一、沖孔鋁板有哪些孔型

沖孔鋁(lv)單板(ban)不僅防(fang)塵防(fang)潮、防(fang)火(huo)阻燃、耐磨耐候、使(shi)用壽(shou)命長，而且具有很好的可塑性(xing)，能(neng)實現許多驚艷的鏤空造型(xing)創意裝(zhuang)飾，深受(shou)人們喜愛。

沖孔(kong)(kong)鋁板有(you)多(duo)種不(bu)同的孔(kong)(kong)型，常見(jian)的有(you)圓孔(kong)(kong)、方孔(kong)(kong)、長圓孔(kong)(kong)、六邊形孔(kong)(kong)、魚(yu)鱗孔(kong)(kong)等(deng)，常見(jian)的排列方式(shi)有(you)直排和(he)錯排。還可(ke)以根(gen)據需要定制(zhi)其他孔(kong)(kong)型的沖孔(kong)(kong)鋁單板。

二、沖孔鋁單板的孔徑是多少

沖(chong)(chong)孔(kong)(kong)鋁(lv)單(dan)板(ban)(ban)的孔(kong)(kong)徑是指鋁(lv)單(dan)板(ban)(ban)上(shang)沖(chong)(chong)出來的孔(kong)(kong)的直(zhi)徑，一(yi)般規(gui)則沖(chong)(chong)孔(kong)(kong)鋁(lv)單(dan)板(ban)(ban)的孔(kong)(kong)徑、孔(kong)(kong)距(ju)(ju)大小一(yi)致，不(bu)規(gui)則沖(chong)(chong)孔(kong)(kong)鋁(lv)單(dan)板(ban)(ban)（藝術沖(chong)(chong)孔(kong)(kong)鋁(lv)單(dan)板(ban)(ban)），其孔(kong)(kong)徑、孔(kong)(kong)距(ju)(ju)大小不(bu)一(yi)致。

規(gui)則沖孔鋁(lv)單(dan)板(ban)的(de)孔徑一般(ban)有3mm、4mm、5mm、6mm等多種，理論上(shang)來說，沖孔鋁(lv)單(dan)板(ban)的(de)孔徑也與其厚(hou)度有關，1.0毫米(mi)鋁(lv)板(ban)不能小于板(ban)的(de)厚(hou)度，1毫米(mi)鋁(lv)板(ban)要沖孔1.0毫米(mi)以上(shang)。

三、開孔鋁單板的沖孔率怎么算

開(kai)孔(kong)(kong)(kong)(kong)(kong)鋁單板的沖(chong)孔(kong)(kong)(kong)(kong)(kong)率是指的沖(chong)孔(kong)(kong)(kong)(kong)(kong)密(mi)度，一般通(tong)過公式可以計算出(chu)來，計算公式是：沖(chong)孔(kong)(kong)(kong)(kong)(kong)率=沖(chong)孔(kong)(kong)(kong)(kong)(kong)面(mian)積/整塊(kuai)沖(chong)孔(kong)(kong)(kong)(kong)(kong)鋁板面(mian)積，孔(kong)(kong)(kong)(kong)(kong)徑與(yu)孔(kong)(kong)(kong)(kong)(kong)距，共同決定了沖(chong)孔(kong)(kong)(kong)(kong)(kong)鋁單板的沖(chong)孔(kong)(kong)(kong)(kong)(kong)率。

沖孔鋁單板的沖孔率對鋁單板的沖孔質量有著至關重要的影響，一般要根據使用領域來選擇合適沖孔率的產品：一般來說，幕墻及天花吊頂裝飾用的沖孔鋁單板，沖孔率在15%—35%為佳，比較具美感與吸音功能；而外墻裝飾沖孔鋁單板的沖孔率，則可達50%。

沖(chong)孔率較大(da)(da)時，還要考(kao)慮鋁(lv)板的強(qiang)度和抗變形能(neng)力，尤其是應用于(yu)室外幕墻工程(cheng)時。比如沖(chong)孔率大(da)(da)于(yu)50%時，為了保證板面的平(ping)整度與效果，不(bu)能(neng)用小(xiao)于(yu)3.0mm厚的鋁(lv)板。
