摘　　要：搪玻璃设备兼有金属强度和搪玻璃的耐高温、耐腐蚀、易清洁等优点,被广泛应用于医药、化工行业,成为当前化工行业不可替代的设备。但是,搪玻璃使用寿命短且其各项性能远达不到期望值,因此,通过引入添加物的方式提高搪玻璃理化性能对延长其使用寿命具有重要意义:通过提高搪玻璃网络结构的完整性,能够显著提高其化学稳定性;研磨添加剂以及硬质颗粒的添加降低了搪玻璃的孔隙率和摩擦系数,增强了抗磨损能力;界面处锚固点和枝晶体的增加能够显著增强搪玻璃的附着力;添加陶瓷颗粒能够降低热膨胀系数的差异,增强韧性以及阻氧能力,从而提高搪玻璃的高温防护性能。文章综述了添加物对搪玻璃耐腐蚀性、耐磨损性、密着性以及高温防护性能影响的研究,并进行了汇总分析,对后续开展试验研究具有一定参考价值。Enameled equipment has the advantages of metal strength and high-temperature resistance,corrosion resistance,and easy cleaning of enamel.It is widely used in the pharmaceutical and chemical industries and has become a piece of irreplaceable equipment in the current chemical industry.However,the short service life of enamel and its various properties are far from the expected value.Therefore,it is of great significance to improve the physicochemical properties of enamel and extend its service life by introducing additives.By improving the integrity of the network structure,the chemical stability of enamel is significantly improved.The addition of abrasive additives and hard particles reduces the porosity and friction coefficient,and improves the wear resistance of enamel.The increase of anchor points and dendrites at the interface significantly enhances the adhesion of enamel.The addition of ceramic particles reduces the difference in thermal expansion coefficient,enhances toughness and oxygen resistance,thereby improving the high temperature protection performance of enamel.This paper summarized the research on the influence of additives on corrosion resistance,abrasion resistance,adherence and high temperature protection performance of enamel,and made a summary analysis,which had certain reference value for the subsequent experimental research.
