摘要: A chafe or fire sleeve for a hose is an integral coaxial structure having an inner layer of silicone and an outer layer of urethane in the range of 80%-20% urethane and 20%-80% silicone, respectively. The inner hose structure preferably comprises an elastomeric hose covered by braid, with the silicone bonded onto the braid. Five examples of materials are given, ranging from pure urethane to pure silicone and including three exemplary mixtures thereof. Pure urethane provides excellent antichafe, but not fire retardant, qualities; and pure silicone provides excellent fire retardant, but not necessarily as good antichafe, qualities. This particular invention is primarily directed to the fire retardant or fire resisting qualities of silicone, which is an ablative material that forms a refractory ash. The fire sleeve is an ablative material which tends to flake off the hose as it burns. This flaking is a disintegration of the hose which is one of the primary causes of the ultimate hose failure. The invention provides a wire braid which encapsulates or contains the ablative material as it tends to flake, thereby holding the ablating material against the hose and retarding the disintegration of the hose.
摘要翻译: 用于软管的洁具或防火套管是一体的同轴结构,其分别具有80%-20%氨基甲酸乙酯和20%-80%硅氧烷范围内的硅氧烷内层和外层聚氨酯。 内软管结构优选地包括由编织物覆盖的弹性软管,其中硅胶结合到编织物上。 给出了五种材料的实例,范围从纯聚氨酯到纯硅酮,包括三种示例性的混合物。 纯氨基甲酸酯提供优异的反安全性,但不具有阻燃,品质; 纯硅胶提供优异的阻燃性,但并不一定具有良好的抗交感,品质。 这个特别的发明主要是针对形成耐火灰的可消除材料的硅树脂的阻燃性或耐火性。 防火套是一种烧伤材料,在燃烧时易于剥离软管。 这种剥离是软管的分解,这是最终软管故障的主要原因之一。 本发明提供了一种线编织物,其在易于剥落的情况下封装或包含可烧蚀材料,从而将烧蚀材料保持在软管上并延缓软管的分解。
