Introduction of cultural stone mold silica gel:
The mold silica gel used to remould the cultured stone generally has a slightly higher hardness, 30-40 degrees Celsius is appropriate, and both condensed silica gel and addition molded silica gel are suitable. The cost of condensed silica gel is a bit cheaper, and the added molded silica gel is food-grade silica gel, which is environmentally friendly, non-toxic and odorless, so the price will be slightly more expensive, and you can get what you need. Cultural stone mold silica gel is also a kind of ordinary liquid silica gel. It has two components, component A is silica gel, and component B is curing agent. Mixing the two in a certain ratio can be cured and molded. The higher hardness of the silica gel, the higher the hardness of the silica gel mold, it is not easy to be crushed and deformed by the weight of the cement during the process of turning the cement, and the tear resistance is better. Moreover, the silicone mold has a certain degree of flexibility, therefore, the mold silicone is the best mold material for cement product turnover.
Application areas of cultural stone mold silica gel:
It is especially suitable for the reproduction of large-scale stone, plaster, cement, cultural stone, artificial stone, Roman column, stone carving and other furniture, architectural decoration and decoration products; it can also be used for simulation of animal and plant sculptures, resin crafts, plaster craft gifts, poly Reproduction of craft ornaments in various industries, such as handicrafts, Buddhist sculptures, and other industries, and production of silicone molds.
Performance characteristics of cultural stone mold silica gel:
1. High-strength anti-tear performance, no deformation, very suitable for turning molds of cultured stone.
2. Good elasticity, easy to demold, and will not damage the product during demolding.
3. Convenient adjustment of fluidity: low viscosity when filling the mold, good fluidity, easy to drain; when brushing the mold, the viscosity can be adjusted higher, which is convenient for brushing the mold.
4. High and low temperature resistance, acid and alkali resistance, aging resistance, non-expansion, which is good for repeated use of the mold.
5. The shrinkage rate is much smaller than that on the market, and the shrinkage resistance is better after adding the glass fiber cloth.
