激光刀模常用木板(圖1)

做激光刀模所(suo)用的(de)膠合(he)木(mu)板都有(you)哪(na)些(xie)?

膠合木(mu)(mu)板是原木(mu)(mu)浸(jin)水后通(tong)過(guo)卷(juan)刨切割成按(an)尺寸(cun)要求的連(lian)續薄(bo)(bo)片板,用機(ji)器降低水分(fen)到適當(dang)標準值,再用尿(niao)素甲醛膠水以十字交(jiao)叉(cha)方式多層粘結而成的板材。粘結前(qian)的薄(bo)(bo)片板應(ying)按(an)標準分(fen)好等(deng)級且(qie)進(jin)行過(guo)預壓處理。

激光刀模板

做激光(guang)刀模常用(yong)的有:國(guo)產楊(yang)木(mu)膠(jiao)合(he)板,國(guo)產樺木(mu)膠(jiao)合(he)板,進口芬蘭膠(jiao)合(he)板等。

膠(jiao)(jiao)合(he)木板的(de)(de)構成:樺木、針葉木、楊(yang)木、雜木,準確地說,作為激(ji)光(guang)刀模常用的(de)(de)標(biao)準膠(jiao)(jiao)合(he)木板應(ying)由(you)樺木與針葉木組成,而現今市(shi)場(chang)上的(de)(de)楊(yang)木板、雜木板、樺面楊(yang)芯板、樺面雜芯板等板的(de)(de)適應(ying)激(ji)光(guang)切割性與機械性能(彈性、應(ying)力(li)等)均難適應(ying)作為高要(yao)求包裝(zhuang)產(chan)品的(de)(de)激(ji)光(guang)刀模板的(de)(de)要(yao)求。

膠合木板

樺木(mu)板(ban)(ban)(ban)的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)木(mu)紋紋路較輕、較美觀,芬(fen)蘭(lan)膠合木(mu)板(ban)(ban)(ban)行業將它分(fen)為(wei)(wei)(wei)(wei)五個等級(ji)(ji),由高到(dao)低(di)依(yi)次(ci)是(shi)A、B、S、BB、WG,A級(ji)(ji)為(wei)(wei)(wei)(wei)可直(zhi)接上清漆的高質(zhi)(zhi)量表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);B級(ji)(ji)為(wei)(wei)(wei)(wei)適用(yong)(yong)高質(zhi)(zhi)量涂(tu)料、染色、清漆的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);S級(ji)(ji)為(wei)(wei)(wei)(wei)適用(yong)(yong)高質(zhi)(zhi)量油(you)漆、覆膜的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);BB級(ji)(ji)為(wei)(wei)(wei)(wei)適用(yong)(yong)標準內部油(you)漆的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);WG級(ji)(ji)為(wei)(wei)(wei)(wei)無須要(yao)(yao)(yao)(yao)求(qiu)的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)。針葉木(mu)薄片(pian)板(ban)(ban)(ban)的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)木(mu)紋紋路較重(zhong),芬(fen)蘭(lan)膠合木(mu)板(ban)(ban)(ban)行業將它也分(fen)為(wei)(wei)(wei)(wei)五個等級(ji)(ji),由高到(dao)低(di)依(yi)次(ci)是(shi)E、EI、EⅡ、EⅧ、EIV,E級(ji)(ji)為(wei)(wei)(wei)(wei)可直(zhi)接上清漆的高質(zhi)(zhi)量表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);EEI級(ji)(ji)為(wei)(wei)(wei)(wei)適用(yong)(yong)高質(zhi)(zhi)量涂(tu)料、染色、清漆的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);EE II級(ji)(ji)為(wei)(wei)(wei)(wei)適用(yong)(yong)普通油(you)漆、對表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)要(yao)(yao)(yao)(yao)求(qiu)不高的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);EEⅢ級(ji)(ji)為(wei)(wei)(wei)(wei)適用(yong)(yong)于(yu)對表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)要(yao)(yao)(yao)(yao)求(qiu)很低(di)的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian);EEIV級(ji)(ji)為(wei)(wei)(wei)(wei)適用(yong)(yong)于(yu)對表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)沒要(yao)(yao)(yao)(yao)求(qiu)的表(biao)(biao)(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)。

以適(shi)合用(yong)作(zuo)高檔激光(guang)刀模板的(de)(de)芬蘭(lan)(lan)膠合木板為例,該(gai)類別芬蘭(lan)(lan)板的(de)(de)基版為標準結構的(de)(de)樺木板,內用(yong)尿素甲醛膠水以十字交(jiao)叉方(fang)式粘結,以經過(guo)砂光(guang)處理的(de)(de)S級和BB級樺木薄板為表面,正反兩面均施無色或綠色透明UV固化漆,邊緣以透明丙(bing)烯(xi)酸涂料封(feng)邊。由于芬蘭(lan)(lan)板生產工藝中有去(qu)疤節(jie)處理及厚度公差控制嚴格特點,故(gu)高檔激光(guang)刀模多(duo)采用(yong),以利于刀線的(de)(de)裝嵌和回彈膠彈力的(de)(de)保證。
