Mobile phone cases are standard equipment for everyone who owns a smartphone, not only China, but also have very large sales in mobile phone case printing worldwide. However, the recent release of a black list of mobile phone cases has made people start to panic The mobile phone case we hold every day actually contains toxic substances. Why are these mobile phone cases harmful to people’s bodies made of poison?
UV tablet can be used for mobile phone case printing. At present, many domestic mobile phone case processing manufacturers use mobile phone case processing, mainly in South China, with good market conditions and high profits. However, there are also some small workshops for basic mobile phone case processing. The ink usage and ink detection of these printers have not undergone professional procedures. Therefore, many mobile phone cases with substandard quality have appeared on the market. These failed mobile phone cases attacked.
Of course, the phone case exposed in the black list of phone cases we are talking about here does not cover the material of the phone case, but only the printing process and the application of ink, so do not confuse the material with the process.
So what is the difference between high-end printing processes and inks and low-end ones?
This needs to explain the principle of printing.
When a printer prints a mobile phone case, it usually puts a layer of white ink on it. After printing the white ink, it prints color ink on the phone case. Some high-end phone cases also print a layer of varnish on the color ink.
People usually touch the phone case, there will be some relief texture, these are the effects of white ink piled up underneath, people usually see the phone case shiny and reflective effects, these are also the effect of varnish.
One of the fatal flaws of white ink is its heavy smell. But this smell can be covered with color ink. In some devices, the coverage of the printed color ink is not precise, and white ink is not covered, so some odors are generated.
Therefore, in the black list of mobile phone cases, there will be a special description of the problem of pungent odor. These pungent odors, in addition to the material itself, also come from white ink.
Again, we are not discussing the material itself, but discussing the printing process of the phone case.
Another problem is that harmful substances exceed standards. In the process of UV printing, there are indeed some equipment used inks containing harmful substances. But more are environmentally friendly UV inks. Take PS Torui as an example. The UV inks required for printing have been professionally tested and do not contain harmful volatile gases (VOC). At the same time, the UV ink is cured with high power during the curing process. No harm to human body. Of course, you should avoid eating anything, and don’t let children get teeth. This needs everyone’s attention.
According to the news report: The more beautiful the phone case, the more toxic it is.
This sentence is not accurate. The more beautiful the phone case, the higher the printing process and quality, which is not directly related to the toxicity study. How can such a conclusion be reached? Of course, we guess that the author may want to express that the beautiful mobile phone case uses a lot of materials such as gold and silver powder, which affects the environmental protection of the phone case. But in fact, gold powder and silver powder can not make the phone case beautiful, but only make the phone case more and more tacky.
Today, the mobile phone case industry has high profits and strong demand. Many people in the early days of entrepreneurship hope to have a good printer for high-quality mobile phone case printing.
