High Quality Light Weight Insulating Refractory Castables Good Insulating Property Grey Insulating Castable
Light Weight Clay insulation castable is characterized by light weight, high compressive strength, acid and acidproof gas corrosion, thermal insulation, thermal insulation and low fineness rate. As lightweight thermal insulation castable is made of certain refractory materials, such as alumina, firelcay insulation castable is made of powder and granular refractory with some binder, and has high fluidity, refractory clay insulation castable is mainly formed by pouring in construction.
Firelcay insulation castable is an unshaped material delivered in the state of dry powder, and mixed before use, can harden at the ambient temperature to achieve adobe strength after construction without heating. Refractory clay insulation castable composed of refractory lightweight aggregate, powder, binder and admixture and other components. Clay insulation castablehas characteristics of small volume, high compressive strength, good acid and acid gas corrosion resistance, good insulation performance, low water absorption.
.High compactness, high abrasive resistance,
.Excellent thermal shock stability,
.Excellent anti strip performance,
.Excellent fouling resistance,
.Excellent mobility and suitable construction time.
Fire clay insulation castable is made from different types of lightweight aggregates, powders, binders, clay and swelling agents. Clay insulation castableis a very good new thermal insulation and energy-saving material. Fireclay insulation castable has high strength, small bulk density, low thermal conductivity, good heat insulation performance and convenient construction, and is applied to various heat insulation parts of kiln.
Clay insulation castable has good heat preservation performance and strong integrity, so it saves energy, over 20%, than ordinary refractories. With high refractoriness and spalling resistance performance, it has long service life. Fireclay insulation castable can be used to repair the kiln or furnace, thus improve the service life of such thermal equipment as well, thus saves money.
