落葉松(song)(song)特點(dian)：落葉松(song)(song)木(mu)(mu)方是電桿(gan)、枕木(mu)(mu)、橋(qiao)梁(liang)、礦(kuang)柱(zhu)、車輛、建筑等優(you)良用(yong)材。同時，由于落葉松(song)(song)樹(shu)勢高大挺拔，冠形美觀，根(gen)系十分發達(da)，抗(kang)煙能力強。所(suo)以，又是一個優(you)良的園(yuan)林(lin)綠化樹(shu)種。落葉松(song)(song)的木(mu)(mu)材重而堅實(shi)，抗(kang)壓(ya)及抗(kang)彎曲的強度大，而且耐(nai)腐朽，木(mu)(mu)材工藝價值高。

落葉松用途推薦：小高層、別(bie)墅、廠(chang)房(fang)等(deng)建筑

奧(ao)松特點(dian)：奧(ao)松木方外觀與(yu)輻射松接近，但相(xiang)比輻射松，結(jie)巴(ba)更(geng)小。中密度，結(jie)構(gou)均(jun)勻，收縮(suo)效率(lv)平均(jun)，穩定性強的軟材。完(wan)好(hao)的原木不存在腐(fu)朽、心腐(fu)和(he)蟲咬(yao)等(deng)問題。木材握釘力好(hao)，滲透(tou)性強，極易防腐(fu)、干燥、固化(hua)和(he)上(shang)色等(deng)處理。

奧松(song)用(yong)途推薦(jian)：工地常用(yong)的建筑木(mu)方

建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方如果在(zai)潮濕環境(jing)會容易發(fa)生變質、腐爛、發(fa)臭等現象，建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方多少錢，所以建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方的(de)(de)(de)保存一(yi)般都在(zai)干燥(zao)通(tong)風的(de)(de)(de)地方。新(xin)鮮建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方含有(you)大量的(de)(de)(de)水分，花旗(qi)松建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方，在(zai)特(te)定環境(jing)下水分會不(bu)斷(duan)蒸(zheng)發(fa)。水分的(de)(de)(de)自然(ran)蒸(zheng)發(fa)會導致(zhi)建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方出現干縮、開裂、彎(wan)曲變形、霉變等缺陷(xian)，武漢(han)建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方，嚴重(zhong)影響建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方制(zhi)(zhi)品(pin)(pin)的(de)(de)(de)品(pin)(pin)質，因(yin)此建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方在(zai)制(zhi)(zhi)成(cheng)各類木(mu)(mu)(mu)(mu)制(zhi)(zhi)品(pin)(pin)之前必(bi)須進行強(qiang)制(zhi)(zhi)（受(shou)控制(zhi)(zhi)）干燥(zao)處(chu)理。正(zheng)確(que)的(de)(de)(de)干燥(zao)處(chu)理可以克服上述建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方缺陷(xian)，提建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方的(de)(de)(de)力學強(qiang)度，改善建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方的(de)(de)(de)加工(gong)。它是(shi)合理利用(yong)建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方，使建(jian)(jian)(jian)(jian)(jian)(jian)筑(zhu)(zhu)(zhu)木(mu)(mu)(mu)(mu)方增值(zhi)的(de)(de)(de)重(zhong)要技術措施，也是(shi)木(mu)(mu)(mu)(mu)制(zhi)(zhi)品(pin)(pin)生產不(bu)可缺少的(de)(de)(de)要工(gong)序。

判斷建筑木(mu)方(fang)內部含(han)水量的(de)方(fang)法

一、掂重

判斷建筑方(fang)木含(han)水量簡單(dan)的(de)(de)方(fang)法(fa)是(shi)通過手觸(chu)法(fa)，建筑木方(fang)一(yi)方(fang)多少錢，即：將手置于(yu)方(fang)木上感(gan)受(shou)是(shi)否有(you)強烈的(de)(de)潮濕感(gan)，但是(shi)許多方(fang)木外部經過烘干之后，其內部的(de)(de)含(han)水量仍有(you)，此時使用(yong)(yong)觸(chu)摸法(fa)判斷較困難，所以可以用(yong)(yong)掂重法(fa)，即：將方(fang)木懸(xuan)起，從(cong)空(kong)中(zhong)感(gan)受(shou)它的(de)(de)重量， 般含(han)水量較的(de)(de)方(fang)木為輕便(bian)，但是(shi)含(han)水率的(de)(de)建筑方(fang)木會(hui)有(you)明顯的(de)(de)阻力。

二、敲釘

敲釘(ding)(ding)法(fa)(fa)是判(pan)斷建(jian)筑方木含水量的(de)(de)重要(yao)方法(fa)(fa)，也是準(zhun)確的(de)(de)方法(fa)(fa)之 。具體為(wei)：使用小錘將長釘(ding)(ding)釘(ding)(ding)于建(jian)筑方木內(nei)，如果(guo)在釘(ding)(ding)入時無(wu)任何阻力即可將方木釘(ding)(ding)穿，這說明該方木的(de)(de)含水量低，反之則代表其內(nei)部較(jiao)潮(chao)濕。
