What is the purpose of coated insulation cups


The insulation cup coating is mostly a thin silver layer formed by aluminum plating inside the interlayer, with the aim of generating a silver mirror reaction to reduce radiation heat dissipation. If a little is lost, it will not have any impact. However, if a lot is lost, it is recommended to replace it. If the insulation layer coating falls off, the insulation cup no longer has insulation effect.
The coating can also serve as a waterproof stain, making it easy to clean. The falling of the coating will not be related to water, but it will affect the insulation time of the water.
The inner liner of the insulation cup is generally made of stainless steel material. The inner liner material of the insulation cup should be food grade 304 or 316 stainless steel. 304 stainless steel has corrosion resistance and high temperature resistance, and is widely used in the food industry. 316 stainless steel has better performance than 304 stainless steel, and is widely used in medical devices.
In daily life, it is generally enough to choose a 304 stainless steel insulated cup, which is sufficient to ensure the health of drinking water.
