Abstract
The invention discloses a light thermal insulation and heat preservation castable. The castable comprises main raw materials such as vitrified micro bubbles, closed cell perlite, floating beads, golf mullite hollow spheres, silica fume, white mud, ceramic dusting powder, high-aluminum cement and solid water glass and is also added with a dispersing agent, aluminum-silicon sol and aluminum silicate fibers. The castable is simply and quickly constructed, capital construction cost is reduced, and resources are saved.
Description
Technical field
The present invention relates to refractory castable.
Background technology
Low-carbon economy is the economic model that is the basis with less energy-consumption, low pollution, low emission.Its aim is that development is the economy of essential characteristic with less energy-consumption, low pollution, low emission.Come down to how to improve the problem of energy utilization rate.Improving one of effective means of energy utilization rate is exactly to adopt lightweight refractory.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of Ultra-light Castable with excellent heat insulation and preservation effect, reduces the thermal losses of high temperature kiln and various industrial high temperature equipment.
