做激光刀模(mo)所(suo)用(yong)的胶合木板都有哪些？

胶(jiao)(jiao)合(he)木(mu)板是(shi)原木(mu)浸水(shui)后通(tong)过卷刨(bao)切割成(cheng)按(an)尺寸要求的连续薄片(pian)板，用机器降低水(shui)分(fen)到适当(dang)标准值，再用尿素甲醛胶(jiao)(jiao)水(shui)以十字交叉(cha)方式多层粘(zhan)结而成(cheng)的板材。粘(zhan)结前的薄片(pian)板应按(an)标准分(fen)好等(deng)级且进行过预(yu)压(ya)处理(li)。

胶合(he)木(mu)(mu)板(ban)的(de)构成：桦(hua)木(mu)(mu)、针叶木(mu)(mu)、杨木(mu)(mu)、杂木(mu)(mu)，准(zhun)确地说，作为激(ji)光刀模常用的(de)标(biao)准(zhun)胶合(he)木(mu)(mu)板(ban)应由(you)桦(hua)木(mu)(mu)与针叶木(mu)(mu)组(zu)成，而现(xian)今(jin)市(shi)场上(shang)的(de)杨木(mu)(mu)板(ban)、杂木(mu)(mu)板(ban)、桦(hua)面杨芯板(ban)、桦(hua)面杂芯板(ban)等板(ban)的(de)适应激(ji)光切割性与机械性能(neng)（弹性、应力(li)等）均(jun)难适应作为高要(yao)求(qiu)包装产品的(de)激(ji)光刀模板(ban)的(de)要(yao)求(qiu)。

桦木(mu)(mu)板的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)木(mu)(mu)纹纹路较(jiao)轻、较(jiao)美(mei)观(guan)，芬兰胶合(he)木(mu)(mu)板行业(ye)将它分为(wei)(wei)五(wu)个(ge)(ge)等级(ji)(ji)(ji)(ji)(ji)，由高(gao)(gao)(gao)到(dao)低(di)依次是A、B、S、BB、WG，A级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)可(ke)直接(jie)上(shang)清(qing)(qing)漆(qi)的(de)高(gao)(gao)(gao)质(zhi)(zhi)量表(biao)面(mian)(mian)(mian)(mian)(mian)；B级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)适用(yong)(yong)高(gao)(gao)(gao)质(zhi)(zhi)量涂(tu)(tu)料(liao)、染色、清(qing)(qing)漆(qi)的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)；S级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)适用(yong)(yong)高(gao)(gao)(gao)质(zhi)(zhi)量油(you)(you)漆(qi)、覆膜的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)；BB级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)适用(yong)(yong)标(biao)准内部油(you)(you)漆(qi)的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)；WG级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)无须要(yao)(yao)求的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)。针(zhen)叶木(mu)(mu)薄片板的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)木(mu)(mu)纹纹路较(jiao)重，芬兰胶合(he)木(mu)(mu)板行业(ye)将它也分为(wei)(wei)五(wu)个(ge)(ge)等级(ji)(ji)(ji)(ji)(ji)，由高(gao)(gao)(gao)到(dao)低(di)依次是E、EI、EⅡ、EⅧ、EIV，E级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)可(ke)直接(jie)上(shang)清(qing)(qing)漆(qi)的(de)高(gao)(gao)(gao)质(zhi)(zhi)量表(biao)面(mian)(mian)(mian)(mian)(mian)；EEI级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)适用(yong)(yong)高(gao)(gao)(gao)质(zhi)(zhi)量涂(tu)(tu)料(liao)、染色、清(qing)(qing)漆(qi)的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)；EE II级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)适用(yong)(yong)普通油(you)(you)漆(qi)、对(dui)表(biao)面(mian)(mian)(mian)(mian)(mian)要(yao)(yao)求不高(gao)(gao)(gao)的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)；EEⅢ级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)适用(yong)(yong)于对(dui)表(biao)面(mian)(mian)(mian)(mian)(mian)要(yao)(yao)求很低(di)的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)；EEIV级(ji)(ji)(ji)(ji)(ji)为(wei)(wei)适用(yong)(yong)于对(dui)表(biao)面(mian)(mian)(mian)(mian)(mian)没要(yao)(yao)求的(de)表(biao)面(mian)(mian)(mian)(mian)(mian)。

以(yi)(yi)适(shi)合(he)用作高档激光(guang)刀(dao)模板(ban)的芬(fen)兰(lan)胶合(he)木(mu)(mu)板(ban)为(wei)例，该(gai)类别芬(fen)兰(lan)板(ban)的基版为(wei)标准结构的桦(hua)(hua)木(mu)(mu)板(ban)，内用尿素(su)甲醛胶水(shui)以(yi)(yi)十(shi)字交叉方式粘结，以(yi)(yi)经过(guo)砂光(guang)处(chu)理的S级和BB级桦(hua)(hua)木(mu)(mu)薄板(ban)为(wei)表面，正反两(liang)面均施无色(se)或绿色(se)透明UV固化漆，边缘以(yi)(yi)透明丙烯(xi)酸涂料封边。由(you)于芬(fen)兰(lan)板(ban)生产工艺中(zhong)有去疤节处(chu)理及厚度公差控制严格特(te)点，故高档激光(guang)刀(dao)模多采用，以(yi)(yi)利于刀(dao)线(xian)的装嵌(qian)和回弹胶弹力的保(bao)证。
