style="text-indent:25px">雞蛋棉又名波浪棉、波峰棉。是吸音棉中的一種。雞蛋棉是經(jīng)過設(shè)備特殊處理形成一面凸凹波浪形的一種海棉，其內(nèi)部充滿細(xì)小空隙及半開孔結(jié)構(gòu)能大量吸收射入的聲波能量對(duì)聲波起到衰減作用，降低室內(nèi)反射聲的干擾和回響，提高聲音的純度，是吸音降噪材料的高性能產(chǎn)品，西安蜂窩型吸音棉銷售，西安蜂窩型吸音棉銷售。雞蛋棉分類：（1）防火于不防火：雞蛋棉又分為防火雞蛋棉和不防火雞蛋棉，西安蜂窩型吸音棉銷售。防火雞蛋棉是添加了阻燃劑，阻燃的標(biāo)準(zhǔn)是離火即息的效果。（2）顏色分類:防火雞蛋棉一般會(huì)有黑色和白色，不防火的雞蛋棉可做成多種顏色，例如紅色、黃色、藍(lán)色、黑色等顏色。（3）厚度和密度：雞蛋棉的厚度常規(guī)說法是兩張波峰重合后的厚度，單張的厚度一般會(huì)是商家所說的雙張厚度的3/4厚度。隨著雞蛋棉的吸音厚度和密度的變化，雞蛋棉的吸音效果與雞蛋棉的厚度和密度成正比。選擇密度的時(shí)候可根據(jù)實(shí)際用途選擇厚度。雞蛋棉由哪些材料組成？西安蜂窩型吸音棉銷售</p><div

style="text-indent:25px">使用雞蛋棉降低和有效緩解底盤的金屬疲勞，延長(zhǎng)車體使用壽命。產(chǎn)生金屬疲勞的原因是因?yàn)榻饘賰?nèi)部并不均勻的結(jié)構(gòu)，造成應(yīng)力傳遞的不平衡，有的地方會(huì)成為應(yīng)力集中區(qū)。與此同時(shí)，金屬內(nèi)部的缺陷處還存在許多微小的裂紋。在力的持續(xù)作用下，裂紋會(huì)越來越大，材料中能夠傳遞應(yīng)力部分越來越少，直至剩余部分不能繼續(xù)傳遞負(fù)載時(shí)，金屬構(gòu)件就會(huì)全部毀壞。據(jù)**認(rèn)證，任何一種金屬在各種外力的反復(fù)長(zhǎng)時(shí)間作用下，都會(huì)產(chǎn)生疲勞狀態(tài)，而且，一旦產(chǎn)生疲勞就會(huì)因不能得到恢復(fù)而造成十分嚴(yán)重的后果。據(jù)150多年來的統(tǒng)計(jì)，金屬部件中有80%以上的損壞是由于疲勞而引起的。在我們的日常生活中，也同樣會(huì)發(fā)生金屬疲勞帶來危害的現(xiàn)象。如馬路上行走的自行車突然前叉折斷，刨地時(shí)鐵鎬從中一分為二等，打個(gè)簡(jiǎn)單的比方，一段細(xì)鐵絲反復(fù)折彎十幾次就會(huì)在折彎處產(chǎn)生斷裂也就是這個(gè)道理。西安蜂窩型吸音棉銷售雞蛋棉無味、環(huán)保衛(wèi)生，是理想的室內(nèi)隔音/吸音、音頻反射材料。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="西安蜂窩型吸音棉銷售,雞蛋棉" src="https://tyunfile.71360.com/UploadFile/Shwwjp/637357768784140625/8872586.png"></div><p style="text-indent:25px">吸音材料：吸聲材料大多為疏松多孔的材料，如礦渣棉、毯子等，其吸聲機(jī)理是聲波深入材料的孔隙，且孔隙多為內(nèi)部互相貫通的開口孔，受到空氣分子摩擦和粘滯阻力，以及使細(xì)小纖維作機(jī)械振動(dòng)，從而使聲能轉(zhuǎn)變?yōu)闊崮?。這類多孔性吸聲材料的吸聲系數(shù)，一般從低頻到高頻逐漸增大，故對(duì)高頻和中頻的聲音吸收效果較好. 吸聲降噪：在車間、廠房、大的開敞式空間（機(jī)場(chǎng)大廳、辦公室、展廳等），由于混響聲的原因，會(huì)使噪聲比之同樣聲源在室外高10-15dB。，通過在室內(nèi)布置吸聲材料，可以使混響聲被吸掉，降低室內(nèi)噪聲。吸聲降噪至多可以獲得10-15dB的降噪量。降噪量=10lg(A0/A1),未加入吸聲材料時(shí)室內(nèi)吸聲量越少，加入吸聲材料后室內(nèi)吸聲量越多，降噪效果越好。</p><p style="text-indent:25px">噪音是如何產(chǎn)生的：要想知道吸音棉是如何阻擋噪音的，首先就要了解噪音是如何產(chǎn)生的，其實(shí)，聲音的產(chǎn)生就是由物體振動(dòng)所產(chǎn)生的波，再通過固體，氣體或者液體這些介質(zhì)傳播后，被人的耳朵接收到的一種波動(dòng)現(xiàn)象。在生活中當(dāng)我們敲門，說話或者發(fā)出**聲時(shí)，它們的振動(dòng)就會(huì)在空氣中引起空氣分子按照一定節(jié)奏振動(dòng)，讓周圍的空氣產(chǎn)生波動(dòng)變化，形成向外擴(kuò)散的波，這就是聲波的產(chǎn)生過程。這種聲波會(huì)一直向外延續(xù)，直到振動(dòng)逐漸減弱并消失為止，這就好像將一塊石頭扔進(jìn)水中一樣，中間的波浪較清楚，越往外圈波浪越大但會(huì)越模糊，直到后來波浪會(huì)完全消失掉。雞蛋棉內(nèi)部充滿細(xì)小空隙及半開孔結(jié)構(gòu),能大量吸收射入的聲波能量對(duì)聲波起到衰減作用。</p><div

style="text-indent:25px">音箱內(nèi)部加入吸音棉（雞蛋棉）的作用主要是調(diào)節(jié)Q值，填充的吸音棉能吸收喇叭反向的聲波，防止聲波反射與折射，擾亂正常的聲波。厚實(shí)的吸音棉是用膠水貼在音箱內(nèi)部的箱體壁上，厚實(shí)材質(zhì)一般使用玻璃棉、礦棉等；柔軟的吸音棉則可以直接塞在音箱里面，柔軟材質(zhì)一般使用棉花、聚酯吸音棉等。封閉式音箱由于不需要導(dǎo)向孔傳出揚(yáng)聲器背面的聲波，所以箱體內(nèi)需要安裝多一點(diǎn)吸音棉以達(dá)到盡可能多地消除箱體震動(dòng)，從而獲得較佳低音表現(xiàn)。倒相式音箱可以不加或稍加吸音材料，因?yàn)榈瓜嗍揭粝鋬?nèi)部的聲能可以通過倒相孔釋放出來。雞蛋棉安裝也可以直接用釘子釘在墻上（注意釘子頭部大小）。西安蜂窩型吸音棉銷售</p><p
