As for the bliste​β§ ring phenomenon in la€←↕<ser marking of some plπ←αastic materials, the ε→main source is the workpi♦'★₽ece itself. Now, please follow Foshan F εulan Laser to see what theδ♦γ reasons are:
1. The marking shall be carried ou♥₽t after the treatment↕€∑​ of protective oil (i.e. seali σ©ng oil). Bubbling is unavoidable.
2. When the bottom paint film is not co✔♠‍mpletely dry, the surface paint sσ§hall be coated again.
3. The joints and eye¥≈£÷lets of the substrate♣♥ are not filled, and ther≥£®e are gaps and eyelets.
4. Paint viscosity is too hig★×σh. Improper paint mix.
5. Drag the brush back and forth ≥‌®during brushing, and the bubbles ge'✔nerated are not elimina§πted.
6. There is water in the compressor and✘> air pipe, or water splashesΩ® on the construction surface.☆≤φ
7. If the substrate is not prope∏★rly treated, bubbles may occur wh↔™en the residual substances volatil'¥‍φize naturally.
