Abstract

The invention discloses an energy-saving glass lining cover coat based on mill addition hyperfin ZrO2 powder as reinforcer, which consists of clinker clew and mill addition material, wherein the clinker clew includes 45-5% SiO2+B2O3, 7-12% Na2O+K2O, 12-16% MgO+CaO+BaO, 3. 5-6% Li2O, 1-2% CoO,6-15% ZrO2+Al2O3+TiO2; the mill addition material contains 40-60% zircon powder at 400-500 order and 3-5% suspending agent clay. The glass phase is main component of regular glass lining cover coat, which changes the structure of ceramic glaze after adding the hyperfine ZrO2 powder to harden the glass lining with more abrasion proof. The invention leads Li2O to reduce the softening point of cover coat clinker clew because the hyperfine ZrO2 powder mill addition is added into the glass lining cover coat to increase the sintering temperature, which makes the sintering temperature of cover coat nearly approach the temperature of regular glass lining cover coat.

Description

technical field [0001] The invention relates to a glass-lined glaze, in particular to a grinding and adding ultrafine ZrO 2 Energy-saving glass-lined glaze with powder as reinforcing agent. Background technique [0002] The so-called glass-lined glaze is an enamel glaze that is resistant to strong acid corrosion. Because its formula and melting process are close to glass, it is called glass-lined glaze. Conventional glass-lined glaze is close to sodium-aluminum-titanium-zirconium-boron-silicate glass, and a small amount of colorant is added. [0003] The formula of conventional glass-lined surface glaze is composed as follows (percentage by weight): [0004] 1. Frit [0005] Matrix agent: SiO 2 +B 2 o 3 =70~76 [0006] Flux: Na 2 O+K 2 O=14~18 MgO+CaO=3~5 [0007] Colorant: CoO+MnO=1~2 [0008] Refractory composition: ZrO 2 +Al 2 o 3 +TiO 2 =5~10 [0009] 2. Grinding material: its composition is based on the weight of the glaze block as 100 [0010] Suspend...
