style="text-indent:25px">怎么消除噪音？雞蛋棉是個(gè)不錯(cuò)的選擇。人類一直在尋找降低噪音的辦法，特別是一些特殊的行業(yè)就需要噪音越小越好，通常降低噪音有三種辦法。一種方法是在發(fā)聲的源頭上控制噪音，也就是說讓發(fā)聲體減小或者是停止振動(dòng)，這種辦法是從發(fā)聲源頭直接讓噪音消失，當(dāng)直接讓發(fā)聲源停止振動(dòng)后，就沒有辦法持續(xù)在空氣中產(chǎn)生振動(dòng)。第二種就是在人接收聲音的耳朵處將噪音阻隔在外，例如說帶上耳塞就能有效的降低噪音進(jìn)入人耳的音量，即便是不改變發(fā)聲源和傳播途徑，也能夠有效降低噪音。第三種就是讓聲音在傳播過程中通過阻擋，過濾以及吸收等方法，將噪音逐漸降低甚至讓其停止傳播。當(dāng)空氣絕熱壓時(shí),空氣與孔壁之間不斷發(fā)生熱交換也會(huì)使一部分聲能轉(zhuǎn)化成熱量。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="彩色雞蛋棉訂做,雞蛋棉" src="https://tyunfile.71360.com/UploadFile/Shwwjp/637357768614746094/8014917.png"></div><p 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。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。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。雞蛋棉由于熱傳導(dǎo)作用，也會(huì)使一部分聲能轉(zhuǎn)化成熱能。彩色雞蛋棉訂做</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)。彩色雞蛋棉訂做</p><p style="text-indent:25px">雞蛋棉：1、防火性、結(jié)構(gòu)抗震性：具有較高的防火等級(jí)A級(jí)，聲影美隔離棉由于纖維細(xì)而長，使得整體結(jié)構(gòu)強(qiáng)度高，抗拉、抗振性能優(yōu)越，無論安裝或長期使用都不易出現(xiàn)下垂、散落或坍塌的現(xiàn)象。完全符合國家的相關(guān)要求。 2、保溫性、環(huán)保性：隔離棉是以無色平板玻璃和石英砂為主要原材料制成的無機(jī)類保溫材料，具有優(yōu)越的保溫性，為綠色建材產(chǎn)品，建筑廢料可循環(huán)使用，完全符合環(huán)保要求。3、化學(xué)性、聲學(xué)性：隔離棉內(nèi)部多孔結(jié)構(gòu)，材料尺寸穩(wěn)定性好，使其具有優(yōu)越的吸聲能力，不易受高溫、雷電雨水、陽光、酸堿等自然和人為因素的破壞和侵蝕，有效提高室內(nèi)環(huán)境的舒適度。4、透氣性、憎水性：多孔開放結(jié)構(gòu)，比其他保溫材料具有更好的透氣性，有助于室內(nèi)和墻體的濕氣及時(shí)擴(kuò)散，減少霉菌生長可能性，有助于延長建筑物使用壽命，幕墻用憎水隔離棉屬于高憎水隔離棉產(chǎn)品，其憎水率高達(dá)99%，受潮后易自干，確保其長期有效的保溫性能，提高室內(nèi)環(huán)境的舒適度。5、自重性：隔離棉具有良好的保溫隔音性能，使得其低密度的產(chǎn)品就能滿足相應(yīng)規(guī)范的節(jié)能要求，隔離棉是A級(jí)防火保溫材料當(dāng)中較輕質(zhì)的材料，既可減輕建筑物自身承重還能方便施工，提高施工效率。彩色雞蛋棉訂做</p></p><br
