For applications in high temperature environments, a high temperature resistant gel foam formulation with a novel semi-interpenetrating network structure was created. It was specifically determined experimentally what affects component concentration and temperature had on gelation time, gelation strength, and foam qualities by the use of a single-factor screening research and response surface analysis (RSA). The findings revealed that the foam volume grew from 370 ml to 390 ml before and after aging at 100 °C, the precipitation half-life was increased from 25 min to 50.4 min. The foam stabilization period was doubled by the optimized temperature-resistant gel foam, which also greatly improved temperature resistance. The gel foam performed best when the coordination ratios of NaOH, AA, AMPS, MBA, APS, sodium streptavidin sulfonate (AOS), alkyl glycoside (APG0810), alkyl amide betaine (FM-20AB), and silicone resin polyether emulsion (MPS) were 1.4 %, 5 %, 2.4 %, 0.7 %, 0.1 %, 1.6 %, and 0.2 %, respectively. The SEM examination and thermal weight loss investigation showed that the enhanced gel foam generated an enhanced mechanism with greater temperature resistance and stability and considerable potential application areas.

耐温凝胶泡沫制造和性能评估的响应面分析 (RSA) 优化

针对在高温环境中的应用,创建了一种具有新型半互穿网络结构的耐高温凝胶泡沫配方。通过使用单因素筛选研究和响应面分析 (RSA),通过实验具体确定了影响组分浓度和温度对胶凝时间、胶凝强度和泡沫质量的影响。结果表明,在 100 ℃老化前后,泡沫体积从 370 ml 增长到 390 ml,沉淀半衰期从 25 min 增加到 50.4 min。经优化的耐温凝胶泡沫使稳泡期翻倍,耐温性能也大大提高。当 NaOH、AA、AMPS、MBA、APS、链霉亲和素磺酸钠 (AOS)、烷基糖苷 (APG0810)、烷基酰胺甜菜碱 (FM-20AB) 和有机硅树脂聚醚乳液 (MPS) 分别为 1.4%、5%、2.4%、0.7%、0.1%、1.6% 和 0.2%。SEM检查和热失重研究表明,增强型凝胶泡沫产生了一种增强的机制,具有更高的耐温性和稳定性,具有相当大的潜在应用领域。
