手工巖棉板的老化期有多長？手工巖棉板這個理論(lun)認(ren)為巖(yan)棉(mian)(mian)(mian)纖(xian)維(wei)是(shi)一種無(wu)機纖(xian)維(wei)，不會(hui)(hui)老(lao)化(hua)(hua)。在實際的(de)(de)巖(yan)棉(mian)(mian)(mian)產品(pin)中，除了(le)巖(yan)棉(mian)(mian)(mian)之外，還(huan)添加了(le)一定量的(de)(de)酚(fen)醛(quan)樹(shu)(shu)脂(zhi)和防(fang)(fang)水劑。這類有(you)機物在使用(yong)中會(hui)(hui)出(chu)現不同程度的(de)(de)老(lao)化(hua)(hua)，導致巖(yan)棉(mian)(mian)(mian)產品(pin)使用(yong)功(gong)能的(de)(de)喪(sang)失——老(lao)化(hua)(hua)。棉(mian)(mian)(mian)制品(pin)疏水劑的(de)(de)老(lao)化(hua)(hua)是(shi)由(you)于(yu)疏水膜被破(po)壞，降低了(le)其疏水率。酚(fen)醛(quan)樹(shu)(shu)脂(zhi)的(de)(de)老(lao)化(hua)(hua)現象是(shi)粉化(hua)(hua)，會(hui)(hui)明顯降低產品(pin)的(de)(de)強度。然(ran)而(er)，目前沒有(you)公認(ren)的(de)(de)不同酚(fen)醛(quan)樹(shu)(shu)脂(zhi)和防(fang)(fang)水劑配方的(de)(de)老(lao)化(hua)(hua)時間。

手(shou)工(gong)(gong)巖(yan)(yan)棉(mian)(mian)(mian)板(ban)(ban)(ban)產(chan)(chan)品為(wei)什么要(yao)防潮(chao)？手(shou)工(gong)(gong)巖(yan)(yan)棉(mian)(mian)(mian)板(ban)(ban)(ban)是一種高(gao)吸(xi)水(shui)性的(de)(de)無(wu)機(ji)纖維(wei)棉(mian)(mian)(mian)。手(shou)工(gong)(gong)巖(yan)(yan)棉(mian)(mian)(mian)板(ban)(ban)(ban)被(bei)水(shui)浸泡(pao)后，導熱系數大(da)大(da)增加(jia)，機(ji)械(xie)強度明顯下降(jiang)，尺寸明顯變化，保(bao)溫(wen)功能(neng)(neng)完全喪失(shi)，失(shi)去使用功能(neng)(neng)。因此，手(shou)工(gong)(gong)巖(yan)(yan)棉(mian)(mian)(mian)板(ban)(ban)(ban)產(chan)(chan)品必須采取防潮(chao)措(cuo)施，以(yi)具(ju)有良好(hao)的(de)(de)保(bao)溫(wen)性能(neng)(neng)、機(ji)械(xie)強度和(he)較小的(de)(de)尺寸變化率(lv)。一般(ban)來說，為(wei)了提高(gao)手(shou)工(gong)(gong)巖(yan)(yan)棉(mian)(mian)(mian)板(ban)(ban)(ban)的(de)(de)防潮(chao)性能(neng)(neng)，在巖(yan)(yan)棉(mian)(mian)(mian)纖維(wei)中添加(jia)防水(shui)劑，使手(shou)工(gong)(gong)巖(yan)(yan)棉(mian)(mian)(mian)板(ban)(ban)(ban)的(de)(de)加(jia)濕(shi)率(lv)達到98%以(yi)上(shang)，質量吸(xi)濕(shi)率(lv)小于5-10%。

隔熱技術應用于建筑物以保(bao)護結構墻。在(zai)眾多保(bao)溫材(cai)料市場中，手(shou)工巖(yan)(yan)棉板(ban)脫(tuo)穎而出。如今，保(bao)溫節能的趨(qu)勢不可逆轉(zhuan)選擇保(bao)溫材(cai)料要考慮(lv)多少因(yin)素？手(shou)工巖(yan)(yan)棉板(ban)的容重規格有哪些？

首先，巖(yan)棉是一種以玄武(wu)巖(yan)為主要(yao)原料(liao)生產的保溫材料(liao)。其主要(yao)生產工(gong)藝是將玄武(wu)巖(yan)在高溫下熔化成液體，通過離心工(gong)藝制成一定長度(du)(du)(du)和(he)密(mi)度(du)(du)(du)的輕質纖維，然后固定成型，得到不同堆(dui)密(mi)度(du)(du)(du)和(he)規格的巖(yan)棉產品。

防(fang)(fang)火(huo)手(shou)(shou)(shou)工(gong)巖(yan)(yan)棉(mian)(mian)板(ban)主(zhu)(zhu)要(yao)是(shi)采用(yong)鐘擺法生產的(de)(de)憎水(shui)性(xing)手(shou)(shou)(shou)工(gong)巖(yan)(yan)棉(mian)(mian)板(ban)作為(wei)保溫(wen)層(ceng)材(cai)料(liao)(liao)；手(shou)(shou)(shou)工(gong)巖(yan)(yan)棉(mian)(mian)板(ban)由天然巖(yan)(yan)石(shi)制(zhi)成，如(ru)輝長(chang)巖(yan)(yan)、白(bai)云石(shi)、鋁(lv)釩等作為(wei)主(zhu)(zhu)要(yao)原(yuan)料(liao)(liao)，加(jia)入(ru)適量的(de)(de)粘結(jie)劑(ji)和(he)疏水(shui)劑(ji)后，經高(gao)(gao)溫(wen)熔(rong)融制(zhi)成無機纖維；手(shou)(shou)(shou)工(gong)巖(yan)(yan)棉(mian)(mian)板(ban)是(shi)專為(wei)建(jian)筑外(wai)(wai)墻保溫(wen)薄抹灰系(xi)統(tong)而設(she)計生產的(de)(de)。其(qi)中，外(wai)(wai)墻巖(yan)(yan)棉(mian)(mian)帶還可作為(wei)防(fang)(fang)火(huo)隔離(li)帶，與燃燒性(xing)能達(da)不(bu)到A級的(de)(de)保溫(wen)材(cai)料(liao)(liao)配合使(shi)(shi)用(yong)，提高(gao)(gao)外(wai)(wai)墻防(fang)(fang)火(huo)功(gong)能。手(shou)(shou)(shou)工(gong)巖(yan)(yan)棉(mian)(mian)板(ban)在(zai)電(dian)力、石(shi)油(you)、冶金、造船業(ye)的(de)(de)廣泛(fan)應用(yong)非常方便小口徑管道的(de)(de)建(jian)設(she)。防(fang)(fang)水(shui)巖(yan)(yan)棉(mian)(mian)管也是(shi)防(fang)(fang)潮(chao)的(de)(de)、排溫(wen)、疏水(shui)性(xing)的(de)(de)特殊功(gong)能特別適合在(zai)多雨潮(chao)濕(shi)的(de)(de)環境下使(shi)(shi)用(yong)，吸濕(shi)率為(wei)5%下面，疏水(shui)性(xing)達(da)到99%
