一、沖孔鋁板有哪些孔型

沖(chong)孔(kong)鋁單板不僅防(fang)塵防(fang)潮、防(fang)火阻燃(ran)、耐磨耐候、使(shi)用壽命(ming)長，而且具有很好的可塑性，能實現許(xu)多驚艷(yan)的鏤(lou)空造型創意裝飾，深(shen)受人們喜(xi)愛。

沖(chong)孔(kong)(kong)鋁(lv)板有多種不同(tong)的孔(kong)(kong)型，常(chang)見(jian)的有圓孔(kong)(kong)、方(fang)(fang)孔(kong)(kong)、長圓孔(kong)(kong)、六(liu)邊形孔(kong)(kong)、魚鱗(lin)孔(kong)(kong)等(deng)，常(chang)見(jian)的排(pai)列方(fang)(fang)式有直排(pai)和錯排(pai)。還可以根據(ju)需要(yao)定制其(qi)他孔(kong)(kong)型的沖(chong)孔(kong)(kong)鋁(lv)單板。

二、沖孔鋁單板的孔徑是多少

沖(chong)(chong)(chong)孔(kong)(kong)(kong)鋁(lv)單板(ban)的(de)孔(kong)(kong)(kong)徑是(shi)指鋁(lv)單板(ban)上沖(chong)(chong)(chong)出來的(de)孔(kong)(kong)(kong)的(de)直徑，一般規則(ze)沖(chong)(chong)(chong)孔(kong)(kong)(kong)鋁(lv)單板(ban)的(de)孔(kong)(kong)(kong)徑、孔(kong)(kong)(kong)距大(da)小一致(zhi)(zhi)，不(bu)規則(ze)沖(chong)(chong)(chong)孔(kong)(kong)(kong)鋁(lv)單板(ban)（藝術沖(chong)(chong)(chong)孔(kong)(kong)(kong)鋁(lv)單板(ban)），其孔(kong)(kong)(kong)徑、孔(kong)(kong)(kong)距大(da)小不(bu)一致(zhi)(zhi)。

規則沖(chong)孔鋁(lv)單板(ban)(ban)的孔徑(jing)一(yi)般有(you)3mm、4mm、5mm、6mm等(deng)多種，理論上來說，沖(chong)孔鋁(lv)單板(ban)(ban)的孔徑(jing)也與其厚度(du)有(you)關(guan)，1.0毫(hao)米鋁(lv)板(ban)(ban)不能小于(yu)板(ban)(ban)的厚度(du)，1毫(hao)米鋁(lv)板(ban)(ban)要沖(chong)孔1.0毫(hao)米以(yi)上。

三、開孔鋁單板的沖孔率怎么算

開(kai)孔(kong)(kong)鋁(lv)(lv)單(dan)板(ban)的(de)沖(chong)(chong)孔(kong)(kong)率(lv)是(shi)(shi)指的(de)沖(chong)(chong)孔(kong)(kong)密度，一般(ban)通過公式可以計算出來(lai)，計算公式是(shi)(shi)：沖(chong)(chong)孔(kong)(kong)率(lv)=沖(chong)(chong)孔(kong)(kong)面積/整塊(kuai)沖(chong)(chong)孔(kong)(kong)鋁(lv)(lv)板(ban)面積，孔(kong)(kong)徑與孔(kong)(kong)距(ju)，共同(tong)決定了(le)沖(chong)(chong)孔(kong)(kong)鋁(lv)(lv)單(dan)板(ban)的(de)沖(chong)(chong)孔(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，還要考慮鋁(lv)板的(de)(de)強度和抗變形能力，尤其是應用于室外幕(mu)墻工程時。比如沖孔率大(da)于50%時，為了保證板面(mian)的(de)(de)平整度與效(xiao)果(guo)，不(bu)能用小(xiao)于3.0mm厚的(de)(de)鋁(lv)板。
