style="text-indent:25px">從泡沫混凝土的制備原理分析，利用發(fā)泡劑引入大量氣孔賦予其普通混凝土所沒有的輕質(zhì)、隔音、保溫、高流動(dòng)性等功能是泡沫混凝土制備的基礎(chǔ)；但從結(jié)構(gòu)和力學(xué)的角度看，同時(shí)也引起結(jié)構(gòu)致密性極大可能降低，從而降低了泡沫混凝土的強(qiáng)度。發(fā)泡劑對(duì)泡沫混凝土強(qiáng)度的影響主要體現(xiàn)在泡沫的尺寸、均勻性(尺寸均勻性和分布均勻性)、泡沫的穩(wěn)定性、發(fā)泡能力等。要求發(fā)泡劑的發(fā)泡能力強(qiáng)、密度低、單位攜水量小，泡沫牢固、細(xì)小、均勻分布，對(duì)混凝土的副作用小。</p><p style="text-indent:25px">目前，我國(guó)熱力管道及熱工設(shè)備對(duì)保溫材料的需求量為250萬(wàn)m3/年，*一個(gè)電廠就需保溫材料2-5萬(wàn)m3，北方冬季供暖熱力管道及工廠熱力管道度保溫材料的需求更為驚人。目前的主導(dǎo)產(chǎn)品礦棉類無(wú)機(jī)纖維使人皮膚瘙癢、吸水性強(qiáng)、價(jià)格高，也急需換代，泡沫混凝土在這一方面也會(huì)大有作為。1957年前后，我國(guó)曾利用蘇聯(lián)技術(shù)生產(chǎn)應(yīng)用了6萬(wàn)m3泡沫混凝土熱力管道保溫外殼，用于大連電廠及峰峰電廠的熱工管道保溫。后因中蘇關(guān)系惡化而停止生產(chǎn)。這表明泡沫混凝土取代無(wú)機(jī)纖維棉是可行的。目前，泡沫混凝土尚無(wú)在這一領(lǐng)域應(yīng)用，急需開發(fā)。昆明發(fā)泡混凝土廠家哪家好？</p><div
