First, the variety
Nowadays, there are many varieties of gussets on the market, such as laminated sheets, nano-plates, roll-coated boards, frosted boards, etc. Roll-coated boards are directly glazed to aluminum boards after 280 °C high temperature, environmentally friendly and non-toxic (low formaldehyde emission) National standard 15 times), not easy to change color. The laminated board is a layer of PUC film with glue. First, it is not environmentally friendly (including formaldehyde). The color is fast (the sun will change color after two hours of drying), so it is best not to choose the laminated board.
How to identify the pros and cons of the gusset?
A. Look: The surface of the inferior gusset plate looks uneven and has particles. The quality panels look flat and the panels are soft.
B. Smell: Use a lighter to burn a corner of the inferior board. It will burn in 30 seconds, and it will have a pungent odor of plastic charring. Even if it is burnt to yellow, it will not have a pungent smell.
C, touch: the temperature of the surface of the laminated board is the temperature of the plastic, so it is relatively high, to be warmer, the temperature of the surface of the rolled board is the temperature of the metal, to be cooler.
D. Listen: Use the corner of the panel to gently touch the center of the panel. The sound of the laminate is a bit boring, and the sound of the roller is crisp.
Second, the substrate
(Be light and flat) Not the thicker the better, there are many people think that the thicker the buckle, the better, in fact, the thickness is not necessarily good, the international standard of aluminum gusset is 0.5mm, the aluminum plate is too thick and there will be a black seam in the middle. . The aluminum material selected for the roll-coated board is made of aluminum, magnesium and manganese. The magnesium content is about 1.3-1.8% higher to increase the elasticity of the machine. The addition of manganese metal can increase the machine. The rigidity of the material is between about 0.1 and 0.3. Depending on the quality of the aluminum used, the aluminum plate with poor material can only increase the thickness to ensure rigidity. And no toughness. So it is not as thick as it is. It’s not good to shake your hand and feel the squeaking.
The surface coating, different areas with different gussets, the kitchen should use oil-resistant aluminum board, and the bathroom can choose some softer, warmer and more romantic colors, of course, the key to match the overall style of your home, such as wall tiles, floor tiles And the color matching of the cabinets.
How to choose the brand: the formal brand product board is generally branded with protective film, the metal ceiling has the brand's stamp, and the back has the factory date, brand name and ISO9001 international quality system certification computer code, the small manufacturers' products There are no such brand labels, or they are rather vague.
Third, electrical appliances
The integrated ceiling industry's electrical appliances, like the automotive industry, are mainly assembled by assembly. No integrated ceiling company has the ability to produce all the parts themselves.
Meniscus Lenses: The Positive Meniscus can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens. The meniscus lens plays a divergent role in the optical path, and is commonly used in photographic system, objective lens system and laser measuring system.
