摘要: Slurries containing tri-or polyvalent cations are used for investment casting and making molds as well as core coatings. These slurries are aqueous or alcohol-based containing a mineral component and a polyanionic binder, where at least one of the continuous phase or mineral component contains trivalent or polyvalent cations or cations that are converted into trivalent or polyvalent cations during use. The cationic component is selected from a group consisting of at least one of the metals iron or aluminum. The polyanionic component contains at least one of the group consisting of colloidal silica or one or more water-soluble organic polymers.

摘要: A process for rapidly forming a ceramic shell mold on an expendable pattern is disclosed. The process entails use of refractory slurries which include a large particle size colloidal silica sol binder. The colloidal silica sol binder has an average particle size of about 40 nanometers, i.e., about 3-4 times larger than colloidal silica sol binders heretofore employed in manufacture of ceramic shell molds. The use of the large particle sols yields unfired ceramic shell molds which have about 40% to about 70% greater unfired strengths compared to ceramic shells made with prior art small particle size silica sols. Prime coats and refractory back-up coats which use the large particle size sol dry about 30% to about 40% faster than prime coats and back up coats which employ the smaller particle size silica sols of the prior art.
摘要翻译: 公开了一种用于在一次性模式上快速形成陶瓷壳模的方法。 该方法需要使用包括大粒径胶体二氧化硅溶胶粘合剂的耐火浆料。 胶体二氧化硅溶胶粘结剂的平均粒度约为40纳米,即在制造陶瓷壳模具中迄今为止使用的胶体二氧化硅溶胶粘结剂的约3-4倍。 与使用现有技术的小粒径硅溶胶制成的陶瓷壳相比,使用大颗粒溶胶产生未煅烧的陶瓷壳模,其具有约40%至约70%的未烧结强度。 使用大粒径溶胶的初级涂层和耐火后备涂层比使用现有技术的较小粒径二氧化硅溶胶的初涂层和背胶层快约30%至约40%干燥。

摘要: The invention relates to a water based binder for use in a slurry for investment casting. The binder includes a mixture of a colloidal silica sol and at least one latex polymer. The latex polymer is preferably an acrylic latex or a styrene butadiene polymer (or a combination of these) which reduces the processing time between dips during shell mold making for investment casting. The latex polymer further lowers a critical concentration point or gelation point of the colloidal silica sol. The binder may be used as a primary binder or a backup binder in the shell mold making process. To make the slurry, the binder is combined with at least one refractory powder, preferably a refractory powder selected from the group of: alumino-silicates, fused silica, quartz silica, alumina, zircon, and zirconia.
