Ceiling material I, light steel keel gypsum board ceiling
Gypsum board is made of gypsum as the main raw material mixed with additives and fibers. It has the properties of light weight, heat insulation, sound absorption, incombustibility and sawability. The combination of gypsum board and light steel keel (pressed from galvanized thin steel) forms light steel keel gypsum board. There are many kinds of light steel keel gypsum board ceilings, including paper gypsum board, decorative gypsum board, fiber gypsum board, hollow gypsum board, and there are many specifications on the market. At present, the use of light steel keel gypsum board ceilings as partition walls is more, and the use of modeling ceilings is less.
Ceiling material II. Square ceiling
It is mostly used in commercial space, and generally uses 600mm and 600mm specifications, which can be divided into open bone and dark bone. The keel is usually made of aluminum or iron. Main board materials can be divided into gypsum board, calcium silicate board and mineral wool board. Gypsum board has been described in the previous paragraph, and calcium silicate board and mineral wool board are introduced below.
1. Calcium plate. The full name is fibre-reinforced calcium silicate board, which is a lightweight board made of siliceous materials (diatomite, bentonite, quartz powder, etc.), calcareous materials, reinforced fiber, etc. as the main raw materials, through pulping, green, steam curing, surface sanding and other processes. Calcium silicate board has the advantages of light weight, high strength, moisture resistance, corrosion resistance, fire prevention, etc; Another notable feature is that it is easy to reprocess, unlike gypsum board, which is easy to be pulverized and cracked.
2. Cotton board. The slag is rotated at high temperature, high pressure and high speed to remove impurities and wash into mineral wool. Mineral wool board is mainly composed of minerals, adhesives, pulp and perlite. Mineral wool board has similar characteristics to calcium silicate board, but its sound absorption performance is better than gypsum board and calcium silicate board.
Ceiling material III, plywood ceiling
Plywood ceiling is commonly used in current decoration. Plywood (also known as plywood) is made by cutting logs into large sheets along the growth ring after being cooked and softened, and drying, finishing, gluing, assembling, hot pressing, and sawing. It has the advantages of light material, high strength, good elasticity and toughness, impact and vibration resistance, easy processing and coating, and insulation. The ceiling is generally made of 5mm plywood, 3mm is too thin to arch, and 9mm is too thick. In fact, the reason for its popularity is that it can easily create a variety of modelling ceilings, including curved, round and square ones.
The paint on the plywood ceiling may fall off after some time. The method is to brush varnish (varnish) before decoration, and then do other processes after drying. Another disadvantage of plywood is that the interface will crack. The solution is to fill the interface with atomic ash during decoration.
Ceiling material IV, microporous aluminum plate
Microporous aluminum plate, also known as the concealed bone square gusset ceiling system, has the characteristics of flat panel surface, clear edges and lines, and fine seams. The ceiling system reflects the appearance effect of neat, generous, rich and elegant, and broad vision. The concealed bone square gusset ceiling system has the advantages of flame retardance, corrosion prevention and moisture prevention, and is convenient for assembly and disassembly. Each plate can be disassembled independently, which is convenient for construction and maintenance.
Ceiling material V, painted aluminum gusset ceiling
According to the investment introduction of the integrated ceiling manufacturer, the aluminum gusset plate profiled materials are mainly divided into three types: strip, square and grid
1. The strip painted aluminum gusset ceiling is a kind of long strip aluminum gusset, which is generally applicable to walkways and other places, and can help reduce the feeling of narrow and long in design. This material is no longer used for home decoration, mainly because it is not resistant to dirt and easy to deform.
2. The square aluminum plate is divided into two specifications: 300mm, 300mm, 600mm and 600mm. The former is applicable to kitchen, toilet and other places prone to dirt, while the latter is often used in commercial places such as offices. Square aluminum gusset is the mainstream product at present. The square aluminum gusset plate is divided into microporous and non-porous. The main advantage of the microporous aluminum gusset plate is that it can ventilate, so that the moisture in the high tide and wet areas such as the bathroom can enter the top through the pores, avoiding the formation of water droplets on the plate surface.
3. When the grid aluminum gusset plate is used, it is also necessary to be careful that someone uses stainless iron to fake it. To verify whether it is pure aluminum, impure aluminum or stainless iron, a magnet can be used to verify that the real aluminum does not attract magnetism, while the secondary aluminum or fake aluminum can attract magnetism. However, this method is not a panacea, because illegal businesses can also fake this feature by degaussing.
Ceiling material 6. Painted glass ceiling
In addition to the selection of materials, the decoration of the ceiling is mainly about the size and proportion of the shape. The former should be handled according to specific conditions, while the latter should be calculated based on ergonomics and aesthetics. In terms of height, the internal headroom of family decoration should not be less than 2.5m. Otherwise, try not to make modeling ceiling, but use gypsum line frame decoration.
Ceiling material VII. Waterproof gypsum board
Waterproof gypsum board: generally used for space decoration with high environmental humidity, such as toilets, bathrooms and kitchens. It also has high waterproof performance, with surface water absorption ≤ 160g/m2 and water absorption of about 5%. What material is good for the ceiling of the toilet? So it is easy to answer: choose different materials according to different needs. The construction of waterproof gypsum board generally uses light steel keel framework. During construction, pay attention to painting anti-rust paint on the suspender.
Ceiling material VIII. Advanced PVC board
Advanced PVC board: PVC ceiling profile is generally used for the ceiling of kitchen and toilet without fire protection requirements, and the plastic gusset plate ceiling is 40mm × 40mm square board forms a skeleton, and plastic gusset plates are nailed under the skeleton. This kind of ceiling is more suitable for decoration of the bathroom ceiling. Specification format: 1300 * 20001220 * 24401000 * 2000 can also be customized according to user requirements.
