隔熱板類別
木材(cai)市場上隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)要(yao)分(fen)好(hao)幾種(zhong)(zhong),分(fen)別是(shi)(shi)石(shi)棉(mian)(mian)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)、防火隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)、真空(kong)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)、擠塑(su)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)、泡(pao)沫(mo)(mo)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)。石(shi)棉(mian)(mian)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)隔熱(re)(re)(re)(re)(re)效果,在(zai)很多消費者都(dou)有真實的(de)(de)(de)(de)(de)感受,所以(yi)(yi)石(shi)棉(mian)(mian)板(ban)(ban)(ban)(ban)(ban)所受到的(de)(de)(de)(de)(de)歡迎程(cheng)度非常高,要(yao)是(shi)(shi)你不(bu)(bu)知(zhi)道隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)有哪幾種(zhong)(zhong)的(de)(de)(de)(de)(de)話(hua),不(bu)(bu)妨(fang)采用石(shi)棉(mian)(mian)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)吧!防火隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban),顧(gu)名(ming)思義(yi)就是(shi)(shi)不(bu)(bu)進可以(yi)(yi)隔熱(re)(re)(re)(re)(re)保(bao)(bao)溫(wen),而且還可以(yi)(yi)防火。而且這也是(shi)(shi)防火隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)最大的(de)(de)(de)(de)(de)一個優勢。 所謂的(de)(de)(de)(de)(de)真空(kong)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban),也就是(shi)(shi)這幾年以(yi)(yi)來最新的(de)(de)(de)(de)(de)一種(zhong)(zhong)環保(bao)(bao)板(ban)(ban)(ban)(ban)(ban)材(cai),屬于(yu)真空(kong)保(bao)(bao)溫(wen)材(cai)料(liao)之中(zhong)的(de)(de)(de)(de)(de)其(qi)一。由填充芯材(cai)以(yi)(yi)及真空(kong)保(bao)(bao)護(hu)表(biao)層,進行復(fu)合(he)而成的(de)(de)(de)(de)(de)一種(zhong)(zhong)真空(kong)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)。擠塑(su)板(ban)(ban)(ban)(ban)(ban)其(qi)實就是(shi)(shi)以(yi)(yi)聚苯(ben)乙烯樹(shu)脂為主要(yao)的(de)(de)(de)(de)(de)原材(cai)料(liao),經(jing)過(guo)特殊的(de)(de)(de)(de)(de)加工技術處理,然后連(lian)續擠出發泡(pao)而成型的(de)(de)(de)(de)(de)一種(zhong)(zhong)新型保(bao)(bao)溫(wen)隔熱(re)(re)(re)(re)(re)材(cai)料(liao)。泡(pao)沫(mo)(mo)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)包括了內(nei)外(wai)兩層泡(pao)沫(mo)(mo)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban),內(nei)外(wai)均為硬質板(ban)(ban)(ban)(ban)(ban)材(cai),內(nei)外(wai)相貼(tie)合(he)。以(yi)(yi)上不(bu)(bu)同(tong)隔熱(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)材(cai)料(liao)有著(zhu)不(bu)(bu)同(tong)的(de)(de)(de)(de)(de)特點,在(zai)選擇的(de)(de)(de)(de)(de)時候還要(yao)謹慎(shen)選擇的(de)(de)(de)(de)(de)好(hao)。
隔熱板材料哪種好
隔(ge)(ge)熱(re)(re)(re)(re)(re)板材(cai)(cai)料(liao)(liao)(liao)分為(wei)多孔材(cai)(cai)料(liao)(liao)(liao)和(he)(he)熱(re)(re)(re)(re)(re)反射材(cai)(cai)料(liao)(liao)(liao)兩類。前(qian)者(zhe)利用(yong)(yong)材(cai)(cai)料(liao)(liao)(liao)本身所(suo)含的(de)(de)(de)孔隙隔(ge)(ge)熱(re)(re)(re)(re)(re),因為(wei)空隙內(nei)的(de)(de)(de)空氣(qi)或惰性(xing)氣(qi)體的(de)(de)(de)導(dao)熱(re)(re)(re)(re)(re)系數(shu)很低,如(ru)泡(pao)沫(mo)材(cai)(cai)料(liao)(liao)(liao)、纖維材(cai)(cai)料(liao)(liao)(liao)等;后一種材(cai)(cai)料(liao)(liao)(liao)具有(you)很高的(de)(de)(de)反射系數(shu),能將熱(re)(re)(re)(re)(re)量反射出去(qu),如(ru)金、銀、鎳、鋁箔(bo)或鍍金屬的(de)(de)(de)聚酯(zhi)、聚酰(xian)亞胺薄膜(mo)等。航(hang)(hang)空航(hang)(hang)天(tian)工業對所(suo)用(yong)(yong)隔(ge)(ge)熱(re)(re)(re)(re)(re)材(cai)(cai)料(liao)(liao)(liao)的(de)(de)(de)重量和(he)(he)體積(ji)要求(qiu)較為(wei)苛(ke)刻(ke),往往還(huan)要求(qiu)它兼有(you)隔(ge)(ge)音、減振、防(fang)腐(fu)蝕(shi)等性(xing)能。各(ge)種飛行器對隔(ge)(ge)熱(re)(re)(re)(re)(re)材(cai)(cai)料(liao)(liao)(liao)的(de)(de)(de)需要不盡相同(tong)。飛機座艙(cang)和(he)(he)駕駛艙(cang)內(nei)常用(yong)(yong)泡(pao)沫(mo)塑(su)料(liao)(liao)(liao)、超細(xi)玻璃棉(mian)、高硅氧(yang)棉(mian)來隔(ge)(ge)熱(re)(re)(re)(re)(re)。導(dao)彈(dan)頭部用(yong)(yong)的(de)(de)(de)隔(ge)(ge)熱(re)(re)(re)(re)(re)材(cai)(cai)料(liao)(liao)(liao)早期是(shi)酚醛泡(pao)沫(mo)塑(su)料(liao)(liao)(liao),隨著(zhu)耐溫(wen)性(xing)好(hao)的(de)(de)(de)聚氨(an)酯(zhi)泡(pao)沫(mo)塑(su)料(liao)(liao)(liao)的(de)(de)(de)應用(yong)(yong),又(you)將單一的(de)(de)(de)隔(ge)(ge)熱(re)(re)(re)(re)(re)材(cai)(cai)料(liao)(liao)(liao)發展為(wei)夾(jia)層(ceng)(ceng)(ceng)結構。導(dao)彈(dan)儀器艙(cang)的(de)(de)(de)隔(ge)(ge)熱(re)(re)(re)(re)(re)方(fang)式是(shi)在(zai)(zai)艙(cang)體外(wai)蒙皮(pi)上涂(tu)一層(ceng)(ceng)(ceng)數(shu)毫米厚的(de)(de)(de)發泡(pao)涂(tu)料(liao)(liao)(liao),在(zai)(zai)常溫(wen)下作(zuo)為(wei)防(fang)腐(fu)蝕(shi)涂(tu)層(ceng)(ceng)(ceng),當氣(qi)動加熱(re)(re)(re)(re)(re)達到(dao)200°C以上時,便均勻發泡(pao)而起隔(ge)(ge)熱(re)(re)(re)(re)(re)作(zuo)用(yong)(yong)。人造地球衛星是(shi)在(zai)(zai)高溫(wen)、低溫(wen)交變(bian)的(de)(de)(de)環境(jing)中運動,須使用(yong)(yong)高反射性(xing)能的(de)(de)(de)多層(ceng)(ceng)(ceng)隔(ge)(ge)熱(re)(re)(re)(re)(re)材(cai)(cai)料(liao)(liao)(liao),一般是(shi)由幾十(shi)層(ceng)(ceng)(ceng)鍍鋁薄膜(mo)、鍍鋁聚酯(zhi)薄膜(mo)、鍍鋁聚酰(xian)亞胺薄膜(mo)組成(cheng)。另外(wai),表面隔(ge)(ge)熱(re)(re)(re)(re)(re)瓦的(de)(de)(de)研制成(cheng)功解決了航(hang)(hang)天(tian)飛機的(de)(de)(de)隔(ge)(ge)熱(re)(re)(re)(re)(re)問題,同(tong)時也標志著(zhu)隔(ge)(ge)熱(re)(re)(re)(re)(re)材(cai)(cai)料(liao)(liao)(liao)發展的(de)(de)(de)更高水平。
