熱熔膠行(xing)業的新技(ji)術(shu)及發展(zhan)趨勢

1.低壓注塑熱熔膠

低(di)(di)(di)(di)壓注塑熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)突破了一般傳統熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)的(de)使用(yong)極限。其(qi)(qi)正(zheng)常操(cao)作(zuo)溫(wen)(wen)度(du)僅為110℃~130℃，低(di)(di)(di)(di)壓注塑熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)比傳統熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)的(de)使用(yong)溫(wen)(wen)度(du)低(di)(di)(di)(di)了30℃以上。低(di)(di)(di)(di)壓注塑熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)和傳統熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)相比具有明顯低(di)(di)(di)(di)的(de)粘度(du)值，保(bao)證在低(di)(di)(di)(di)溫(wen)(wen)操(cao)作(zuo)條件下(xia)滿(man)足各項涂布工藝要(yao)求。低(di)(di)(di)(di)壓注塑熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)所(suo)帶(dai)來的(de)直(zhi)接好處是(shi)節省電(dian)費(fei)(fei)和機(ji)器維(wei)修保(bao)養費(fei)(fei)用(yong)。大(da)量實際應用(yong)顯示，同樣的(de)熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)機(ji)，使用(yong)低(di)(di)(di)(di)壓注塑熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)可(ke)為客戶節省約(yue)15%的(de)電(dian)費(fei)(fei)。而由于低(di)(di)(di)(di)壓注塑熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)在其(qi)(qi)110℃~130℃的(de)正(zheng)常操(cao)作(zuo)溫(wen)(wen)度(du)下(xia)幾乎完全沒有結(jie)皮、積碳等老化現(xian)象，使得(de)機(ji)器的(de)維(wei)修保(bao)養費(fei)(fei)用(yong)大(da)大(da)降低(di)(di)(di)(di)。更(geng)為重要(yao)的(de)是(shi)，低(di)(di)(di)(di)壓注塑熱(re)(re)(re)熔(rong)(rong)膠(jiao)(jiao)(jiao)不會燙傷PE膜(mo)。

傳統熱(re)熔(rong)膠(jiao)普遍(bian)具有(you)疏水(shui)(shui)性，親(qin)水(shui)(shui)性熱(re)熔(rong)膠(jiao)通(tong)過特(te)別的配方使(shi)之具有(you)親(qin)水(shui)(shui)性，每一種親(qin)水(shui)(shui)性熱(re)熔(rong)膠(jiao)的應用都(dou)能賦予產(chan)(chan)品更(geng)高的附(fu)加值，使(shi)產(chan)(chan)品生產(chan)(chan)廠家在當前競爭十分激烈的市場上，有(you)效地進行產(chan)(chan)品差(cha)異化，從而最終贏得消費者。
