What are the advantages and disadvantages of the sandblasting electrolytic process and pure polishing of the inner wall of the thermos cup?

Hello everyone, "Dong Dong Talk Cup" is here. In the process of producing thermos cups and using them, the inner wall processing technology is an important factor affecting the thermal insulation performance, safety and aesthetics of the cup. http://www.zhanyict.com/en/ProductsDetail-VB-10254.htmlAt present, the common processing technologies for the inner wall of thermos cups are sandblasting electrolysis technology and pure polishing technology. Today, the editor will share with friends the advantages and disadvantages of these two processes in comparison.

What are the advantages of sandblasting electrolytic process?

Improve the roughness of the cup wall: The sandblasting process can form a uniform rough surface on the inner wall of the thermos cup, increase the surface area, http://www.zhanyict.com/en/ProductsDetail-VB-10254.htmland thus more effectively improve the insulation effect.

Beautiful effect: The inner wall after electrolysis treatment has uniform color. During the electrolysis process, the inner wall can present different visual effects such as mirror, highlight, matte, dull, etc. by adjusting the time and the ratio of the electrolyte.

Strong anti-corrosion: A dense oxide film can be formed during the electrolysis process, http://www.zhanyict.com/en/ProductsDetail-VB-10254.htmlwhich effectively blocks moisture and pollutants and improves the corrosion resistance and durability of the cup.

What are the disadvantages of the electrolytic sandblasting process?

Relatively high cost: Compared with traditional polishing process, sandblasting and electrolytic process have higher equipment and operation costs. http://www.zhanyict.com/en/ProductsDetail-VB-10254.htmlHere, the editor would like to emphasize that traditional polishing process refers to ordinary polishing, with fewer polishing steps and simple polishing fineness.

Difficulty of cleaning: Due to the rough surface, some tiny food particles and stains may adhere to the inner wall and are not easy to clean.

What are the advantages of pure polishing process?

Smooth surface: The polishing process makes the inner wall of the thermos cup very smooth, greatly reducing the possibility of food residue and bacterial growth.

Easy to clean: http://www.zhanyict.com/en/ProductsDetail-VB-10254.htmlThe smooth surface is easy to clean, and stains and residues inside the cup can be quickly removed with ordinary cleaning tools.

Relatively low cost: Compared with the sandblasting electrolytic process, the equipment and production costs of the pure polishing process are lower. However, as labor costs are getting higher and higher, the cost of the polishing process will be higher if the inner wall has to achieve a mirror effect.

What are the disadvantages of pure polishing process?

The thermal insulation effect is slightly worse: the surface area of the smooth inner wall is relatively small, and the thermal insulation effect will be worse than the electrolytic process. http://www.zhanyict.com/en/ProductsDetail-VB-10254.htmlHowever, as the polishing effect requirements are higher, the defective rate will be higher than the electrolytic process.

Easy to scratch: Although the polished surface is smooth, it is also easily scratched by hard objects, affecting the appearance.

In general, the sandblasting electrolytic process and the pure polishing process have their own advantages and disadvantages. http://www.zhanyict.com/en/ProductsDetail-VB-10254.htmlThe choice of which process depends on the product demand and market positioning.
