The family of metal curtain wall is very large, the commonly used material mainly has the following kinds:
1. Aluminum-plastic composite board
Oglan Art fluorocarbon aluminum plastic board is composed of environmental protection low density polyethylene between two layers of aluminum board inside and outside, the board is coated with fluorocarbon resin coating, forming a tough, stable film layer, adhesion and durability is very strong, colorful, waterproof, moisture-proof insect resistant, weather resistant and not deformation of powerful functions. Oglan Art fluorocarbon aluminum panels are wall architects’ favorite material for metal facade panels.
2. Aluminum veneer
2.5mm or 3mm thick aluminum alloy plate is adopted. The surface of single-layer aluminum plate for external curtain wall is consistent with the coating material on the front of aluminum composite plate. The toughness, stability, adhesion and durability of the film layer are completely consistent.
3. Honeycomb aluminum plate
It is a kind of composite material bonded by two aluminum plates with honeycomb core materials. Thickness can be selected according to the use function and durability of curtain wall.
Honeycomb shape is hexagonal, flat hexagonal, rectangular, square, cross, flat square, etc., honeycomb core material to be special treatment, otherwise its strength is low, short life, such as chemical oxygen on aluminum foil, its strength and corrosion resistance will be increased. Besides aluminum foil, there are fiberglass honeycomb and paper honeycomb, but not many of them are used in practice. Because the cost of honeycomb aluminum plate is very high, so the consumption is not large.
4, fire board
It is a fireproof sandwich sandwich panel composed of metal plate (aluminum plate, stainless steel plate, colored steel plate, titanium zinc plate, titanium plate, copper plate, etc.) as the panel, halogen-free, flame-retardant and inorganic modified-material as the core layer, and hot-pressing composite. According to GB8624-2006, it is divided into two combustion performance grades: A2 and B.
5, metal sandwich fireproof board
Oglan high flame retardant aluminum plastic plate is A typical metal sandwich fire board, but also strict A, B level to choose. It not only has the function of fire prevention, but also maintains the mechanical property of the corresponding metal plastic composite board. It can be used as the exterior wall, interior wall decoration materials and indoor suspended ceiling of new buildings and renovated old buildings, especially suitable for some large public buildings with large personnel density and higher requirements on fire performance, such as conference center, exhibition hall, gymnasium, theater, etc.
6, titanium zinc plastic aluminum composite board
Really did panel, titanium zinc alloy plate 3003 h26 (H24) aluminum plate back, high pressure low density polyethylene (LDPE) as the core material, compounded by the heat of a new type of high-grade aluminum building materials, it combines the characteristics of titanium zinc plate (metal texture, surface repair function, long service life, good plasticity, etc.) and compound plate is flat and level, the advantage of high flexural performance at an organic whole, is a model of classical art and modern technology combine.
7. Sandwich insulation aluminum plate
It is similar to aluminum honeycomb board and aluminum composite board in form, except that the intermediate core layer material is different. The sandwich insulation aluminum board core layer is made of insulation material (rock wool, etc.). Because the price of sandwich aluminum insulation board is very high, and other aluminum insulation materials can also achieve the same insulation effect as sandwich aluminum insulation board, so the current sandwich aluminum insulation board consumption is not large.
8. Stainless steel plate
Mirror stainless steel plate, matte stainless steel plate, titanium plate, etc. Stainless steel plate durability, wear resistance is very good, but too thin board will bulge, too thick weight and price is very high, so the use of stainless steel plate curtain wall is not much, just in the local decoration of the curtain wall is playing a bigger role.
9. Painted steel plate
It is a kind of steel plate with organic coating, with good corrosion resistance, bright color, beautiful appearance, convenient processing and molding with the original strength of steel plate and other advantages of low cost. Color coated steel plate is widely used in the construction of home appliances and transportation and other industries, for the construction industry is mainly used in steel structure workshops, airports, warehouses and refrigeration and other industrial and commercial buildings roof walls and doors, civil buildings use less color steel plate.
10. Enamel steel plate
Its base material thickness is 1.6mm of very low carbon steel plate (carbon content is 0.004, general steel carbon content is 0.060), its root enamel layer glaze expansion coefficient is close to, after firing will not produce expansion stress caused by warping and bulging phenomenon, but also improve the adhesion strength of enamel and steel plate. Enamel steel plate with the strength of steel plate and vitreous smooth and hard, but without the brittleness of vitreous, vitreous mixture can be adjusted to make all kinds of colors, patterns.
At present, the quality inspection standard of enameled steel plate and enameled steel plate as the construction specification and acceptance standard of cladding material have not been issued yet.
Therefore, enameled steel plate is rarely used in construction.
