一、電木塑料
電(dian)木(mu)(mu)料又稱熱固(gu)性(xing)(xing)(xing)塑料,或膠木(mu)(mu)料,它是指樹(shu)脂(zhi)在加(jia)(jia)工(gong)(gong)過程中發(fa)生化學變化,分子結構從加(jia)(jia)工(gong)(gong)前的線性(xing)(xing)(xing)結構轉(zhuan)變為網(wang)狀(zhuang)體(ti)型(xing)結構,一經成型(xing)后(hou)再加(jia)(jia)熱也不(bu)(bu)能軟化流(liu)動的一類聚合物(wu)。電(dian)木(mu)(mu)料在性(xing)(xing)(xing)能上與熱塑性(xing)(xing)(xing)塑料有許多不(bu)(bu)同之處,除(chu)不(bu)(bu)能循(xun)環(huan)使(shi)用外,它具有強(qiang)度(du)高(gao),耐熱溫度(du)高(gao),加(jia)(jia)工(gong)(gong)尺寸精度(du)高(gao)及耐電(dian)弧(hu)性(xing)(xing)(xing)好(hao)等(deng)優(you)點。
目前常用電木料有酚醛樹脂,氨基樹脂,環氧樹脂和不飽和聚酯等四種。其他的普通電木樹脂還有脲甲醛、三聚氰胺甲醛、有機
