一、沖孔鋁板有哪些孔型

沖孔鋁(lv)單板不(bu)僅防(fang)塵防(fang)潮、防(fang)火阻燃、耐磨耐候、使用壽命長，而且具(ju)有很(hen)好的(de)可塑性，能(neng)實現許多驚(jing)艷的(de)鏤空造(zao)型創意裝飾，深受(shou)人們喜(xi)愛。

沖孔(kong)(kong)鋁板有(you)多種不同的(de)(de)孔(kong)(kong)型，常見(jian)(jian)的(de)(de)有(you)圓孔(kong)(kong)、方孔(kong)(kong)、長(chang)圓孔(kong)(kong)、六(liu)邊形(xing)孔(kong)(kong)、魚鱗孔(kong)(kong)等，常見(jian)(jian)的(de)(de)排(pai)列(lie)方式(shi)有(you)直排(pai)和錯排(pai)。還可以根據需(xu)要定(ding)制其(qi)他孔(kong)(kong)型的(de)(de)沖孔(kong)(kong)鋁單(dan)板。

二、沖孔鋁單板的孔徑是多少

沖(chong)孔(kong)鋁(lv)單(dan)板(ban)(ban)的孔(kong)徑(jing)是指鋁(lv)單(dan)板(ban)(ban)上沖(chong)出來的孔(kong)的直徑(jing)，一(yi)般規(gui)則(ze)沖(chong)孔(kong)鋁(lv)單(dan)板(ban)(ban)的孔(kong)徑(jing)、孔(kong)距大小一(yi)致，不規(gui)則(ze)沖(chong)孔(kong)鋁(lv)單(dan)板(ban)(ban)（藝術沖(chong)孔(kong)鋁(lv)單(dan)板(ban)(ban)），其孔(kong)徑(jing)、孔(kong)距大小不一(yi)致。

規則沖孔(kong)鋁(lv)單板(ban)(ban)的(de)(de)孔(kong)徑一般有(you)3mm、4mm、5mm、6mm等多種(zhong)，理(li)論上(shang)來說，沖孔(kong)鋁(lv)單板(ban)(ban)的(de)(de)孔(kong)徑也與其厚度(du)有(you)關，1.0毫(hao)(hao)米鋁(lv)板(ban)(ban)不能小于板(ban)(ban)的(de)(de)厚度(du)，1毫(hao)(hao)米鋁(lv)板(ban)(ban)要(yao)沖孔(kong)1.0毫(hao)(hao)米以上(shang)。

三、開孔鋁單板的沖孔率怎么算

開孔(kong)(kong)(kong)(kong)(kong)鋁(lv)單板的沖(chong)孔(kong)(kong)(kong)(kong)(kong)率(lv)是指(zhi)的沖(chong)孔(kong)(kong)(kong)(kong)(kong)密度(du)，一(yi)般通過(guo)公式可以計算出來，計算公式是：沖(chong)孔(kong)(kong)(kong)(kong)(kong)率(lv)=沖(chong)孔(kong)(kong)(kong)(kong)(kong)面(mian)積(ji)/整塊(kuai)沖(chong)孔(kong)(kong)(kong)(kong)(kong)鋁(lv)板面(mian)積(ji)，孔(kong)(kong)(kong)(kong)(kong)徑與孔(kong)(kong)(kong)(kong)(kong)距，共同決定了沖(chong)孔(kong)(kong)(kong)(kong)(kong)鋁(lv)單板的沖(chong)孔(kong)(kong)(kong)(kong)(kong)率(lv)。

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%。

沖孔率較(jiao)大(da)時(shi)，還要考慮鋁(lv)板的強度和(he)抗(kang)變(bian)形能力(li)，尤其(qi)是應用于(yu)室外幕墻(qiang)工程(cheng)時(shi)。比如沖孔率大(da)于(yu)50%時(shi)，為(wei)了(le)保證板面的平整度與(yu)效果(guo)，不能用小于(yu)3.0mm厚的鋁(lv)板。
