Description
Technical field
The invention belongs to Lightweight ceramic porcelain plate preparation technical field, in particular to a kind of production of lithium tailing light ceramic plate
Method.
Background technique
When exploiting lithium feldspar, lepidolite, spodumene concentrate, a large amount of lithium tailing can be generated.Currently, due to lithium tailing without
Effective use means are discarded stacking or simply landfill disposal mostly, that is, cause the waste of resource, and cause two secondary environments
Pollution, needs to improve resource utilization with a kind of technical treatment.
Light ceramic plate is a kind of excellent building exterior wall material, has low density, high intensity, high fire resisting
Degree, good thermal shock resistance and low thermal conductivity.Preparation method is to mix the raw material including foaming agent, fill saggar
After carry out high temperature sintering, sintering temperature is generally at 1200 degree or less.Since dress saggar is fired, resistance to material heat absorption energy consumption is huge, therefore
Higher cost.
Summary of the invention
To achieve the above object, the technical scheme is that：
A kind of production method of lithium tailing light ceramic plate, is to be prepared from the following raw materials：Lithium 30~85wt% of tailing is high
Ridge 10~60wt% of soil, 3~10wt% of talcum powder, 0.2~3wt% of foaming agent；
Preparation method includes the following steps：
1) it takes raw material to carry out dry method powder, after mixing in proportion, obtains mixture；
2) be stirred, be granulated after mixture being added water, drying, be sieved after obtain particulate material；
3) particulate material is fitted into saggar, is fired after paving, obtain light ceramic plate after cooling.
Further, the foaming agent is silicon carbide.
Further, the firing final temperature in step 3) is 1100~1200 degree.
Further, elemental lithium content is not less than 1wt% in the lithium tailing, and iron content is not less than 0.5%.
Further, the cooling in step 3) include the first quench zone and the second slow cooling section, cold section of third tail, according to product
Thickness is different, and cooling time is different.General thickness is thicker, and cooling time is longer.It is pumped through using latter section of Low Temperature Thermal wind-fall cold
But the last period high-temperature hot-air is conducive to control the temperature difference, avoids splitting brick.
Beneficial point of the invention is：The present invention is to produce light ceramic plate using lithium tailing, due in lithium tailing
Most of ingredient is clay and feldspar, and contains a certain amount of elemental lithium and ferro element.When being used to make light ceramic plate,
It wherein can be used as fluxing agent containing elemental lithium and ferro element, significantly reduce firing temperature, shorten firing period.It can save
Production cost is greatly reduced in energy consumption.
In addition, ordinary circumstance can be raw in lower temperature range when using lithium tailing to prepare light ceramic plate
At eutectic, therefore firing temperature can be reduced.But the lithium tailing light ceramics plate porosity by Traditional Firing Craft of Red preparation is low
In conventional light ceramic wafer, heat-proof quality is poor, and intensity also slightly reduces.Inventor, which analyzes reason, to exist for foaming agent
800-900 degree temperature range forms hole, and in cooling stage, aluminium oxide is initially formed continuous solid phase, skeleton is constituted, after cooling
The eutectic of phase remnants is still liquid phase, when cooling velocity is slower, may play and fill out to part hole after liquid phase composition diffusion
Effect is filled, and the liquid phase may cause to corrode to skeleton structure has been formed, to influence ceramics strength.
Inventor makes improvements the technique of lithium tailing light ceramic plate, utilizes aluminium element in kaolin in formula
Effect, enhances the skeleton structure of green body.By improving, light ceramic plate obtained by the present invention can reach traditional handicraft
Index.
