隔熱板類別
木材(cai)市場(chang)上隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)要(yao)(yao)分(fen)好幾種,分(fen)別是(shi)石(shi)棉隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)、防火(huo)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)、真(zhen)(zhen)空(kong)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)、擠(ji)塑隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)、泡(pao)沫(mo)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)。石(shi)棉板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)隔(ge)(ge)(ge)(ge)(ge)熱效(xiao)果(guo),在很多消費者都有(you)(you)真(zhen)(zhen)實的(de)(de)(de)感受(shou)(shou),所以(yi)石(shi)棉板(ban)(ban)(ban)(ban)(ban)所受(shou)(shou)到的(de)(de)(de)歡迎程度非常高,要(yao)(yao)是(shi)你(ni)不(bu)(bu)知道隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)有(you)(you)哪幾種的(de)(de)(de)話,不(bu)(bu)妨采用石(shi)棉隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)吧!防火(huo)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban),顧名(ming)思(si)義就是(shi)不(bu)(bu)進可(ke)以(yi)隔(ge)(ge)(ge)(ge)(ge)熱保(bao)溫,而且還(huan)可(ke)以(yi)防火(huo)。而且這(zhe)也是(shi)防火(huo)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)最大(da)的(de)(de)(de)一個優勢。 所謂(wei)的(de)(de)(de)真(zhen)(zhen)空(kong)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban),也就是(shi)這(zhe)幾年以(yi)來(lai)最新的(de)(de)(de)一種環保(bao)板(ban)(ban)(ban)(ban)(ban)材(cai),屬于真(zhen)(zhen)空(kong)保(bao)溫材(cai)料(liao)之中的(de)(de)(de)其一。由填充芯(xin)材(cai)以(yi)及真(zhen)(zhen)空(kong)保(bao)護表層(ceng),進行復(fu)合而成(cheng)(cheng)的(de)(de)(de)一種真(zhen)(zhen)空(kong)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)。擠(ji)塑板(ban)(ban)(ban)(ban)(ban)其實就是(shi)以(yi)聚苯乙(yi)烯樹脂為(wei)主(zhu)要(yao)(yao)的(de)(de)(de)原材(cai)料(liao),經過特殊的(de)(de)(de)加工技(ji)術(shu)處(chu)理,然后(hou)連續擠(ji)出發泡(pao)而成(cheng)(cheng)型(xing)的(de)(de)(de)一種新型(xing)保(bao)溫隔(ge)(ge)(ge)(ge)(ge)熱材(cai)料(liao)。泡(pao)沫(mo)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)包括了內(nei)外兩層(ceng)泡(pao)沫(mo)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban),內(nei)外均為(wei)硬質(zhi)板(ban)(ban)(ban)(ban)(ban)材(cai),內(nei)外相貼(tie)合。以(yi)上不(bu)(bu)同(tong)隔(ge)(ge)(ge)(ge)(ge)熱板(ban)(ban)(ban)(ban)(ban)材(cai)料(liao)有(you)(you)著不(bu)(bu)同(tong)的(de)(de)(de)特點(dian),在選擇(ze)的(de)(de)(de)時候(hou)還(huan)要(yao)(yao)謹慎選擇(ze)的(de)(de)(de)好。
隔熱板材料哪種好
隔熱(re)(re)(re)(re)(re)板材(cai)(cai)(cai)(cai)料(liao)分為(wei)(wei)多孔材(cai)(cai)(cai)(cai)料(liao)和(he)熱(re)(re)(re)(re)(re)反(fan)射材(cai)(cai)(cai)(cai)料(liao)兩類。前(qian)者利(li)用(yong)(yong)(yong)材(cai)(cai)(cai)(cai)料(liao)本身所(suo)含的(de)孔隙(xi)(xi)隔熱(re)(re)(re)(re)(re),因為(wei)(wei)空隙(xi)(xi)內的(de)空氣(qi)或惰性(xing)氣(qi)體的(de)導(dao)熱(re)(re)(re)(re)(re)系(xi)數(shu)很低,如泡沫(mo)(mo)材(cai)(cai)(cai)(cai)料(liao)、纖維(wei)材(cai)(cai)(cai)(cai)料(liao)等;后一種(zhong)(zhong)材(cai)(cai)(cai)(cai)料(liao)具有(you)很高(gao)的(de)反(fan)射系(xi)數(shu),能將(jiang)熱(re)(re)(re)(re)(re)量反(fan)射出去,如金、銀、鎳、鋁(lv)箔或鍍(du)金屬的(de)聚酯、聚酰(xian)亞(ya)胺薄(bo)膜等。航空航天(tian)(tian)工業對所(suo)用(yong)(yong)(yong)隔熱(re)(re)(re)(re)(re)材(cai)(cai)(cai)(cai)料(liao)的(de)重(zhong)量和(he)體積要求較為(wei)(wei)苛刻,往往還要求它兼有(you)隔音、減振(zhen)、防(fang)腐蝕等性(xing)能。各種(zhong)(zhong)飛行器(qi)對隔熱(re)(re)(re)(re)(re)材(cai)(cai)(cai)(cai)料(liao)的(de)需要不盡相同(tong)。飛機座艙(cang)和(he)駕駛艙(cang)內常用(yong)(yong)(yong)泡沫(mo)(mo)塑(su)(su)料(liao)、超(chao)細玻璃棉(mian)、高(gao)硅(gui)氧棉(mian)來隔熱(re)(re)(re)(re)(re)。導(dao)彈頭部用(yong)(yong)(yong)的(de)隔熱(re)(re)(re)(re)(re)材(cai)(cai)(cai)(cai)料(liao)早(zao)期是(shi)酚醛泡沫(mo)(mo)塑(su)(su)料(liao),隨著(zhu)耐溫(wen)性(xing)好的(de)聚氨酯泡沫(mo)(mo)塑(su)(su)料(liao)的(de)應用(yong)(yong)(yong),又將(jiang)單一的(de)隔熱(re)(re)(re)(re)(re)材(cai)(cai)(cai)(cai)料(liao)發展(zhan)為(wei)(wei)夾(jia)層結構。導(dao)彈儀(yi)器(qi)艙(cang)的(de)隔熱(re)(re)(re)(re)(re)方式是(shi)在(zai)(zai)艙(cang)體外(wai)蒙(meng)皮(pi)上涂一層數(shu)毫米厚(hou)的(de)發泡涂料(liao),在(zai)(zai)常溫(wen)下作為(wei)(wei)防(fang)腐蝕涂層,當氣(qi)動(dong)加熱(re)(re)(re)(re)(re)達到200°C以上時,便均勻發泡而(er)起隔熱(re)(re)(re)(re)(re)作用(yong)(yong)(yong)。人造地球(qiu)衛星是(shi)在(zai)(zai)高(gao)溫(wen)、低溫(wen)交(jiao)變的(de)環境中(zhong)運動(dong),須使用(yong)(yong)(yong)高(gao)反(fan)射性(xing)能的(de)多層隔熱(re)(re)(re)(re)(re)材(cai)(cai)(cai)(cai)料(liao),一般是(shi)由幾(ji)十層鍍(du)鋁(lv)薄(bo)膜、鍍(du)鋁(lv)聚酯薄(bo)膜、鍍(du)鋁(lv)聚酰(xian)亞(ya)胺薄(bo)膜組成(cheng)。另外(wai),表面隔熱(re)(re)(re)(re)(re)瓦的(de)研制成(cheng)功解決了(le)航天(tian)(tian)飛機的(de)隔熱(re)(re)(re)(re)(re)問題(ti),同(tong)時也標志(zhi)著(zhu)隔熱(re)(re)(re)(re)(re)材(cai)(cai)(cai)(cai)料(liao)發展(zhan)的(de)更(geng)高(gao)水平。
