摘　　要：为提高酸洗搪瓷钢的密着性能,研究了酸洗搪瓷钢密着性能的影响因素,包括烧搪时间、脱脂效能、表面色差和表面粗糙度,对不同脱脂程度、表面状态及粗糙度的试样进行涂搪和烧搪,并采用落球冲击法对密着性能评级。结果表明:在850℃进行烧搪时,烧搪时间从5 min延长至10 min,密着等级从2.0级提高至1.0级。同时,烧搪5 min时,脱脂不充分、保护渣增碳所致色差和降低粗糙度都会降低钢板和瓷釉之间的密着性能,其中脱脂不充分和色差的影响可通过延长烧搪时间至10 min进行改善,但延长烧搪时间后,粗糙度对密着性能仍存在显著影响。To enhance the adhesion performance of acid-pickled enameled steel,the factors influencing its adhesion performance were studied,including enameling time,degreasing efficiency,surface color difference and surface roughness.Samples with varying degrees of degreasing,surface states and roughness were coated and enameled.The adhesion performance was then evaluated using the falling ball impact method.Results showed that when enameling was performed at 850℃,extending the enameling time from 5 to 10 min improved the adhesion grade from level 2.0 to 1.0.Additionally,at 5 min of enameling,insufficient degreasing,increased carbon from protective slags causing color differences and reduced roughness all decreased the adhesion performance between the steel plate and the enamel glaze.While the effects of insufficient degreasing and color differences could be mitigated by extending the enameling time to 10 min,the impact of roughness on adhesion performance remained significant even with extended enameling time.
