style="text-indent:25px">蜂窩棉使用效果測(cè)評(píng): 要你的棉堵水，就可以放這種棉，提升過水性。從結(jié)構(gòu)上來，兩層網(wǎng)夾著一層帶孔的棉。實(shí)際的過水點(diǎn)就是中層棉的孔上。這有點(diǎn)像干濕分離的雨淋孔?；旧?9%的水都是經(jīng)過這些孔，而上下兩層網(wǎng)也只是起到類似絲襪的隔離效果。單從過濾棉的角度去看它，它是一張類似套了兩層絲襪的棉，以至于后續(xù)的產(chǎn)品當(dāng)中，出現(xiàn)了蜂窩袋。按照30ml飼料一天一喂的頻率，使用沉淀過濾時(shí)，可以保持有1個(gè)月不堵，沒積水，1個(gè)半月后積水了，堵了之后，把所有棉都清洗干凈，然后不用沉淀過濾再測(cè)試一次，三天就積水，一周就堵了，關(guān)鍵一點(diǎn)，蜂窩棉的堵，你看著去很干凈或者說看不出哪里堵，但作用時(shí)，的確就會(huì)堵，而堵的原因就在于上下兩層網(wǎng)。就像絲襪過濾，新的絲襪是過水的，隨著時(shí)間使用，無論你怎么洗，都沒有新的絲襪那么好過水。雞蛋棉是一種不錯(cuò)的隔音材料。福州橡膠隔音棉</p><p

style="text-indent:25px">說雞蛋棉是一種很好的隔音材料。隔音棉:隔音棉有良好的隔熱效果，在汽車引擎蓋內(nèi)粘貼后，可有效避免發(fā)動(dòng)機(jī)的高溫直接傳至引擎蓋，以此保護(hù)引擎蓋表面車漆，同時(shí)避免雨天時(shí)引擎蓋霧氣騰騰視線影響。隔音棉另一個(gè)作用就是隔熱，就它可以減少發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)傳到引擎蓋表面的熱量，安裝有引擎蓋隔音棉的車輛雨天時(shí)基本不會(huì)產(chǎn)生白霧。陰雨天和冬天，由于外部氣溫與發(fā)動(dòng)機(jī)溫差較大，再加上雨水等對(duì)引擎蓋的沖刷等共同作用，會(huì)加速漆面的氧化。隔熱棉可以在一定程度上保護(hù)引擎蓋的漆面。物體震動(dòng)產(chǎn)生聲音→聲波在空氣中傳遞→棉具有多纖維結(jié)構(gòu)→聲波通過棉時(shí)經(jīng)過無數(shù)纖維的反射、相互疊加、碰撞，聲波能量轉(zhuǎn)化為熱能→聲波強(qiáng)度減弱→聲音消失。廣州阻燃蜂窩棉廠商</p><p
