The main component of a quartz crucible is silicon dioxide, which has good stability and its performance is closely related to the molding process. This article introduces the injection molding process of this type of timely product.
1. The molding of quartz crucible slurry is an early molding method. Due to the use of gypsum molds, the cost is low and it is easy to form large and complex parts. The preparation of slurry is the key to injection molding.
2. Add a debonding agent and a binder with water as a flux, grind thoroughly, and then exhaust and pour into the gypsum mold.
3. The slurry absorbed by the capillary tube of gypsum mold can be solidified in the mold.
For the grouting of quartz crucibles, when the slurry absorbed by the mold wall reaches the required thickness, excess slurry needs to be poured out.
5. Reduce body shrinkage and use high concentration slurry as much as possible.
6. According to different requirements, organic additives are added to the ceramic slurry to form a double layer on the surface of the particles in the slurry, so that the slurry can be stably suspended without precipitation.
The above is a brief introduction to quartz crucible grouting technology. I hope you can have a more accurate and in-depth understanding of the product, which will be helpful for future use. However, it should be noted that it is a fragile item, so it should be handled with care.
