The second generation is plastic board (PVC)
The third generation product is metal ceiling
The difference between several generations of products: now gypsum board, mineral wool board is also constantly improving, there are waterproof gypsum board and sound-absorbing mineral wool board. However, they have a single plate type, which is not easy to scrub, and are installed for light and dark frame keels. PVC products have poor oxidation resistance, are not moisture-proof, fire-proof, easily changeable and discolored, and are mostly used in old-fashioned ordinary home decoration. It is best to use aluminum gussets for ceiling decoration.
(1) Light steel keel gypsum board Ceiling gypsum board is made of plaster gypsum as the main raw material mixed with additives and fibers. It has the properties of light weight, heat insulation, sound absorption, non-combustibility and hammerability. Gypsum board and light steel keel (Made of pressed thin-chain steel) combined to form a light steel keel gypsum board.
Environmental protection requirements: Gypsum board generally requires the use of high-quality environmentally friendly gypsum, which is conducive to protecting the environment and does not contain any substances harmful to the human body. The unique indoor temperature regulation function of gypsum board makes the living environment healthier.
The gypsum board must meet the national standard GB6566-2001 "Limits for Radionuclides in Building Materials". It is a green building product.
Ordinary gypsum board: length 3000*1200, thickness 9.5, 12, 15, general gypsum characteristics
Water-resistant gypsum board: length 3000*1200, thickness 9.5, 12, general water-proof and moisture-proof
Moisture-resistant gypsum board: length 3000*1200, thickness 9.5, 12, anti-sag
Refractory gypsum board: length 3000*1200, thickness 9.5, 12, 15, general fire resistance
Gypsum board: length 2400*1200, thickness 9.5, 12, 15, fire resistance, better indoor breathing performance
Material composition: The full name of calcium board is fiber-reinforced calcium silicate board, which is composed of silica materials (diatomite, bentonite, quartz powder, etc.), calcium materials, and reinforcing fibers as the main raw materials. After pulping, forming, Lightweight plate made by steam curing, surface sanding and other processes.
Advantages: Silicon calcium board has the advantages of light weight, high strength, moisture resistance, corrosion resistance, fire resistance, frost resistance, heat insulation, sound insulation, long life, etc. Another significant feature is that it is convenient to process, not easy to reprocess like gypsum board Powdery fragmentation.
(3) Cotton board ceiling
Material composition: the slag is rotated through high temperature, high pressure and high speed to remove impurities and wash into mineral wool. Mineral wool board is mainly composed of mineral wool, adhesive, pulp, and perlite.
(4) Splint ceiling
Material composition: plywood (also called plywood) is made by cooking and softening the logs, cutting them into large sheets along the annual ring, and drying, finishing, gluing, forming, hot pressing, and sawing.
Advantages: It has the advantages of light material, high strength, good elasticity and toughness, impact resistance and vibration, easy processing and finishing, insulation, sound insulation and so on. It can also easily create curved, round, square and other shapes of smallpox, but the disadvantage is that it is afraid of termites. 5mm plywood is generally used for ceilings, 3mm is too thin to easily arch, 9mm is too thick.
(5) Ceiling of aluminum gusset
The profiled materials of aluminum gussets are mainly divided into special-shaped long aluminum gusset ceilings and square painted aluminum gusset ceilings. There are three types: strip, square and grid. The strip-painted aluminum gusset ceiling is a strip-shaped aluminum gusset, generally suitable for use in walkways and other places, and the design helps to reduce the feeling of long and narrow.
Exposed structural formula:
If the structural methods and components themselves have beautiful value, then the ceiling should apply the treatment method of revealing the structure. In this way, a good artistic effect can be achieved without or with little decoration. The wooden components of the house have the characteristics of rough and natural texture, warm and intimate, revealing it outside, you can get a simple and elegant living environment.
Cover structure:
If the structural layout lacks expressiveness, the component itself lacks aesthetics, plus some special functional needs, then this ceiling should partially or completely cover the structure. China's algae-type ceilings. China's unique architectural structure and decoration techniques, one of the important modeling methods of Chinese architectural styles in interior decoration. It is called "Algae Well" and contains five elements to prevent fire with water. It is usually on the throne of the temple or above the throne of the palace. It is a recessed part of a flat roof, with a square shape, hexagonal shape, octagonal shape or round shape, and then decorated with a bucket arch, carved or painted on it, and commonly known as "Shuanglong Xizhu". This part can produce beautiful and gorgeous visual effects.
三、软膜天花
软膜天花五年前来自法国的产品，采用法国特殊聚氯乙烯材料，拥有传统石膏板和铝板天花的所有功能，此天花可以随便由设计师任意发挥设计灵感。
优点：防火、节能、防菌和丰富的色彩、无限的创造力、安装方便、优异的抗老化功能，安全环保、理想的声学效果和灯光结合的完美效果等功能。
Cultural and famous issues:
1. The pattern design of smallpox is very particular. Some people don't advocate the complicated design of smallpox. They only simply pursue the beautification and three-dimensional sense. They think that the combination of height and height is not uniform. And think that the smallpox design error will bring bad luck and bad results to the family.
2. The pattern of the ceiling is not good as a triangle, a cross shape, or a sharp corner. When guests come to your home, they will feel that you are doing a partial business, not a bright and honest career. This kind of ceiling design is prone to disasters and will cause disasters.
3. A kind of smallpox pattern like chicken cage and bird cage.
4. The ceiling pattern is made into a wavy curve shape, and there are layers like the impact of the waves. This design should not be advocated. Although it is very romantic, it is prone to latent disasters and emotional storms.
5. The ceiling pattern is made into an octagon (bagua shape), this pattern is only suitable for use in temples and Taoist temples.
