其實巖棉復合(he)板在(zai)使(shi)用中(zhong)也會遇到一些誤(wu)區，如(ru)何才能避免這樣(yang)的(de)問題放生呢，下面小編就來具體的(de)說明(ming)下。

  巖(yan)(yan)棉(mian)復合板(ban)的價格與密度(du)和厚度(du)有關，密度(du)140KG/m3以(yi)上(shang)屬于高密度(du)巖(yan)(yan)棉(mian)板(ban)，以(yi)下(xia)為低密度(du)巖(yan)(yan)棉(mian)板(ban)，很多施工單位在采購(gou)巖(yan)(yan)棉(mian)板(ban)的時(shi)候都選擇了(le)低密度(du)巖(yan)(yan)棉(mian)板(ban)(80~120KG/m3)，結果(guo)施工的時(shi)候，因為巖(yan)(yan)棉(mian)板(ban)太軟，上(shang)面不得(de)加一層(ceng)剛(gang)(gang)性(xing)混(hun)凝(ning)土層(ceng)(單層(ceng)雙向配筋Φ8@200)，則增(zeng)加的剛(gang)(gang)性(xing)混(hun)凝(ning)土層(ceng)每平方米至(zhi)少增(zeng)加材料費用也不低，再加上(shang)做一層(ceng)剛(gang)(gang)性(xing)混(hun)凝(ning)土層(ceng)的人工費、工期等等，則造價比直接采用高密度(du)巖(yan)(yan)棉(mian)板(ban)高出了(le)一倍以(yi)上(shang)，反而得(de)不償失(shi)。

  從設(she)計角度來(lai)說，巖棉(mian)復合板(ban)是種新型的(de)保溫材料(liao)，很(hen)多建筑設(she)計師都不太了(le)解(jie)這種材料(liao)的(de)性能，設(she)計圖紙上只是表達(da)了(le)巖棉(mian)板(ban)的(de)厚度及(ji)導熱系數(shu)，給保溫材料(liao)公司(si)留下了(le)很(hen)大的(de)操作空間，也(ye)給施工(gong)單位(wei)帶來(lai)了(le)不少的(de)麻煩。一般來(lai)說，巖棉(mian)板(ban)還應(ying)增加抗壓強度及(ji)憎水率的(de)要(yao)求。
