The classification and usage of aluminum veneer

Aluminum veneer, just as its name implies is made of aluminum or aluminum alloy material plate type materials.Or by extending to straighten, heating, rolling flat aluminum embryo or solid solution aging heat process and plate type aluminum products.Available to a variety of color of the surface of the spraying, good strength, low cost, long life, if direct contact with steel, aluminum veneer hanging on the wall, 50 years will not fall off and corrosion (before liberation in tianjin made of aluminum veneer roof still intact).
Building on the use of aluminum sheet including single aluminum sheet, aluminum veneer and various composite materials, general often refers to the single aluminum sheet (also called single aluminum sheet or pure aluminum veneer), used in building decoration engineering, in recent years in the aluminum panel curtain wall single-layer aluminum veneer use is relatively rare.Anodic oxidation of oxide film, generally in more than 12 mu, color only two bronze and white, color monotone, more serious disadvantage is that the color shades of each aluminum veneer board face, many pieces of curtain wall plate combined together to form a wall of the overall effect is very ugly.
Spraying is divided into powder coating and liquid coating.Reinforced with LF21 aluminum belt, according to the width of the ribbon thickness aluminum veneer panels, generally 2-2.5 mm thick, 10 to 25 mm wide.So the aluminum panel curtain wall aluminum veneer surface treatment, can not use anodic oxidation.Why aluminum veneer curtain wall aluminum veneer on the back of the stiffener, is in the outside world under the condition of positive and negative pressure, aluminum veneer not sag, the second not bulging, thus avoiding the aluminum panel curtain wall inside and vibration and the vibration of the sound again and again.
Single integral stamping aluminum sheet is made of single-layer aluminum veneer special processing, in line with building exteriors plastic and use of special shape aluminum veneer metope, can see it as a single aluminum sheet is a kind of special feeling.In our country in order to reduce weight aluminum veneer, increase the strength of aluminum veneer, we adopt aluminum alloy plate, often choose 21 antirust code LF21 aluminum pressed into the aluminum veneer curtain wall aluminum veneer.
Because of the single aluminum sheet is cellular aluminum veneer is easier to bend processing and forming complex shapes, better able to adapt to change endless demand for building exterior wall decoration, it is generally believed single aluminum sheet for aluminum sheet curtain wall material is the best.Liquid spray paint spray or fluorocarbon polymer coating, commonly known as fluorinated carbon spray coating, is used to make paint fluorocarbon polymer resin, metal finish, and the combination of the fluorine is the most stable molecules.Owing to the aluminum sheet is not a batch number, chemical composition have little difference, plus the oxidation liquid electrolytic cell factors such as current density are not exactly the same, so the color of the oxidized how much all have differences, single see may not be obvious, if is together is very obvious.The spraying powder, touch friction resistance, resistant to 50 kg impact, aluminum veneer of shape, spray coating without crack, without layer intact, resistance to dilute acid and mortar.

Aluminum veneer thickness from 3 mm reduced to 2.5 mm, the intensity of the alloy is more than double that of pure aluminum veneer.Aluminum veneer thickness is 3 mm, in order to strengthen the strength of aluminum veneer board face, in the back of the aluminum sheet, must be installed reinforcement (existing) manufacturers, the reinforced with thick aluminum belt.Each nut with flash welder welding first then put on the back of aluminum veneer for reinforcement of aluminum strip into drilling screw, screw fixation.Single-layer aluminum veneer generally in pure aluminum veneer.Many domestic manufacturers of spraying powder, the weight difference is very big, some powder containing gold scrap this powder after on metope, along with the changes in the Angle of sunlight, day and evening have change, metope color depth are different, choose powder spray coating and attract attention.
Single aluminum sheet curtain wall, it is to use 3 mm or pure aluminum LF212.5 mm aluminum veneer veneer do curtain wall plate, single aluminum sheet is for stud welding technology is developing with the development of the stud welding implements the reinforcement on the underside of the single-layer aluminum veneer decorative surface welding stiffener, and does not destroy the aluminum veneer veneer, single-layer aluminum veneer easy bending processing into complex shapes, high strength long life (up to 50 years), thus it makes the aluminum panel curtain wall are all rich in processing form and installation structure form.
Aluminum curtain wall veneer surface treatment, can be divided into two methods: one is anodic oxidation, another kind is electrostatic spraying.The only downside is afraid of long-term exposure to the sun's ultraviolet rays, easy generation of Yin and Yang face color difference after a few years.Life may be longer and building life match.If you need to sound insulation heat preservation, can be in aluminum veneer inside, rock wool, cotton or foaming slag treatment was laid.Powder coating materials are mainly: expansion and resin, polyurethane, epoxy resin, such as raw material with high colour pigments, dozens of different colors of spraying powder can be obtained.Aluminum sheet curtain wall is also a form of curtain wall, simply replace glass with aluminum sheet curtain wall, aluminum veneer curtain wall used to make the wall more sheltered and not the wall of the daylighting, foreign aluminum veneer curtain wall has been chosen single-layer aluminum veneer.
