Description
Technical field
The present invention relates to ceramic molding, specifically a kind of non-conventional type ceramic moulding process.
Background technology
At present, the shaping of ceramics typically uses gypsum mold grouting process；Run into abnormally-structured product general
Assembled again after being molded using packer grouting.Not only complex process, Production Time are long for the way assembled again after this slurry molding, and
It is also unworkable particularly with some special shells or special shape packer groutings and the requirement to technology is high.Up to the present
Also neither one can make the technique of non-conventional type ceramic disposal molding.
Due at present with the cardinal principle of plaster formulation be in ceramic slurry containing moisture it is flowable, pour into after gypsum mold
Make ceramics fixed-type because gypsum absorbs moisture content, molded ceramic body is taken out in the then demoulding.But gypsum mold except
Be not durable outer, also one fatal shortcoming is exactly that, without elasticity, all products for having barb shape can not be stripped, i.e., special-shaped
Product is unable to disposal molding；And plastic mould is although flexible but it can not absorb water, it is impossible to make ceramic slurry dehydration forming.Institute
To want to realize the disposal molding of non-conventional type ceramic, the most important point must be such that ceramics shaping breaks away from dehydration forming
Old model.
The content of the invention
It is an object of the invention to provide a kind of non-conventional type ceramic moulding process of disposal molding.
To achieve the above object, the present invention provides following technical scheme：
Non-conventional type ceramic moulding process, comprises the following steps：
（1）Raw material processing：After using commercial run, the clinker after pre-sintering is crushed, the screen cloth of 100~150 mesh of mistake, dry
Ripe powder, it is standby；
（2）The preparation of compound：Raw material according to mass percent weighs ripe powder 75-85% and paraffin 15~25%, puts into pot
Heating, is mixed into uniform integral mixture, cooling is standby up to melted paraffin wax and with ripe powder；
（3）Shaping：Reheat the mixture of ripe powder and paraffin, during thing good fluidity to be mixed, pour the mixture into it is special-shaped into
The silica gel mould of type is interior and fills up whole mould, and it is 10~60 seconds to make the time that mixture is rested in mould, then by mould
Interior mixture is all poured out, and is cooled down and is stripped, the product being molded（The thickness of the product of the shaping stops depending on mixture
The time stayed in mould）；
Mould can entrust specialized factory to be produced, and its Making programme is substantially：Created with sculpture soil（Note receiving
Shrinkage is 1.10~1.13% or so）, or in shape is reduced, upper silica gel is molded with existing finished product but the product that is made, due to silicon
Glue high resilience is easy to the demoulding（This is can to carry out special-shaped one-time formed basis）, silica gel external application gypsum shaped.
（4）Dewaxing：The product of shaping is put into sintering furnace, aluminum oxide is added and the product of shaping is sintered into dewaxing, treat stone
Wax is burnt out, and is heated to stopping at 600~850 DEG C, closed to be cooled to normal temperature, and taking-up obtains biscuit；
（5）Finishing colouring glazing：Biscuit is repaired, unwanted part is removed, is then painted according to traditional method
Glazing；
（6）Burn till：Firing temperature is seen depending on the composition of clinker, typically between 950~1200 DEG C.
It is used as further scheme of the invention：The step（1）In, the clinker after pre-sintering is replaced with into ceramic product
Waste material.
It is used as further scheme of the invention：The step（2）In, compound is according to the raw material of mass percent by ripe powder
84% and paraffin 16% constitute.
It is used as further scheme of the invention：The paraffin is industrial paraffin.
It is used as further scheme of the invention：The step（3）In, heating-up temperature is 190~210 DEG C, and the heat time is
20~30 minutes.
It is used as further scheme of the invention：The step（3）In, heating-up temperature is 195~205 DEG C.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention makes ceramics that cooling and shaping can be achieved by the effect of paraffin using the cold melt and coagulating property of paraffin.
The present invention, under cryogenic can be real by by after ceramic raw material and paraffin mixed melting, pouring into silica gel mould and being molded
Existing non-conventional type ceramic product disposal molding, the technique has overturned the old model of traditional ceramic dehydration forming completely.By this hair
Bright technique, can produce shell, special shell, the non-conventional type ceramic product of printing opacity.
Ceramic raw material of the present invention can also use Production of Ceramics and use process in addition to using new clay
The waste material of middle generation, this is that other moulding process are not accomplished, this is one very big for the utilization of ceramic product waste material
Break through.
