How to make the projector hideable in ceiling decoration

How to identify the advantages and disadvantages of the gusset, you may wish to start from the following ways:

1.Look: The surface of the inferior gusset looks uneven and will have particles.

The high-quality board looks flat and the panel is soft. Smell: Burn the corner of the inferior board with a lighter, it will be scorched in 30 seconds, and there will be a pungent smell of plastic burning, and the roll-coated oil-resistant ceiling will not have a pungent smell even if it is burned to yellow.

2.Touch: The temperature of the laminated board surface is the temperature of the plastic, so it is relatively high, and it should be warmer, and the temperature of the roller coating board surface is the temperature of the metal, which is cooler.

Listen: Hold the corner of the panel with your hand, gently tap the center of the panel, the sound of the laminated board is a little muffled, and the sound of the rolling board is a little crisper.

3.Many times, if you don't know what kind of ceiling to buy, you will listen to the promoter's electrical appliances, send plates and other promotions, and then forget the most real, in fact, we are just to buy a ceiling, and the money for those gifts is contained in it.

4.Generally speaking, the first thing to choose when choosing an integrated ceiling is the material of the gusset, and now the most used are aluminum alloy materials, but can you distinguish between new aluminum and old aluminum? The new aluminum has less impurity content and high price; Old aluminum, on the other hand, is recycled aluminum, which has a high impurity content and low price.

Since the current aluminum alloy ceiling is made by anodizing, roller coating, and laminating processing technology, it is difficult to see the difference in appearance, and only after a year or two can it be distinguished. Therefore, when asking merchants, you must pay attention, high-purity aluminum-magnesium alloy ceilings are easy to use.
