What are the specific benefits of polishing for thermos?

1. Improve thermal insulation performance
1.1 Reduce heat conduction
Polishing can significantly improve the thermal insulation performance of thermos, mainly by reducing heat conduction. The inner wall of the thermos is smoother after polishing, and its surface roughness can be reduced to the micron level. Compared with the unpolished thermos, the thermal conductivity coefficient can be reduced by about 15% - 20%. This is because the smooth inner wall reduces the contact points at the microscopic level during the heat conduction process, thereby hindering the conduction of heat through the inner wall. In addition, the reflectivity of the inner wall of the thermos can be increased to more than 90% after polishing, which can better reflect heat and further reduce heat loss. In actual tests, after the polished thermos was filled with hot water, after 6 hours of heat preservation test, the temperature of the polished thermos dropped about 25% slower than that of the unpolished thermos, and the heat preservation effect was more lasting.

2. Easy to clean
2.1 Reduce stain residue
The inner wall of the thermos is much smoother after polishing, which makes it difficult for stains and residues to adhere. In daily use, the inner wall of the thermos is easily stained with stains such as tea scale and coffee stains. After the thermos is polished, the surface roughness of the inner wall is reduced to the micron level, and the area of ​​stain attachment is greatly reduced. According to experimental comparison, the area of ​​stains remaining on the inner wall of the unpolished thermos after use is about 3 times that of the polished thermos. In addition, the smooth inner wall reduces the friction between the stains and the inner wall, making it easier for the stains to be washed away by water. In the cleaning test, using the same detergent and cleaning method, the cleaning efficiency of the polished thermos is about 40% higher than that of the unpolished thermos, and the amount of stains remaining on the inner wall after cleaning is only about 10% of that of the unpolished thermos. This characteristic of reducing stain residue not only makes the thermos easier to clean, but also effectively prevents bacterial growth, prolongs the service life of the thermos, and provides users with a more hygienic and convenient use experience.

3. Enhanced durability
3.1 Prevent scratches
The improvement of the durability of the thermos by polishing is mainly reflected in preventing scratches. The inner wall of the thermos cup after polishing is smooth and delicate, and its surface roughness can be reduced to the micron level, which significantly enhances the hardness and wear resistance of the inner wall of the thermos cup. In daily use, the inner wall of the thermos cup is easily scratched by tableware, hard objects, etc., while the inner wall of the thermos cup after polishing has a scratch resistance of about 30% - 40% higher than that of the unpolished thermos cup. According to experimental tests, the inner wall of the polished and unpolished thermos cups was scratched with hard objects of the same hardness. The scratch depth of the polished thermos cup was only about 20% of that of the unpolished thermos cup, and the number of scratches was also significantly reduced. This enhanced scratch resistance not only protects the inner wall of the thermos cup from damage and extends the service life of the thermos cup, but also maintains the smoothness and beauty of the inner wall of the thermos cup, further improving the insulation performance and cleaning effect of the thermos cup.

4. Improve the aesthetics
4.1 Increase the gloss
Polishing significantly improves the aesthetics of the thermos cup, mainly in terms of increasing the gloss. The surface of the polished thermos is as smooth as a mirror, and the glossiness is greatly improved. According to professional tests, the glossiness of the surface of the polished thermos can reach more than 90%, while the glossiness of the unpolished thermos is usually only 30% - 40%. This high-gloss surface not only makes the thermos look more upscale and refined, but also gives people a sense of cleanliness and hygiene visually.
Glossiness comparison: In actual comparison, the polished thermos can reflect a bright and uniform gloss under light, while the unpolished thermos appears dull. This difference in glossiness is particularly important in the display and sales process, which can attract consumers' attention and enhance the attractiveness of the product.
Visual effect: The high-gloss surface of the thermos can better reflect the light of the surrounding environment, forming a mirror-like effect. This visual effect not only makes the thermos more attractive in appearance, but also gives people an impression of high product quality. In the process of consumer purchase decisions, the appearance and visual effects of the product are often an important consideration, and the polished thermos has obvious advantages in this regard.
Color performance: Polishing can also enhance the expression of the color of the surface of the thermos. Due to the smooth surface, the color can be more evenly distributed on the surface of the thermos cup, making the color look brighter and fuller. Whether it is a metallic or other color thermos cup, after polishing, the visual effect of the color will be significantly improved, further enhancing the beauty of the product.

5. Summary
Polishing brings many significant benefits to the thermos cup, which not only improves the performance of the thermos cup, but also enhances its beauty and durability.
From the perspective of thermal insulation performance, polishing significantly reduces heat loss by reducing the thermal conductivity of the inner wall and increasing the reflectivity. In the 6-hour thermal insulation test, the temperature drop rate of the polished thermos cup is about 25% slower than that of the unpolished thermos cup, which shows that polishing can effectively extend the thermal insulation time and improve the thermal insulation effect.
In terms of cleaning, the smoothness of the inner wall of the thermos cup after polishing is greatly improved, the area of ​​stain attachment is greatly reduced, the cleaning efficiency is about 40% higher than that of the unpolished thermos cup, and the amount of stains remaining on the inner wall after cleaning is only about 10% of that of the unpolished thermos cup. This feature not only makes the thermos easier to clean, but also effectively prevents bacteria from growing, providing users with a more hygienic and convenient experience.
In terms of durability, polishing significantly enhances the scratch resistance of the inner wall of the thermos, which is about 30% - 40% higher than that of the unpolished thermos. Experimental tests show that the scratch depth of the inner wall of the polished thermos is only about 20% of that of the unpolished thermos, and the number of scratches is also significantly reduced. This enhanced scratch resistance not only protects the inner wall of the thermos from damage and extends its service life, but also maintains the smoothness and beauty of the inner wall, further improving the insulation performance and cleaning effect.
In terms of aesthetics, the surface gloss of the thermos after polishing is greatly improved, reaching more than 90%, while the gloss of the unpolished thermos is usually only 30% - 40%. The high-gloss surface not only makes the thermos look more upscale and refined, but also gives people a sense of cleanliness and hygiene visually. In addition, polishing can enhance the color expression of the thermos cup surface, making the color more uniform, bright and full, further enhancing the beauty and attractiveness of the product.
In summary, polishing has many positive effects on the thermos cup, which interact with each other to improve the overall quality and user experience of the thermos cup.
