新型防灭火封堵材料--固体泡沫特性参数实验研究-experimental study on characteristic parameters of solid foam, a new type of fire-fighting and blocking material.docxVIP

摘要煤矿火灾是影响矿井安全生产的重大灾害之一，快速封堵矿井漏风通道是防止 自然发火的有效措施，火 区 封闭也是煤矿灭火的常用方法。煤矿越来越多地采 用泡沫灭火对矿井进行防灭火处理， 如何快速严密地封堵漏风通道及封闭火区是 目前亟待解决的问题。本文介绍了新型防灭火封堵材料—固体泡沫的特点、参数、 优缺点以及适用条件。通过对新型固体泡沫的发泡倍数和抗压强度等特性进行实验 研究，测出了不同配比时的发泡倍数和抗压强度，找到了泡沫的最大发泡倍数和最 大抗压强度值，并利用 Origin7.0 绘制发泡倍数与抗压强度之间的曲线图，得出两 者之间存在的线性关系。为泡沫进行添加无机物和泡沫的气密性等其他特性试验研 究提供参考数据，为煤矿井下漏风通道的快速封堵或火区巷道的快速封堵技术提供 理论依据。关键词：固体泡沫；防灭火；发泡倍数 ；抗压强度；发泡剂AbstractMine fire is one of the major disasters that affecting in production safety，It’s effective measure to prevent spontaneous combustion that rapidly closure of air leakage channel in mine. closed fire district is also a commonly used method in mine fire. More and more applying of the foam extinguishing agent for the fire prevention and treatmentis used in mine. At present，it’s to be resolved problem that how to block the air leakagechannel and the closed fire zone rapidly and tightly.is article introduced the feature， the parameter，the merit and drawback and the apply condition of this new kind of solid foam， measured the expansion rate of foam and compression strength in different proportion ， and found the maximum value of the expansion rate of foam andcompression strength. It drew the graph of the expansion rate of foam and compression strength by the origin7.0 and reached the linear relation of each other. This article researched the character of the foam multiple and compression strength of this new kind of fire prevention and block material—solid foam. It afford the reference data for the experimental research of adding inorganic in foam and gas tightness of foam. And it afford the theory evidence for rapidly closure of air leakage channel in mine and closed fire district.Key Words： solid foam; fire prevention; expansion rate of foam; compression strength; foaming agent目录摘要Abstract1 绪论 .............................................................................................................. 11.1 论文选题的背景 ...............................................................
