  環保吸音板在基材(cai)(cai)安裝上(shang),根據基材(cai)(cai)的(de)材(cai)(cai)質所散發含甲醛(quan)的(de)釋放量(liang)來區(qu)分(fen)等級(ji),一共(gong)有(you)分(fen)有(you)E0,E1,E2級(ji),其中E0級(ji)為環保最(zui)高,E1其次,E2甲醛(quan)釋放量(liang)相(xiang)對來說最(zui)高。直接(jie)用(yong)于(yu)室(shi)內安裝的(de)話,E1級(ji)就屬于(yu)合格(ge)了。

  按結構分類(lei):

  ① 吸(xi)音尖劈(pi)。

  吸音尖(jian)劈(pi)是一(yi)種(zhong)用(yong)(yong)(yong)于強吸聲(sheng)場的(de)(de)特(te)殊吸聲(sheng)結(jie)構(gou)材(cai)料,采用(yong)(yong)(yong)多孔(kong)性(xing)(xing)(或(huo)纖維性(xing)(xing))材(cai)料成(cheng)型切(qie)割,制作成(cheng)錐形或(huo)尖(jian)劈(pi)狀吸聲(sheng)體,堅挺(ting)不變形。吸音尖(jian)劈(pi)適用(yong)(yong)(yong)于強氣流環境,主要對象(xiang)是高(gao)質量消聲(sheng)室,對低(di)頻的(de)(de)吸收更(geng)(geng)為(wei)有效,能消除駐波,達到杜絕回聲(sheng)的(de)(de)要求,低(di)截止頻率吸聲(sheng)系數大于0.99.用(yong)(yong)(yong)聚(ju)酯制成(cheng)的(de)(de)V型、W型吸音尖(jian)劈(pi)與(yu)普通吸聲(sheng)尖(jian)劈(pi)相比具有占用(yong)(yong)(yong)體積小價格更(geng)(geng)合(he)理(li)等特(te)點。

  ② 擴散體。

  擴(kuo)散(san)(san)體吸音(yin)(yin)板(ban)(ban)除(chu)了具有平面吸音(yin)(yin)板(ban)(ban)的所(suo)有功能(neng)(neng)以外,還能(neng)(neng)通過它(ta)的立體表(biao)面對音(yin)(yin)波(bo)進(jin)行(xing)不同角度(du)的傳導,消除(chu)音(yin)(yin)波(bo)在擴(kuo)散(san)(san)過程(cheng)中的盲區,改善(shan)音(yin)(yin)質,平衡音(yin)(yin)響,削薄重音(yin)(yin),削弱高(gao)音(yin)(yin),對低音(yin)(yin)進(jin)行(xing)補償。

  產品結構(gou):

  在(zai)中密度纖(xian)維板(ban)正面(mian)(mian)開形(xing)式(shi)立體三角或圓柱(zhu)形(xing)的槽,背面(mian)(mian)開圓孔的結構吸(xi)聲材料,飾面(mian)(mian)噴漆(可按客戶要求選擇顏色(se)),背貼(tie)防火吸(xi)音布。

  應用(yong)范圍:

  電視(shi)臺、電影院(yuan)、歌劇院(yuan)、音(yin)樂廳、會(hui)議中(zhong)心、體育館、音(yin)響室、家居、商(shang)場、酒店、卡(ka)拉OK、酒廊、餐廳等。

  ③鋁蜂(feng)窩穿孔。

  鋁蜂(feng)(feng)(feng)窩(wo)穿(chuan)(chuan)孔(kong)(kong)吸(xi)音板(ban)(ban)(ban)(ban)的構造結(jie)構為(wei)穿(chuan)(chuan)孔(kong)(kong)面板(ban)(ban)(ban)(ban)與(yu)(yu)穿(chuan)(chuan)孔(kong)(kong)背板(ban)(ban)(ban)(ban),依靠優(you)質膠(jiao)粘劑與(yu)(yu)鋁蜂(feng)(feng)(feng)窩(wo)芯直接粘接成鋁蜂(feng)(feng)(feng)窩(wo)夾層結(jie)構,蜂(feng)(feng)(feng)窩(wo)芯與(yu)(yu)面板(ban)(ban)(ban)(ban)及背板(ban)(ban)(ban)(ban)間貼上一層吸(xi)音布。由(you)于蜂(feng)(feng)(feng)窩(wo)鋁板(ban)(ban)(ban)(ban)內的蜂(feng)(feng)(feng)窩(wo)芯分隔成眾多的封閉小(xiao)室(shi),阻(zu)止了(le)空(kong)氣流(liu)動(dong),使聲波受到阻(zu)礙,提(ti)高了(le)吸(xi)聲系數(可達到0.9以上),同時提(ti)高了(le)板(ban)(ban)(ban)(ban)材自(zi)(zi)身(shen)強度,使單(dan)塊(kuai)板(ban)(ban)(ban)(ban)材的尺寸可以做到更大(da),進(jin)一步加大(da)了(le)設(she)(she)(she)計(ji)(ji)自(zi)(zi)由(you)度。可以根(gen)據室(shi)內聲學設(she)(she)(she)計(ji)(ji),進(jin)行不同的穿(chuan)(chuan)孔(kong)(kong)率設(she)(she)(she)計(ji)(ji),在一定的范圍內控制(zhi)組合結(jie)構的吸(xi)音系數,既(ji)達到設(she)(she)(she)計(ji)(ji)效果,又能夠合理控制(zhi)造價。通(tong)過(guo)控制(zhi)穿(chuan)(chuan)孔(kong)(kong)孔(kong)(kong)徑、孔(kong)(kong)距,并可根(gen)據客戶使用(yong)要求(qiu)改(gai)變穿(chuan)(chuan)孔(kong)(kong)率,最大(da)穿(chuan)(chuan)孔(kong)(kong)率<30%,孔(kong)(kong)徑一般選(xuan)用(yong)∮2.0、∮2.5、∮3.0等(deng)規格,背板(ban)(ban)(ban)(ban)穿(chuan)(chuan)孔(kong)(kong)要求(qiu)與(yu)(yu)面板(ban)(ban)(ban)(ban)相同,吸(xi)音布采(cai)用(yong)優(you)質的無(wu)紡布等(deng)吸(xi)聲材料。

  ④木質穿孔。

  孔石膏(gao)板(ban)有(you)(you)貫通于石膏(gao)板(ban)正(zheng)面(mian)和背面(mian)的圓(yuan)柱形(xing)孔眼, 在石膏(gao)板(ban)背面(mian)粘(zhan)貼(tie)具有(you)(you)透氣(qi)性的背覆材(cai)料(liao)(liao)和能吸(xi)(xi)(xi)收(shou)(shou)入射聲(sheng)(sheng)能的吸(xi)(xi)(xi)聲(sheng)(sheng)材(cai)料(liao)(liao)等組(zu)臺而成(cheng)。吸(xi)(xi)(xi)聲(sheng)(sheng)機理是(shi)(shi)材(cai)料(liao)(liao)內部有(you)(you)大量微小的連(lian)通的孔隙, 聲(sheng)(sheng)波沿(yan)著(zhu)這(zhe)些(xie)孔隙可以深入材(cai)料(liao)(liao)內部,與材(cai)料(liao)(liao)發(fa)生摩擦(ca)作用將聲(sheng)(sheng)能轉化(hua)為(wei)熱(re)能。多(duo)孔吸(xi)(xi)(xi)聲(sheng)(sheng)材(cai)料(liao)(liao)的吸(xi)(xi)(xi)聲(sheng)(sheng)特性是(shi)(shi)隨著(zhu)頻(pin)率的增高吸(xi)(xi)(xi)聲(sheng)(sheng)系(xi)數逐漸(jian)增大, 這(zhe)意味(wei)著(zhu)低(di)頻(pin)吸(xi)(xi)(xi)收(shou)(shou)沒有(you)(you)高頻(pin)吸(xi)(xi)(xi)收(shou)(shou)好。
