什么是(shi)聚(ju)氨(an)酯(zhi)(zhi)噴涂(tu)(tu)？所謂聚(ju)氨(an)酯(zhi)(zhi)噴涂(tu)(tu)就是(shi)以異酸(suan)酯(zhi)(zhi)和聚(ju)醚為主要原材料(liao)，然后在發泡(pao)劑、催(cui)化劑和阻燃(ran)(ran)劑等(deng)等(deng)多種(zhong)助(zhu)劑的(de)(de)作用之(zhi)下(xia)，通過混合然后再(zai)經高壓(ya)噴涂(tu)(tu)和現場發泡(pao)而(er)成(cheng)的(de)(de)高分子(zi)聚(ju)合物。聚(ju)氨(an)酯(zhi)(zhi)硬泡(pao)體是(shi)一種(zhong)具有(you)良好保溫(wen)(wen)和放水效果的(de)(de)新型合成(cheng)材料(liao)，它具有(you)導熱系(xi)數(shu)(shu)低的(de)(de)優點(dian)。是(shi)目(mu)前各種(zhong)保溫(wen)(wen)材料(liao)中導熱系(xi)數(shu)(shu)比較低的(de)(de)，聚(ju)氨(an)酯(zhi)(zhi)噴涂(tu)(tu)的(de)(de)阻燃(ran)(ran)等(deng)級可以提高到(dao)B1級。

本公司(si)跟您一起(qi)分享聚氨酯噴(pen)涂的相關內容：

硬泡聚(ju)氨酯噴涂施(shi)工關鍵技(ji)術：噴涂施(shi)工中需要解決的關鍵技(ji)術問題主要有以下幾個方(fang)面。

乳白時間和霧(wu)化效(xiao)果(guo)的控制：聚(ju)氨酯泡(pao)(pao)沫的形成需經歷發泡(pao)(pao)和熟化兩個(ge)階段。

從黑(hei)、白料混合開始到(dao)泡沫體積(ji)膨脹(zhang)停(ting)止(zhi)，這個過(guo)程稱為發泡。發泡過(guo)程中，體系釋放出大量的反(fan)應熱酯噴涂工藝(yi)時(shi)，應考慮泡孔的均勻性。泡孔均勻性主要受以下因素影響：

（1）風力

噴(pen)(pen)涂作業時，要(yao)求風速在5m/s以下。風速超過5m/s，將(jiang)吹(chui)失(shi)反(fan)應(ying)產生的熱(re)量(liang)，影響聚(ju)氨酯(zhi)泡沫的快速發泡反(fan)應(ying)，使產品表(biao)面變脆。同時，聚(ju)氨酯(zhi)外墻噴(pen)(pen)涂，由于噴(pen)(pen)涂發泡機將(jiang)原料(liao)混合后，以霧化狀態噴(pen)(pen)出，如風速過大，聚(ju)氨酯(zhi)保溫噴(pen)(pen)涂施(shi)工(gong)，將(jiang)會(hui)吹(chui)走霧化顆粒，增加原料(liao)損耗，污染環境。

（2）環境溫度

聚氨酯發(fa)(fa)泡(pao)(pao)(pao)(pao)(pao)受溫(wen)度(du)(du)(du)的(de)(de)(de)影(ying)(ying)響很大(da)。發(fa)(fa)泡(pao)(pao)(pao)(pao)(pao)依靠熱量而進行，如果沒有熱量，體系(xi)中(zhong)的(de)(de)(de)發(fa)(fa)泡(pao)(pao)(pao)(pao)(pao)劑就無法蒸發(fa)(fa)，從(cong)而無法生(sheng)成泡(pao)(pao)(pao)(pao)(pao)沫(mo)(mo)(mo)(mo)塑(su)料。熱量來自(zi)化(hua)學(xue)(xue)反應(ying)(ying)(ying)產生(sheng)和環(huan)(huan)境提供兩個(ge)方(fang)面。化(hua)學(xue)(xue)反應(ying)(ying)(ying)熱不受外界因素的(de)(de)(de)影(ying)(ying)響，太原聚氨酯噴涂，環(huan)(huan)境提供的(de)(de)(de)熱量則隨環(huan)(huan)境溫(wen)度(du)(du)(du)的(de)(de)(de)變化(hua)而變化(hua)。當環(huan)(huan)境溫(wen)度(du)(du)(du)高(gao)(gao)時，環(huan)(huan)境能給(gei)反應(ying)(ying)(ying)體系(xi)提供熱量，可增加反應(ying)(ying)(ying)速度(du)(du)(du)，縮(suo)短反應(ying)(ying)(ying)時間。表(biao)現(xian)為泡(pao)(pao)(pao)(pao)(pao)沫(mo)(mo)(mo)(mo)發(fa)(fa)泡(pao)(pao)(pao)(pao)(pao)充分(fen)，泡(pao)(pao)(pao)(pao)(pao)沫(mo)(mo)(mo)(mo)表(biao)層(ceng)和芯部密度(du)(du)(du)接近(jin)。當環(huan)(huan)境溫(wen)度(du)(du)(du)低（如18℃以下），部分(fen)反應(ying)(ying)(ying)熱就會(hui)散發(fa)(fa)到(dao)環(huan)(huan)境中(zhong)。熱量的(de)(de)(de)損失(shi)，一方(fang)面造成泡(pao)(pao)(pao)(pao)(pao)沫(mo)(mo)(mo)(mo)熟化(hua)期延長，增大(da)了泡(pao)(pao)(pao)(pao)(pao)沫(mo)(mo)(mo)(mo)成型(xing)收(shou)(shou)縮(suo)率（溫(wen)度(du)(du)(du)越(yue)低，成型(xing)收(shou)(shou)縮(suo)率越(yue)高(gao)(gao)）；另一方(fang)面增加了泡(pao)(pao)(pao)(pao)(pao)沫(mo)(mo)(mo)(mo)材料的(de)(de)(de)用量。實驗表(biao)明：同一發(fa)(fa)泡(pao)(pao)(pao)(pao)(pao)材料，環(huan)(huan)境溫(wen)度(du)(du)(du)15℃時的(de)(de)(de)發(fa)(fa)泡(pao)(pao)(pao)(pao)(pao)體積比25℃時的(de)(de)(de)發(fa)(fa)泡(pao)(pao)(pao)(pao)(pao)體積小25%，從(cong)而提高(gao)(gao)了泡(pao)(pao)(pao)(pao)(pao)沫(mo)(mo)(mo)(mo)的(de)(de)(de)生(sheng)產成本(ben)。
