Embodiment 1

[0045] (1) Weigh the feedstock according to the mass of the following components:

[0046] 8.4kg of environmentally friendly waste, 17.7kg of quartz, 13.6 kg, potassium longite 12.7kg, sodium carbonate 21.1kg, calcium carbonate 7.6kg, bicarbonate 4.4kg, aluminum hydroxide 2.2 0.5 kg, iron oxide 3.2 Kg, manganese oxide 1.0kg, copper oxide 0.28 kg, nickel oxide 0.9kg, fluorite powder 4.7kg;

[0047] (2) mix the above raw materials and mix;

[0048] (3) Add a mixed material to the melt furnace, fuse under pure oxygen conditions, and the fuse temperature is controlled at 1250 ± 10 ° C;

[0049] (4) Remove the borosilicate vitreous to obtain a borosilicate glass, the molten borosilicate glass is pulverized, and the glass wire is pulled into a glass wire to detect, and the test requirement is: within 1 meter of the glass wire. The 2-3 sections are melted;

[0050] (5) Put the fused borosilicate glass is quenched (water to quench), that is, the product is obtained.

Embodiment 2

[0052] This embodiment is substantially the same as the preparation process of Example 1, and the difference is:

[0053] The mass of each component in step (1) is: 9.2kg of environmentally friendly waste, 18.5kg of quartz, 14.3kg, potassium lactar, 12.7kg of potassium, 21.1 kg of sodium carbonate, calcium carbonate 4.4 kg, hydrogen Alumina 2.4kg, magnesium carbonate 0.5 kg, iron oxide 3.0 kg, manganese oxide 0.28 kg, nickel oxide 0.9kg, fluorite powder 4.7kg.

Embodiment 3

[0055] This embodiment is substantially the same as the preparation process of Example 1, and the difference is:

[0056] The mass of each component in step (1) is: 9.7kg of environmentally friendly waste, 19.4kg of quartz, 15.8kg of zero water borax, 12.7kg of potassium, 21.1 kg of sodium carbonate, calcium carbonate 4.4 kg, hydrogen carbonate Alumina 2.4kg, magnesium carbonate 0.5 kg, iron oxide 3.0 kg, manganese oxide 0.28 kg, nickel oxide 0.9kg, fluorite powder 4.7kg.

Abstract

The invention discloses a steel plate enamel ground coat using environment-friendly waste to replace nitrate and a preparation method thereof. The formula of the ground glaze comprises the following components in parts by mass: 8-10 parts of environment-friendly waste, 17-20 parts of quartz, 13-16 parts of anhydrous borax, 20-22 parts of sodium carbonate, 12-13 parts of potassium feldspar, 7-8 parts of calcium carbonate, 4-5 parts of barium carbonate, 0.4-0.6 part of magnesium carbonate, 2-2.5 parts of aluminum hydroxide, 3-4 parts of ferric oxide, 0.8-1.0 part of manganese oxide, 0.2-0.4 part of copper oxide, 0.8-1.0 part of nickel oxide and 4.5-5 parts of fluorite powder. The raw materials are uniformly mixed according to the proportion and are melted at 1250 + / -10 DEG C under the condition of pure oxygen, and the firing temperature of the finished product is 800-860 DEG C. The formula does not contain nitrate, and the major technical problem that nitrogen oxide (NOx) gas generated in the production process of the existing steel plate enamel ground glaze is discharged to pollute the environment is fundamentally solved.

Description

Technical field [0001] The present invention belongs to the field of enamel, and in particular to a steel plate enamel glaze and preparation method for replacing nitrates with environmentally friendly waste. Background technique [0002] Enamel porcelain glaze is mainly based on refractory raw materials such as stone, quartz, sodium nitrate, sodium nitrate, potassium nitrate, sodium nitrate, sodium nitrate, and the characteristic raw materials such as non-ferrous metal oxides, in accordance with a certain proportion, high temperature melting, drastically cooled into granular or sheets The borosilicate glass is prepared. [0003] Enamel glaze introduced nitrate (sodium nitrate, potassium nitrate, etc.) as an oxidant and flux, is already a consensus of industry, and is an indispensable enamel glaze raw material in traditional enamel theory. So far, there is no safe, colorless, and reasonable existing oxidative nitrate and help melt raw materials. Long-term production practice demon...
