Misunderstandings about surface spraying when buying stainless steel water cups

Today, I will continue to share what misunderstandings there are when buying stainless steel water cups. http://www.umbottle.com/ProductsDetail-VB-10110.htmlWhen buying stainless steel water cups, some people like the original color of stainless steel, and many friends like the water cups with color sprayed on the surface. Choose your favorite color and you will have a good mood when using it.

At present, the surface coloring processes of stainless steel water cups on the market are basically these:

spray painting, spray powder, vacuum plating, printing, printing, etc. http://www.umbottle.com/ProductsDetail-VB-10110.htmlPrecisely because there are many surface coloring processes for water cups, and there are many types of coloring materials used, some bad manufacturers will use non-food grade coatings and production processes to achieve a more beautiful effect, make the color more adherent and reduce costs. Next, I will share with you in detail.

Thinking that the spray coating must be environmentally friendly: Some consumers may mistakenly believe that the coating layer sprayed on the surface of a stainless steel thermos cup must be environmentally friendly, but in fact, not all spray materials are environmentally friendly. http://www.umbottle.com/ProductsDetail-VB-10110.htmlMany environmentally friendly food-grade materials have insufficient adhesion due to various production index restrictions, but some uncertified spray materials have strong adhesion and strong wear resistance after baking, but contain harmful substances, such as heavy metals or volatile organic compounds, especially some water cups completely cover the mouth of the cup when spraying the coating.

As the editor shared earlier, the rising heat will cause the temperature of the cup mouth to be higher. At high temperatures, these non-food-grade coatings will release harmful substances. http://www.umbottle.com/ProductsDetail-VB-10110.htmlWhen people drink water, they will absorb the harmful substances together, so it poses a potential threat to health. Therefore, when consumers choose stainless steel thermos cups, they should pay attention to the environmental performance of the spray material, and try to choose certified environmentally friendly spray materials. The simple way to identify is to smell it to see if there is any smell. Food-grade spray materials have no smell after processing.

Ignore the wear resistance and durability of the spray coating: This is not inconsistent with the previous one. Ignore because everyone likes different gloss effects of spraying. http://www.umbottle.com/ProductsDetail-VB-10110.htmlSome friends like glossy ones, while others like matte ones. Usually the color of glossy ones is more vivid, and more spraying is used. In the previous article, the editor said that since the materials need to reach food grade, there are strict requirements on the material composition and various indicators, which results in poor adhesion of food-grade coatings.

Here we are mainly talking about paint. Both glossy paint and matte paint are easy to fall off after a period of use. Matte paint will have a sticky feel on the surface after a long time of use.http://www.umbottle.com/ProductsDetail-VB-10110.html Stainless steel water cups using powder spraying technology are more wear-resistant, but they are mainly matte, and the colors are relatively not so bright. In particular, plastic powder paint that can pass the dishwasher test will have stronger wear resistance after spraying.

Mistakenly believe that the spray coating can completely isolate the external environment: The material sprayed on the surface of the stainless steel water cup cannot enhance the heat preservation function, nor can it enhance the resistance of the stainless steel water cup to falling. http://www.umbottle.com/ProductsDetail-VB-10110.htmlThe material sprayed on the surface of the stainless steel water cup is for the beauty of the water cup, and also prolongs the service life of the water cup through its own wear resistance. However, these coatings will also be corroded, and some potions, chemicals and strong acidic liquids may corrode them.

By understanding and avoiding these misunderstandings in spraying materials and spraying processes, http://www.umbottle.com/ProductsDetail-VB-10110.htmlconsumers can more scientifically choose the stainless steel thermos cup that suits them, avoiding affecting their shopping experience and product usage effects.
