林森手工玻鎂巖棉板的老化期有多長？林森手工玻鎂巖棉板這個理(li)論認為巖棉纖維(wei)是一種(zhong)無機纖維(wei)，不(bu)(bu)會老(lao)(lao)化。在(zai)實際的(de)(de)(de)巖棉產(chan)(chan)品中(zhong)(zhong)，除(chu)了巖棉之(zhi)外，還添加了一定量的(de)(de)(de)酚醛(quan)樹(shu)脂和(he)防(fang)(fang)水(shui)劑(ji)。這類有(you)機物在(zai)使用(yong)中(zhong)(zhong)會出現(xian)不(bu)(bu)同(tong)程度的(de)(de)(de)老(lao)(lao)化，導致巖棉產(chan)(chan)品使用(yong)功(gong)能的(de)(de)(de)喪失——老(lao)(lao)化。棉制(zhi)品疏水(shui)劑(ji)的(de)(de)(de)老(lao)(lao)化是由(you)于疏水(shui)膜被破壞，降低(di)了其疏水(shui)率。酚醛(quan)樹(shu)脂的(de)(de)(de)老(lao)(lao)化現(xian)象(xiang)是粉化，會明(ming)顯降低(di)產(chan)(chan)品的(de)(de)(de)強度。然(ran)而，目(mu)前(qian)沒有(you)公認的(de)(de)(de)不(bu)(bu)同(tong)酚醛(quan)樹(shu)脂和(he)防(fang)(fang)水(shui)劑(ji)配方的(de)(de)(de)老(lao)(lao)化時間。

林(lin)森(sen)(sen)手(shou)工(gong)玻(bo)鎂(mei)(mei)巖(yan)(yan)棉(mian)(mian)板(ban)(ban)產品為什么要防潮？林(lin)森(sen)(sen)手(shou)工(gong)玻(bo)鎂(mei)(mei)巖(yan)(yan)棉(mian)(mian)板(ban)(ban)是一種(zhong)高吸(xi)水性(xing)的(de)無機(ji)纖(xian)維棉(mian)(mian)。林(lin)森(sen)(sen)手(shou)工(gong)玻(bo)鎂(mei)(mei)巖(yan)(yan)棉(mian)(mian)板(ban)(ban)被水浸(jin)泡后，導(dao)熱(re)系數大(da)大(da)增加(jia)，機(ji)械強度明顯下降，尺寸明顯變(bian)化(hua)，保溫功(gong)能完全喪失，失去使(shi)用(yong)功(gong)能。因此，林(lin)森(sen)(sen)手(shou)工(gong)玻(bo)鎂(mei)(mei)巖(yan)(yan)棉(mian)(mian)板(ban)(ban)產品必須采取防潮措施，以(yi)具有(you)良好的(de)保溫性(xing)能、機(ji)械強度和較小(xiao)的(de)尺寸變(bian)化(hua)率(lv)。一般來說，為了提高林(lin)森(sen)(sen)手(shou)工(gong)玻(bo)鎂(mei)(mei)巖(yan)(yan)棉(mian)(mian)板(ban)(ban)的(de)防潮性(xing)能，在巖(yan)(yan)棉(mian)(mian)纖(xian)維中添加(jia)防水劑，使(shi)林(lin)森(sen)(sen)手(shou)工(gong)玻(bo)鎂(mei)(mei)巖(yan)(yan)棉(mian)(mian)板(ban)(ban)的(de)加(jia)濕率(lv)達到98%以(yi)上，質量(liang)吸(xi)濕率(lv)小(xiao)于(yu)5-10%。

隔熱技術(shu)應(ying)用于(yu)建筑物(wu)以(yi)保護結構(gou)墻。在(zai)眾多(duo)保溫(wen)材(cai)料市(shi)場中，林(lin)森(sen)手工(gong)玻鎂巖棉板(ban)(ban)脫穎而(er)出。如今，保溫(wen)節能(neng)的趨勢不可逆轉(zhuan)選擇(ze)保溫(wen)材(cai)料要考慮多(duo)少因素？林(lin)森(sen)手工(gong)玻鎂巖棉板(ban)(ban)的容重規格(ge)有哪些？

首先(xian)，巖(yan)(yan)棉是一種以玄(xuan)武巖(yan)(yan)為(wei)主要原料生產的保溫材(cai)料。其主要生產工藝是將玄(xuan)武巖(yan)(yan)在高溫下熔化(hua)成液(ye)體，通過離心工藝制成一定長度(du)和(he)密度(du)的輕質(zhi)纖(xian)維，然后固定成型，得到不(bu)同堆密度(du)和(he)規格的巖(yan)(yan)棉產品。

防(fang)火林(lin)(lin)森(sen)(sen)手(shou)工(gong)(gong)(gong)玻鎂(mei)(mei)巖(yan)(yan)(yan)棉板(ban)主要是(shi)(shi)采用鐘擺法生產的(de)(de)憎(zeng)水(shui)性林(lin)(lin)森(sen)(sen)手(shou)工(gong)(gong)(gong)玻鎂(mei)(mei)巖(yan)(yan)(yan)棉板(ban)作為(wei)保溫層材(cai)料；林(lin)(lin)森(sen)(sen)手(shou)工(gong)(gong)(gong)玻鎂(mei)(mei)巖(yan)(yan)(yan)棉板(ban)由天然巖(yan)(yan)(yan)石制(zhi)成(cheng)，如輝(hui)長(chang)巖(yan)(yan)(yan)、白云石、鋁釩等作為(wei)主要原料，加(jia)入適(shi)量的(de)(de)粘結(jie)劑(ji)(ji)和疏水(shui)劑(ji)(ji)后，經高溫熔融制(zhi)成(cheng)無機(ji)纖維(wei)；林(lin)(lin)森(sen)(sen)手(shou)工(gong)(gong)(gong)玻鎂(mei)(mei)巖(yan)(yan)(yan)棉板(ban)是(shi)(shi)專為(wei)建(jian)(jian)筑外(wai)墻保溫薄抹灰系統而設計生產的(de)(de)。其中，外(wai)墻巖(yan)(yan)(yan)棉帶(dai)還(huan)可作為(wei)防(fang)火隔離帶(dai)，與燃燒性能(neng)達不到(dao)A級的(de)(de)保溫材(cai)料配(pei)合使用，提高外(wai)墻防(fang)火功能(neng)。林(lin)(lin)森(sen)(sen)手(shou)工(gong)(gong)(gong)玻鎂(mei)(mei)巖(yan)(yan)(yan)棉板(ban)在電力、石油、冶(ye)金、造船業(ye)的(de)(de)廣泛應用非常方便小(xiao)口徑管道的(de)(de)建(jian)(jian)設。防(fang)水(shui)巖(yan)(yan)(yan)棉管也是(shi)(shi)防(fang)潮的(de)(de)、排溫、疏水(shui)性的(de)(de)特殊(shu)功能(neng)特別適(shi)合在多雨潮濕的(de)(de)環(huan)境下(xia)使用，吸濕率為(wei)5%下(xia)面，疏水(shui)性達到(dao)99%

林(lin)(lin)森手工(gong)玻(bo)(bo)(bo)鎂巖棉板的(de)容(rong)重(zhong)一般為80-120kg/立方(fang)米，一般防火林(lin)(lin)森手工(gong)玻(bo)(bo)(bo)鎂巖棉板的(de)容(rong)重(zhong)不(bu)小于120kg/立方(fang)米，當然不(bu)同(tong)(tong)的(de)建(jian)筑需要不(bu)同(tong)(tong)的(de)厚度。林(lin)(lin)森手工(gong)玻(bo)(bo)(bo)鎂巖棉板疏水(shui)性高，能適應南(nan)北溫(wen)差(cha)。同(tong)(tong)時(shi)，不(bu)同(tong)(tong)的(de)石(shi)材裝飾(shi)面，價(jia)格(ge)(ge)和施工(gong)成(cheng)本(ben)也不(bu)同(tong)(tong)。另外(wai)，考(kao)慮長途運(yun)輸、人力(li)物力(li)的(de)損耗等因素也影(ying)響林(lin)(lin)森手工(gong)玻(bo)(bo)(bo)鎂巖棉板的(de)綜合價(jia)格(ge)(ge)。在選擇林(lin)(lin)森手工(gong)玻(bo)(bo)(bo)鎂巖棉板時(shi)，你(ni)應該根(gen)據自己的(de)需要、篩選應用場(chang)景，綜合比較不(bu)同(tong)(tong)堆密度規格(ge)(ge)，評估后下(xia)單。
