How to correctly select patterned aluminum plate?

Compared with other decorative boards, patterned aluminum board has the characteristics of strong metallic texture, light weight, flame retardant, rich color, no fading, high strength, easy processing and environmental protection, and has become a fashionable decorative material in the market at present. Aluminum plate has a wide range of applications, and it is a decorative material that can be used for indoor and outdoor decoration. It can be used as the exterior decoration of curtain walls, billboards and exhibition tables of buildings outdoors; Indoors, it is mostly used for the decoration of facades, hallways, TV walls and other eye-catching places, and can also be used as decorative materials for furniture and suspended ceilings, and its decorative function has a strong modern atmosphere. With the gradual individuality and novelty of decoration style, aluminum plates with specific styles will appear more and more in our lives.

At present, the quality of patterned aluminum plates in the market is different. Now, several schemes are selected for popular science for your reference:

1. Pay attention to whether the name and address of the manufacturer are complete when purchasing. Because only the plates with complete information can get due quality maintenance.

2, appearance inspection, observation of texture structure. The appearance of the decorative board should have a good aesthetic feeling, and the material should be meticulous and uniform, with clear color and beautiful wood grain. The textures of the matching board and the splicing board are arranged according to certain rules, and the wood color is close, with no obvious color difference, and the splicing seam is almost parallel to the board edge.

3. See if there are obvious flaws on the surface. The surface of the decorative board shall be smooth, free from burrs, grooves and knife marks, free from glue penetration, and free from local yellowing and blackening. The surface should be free of cracks, cracks, knots, skin and other defects as far as possible, and the natural warpage of the overall pattern aluminum plate should be as little as possible to avoid the phenomenon of sand disclosure caused by improper operation of sanding process.

4. The structure of the adhesive layer is stable, and there is no phenomenon of glue opening. It should be noted that there can be no protrusion and delamination between the surface veneer and the substrate and between the veneers of each substrate.

5. The knife pry method is an intuitive method to test the adhesive strength. Use a sharp flat blade to pry open the adhesive layer. If the adhesive layer is damaged and the substrate is not damaged, it indicates that the adhesive strength is poor.

6. The smell should be light, and plates with low formaldehyde emission should be selected. You can judge from the smell when you buy, and you should avoid decorative boards with pungent gas. Because the bigger the smell, the higher the formaldehyde emission, the more serious the pollution and the greater its harmfulness.

In short, the selection of patterned aluminum plates should not only pay attention to the origin, varieties and performance standards, but also combine their different uses, economic ability, market conditions and physical inspection of goods to keep the price reasonable and the quality good, so as to make the room shine. 

Brief discussion on some operation techniques of patterned aluminum curtain wall

A, decorative aluminum curtain wall engineering installation construction preparation:

(1) Prepare detailed mobilization plans for materials, products and machines;

(2) Implement various demand plans;

(3) Prepare the construction progress plan;

(4) Do a good job of technical disclosure;

(5) Do not collide, damage or pollute parts during handling and hoisting;

(6) During storage, the components shall be arranged and placed according to the installation sequence, the casting frame shall have sufficient bearing capacity and rigidity, and protective measures shall be taken when stored outdoors;

(7) Before installing the components, check the certificates and quality data. Unqualified components shall not be installed.

Second, the embedded parts installation:

(1) According to the civil construction progress, install embedded parts step by step from bottom to top.

(2) According to the design grid size of the patterned aluminum curtain wall, use theodolite or other measuring instruments for grid positioning.

(3) After checking and positioning, embed embedded parts according to the requirements of drawings.

(4) When installing embedded parts, stable measures should be taken to prevent the embedded parts from shifting during concrete pouring, and the horizontal or vertical surfaces of embedded parts should be controlled to prevent skew, skew and inclination.

(5) Check whether the embedded parts are secure and the position is correct. The position deviation of embedded parts shall be rechecked according to the design requirements. When there is no clear requirement in the design, the elevation deviation of embedded parts should not be greater than 10mm, and the deviation between the position of embedded parts and the design position should not be greater than 20 mm.

Third, the construction survey pay-off:

(1) Check the datum line handed over by the civil contractor, and use measuring instruments such as theodolite and level.

(2) Establish standard line: move the indoor elevation control line to the construction surface of each external wall and check it. Before lofting, the external dimensions of the building shall be re-measured, the baseline shall be determined according to the measurement results, and the partition size of the curtain wall shall be adjusted reasonably.

(3) Take the standard line as the baseline, put the grid line on the wall according to the drawing, and mark it.

(4) In the pattern aluminum plate project, after laying grid lines, check whether the position of embedded parts is consistent with the design. If there are any errors, prepare the deviation diagram of embedded parts, design corrective measures, and remedy the embedded parts after being confirmed by the supervisor or the owner.

(5) Finally, the steel edge of 0.5~1.0mm is φ, and two control lines are installed in the vertical and horizontal direction of a single curtain wall as the benchmark for curtain wall installation. Each floor shall be provided with a horizontal steel edge (when the width is too wide, a fulcrum shall be provided every 20m to prevent the steel edge from sagging), and a vertical steel edge shall be provided every 20m.

(6) Precautions:

When setting out, the deviation of civil structure should be decomposed, and the coordinate method should be used to set out to prevent error accumulation.

When setting out, the interface with other decorative surfaces and edge trimming should be considered at the same time.

Steel edge baseline control shall be marked at fastening points at both ends. Once the steel wire breaks, it should be trimmed in time.

The patterned aluminum plate project should be set out in strict accordance with the drawings, and the key point: datum line should be controlled.
