Problems solved by technology

[0003] However, when the enamel inner tank is used, it has to withstand the sudden change in the pressure of the cold and hot water in and out of the water pipe and the sudden change in the temperature difference in an instant, which can easily induce cracks in the enamel layer and even cause damage to the enamel layer, and such cracks or damage are especially easy Occurs at the lap weld of the liner head and barrel body
In addition, due to the poor toughness of the enamel layer during transportation, the existing enamel liner is also very prone to collision and cracking, which affects the service life of the enamel liner

Abstract

The invention discloses high-toughness enamel glaze. The enamel glaze is prepared from the following components in parts by weight: 40-50 parts of silicon dioxide, 15-25 parts of titanium dioxide, 5-15 parts of potassium oxide, 10-20 parts of sodium oxide, 1-5 parts of lithium oxide, 2-4 parts of calcium fluoride, 6-12 parts of vanadium pentoxide, 1-3 parts of tungsten carbide and 5-10 parts of aluminum oxide and zirconium dioxide. According to the enamel glaze, by means of the composition, the toughness of the enamel glaze can be greatly improved, meanwhile, the defect that ceramic cracks arecaused due to collision can be overcome, and therefore, the enamel glaze has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of enamel glazes, in particular to a high-toughness enamel glaze. Background technique [0002] The enamel water heater liner originated in the United States. The enamel liner is a liner with enamel coating sintered on the inner surface. The enamel liner can be used as an enamel water tank after foaming. It can be applied to solar water heaters, air energy water heaters and electric water heaters. . The enamel inner tank is replacing other inner tanks and becoming the main force of the water heater inner tank because of its superior performance in anti-corrosion, pressure-bearing durability, anti-absorption, and clean water. [0003] However, when the enamel inner tank is used, it has to withstand the sudden change in the pressure of the cold and hot water in and out of the water pipe and the sudden change in the temperature difference in an instant, which can easily induce cracks in the enamel layer and ev...
