摘要： A cost-effective starch/water-based binder composition and related method for forming silica sand cores and molds for foundries, wherein the sand grains are pre-coated with starch having additives making the coated sand effective for blowing said cores and molds. One or more additives are included with the starch; preferably sodium tripolyphosphate and silicon or Silres BS16. The preferred starch is a tapioca starch. The binder of the invention is highly competitive due to its low cost and effectiveness for forming silica-sand cores and molds, being particularly effective for use in aluminum foundries for the automotive industry.

摘要： A water-dispersible casting mould, particularly a core, for the manufacture of castings is proposed. The mould contains a water-insoluble, particulate material, such as moulding sand, a binder, which has a first binder component based on a condensed phosphate, and optionally a flux. In order to ensure an increased flexural strength and abrasion resistance, there is a second binder component based on polyamines. It is also possible to provide a flux based on alkali metal carbonate, which gives the mould an increased thermal stability. The invention also relates to a method for the manufacture of such a mould, in that the aforementioned components are mixed, accompanied by the addition of water, the mixture is moulded and at least part of the added free water is removed.
摘要翻译：提出了用于制造铸件的水分散铸造模具，特别是核心。模具包含水不溶性颗粒材料，例如型砂，粘合剂，其具有基于缩合磷酸盐的第一粘合剂组分和任选的助熔剂。为了确保增加的抗弯强度和耐磨性，存在基于多胺的第二粘合剂组分。还可以提供一种基于碱金属碳酸盐的助熔剂，这使得模具具有更高的热稳定性。本发明还涉及一种用于制造这种模具的方法，其中将上述组分混合，同时加入水，混合物被模塑，并且除去至少部分添加的游离水。

摘要： An improved phosphate-type refractory investment material and method for marking solid investment molds especially useful for casting high melting point metals and alloys, such as platinum and the like. The material consists essentially of one or more phosphate salts, one or more water soluble organic acids, and refractory powder. The material can be prepared as a dry powder blend which is easily shipped to the user and mixed with water at the time of investing the flask. Alternatively, the salt and/or organic acid can be combined with the refractory powder at the time of mixing with water.

摘要： A method for making foundry moulds and cores, according to which a self-hardening in the air plastic or liquid mixture is employed. Most advantageously the present invention may be used in making large-size foundry moulds and cores. The proposed method tends to increase substantially the thermal stability of both the moulds and cores due to the effect which the properties of the materials, utilized as a binder, exert on the sand. In addition, the hardening rate of the mixture is increased which is coupled with the simplified knocking-out of the sand from castings.
