style="text-indent:25px">目前我國鋼絞線的年產(chǎn)量約為160~200萬t。其中環(huán)氧涂層鋼絞線(鋼筋)按20%計，其產(chǎn)量為32~40萬t。每噸環(huán)氧涂層鋼絞線(鋼筋)需用環(huán)氧粉末涂料約50~70kg，意味著目前我國該領(lǐng)域年需求1.6~2萬t環(huán)氧粉末涂料。我國鋼絞線(鋼筋)產(chǎn)量的年增長率超過20%。環(huán)氧涂層鋼絞線(鋼筋)的應(yīng)用比例也在逐年速增。因此對粉末涂料行業(yè)來說環(huán)氧涂層鋼絞線(鋼筋)是很有吸引力的市場。按照鐵道部《中長期鐵路網(wǎng)規(guī)劃調(diào)整方案》精神，到2020年包括“四縱四橫”八條高速客運(yùn)專線、三大經(jīng)濟(jì)區(qū)域城際客運(yùn)專線等在內(nèi)的新建高鐵里程將達(dá)到1.6萬km，另外在這些鐵路線上需要架設(shè)的橋梁數(shù)量是相當(dāng)可觀的，公路網(wǎng)的發(fā)展也同樣需要架設(shè)大量橋梁。鐵路及橋梁建設(shè)對環(huán)氧涂層鋼筋的需求量將成倍增長，市場潛力巨大。曲線段體外預(yù)應(yīng)力鋼束的摩擦系數(shù)與采用的體外預(yù)應(yīng)力鋼束類型有關(guān)。買預(yù)應(yīng)力鋼絞線性能</p><p
