What material is good for decorating the ceiling?

The ceiling materials mainly include mineral wool board, gypsum board, wood board, PVC plastic gusset plate, glass, metal and so on. 1, PVC plastic gusset ① Features It is made of PVC and processed into tongue-and-groove profile, which has the characteristics of light weight, simple installation, waterproof, moisture-proof and moth-proof. Its surface pattern changes greatly, and it has good pollution resistance, easy cleaning, sound insulation and heat insulation properties. In particular, flame retardant materials are added to the new process, which makes it go out immediately after fire, making it safer to use. Because of its low cost and good decorative effect, it occupies an important position in the ceiling materials for home decoration and has become the leading material for ceilings such as bathrooms, kitchens, bathrooms and balconies. ② Quality Appraisal When purchasing PVC ceiling profiles, you must ask the dealers for quality inspection reports and product inspection certificates. Appearance quality: the board surface should be smooth, free from cracks and bumps, freely disassembled and assembled, with rough surface and no scratches; The sound of knocking on the board by hand is crisp. In the inspection report, the performance indicators of the product should meet the following requirements: thermal shrinkage is less than 0.3%, oxygen index is greater than 35%, softening temperature is greater than Celsius, ignition point is greater than 3000 Celsius, water absorption is less than 15%, and moisture absorption is less than 4%. (3) Installation should first pop up elevation lines on the wall, fix the line pressing at both ends of the wall and fix them firmly with cement nails. According to the actual size of the ceiling, cut the plate, insert the plate into the batten, and the tongue and groove of the batten are outward. After installation, fix it with nails, and then insert the second plate ... The last plate should be cut according to the actual size. When cutting, use a sharp knife, use a steel ruler to press the elastic wire cutting, and slightly bend and insert the tongue and groove of the last board when loading the plate. After installation, the wooden strips on both sides will be sealed. The maintenance and replacement of PVC ceiling profiles have strong water resistance and scrub resistance. In daily use, it can be scrubbed with cleaning agent and then rinsed with clear water; Gaps between plates are prone to oil stains. When cleaning, you can use a brush dipped in cleaning agent to clean it, and then rinse it with clear water. Pay attention to the lighting circuit not to be damp. If the PVC ceiling profile is damaged, it is very convenient to update it. Just take off the batten at one end, pull the boards out of the batten piece by piece, replace the damaged boards with new ones, reinstall them and press the batten. When replacing, pay attention to the color consistency between the new board and the old board, and there can be no color difference. 2. Metal product ceiling Metal product ceiling refers to a metal decorative board with multiple functions and decorative effects. Compared with traditional ceiling materials, the texture and decorative feeling are better, which can be divided into sound-absorbing board and decorative board (without holes). According to the acoustic principle, the sound-absorbing board uses various metal plates with different perforation rates to eliminate noise. There are different types of holes such as round hole, square hole, rectangular hole, rectangular hole, triangular hole, large and small combined hole, etc. The bottom plate is mostly white or aluminum. Another kind of metal decorative board pays special attention to decoration, with simple and smooth lines, beautiful shape and elegant colors, including bronze, gold, red and blue, milky white and other colors; The specifications are completely consistent with the width of ordinary houses, and are connected with marble and aluminum alloy doors and windows, which are elegant and gorgeous, adding icing on the cake to the quiet living environment. Metal decorative plates include aluminum, copper, stainless steel, aluminum alloy, etc. Copper and stainless steel decorative plates are of high grade and high price. For the general room decoration, aluminum alloy decorative board is more suitable, which conforms to people's general shopping psychology, that is, good quality and low price. There are rectangles and squares in the specifications. The maximum specification of rectangular plate is 6000mm* 100mm*0.5 mm, and the general room width is more than 5m. For the decoration of larger rooms, long strip plate is selected, which has strong integrity. The decoration of a small room can generally be 500 mm * 500 mm Due to the poor thermal insulation performance of metal plates, in order to obtain certain sound-absorbing and heat-insulating functions, glass wool, rock wool and other thermal insulation and sound-absorbing products can be used when selecting metal plates for ceiling decoration to achieve the effect of heat insulation and sound absorption. Especially for residents living on the top floor, the indoor environment can be improved after renovation, and the energy consumption of air conditioning can be obviously saved. 3. Gypsum board ceiling Gypsum board is a new type of ceiling decoration material widely used at present. Good decorative effect and sound absorption performance. Commonly used gypsum decorative board and paper decorative sound-absorbing board. Gypsum decorative board has the characteristics of light weight, moisture-proof, no deformation, fire prevention and flame retardant. It has the advantages of convenient construction, good processability, sawing, nailing, planing and bonding. The main varieties are: all kinds of flat plates, embossed plates, semi-perforated plates, fully perforated plates, waterproof plates and so on. Relief diamond plate is suitable for the ceiling of living room, bedroom and study. Waterproof boards are mostly used in places with high humidity such as kitchens and bathrooms. Paper decorative sound-absorbing board has the characteristics of fire prevention, sound insulation, heat insulation, good anti-vibration performance and convenient construction. Causes and prevention of uneven ceiling 1, phenomenon: irregular corrugated ceiling 2, cause analysis: ① random arching, resulting in uneven camber. (2) The grid or edges around the ceiling are uneven. ③ The high moisture content of wood leads to shrinkage and deformation. (4) The keel joint is uneven and hard to bend, resulting in uneven ceiling. ⑤ Derrick or derrick spacing is too large, which leads to irregular deflection after keel deformation. ⑥ The stress nodes are not tightly combined, and displacement and deformation occur after stress. 3, preventive measures ① Ceiling wood should choose high-quality cork, such as pine, Chinese fir, etc., and its moisture content should be controlled within 12%. (2) The keel should be straight, and there should be no distortion and cross-section scar. (3) The suspended ceiling shall be leveled with elastic lines on the surrounding walls according to the design elevation, subject to the horizontal lines nailed around. The springing height of the horizontal lines shall be short span of the room 1/200, and the longitudinal springing shall be hung evenly. Sauna boards are generally used on balconies, because balconies are generally sunny, wood is not afraid of exposure to the sun, Aoki is beautiful but easy to fade, and plastic-steel boards can't be exposed to the sun, so I suggest you use a thickened and widened sauna board, which is relatively firm and not deformed, and gypsum boards can't be used on balconies at all. Gypsum board is basically used for indoor aisle ceiling and modeling roof. It is also good to use aluminum gusset plate, because the clothes on the balcony are also wet, and the performance of aluminum gusset plate is better than that of wood board and PVC, and it does not rust or rust.
