巖棉板廠家為您介紹巖棉板的各種性能

　　巖(yan)棉板(ban)廣泛應用(yong)于船舶、冶金(jin)、電(dian)力、建(jian)筑等行業(ye)。該材料施工安(an)裝(zhuang)方便(bian)，節能效果顯著，性(xing)價(jia)比高。巖(yan)棉板(ban)可應用(yong)于工業(ye)、建(jian)筑、船舶和(he)農(nong)業(ye)。然(ran)而，許多人對巖(yan)棉板(ban)的特點(dian)了(le)解(jie)不夠全面。讓我們來看看：

　　1.保溫性能

　　目(mu)前(qian)，在家庭建筑保溫領域，人們對(dui)巖(yan)棉(mian)板(ban)(ban)的(de)(de)(de)應用有一(yi)個普(pu)遍的(de)(de)(de)誤解：人們認為(wei)巖(yan)棉(mian)板(ban)(ban)的(de)(de)(de)機(ji)(ji)械強度與(yu)密度是(shi)分不開的(de)(de)(de)，這兩個指標是(shi)一(yi)種成比例的(de)(de)(de)關系，即為(wei)了提高機(ji)(ji)械強度，必(bi)須(xu)提高巖(yan)棉(mian)的(de)(de)(de)密度。這樣會(hui)提高巖(yan)棉(mian)板(ban)(ban)的(de)(de)(de)導(dao)熱(re)率，從而削弱巖(yan)棉(mian)板(ban)(ban)的(de)(de)(de)隔(ge)熱(re)性(xing)能，給員工的(de)(de)(de)施(shi)工帶來(lai)不必(bi)要的(de)(de)(de)麻煩。正(zheng)確的(de)(de)(de)方法是(shi)在不犧(xi)牲巖(yan)棉(mian)板(ban)(ban)機(ji)(ji)械強度的(de)(de)(de)情況下(xia)，在生(sheng)產過程(cheng)中保持巖(yan)棉(mian)板(ban)(ban)的(de)(de)(de)平均密度，盡產品的(de)(de)(de)導(dao)熱(re)系數。事實(shi)上，巖(yan)棉(mian)板(ban)(ban)的(de)(de)(de)導(dao)熱(re)性(xing)變化與(yu)纖維的(de)(de)(de)直徑和(he)方向以及(ji)巖(yan)棉(mian)板(ban)(ban)的(de)(de)(de)密度有關。總之，導(dao)熱(re)率越低，保溫效果越好。

　　2.機械強度高，負荷低

　　定向巖(yan)棉(mian)板采(cai)用非常合理的(de)巖(yan)棉(mian)纖(xian)維布局，確保巖(yan)棉(mian)板的(de)上密(mi)度(du)(du)(du)遠大(da)于下(xia)密(mi)度(du)(du)(du)。目的(de)是提(ti)高定向巖(yan)棉(mian)板的(de)表面強度(du)(du)(du)。該方法(fa)生產(chan)的(de)巖(yan)棉(mian)板不僅能承受(shou)長期均(jun)勻載荷(he)(he)，還能將點(dian)載荷(he)(he)轉化為均(jun)勻載荷(he)(he)，從而提(ti)高整(zheng)個建(jian)筑(zhu)中(zhong)巖(yan)棉(mian)板的(de)抗壓(ya)強度(du)(du)(du)。

　　與(yu)普通巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)板(ban)(ban)相比(bi)，定(ding)向巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)板(ban)(ban)內側具有(you)一定(ding)的(de)柔軟(ruan)度(du)(du)。因(yin)此(ci)，施工(gong)(gong)過程中(zhong)更容易緊密粘附(fu)在(zai)基材上，避免循環空氣層(ceng)造(zao)成的(de)熱損(sun)失，降低施工(gong)(gong)難度(du)(du)，提(ti)高保溫效果。定(ding)向巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)板(ban)(ban)的(de)機(ji)械(xie)強度(du)(du)也(ye)與(yu)巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)纖(xian)(xian)維本身的(de)性(xing)能(neng)密切相關(guan)。從(cong)巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)纖(xian)(xian)維的(de)化(hua)(hua)學成分(fen)來看，酸性(xing)氧(yang)化(hua)(hua)物(wu)有(you)利(li)于提(ti)高巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)板(ban)(ban)的(de)彈(dan)性(xing)。堿性(xing)氧(yang)化(hua)(hua)物(wu)雖然能(neng)降低熔融溫度(du)(du)和粘度(du)(du)，但(dan)不利(li)于長巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)纖(xian)(xian)維的(de)生產，在(zai)高濕度(du)(du)環境下性(xing)能(neng)不穩定(ding)。因(yin)此(ci)，定(ding)向巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)板(ban)(ban)中(zhong)堿性(xing)氧(yang)化(hua)(hua)物(wu)含量較(jiao)低。纖(xian)(xian)維紗線(xian)在(zai)巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)生產過程中(zhong)打褶(zhe)，使纖(xian)(xian)維與(yu)水平(ping)方(fang)向交錯成一定(ding)角度(du)(du)。目(mu)的(de)是將(jiang)巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)纖(xian)(xian)維結構從(cong)水平(ping)纖(xian)(xian)維結構轉變為(wei)垂直纖(xian)(xian)維結構，從(cong)而提(ti)高巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)板(ban)(ban)的(de)綜合機(ji)械(xie)強度(du)(du)。此(ci)外，由于巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)纖(xian)(xian)維中(zhong)堿性(xing)氧(yang)化(hua)(hua)物(wu)的(de)含量相對較(jiao)低，定(ding)向巖(yan)(yan)(yan)(yan)棉(mian)(mian)(mian)(mian)板(ban)(ban)也(ye)具有(you)較(jiao)好的(de)耐老化(hua)(hua)性(xing)和厭水性(xing)。

　　3.防水性能

　　提高定(ding)向巖(yan)棉板的(de)(de)防(fang)水(shui)(shui)性能(neng)主要(yao)有兩(liang)種方法：1。通過自身(shen)的(de)(de)纖(xian)維(wei)布置結構。2.添加適量的(de)(de)防(fang)水(shui)(shui)劑。良好的(de)(de)防(fang)水(shui)(shui)劑可(ke)用于巖(yan)棉纖(xian)維(wei)的(de)(de)表面處理，防(fang)水(shui)(shui)劑牢固附著在每個巖(yan)棉纖(xian)維(wei)的(de)(de)表面，形成穩定(ding)耐(nai)用的(de)(de)網(wang)絡結構。在防(fang)水(shui)(shui)劑的(de)(de)作(zuo)用下(xia)，水(shui)(shui)滴不能(neng)進(jin)入巖(yan)棉纖(xian)維(wei)，因此提高了巖(yan)棉板的(de)(de)防(fang)水(shui)(shui)性能(neng)。
