Full screen blast market laser technology glass applications to a new journey

  Millet mix2 full-screen mobile phone officially detonated a full screen glass era, the major international brand handset manufacturers get together release. Full screen with its better visual effects, more beautiful appearance and the advantages of unshielded signals are widely recognized by the market. From here, we can understand the application of glass materials in the 3c is also increasingly important.

  Our commonly used glass products are daily cup, bowl of these, in fact, glass products have been widely used in construction, medical, chemical, home, electronics, instrumentation, nuclear engineering and other fields. Glass has the characteristics of fragile, so the glass surface sculpture, the process demanding.

  Common glass processing techniques are as follows:
  Etching method
  Use chemicals - hydrofluoric acid to corrode the glass. First melted with paraffin and cover the glass, carved in the surface of the wax pattern, and then coated with hydrofluoric acid can be washed to paraffin. Since hydrofluoric acid is volatile and polluted seriously, it needs protective layer and its operation is complicated.

  Thermal processing
  Thermal processing is used to improve the appearance of the quality of processed materials, there are flame cutting, fire polishing, drilling and so on. However, glass brittle high, easily affected by the cracking of high temperature damage to the material.

  screen printing
  Screen printing principle is to print the ink to the surface of flat glass, and then use the ink curing measures to make the pattern firm. However, screen printing process complicated, harmful to human body ink, and silk screen is not good color, less color, poor coloring.

  Laser Marking
  Laser marking is a photo-electric machine integrated device controlled by a software system. Produced by software control graphics, the use of non-contact processing, so that the glass will not be damaged by external forces, perfect glass and fine processing effect.

  From the processing technology can be seen laser marking is better than other processing technology, but the use of laser marking on the glass there are several processes, the process is as follows:
Multiple laser radiation method
  Using a laser radiation to produce a marked outline on the glass surface, the laser extends a few days to the area outside the original mark to form fragments and then uses multiple irradiations to heat the areas adjacent to the marked area by heat conduction to form these areas Stress gradient, thereby reducing the possibility of secondary rupture, using this method in soda lime glass and borosilicate glass marking is very effective. Containers filled with liquid pharmaceutical small glass, glass in life can use this method of marking.
  Discrete points form a ring-shaped crack
  Use a series of ring-shaped cracks to form text, bar codes, square or rectangular codes, and other shape code patterns. The common use of this method CO2 laser marking machine more, CO2 laser marking machine set a glass marking code generated by the crack is relatively small. Discrete points appear ring-shaped cracks. Glass heats and cools to produce low-density annular cracks. When heated, the glass expands and compresses the surrounding material. As the temperature rises to the softening point of the glass, the glass expands rapidly to form a dome of the convex glass surface of a low-density material. The use of CO2 laser marking machine, businesses can be beautifully marked in the glass surface pattern, commissioned glass grades.
  Produce crack-like surface crack method
  The use of heating and cooling to change the surface of the glass to which it is applied can not be seen immediately. It begins with a slight amount of pressure and then begins to produce turtle-shaped cracks along the laser marking area. Cracked glass surface not only has the safety of glass, but also play a non-full effect of ice cracking, it is widely used in interior decoration, such as partitions, walls, can also be used for glass furniture, loved by consumers.
