In modern design, the entrance is often quoted by the designer into the home decoration, and its appearance makes our home decoration diversified. The porch design is part of the home design, so its style should be in harmony with the whole indoor environment, and the entrance is largely a microcosm of the interior style.
1, aluminum honeycomb perforated sound absorbing board porch ceiling
The structure is a perforated panel and a perforated backboard, and is directly bonded to an aluminum honeycomb sandwich structure by a high-quality adhesive and an aluminum honeycomb core, and a sound absorbing cloth is attached between the honeycomb core and the panel and the backboard. Since the honeycomb core in the honeycomb aluminum plate is divided into a plurality of closed cells, the air flow is prevented, the sound waves are hindered, the sound absorption coefficient is increased (up to 0.9 or more), and the strength of the plate itself is improved, so that the size of the single plate can be To achieve greater, further increase the freedom of design. According to the indoor acoustic design, different perforation rate design can be carried out to control the sound absorption coefficient of the combined structure within a certain range, which not only achieves the design effect, but also can reasonably control the cost.
By controlling the perforation aperture and hole spacing, and changing the perforation rate according to the customer's requirements, the maximum perforation rate is <30%. The aperture is generally selected from the specifications of ∮2.0, ∮2.5, ∮3.0, etc. The back plate perforation requirements are the same as the panel, and the sound absorbing cloth is adopted. Sound-absorbing materials such as high-quality non-woven fabrics. It is suitable for the sound-absorbing wall panels and ceiling panels of large public buildings such as subways, theaters, radio stations, TV stations, textile factories and super-standard buildings.
Features:
(1) Large plate surface and high flatness
(2) High strength and light weight
(3) Good sound absorption, fireproof and waterproof
(4) Easy to install, each board can be disassembled and replaced separately
(5) It can be customized according to customer's requirements in terms of size, shape, surface treatment and color to meet the individual needs of customers.
5, shaped long strip aluminum buckle board porch ceiling
Most of the home decoration has no longer used this material, mainly because it is not resistant to dirt and is easily deformed.
6, square painted aluminum buckle board porch ceiling
Use in places that are easily soiled, such as kitchens and toilets. It is the current mainstream product.
7, stained glass porch ceiling
A variety of patterns, can be illuminated. Only for local use.
8, metal grid porch ceiling
Most of the aisles or rooms used in commercial spaces feel modern.
2, gypsum board porch ceiling
It is mostly used in commercial space. It is generally used in 600x600 (mm, the length of the unit is not indicated in the project, and its unit is mm). It has the distinction of bright bone and dark bone. The keel is usually made of aluminum or iron.
3, plywood porch ceiling
It is commonly used for current decoration. The splint (also called plywood) is made by cutting and softening the logs, and then cutting them into large sheets along the annual rings, which are formed by drying, finishing, coating, forming, hot pressing and sawing. Lightweight, high strength, good elasticity and toughness, impact resistance and vibration. Easy processing and finishing, insulation and other advantages. For smallpox, use a 5 PCT splint. 3 PCT is too thin to arch, 9 PCT is too thick. The reason for its popularity is that it can easily create a wide variety of styling ceilings, including curved, round, and square. But there is a disadvantage: afraid of termites. The remedy is to spray anti-termite potion. Splint ceilings may take some time to use paint. The method is to first brush the varnish (varnish) before the decoration, and then do another process. Another disadvantage of the splint is that the interface will crack, by using the atomic ash to fill the interface during the renovation.
4, light steel keel gypsum board porch ceiling
Gypsum board is made of calcined gypsum as the main raw material and mixed with additives and fibers. It has the properties of light weight, heat insulation, sound absorption, non-combustibility and sawability. The gypsum board is combined with a light steel keel (pressed from galvanized steel) to form a light steel keel gypsum board. Light steel keel gypsum board ceilings are available in a variety of types, including plasterboard, decorative plasterboard, fiber plasterboard, and hollow plasterboard. There are many specifications on the market. At present, the use of light steel keel gypsum board ceiling as a partition wall is used to make small ceilings.
