style="text-indent:25px">多空材料的空氣體積與材料的總體積之間的比例就是孔隙率，通常用百分比進(jìn)行表示。通常情況下，多孔吸聲材料的孔隙率在７０％左右，有些高達(dá)９０％左右。多空材料的孔隙比較好要細(xì)小且均勻分布，增加材料內(nèi)的筋絡(luò)面積，促進(jìn)噪音的吸收。材料厚度的影響：同一種多孔吸音材料的厚度一定，在低頻范圍內(nèi)吸聲系數(shù)相對較低，而隨著頻率的增加吸聲系數(shù)快速增加，達(dá)到高頻范圍時，吸聲系數(shù)的變化不明顯。但材料的厚度繼續(xù)增加，高頻吸收噪音效果增加不明顯，而厚度增加對低頻吸聲系數(shù)有較大的影響。通過實(shí)驗(yàn)表明，同一類多孔材料，在堆密度相同時，厚度和頻率的乘積對吸聲系數(shù)有著決定性的作用。當(dāng)材料的厚度為之前的兩倍時，頻譜曲線向低頻方向移動一個倍的頻帶。河南茂源玻璃棉卷氈信賴推薦</p><div

style="text-indent:25px">吸音棉是多孔吸聲材料，當(dāng)聲波在空氣中引起振動時，吸音棉透氣性的物理參數(shù)會使微量的空氣從多孔材料的孔隙中通過，此時材料的兩面的靜壓差和氣流線速度之間的比就是材料的流阻。吸引材料的內(nèi)部微孔數(shù)量、大小以及互相連通的程度等因素都會影響流阻的大小，流阻的大小對材料吸音作用有著重要的影響。一定厚度的多空材料應(yīng)該對應(yīng)一個合理的流阻數(shù)值，過高或過低都會影響材料的吸音性能。因此，要對材料的流阻進(jìn)行調(diào)整，將流阻值控制在科學(xué)的范圍內(nèi)，發(fā)揮出其比較大的作用。</p><p style="text-indent:25px">荊州開發(fā)區(qū)茂源保溫材料廠和大家一起來認(rèn)識下常見的吸聲材料有哪些。一般來說材料吸聲主要通過兩個方面實(shí)現(xiàn)：一是靠材料本身的吸聲特性，如玻璃棉、巖棉等纖維或多孔材料。簡單原理就是當(dāng)聲波入射到材料表面順著微孔穿入到內(nèi)部，由于反射摩擦以及空氣黏滯阻力，使一部分聲能損耗轉(zhuǎn)變?yōu)闊崮埽硗鈿怏w壓縮放熱、膨脹吸熱，進(jìn)行熱交換也能使聲能被吸收。另一方面是靠吸聲結(jié)構(gòu)，其材料本身不具備吸聲特性，但經(jīng)過打孔、開縫等加工和表面處理制成某種結(jié)構(gòu)而產(chǎn)生吸聲效果，主要有薄膜、薄板，以及空腔、穿孔板等共振吸聲結(jié)構(gòu)等。原理是共振結(jié)構(gòu)在聲波激發(fā)下振動，振動結(jié)構(gòu)由于本身的內(nèi)摩擦和與空氣間的摩擦把部分振動能量轉(zhuǎn)換為熱能而消耗掉，實(shí)現(xiàn)吸聲效果。</p><div

style="text-indent:25px">多孔材料背后空氣層的影響：多孔材料的背后空氣層的厚薄程度，對其吸聲功能有著重要的影響。當(dāng)多孔材料與剛性壁有一定的空間時，材料的背面會出現(xiàn)一定的空腔，增加了材料的有效厚度，對其低頻噪音吸收功能有著一定的影響。當(dāng)多孔材料的厚度與堆密度一定時，背后空氣層變化的影響較大，當(dāng)空氣層厚度為１／４波長的奇數(shù)倍時，吸聲系數(shù)達(dá)到比較大值。外部使用條件變化的影晌：首先，溫度的影響和變化，會使聲速和波長變化，也會因?yàn)榭諝忏@滯性導(dǎo)致流阻的變化，影響材料的吸聲功能。通常，溫度升高，高頻吸聲頻率的曲線移向高頻；其次，濕度的影響，多孔材料吸收水分，導(dǎo)致材料的本質(zhì)發(fā)生變化，材料的孔隙率下降，吸聲性能受到影響。河南茂源玻璃棉卷氈推薦</p><p
