UNBURNED EXPANDED VERMICULITE-BASED CERAMICS HAVING EXCELLENT STRENGTH AND THERMAL INSULATION

摘要

The present invention relates to a fluorine-quality seokgye castle expansion ceramic having excellent strength and heat insulating performance, the present invention In one aspect of the wt.%, swelling vermiculite: 75 ~ 97%, the organic binder: 1-12%, the inorganic binder: comprising 2 to 13%, wherein the organic binder is a phenolic resin, wherein the inorganic binder is boric acid and boric acid provides a fluorine-sex expansion seokgye quality ceramics and its manufacturing method having excellent strength and thermal insulation which comprises at least one species of the soda. According to an aspect of the invention, strength and heat insulating performance is excellent in heat insulating material can be used for various heating devices in various fields, and especially well suited for use as a heat insulating material such as a ladle, crosstalk car, a converter used in the steel industry and, energy saving and work efficiency gains can provide excellent quality inflatable castle fluorine seokgye ceramics. ;
