【生態家(jia)具(ju)板(ban)設(she)備(bei)廠家(jia)介(jie)紹】膠合(he)板(ban)的生產流程，膠(jiao)(jiao)合板(ban)(ban)(ban)(ban)是由木段旋切(qie)成(cheng)單板(ban)(ban)(ban)(ban)或(huo)(huo)(huo)由木方(fang)(fang)刨切(qie)成(cheng)薄木，再(zai)用膠(jiao)(jiao)粘劑膠(jiao)(jiao)合而成(cheng)的(de)三層(ceng)或(huo)(huo)(huo)多層(ceng)的(de)板(ban)(ban)(ban)(ban)狀材料(liao)，通常(chang)(chang)用奇數層(ceng)單板(ban)(ban)(ban)(ban)，并使相(xiang)(xiang)鄰層(ceng)單板(ban)(ban)(ban)(ban)的(de)纖(xian)維方(fang)(fang)向(xiang)(xiang)互相(xiang)(xiang)垂直(zhi)膠(jiao)(jiao)合而成(cheng)。一組(zu)單板(ban)(ban)(ban)(ban)通常(chang)(chang)按相(xiang)(xiang)鄰層(ceng)木紋方(fang)(fang)向(xiang)(xiang)互相(xiang)(xiang)垂直(zhi)組(zu)坯(pi)膠(jiao)(jiao)合而成(cheng)，通常(chang)(chang)其表板(ban)(ban)(ban)(ban)和(he)(he)內層(ceng)板(ban)(ban)(ban)(ban)對稱地配置在中心(xin)層(ceng)或(huo)(huo)(huo)板(ban)(ban)(ban)(ban)芯的(de)兩側。用涂膠(jiao)(jiao)后的(de)單板(ban)(ban)(ban)(ban)按木紋方(fang)(fang)向(xiang)(xiang)縱橫(heng)交(jiao)錯配成(cheng)的(de)板(ban)(ban)(ban)(ban)坯(pi)，在加(jia)(jia)熱或(huo)(huo)(huo)不加(jia)(jia)熱的(de)條件下壓制而成(cheng)。縱橫(heng)方(fang)(fang)向(xiang)(xiang)的(de)物理、機械性質差異(yi)較(jiao)小。常(chang)(chang)用的(de)膠(jiao)(jiao)合板(ban)(ban)(ban)(ban)類(lei)型有三合板(ban)(ban)(ban)(ban)、五合板(ban)(ban)(ban)(ban)等。普通膠(jiao)(jiao)合板(ban)(ban)(ban)(ban)使用過程(cheng)中，會使用大量的(de)膠(jiao)(jiao)黏劑，如以尿素和(he)(he)甲(jia)醛(quan)為主要(yao)原(yuan)(yuan)材料(liao)的(de)脲醛(quan)樹脂(zhi)膠(jiao)(jiao)，以三聚氰胺和(he)(he)甲(jia)醛(quan)為主要(yao)原(yuan)(yuan)材料(liao)的(de)三聚氰胺膠(jiao)(jiao)，以苯酚和(he)(he)甲(jia)醛(quan)為主要(yao)原(yuan)(yuan)材料(liao)的(de)酚醛(quan)膠(jiao)(jiao)，這(zhe)些膠(jiao)(jiao)黏劑都(dou)存在甲(jia)醛(quan)釋放的(de)問題(ti)。
