異型膠合板也是裝修中經常用到(dao)的材料之(zhi)一，膠合板的種類有很多，膠合板的密度及厚度都是衡量(liang)其好壞的一個重要(yao)因素。

膠合板密度

異型膠(jiao)(jiao)(jiao)(jiao)合(he)(he)板(ban)密(mi)度越大，質量越好。一(yi)般大于同材種的(de)(de)(de)木材。膠(jiao)(jiao)(jiao)(jiao)合(he)(he)時的(de)(de)(de)單(dan)位(wei)壓力越大，則膠(jiao)(jiao)(jiao)(jiao)合(he)(he)板(ban)的(de)(de)(de)密(mi)度也越大。由于木材在高溫下(xia)易產生(sheng)塑(su)性變(bian)形，熱(re)壓膠(jiao)(jiao)(jiao)(jiao)合(he)(he)比冷壓膠(jiao)(jiao)(jiao)(jiao)合(he)(he)的(de)(de)(de)壓縮(suo)率要(yao)大。由于膠(jiao)(jiao)(jiao)(jiao)合(he)(he)板(ban)由縱橫交錯的(de)(de)(de)單(dan)板(ban)配制而(er)成，其導熱(re)系數低于同材種的(de)(de)(de)木材。

異型膠合板的(de)(de)最外層單板稱(cheng)表板，正面(mian)的(de)(de)表板稱(cheng)為(wei)面(mian)板，反面(mian)的(de)(de)表板稱(cheng)為(wei)背板，內層的(de)(de)單板稱(cheng)為(wei)芯板或中板。

膠合板厚度

膠合(he)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)是由一些薄的(de)木片組成(cheng)的(de)，有三合(he)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、五合(he)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)等(deng)(deng)等(deng)(deng)，偶爾也(ye)會(hui)有奇數。根(gen)據不同層板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)組合(he)，異型膠合(he)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)厚度也(ye)有所(suo)不同，一般有3厘(li)(li)(li)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、5厘(li)(li)(li)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、9厘(li)(li)(li)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、12厘(li)(li)(li)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、15厘(li)(li)(li)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、18厘(li)(li)(li)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)等(deng)(deng)幾種規格，當然根(gen)據特殊情況也(ye)會(hui)有其(qi)他的(de)厚度。

膠合板層數方面的一(yi)些規律：

膠合板厚度每增加3mm，其層數(shu)將增加2層;

同(tong)樣厚度的膠合板，層數越(yue)多強(qiang)度越(yue)大(da)，比如(ru)15層18mm的膠合板強(qiang)度比13層18mm膠合板大(da);

同樣(yang)厚度的(de)膠(jiao)合板，層數(shu)越(yue)多價格越(yue)高，比(bi)如7層6.5mm膠(jiao)合板的(de)價格比(bi)5層6.5mm膠(jiao)合板的(de)價格高。
