Kitchen. Selection of suspended ceiling in bathroom.
The ceiling materials of kitchen and bathroom mainly include PVC plastic gusset plate, aluminum gusset plate and aluminum-plastic gusset plate. Now described as follows:
One: PVC plastic gusset plate
(1) material analysis: PVC plastic gusset plate has strong water resistance and scrub resistance, and its relative cost is low. PVC plastic gusset plate has the advantages of light weight, convenient installation, waterproof, moth-proof, varied surface patterns, pollution resistance, easy cleaning and good sound and heat insulation performance. In particular, flame retardant materials are added to the new process, so that it can be extinguished immediately after fire, and it is safer to use. The disadvantage is that compared with metal ceiling materials, the service life is relatively short. If the PVC plastic buckle plate is damaged, it is very convenient to replace it. Just remove the batten at one end, pull the boards out of the batten one by one, replace the damaged boards with new ones, and then reinstall the batten. Attention should be paid to minimize the color difference when replacing.
(2) Construction technology: The frame is made of 3*5 cubic meters, and bracing is needed when the span exceeds1.2m. Nail battens around the frame, intercept gusset plates with corresponding length, and insert them into battens one by one. You can choose the same color or multi-color for assembly according to the overall decoration style.
(3) Single flat cost: Wood square 8 yuan PVC plastic gusset plate can be divided into recycled materials and raw materials, and the price ranges from 10 yuan/flat to several hundred yuan/flat. 30 yuan's construction fee will be added to each house.
Two: aluminum gusset plate
(1) material analysis: aluminum gusset ceiling is also called integrated ceiling. Compared with traditional ceiling materials, aluminum gusset plates are superior in texture and decorative feeling. Aluminum alloy gusset plates are divided into sound-absorbing plates and decorative plates. There are round holes, square holes, rectangular holes, rectangular holes, triangular holes, large and small combined holes, etc. It is characterized by anticorrosion, shockproof, fire prevention, sound absorption and smooth surface. The bottom plate is mostly white or lead gray; The decorative board pays special attention to decoration, and the lines are simple and smooth. According to color, there are bronze, gold, red, blue, ivory and colored patterns. There are strip, square and grid shapes according to their shapes, but grid shapes cannot be used for kitchen and bathroom ceilings. The largest specifications of rectangular plates are 600mm*300mm and 600 mm * 600 mm. The large kitchen and bathroom are decorated with strips with stronger overall feeling, and the small room can generally be decorated with 300 mm * 300 mm. The aluminum gusset ceiling is assembled on site, which has poor waterproof and moisture-proof performance.
There are mainly three kinds of aluminum gusset plates sold in the market, namely: coated plate, roll coated plate and oxide plate.
Simply put, laminating board is to laminate PVC film on aluminum substrate;
Roller coating plate is a high-quality coating on aluminum substrate;
The oxide plate is a special anodic oxidation treatment for the substrate.
In order to facilitate your choice, we briefly introduce three kinds of plates for reference only.
Laminate:
The film-coated board is made by covering a layer of film, high gloss film or magic color film on the aluminum alloy substrate and coating professional glue on the board surface. The coated board has bright luster, a variety of colors to choose from, waterproof and fireproof, excellent durability (weather resistance, corrosion resistance and chemical resistance) and anti-pollution ability, and excellent anti-ultraviolet performance. Different brands of film-coated board have different substrates and thicknesses, and the film-coated materials and thicknesses are also different.
1) Basic materials:
Grade 1: Al-Mg alloy with some manganese. The biggest advantage of this material is its good oxidation resistance. At the same time, because it contains manganese, it has certain strength and rigidity, so it is the most ideal material for smallpox.
Grade II: Al-Mn alloy, whose strength and hardness are slightly better than Al-Mg alloy. But its oxidation resistance is slightly lower than that of Al-Mg alloy. If both sides are protected, the defect that its oxidation resistance is not as good as that of Al-Mg alloy is basically solved.
Grade III: aluminum alloy, containing less manganese and magnesium. Therefore, its strength and stiffness are obviously lower than that of Al-Mg alloy and Al-Mn alloy. Because it is soft and easy to process, it can basically meet the most basic flatness requirements of smallpox as long as it reaches a certain thickness. But its oxidation resistance is obviously inferior to that of Al-Mg alloy and Al-Mn alloy. But also easy to deform during processing, transportation and installation.
Grade 4: Ordinary aluminum alloy, whose mechanical properties are not very stable.
Grade 5: Recycled aluminum alloy. The raw material of this kind of plate is aluminum ingot melted and tied into aluminum plate by aluminum processing plant, and the chemical composition is completely out of control. Because the chemical composition is out of control, the performance of these materials is extremely unstable, which leads to serious uneven surface, product deformation and easy oxidation.
The thickness of the substrate is between 0.3 and 0.5 mm. Generally, the thickness of the substrate of well-known brands is about 0.5 mm..
2) Coating material:
The types of plastic film mulching used in industry are as follows:
LG high gloss film, the surface effect is crystal clear, changeable and colorful, and it will not change color for a long time. Soft feel, rich surface color, environmental protection, moisture-proof, anti-corrosion, easy cleaning, light weight and good fire resistance. At present, the best film-covered products are expensive and have a life span of 20-30 years.
② Other imported films, domestic pearlescent coated aluminum gusset plates, imported pearlescent coated aluminum gusset plates, LG pearlescent coated aluminum gusset plates (the service life and performance of coated aluminum gusset plates will be gradually improved).
③ Domestic membrane
Generally, the film thickness is between 0.1-0.3mm. Generally, the thickness of famous brands is between 0.1-0.2mm.. ..
The thicker the board, the wider the visual effect, but not the thicker the better. More than 0.6 mm is enough. Generally, the thickness of the coated board of well-known brands is about 0.7 mm The easiest way to judge the thickness is to pick it up and shake it to see if the board is tough. Some merchants say that their boards are thick, but they shake in an instant; Although the thickness of some boards is ok, a large proportion is the thickness of film covering. The thickness of the film can be observed from the cross section of the pinch plate. However, the accurate thickness has to be measured with calipers, and the visual or hand feel errors are very large.
3) Common specifications for home improvement
The main specifications are: 300 mm×300mm, 300 mm×600mm.
Roll coated plate:
Roller drawing board is made by degreasing and chemical treatment on the surface of aluminum substrate, roller coating with high quality paint, drying and curing. The base material is the same as the peritoneal plate. Through the high-performance roller coating process, the accuracy and flatness of the plate can be controlled more effectively, and the unevenness caused by tradition can be successfully eliminated, so that the architectural decoration color is uniform, delicate, soft and bright. According to the different coating and roller coating methods, the quality is also different. The film thickness on its surface is thinner than that of the coated board, only 0.04mm, so the conventional roll coated board is generally 0. 1mm thinner than the coated board of the same specification. However, due to the roll coating process, it is less prone to color difference than the film-coated board. Compared with the film-coated board, it is soft in reflection, easy to clean and not easy to scratch and change color, but the price is higher.
1) Main features of roller coating:
(1) the melting point of aluminum with good temperature resistance is 660 degrees, which can't be reached at room temperature.
(2) strong environmental protection, not easy to turn yellow, and chrome-free treatment solution is adopted to make up for the defect that the coated plate is easy to change color; Roller coating contains active chemical molecules to promote the formation of protective layer on the surface of materials. The active chemical molecules are stable and easy to recycle, which meets the requirements of environmental protection.
(3) Corrosion resistance, because there is a dense oxide film on its surface, which has the characteristics of strong adhesion, oxidation resistance, acid resistance, alkali resistance, corrosion resistance, corrosion resistance and ultraviolet radiation resistance.
(4) uniform and lasting color. Its color is uniform, delicate, soft and gorgeous, which avoids the individual color difference phenomenon of traditional spraying. No matter how big the ceiling is, its color is consistent and lasting.
⑤ Rigid-tough composite plate has extremely high strength, and can be cut, sliced, bent, pressed, drilled, connected and fixed, and compressed at the edge.
2) Common specifications of home decoration: 300mm× 300mm and 300mm× 600mm.
Oxide plate:
The manufacturing process of oxide plate is a unique anodic oxidation treatment, which is a revolutionary breakthrough to the old electrochemical bright treatment technology. It can effectively protect materials from erosion, antistatic, dust-free, easy to clean, fire-proof and excellent heat dissipation. The surface of anodic oxidation process never falls off, especially suitable for family use, and it is gradually becoming the new favorite of aluminum gusset plate industry in home decoration. High technical requirements and the highest price. Because the surface is fine, smooth and does not change color, it is the most resistant to cleaning among the three types.
(2) Construction technology: light steel keel is used as the skeleton and assembled on site. The material supplier provides free installation.
(3) Cost of a single flat: The current market price varies from 220 yuan to 260 yuan per flat.
3. Aluminum-plastic board
(1) material analysis: aluminum-plastic plate is made of aluminum and plastic, which is waterproof, fireproof and corrosion-resistant. It is a whole board with a length of 2.44m and a width of1.22 m. It can be used as a whole ceiling or can be cut at will according to your own needs, so it is more flexible when hanging some special-shaped roofs. Aluminum-plastic plate has the characteristics of beautiful appearance, durability, high strength, high temperature adaptability, good fire resistance, strong acid resistance, good sound insulation, easy maintenance, simple cleaning and so on. Its cost is lower than that of aluminum gusset plate and its decorative effect is good. It is a new type of interior and exterior wall decoration material that is not popular in recent years. At the same time, it is found that aluminum-plastic panels have been widely used in home decoration, and can also be used to cover doors, make door covers, window covers and so on. However, it is recommended to use it in a small area at home. If it is widely used, it will be too commercialized, unless, of course, it is used to decorate office buildings.
From the aesthetic point of view: if the ceiling area of kitchen and bathroom is small, use aluminum-plastic board, and it is better to use a unified block with a smaller area; If the ceiling is large (8, 9 flat or above), it will be more beautiful to use aluminum gusset plate, and the long straight line will look very atmospheric. If it is equal to the interception area of the floor tile and far away from the floor tile, it gives people a seamless feeling. The most feared thing with aluminum-plastic board is that the line above the ceiling is broken, and there must be no hidden dangers such as water leakage upstairs.
(2) Construction technology: Fix Jiuli board with 3*5 wood square grid frame or light steel keel frame, cut aluminum-plastic board into corresponding shapes, stick it with all-purpose glue, stick glass glue around the board edge, remove the protective film and move in.
(3) Single flat cost: wooden keel 25 yuan or light steel keel 40 yuan, Jiuliban 10 yuan aluminum-plastic panel 20 yuan Universal Glue, which are domestic joint ventures. The current market price of each piece (1.22*2.44=2.88 flat) varies from 60 yuan to 240 yuan. The construction cost is 40 yuan per square meter.
