Appearance quality: The standard requires that the non-stick coating in the pot should be smooth,aluminum nonstick cookware the color, hiding power, and gloss should be basically uniform, no bubbles, no shedding,aluminum nonstick cookware and the coating should be completely hot melted, without obvious dirt, cracks and explosion points. defect.
Handle load strength: The standard requirement for double-handle pot is W=1/2W1+3/2W2,aluminum nonstick cookware and for single-handle pot is W=W1+3W2 (Note: W=load force, Wl=weight of the specimen,aluminum nonstick cookware W2= The maximum water-holding gravity of the test piece.) After the test, the handle bracket is not loose,aluminum nonstick cookware not deformed, and the handle has no cracks.
Base material thickness: The base material of the product should be made of aluminum and aluminum alloy materials that can meet the performance requirements of the product. The minimum thickness of the base material of the frying pan and the wok is 2.0mm and 2.5mm respectively;aluminum nonstick cookware the minimum thickness of the base material of the boiling pan and the milk pan is 1.6mm and 1.8mm respectively.
There are two considerations for specifying the thickness of the base material: one is to consider the product to have a certain strength;aluminum nonstick cookware the other is to protect the non-stick coating. If a non-stick pan is used on a gas stove,aluminum nonstick cookware if the base material is thin, the lateral heat conduction area of the metal at the bottom of the pan will be reduced,aluminum nonstick cookware resulting in uneven heat distribution and hot spots. If these hot spots exceed the tolerance of the coating, aluminum nonstick cookware it will cause permanent damage to the non-stick coating and shorten the service life of the non-stick pan.
