Talking about ceiling knowledge

The decoration of the ceiling is the first work of the decoration project. From the process point of view, most colleagues will start with the construction of smallpox. But it is often ignored by users and most designers and engineering contractors. Ceiling (board), also known as ceiling or ceiling. This exercise is called "ceiling" or "suspended ceiling". The decoration materials of smallpox are the main basis for distinguishing the names of smallpox, mainly including: light steel keel gypsum board ceiling, gypsum board ceiling, plywood ceiling, irregular strip aluminum gusset ceiling, square painted aluminum gusset ceiling, colored glass ceiling, etc. If the ceiling adopts aluminum gusset plate, we usually call it "aluminum gusset plate ceiling". Here we look at the characteristics of various ceilings. 1, light steel keel gypsum board ceiling gypsum board is made of plaster of Paris as the main raw material, with additives and fibers, which has the properties of light weight, heat insulation, sound absorption, incombustibility and sawability. Gypsum board and light steel keel (pressed by galvanized steel sheet) are combined into light steel keel gypsum board. There are many types of light steel keel gypsum board ceiling, including paper gypsum board, decorative gypsum board, fiber gypsum board and hollow gypsum board strip. There are many specifications on the market. At present, as a partition wall, the light steel keel gypsum board ceiling is rarely used for ceiling modeling. 2. Square smallpox

Mostly used in commercial space, generally using 600x600 specifications, with obvious bones and hidden bones. Keels are usually made of aluminum or iron. Main board materials can be divided into gypsum board, calcium silicate board and mineral wool board. Gypsum has been explained in the previous paragraph. Let's talk about calcium silicate board and mineral wool board first. 1) The full name of calcium silicate board is fiber reinforced calcium silicate board, which is a lightweight board made of siliceous materials (diatomite, bentonite, quartz powder, etc.). ), calcareous materials, reinforced fibers, etc. As the main raw material, through pulping, briquetting, steam curing, surface sanding and other processes. Calcium silicate board is light in weight, high in strength, moisture-proof, anticorrosive and fireproof. Another notable feature is that it is easy to reprocess, unlike gypsum board, which is easy to powder and break. 2) Mineral wool board is made of slag through high temperature, high pressure, high-speed rotation, impurity removal and washing, and is mainly composed of mineral wool, adhesive, paper pulp and perlite. Mineral wool board and calcium silicate board have similar characteristics, but their sound absorption performance is better than gypsum board and calcium silicate board. 3. Plywood ceiling is commonly used in decoration at present. Plywood (also called plywood) is made by cooking and softening logs, cutting them into large pieces along the annual rings, drying, sorting, gluing, assembling blanks, hot pressing and sawing. It has the characteristics of light weight, high strength, good elasticity and toughness, and resistance to impact and vibration. Easy processing and finishing, heat preservation and the like. Smallpox usually uses a 5 cm splint. 3 mm is too thin and easy to arch, 9 mm is too thick. The reason why it is popular is that it can easily create various shapes of smallpox, including curved, round and square. Plywood ceiling may fall off after painting for a period of time. The method is to brush varnish (varnish) first when decorating, and then do other processes after drying thoroughly. The disadvantage of another splint is that the joints will crack. The solution is to fill the joints with putty when decorating. 4. Baked aluminum gusset ceiling aluminum gusset special-shaped materials are mainly divided into three types: strip, square and grid. Striped painted aluminum gusset ceiling is a kind of strip aluminum gusset, which is generally suitable for walkways and other places, and is helpful to weaken the sense of length in design. Most of the home improvement materials are no longer used, mainly because they are not resistant to dirt and are easily deformed. Square aluminum gusset plate is divided into two specifications: 300x300mm and 600x600mm. The former is suitable for dirty places such as kitchens and toilets, while the latter is often used in commercial places such as offices. It is the mainstream product at present. The square aluminum plate is the same as the long aluminum gusset plate.

Grid aluminum gusset plate is suitable for the decoration of commercial space, balcony and aisle. The specification is 100x 100 mm, and the square aluminum gusset plate has no pores. The main advantage of microporous aluminum gusset plate is that it can transmit moisture, so that the moisture in wet areas such as toilets can enter the top through pores, avoiding the formation of water droplets on the plate. The most important thing to buy an aluminum gusset plate is to check its aluminum thickness. Generally, the thickness of 300x300mm aluminum gusset plate needs 0.6mm, and that of 600x600mm aluminum gusset plate needs 0.8mm. Some unscrupulous merchants like to bully consumers by thickening the paint layer, which is worthy of attention. When buying aluminum gusset plates, you should also be careful that some people make fakes with stainless iron. To verify whether they are pure aluminum, impure aluminum or stainless iron, magnets can be used to verify that real aluminum does not attract magnetism, and inferior aluminum or fake aluminum can attract magnetism. But this method is not a complete solution, because unscrupulous merchants can also forge this feature by degaussing. 6. Colored glass ceiling Colored glass is painted directly on the glass with pigments, and then the barbecue is completed, and then the lighting is used to reflect the beauty of color. Its various patterns can be used for interior lighting. But this material is only used for local decoration, otherwise it will be like a Christian church. The decoration of suspended ceiling, in addition to material selection, is mainly the problem of shape and size ratio. The former should be handled according to the specific situation, while the latter should be calculated with ergonomics and aesthetics as examples. In terms of height, the indoor clear height of home decoration should not be less than 2.5 meters. Otherwise, try not to do modeling smallpox, and choose gypsum wireframe decoration. If light steel keel gypsum board ceiling or plywood ceiling is used for decoration, it will be used for

When its surface is colored. The joints should be sealed with gypsum powder first, and then sealed with sealing tape before priming and painting. Ceiling construction, no matter what kind of material, we must remember one thing: sealing! In case mice and cockroaches nest in it.
