等離子體處理

我們使用這種方法(fa)就(jiu)是在真空的(de)條(tiao)件下不斷提(ti)供(gong)少(shao)量(liang)的(de)氣(qi)體，由放電產生等離子體，在木(mu)材表(biao)(biao)面結(jie)合(he)或聚合(he)氣(qi)體分子。這樣(yang)出(chu)來的(de)結(jie)果及時可以改善木(mu)材表(biao)(biao)面的(de)著色性(xing)和染色性(xing)等。

塑料樹脂(zhi)復合改性處理

進行這個方法處理之(zhi)后的結(jie)果就(jiu)是可使(shi)木材的硬度和強度提高(gao)幾(ji)倍，耐(nai)磨性也顯著提高(gao)，并(bing)且(qie)使(shi)木材表面具有光澤，制做成(cheng)包裝后不易污損。

通(tong)常按產(chan)品(pin)密(mi)度(du)(du)分非(fei)壓(ya)(ya)縮型和(he)(he)壓(ya)(ya)縮型兩大(da)類。非(fei)壓(ya)(ya)縮型產(chan)品(pin)為(wei)(wei)軟質(zhi)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)，密(mi)度(du)(du)小于(yu)0.4克(ke)(ke)/厘(li)米3；壓(ya)(ya)縮型產(chan)品(pin)有中(zhong)(zhong)密(mi)度(du)(du)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)（或稱半硬質(zhi)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)，密(mi)度(du)(du)0.4～0.8克(ke)(ke)/厘(li)米3）和(he)(he)硬質(zhi)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)(密(mi)度(du)(du)大(da)于(yu)0.8克(ke)(ke)/厘(li)米3)。根據板(ban)(ban)(ban)(ban)(ban)坯成型工(gong)藝可分為(wei)(wei)濕法纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)、干法纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)和(he)(he)定向(xiang)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)。按后期(qi)處理方(fang)法不(bu)同(tong)又可分為(wei)(wei)普通(tong)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)、油處理纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)等。 軟質(zhi)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban) 質(zhi)輕，空(kong)隙(xi)率大(da)，有良好的隔熱性(xing)和(he)(he)吸(xi)聲性(xing)，多用(yong)(yong)作公共(gong)建筑(zhu)物(wu)內部(bu)的覆蓋材料。經特殊(shu)處理可得到(dao)孔隙(xi)更多的輕質(zhi)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)，具(ju)有吸(xi)附性(xing)能，可用(yong)(yong)于(yu)凈化空(kong)氣。 中(zhong)(zhong)密(mi)度(du)(du)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban) 結構(gou)均勻，密(mi)度(du)(du)和(he)(he)強度(du)(du)適中(zhong)(zhong)，有較(jiao)好的再(zai)加工(gong)性(xing)。產(chan)品(pin)厚度(du)(du)范圍(wei)較(jiao)寬，具(ju)有多種用(yong)(yong)途，如家具(ju)用(yong)(yong)材、電(dian)視機的殼體材料等。 硬質(zhi)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban) 產(chan)品(pin)厚度(du)(du)范圍(wei)較(jiao)小，營口木箱(xiang)，在3～8毫(hao)米之間。強度(du)(du)較(jiao)高，3～4毫(hao)米厚度(du)(du)的硬質(zhi)纖(xian)(xian)(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)可代(dai)替9～12毫(hao)米鋸材薄板(ban)(ban)(ban)(ban)(ban)材使(shi)用(yong)(yong)。多用(yong)(yong)于(yu)建筑(zhu)、船舶、車輛(liang)等。

國(guo)刨花(hua)板(ban)行(xing)業發(fa)展較快，但普(pu)遍存(cun)在規(gui)模小、設備和技術落后的(de)問(wen)題(ti)，加(jia)上許多企業不注意產(chan)(chan)(chan)品(pin)(pin)質(zhi)量(liang)，把(ba)樹(shu)皮和中(zhong)纖板(ban)生(sheng)(sheng)產(chan)(chan)(chan)出的(de)粉(fen)塵等都(dou)用(yong)作刨花(hua)板(ban)的(de)原(yuan)料，膠合板(ban)木(mu)(mu)箱，所以，中(zhong)國(guo)生(sheng)(sheng)產(chan)(chan)(chan)的(de)刨花(hua)板(ban)普(pu)遍質(zhi)量(liang)較差，訂做木(mu)(mu)箱，而且也(ye)普(pu)遍存(cun)在甲醛嚴(yan)重超標的(de)問(wen)題(ti)。在這種形(xing)勢下，刨花(hua)板(ban)業必須迅速提(ti)(ti)高(gao)(gao)產(chan)(chan)(chan)品(pin)(pin)的(de)質(zhi)量(liang)和降低成本，積極參(can)與(yu)市場競爭，產(chan)(chan)(chan)品(pin)(pin)的(de)市場空間還是巨大(da)的(de)。除(chu)了保證(zheng)原(yuan)材料供(gong)應和提(ti)(ti)高(gao)(gao)產(chan)(chan)(chan)品(pin)(pin)質(zhi)量(liang)外，企業要(yao)加(jia)大(da)科技，大(da)力(li)(li)回收廢(fei)舊木(mu)(mu)材，實現循環經濟。努力(li)(li)開發(fa)刨花(hua)板(ban)新用(yong)途，特別要(yao)加(jia)大(da)對(dui)定向刨花(hua)板(ban)的(de)研究和對(dui)刨花(hua)板(ban)用(yong)途的(de)宣傳力(li)(li)度，為了提(ti)(ti)高(gao)(gao)刨花(hua)板(ban)的(de)質(zhi)量(liang)和降低成本及提(ti)(ti)高(gao)(gao)研發(fa)能力(li)(li)，必須提(ti)(ti)高(gao)(gao)項目的(de)建設規(gui)模，把(ba)小型的(de)刨花(hua)板(ban)廠進行(xing)重組，體(ti)現規(gui)模效益。
