The production process of liquid silica gel products in Yingtai Factory is as follows:
1. Material preparation: liquid silica gel: select a suitable model (such as lsr). Curing agent: mixed in proportion. Color paste: used for coloring (optional).
2. Mold preparation: mold design: mold design according to product requirements. Mold cleaning: ensure that the mold is free of dust and oil. Release agent coating: easy to release.
3. Mixing liquid silica gel: mixing liquid silica gel and curing agent in proportion and stirring evenly. Add color paste (if necessary) and continue stirring.
4. Vacuum degassing: put the mixed liquid into a vacuum pump to remove bubbles.
5. Injection molding: injection molding: injecting silica gel into the mold by using a liquid silica gel injection machine. Manual pouring: manual pouring can be used in small batch production.
6. Curing: heating curing: heating the mold to 120 C-180 C to accelerate curing. Room temperature curing: part of silica gel can be cured at room temperature for a long time.
7. demoulding: take out the product carefully after curing to avoid damage.
8. Post-treatment: trimming: removing burrs and redundant parts. Cleaning: clean the surface of the product. Secondary curing: some products need secondary curing to improve performance.
9. Quality inspection: dimensional inspection: to ensure that it meets the design requirements. Performance test: such as heat resistance, chemical resistance, etc.
10. Packaging and storage: Store after packaging to avoid pollution and damage.
Note: accurate proportion: ensure the correct proportion of silica gel and curing agent. Avoid bubbles: The degassing step is very important. Environmental control: temperature and humidity affect the curing effect.
