Purple sand glass ceramic bowl and preparation process thereof

Abstract

The invention discloses a purple sand glass ceramic bowl, belonging to the technical field of tableware. The purple sand glass ceramic bowl is composed of the following components in parts by weight: 40-70 parts of silicon dioxide, 10-20 parts of Suzhou soil, 3-8 parts of titanium dioxide, 10-15 parts of purple sand, 0.5-1 part of vermiculite powder, 2-4 parts of shell powder, 0.2-2 parts of copper oxide, 2-4 parts of lignin, 0.5-1 part of carbon nanotube, 2-5 parts of graphene nanoplatelets, 1-3 parts of sulfate, 0.1-0.8 part of tin oxide, 3-5 parts of dolomite, 3-7 parts of nano silicon carbide, 0.5-2 parts of stainless steel fiber and 0.1-0.5 part of silver fiber. By virtue of special preparation on raw materials, the prepared bowl is smooth in surface and good in strength, cannot be broken when falling off and does not scald the hand, and compared with a conventional process, a process for preparing the purple sand glass ceramic bowl disclosed by the invention is short in time, low in energy consumption, good in product quality and free of toxic or harmful substance residue.

Description

technical field [0001] The invention relates to the technical field of tableware, in particular to a purple sand glass ceramic bowl and a preparation process thereof. Background technique [0002] Since humans have used metal pots to cook dishes, the cooking spatulas used by our ancestors for generations basically use iron shovels. According to the concept of metallurgy, shovels belong to low-carbon steel, that is, an alloy composed of elemental iron (Pe) and trace carbon (C). As we all know, ordinary steel is very easy to rust in the atmosphere we live in. This rusting belongs to electrochemical corrosion. The oxidized iron rust spots formed on the surface of ordinary carbon steel continue to expand, and the speed is very fast. The occurrence of galvanic corrosion is an insurmountable defect of ordinary steel exposed to the air. Moreover, rust mixed into the dish spoils the taste of the dish. In addition, its aesthetics is also poor, and the common people call it "blac...

Problems solved by technology

Galvanic corrosion is an insurmountable defect of ordinary steel exposed to the air

Moreover, the rust mixed with the dish will damage the taste of the dish

In addition, its aesthetics is also poor, and the common people call it "black shovel".

Today's manufacturers of stainless steel cooking spatulas and users who use them are unaware of the carcinogenicity and allergenicity of chromium and nickel in stainless steel cooking spatulas that enter the human body along with the dishes after they are ground during the cooking process
