Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with specific experimental examples.

[0027] The equipment used in the embodiment of the present invention is conventional equipment, and the purity of the raw materials used in the production of anti-explosion enamel meets the requirements of industrial grade, wherein NiO is required to be green nickel oxide, and the purity is Ni≥75%.

[0028] First, according to the component formula shown in Table 1, these several raw materials are pre-mixed and ball-milled dry-milled, and the mixing uniformity is ≥99.5%.

[0029] Table 1

[0030]

[0031] Then mix the components according to the parts by weight shown in Table 2, and the uniformity of mixing is more than or equal to 98%.

[0032] Table 2

[0033]

[0034] Continued Table 2

[0035]

[0036] In table 2, the composition content (mass percentage) of potassium feldspar is: 8.2% K 2 O, 2.2% Na 2 O, 15% Al 2 o 3 , 73.5% SiO 2 , P...

Abstract

The invention belongs to the technical field of porcelain glaze of enamel, and particularly relates to a formula of cracking preventing porcelain glaze of enamel and preparation of the cracking preventing porcelain glaze of the enamel. After the cracking preventing porcelain glaze is coated on an enamel steel plate with porcelain about to be cracked and is baked, an enamel product comprising the cracking preventing porcelain glaze cannot be cracked. The cracking preventing porcelain glaze comprises SiO2, B2O3, Al2O3, Na2O, K2O, Li2O, CaO, TiO2, MgO, BaO, Co2O3, NiO, Fe2O3, MnO2 and CuO. After the components are uniformly mixed, uniformity of mixture of the components is larger than or equal to 98%. After the mixture is smelted in a smelting furnace at the temperature of 12200C-12800 DEG C, glass fibers are drawn, are discharged when each mile of the glass wires has 2-3 joints, and then are cooled and crushed. After the cracking preventing porcelain glaze is coated on the enamel steel plate with the porcelain about to be cracked, the enamel product comprising the cracking preventing porcelain glaze cannot be cracked.

Description

technical field [0001] The invention belongs to the technical field of enamel enamel, and in particular relates to an enamel anti-explosion enamel for enamel products that is coated on an enamel steel plate with a tendency to enamel and fired, and the enamel products produced will not produce enamel explosion and enamel. preparation. Background technique [0002] After the existing enamel enamel coating at home and abroad is fired on the enamel steel plate with a tendency to explode, the enamel products made will have fish scale-like explosions, and some of these defects will occur immediately after firing and cooling to room temperature. , some are placed in the warehouse for several weeks, or even months before they are produced. Every year, the scale-like explosive porcelain causes huge economic losses to the enamel manufacturers. This is the most troublesome problem facing the enamel industry, and it is also the technical field of enamel that has not been solved for qui...
