摘要/Abstract

摘要： 燃气热水器燃烧室内的SUS430不锈钢隔热板存在高温变色问题。为此,首先进行了不锈钢变色模拟试验,采用CIELAB测色体系研究了SUS430不锈钢在高温氧化状态下的表面色度变化规律,表征了不同氧化状态表面氧化膜的物相构成及形貌,同时获得了不同氧化状态下不锈钢的耐蚀性数据。通过将不锈钢的耐蚀性与表面颜色变化状态进行关联,揭示了不锈钢在高温氧化状态的耐蚀机理。进一步改进风冷降温通道,优化了不锈钢隔热板结构,进而降低了燃烧室表面温度。经过六个月的风压堵塞耐久试验可知,优化后的隔热板可靠性提升,不再出现变色问题。

Abstract: The SUS430 stainless steel insulation plate in the combustion chamber of the gas water heater has a problem of color fading at high temperatures. To address this issue, firstly a simulation test on the color change of stainless steel was conducted. Using the CIELAB color measurement system, the surface chromaticity change law of SUS430 stainless steel under high-temperature oxidation was studied, and the phase composition and morphology of the surface oxide film in different oxidation states were characterized. Meanwhile, the corrosion resistance data of stainless steel under different oxidation states were obtained. By correlating the corrosion resistance of stainless steel with the surface color change state, the corrosion mechanism of stainless steel under high-temperature oxidation was revealed. Further improvements were made to the air-cooling cooling channel and the structure of the stainless steel insulation plate to reduce the surface temperature of the combustion chamber. After six months of wind pressure blockage durability tests, the reliability of the optimized insulation plate was enhanced, and the color fading problem no longer occurred.
