Detailed Description
The technical scheme of the invention is further described below by combining the embodiments.
The method used for sintering the porcelain plate is as follows, which is also the traditional process for sintering the porcelain plate:
namely: the various raw materials are crushed into ceramic slurry in a ball mill, the ceramic slurry is injected into a mould for molding and drying until the moisture content is less than 3%, and the ceramic slurry is sintered for 7 to 9 hours at the temperature of 1180 to 1230 ℃ in a kiln to form the ceramic plate.
The following examples were all based on the above production process.
Example A1
The raw materials used are as follows: 30 kg of kaolinite, 20 kg of quartz, 10 kg of potassium feldspar, 10 kg of albite, 3 kg of talcum, 5 kg of mica, 5 kg of alumina and 5 kg of zinc oxide.
The first porcelain plate of A series is made from the above raw materials, and the first refrigerating element of A series is made from such porcelain plate.
Example A2
The raw materials used are as follows: 50 kg of kaolinite, 30 kg of quartz, 20 kg of potassium feldspar, 20 kg of albite, 5 kg of talcum, 10 kg of mica, 10 kg of alumina and 10 kg of zinc oxide.
The first porcelain plate is made of the above materials, and the second refrigerating element is made of the porcelain plate.

The first porcelain plate of A series is made from the above raw materials, and the third refrigerating element of A series is made from such porcelain plate.
Example B1
On the basis of the above examples A1, A2 and A3, 5 to 10 kg of zirconia and 1 to 3 kg of nickel sesquioxide powder were added to the raw materials.
The raw materials are used to make B1 series porcelain plates, and the porcelain plates are used to make B1 series refrigerating parts.
Example B2
Based on the above examples A1, A2 and A3, 2 to 4 kg of barium sulfate, 5 to 10 kg of manganese dioxide powder and 1 to 2 kg of silver powder (the silver powder is 100 mesh silver powder) were added to the raw materials.
The raw materials are used to make B2 series porcelain plates, and the porcelain plates are used to make B2 series refrigerating parts.
Example B3
1-3 kg of nickel oxide powder and 1-2 kg of silver powder are added to the raw materials based on the above examples A1, A2 and A3.
The raw materials are used to make B3 series porcelain plates, and the porcelain plates are used to make B3 series refrigerating parts.
Example C
On the basis of the above examples A1, A2 and A3, 5 to 10 kg of zirconia, 1 to 3 kg of nickel oxide powder, 2 to 4 kg of barium sulfate, 5 to 10 kg of manganese dioxide powder and 1 to 2 kg of silver powder are added into the raw materials.
The ceramic plate is used to make C-series refrigerating parts.
Local conclusions were drawn by the above examples: it follows that porcelain plates made from the raw materials of the prior art have the disadvantage of being durable; on the basis of the prior art, 5 to 10 parts of zirconium oxide and 1 to 3 parts of nickel sesquioxide powder are added singly, or 2 to 4 parts of barium sulfate, 5 to 10 parts of manganese dioxide powder and 1 to 2 parts of silver powder are added singly, or 1 to 3 kg of nickel sesquioxide powder and 1 to 2 kg of silver powder are added singly, so that the service life of the refrigeration piece is not greatly prolonged by the prepared porcelain plate; only if 5 to 10 parts of zirconia, 1 to 3 parts of nickel sesquioxide powder, 2 to 4 parts of barium sulfate, 5 to 10 parts of manganese dioxide powder and 1 to 2 parts of silver powder are added on the basis of the prior art, refrigeration pieces with longer service life can be produced, so that 5 to 10 parts of zirconia, 1 to 3 parts of nickel sesquioxide powder, 2 to 4 parts of barium sulfate, 5 to 10 parts of manganese dioxide powder and 1 to 2 parts of silver powder are simultaneously added into raw materials.
The reason for this is: the ceramic plate produced in this way has lower shrinkage and expansion rate when the temperature is changed, namely, the expansion of the ceramic plate is smaller when the temperature of the ceramic plate is increased, and the shrinkage of the ceramic plate is smaller when the temperature of the ceramic plate is reduced, so that the grains are less influenced; the millimeter/meter DEG C refers to the extension or contraction length of the porcelain plate with the length of 1 meter when the temperature is increased or decreased by 1 ℃.
Example D
On the basis of the above example C, 4-6 parts of aluminum powder (the aluminum powder is 100 meshes) is also added into the raw materials to obtain a D-series porcelain plate.
The porcelain plate manufactured in this way has the advantage of higher bearing strength.
The bearing strength of the test porcelain plate is that the porcelain plate with a certain length (for example, 10 cm), a certain width (for example, 10 cm) and a certain thickness (for example, 2 mm) is adopted, the two ends of the porcelain plate are padded, the middle part is pressed downwards, the porcelain plate is pressed downwards to break the threshold value of the porcelain plate, and the model of the test porcelain plate is the same as the model of the test porcelain plate.
The above effect is better when 5 parts of aluminum powder is used.
Example E
On the basis of the above example C, 4-6 parts of titanium powder (the titanium powder is 100 mesh titanium powder) is also added into the raw material to obtain E series porcelain plates.
The porcelain plate manufactured in this way has the advantage of higher bearing strength.
The above effect is better when 5 parts of titanium powder is used.
Example F
On the basis of the above example C, 1-2 parts of copper powder (the copper powder is 100 mesh copper powder) is added into the raw material to obtain the ceramic plate of F series.
The porcelain plate manufactured in this way has the advantage of higher bearing strength.
The above effect is better when 1.5 parts of copper powder is used.
Example G
On the basis of the embodiment C, 4-5 parts of aluminum powder, titanium powder and copper powder (all of which are 100 meshes) are added into the raw materials to obtain the G-series porcelain plate.
The porcelain plate made of the porcelain plate has the advantage of higher bearing strength.

the manufacturing method of the porcelain plate of the high-strength refrigerating piece further comprises the steps of firing twice: as shown in FIG. 1, the first firing is carried out by raising the temperature from room temperature to 950-1050 ℃ for 1-1.5 hours, and maintaining the temperature at 950-1050 ℃ for 2-3 hours;
then cooling for the first time, wherein the first cooling is to cool to 400-600 ℃ from the first high temperature for 1-1.5 hours, and the 400-600 ℃ is the first low temperature;
then, performing second firing, wherein the second firing is performed from the first low temperature to 1150-1250 ℃ in 1-1.5 hours, and the second firing is performed for 5-7 hours;
and then carrying out second cooling, wherein the second cooling is carried out after cooling to normal temperature within 1-1.5 hours, so as to prepare the porcelain plate.
The obtained porcelain plate has stronger bearing capacity.
The present invention is not limited to the preferred embodiments, and any person skilled in the art can make some changes or modifications to the equivalent embodiments without departing from the scope of the present invention, but any simple modification, equivalent changes and modifications to the above embodiments according to the technical principles of the present invention are still within the scope of the present invention.
