Abstract
The invention discloses an aluminum alloy non-stick pan with a ceramic coating. The aluminum alloy non-stick pan comprises an aluminum alloy pan body with a flat pan bottom. Regularly-arrayed protruding bodies are arranged on the surface of the flat pan bottom, wherein the protruding bodies and the pan body are formed in a pressed mode at a time. A super-hard non-stick silicon ceramic coating is arranged on the inner surface of the pan body and comprises a graphite layer and the metal ceramic coating, wherein the thickness of the graphite layer ranges from 5 micrometers to 8 micrometers, and the thickness of the metal ceramic coating ranges from 10 micrometers to 30 micrometers. Because the regularly-arrayed protruding bodies are formed on the surface of the pan bottom in a pressed mode, the heating area of the pan bottom is enlarged, heat energy reflection is reduced, and the heat energy utilization ratio and efficiency are improved. The Ti-based metal ceramic coating arranged on the inner surface of the pan body has no pollution on food at a high temperature and can replace Teflon non-stick coatings.
Description
Technical field
The invention belongs to kitchen utensils field, relate to a kind of aluminium alloy non-stick pan, be specifically related to a kind of aluminium alloy non-stick pan with ceramic coating.
Background technology
Because frying pan, slaughterhouse or pan are the topmost utensil of conditioning food, closely bound up with people's healthy and daily life, therefore, that the good pan of quality requires to be heated is average, dish non-stick pan during cooking, simultaneously can be antirust anti-anti-corrosion, so just can reach user's requirement.
Current cooking food pan used, great majority adopt stainless steels or aluminium alloys to make, and the pan that uses aluminium alloy to make has feature lightweight, cheap for manufacturing cost, so that the pot occurring on market is essentially aluminum alloy materials is made.
Existing non-stick pan, all in the bottom of a pan, apply the coating of one deck " Teflon ", " Teflon " is the general name of fluorine resin, comprise polytetrafluoroethylene (PTFE), perfluoroethylene-propylene and various fluorinated copolymer, because these compounds have the advantages such as high temperature resistant, low temperature, self lubricity, chemical stability, therefore be widely used in non-sticking cooking utensils, waterproof ventilative material (as waterproof clothes), leather, automobile component, and micro-wave oven popcorn bag etc.
Perfluorooctanoic acid is the necessary additive in the process of production Teflon, although there is no vestige in finished product, at high temperature still may decompose.Research discovery, Teflon at high temperature, can discharge tens kinds of pernicious gases, causes the animal dead of some respiratory tract sensitivities.The perfluorooctanoic acid of stable chemical nature enters after natural environment and human body, and meeting long-term existence, decomposes very slow.Research shows, low dosage perfluorooctanoic acid not only appears in river, ocean and soil, is also present in people's blood.Because this artificial compound has been proved carcinogenesis and other adverse consequences in zoopery, if be extensively present in natural environment and human body, consequence is troubling.Therefore, need to find the non-stick steel of brand-new coating structure.
Ceramic material has use widely in fields such as national defence, machinery, chemical industry, metallurgy, electronics.Wherein, it is high that titanium carbide TiC pottery has fusing point, good heat conductivity, and hardness is large, and chemically stable is good, is not hydrolyzed, and high-temperature oxidation resistance is good, and thermal coefficient of expansion is little, anti-thermal shock and the advantage such as chemical resistance is strong, is the focus of countries in the world material scholar research always.
