Abstract
The present invention provides a flyash aluminium silicate heat-insulating material which can be substituted for pyrogemstone and has small mass, good resistance to high temp., good thermal stability and low heat conductivity. Its composition includes (wt%) 40-90% of flyash, 5-50% of high-alumina vanadine and 5-40% of aluminium oxide. Said invented heat-insulating material and its products have the extensive application range.
Description
The present invention relates to a kind of lagging material, particularly a kind of flyash Gui Suan Aluminum lagging material.
Background technology: China is the bigger country of lagging material demand, also is the big country that produces lagging material.At present, Gui Suan Aluminum lagging material and goods thereof that China produces all adopt flint clay as raw material basically, and along with gradually reducing and shortage gradually of this Mineral resources of flint clay, its price also rises steadily, and this is on the one hand; On the other hand, Power Plant in China is all wanted the waste material-flyash of ten million ton of the number of discharge every year, and these flyash had both taken a large amount of soils, farmland, again severe contamination environment, become well-known public hazards.
Summary of the invention: technical problem to be solved by this invention is: provide a kind of and can substitute flint clay and quality is little, high temperature resistant, Heat stability is good, flyash Gui Suan Aluminum lagging material that thermal conductivity is low.Its technical scheme is: a kind of flyash Gui Suan Aluminum lagging material is characterized in that its feed composition and weight percent thereof:
Flyash 40-90 high alumina bauxite 5-50 Yangization Aluminum 5-40
Above-mentioned raw materials dissolves the cotton method of system by resistance furnace and makes behind batching.
Lagging material of the present invention detects it through power construction institute of office of State Grid and the results are shown in following table:
Test subject standard value average detected value is estimated
128-192 165 is qualified for density (Kg/m)
Thermal conductivity W/Cm.K≤0.153 0.0337 is qualified
Maximum operation (service) temperature C 1,000 10000 is qualified
Slag ball content Φ 0.25mm≤15.0≤11.5 are qualified
By detected result as can be known, lagging material of the present invention has that quality is little, high temperature resistant, Heat stability is good, thermal conductivity is low, thermal capacitance is little and advantage such as anti-mechanical vibration, belongs to the light-weight refractory filamentary material.Lagging material of the present invention and heat insulating products thereof, alternative flint clay Gui Suan Aluminum lagging material is widely used in fields such as metallurgy, building materials, material, electric power, oil, chemical industry, electronics, boats and ships, guided missile, satellite, aerospace and nuclear power.
Lagging material of the present invention, owing to adopt pulverized fuel ash as raw materials, utilization of waste material is turned waste into wealth, and has both solved flyash and has taken soil, a large amount of farmland, problem of environment pollution caused, has saved the Mineral resources of a large amount of preciousnesses again.Compare with flint clay Gui Suan Aluminum lagging material, its cost also reduces greatly, has the high commercial value and the very strong market competitiveness.
Embodiment:
Embodiment 1.Flyash 40, high alumina bauxite 50, oxygen Aluminum 5 behind batching, dissolve the cotton method of system by resistance furnace and make.
Embodiment 2.Flyash 65, high alumina bauxite 30, oxygen Aluminum 20 behind batching, dissolve the cotton method of system by resistance furnace and make.
Embodiment 3.Flyash 90, high alumina bauxite 5, oxygen Aluminum 40 behind batching, dissolve the cotton method of system by resistance furnace and make.
