    • In a method of making a molded article for use in a casting process, sand particles are mixed with protein and water to effect a coating of protein on the sand particles. Then, the protein coated sand particles are dried and blown into a pattern mold to form a molded article without active cooling of the coated sand particles. Steam is then passed through the molded article to hydrate and melt the protein, thereby forming bonds between contiguous sand particles. Finally, hot, dry air is passed through the molded article to harden the protein bonds between the contiguous sand particles. This forms a protein coated sand core for use in casting molten metals.
    • 在制造用于铸造工艺的模塑制品的方法中,将砂粒与蛋白质和水混合以在砂粒上进行蛋白质包衣。 然后,将蛋白质包覆的砂粒干燥并吹入图案模具中以形成模制品,而不主动冷却涂覆的砂粒。 然后将蒸汽通过模制品以使蛋白质水合并熔化,从而在连续的砂粒之间形成粘结。 最后,将热的干燥空气通过模制品以硬化连续砂粒之间的蛋白质键。 这形成了用于铸造熔融金属的蛋白质包被的砂芯。

    • An animal collagen or gelatin based crumble, and processes for the preparation of the particulate crumble, are useful in the preparation of collagen or gelatin based compositions. The crumble is prepared by extracting animal collagen from an animal tissue source and combining the collagen with sufficient water to form a composition comprising about 15-45 wt % animal collagen and about 0.01-5 wt % of a stabilizer or preservative. Such a combination of materials can be solidified and then processed into a large particulate format. The large particulate comprises a, regular or amorphous shaped, roughly crumbled or roughly divided, crumble product. The typical particle size of a majority of the crumble is about 0.2-5 cm. The crumble is easily manufactured, packaged, stored, handled and distributed. The crumble can be easily used as is. The material melts easily into a use locus. The crumble is also particularly adapted to a use in combination with an aqueous diluent to form an aqueous animal collagen or gelatin solution that have a variety of uses. The aqueous solution of the crumble can be made with minimal heating to dissolve the crumble in the aqueous liquid.
    • 基于胶原蛋白或明胶的粉碎物以及用于制备颗粒粉碎的方法可用于制备基于胶原或明胶的组合物。 通过从动物组织来源提取动物胶原蛋白并将胶原蛋白与足够的水组合以形成包含约15-45重量%的动物胶原和约0.01-5重量%的稳定剂或防腐剂的组合物来制备粉碎物。 这种材料的组合可以固化,然后加工成大颗粒形式。 大颗粒包括一种规则的或无定型的,大致粉碎的或大致分开的粉碎产品。 大部分破碎物的典型粒径约为0.2-5厘米。 崩溃易于制造,包装,储存,处理和分发。 崩溃也可以轻松使用。 材料易于熔化成使用场所。 粉碎也特别适用于与水性稀释剂组合使用以形成具有各种用途的水性动物胶原或明胶溶液。 粉碎的水溶液可以以最小的加热进行,以溶解在水性液体中的碎屑。
