Can you clearly identify the ” laser ID card “of the surgical mask?
The epidemic caused by the new #Coronavirus/#COVID-19 raged across the world, and the demand for #surgical masks. In the current epidemic, a small mask affects all industries.
At present,in China many energy and manufacturing companies of Foxconn, BYD, SAIC-GM-Wuling, Sinopec, and GAC have joined the army of conversion masks; data show that from January 1 to February 7, 2020, there are more than 3000 The business scope of the company has newly added “masks, protective clothing, disinfectant, thermometer, medical equipment” and other businesses, and actively fights against the “epidemic”.
Some people are fighting against the “epidemic” in the past, while others are taking the money. The huge demand gap has also caused some illegal traders to take advantage of it, and a large number of inferior masks have flowed into the market. Terms related to “fake masks” and “mask fraud” have repeatedly appeared on hot searches.
Therefore, how to solve the problem of mask recognition and anti-counterfeiting has become the top priority, such as the 3M N95 / KN95 series masks that were robbed by high prices in the early stage: boxed 3M masks can be identified by the anti-counterfeiting label on the mask packaging box.
The label of the real mask will change color from different perspectives, while the label of the false mask will not change color
For bulk 3M masks, you can distinguish the authenticity by observing the font on the mask.The real 3M mask text is marked by laser, and the font has twill,
The fakes are printed with ink, with dots or other uneven marks.
In fact, not only in the identification of masks, laser marking has always been closely related to the pharmaceutical industry, and it has been widely used in precision medical equipment, medical packaging, pills, soft capsules and other areas with special needs.
Compared with the traditional ink printing technology, laser marking has the characteristics of non-toxicity, pollution-free, high efficiency, high definition, high precision and wear resistance, which has fundamentally solved a series of problems in traditional ink printing technically It can be said that laser marking technology has been escorting the medical industry since its birth.
As we all know, there are many types of lasers marking machine, and the applicable materials are also different. For example, fiber laser marking machine is suitable for various metal materials, CO2 laser marking machine is suitable for most polymer materials, and ultraviolet laser marking machine/uv laser marking machine is suitable for more precise and demanding application scenarios.
At present, most of the laser marking machines on the market used for marking the surface of face masks.
When UV laser marking machine is applied to high molecular polymers such as PI, it can directly break the chemical bond of the material, so that the material fragments are discharged in the form of small particles or gas, so as to achieve the purpose of stripping and removing the material.
Since most of the energy is used to break chemical bonds, very little energy is converted into heat energy, thereby basically eliminating the changes in the heat affected zone and surrounding materials.
For most white plastics (the pigment is TiO2), TiO2 will strongly absorb ultraviolet rays and change the crystal structure. This change makes the material in the corresponding area appear dark, resulting in a smooth, legible mark inside the material.
The laser dual-station UV laser marking machine is suitable for marking and micro-hole processing on the surface of glass, polymer materials and other objects. It is widely used for marking and perforating the surface of packaging bottles (boxes) of polymer materials such as food, medicine, cosmetics, electric wires, etc. (Aperture d <10 um).
