Than it is close when, the weight of the wear resistance lining being made reduces and toughness strengthens, so that wear resistance lining is easy with cyclone body
In anchoring.
Specifically, in one embodiment of the invention, the aggregate includes：Any one in white fused alumina and ceramics or two
Plant, preferably the mixture of white fused alumina and ceramics.
Because the density of ceramics is 2380kg/m3Left and right, compared with white fused alumina density (>3900kg/m3) small, therefore from pottery
Porcelain can further reduce the weight of wear resistance lining as the aggregate of wear resistance lining, so that wear resistance lining and cyclone separator master
Body is easier to anchoring.
In addition, waste ceramic is as a kind of solid waste in Ceramic production, because it have passed through high-temperature firing, firmly
Degree is high, it is impossible to reuses, can not also digest naturally as ceramic raw material, can only carry out landfill disposal as industrial refuse.
And the main raw material(s) for producing ceramics is the non-renewable resources such as natural earth, ore deposit, directly landfill waste ceramic is very big to resource
Waste, and environment can be damaged.Therefore, waste ceramic is realized into discarded object recycling as the aggregate of wear resistance lining,
The cost of wear resistance lining has not only been saved, environmental protection is also helped.
Specifically, in one embodiment of the invention, from waste ceramic as wear resistance lining aggregate when, selection it is ceramic
Particle diameter is：100~300 μm, the particle diameter for the white fused alumina that aggregate includes also is 100~300 μm.This causes ceramics and white fused alumina tool
There are good skeleton and supporting role.
In addition, the particle diameter of flyash is 0.5~100 μm so that flyash has good filling effect.In practical application
When, flyash as thermal power plant discarded object, be it is a kind of by differing in size, the high dispersive that particle in irregular shape is constituted
Aggregate, its particle diameter is general at 0.5~300 μm., can be by while save production cost in order that discarded object is well utilized
Flyash in the μ m of particle diameter 0.5~300 as the raw material of wear resistance lining, wherein, in the μ m of particle diameter 100~300
The actual skeleton for serving as aggregate of flyash and the flyash being made in effect, the μ m of particle diameter 0.5~100 have the filling of powder
Effect.In order to ensure filling effect that powder is good, so that it is guaranteed that the intensity of wear resistance lining, by the powder in 0.5~300 μ m
Coal ash as wear resistance lining raw material when, need to ensure that the fly ash content in the μ m of particle diameter 0.5~100 accounts for flyash total content
More than 50%.
In one embodiment of the invention, binding agent selects aluminate cement.Due to containing three more oxidations in flyash
Two aluminium, it can be reacted with the calcium oxide in aluminate cement and a calcium aluminate in middle thermophase, and a calcium aluminate is generated respectively
And Calcium dialuminate, 20% and 13% volumetric expansion can be produced respectively in course of reaction, made so as to avoid in wear resistance lining
During, because of the contraction that hydrated product is dehydrated and produces, and then improve the intensity of wear resistance lining.In addition, bonding agent is also optional
With portland cement or the mixture of aluminate cement and portland cement.
In order to improve in the heat-conducting effect of wear resistance lining, one embodiment of the invention, the additive includes：One-dimensional carbon is fine
Any one or more in dimension, one dimension fibre shape carborundum and one dimension fibre shape silicon nitride.
Because the toughness of fine and close ceramic-like lining is poor, cause heat resistanceheat resistant poor-performing of the lining during driving and parking.
Therefore in the present embodiment, one-dimensional carbon fiber, one dimension fibre shape carborundum and one dimension fibre shape are increased in wear resistance lining raw material
The one dimension fibre shape material such as silicon nitride does additive, can further enhance the toughness of wear resistance lining, so as to improve wear resistance lining
Thermal shock resistance.Simultaneously as these materials have good thermal conductivity, therefore thermal stress suffered by wear resistance lining can be made evenly,
So as to improve the heat-conducting effect of wear resistance lining.
