    • A container protective against high temperature of restricted duration is formed of a mixture of plaster of paris containing incombustible reinforcing filler, such as glass fibres, and/or insulating filler, such as glass spheres; and a particulate inorganic hydrate, such as magnesium sulphate, which may have a water-insoluble coating. It may also contain an infrared opacifier, such as chromium oxide. The container cover is preferably stepped, to eliminate a direct radiation path between the cover and the container; and the stepped seat or the stepped edge of the cover may be covered with a fusible incombustible material, such as a glass cloth of suitable melting point, to seal the joint between cover and container in the existence of high temperature. The wall structure may be graded, having higher melting filler and reinforcement at the exposed face, and lower melting filler at the interior portions.
    • 防止高温限制的容器由含有不燃性增强填料如玻璃纤维和/或绝缘填料如玻璃球的混合物形成, 以及可能具有水不溶性涂层的颗粒状无机水合物,例如硫酸镁。 它还可以含有红外线曝光剂,例如氧化铬。 容器盖优选是阶梯式的,以消除盖和容器之间的直接辐射路径; 并且盖子的台阶座或台阶边缘可以用可熔的不燃性材料(例如适当熔点的玻璃布)覆盖,以在存在高温的情况下密封盖和容器之间的接合部。 壁结构可以分级,在暴露的表面具有较高的熔化填料和增强物,以及在内部部分具有较低的熔化填料。

    • Copending disclosure teaches the addition of particulate hydrated inorganic compound, such as hydrated magnesium sulphate, to plaster of paris formulation so that, when plaster has set, particles of hydrate will be dispersed in solid plaster. Such plaster will survive high ambient temperatures longer than conventional plaster without hydrate inclusions, because ablation of water of hydration will carry away entering heat. This patent discloses coating the particles of water-soluble hydrate with a water-insoluble protecting layer, such as paraffin wax, prior to their inclusion in the plaster formulation, to prevent any solution of the hydrate in the water used in preparing plaster mix.
    • 一般的公开内容教导了将石灰水合无机化合物如水合硫酸镁添加到石膏制剂中,使得当石膏固化时,水合物颗粒将分散在固体石膏中。 这样的石膏将比常规的石膏更长的环境温度下生存,没有水合物夹杂物,因为水合水的消融会带走热量。 该专利公开了在石膏制剂包含之前用水不溶性保护层(例如石蜡)涂覆水溶性水合物颗粒,以防止在用于制备石膏混合物的水中使用水合物的任何溶液。
