国产碳纤维管的发展
　　我国(guo)(guo)(guo)(guo)对(dui)(dui)碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)的(de)(de)(de)研(yan)究(jiu)(jiu)开始于(yu)20世(shi)纪60年(nian)(nian)(nian)(nian)(nian)代(dai)，80年(nian)(nian)(nian)(nian)(nian)代(dai)开始研(yan)究(jiu)(jiu)高强(qiang)型碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)。多年(nian)(nian)(nian)(nian)(nian)来(lai)进展(zhan)(zhan)缓慢，但(dan)也取得了一(yi)(yi)定成绩。进入(ru)21世(shi)纪以(yi)来(lai)发展(zhan)(zhan)较快，安(an)徽华皖碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)公司率先引(yin)进了500吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian)原(yuan)丝(si)、200吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian)PAN基碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)(只(zhi)有(you)(you)东丽碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)T300水平)，使我国(guo)(guo)(guo)(guo)碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)工业进入(ru)了产(chan)(chan)业化(hua)。随(sui)后(hou)，一(yi)(yi)些厂家(jia)相继加入(ru)碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)生(sheng)产(chan)(chan)行(xing)列。据不(bu)(bu)(bu)完全统计(ji)，目前(qian)，我国(guo)(guo)(guo)(guo)已(yi)有(you)(you)12家(jia)生(sheng)产(chan)(chan)规模大(da)小(xiao)不(bu)(bu)(bu)一(yi)(yi)(5～800吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian))的(de)(de)(de)PAN基碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)生(sheng)产(chan)(chan)厂家(jia)，合(he)计(ji)生(sheng)产(chan)(chan)能(neng)力(li)(li)为(wei)(wei)(wei)1310吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian)，产(chan)(chan)品(pin)规格为(wei)(wei)(wei)1K、3K、6K、12K。但(dan)由于(yu)一(yi)(yi)些企业没(mei)有(you)(you)原(yuan)丝(si)可烧，实际国(guo)(guo)(guo)(guo)内碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)的(de)(de)(de)总产(chan)(chan)量不(bu)(bu)(bu)足40吨(dun)(dun)/年(nian)(nian)(nian)(nian)(nian)，而(er)且产(chan)(chan)品(pin)质量不(bu)(bu)(bu)太稳定，大(da)多数达不(bu)(bu)(bu)到(dao)T300水平。可喜(xi)的(de)(de)(de)是从2000年(nian)(nian)(nian)(nian)(nian)开始我国(guo)(guo)(guo)(guo)碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)向技(ji)(ji)术(shu)多元化(hua)发展(zhan)(zhan)，放(fang)弃了原(yuan)来(lai)的(de)(de)(de)硝酸法原(yuan)丝(si)制造技(ji)(ji)术(shu)，采用以(yi)二甲(jia)基亚砜(feng)为(wei)(wei)(wei)溶剂的(de)(de)(de)一(yi)(yi)步法湿法纺丝(si)技(ji)(ji)术(shu)获得成功(gong)。目前(qian)利用自主技(ji)(ji)术(shu)研(yan)制的(de)(de)(de)少数国(guo)(guo)(guo)(guo)产(chan)(chan)T300、T700碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)产(chan)(chan)品(pin)已(yi)经达到(dao)国(guo)(guo)(guo)(guo)际同类产(chan)(chan)品(pin)水平。碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)生(sheng)产(chan)(chan)线　　随(sui)着近(jin)年(nian)(nian)(nian)(nian)(nian)来(lai)我国(guo)(guo)(guo)(guo)对(dui)(dui)碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)的(de)(de)(de)需求量日益增长(zhang)，碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)已(yi)被列为(wei)(wei)(wei)国(guo)(guo)(guo)(guo)家(jia)化(hua)纤(xian)(xian)行(xing)业重点扶持的(de)(de)(de)新产(chan)(chan)品(pin)，成为(wei)(wei)(wei)国(guo)(guo)(guo)(guo)内新材料行(xing)业研(yan)发的(de)(de)(de)热点。据不(bu)(bu)(bu)完全统计(ji)，目前(qian)拟建和(he)在建的(de)(de)(de)碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)生(sheng)产(chan)(chan)企业有(you)(you)11家(jia)，合(he)计(ji)生(sheng)产(chan)(chan)能(neng)力(li)(li)为(wei)(wei)(wei)原(yuan)丝(si)7100吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian)、碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)1560吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian)，其中在建企业为(wei)(wei)(wei)4家(jia)，合(he)计(ji)生(sheng)产(chan)(chan)能(neng)力(li)(li)为(wei)(wei)(wei)原(yuan)丝(si)1100吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian)、碳纤(xian)(xian)维(wei)(wei)(wei)(wei)(wei)470吨(dun)(dun)／年(nian)(nian)(nian)(nian)(nian)。
