軟質(zhi)(zhi)纖(xian)(xian)維板(ban)(ban)(ban)(ban)和采用(yong)(yong)濕(shi)(shi)法(fa)(fa)成型干(gan)(gan)(gan)(gan)熱(re)(re)壓(ya)工藝（又稱濕(shi)(shi)干(gan)(gan)(gan)(gan)法(fa)(fa)）的硬質(zhi)(zhi)纖(xian)(xian)維板(ban)(ban)(ban)(ban)，其板(ban)(ban)(ban)(ban)坯都要經過干(gan)(gan)(gan)(gan)燥。干(gan)(gan)(gan)(gan)燥設備有間歇式(shi)和連續式(shi)兩大(da)類。干(gan)(gan)(gan)(gan)燥 1千(qian)克水消耗1.6～1.8千(qian)克蒸(zheng)氣。軟質(zhi)(zhi)纖(xian)(xian)維板(ban)(ban)(ban)(ban)坯干(gan)(gan)(gan)(gan)燥后的終含水率為1～3%。用(yong)(yong)濕(shi)(shi)干(gan)(gan)(gan)(gan)法(fa)(fa)制(zhi)造硬質(zhi)(zhi)纖(xian)(xian)維板(ban)(ban)(ban)(ban)時，板(ban)(ban)(ban)(ban)坯含水率不宜太高(gao)，否則熱(re)(re)壓(ya)時易于發(fa)生鼓(gu)泡在熱(re)(re)壓(ya)過程(cheng)中，天津刨花板(ban)(ban)(ban)(ban)，板(ban)(ban)(ban)(ban)坯的表(biao)層(ceng)與芯層(ceng)會(hui)出現溫(wen)差(cha)(cha)，厚(hou)度較大(da)的中密度板(ban)(ban)(ban)(ban)坯表(biao)芯層(ceng)溫(wen)差(cha)(cha)可達40～60℃，影(ying)響芯層(ceng)樹脂(zhi)固化率。可用(yong)(yong)常規加熱(re)(re)和高(gao)頻加熱(re)(re)消除溫(wen)差(cha)(cha)，并縮(suo)短熱(re)(re)壓(ya)周期。

經加工制成(cheng)的(de)(de)(de)刨(bao)(bao)花(hua)(hua)，其初(chu)含(han)水率大致為40～60%，符(fu)合(he)工藝要(yao)求(qiu)的(de)(de)(de)含(han)水率芯(xin)層為2～4%，刨(bao)(bao)花(hua)(hua)板生產，表層為5～9%。因此(ci)，要(yao)用干(gan)燥機(ji)對(dui)初(chu)含(han)水率不等(deng)的(de)(de)(de)刨(bao)(bao)花(hua)(hua)進行干(gan)燥，使之達到均勻(yun)的(de)(de)(de)終含(han)水率。然后將經過(guo)干(gan)燥的(de)(de)(de)刨(bao)(bao)花(hua)(hua)與液體膠和添加劑混合(he)。通常在刨(bao)(bao)花(hua)(hua)的(de)(de)(de)每平方米表面積上，刨(bao)(bao)花(hua)(hua)板生產廠家，施膠8～12克。膠料由噴(pen)嘴噴(pen)出后成(cheng)為直徑8～35微米的(de)(de)(de)粒子，在刨(bao)(bao)花(hua)(hua)表面上形成(cheng)一個極薄(bo)而均勻(yun)的(de)(de)(de)連續膠層。再將施膠后的(de)(de)(de)刨(bao)(bao)花(hua)(hua)鋪成(cheng)板坯(pi)，其厚度(du)一般為成(cheng)品厚度(du)的(de)(de)(de)10～20倍。即可進行預(yu)壓(ya)和熱(re)壓(ya)處理。預(yu)壓(ya)壓(ya)力(li)為0.2～2兆(zhao)帕，用平板壓(ya)機(ji)或輥筒(tong)壓(ya)機(ji)進行。
