How durable is the thermos cup after polishing?
Polishing can significantly improve the durability of the thermos cup, mainly in the following aspects:
Surface smoothness and cleanliness
Reduce stain residue: The surface of the thermos cup after polishing is very smooth, and it is not easy to retain food particles and stains, which is more convenient to clean, thus extending the service life of the thermos cup.
Prevent bacterial growth: The smooth surface reduces the possibility of bacterial growth, maintains the hygiene of the thermos cup, and further improves its durability.
Abrasion resistance and corrosion resistance
Improve wear resistance: Polishing makes the surface of the thermos cup harder, which can resist the wear and scratches in daily use, and is not prone to scratches and wear, thus maintaining the appearance and performance of the thermos cup.
Enhance corrosion resistance: The polished surface can better resist corrosion, especially in humid environments, reducing the risk of rust and corrosion, and further improving the durability of the thermos cup.
Insulation performance
Improve sealing: Polishing can remove the uneven parts of the surface of the thermos cup, so that the cup lid and the cup mouth are better sealed, reducing heat loss, thereby improving the insulation effect.
Maintain the integrity of the vacuum layer: The polished surface is smoother, which helps to maintain the integrity of the vacuum layer between the inner and outer shells of the thermos cup, further improving the insulation performance.
Aesthetics
Improve the appearance quality: The polishing process makes the surface of the thermos cup smoother and flatter, with a higher gloss, which improves the aesthetics of the product and makes it more popular in daily use.
Enhance the decorativeness: The surface of the polished thermos cup can be further decorated, such as electroplating or spraying, to increase the decorativeness and personalization of the product.
Limitations
Easy to scratch: Although the polishing process increases the hardness of the surface, the polished surface may still be scratched by hard objects, affecting its aesthetics.
Maintenance requirements: The polished thermos cup requires more meticulous maintenance to maintain its surface smoothness and gloss, and avoid using rough cleaning tools and irritating detergents.
In summary, polishing has a significant effect in improving the durability of the thermos cup, but it is also necessary to pay attention to its limitations and take appropriate maintenance measures to maintain its performance and appearance.
