Description
Technical field
The present invention relates to a kind of insulating layer material, more particularly to a kind of pipeline thermal insulation material.
Background technology
Red mud be with bauxite as raw material production alumina process in produce fines strong basicity solid waste, often give birth to
One ton of aluminium oxide is produced, 0.8~1.5 ton of red mud is about produced.China is alumina producing big country, produces aluminium oxide 2378 within 2009
Ten thousand tons, the 30% of Gross World Product is accounted for, the red mud of generation is nearly 30,000,000 tons.At present China's red mud comprehensive utilization ratio is only 4%,
Accumulation volume of cargo in storage reaches 200,000,000 tons.With increasing year by year for China's aluminium oxide yield and being gradually lowered for bauxite grade, red mud
Yield will also be continuously increased in year, and by 2015, the accumulative volume of cargo in storage of red mud was up to 3.5 hundred million tons.Red mud is stored up in a large number, both takes
Soil, waste of resource easily causes environmental pollution and potential safety hazard again.
Now factory's either chemical pipeline conveying liquid charging stock or during heat exchange material, needs to raw material or heat exchange material
It is incubated, but most chemical pipeline is not only longer, and having many bends or curves, the mistake of raw material or heat exchange material in conveying
It is easier to lose the temperature of its own in journey, causes process materials conveying more difficult.At present, in most chemical plant using asbestos or
Person sponge is wrapped up pipeline, or seals one layer of cement in pipeline outer-layer, to reaching the effect of insulation, but such as comprehensive institute
State, play more chemical pipeline and go, in corner, easily turned round using asbestos and the more difficult operation of sponge wrapping, and energy
Place is lost in.Pipeline can be incubated using cement, although effect is good not as sponge and asbestos, easy to operate, low cost.Cause
This, needs at present a kind of low cost, easy to operate, high insulating effect pipe insulation material badly.
