;

2. (1) Starting from the installation of embedded Acm Composite Panels parts and expansion bolts, it must be carefully operated. When installing the skeleton, pull the wires horizontally and vertically, and the plane should be flat, and then check with theodolite for process acceptance;

(2) The positioning of the Acp Sheet For Exterior and the frame, the drilling must be accurate;

(3) When the board is installed, it must not be installed at will, and the installation must be carried out according to the plan and the position of the spring line. Before installation, check the size and shape of the plate, and the installation can be done only if the inspection is correct.

(2) The joints are not tightly sealed, uneven, with bubbles and water seepage.

1. Reason

(1) When caulking, do not use polyethylene foam to block the back of the Aluminium Plastic Composite board. When the sealant is poured with a caulking gun, a certain pressure is not formed, so that the bonding to the Alpolic Aluminium Composite Panel seam is not strong and the seal is not tight;

(2) The operator is unskilled, and the distance between the muzzle and the caulking part is inconsistent during caulking, and the pressure is uneven, resulting in uneven thickness, multiple joints, and air, causing the Panel Aluminium Composite surface of the sealant to be uneven, with bubbles and Water seepage phenomenon;

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

2. Solution

(1) Good material selection and good tool performance;

(2) Carefully insert the sealing filler, keep the distance between the filling surface and the Albond Aluminium Composite Panels surface the same, and insert the sealant at the same depth, so that the seam is dense and the seam surface is straight;

(3) The operator is skilled in the skill, hold the steady caulking gun, keep the speed uniform, the distance is the same, and remove the air along with the embedding. Once the bubbles appear, they will be pierced and flattened with a trowel to remove the air.
