生態板廠家解析大芯板選購(gou)注意事(shi)項：

環保性：環保板材看等級

大芯板在芯板木條拼接以及板芯與表面單板膠合時都要使用膠水，這樣或多或少釋放游離甲醛。當游離甲醛含量超過一定范圍時，會影響人體健康。因此，環保細木工板與劣質細木(mu)工板(ban)(ban)(ban)的(de)(de)(de)(de)主要區(qu)別在于(yu)(yu)膠水的(de)(de)(de)(de)好壞。專家表示，由于(yu)(yu)消費者(zhe)無法現(xian)場驗(yan)證(zheng)大芯(xin)板(ban)(ban)(ban)的(de)(de)(de)(de)甲(jia)(jia)醛釋放(fang)(fang)量(liang)是(shi)否(fou)超標(biao)，所以(yi)(yi)可以(yi)(yi)聞(wen)一聞(wen)板(ban)(ban)(ban)材的(de)(de)(de)(de)氣(qi)味(wei)(wei)(wei)，對大芯(xin)板(ban)(ban)(ban)環(huan)保(bao)性進行初步判斷。若使用的(de)(de)(de)(de)膠水是(shi)環(huan)保(bao)膠，大芯(xin)板(ban)(ban)(ban)只有(you)(you)干燥的(de)(de)(de)(de)木(mu)板(ban)(ban)(ban)味(wei)(wei)(wei)，聞(wen)不到刺鼻的(de)(de)(de)(de)甲(jia)(jia)醛味(wei)(wei)(wei)道(dao)。如果大芯(xin)板(ban)(ban)(ban)散(san)發出刺鼻氣(qi)味(wei)(wei)(wei)，說明甲(jia)(jia)醛釋放(fang)(fang)量(liang)較高。此(ci)外，消費者(zhe)不能只關(guan)注商(shang)家提供(gong)的(de)(de)(de)(de)大芯(xin)板(ban)(ban)(ban)樣品，還(huan)要聞(wen)一聞(wen)堆放(fang)(fang)在賣場里的(de)(de)(de)(de)其(qi)他板(ban)(ban)(ban)材。因為樣品可能由于(yu)(yu)長時間(jian)存放(fang)(fang)，異味(wei)(wei)(wei)已經散(san)發殆盡(jin)，所以(yi)(yi)消費者(zhe)應(ying)該靠(kao)近成堆擺放(fang)(fang)特別是(shi)壓在中(zhong)間(jian)的(de)(de)(de)(de)大芯(xin)板(ban)(ban)(ban)聞(wen)一聞(wen)，是(shi)否(fou)有(you)(you)刺鼻的(de)(de)(de)(de)氣(qi)味(wei)(wei)(wei)。提醒(xing)：驗(yan)證(zheng)大芯(xin)板(ban)(ban)(ban)是(shi)否(fou)環(huan)保(bao)，還(huan)可查看其(qi)板(ban)(ban)(ban)身或檢測(ce)報(bao)告上的(de)(de)(de)(de)環(huan)保(bao)等級(ji)(ji)。大芯(xin)板(ban)(ban)(ban)根據環(huan)保(bao)標(biao)準分(fen)為E0級(ji)(ji)、E1級(ji)(ji)、E2級(ji)(ji)，E0級(ji)(ji)大芯(xin)板(ban)(ban)(ban)的(de)(de)(de)(de)甲(jia)(jia)醛釋放(fang)(fang)量(liang)≤0.5毫克/升(sheng)，E1級(ji)(ji)甲(jia)(jia)醛釋放(fang)(fang)量(liang)≤1.5毫克/升(sheng)，E2級(ji)(ji)甲(jia)(jia)醛釋放(fang)(fang)量(liang)≤5毫克/升(sheng)。其(qi)中(zhong)，E2級(ji)(ji)大芯(xin)板(ban)(ban)(ban)的(de)(de)(de)(de)環(huan)保(bao)性能較差(cha)，不能直接用于(yu)(yu)室內(nei)裝(zhuang)修。消費者(zhe)選購時要注意區(qu)分(fen)。

勻稱性：芯板木條拼(pin)接要勻稱

 大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)是否牢固(gu)耐用，關鍵(jian)在第三層芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)用材(cai)(cai)及工(gong)藝。選(xuan)購時，從側面觀察大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)構(gou)造也非常(chang)重要。大(da)維木(mu)(mu)(mu)(mu)(mu)業(ye)集團技(ji)術人員介紹，拿到(dao)一(yi)塊大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)，要仔細(xi)觀察其(qi)側面結(jie)構(gou)，特別是板(ban)(ban)(ban)(ban)(ban)芯(xin)(xin)(xin)的(de)(de)(de)(de)組合木(mu)(mu)(mu)(mu)(mu)條(tiao)。市面上大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)木(mu)(mu)(mu)(mu)(mu)條(tiao)多為(wei)杉木(mu)(mu)(mu)(mu)(mu)，正(zheng)規廠家(jia)生產的(de)(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)木(mu)(mu)(mu)(mu)(mu)條(tiao)比例均勻，單片寬度(du)(du)在5厘米左右。消(xiao)費(fei)者(zhe)選(xuan)購時，除了檢查(cha)(cha)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)木(mu)(mu)(mu)(mu)(mu)條(tiao)的(de)(de)(de)(de)寬度(du)(du)，還要檢查(cha)(cha)兩塊芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)木(mu)(mu)(mu)(mu)(mu)條(tiao)是否拼接緊(jin)密，有(you)沒有(you)明顯的(de)(de)(de)(de)縫隙(xi)。劣(lie)質的(de)(de)(de)(de)大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)木(mu)(mu)(mu)(mu)(mu)條(tiao)拼接不緊(jin)密，縫隙(xi)明顯。有(you)的(de)(de)(de)(de)廠家(jia)為(wei)了掩蓋這一(yi)缺陷，用膩(ni)子、石膏粉等(deng)材(cai)(cai)料填充在木(mu)(mu)(mu)(mu)(mu)條(tiao)的(de)(de)(de)(de)縫隙(xi)。消(xiao)費(fei)者(zhe)可(ke)(ke)查(cha)(cha)看大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)側邊，若看到(dao)有(you)補膠、補膩(ni)子現象(xiang)，說明其(qi)內部(bu)可(ke)(ke)能有(you)縫隙(xi)或空洞。提醒(xing)：如(ru)果商家(jia)允許，消(xiao)費(fei)者(zhe)可(ke)(ke)鋸下大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)一(yi)角，觀察其(qi)內部(bu)木(mu)(mu)(mu)(mu)(mu)芯(xin)(xin)(xin)的(de)(de)(de)(de)結(jie)構(gou)。中(zhong)間拼接的(de)(de)(de)(de)小(xiao)木(mu)(mu)(mu)(mu)(mu)條(tiao)不能使用有(you)樹皮、蛀孔和死結(jie)的(de)(de)(de)(de)木(mu)(mu)(mu)(mu)(mu)材(cai)(cai)。質量較好的(de)(de)(de)(de)大(da)芯(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)，木(mu)(mu)(mu)(mu)(mu)條(tiao)之間的(de)(de)(de)(de)銜接很密實。

平整性：外表(biao)要平整光滑

大芯(xin)板(ban)的(de)(de)質量是否合格，直觀的(de)(de)檢查方法是看其外(wai)觀。大芯(xin)板(ban)的(de)(de)外(wai)層是單(dan)板(ban)，優質的(de)(de)單(dan)板(ban)厚度在0.35毫(hao)米以(yi)上。一般正規廠家生產的(de)(de)單(dan)板(ban)經過雙面砂光處理，外(wai)觀平整，板(ban)面光滑(hua)(hua)，表(biao)面也沒(mei)有明顯的(de)(de)色差(cha)。而劣(lie)質的(de)(de)大芯(xin)板(ban)由于生產工藝不過關，表(biao)面往(wang)往(wang)做工粗糙，有毛刺、凹(ao)凸不平等情(qing)況。提(ti)醒(xing)：檢查平整性(xing)時，消費(fei)者要用(yong)手去觸(chu)摸，光滑(hua)(hua)感越強，說明板(ban)材表(biao)面處理越到(dao)位。

穩定(ding)性(xing)：中(zhong)板越(yue)(yue)厚(hou)板材越(yue)(yue)穩定(ding)

大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)由內(nei)到外(wai)可(ke)分為(wei)(wei)芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)和面板(ban)(ban)(ban)(ban)(ban)(ban)(ban)三(san)層(ceng)。大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)二層(ceng)面板(ban)(ban)(ban)(ban)(ban)(ban)(ban)通常稱為(wei)(wei)中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，主要(yao)起到穩定芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)木(mu)條的(de)作用，所以中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)越厚，大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)穩定性越好。上(shang)方板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)的(de)中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)較薄(bo)，容易造成大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)抗彎曲(qu)度(du)(du)不(bu)足，下方板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)的(de)中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)厚度(du)(du)合適(shi)。由于(yu)(yu)大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)屬(shu)于(yu)(yu)多層(ceng)結構，每層(ceng)材(cai)(cai)料的(de)質(zhi)量(liang)高低都(dou)會(hui)影響(xiang)總體(ti)(ti)質(zhi)量(liang)。一(yi)些小廠家(jia)生(sheng)產(chan)的(de)大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)為(wei)(wei)了節省(sheng)成本，使(shi)用的(de)中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)很(hen)薄(bo)，造成大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)抗彎曲(qu)度(du)(du)不(bu)足。如果用力彎折，此(ci)類大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)容易從兩片芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)木(mu)條的(de)縫隙處裂開。此(ci)外(wai)，很(hen)多商家(jia)銷售(shou)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)時(shi)(shi)都(dou)是疊(die)加(jia)堆放，消費者挑(tiao)選大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)時(shi)(shi)，可(ke)以先看這疊(die)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)中(zhong)每塊板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)的(de)側面，觀(guan)察其(qi)中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)厚度(du)(du)是否一(yi)致。若厚度(du)(du)基本一(yi)致，說明(ming)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)加(jia)工(gong)工(gong)藝水準較高，質(zhi)量(liang)也有(you)保障(zhang)。提醒：鑒別大芯(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)質(zhi)量(liang)，還可(ke)以敲擊(ji)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)表(biao)面，聽(ting)一(yi)聽(ting)聲(sheng)音(yin)的(de)差異，如果聲(sheng)音(yin)有(you)變化(hua)，說明(ming)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)內(nei)部存(cun)在(zai)空洞(dong)。這樣的(de)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)整體(ti)(ti)強度(du)(du)較弱，長期受力不(bu)均會(hui)使(shi)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)(cai)結構發生(sheng)扭曲(qu)、變形，影響(xiang)外(wai)觀(guan)及使(shi)用。
