Heat-resistant and environmentally friendly glaze for tableware

Abstract

The invention mainly relates to the technical field of ceramic glaze processing, and discloses a heat-resistant and environmentally friendly glaze for tableware, which is made of the following raw materials: silicon dioxide, zinc oxide, iron nitride, graphene, aluminum oxide, di Niobium, vanadium boride, cobalt oxide, white carbon black, salt, antibacterial agent; rich in raw materials, enhance the heat resistance and wear resistance of the glaze, the resistance to rapid change in cold and heat reaches 193.1K, and the biaxial bending strength increases by 58.1%. Prevent the glaze layer from falling off after bumping, prolong the service life, and the antibacterial time can be as long as 10 years in normal use; adding salt and antibacterial agent can reduce air bubbles, increase the fineness, density and fluidity of the enamel, and match the expansion coefficient. Keep the enamel smooth, the antibacterial rate reaches 66.1%, after short-term high-temperature firing, maintain the original color of ceramic products, strong stability, corrosion resistance, save production costs by 17.8%, safe and environmentally friendly, green and healthy, free of lead and cadmium dissolution, Health and Environmental Protection.

Description

technical field [0001] The invention mainly relates to the technical field of ceramic glaze processing, in particular to a heat-resistant and environment-friendly glaze used for tableware. Background technique [0002] Glaze is a kind of silicate. The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperature. The temperature drops When forming a thin glassy layer on the surface of ceramics, it can increase the mechanical strength, thermal stability, dielectric strength of the ceramics and prevent the erosion of liquids and gases. effect. [0003] Tableware is often exposed to high temperatures and is often easily bumped during the scrubbing process. Tableware is required to have good heat resistance and wear resistance, and tableware is in direct contact with food. Therefore, the quality of tableware directly affects people's health...

[0003] Tableware is often exposed to high temperatures and is often easily bumped during the scrubbing process. Tableware is required to have good heat resistance and wear resistance, and tableware is in direct contact with food. Therefore, the quality of tableware directly affects people's health. With the development of society With the progress and the improvement of people's living standards, people's requirements for tableware are getting higher and higher. Not only are tableware required to be heat-resistant and durable, but they should also be healthy and environmentally friendly. However, it has been detected that lead and Cadmium content exceeds the standard, causing great harm to human health
