Application of green carborundum GC in non-stick pan coatings
As a high-performance ceramic material, green carborundum GC has significant advantages in the application of non-stick pan coatings, which are mainly reflected in the following aspects:
I. Core performance advantages
High hardness and wear resistance
The hardness of green carborundum GC is second only to diamond, which can significantly improve the scratch resistance of the coating, reduce the wear of the coating by cooking tools (such as spatulas), and extend the service life of non-stick pans.
High temperature stability
Green carborundum GC can still maintain stable physical and chemical properties at high temperatures, and is suitable for high temperature environments during cooking (such as frying and stir-frying), avoiding the failure of the coating due to thermal expansion or oxidation.
Chemical inertness and corrosion resistance
It has strong resistance to corrosive substances such as acids, alkalis, and salts, preventing the coating from falling off due to erosion by food or detergents.
Reduced porosity
Adding Green carborundum GC can improve the density of polytetrafluoroethylene (PTFE) coatings, reduce the pores generated during sintering, and reduce the risk of corrosion of metal substrates caused by salt water penetration.
Ⅱ. Specific application direction in non-stick pan coatings
Enhance the mechanical strength of the coating
Make up for the defect of insufficient high-temperature strength of PTFE resin, improve the coating’s ability to resist pressure and deformation, and reduce scratches or peeling of the coating caused by frequent use.
Optimize coating uniformity
The green carborundum GC micropowder has a concentrated particle size distribution, which helps to form a uniform and dense coating surface, improve adhesion and improve the appearance texture.
Synergistically improve functionality
When combined with silicone coatings, it can alleviate high-temperature re-adhesion and enhance hardness;
In fluorocarbon coatings, it further improves wear resistance and washability.
Ⅲ. Environmental protection and safety
Green carborundum GC micropowder does not contain carcinogens, meets the safety standards of food contact materials, and does not require special hazard identification;
By reducing coating wear and corrosion, the frequency of non-stick pan replacement is reduced, which is in line with the concept of environmental protection.
IV. Current market application status
Currently, green carborundum GC has been widely used in mainstream non-stick pan coating formulas such as silicone coatings and fluorocarbon coatings. Its addition ratio and micropowder size (such as JIS1200) need to be adjusted according to the specific process to achieve a balance between performance and cost.
Through the above applications, green carborundum GC effectively solves the problem of easy wear and short life of traditional non-stick pan coatings, and becomes one of the key materials for improving the performance of cooking utensils.
