Which spraying process is more wear-resistant for stainless steel thermos cups: ordinary paint, ceramic paint, or plastic powder?


There are many surface treatment processes for stainless steel water cups, which have been mentioned in many previous articles, so I will not repeat them here. Today I will mainly talk about the comparison of spraying process materials on the surface of stainless steel water cups.

Currently, the common stainless steel water bottles on the market are sprayed on the surface with ordinary paints, similar to car-specific metal paints, high-temperature resistant paints, hand paints, ceramic paints, plastic powders, etc. We often encounter some selection difficulties in our daily work. Customers are confused about which spray material should be used for the final surface of the customized water cup in terms of presentation effect, cost, and wear resistance. The following is as brief as possible to introduce to you. I hope it will be helpful to you in customizing water cups. If you like the content of our articles, please pay attention to our website. We will regularly and on time share the life represented by water cup use, water cup production, water cup selection, etc. Content related to daily necessities involves a lot of professional knowledge. Some of the work on how to judge the value and quality of water cups has received a lot of likes. Friends who like it can read the articles we have published.

First of all, let’s look at the hardness of the paint, from weak to strong, it includes ordinary paint, hand paint, metal paint, high temperature resistant paint, plastic powder, and ceramic paint. Hard paint means that the paint has strong abrasion resistance. Ordinary paint has poor hardness. Some paints do not perform well. After ordinary paint is sprayed and processed, you can use sharper nails to draw marks on it. Most paints have a matte effect, but the hardness is relatively low and scratches are easy to occur. The paint is on the bottom of the water cup. After a period of use, due to frequent contact and friction between the bottom of the water cup and flat surfaces such as the table, the paint on the bottom will fall off. . The hardness of metallic paint and high-temperature resistant paint are similar. Although the hardness is better than ordinary paint, its wear resistance is also average. If you scratch it with some hard and sharp objects, obvious scratches will still appear.

The hardness of plastic powder is not as good as that of ceramic paint. However, as long as the water cup processed by spraying plastic powder is not scratched with a sharp object similar to metal hardness, the scratches on the surface of the plastic powder will not be obvious. Many of them will not be noticed unless you look carefully. Discover. This is not only related to the hardness of the plastic powder, but also has a lot to do with the processing method of the plastic powder.

Ceramic paint is currently the hardest of all stainless steel water cup surface spray paints, and it is also the most difficult to produce and process. Due to the high hardness and smooth material of ceramic paint, the adhesion of the ceramic paint is poor, so you must be sure before spraying ceramic paint. It is necessary to sandblast the location where the stainless steel water cup needs to be sprayed to give the sprayed location a frosted effect and add more bonding surfaces, thereby increasing the adhesion of the ceramic paint.

A stainless steel water bottle sprayed with high-quality ceramic paint will hardly leave any traces on the coating surface even if you use a key to swipe it vigorously. Although ceramic paint spraying has the best performance, due to issues such as material cost, processing difficulty, and yield rate, the proportion of water cups sprayed with ceramic paint on the market is still relatively small.
