電(dian)(dian)(dian)木是塑料(liao)中一個投入(ru)工業生(sheng)產(chan)的品種(zhong)，電(dian)(dian)(dian)木的化學稱(cheng)叫喊酚(fen)醛(quan)塑料(liao)，它具有較高的機(ji)械強度(du)(du)、良好的絕(jue)緣性(xing)(xing)(xing)，耐(nai)(nai)熱、耐(nai)(nai)腐蝕，因(yin)此常(chang)用(yong)于制(zhi)造電(dian)(dian)(dian)器(qi)材(cai)料(liao)，如(ru)開關、燈頭、耳機(ji)、電(dian)(dian)(dian)話機(ji)殼(ke)、儀表殼(ke)等(deng)，“電(dian)(dian)(dian)木”由(you)此而得名(ming)。酚(fen)醛(quan)塑料(liao)是一種(zhong)硬而脆的熱固性(xing)(xing)(xing)材(cai)料(liao)。電(dian)(dian)(dian)木的特性(xing)(xing)(xing)是不吸(xi)水、不導電(dian)(dian)(dian)、耐(nai)(nai)高溫、強度(du)(du)高，多用(yong)在電(dian)(dian)(dian)器(qi)上，因(yin)像木頭相同絕(jue)緣性(xing)(xing)(xing)高可(ke)塑性(xing)(xing)(xing)好，所以被叫做“電(dian)(dian)(dian)木”。電(dian)(dian)(dian)木是用(yong)粉狀的酚(fen)醛(quan)樹脂，加進鋸木屑、石(shi)棉或陶(tao)土等(deng)混

　　一(yi)、電(dian)(dian)(dian)(dian)木簡介。　　電(dian)(dian)(dian)(dian)木，俗稱膠木，學(xue)名酚醛模(mo)塑(su)料，是(shi)熱固型塑(su)膠的(de)一(yi)種，也是(shi)至早投入工業出產的(de)塑(su)料。電(dian)(dian)(dian)(dian)木注塑(su)用到的(de)電(dian)(dian)(dian)(dian)木粉(fen)是(shi)由(you)酚醛樹(shu)脂，鋸木粉(fen)，以及硬化劑(ji)，固化劑(ji)，增(zeng)塑(su)劑(ji)，著色劑(ji)，潤滑劑(ji)，固化增(zeng)強劑(ji)等添加劑(ji)組(zu)成的(de)。更可(ke)以對電(dian)(dian)(dian)(dian)木粉(fen)進行各種需求的(de)改性，電(dian)(dian)(dian)(dian)木粉(fen)中有(you)(you)40%左(zuo)右的(de)添加劑(ji)。酚醛樹(shu)脂是(shi)苯酚與甲醛的(de)縮聚物，具有(you)(you)機械強度高，性能穩定，耐(nai)酸(suan)堿，耐(nai)高溫(wen)低(di)溫(wen)，硬度高耐(nai).磨損，不親水(shui)，電(dian)(dian)(dian)(dian)器絕緣(yuan)性優(you)異是(shi)一(yi)種理
