铝卷板及铝平板的平分秋色

来源:

建筑上使用的铝板包括单层铝板、复合铝板等多种材料,一般常常指单层铝板(也有叫单铝板或纯铝板),多用于建筑装饰工程中,近年来在铝板幕墙中单层铝板使用的较为多见。铝板幕墙也是幕墙的一种形式,简单地说是用铝板代替玻璃制成幕墙,铝板幕墙多用于作墙体蔽护和不采光的墙壁。
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.
国外的铝板幕墙一直选用单层铝板。单层铝板一般用纯铝板。铝板厚度为3mm,为了加强铝板板面强度,在铝板的背面,必须安装加强筋(现有的厂家不安),加强筋用厚的铝带做成,先用闪光焊机把一颗颗螺丝帽焊在铝板背面然后把作加强筋的铝条钻孔套进螺丝内,用螺丝固定。
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.

我国为了减轻铝板重量,增加铝板强度,大家采用铝合金板,常选用21号防锈铝代号LF21压成的铝板作幕墙铝板。铝板厚度由原来3mm减少为2.5mm,该合金强度比纯铝板高出一倍左右。加强筋用LF21铝带,铝带的宽度厚度根据铝板板面而定,一般厚2-2.5mm,宽10-25mm。铝板幕墙的铝板背面为什么要安加强筋,是在外界正负压力的情况下,铝板一不会凹陷,二不会鼓出,这样就避免了铝板幕墙反复里外振动而发出的振动声音。如果需要隔音保温,可在铝板内侧,安顿岩棉、矿渣棉或发泡处理。
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.
幕墙铝板表面处理,可分为二种方法,一种是阳极氧化,另一种是静电喷涂。阳极氧化的氧化膜一般在12μ以上,颜色只有古铜色和白色两种,颜色单调,更为严重的缺点是每块铝板板面的颜色深浅不一,许多块幕墙板组合在一起形成一个幕墙整体效果非常难看。这个缺点可以说无法消除,并非生产技术造成的,而是由于铝板并非是由一批号,化学成份,均有小的差别,再加上氧化时电解槽液电流密度等因素均无法完全一样,所以氧化后的颜色多少均有差异,单张看可能不明显,若都排在一起即非常明显。所以铝板幕墙的铝板表面处理,决不能用阳极氧化。
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.
幕墙铝板表面处理的另一种方法是静电喷涂。喷涂又分为粉沫喷涂和液体喷涂。粉沫喷涂材料主要为:聚氨酯、聚胀树脂、环氧树脂等原料配以高保色性颜料,可得到几十种不同颜色的喷涂粉沫。该喷涂粉沫,耐撞碰耐磨擦,在50公斤撞击下,铝板变形,喷涂层无裂纹,无掉层完整无损,抗稀酸及砂浆。的缺点怕紫外线长期照射,几年后易产生阴阳面颜色的差异。国内不少厂家生产的喷涂粉沫,重量差异甚大,有的粉沫含金屑这种粉沫在挂到墙面以后,随阳光角度变化,白天和黄昏有变化,墙面颜色深浅有差异,选用粉沫喷涂料希引起注意。
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.
