If you are looking for customized and cheap calcium feldspar insulating firebrick made in China from a calcium feldspar insulating firebrick factory, Zibo Qunhui Refractory Co.,Ltd is always at your service.

Description

High temperature insulating foam materials belong to original high-tech products of China. The materials with tiny closed-pores and crystal lattice foam net structure are produced by using fine particles as main starting materials through some advanced technical processes, such as self-developed concentrated suspending solution preparation process, steady foaming agent surface activity preparation process, gel casting and rapid gelling shaping process, etc. The materials have some marked advantages of high refractoriness, low density, high strength, and good thermal shock resistance, can replace the conventional medium- and high-temperature insulating materials, can reflect high level and quality of China’s new type light-weight insulting materials.

Application

1. Primary hot face linings
2. Back-up insulation for furnaces and kilns
3. Flue insulation
4. Sulphur recovery equipment
5. Hot blast stoves

Advantage

Low impurities (such as alkali) content and good carburization resistance

High service temperature (1100℃—1260℃)

Higher strength than the conventional light weight refractory insulating bricks

Low bulk density (0.45—0.55 g/cm3)

Low thermal conductivity and linear expansion coefficient

Good thermal stability. The products can be heated or cooled rapidly, increasing the efficiency of industrial furnaces greatly.

Special shaped or big block products, easy to process and install

Easy maintenance
