What are the common ceiling materials?

Ceiling materials include: mineral wool board and calcium silicate board. 1. Gypsum board: It is made of building gypsum as the main raw material. It has excellent properties such as light weight, high strength, thin thickness, convenient processing, sound insulation and fire prevention. Gypsum board is one of the most widely used new lightweight boards in modern decoration. 2, mineral wool board: made of mineral fiber cotton as raw materials, the biggest feature is that it has good sound absorption and heat insulation effect, and is often used for ceiling decoration with high temperature and sound insulation, such as kitchen. The surface of mineral wool board can also be painted and engraved with patterns, and there are more choices in styles.

Ceiling type:

1, light steel keel plasterboard ceiling

Gypsum board is made of gypsum ash as the main raw material, with additives and fibers. It has the properties of light weight, heat insulation, sound absorption, incombustibility and sawability. Gypsum board and light steel keel are combined to form light steel keel gypsum board ceiling. There are many kinds, including paper gypsum board and hollow gypsum board, and there are many specifications on the market. At present, the light steel keel gypsum board ceiling is used as a partition wall, and less as a modeling ceiling.

2, Fang Kuai smallpox

Mostly used in commercial space, generally 600mm×600mm specifications, with open 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 board has been explained in the previous paragraph. This is calcium silicate board and mineral wool board.

(1) calcium silicate board. The full name of fiber reinforced calcium silicate board is a lightweight board made of siliceous materials, calcareous materials and reinforced fibers through pulping, blank forming, steam curing and surface sanding. Calcium silicate board has the advantages of light weight, high strength, moisture resistance, corrosion resistance and fire prevention. Another notable feature is that it is easy to reprocess, unlike gypsum board, which is easily broken into powder.

② Mineral wool board. Slag rotates at high temperature, high pressure and high speed to remove impurities and wash into mineral wool. Mineral wool bonding consists of mineral wool, adhesive, 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 smallpox

At present, plywood ceiling is widely used in decoration. Plywood is made by cooking and softening logs, cutting them into large pieces along annual rings, drying, sorting, gluing, assembling blanks, hot pressing and trimming. It has the advantages of light material, high strength, good elasticity and toughness, impact and vibration resistance, easy processing, coating and insulation. Generally, a 5mm splint is used for smallpox. 3mm splint is too thin and easy to arch, and 9mm splint is too thick. The reason why it is popular is that it is easy to create smallpox in various shapes, including curved, round and square. Plywood smallpox may lose paint in a period of time. The method is to paint varnish first when decorating, and then do other processes after drying. The disadvantage of another splint is that the joints will crack. The solution is to fill the joints with putty when decorating.

4. Paint the aluminum gusset ceiling

The special-shaped materials of aluminum gusset plate are mainly divided into three types: strip, square and grid.

(1) Striped painted aluminum gusset ceiling is a strip aluminum gusset, which is generally suitable for walkways and other places, and is helpful to weaken the sense of length and width in design. This material is no longer used in home decoration, mainly because it is not resistant to dirt and is easy to deform.

(2) Square joint plates are divided into 300mm×300mm and 600 mm× 600 mm The former is suitable for dirty places such as kitchens and bathrooms, and the latter is often used in commercial places such as offices. Square aluminum gusset plate is an expanded product at present. Square aluminum gusset plates can be divided into microporous and non-microporous types. 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.

(3) The grid aluminum gusset plate is suitable for the decoration of commercial spaces, balconies and corridors, and the specification is100 mm×100 mm..

The most important thing to buy an aluminum gusset plate is to check its aluminum thickness. Generally, the thickness of 300mm×300mm aluminum gusset plate needs 0.6mm, and the thickness of 600mm×600mm aluminum gusset plate needs 0.8 mm. Some unscrupulous merchants like to bully consumers by thickening the paint layer to increase the overall thickness, which is worth noting.

When buying aluminum gusset plates, you should also be careful that some people pretend to be stainless steel. To verify whether it is pure aluminum or impure aluminum or stainless iron, you can use magnets 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.

⑤ Painted glass ceiling

Painted glass is to apply pigment directly on the glass, and then barbecue, and reflect the beauty of color through lighting. It has a variety of patterns and can be used for interior lighting. But this material is only used for local decoration, otherwise it will be like a church.
