鋁卷板及鋁平板的平分秋色

來源:http://www.wangzhuanquan.cn/ 發布時間:2018-11-02

建筑上使用的鋁板包括單層鋁板、復合鋁板等多種材料,一般常常指單層鋁板(也有叫單鋁板或純鋁板),多用于建筑裝飾工程中,近年來在鋁板幕墻中單層鋁板使用的較為多見。鋁板幕墻也是幕墻的一種形式,簡單地說是用鋁板代替玻璃制成幕墻,鋁板幕墻多用于作墻體蔽護和不采光的墻壁。
Aluminum sheets used in buildings include single-layer aluminium sheets, composite aluminium sheets and other materials, usually referring to single-layer aluminium sheets (also known as single-layer aluminium sheets or pure aluminium sheets), which are mostly used in architectural decoration projects. In recent years, single-layer aluminium sheets are commonly used in aluminium sheet curtain walls. Aluminum plate curtain wall is also a form of curtain wall. Simply speaking, it is made of aluminum plate instead of glass. Aluminum plate curtain wall is mostly used as wall shelter and wall without lighting.
國外的鋁板幕墻一直選用單層鋁板。單層鋁板一般用純鋁板。鋁板厚度為3mm,為了加強鋁板板面強度,在鋁板的背面,必須安裝加強筋(現有的廠家不安),加強筋用厚的鋁帶做成,先用閃光焊機把一顆顆螺絲帽焊在鋁板背面然后把作加強筋的鋁條鉆孔套進螺絲內,用螺絲固定。
The aluminum sheet curtain walls abroad have been selected for single layer aluminum plates. Single layer aluminum plates are usually made of pure aluminum plates. The thickness of aluminium sheet is 3 mm. In order to strengthen the strength of aluminium sheet, reinforcement bars must be installed on the back of the aluminium sheet (the existing manufacturers are uneasy). The reinforcement bars are made of thick aluminium strips. First, a screw cap is welded on the back of the aluminium sheet by flash welding machine, and then the aluminium bars drilled as reinforcement bars are inserted into the screw and fixed by the screw.

我國為了減輕鋁板重量,增加鋁板強度,我們采用鋁合金板,常選用21號防銹鋁代號LF21壓成的鋁板作幕墻鋁板。鋁板厚度由原來3mm減少為2.5mm,該合金強度比純鋁板高出一倍左右。加強筋用LF21鋁帶,鋁帶的寬度厚度根據鋁板板面而定,一般厚2-2.5mm,寬10-25mm。鋁板幕墻的鋁板背面為什么要安加強筋,是在外界正負壓力的情況下,鋁板一不會凹陷,二不會鼓出,這樣就避免了鋁板幕墻反復里外振動而發出的振動聲音。如果需要隔音保溫,可在鋁板內側,安放巖棉、礦渣棉或發泡處理。
In order to reduce the weight of aluminium sheet and increase the strength of aluminium sheet, aluminium sheet is used in our country. Aluminum sheet pressed by No. 21 anti-rust aluminium code LF21 is often used as curtain wall aluminium sheet. The thickness of aluminum plate is reduced from 3mm to 2.5mm, which is twice as high as that of pure aluminum sheet. LF21 aluminium strip is used for reinforcing bars. The width and thickness of the strip depend on the surface of the aluminium plate. Generally, the thickness is 2-2.5mm and the width is 10-25mm. The reason why reinforcement should be installed on the back of aluminium plate curtain wall is that under positive and negative external pressure, the aluminium plate will not sink or bulge out, thus avoiding the vibration sound caused by repeated internal and external vibration of aluminium plate curtain wall. If sound insulation is needed, the rock can be placed on the inside of the aluminum sheet, with rock wool, slag wool or foam treatment.
幕墻鋁板表面處理,可分為二種方法,一種是陽極氧化,另一種是靜電噴涂。陽極氧化的氧化膜一般在12μ以上,顏色只有古銅色和白色兩種,顏色單調,更為嚴重的缺點是每塊鋁板板面的顏色深淺不一,許多塊幕墻板組合在一起形成一個幕墻整體效果非常難看。這個缺點可以說無法消除,并非生產技術造成的,而是由于鋁板并非是由一批號,化學成份,均有小的差別,再加上氧化時電解槽液電流密度等因素均無法完全一樣,所以氧化后的顏色多少均有差異,單張看可能不明顯,若都排在一起即非常明顯。所以鋁板幕墻的鋁板表面處理,決不能用陽極氧化。
Surface treatment of aluminium curtain wall can be divided into two methods, one is anodic oxidation, the other is electrostatic spraying. Anodized oxide film is generally more than 12 mu. The color is only bronze and white. The color is monotonous. The more serious disadvantage is that the color of each aluminium panel is different. Many curtain panels are combined to form a curtain wall with a very ugly overall effect. This disadvantage can not be eliminated, not caused by production technology, but because the aluminium plate is not a batch number, chemical composition, there are small differences, coupled with the oxidation of electrolyte current density and other factors can not be exactly the same, so the number of color after oxidation is different, single sheet may not be obvious, if all. That is very obvious. Therefore, the surface treatment of aluminum plate curtain wall must not be anodized.
幕墻鋁板表面處理的另一種方法是靜電噴涂。噴涂又分為粉沫噴涂和液體噴涂。粉沫噴涂材料主要為:聚氨酯、聚脹樹脂、環氧樹脂等原料配以高保色性顏料,可得到幾十種不同顏色的噴涂粉沫。該噴涂粉沫,耐撞碰耐磨擦,在50公斤撞擊下,鋁板變形,噴涂層無裂紋,無掉層完整無損,抗稀酸及砂漿。的缺點怕紫外線長期照射,幾年后易產生陰陽面顏色的差異。國內不少廠家生產的噴涂粉沫,重量差異甚大,有的粉沫含金屑這種粉沫在掛到墻面以后,隨陽光角度變化,白天和黃昏有變化,墻面顏色深淺有差異,選用粉沫噴涂料希引起注意。
Another way of surface treatment of aluminum curtain wall is electrostatic spraying. Spraying is divided into powder spray and liquid spray. Powder spraying materials are mainly polyurethane, swelling resin, epoxy resin and other raw materials with high color retention pigments, dozens of different color spraying powder can be obtained. The spraying powder, impact resistance and abrasion resistance, under the impact of 50 kg, the aluminum plate deformation, spraying coating without cracks, no layer dropping intact and non-destructive, anti-dilute acid and mortar. The only shortcoming is that the long term exposure to ultraviolet radiation will lead to differences in color between yin and Yang after a few years. The spraying powder produced by many domestic manufacturers has a great difference in weight. Some of them contain gold dust. After hanging on the wall, the powder changes with the angle of sunshine during the day and at dusk, and the color of the wall is different. The choice of powder spraying paint is expected to attract attention.
