【摘要】：目的考察5種不同類型樹脂作為搪瓷用冷軋鋼板預涂層對最終搪瓷鋼制品性能的影響。方法在相同基板條件下,利用刮棒進行濕法涂覆后加熱固化法,制備具有相同單位膜重的5種不同樹脂的預涂層冷軋?zhí)麓捎娩摗２捎渺o電噴涂將瓷釉粉末均勻散布于預涂層冷軋?zhí)麓捎娩摫砻?再在馬弗爐中燒結成搪瓷鋼片。通過落錘測試和表面顯色法分析搪瓷鋼片的搪瓷密著性能和表面針孔率。結果與無涂層冷軋?zhí)麓捎娩撓啾?所選的預涂層樹脂都能不同程度地提高搪瓷層的密著性能,但不同樹脂在高溫下的熱分解速率差異以及溫度高于650℃后的熱分解殘留物的不同,會直接影響搪瓷層表面的針孔缺陷。經測試,最優(yōu)性能的預涂層可以將搪瓷的密著性能由無涂層的5級提升到1級,表面針孔率在薄搪瓷層的條件下控制在200個/m2以下。結論通過對冷軋?zhí)麓射摪灞砻媸┘泳酆衔镱A涂層,可以有效提高搪瓷鋼制品的密著性能。選擇綜合性能優(yōu)良的預涂層樹脂匹配合適的搪瓷層厚度,可以減輕或避免由預涂層熱分解引起的表面針孔缺陷。
[Abstract]:Objective to investigate the effect of five different types of resins on the properties of final enamel steel products as cold-rolled steel plate for enamel. Five kinds of precoated cold-rolled enamel steels with the same unit film weight were prepared. The ceramic glaze powder was evenly dispersed on the surface of cold-rolled enamel steel by electrostatic spraying. The enamel steel sheet was sintered in a muffle furnace. The enamel tightness and the surface pinhole rate of the enamel steel sheet were analyzed by drop weight test and surface coloration method. The results were compared with that of uncoated cold-rolled enamel steel. The precoated resin can improve the density of enamel layer to some extent, but the thermal decomposition rate of different resin at high temperature and the pyrolysis residue above 650 鈩，
