Scope of application of the alloy plate:

1. Straight plate: suitable for single-slope, double-slope and single-curved roofs with a radius greater than the radius of natural arc;

2. Positive and negative arc plates: suitable for single-curved roofs with radius less than natural arc radius;

3. Sector plate and arc plate: suitable for hyperbolic roofs;

4. Special case: the hyperboloid is made of alloy aluminum plate, so the curvature of the roof is small, and multiple roofs are allowed.

Summary of knowledge points of using alloy aluminum plate

1.Handling of aluminum plate: When handling alloy aluminum plate, the four edges of aluminum plate should be lifted at the same time. It is forbidden to push, pull and pull, so as not to scratch the board surface.

2, aluminum storage: aluminum should be stored in a dry and ventilated place, and placed on a flat surface, do not trample or bump.

3. Slotting of aluminum plate: When slotting with slotting machine or gong machine, use a semi-circular head milling cutter greater than 90 degrees. Don't cut the aluminum plate too deep or too shallow to avoid folding difficulties. Bend the plastic core with a thickness of 0.2-0.3mm together with the aluminum plate to increase the strength and toughness, otherwise the aluminum plate may break or the paint film may break during bending.

4. Aluminum plate batch: There may be color difference between different batches of the same model. When selling and using different batches of printing plates, color difference comparison procedures should be added. Our company mainly deals in alloy aluminum plates, aluminum reticulated plates, etc., which can only be used on the same plane without visual color difference.

5. Bending of aluminum plate: The edge bending stress is uniform, and it should be formed at one time. Don't bend it repeatedly, otherwise the alloy aluminum plate may break.

6. Arc machining of aluminum plate: special bending equipment is used for arc machining, and the plate should gradually reach the required curved surface, and it is not allowed to be bent and formed at one time.

7. Installation direction of aluminum plate: When installing aluminum plates of the same color on the same plane, the process direction should be consistent, otherwise visual color difference may be caused.

8. Tearing off the aluminum plate: Tear off the protective film within 45 days after the aluminum plate is installed, otherwise it may be difficult to tear off the film or remove the glue.

9. Usage conditions of aluminum plate: The inner wallboard should be used indoors and not installed outdoors to ensure the use results and service life.

10. Maintenance:

(1) When the surface of aluminum alloy profile is corroded and polluted, it shall be cleaned in time. You can wipe it with a soft cloth dipped in alcohol and then rinse it with water.

(2) Warm water containing lubricant or neutral detergent should be used for cleaning, and acidic or alkaline cleaning agents are strictly prohibited for cleaning aluminum alloy plates.

(3) Soft cloth and towel are suitable for scrubbing aluminum alloy plates. It is forbidden to wipe the surface of aluminum alloy plate with corundum powder, sandpaper, wire brush and other strong friction items.

(4) Alloy aluminum plate should be cleaned regularly according to the use environment.
