聚氨酯巖棉板厚度： 50mm 75mm  100mm  150mm有效寬度：1000mm芯材容重： 80-120Kg/m導(dǎo)熱系數(shù)： 0.042-0.047W/m.k 表面花紋： 純平/水 波紋/音樂紋/ 浮 雕 /方波  阻燃等級(jí)： A級(jí)

 ◆ 產(chǎn)品優(yōu)勢(shì)

　　聚氨酯巖棉板硬質(zhì)發(fā)泡是目前公認(rèn)好的建筑圍護(hù)防火保溫板材。其導(dǎo)熱系數(shù)低、耐荷性好、抗彎強(qiáng)度高、不吸水、不腐爛、不蟲蛀鼠咬、阻燃性好、耐溫范圍大。利用聚氨酯( PU.PIR )的物理特性及獨(dú)特配方，將聚氨酯發(fā)泡劑均勻噴覆在彩涂鋼板上，使發(fā)泡劑在彩涂鋼板之間發(fā)泡成型成為三層一次性成型的聚氨酯( PU.PIR )彩鋼復(fù)合夾芯板。這種新的輕型建材是彩涂鋼板與聚氨酯的結(jié)合，是輕型建材的發(fā)展方向。

 ◆ 產(chǎn)品特性

　　▲ 密封性能：聚氨酯巖棉板采用了流水線生產(chǎn)工藝，從而利用了聚氨酯產(chǎn)品優(yōu)異的防水性克服了巖棉易吸水潮解的缺點(diǎn)，在物理性能上有效延長了產(chǎn)品的使用壽命。

　　▲ 美觀性能：接口采用歐洲標(biāo)準(zhǔn)進(jìn)行設(shè)計(jì)，外觀圓潤流暢，板面平整美觀，接縫嚴(yán)密，強(qiáng)度可靠，有效防止冷熱橋的產(chǎn)生。

　　▲ 剛度好：聚氨酯巖棉芯材與兩層鋼板粘接成一個(gè)整體，共同工作，再加上屋面板上表面起波壓型，其整體剛度遠(yuǎn)勝于壓型板夾巖棉(玻璃絲棉)的現(xiàn)場(chǎng)復(fù)合板材。夾芯板通過連接件與檁條固定后，大大提高了屋面的整體剛度，加強(qiáng)了屋面整體工作性能。選用巖棉夾芯板，可采用較大檁距，故可節(jié)省檁條用量1/3～2/3。

　　▲ 扣接方式合理：聚氨酯巖棉屋面板采用暗扣連接方式，避免了屋面板接縫漏水的隱患，節(jié)省了配件用量。

　　▲ 固定方法牢固合理：聚氨酯雙側(cè)封巖棉屋面板采用特制M6自攻螺絲與檁條固定，能有效抵抗臺(tái)風(fēng)等外力作用。自攻螺絲設(shè)置在屋面板兩板接縫之間的波峰位置，并采用特殊的防水構(gòu)造，避免產(chǎn)生防水薄弱點(diǎn)。

　　▲ 安裝周期短：聚氨酯巖棉板，由于現(xiàn)場(chǎng)無須二次加工，不僅可保持周圍環(huán)境的整潔，不影響其它工序的正常進(jìn)行，而且可以大大縮短板材的安裝周期，巖棉夾芯板的日平均安裝面積達(dá)600～800m2。

　　▲ 防劃傷保護(hù)：聚氨酯巖棉板在生產(chǎn)時(shí)，可在表面粘貼聚乙烯不干膠保護(hù)膜，以避免運(yùn)輸及安裝過程鋼板表面涂層受到劃傷或磨損。

　　▲ 防火性能優(yōu)異：聚氨酯雙側(cè)封巖棉夾芯板采用的原材料、生產(chǎn)工藝及配方，使它具有很好的防火性能。試驗(yàn)表明，它具有超過1000℃的耐火能力。聚氨酯雙側(cè)封巖棉夾芯板已通過了意大利權(quán)威檢測(cè)機(jī)構(gòu)GIOROANO S.P.A的測(cè)試

　　▲保溫隔熱性好：聚氨酯雙側(cè)封巖棉夾芯板的保溫隔熱性是以巖棉的導(dǎo)熱系數(shù)λ=0.043 W / m2 K為依據(jù)，以相應(yīng)比例的巖棉芯材的厚度計(jì)算求得的。

　　▲隔聲吸音效果顯著：聚氨酯板對(duì)噪聲傳遞有顯著的削減作用，特別適用于有航班通過的地方。另外，采用了巖棉屋面板后，雨水、冰雹對(duì)建筑物的屋面鋼板沖擊而引起室內(nèi)聲響，也明顯減弱。通過測(cè)試，按照ISO 717/82和UNI 8270/7標(biāo)準(zhǔn)，選用密度為120kg/m3巖棉作芯材的夾芯板，隔聲效果可達(dá)到RW=29~30 dB。

　　巖棉夾芯板同時(shí)具有極好的吸音效果，它能吸收較廣頻率范圍內(nèi)的聲音。按照ISO 354/85標(biāo)準(zhǔn)，巖棉夾芯板吸音性能水準(zhǔn)達(dá)到DELTA LA=15.7 dB(A)。

　　聚氨酯板充分發(fā)揮了巖棉芯材的獨(dú)特性能，在防火、保溫隔熱、吸音隔聲等方面有著顯著的功效;同時(shí)又保留了聚氨酯可塑、密閉、高強(qiáng)、不吸水的優(yōu)點(diǎn)。此材料的問世是建筑工程方面一次革命性的改變，使得聚氨酯、巖棉的優(yōu)點(diǎn)得到了充分的融合，屏棄了傳統(tǒng)板材存在的缺點(diǎn)。在某種意義上講，聚氨酯巖棉板與普通巖棉夾芯板不能相提并論。
