Common quality problems encountered in the decoration of aluminum composite panels

The following four significant installation issues with aluminum composite panels are examined in this article primarily from two perspectives: causes and solutions.

To start with, the surface is uneven, the joints are not vertical, and the height is variable.

Causes:

Horizontal and vertical super poor of the skeleton, uneven elevation, super poor installation of the panel surface, misalignment of the eyelet.

Solution:

1. It ought to be handled carefully, beginning with the installation of buried components and expansion bolts. Install the skeleton using horizontal and vertical draw lines, making sure the plane is flat, and then check the procedure' acceptability using latitude and longitude meters.

2. Drilling and plate and skeleton arrangement must be precise.

3. Board installation must follow the program and the placement of the bullet lines; it cannot be random. The board's size and shape should be accurately and thoroughly examined before installation.

Second, there are issues with loose, uneven, bubbles, and water seepage.

Causes:

1. the embedded seam is blocked with polyethylene foam at the end of the board surface, and a certain pressure is formed at the end when the sealant is filled with the seam gun so that the bond with the board seam is not firm and the seal is not tight.

2. unskilled operation of workers, the inconsistent distance between the muzzle of the gun and the embedded seam when embedded, uneven pressure, resulting in uneven thickness, more joints, bringing in air, resulting in the surface of the sealant is not straight, bubbles and water seepage phenomenon.

3. Material problems: silicone sealant quality problems.

Solution:

1. good selection of materials and good performance of tools.

2. carefully stuffed with sealing filler, filling the surface from the board surface distance to maintain consistent, embedded sealant depth consistent, so that the joints are dense, and the seam surface is straight.

3. Operate the workers skillfully, hold the inlay gun steady, keep the speed even, the distance is consistent, and exclude the air with the inlay, once the air bubble appears, stab it and flatten it with the trowel to exclude the gas.

Thirdly, the finish is not firm, not smooth, not sealed

Reason:

1. The end of construction according to the requirements, installation is not meticulous, improper method.

Solution:

1. make a good closure plan before construction, and adopt a reasonable closure plan for different structures and conditions.

2. Strictly operate and master the essentials during installation.

Fourthly, surface contamination, dents

Cause:

1. premature removal of protective film, improper measures to protect the finished product.

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

Solution:

1. do not remove the protective film too early, in the removal of scaffolding removal is good.

2. work out feasible measures to protect the finished product.

3. For pollution place timely cleanup, and scrub clean.
