耐火材料试件制备 用气动喷嘴混合式喷枪喷涂耐火板

[中文适用范围]： 本文件描述了在环境温度下通过气动喷嘴混合枪喷射耐火材料制备测试面板的程序。测试件用于确定在“标准条件”（质量保证或产品开发所需）或“现场条件”下制备的喷射产品的性能。在“现场条件”的情况下，测试的目的是确定与给定安装或给定安装条件集相关的性能。在这种情况下，面板可以在现场安装期间获得。面板制备过程中适用的环境温度、喷射高度、气压和固化条件（温度、面板方向）等参数尽可能接近与现场安装相关的相应参数。也可以通过在场外（例如在实验室环境中）喷射面板来模拟某些“现场条件”。根据相关方的协议，这在本文件中是可接受的。本文件不适用于塑料喷射混合物和含有易受水合作用的骨料的混合物。本文件不适用于喷射混凝土型混合物，该类混合物已在 ISO 18886 中处理。 [外文原描述]： This document describes the procedure for the preparation of test panels from refractory materials by gunning through pneumatic nozzle mixing type guns at ambient temperatures. The test pieces are for the determination of properties on as-gunned products prepared under either “standard conditions” (as required for quality assurance or product development) or “site conditions”. In the case of “site conditions”, the purpose of the testing is to establish the properties pertaining to a given installation or a given set of installation conditions. In this case, the panel can be obtained during the on-site installation. Parameters such as ambient temperature, gunning elevation, air pressure and curing conditions (temperature, orientation of the panel) applicable during the preparation of the panel are as near as possible to the respective parameters pertaining to the site installation. It is also possible to simulate certain “site conditions” by gunning panels off-site, for example, in a laboratory setting. This is acceptable under this document, by agreement between interested parties. This document does not apply to plastic gunning mixes and to those mixes that contain aggregates that are susceptible to hydration. This document does not apply to shotcrete type mixes, which are dealt with in ISO 18886.
