面對巨大的開發壓力膨潤土該怎么發展
作者:管理員    發布于:2013-10-11 17:18:18
    膨潤土具備多種特性是很多行業喜歡的礦產,可以應用于很多行業,特別是在環保行業有著巨大的作用。膨潤土在我國的開發較晚,在世界范圍內,美國是膨潤土的生產大國也是消費大國。而我國膨潤土在蘊藏量上雖然非常豐富,在開發量方面也是非常的巨大。但是也是有其弊端的,例如說在利用程度方面,應用領域較低時一方面,但是利用效率和附加值方面太低又成為了我國膨潤土發展的瓶頸。
    面對并不樂觀的開發環境,膨潤土在我國的發展面臨了很多困難,我國的膨潤土該如何發展呢?
    我國由于在膨潤土礦開發的歷史時間較短,目前主要以縣辦企業,鄉鎮企業為主,生產規模多屬中、小型。而且單鑄造用膨潤土就占總產量的73.5%,但因普遍要求濕壓強度在58.8kPa以上,而中國多數鑄造土產品只達19.6~29.4kPa,因而生產高精鑄件用土尚需進口。
    終上所述,我國的膨潤土想要得到更好的發展,必須要注重可持續發展,進行合理的開發利用,除此之外,提升精煉水平也很重要。
