Product Introduction

GM-166 微孔聚轻莫来石均化浇注料

GM-166 Microporous Lightweight Mullite Homogenized Castable

产品特点

利用聚轻莫来石微孔(纳米级)均化骨料做成的浇注料能直接与火焰接触,使用温度能达到1500℃以上,密度≤2.0 g/cm³,耐压强度≥45 MPa,导热系数≤0.800 W/(m·K)(1000℃)。并能与渣形成“隔离层”,减缓了熔渣向骨料内部渗透,因此提高了材料抵抗熔渣渗透与侵蚀的能力,能极大地延长衬体的使用寿命。是一种新型的高效节能减排材料。

Product Features

Castables made from the lightweight mullite microporous (nanometer-scale) homogenized aggregate can directly contact flames and withstand temperatures exceeding 1500°C. They have a density of ≤2.0 g/cm³, a compressive strength of ≥45 MPa, and a thermal conductivity of ≤0.800 W/(m·K) (at 1000°C). Additionally, they form an “isolation layer” with slag, slowing down molten slag penetration into the aggregate, which significantly enhances resistance to slag penetration and erosion, greatly extending the lifespan of the lining. This material is a new, high-efficiency, energy-saving, and emission-reducing solution.
