粉煤灰空心微珠微小而空心,质轻而高强,保温且耐火,是制造轻质隔热材料的理想原料。目前常用的轻质耐火制品,如轻质粘土制品、硅藻土保温砖、轻质高铝砖,甚至是高级型耐火制品,虽然在低温下有较好的保温性能,但在高温下其保温性能显著下降,而用微珠制得的轻质隔热材料,不仅在常温下有较前者为优的隔热性能,即使在高温下仍具有极优
Fly ash hollow microspheres are tiny and hollow, lightweight, high-strength, heat-insulating and fire-resistant. They are ideal raw materials for the manufacture of lightweight insulation materials. Currently used lightweight refractory products, such as lightweight clay products, diatomaceous earth insulation bricks, light high alumina bricks, and even high-grade refractory products, although at a low temperature have good thermal insulation properties, but its insulation at high temperatures The performance is significantly reduced, and the lightweight heat insulation material made of microbeads not only has better heat insulation performance than the former at room temperature, but is excellent even at high temperatures.
