Give the ceiling "new clothes"
There are already many varieties of pinch plates on the market. Commonly, there are coated plates, rolled plates and anodized plates. Among them, the roller-coating plate is directly baked to the aluminum plate at a high temperature of 280 degrees. It is environmentally friendly and non-toxic (the formaldehyde emission is 15 times lower than the national standard), and it is not easy to change color. The film is glued with a film of PUC. One is not environmentally friendly (including formaldehyde) and the other is discolored quickly (it will change color in the sun for two hours). Therefore, it is best not to choose a film.
How to identify the advantages and disadvantages of gussets?
A. Look: The surface of inferior buckles looks uneven and there are particles. The high quality board looks very flat and the panel is soft.
B. Smell: Using a lighter to burn the corner of a poor quality board, it burns in 30 seconds, and there is a pungent odor of burning charcoal. Even if it is burned to a low temperature, rolling oil-resistant ceilings will not have a pungent odor.
C, touch: the temperature of the surface of the coated plate is the temperature of the plastic, so it is relatively high, to be warm, the temperature of the plate surface is the temperature of the metal, to be cool.
D. Listen: With the corner of the hand-held panel, gently tap the center of the panel, the sound of the membrane is boring, and the sound of the roller-coating board is crisp.
Second, integrated ceiling purchase - integrated ceiling substrate
In order to confuse the audiovisual industry, many businesses often use the thickness of the pinch plate as the reason for the high price. As everyone knows, the common aluminum pinch plate is divided into low, medium, and high grades, including only the roll-coating, film-laminating, The oxide plate is made of three materials, and the unity of the three materials is formed by performing different treatments on the surface of the aluminum substrate.
According to the introduction of integrated ceiling technology developers, the aluminum buckle substrate is generally selected aluminum-magnesium alloy, the thickness of the aluminum buckle plate between 0.6mm and 0.7mm, to ensure no deformation. The use of recycled aluminum materials for inferior aluminum ceilings not only fails to make thin, but also causes corrosion and surface peeling. At the same time, among the three materials, the coating material of the film-covered sheet and the coating of the roll-coating sheet are more likely to be used by poor manufacturers than non-environmentally friendly low-quality coating layers and coatings, which will not only quickly fade and peel off, but also will The release of harmful gases during use caused “decoration pollutionâ€.
