style="text-indent:25px">雞蛋棉原理:影響吸音棉吸聲效果的主要因素是產(chǎn)品的厚度，密度，和里外空流阻等。空氣流阻是單位厚度時(shí)材料兩側(cè)空氣氣壓和空氣流速之比?？諝?流阻是影響海棉吸聲隔音性能很重要的因素。流陽(yáng)太小說(shuō)明材料稀疏，空氣振動(dòng)容光煥發(fā)易穿過(guò)，吸聲性能下降。流陽(yáng)太大說(shuō)明材料密實(shí)，空氣振動(dòng)難以傳入，吸聲性能亦下降。所以在選擇吸音棉雕音棉時(shí)應(yīng)有相當(dāng)?shù)牧私饣蜃稍儗I(yè)人士。海棉具有很多內(nèi)外聯(lián)通的孔腺和氣泡，當(dāng)聲波射入到波浪其中時(shí)，可引起空隙中空氣振動(dòng)由于空氣的粘滯阻力，空氣與孔壁的摩擦使很大一-部分聲能轉(zhuǎn)達(dá)化成熱能，從而被子消耗達(dá)到吸音和隔音的效果。加上海棉的凹凸波浪形狀讓利余的聲波在凹凸反復(fù)的折射中漸漸減少。此外當(dāng)空(絕熱壓縮時(shí)空氣與孔壁之間不斷發(fā)生熱交換，由于執(zhí)導(dǎo)作用也會(huì)使一部分聲能轉(zhuǎn)化成熱能，從而達(dá)到吸音的效果。吸音的效果跟開孔的大小還有整張棉的厚度有著重要的關(guān)系，太薄的話即使能使吸音也只能吸- -小部份的。</p><p style="text-indent:25px">雞蛋棉用于隔音，其實(shí)也是有一定效果的，但綜合來(lái)講它的劣勢(shì)太多，當(dāng)然主要還是看你的用途了。好的隔音棉它首先是健康的材料，比如聚酯纖維。好的隔音棉它的性能很重要，否則不能保證效能，用了沒(méi)有多少效果而且有毒的隔音棉，那么作用其實(shí)是負(fù)的。好的吸音隔音材料，你參考一下梯度吸音棉就知道了。它由兩種不同熔點(diǎn)的聚酯纖維組成。生產(chǎn)過(guò)程中，當(dāng)烘箱加熱到低熔點(diǎn)纖維的熔點(diǎn)時(shí)，低熔點(diǎn)纖維就熔化成了一種膠粘劑，通過(guò)熱壓后成型。其環(huán)保性能是其較大的優(yōu)勢(shì)，檢測(cè)數(shù)據(jù)達(dá)到國(guó)家E1級(jí)，評(píng)價(jià)是能直接和人體接觸，是較接近自然而且對(duì)人體無(wú)害對(duì)環(huán)境無(wú)污染的高效吸音隔音材料。其防火性能是B1級(jí)，屬難燃產(chǎn)品。它的梯狀密度結(jié)構(gòu)決定了它的高效能吸音，是全頻吸音（而等密度的隔音材料，它是單頻吸音，只能吸收固定頻率的噪音，效果就要差得多）。吸音棉有的種類不止一種，看你是用在哪里了。</p><div

style="text-indent:25px">吸音棉有的種類不止一種，看你是用在哪里了。吸音棉種類：金字塔吸音棉、雞蛋棉、蘑菇棉、超密胺泡棉還有聚酯纖維吸音棉、巖棉、玻璃棉。如果你用在表面吸音，建議用金字塔吸音棉、雞蛋棉、蘑菇棉、超密胺泡棉。因?yàn)樗鼈儾粌H顏色豐富，而且表面也不做其他的裝飾。裝飾效果好，而且吸收噪音的功能也很好。如果你是做的隔音的基層。要往里面填充吸音棉，建議用聚酯纖維吸音棉、巖棉、玻璃棉。因?yàn)檫@幾種不適合用在表面，它們有的柔軟性好，有的隔音吸音效果，阻止聲音從外界傳人，阻止聲音從室內(nèi)傳到室外。雞蛋棉是經(jīng)過(guò)設(shè)備特殊處理形成一面凹凸波浪形狀的。無(wú)錫吸音雞蛋棉</p><p

style="text-indent:25px">吸音棉（雞蛋棉）填充量通常是封閉音箱多點(diǎn)，倒相音箱少一點(diǎn)，嚴(yán)格上是需要通過(guò)科學(xué)計(jì)算然后通過(guò)實(shí)驗(yàn)決定的。另外一個(gè)影響因素是，如果箱體理論上非常堅(jiān)固，自身可以克服與低音喇叭共振的話，吸音棉可以使用很少或不使用。吸音棉一般可以選擇在音箱內(nèi)部均勻貼上一層3公分厚度，可以5個(gè)面都貼，用乳白膠粘上。發(fā)燒友搞DIY音箱時(shí)，吸音棉填充的量，主要是看音箱整體出來(lái)的聲音做增減，如果箱體的共鳴聲太大，可以加上適量減小共震。多加了也不好，會(huì)導(dǎo)至箱體聲音出來(lái)發(fā)悶。無(wú)錫吸音雞蛋棉</p></p><br
