Embodiment 1
[0025] The steps of the method for producing the first full-body illusion microcrystalline jade plate by using a roller kiln are as follows:
[0026] (1) Prepare a glass-ceramic frit produced by a conventional process, the chemical composition of which is (percentage by weight):
[0027]
[0028] Above-mentioned rare earth element selects praseodymium oxide for use;
[0029] The preparation method step of glass-ceramic frit is:
[0030] ①According to the above formula, mix various minerals evenly;
[0031] ② Melting in the melting furnace for 1 to 5 hours and completing the physical and chemical reactions to form glass-ceramic melt;
[0032] ③The glass-ceramic melt is water-quenched into small particles, and after being filtered dry, it is bagged for later use to obtain a green glass-ceramic frit;
[0033] (2) Preparation of color development aids:
[0034] ①According to the following formula, various mineral raw materials are batched (percentage by weight):
[0035] ...
Embodiment 2
[0041] The method steps for producing the second kind of full-body illusion microcrystalline jade plate by using a roller kiln are as follows:
[0042] (1) Prepare the glass-ceramic frit produced by the conventional process, its chemical composition is (percentage by weight):
[0043]
[0044] The frit preparation method is the same as in Example 1.
[0045] (2) Preparation of color development aids:
[0046] ①According to the following formula, various mineral raw materials are batched (percentage by weight):
[0047]
[0048] ②After wet ball milling, the fineness is 250 mesh sieve and the remaining O.2~1.2%;
[0049] ③ Stir in the stirring tank for at least 12 hours, and measure the viscosity with a Tuo's viscometer for 50-75 seconds;
[0050] (3) Making a kind of kiln furniture is the same as that in Embodiment 1.
[0051](4) Use an automatic distributing device to distribute the above-mentioned glass-ceramic frits on the refractory backing plate according to a p...
Embodiment 3
[0053] The steps of the method for producing the third kind of full-body illusion microcrystalline jade plate by using a roller kiln are as follows:
[0054] (1) Prepare two kinds of glass-ceramics frits produced by conventional processes, and their chemical components are respectively (weight percent):
[0055] 1# frit
[0056]
[0057] Above-mentioned rare earth element selects erbium oxide for use;
[0058] 2# frit
[0059]
[0060] The above two frit preparation methods are the same as in Example 1.
[0061] (2) Preparation of color development aids:
[0062] ①According to the following formula, various mineral raw materials are batched (percentage by weight):
[0063]
[0064] ②After wet ball milling, the fineness is 250 mesh sieve and the remaining O.2~1.2%;
[0065] ③ Stir in the stirring tank for at least 12 hours, and measure the viscosity with a Tuo's viscometer for 60-100 seconds;
[0066] (3) Making a kind of kiln furniture is the same as that in ...
