First, the ceiling Daquan material introduction
Is the sound absorption effect of mineral wool board good? Made of mineral fiber, the biggest feature is good sound absorption effect. Its surface is knurled and embossed, and the patterns are starry sky, cross flower, central flower and walnut pattern. Mineral wool board can be sound insulation, heat insulation and fire prevention. High-grade products do not contain asbestos, which is harmless to human body and has anti-settlement effect. The price is also moderate, per square meter? Between 20 yuan and 50 yuan.
The suspended ceiling is composed of decorative board, keel, messenger wire and other materials, which can be replaced frequently as needed. It is a very convenient household item. According to the different decorative materials, the ceiling can be divided into gypsum board ceiling, metal plate ceiling, glass ceiling and PVC board ceiling. Gypsum board is relatively cheap, followed by PVC board, and metal plate is the most durable but expensive. The aluminum gusset ceiling in the metal plate is mainly used for home decoration.
But pure aluminum is soft, so the aluminum gusset plate on the market is actually the ceiling made of aluminum alloy, including aluminum-magnesium alloy and aluminum-manganese alloy. Al-Mn alloy pinch plate has higher hardness, and Al-Mg alloy increases hardness and brightness. Good texture and strong decorative effect. High-quality Al-Mn alloy pinch plate is commonly known as stainless aluminum because of its good corrosion resistance.
There are some inferior substrates in the market, which are made of waste aluminum, recycled aluminum or miscellaneous aluminum. Products are easily deformed and oxidized, and some even contain recycled aluminum containing harmful substances such as chromium, lead and mercury. This kind of aluminum gusset plate has low price, high hardness and a certain thickness, which is very deceptive. Generally, the width of aluminum gusset plates on the market is between 10- 15cm, the thickness is 0.55 mm, 0.6 mm, 0.7 mm and 0.8 mm, and the price is between 130 yuan/m2 and more than 200 yuan/m2.
In small markets, salespeople often say, "The thicker the gusset plate, the better. Look at how thick our gusset plate is ... "In fact, the thicker the aluminum gusset plate, the better. If the hardness is not enough, the pinch plate will be deformed. However, 0.6 mm or 0.7 mm thick gusset plate in home decoration is completely sufficient. Those aluminum-mixed boards are useless because of poor material.
Second, how to choose the ceiling
Is the aluminum ceiling most suitable for kitchen and bathroom use? This is a new type of ceiling material developed in recent years, which can not only prevent fire and moisture, but also resist corrosion, static electricity, sound absorption and sound insulation. It can be regarded as the best ceiling material. Aluminum ceiling can be divided into grid ceiling, square gusset plate, strip gusset plate and so on. The surface can be divided into two types: perforated and flat. A variety of patterns can be formed by punching holes on the surface, and the biggest function of punching holes is ventilation and sound absorption. There is a film pad inside the gusset plate, and moisture can be absorbed by the film by punching holes, which is most suitable for kitchens and bathrooms with more water. The surface of aluminum pattern board is heated and cured by paint, which has different luster effects and various color series such as mercerization, silk surface and mirror surface. The basic materials of domestic aluminum flower board are aluminum-magnesium alloy and aluminum-manganese alloy, and the price is about 50 to 60 yuan per square meter. The basic material of imported products is aluminum-zinc alloy, which has higher hardness than domestic products. What is the price per square meter? 200 yuan, up and down. Inspection of the quality of aluminum mosaic mainly depends on whether the shape and size of the surface grid are uniform, whether the arrangement is neat, whether the surface gloss is good after plastic spraying and whether the thickness is uniform.
Is the decorative effect of PS board good? This is a new imported material with strong color, great elasticity, light weight and good light transmittance, and it is an ideal ceiling material. PS board has a variety of patterns, such as bark patterns, running water patterns, beads and so on, which will not fade and age. Because of its good light transmission, lighting lamps can be installed in the ceiling to form uniform astigmatism and temperature radiation effects, which is very decorative. The price of PS board is relatively high, about RMB 0/00 per square meter/kloc ~ 200 yuan.
The above recommendation is about the material classification of ceiling and the matters needing attention in the purchase process. From this, we can know that, first of all, the common ceilings are waterproof, moisture-proof and anticorrosive stainless steel ceilings, aluminum alloy ceilings or wooden ceilings, and each ceiling has its own irreplaceable advantages and disadvantages. On the other hand, the ceiling can not only play a decorative role, but also play a practical and beautiful role. For example, the integrated ceiling installed on the toilet has yuba and lighting switch, which can refer to the actual situation.
