Interpretation Of Non-stick Pan Standards
1. Appearance quality
The standard requires that the non-stick coating in the pot should be smooth, the color, covering power, and gloss should be basically uniform, without bubbles, and not falling off.
2. Handle load strength
The standard requirement for the double-handled pot is W=1/2W1+3/2W2, while for the single-handled pot it is W=W1+3W2 (Note: W=load force, Wl=weight of the specimen, W2=maximum capacity of the specimen Water gravity.) After the test, the handle bracket is not loose, not deformed, and the handle has no cracks.
3. Thickness of base material
The base material of the product should choose aluminum and aluminum alloy materials that can meet the performance requirements of the product. The minimum thickness of the base material of frying pan and frying pan is 2.0mm and 2.5mm respectively; the minimum thickness of base material of cooking pot and milk pot is 1.6mm and 1.8mm respectively. There are two considerations in specifying the thickness of the base material: one is to consider that the product has a certain strength; the other is to protect the non-stick coating. A non-stick pan is used on a gas stove. If the base material is thin, the lateral heat conduction area of the metal at the bottom of the pan will be reduced, resulting in uneven heat distribution and hot spots. These hot spots can cause permanent damage to the non-stick coating and shorten the life of the non-stick pan if they exceed the tolerance of the coating.
4. Thickness of non-stick coating
The standard requires that the average thickness of frying pans and frying pans is greater than or equal to 25 microns; the average thickness of cooking pots and milk pans is greater than or equal to 20 microns. This is an important indicator of non-stick pans and will affect the service life and performance of non-stick pans. In addition, the surface of the non-stick pan needs to be sandblasted before coating to increase the surface roughness and increase the adhesion, thereby increasing the adhesion fastness and scratch resistance.
5. Scratch resistance
This is an index to test the ability of the coating to resist scratches by various hard substances and the hardness, curing degree and adhesion of the coating itself.
6. Not sticky
Non-stick is an important indicator of non-stick pans, which is related to the performance of the coating itself and the quality of coating curing. According to the standard, wipe the surface of the non-stick coating with a soft cloth sticking with vegetable oil, wash it with warm water and detergent, then wash it with clean water, dry it and conduct the omelet test, so as to identify the non-stick pan and non-stick pros and cons.
