蛭石膨胀工艺研究进展
|
摘要
膨胀蛭石是一种优良的保温耐火、吸音隔热、耐冻蚀的环保节能材料,应用领域十分广泛。我国蛭石矿产资源丰富,但开发利用与国外相比存在着产品品种少、膨胀工艺简单、细粒蛭石的利用率低等问题。传统的蛭石膨胀工艺是燃料加热法和电加热法,随着蛭石膨胀工艺发展,目前主要还有微波膨胀和化学膨胀等方法。通过对蛭石膨胀工艺的深入研究,可进一步促进蛭石环保节能材料的开发与应用。
Exfoliated vermiculite is an excellent thermal and acoustic insulated environment-friendly and energy-saving material, with the characters of fire-resistant,corrosion-resistant and freeze-resistant,which can be applied very widely.There's abundant of vermiculite mineral resources in our country, but the development and utilization has many problems such as less product variety,simple rough expansion process, low utilization oi fine particle vermiculite compared with foreign countries.The traditional vermiculite expansion process was thermal exfoliated by fuel or electricity.With the development of vermiculite technology, the main process at present is microwave exfoliated and chemical exfoliated. It could further accelerate the exploitation and application of the environment-friendly and energy-saving materials through the in-depth study of vermiculite processing.
