玻璃纖維針刺氈

玻璃纖維針刺氈是一種結(jié)構(gòu)合理、性能較好的過濾材料，以玻璃纖維為原料，用刺針對梳理后的短切玻纖氈進(jìn)行針刺，用機(jī)械方法使氈層玻纖之間、氈層玻纖與增強(qiáng)玻纖基布之間纖維相互纏結(jié)，纖網(wǎng)得以加固而制成的氈狀非織造布過濾材料。

它不僅具有玻纖織物耐高溫、耐腐蝕、尺寸穩(wěn)定、伸長收縮率極小、強(qiáng)度高的優(yōu)點，而且氈層纖維呈單纖維，三維微孔結(jié)構(gòu)，孔隙率高，對氣體過濾阻力小，是一種較高速、高效的高溫過濾材料。與其它的耐高溫化纖氈相比，其具有價格低、耐溫更高等特殊優(yōu)點，但其運行阻力高于一般化纖高溫濾材

1、斷熱性佳:根據(jù)物理原理，氣體的熱傳導(dǎo)率小、優(yōu)秀的斷熱材質(zhì)內(nèi)部均有很多空氣穴。而玻璃纖維針刺棉具有無數(shù)細(xì)小氣體，且纖維呈現(xiàn)不規(guī)則排列，為極佳隔熱材料，熱傳導(dǎo)系數(shù)0.2~0.040kcal/mhr。c之間;

2、不會燃燒:玻璃纖維的主要成分為硅化物(占50%以上)，具有不燃性、無變形、無脆化，耐高溫達(dá)700℃;

3、吸音率良:當(dāng)音波侵入玻璃纖維棉時，其能量會因與纖維及大小不同氣穴的摩擦，而被大量吸入。一般而言，吸音率皆高達(dá)90%以上，是防止雜音干擾的良才;

4、絕緣性高:玻璃纖維能耐高溫，機(jī)械性良好，且化學(xué)安定性高，是最佳的絕緣材料;

5、耐腐蝕性高:玻璃纖維不怕強(qiáng)酸、強(qiáng)堿，長時間不會減低其功能特性;

6、復(fù)原性好:玻璃纖維內(nèi)含無數(shù)固定氣穴，復(fù)原性極好。不怕任何沖擊震動，抗拉強(qiáng)度均1.0kg以上。

7、吸濕率低:吸濕率通常接近于零。

8、重量輕而軟:與其他隔熱材比較，玻璃纖維針刺氈的質(zhì)量最輕、最柔，若安裝在機(jī)械上，可減輕其重量與震動的負(fù)荷。

9、施工簡易:尺寸可依客戶來裁切。

玻璃纖維針刺氈可用于汽車工業(yè)中的隔音、吸音、減震、阻燃等，主要用于工業(yè)中的過濾領(lǐng)域;高溫?zé)煔膺^濾;玻璃纖維針刺氈廣泛應(yīng)用于炭黑、鋼鐵、有色金屬、化工、焚燒等行業(yè)的煙氣凈化和粉塵回收各種袋式除塵器。

Glass fiber needled Mat

Glass fiber needled Mat is a kind of filter material with a reasonable structure and good performance. It is made of glass fiber as raw material. After carding, the short-cut glass fiber mat is needled with a needle. By mechanical means, the fibers between the glass fibers in the mat layer and between the glass fibers in the mat layer and the reinforcing glass fiber base fabric are entangled with each other, and the fiber web is reinforced to form a felt-like nonwoven fabric filter material.

It not only possesses the advantages of glass fiber fabrics such as high-temperature resistance, corrosion resistance, dimensional stability, extremely small elongation and shrinkage rate, and high strength, but also the felt layer fibers are single-fiber, with a three-dimensional micro-porous structure, high porosity, and low resistance to gas filtration. It is a relatively high-speed and efficient high-temperature filtration material. Compared with other high-temperature resistant chemical fiber felts, it has special advantages such as lower price and higher temperature resistance, but its operating resistance is higher than that of general chemical fiber high-temperature filter materials.
