聚酯生產仍以纖用聚酯

在產品品種(zhong)方面(mian)，目前我國(guo)(guo)(guo)聚(ju)(ju)(ju)酯(zhi)生產仍(reng)以纖用(yong)聚(ju)(ju)(ju)酯(zhi)為主，占總年產能力(li)的88%；國(guo)(guo)(guo)內非纖用(yong)聚(ju)(ju)(ju)酯(zhi)切片年產能力(li)約100萬(wan)噸(dun)，其中聚(ju)(ju)(ju)酯(zhi)瓶片發(fa)展(zhan)特(te)別(bie)迅速(su)，僅2002年就新增(zeng)50多萬(wan)噸(dun)年產能力(li)。但由于國(guo)(guo)(guo)內市場容量有限，因此(ci)聚(ju)(ju)(ju)酯(zhi)瓶片裝置(zhi)開(kai)工率(lv)不足50%。  

在(zai)產(chan)品構成(cheng)方面，我國(guo)聚酯(zhi)包裝(zhuang)用樹脂(zhi)生(sheng)(sheng)產(chan)能(neng)力(li)居世界第(di)(di)2位，僅次于美(mei)(mei)國(guo)；聚酯(zhi)薄膜的(de)(de)生(sheng)(sheng)產(chan)能(neng)力(li)從1990年(nian)的(de)(de)世界第(di)(di)12位，一舉躍升至目前的(de)(de)第(di)(di)5位，前4位國(guo)家分別為美(mei)(mei)國(guo)、日(ri)本、韓國(guo)和印度。預計到2005年(nian)，我國(guo)聚酯(zhi)薄膜的(de)(de)生(sheng)(sheng)產(chan)能(neng)力(li)將超(chao)過印度，達到15萬噸，上(shang)升至世界第(di)(di)4位。2003年(nian)5月(yue)，儀(yi)征化纖(xian)公司在(zai)國(guo)內成(cheng)功(gong)開發(fa)出(chu)聚酯(zhi)薄膜專用料(liao)-膜級切片，并在(zai)儀(yi)化滌綸二廠大裝(zhuang)置上(shang)實現工業(ye)化生(sheng)(sheng)產(chan)。此產(chan)品的(de)(de)開發(fa)成(cheng)功(gong)，為正在(zai)建設的(de)(de)儀(yi)化450噸/天聚酯(zhi)專用料(liao)項目提(ti)供了技術支撐。  

聚酯網廠家根(gen)據有關部門預測(ce)，到2005年，中國(guo)用(yong)于碳酸軟飲料、礦泉水、醫藥、日化產(chan)品、熱灌裝(zhuang)飲料、酒(jiu)類等行業(ye)中的(de)(de)PET聚酯瓶的(de)(de)需求量將達到60萬(wan)～65萬(wan)噸，各種聚酯瓶坯的(de)(de)消費量也將超過200億只。但是(shi)目前，中國(guo)大規模生(sheng)產(chan)PET聚酯瓶的(de)(de)企業(ye)只有上海紫江(jiang)企業(ye)和珠海中富公司兩家，年生(sheng)產(chan)能力分別為4.85億只和5.5億只。  

儀征化纖公司自主開發成功(gong)10萬(wan)噸/年(nian)瓶級聚酯(zhi)固相(xiang)縮聚國產化專有技術(shu)。2003年(nian)11月底，年(nian)產20萬(wan)噸瓶級聚酯(zhi)切片技術(shu)改造項目建設正(zheng)式啟(qi)動。  

聚酯纖(xian)維(滌綸)  

80年(nian)(nian)代后，隨著合成(cheng)(cheng)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)工業的(de)(de)迅速(su)發展，我(wo)(wo)國(guo)聚酯(zhi)的(de)(de)消(xiao)費量(liang)也快速(su)增(zeng)(zeng)(zeng)(zeng)長(chang)。1990年(nian)(nian)合成(cheng)(cheng)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)用聚酯(zhi)表觀(guan)消(xiao)費量(liang)為105.4萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，1995年(nian)(nian)增(zeng)(zeng)(zeng)(zeng)加到(dao)(dao)(dao)268.9萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)。2000年(nian)(nian)表觀(guan)消(xiao)費量(liang)增(zeng)(zeng)(zeng)(zeng)長(chang)到(dao)(dao)(dao)616.8萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，2001年(nian)(nian)達(da)(da)到(dao)(dao)(dao)710.7萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，2002年(nian)(nian)達(da)(da)到(dao)(dao)(dao)859.7萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)。我(wo)(wo)國(guo)聚酯(zhi)的(de)(de)消(xiao)費絕大(da)部分用于生(sheng)產(chan)(chan)(chan)滌(di)(di)(di)綸(lun)(lun)(lun)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)。滌(di)(di)(di)綸(lun)(lun)(lun)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)是我(wo)(wo)國(guo)合成(cheng)(cheng)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)中增(zeng)(zeng)(zeng)(zeng)長(chang)快的(de)(de)品種(zhong)，1965年(nian)(nian)滌(di)(di)(di)綸(lun)(lun)(lun)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)產(chan)(chan)(chan)量(liang)只有100噸(dun)(dun)(dun)(dun)，僅占(zhan)我(wo)(wo)國(guo)合成(cheng)(cheng)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)總(zong)產(chan)(chan)(chan)量(liang)約(yue)1.92%，位(wei)(wei)于錦綸(lun)(lun)(lun)、維(wei)(wei)綸(lun)(lun)(lun)和腈綸(lun)(lun)(lun)之后而居第四位(wei)(wei)。1976年(nian)(nian)滌(di)(di)(di)綸(lun)(lun)(lun)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)產(chan)(chan)(chan)量(liang)上(shang)升(sheng)到(dao)(dao)(dao)2.69萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，超過(guo)上(shang)述三種(zhong)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)而躍居，占(zhan)合成(cheng)(cheng)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)總(zong)產(chan)(chan)(chan)量(liang)的(de)(de)34.3%。1990年(nian)(nian)產(chan)(chan)(chan)量(liang)突破100萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，達(da)(da)到(dao)(dao)(dao)104.2萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)。2001年(nian)(nian)產(chan)(chan)(chan)量(liang)猛(meng)增(zeng)(zeng)(zeng)(zeng)到(dao)(dao)(dao)632.6萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，2002年(nian)(nian)更達(da)(da)到(dao)(dao)(dao)772.1萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，創歷史記錄(lu)。1996～2002年(nian)(nian)間，我(wo)(wo)國(guo)滌(di)(di)(di)綸(lun)(lun)(lun)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)平均年(nian)(nian)遞增(zeng)(zeng)(zeng)(zeng)82萬(wan)(wan)(wan)(wan)噸(dun)(dun)(dun)(dun)，占(zhan)世界(jie)年(nian)(nian)均增(zeng)(zeng)(zeng)(zeng)量(liang)的(de)(de)一(yi)半(ban)以上(shang)，成(cheng)(cheng)為推動(dong)世界(jie)聚酯(zhi)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)增(zeng)(zeng)(zeng)(zeng)長(chang)的(de)(de)主(zhu)要國(guo)家。近期內，我(wo)(wo)國(guo)滌(di)(di)(di)綸(lun)(lun)(lun)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)產(chan)(chan)(chan)量(liang)仍(reng)將以10%的(de)(de)年(nian)(nian)率增(zeng)(zeng)(zeng)(zeng)長(chang)，生(sheng)產(chan)(chan)(chan)滌(di)(di)(di)綸(lun)(lun)(lun)纖(xian)(xian)(xian)(xian)(xian)(xian)維(wei)(wei)消(xiao)耗聚酯(zhi)約(yue)占(zhan)聚酯(zhi)總(zong)消(xiao)費量(liang)的(de)(de)90%。
