山東玄武巖講述從重視程度上看：目前我國(guó)對(duì)玄武巖纖維的發(fā)展具有較強(qiáng)的國(guó)家影響力。從行業(yè)發(fā)展基礎(chǔ)上看：近幾十年來我國(guó)玻纖、碳纖維及其復(fù)合材料等得到了飛速發(fā)展，這為玄武巖研發(fā)生產(chǎn)和推廣應(yīng)用奠定了堅(jiān)實(shí)的基礎(chǔ)，我們面臨著嚴(yán)重的纖維短缺問題，玄武巖將帶動(dòng)全球復(fù)合材料產(chǎn)業(yè)的強(qiáng)勁增長(zhǎng)，從資源儲(chǔ)備優(yōu)勢(shì)上看：因玄武巖纖維及其復(fù)合材料有望發(fā)揮替代玻纖、碳纖維等材料后發(fā)優(yōu)勢(shì)而稱雄世界，特別是它取材源自于天然礦石，加工過程無(wú)污染，是典型的資源節(jié)約型新材料，它有利于資源綜合利用和環(huán)境保護(hù)，有利于實(shí)現(xiàn)可持續(xù)發(fā)展戰(zhàn)略目標(biāo)。而國(guó)內(nèi)礦石儲(chǔ)量豐富，來源充足，新生代的火山巖絕大部分為玄武巖，尤其是堿性玄武巖在全球比較占有優(yōu)勢(shì)。根據(jù)研究人員已掌握的玄武巖礦石化學(xué)組分分析數(shù)據(jù)證明，在我國(guó)很多省份都有適合玄武巖生產(chǎn)的礦址，省其中某些省的礦石已在工業(yè)試驗(yàn)裝置上生產(chǎn)出玄武巖纖維產(chǎn)品。從生產(chǎn)成本效益上看：中國(guó)具備了低成本制造玄武巖得天獨(dú)厚的條件，因天然玄武巖礦石原料價(jià)格較低廉，無(wú)需人工配料，工藝流程比一般玻璃纖維生產(chǎn)過程要簡(jiǎn)捷多了。直接從玄武巖一次制成玄武巖工藝和裝備可降低生產(chǎn)成本，提高生產(chǎn)效率，遞增企業(yè)效益。</p><div

隨著現(xiàn)代我們對(duì)玄武巖石子的使用，在進(jìn)行生產(chǎn)使用時(shí)會(huì)發(fā)現(xiàn)有的玄武巖石子會(huì)產(chǎn)生變形，這是為什么呢下面我們一起來看下：1、巖性：影響玄武巖石子形變特征的基本因素，石英砂巖、片麻巖等巖石硬度大，彈性變形的屈服強(qiáng)度大往往表現(xiàn)出脆性變形；而石灰?guī)r等各種巖鹽類巖石則往往表現(xiàn)出塑性變形。2、含水量：孔隙裂隙水可以削弱礦物晶體的化學(xué)鍵強(qiáng)，減少裂隙內(nèi)的摩擦力所以含水量大的巖石趨向于塑性變形。3、圍壓：圍壓增高，玄武巖石子難于破裂傾向于塑性變形。4、溫度：溫度的升高彈性極限降低，玄武巖石子很快進(jìn)入塑性階段，表現(xiàn)為塑性變形。5、時(shí)間的原因：玄武巖石子的脆、韌性因施力長(zhǎng)短不同而不同，如果應(yīng)力作用時(shí)間長(zhǎng)，玄武巖應(yīng)變率低所以即便是堅(jiān)硬的巖石，也可以轉(zhuǎn)化為塑性變形。地質(zhì)作用往往長(zhǎng)期和緩慢，即便是脆性的玄武巖石子，也可以發(fā)生塑性變形。以上五種因素就是影響玄武巖石子變形的主要原因了，大家如果想了解更多關(guān)于玄武巖石子的相關(guān)產(chǎn)品知識(shí)可以繼續(xù)關(guān)注我們。</p></p><br
