Chimney lined, flue lined with lightweight insulation castables and performance characteristics

Nov 07,2017
Light insulation refractory castable, that is, the true porosity of not less than 45% of the castable refractory, also known as lightweight refractory castables. Lightweight castable is aluminate cement, high-alumina fines, ceramsite, plus a number of additives from the configuration, the product has a light weight, high compressive strength, acid and acid gas corrosion. Insulation, insulation, low water absorption characteristics, easy construction, high temperature is alkali corrosion parts of the construction of the ideal product.

Light insulation refractory castable with light weight, high strength, good insulation properties, small bulk density, low thermal conductivity, good thermal insulation, uniform temperature, energy saving and high fire resistance, overall performance, spalling resistance Good, long service life and other characteristics, can be any shape repair or processing of the overall lining.

Application:

Suitable for pouring forming amorphous refractory material. Compared with other unshaped refractory materials, the binder and the moisture content are higher and the fluidity is better. Therefore, the unshaped refractory material has a wide range of applications, and the material and the binder can be selected according to the conditions of use. Can be directly cast into the lining to use, but also use pouring or shock method made of prefabricated block. Good workability, strong adhesive force, good initial setting time and operable construction time, rapid strength increase, good impermeability, no need of acidizing treatment, easy to ensure the dense and full of mortar gray joints, and significantly improve the lining of the chimney The wall's airtightness, integrity and lined corrosion protection make it ideal for high chimneys, high temperature flue and duct linings.
