用(yong)(yong)松(song)(song)(song)木做家具(ju)，由(you)于松(song)(song)(song)油(you)（松(song)(song)(song)脂）殘存在(zai)松(song)(song)(song)木里或滲出表面，不(bu)僅造成油(you)漆困難，而且影(ying)(ying)響美觀(guan)和使(shi)用(yong)(yong)效(xiao)果。不(bu)論采用(yong)(yong)哪種方法(fa)處(chu)理(li)，都需(xu)要再用(yong)(yong)乙醇（酒精）擦洗一遍或涂(tu)一層蟲膠(jiao)清漆，以防松(song)(song)(song)木內沒有除凈的松(song)(song)(song)油(you)滲出，影(ying)(ying)響漆膜。
用(yong)(yong)松(song)(song)木(mu)做家具，由于松(song)(song)油(you)(you)（松(song)(song)脂）殘存在松(song)(song)木(mu)里或滲出表(biao)面(mian)，不僅造成油(you)(you)漆困難，而(er)且(qie)影響美觀和使用(yong)(yong)效(xiao)果。若想除掉松(song)(song)木(mu)里的(de)松(song)(song)油(you)(you)，可(ke)(ke)以(yi)選用(yong)(yong)下列方法(fa)：1.堿(jian)洗(xi)(xi)法(fa)：用(yong)(yong)8％～10％的(de)碳(tan)酸鈉（食(shi)用(yong)(yong)堿(jian)面(mian)）水(shui)溶液，或4％～6％的(de)燒堿(jian)溶液，清洗(xi)(xi)松(song)(song)木(mu)有(you)松(song)(song)油(you)(you)的(de)部位，使松(song)(song)油(you)(you)皂化（油(you)(you)和堿(jian)發生作用(yong)(yong)而(er)變(bian)成肥(fei)皂和甘油(you)(you)），然后用(yong)(yong)海綿(mian)或刷子(zi)蘸熱水(shui)（40℃～50℃）擦洗(xi)(xi)、沖(chong)凈(jing)。2.漂洗(xi)(xi)法(fa)：將(jiang)20克漂白粉(fen)，加溫水(shui)1市(shi)斤，使其溶解(jie)，用(yong)(yong)這(zhe)種溶液反復涂刷松(song)(song)木(mu)有(you)松(song)(song)油(you)(you)的(de)部位，直到稍有(you)變(bian)白，再用(yong)(yong)水(shui)沖(chong)凈(jing)。3.溶解(jie)法(fa)：用(yong)(yong)25％的(de)丙酮水(shui)溶液溶解(jie)，還可(ke)(ke)用(yong)(yong)20％的(de)丙酮水(shui)溶液和少量(liang)堿(jian)的(de)混合液刷洗(xi)(xi)。4.鏟除法(fa)：對(dui)松(song)(song)油(you)(you)滲出比較多的(de)局部，可(ke)(ke)以(yi)用(yong)(yong)鏟刀(dao)把(ba)局部鏟除，然后再用(yong)(yong)膩子(zi)嵌平(ping)。
不(bu)論采用(yong)哪種(zhong)方法(fa)處理，都需要再用(yong)乙醇(chun)（酒精）擦(ca)洗(xi)一(yi)(yi)遍(bian)或涂一(yi)(yi)層(ceng)蟲膠(jiao)清(qing)漆，以防松(song)木內沒有(you)除凈(jing)的松(song)油滲出，影響(xiang)漆膜。 |
