Description
Technical field
The present invention relates to domestic ceramics manufacturing technology field, and in particular to a kind of wear-resistant, high-low temperature resistant ceramic pan and
Its manufacturing process.
Background technology
Compared with metal pan, temperature rising is slower when ceramic pan is heated, and can so allow food uniform and fully heated, can use
In cooking, Baoshang, deep fried foodstuff, and ceramic pan also has weight big, the crisp frangible weakness of matter, and ceramic pan top layer generally has
One layer improve ceramic pan gloss, wearability and corrosion resistance glaze layer, during routine use, if glaze layer is worn, quite
In the protective layer for destroying ceramic pan, its wearability and corrosion resistance are reduced, so that its service life is reduced, with living standard
Increasingly raising, quality, class requirement also more and more higher of the people to domestic ceramics pot.
The content of the invention
Based on above prior art, it is an object of the invention to provide a kind of wear-resistant, high-low temperature resistant ceramic pan, its is heavy
Lighter, convenient use is measured, and with high-wearing feature, be available for daily persistently using more than 50 years.
To achieve these goals, the technical solution adopted by the present invention is:A kind of wear-resistant, high-low temperature resistant ceramic pan,
Including base substrate and the glaze layer for imposing on billet surface, it is characterised in that the base substrate is made by the raw material of following parts by weight:Kaolin
30~45 parts, 23~30 parts of bone meal, 15~25 parts of silica flour, 10~20 parts of feldspar powder, 8~14 parts of bentonite, waste and old broken ceramics
13~20 parts of powder, 10~15 parts of waterglass, 10~15 parts of land plaster, 5~10 parts of silica flour;The glaze layer by following parts by weight original
Material is made:10~20 parts of kaolin, 5~12 parts of silica flour, 5~8 parts of bone meal, 5~15 parts of pigment, 1~5 part of silica flour.
Preferably, the base substrate is made by the raw material of following parts by weight:40 parts of kaolin, 25 parts of bone meal, silica flour 20
Part, 14 parts of feldspar powder, 11 parts of bentonite, waste and old broken 17 parts of ceramic powder, 13 parts of waterglass, 12 parts of land plaster, 8 parts of silica flour;It is described
Glaze layer is manufactured using the following raw material:14 parts of kaolin, 8 parts of silica flour, 6 parts of bone meal, 10 parts of pigment, 4 parts of silica flour.
Preferably, the granularity of the waste and old broken ceramic powder is 100~300 microns, the granularity of the silica flour is 20~200
Nanometer, the granularity of waste and old broken ceramic powder is somewhat larger, relative while ensureing that ceramic pan hardness is made with toughness can reduce it
Weight, the granularity of silica flour is smaller, can be filled up the hole constituted in raw material in ceramics, so as to ensure the hardness of ceramic pan
With wearability.
Present invention also offers a kind of technique for manufacturing wear-resistant, high-low temperature resistant ceramic pan, following steps are included:
Step 1:More than 10 minutes shapes are stirred after kaolin, bone meal, silica flour, feldspar powder, waste and old broken ceramic powder are mixed
Into well mixed ceramic powder;
Step 2:Add to stir after the water for accounting for 8~15 times of its weight into bentonite and expand and formed suspension completely to it
Liquid, continues to stir, is obtained after sequentially adding the ceramic powder obtained in waterglass, land plaster and above-mentioned steps 1 in whipping process
Pug is mixed, mixed soil is anticipated into type and obtains crude green body body, afterwards according to silica flour:Water=1:3~5 weight is than by bad body raw material
In silica flour mixed with water after spraying plating carry out sharp base in crude green body body inner and outer surfaces, after drying in the shade naturally and obtain base substrate;
Step 3:Glaze water is made with accounting in glaze layer raw material after the water of 1.5~3 times of its gross weight is mixed, then to the above-mentioned step of step
Rapid 2 obtained base substrates carry out glazings and simultaneously dried, and the base substrate after finally glazing is dried is placed in nitrogen environment, it is warming up to 1000~
1200 DEG C sinter 30~180 minutes, and then sintering obtains wear-resistant, resistance to for 0.5~2 hour under conditions of 1300 DEG C~1500 DEG C
The ceramic pan of high/low temperature.
The present invention use the principle of raw material and burning process for:Using kaolin, bone meal, silica flour, feldspar powder, waste and old broken
Ceramic powder, land plaster, silica flour as manufacture ceramic body primary raw material, wherein, waste and old broken ceramic powder is will be broken waste and old
Ceramics are ground obtained powder, and ceramic hardness is big, is ground to after powder, its powder granule is larger so that what step 1 was obtained
Hole inside ceramic powder is larger, so that obtaining ceramics in firing is internally formed larger hole, the density of overall reduction ceramic pan.
Hole in the ceramic powder that step 1 is obtained is big, can make the viscosity decline of pug made from step 2, so as to easily make final firing
Obtain ceramic pan excessively matter crisp frangible, thus stirring forms after suspension and adds pottery after first being added water in step 2 into bentonite
Porcelain powder formation pug, bentonite can make the viscosity increase of pug, and the viscous of pug can be then made after being combined with the waterglass of rear addition
Property is bigger, so as to increase its plasticity and toughness, aftershaping after silica flour is mixed with water after spraying plating in crude green body body, appearance
Face, glazing dry after in step 3 in a nitrogen environment in sintering process, the part silicon in ceramic pot reacts with nitrogen to be generated
Silicon nitride, silica has the performances such as excellent high rigidity, wearability, corrosion resistance, inoxidizability, cold-and-heat resistent, thus this
When ceramic pan it is overall there is certain high intensity, obtained after then being sintered under conditions of 1300 DEG C~1500 DEG C
Light weight, wear-resistant, high-low temperature resistant, corrosion resistant ceramic pan.
Preferably, according to silica flour in the step 2:Water=1:4 weight is than by the silica flour and water in bad body raw material
Spraying plating, i.e., will not be because of water on crude green body body after the silica flour under crude green body body inner and outer surfaces, this ratio is mixed with water for spraying plating after mixing
Excessively dry its difficulty, and can also make the silicon of spraying plating uneven because water is very few.
Make preferred, the base substrate after glazing is dried in the step 3 is placed in nitrogen environment, be warming up to 1135 DEG C of sintering 95
Minute, ceramic pan base substrate now has been provided with certain hardness and abrasion resistance, is then sintered 1 hour under conditions of 1455 DEG C
Obtain wear-resistant, high-low temperature resistant ceramic pan, light weight, wear-resistant, high-low temperature resistant, corrosion resistant ceramic pan are obtained under the conditions of this
Best performance is got over, and its service life was up to more than 50 years.
Beneficial effect
The present invention provides a kind of wear-resistant, high-low temperature resistant ceramic pan, and its advantage is as follows:
(1), lightweight, hardness is high, good toughness, and micro-ceramic powder can increase the hole inside ceramics, makes ceramics
Light weight is relatively light, moreover it is possible to make hardness and the toughness increase of ceramics, so as to increase its intensity and service life.
(2), wear-resistant, corrosion-resistant, high-low temperature resistant, base substrate is with adding nanoscale silica flour in glaze layer raw material, inside ceramics
Hole is filled up, and increases its intensity, during sintering, part silica flour and nitrogen reaction generation silicon nitride, so that increase that its is wear-resistant,
Corrosion-resistant, high and low temperature resistance, finally increases its service life.
