The process flow is as follows: 1. First, put the printed-washed objects flat on the console with the same level and wait for drip. 2, according to the dosage, take a cup, accurately weigh out glue A (for example, 9g), then weigh out glue A and glue B (3g), and mix them evenly according to the ratio of 3: 1 (some crystal glue ingredients according to the ratio of 2:1, and there is also a ratio of 1: 1. ) 3. Take a clean syringe, suck the prepared glue into the syringe and drip it evenly on the surface of signs, trademarks, etc. Generally, the thickness of crystal glue layer is 2mm, so that it can be naturally leveled. 4. 3-5 minutes after crystal glue is instilled, observe whether there are bubbles or dust particles on the rubber surface. If there are small bubbles, you can use a small needle to pick them off. If you find that the dead corner is not leveled with crystal glue, you can extradite them with a needle. 5. The poured signboard will be cured at room temperature of 2℃-22℃ for 1-14 hours and hardened to become a crystal signboard with non-stick surface. 6. In case of adhesive, trademark, etc., its thickness is very thin, and the boundary is not obvious. When pouring, it is easy to cause crystal glue overflow, and it is difficult to reach the thickness of 2mm. Therefore, it is necessary to control the viscosity according to different situations in making crystal glue, and it can be placed for 1-2 hours in the application process to improve the viscosity and adapt to the pouring of thin crystal glue. 7. Make crystal glue signs with a thickness greater than 2mm, which can be dripped twice. After the first drip, it will be cured for 3-5 hours, and then a layer will be dripped. 8. Cleaning after plastic dropping (using toluene, xylene, cyclohexanone) containers need to be cleaned. If the glue is insoluble in any solvent after hardening, it must be cleaned in the machine and containers before it hardens.
