What is the operation method of Shanghai silicone replica?
Today, we follow Shanghai Lingying Model Co., Ltd. to understand the operation method of Shanghai silicone replica?
1. Stir silica gel and curing agent evenly: the appearance of mold silica gel is flowing liquid, component A is silica gel, and component B is curing agent. For example, take 00g of silica gel and add 2g of curing agent (Note: silica gel and curing agent must be stirred evenly. If they are not stirred evenly, one piece of the mold will have been cured, and one piece will not be cured. The silica gel will have uneven drying and curing, which will affect the service life and mold turnover times of the silica gel mold, and even cause the mold to be scrapped.
2. Vacuum exhaust bubble treatment: After the silica gel and the curing agent are stirred evenly, the vacuum exhaust bubble process should be carried out. The vacuum time should not be too long. Normally, it should not exceed ten minutes. If the vacuum time is too long, the silica gel will be cured immediately, resulting in cross-linking reaction. The silica gel will become pieces, and can not be painted or poured. This wastes the silica gel. The silica gel can only be poured into the trash can, and then the silica gel can be taken again.
3. Brushing or operation process: The silica gel that has been evacuated and drained of bubbles is brushed or poured. Pour it over the product. Then apply the silicone on the product. The coating must be even. After 30 minutes, paste a layer of gauze and weft cloth to increase the strength and tension of the silicone. Then apply a layer of silica gel, and paste a layer of gauze and weft cloth, so that it can be done after two times.
