摘　　要：为解决空气净化器中外观塑料面板频繁出现的ABS塑料螺柱滑牙问题,本研究通过不同种类单组分胶水(如瞬间胶、EVA热熔胶、厌氧胶、溶剂胶等)之间的测试对比,以确定相对最优的螺柱螺纹修复工艺方案。研究结果表明:(1)由于瞬间胶固化后具有相对更高的硬度和粘接强度,这证明其具备更大的内聚力,这使其相比其他单组分胶水在塑料螺柱螺纹修复的工艺过程中具备明显更突出的性能优势。(2)测试对比发现,3种瞬间胶均能满足塑料螺柱螺纹修复的要求,其中瞬间胶-A鉴于其更突出的材料成本优势,被优先考虑用于最终的螺纹修复工艺。(3)通过对比试验,确认了瞬间胶-A在不同温湿度条件下的完全固化时间t0以及胶水对塑料面板材料韧性的影响。在相同水汽压下,瞬间胶-A的完全固化时间随着温度的升高而减少,即瞬间胶-A的固化速度与空气温度呈现正相关关系。(4)瞬间胶-A会导致塑料螺柱韧性略有下降,但下降幅度不影响后续螺钉的二次固定。(5)本研究一整套塑料螺柱螺纹修复工艺的探究和应用,能够最终实现塑料面板的零报废和降低零件成本,并且能够对行业内频繁出现的塑料螺柱滑牙问题的解决起到很大的经验总结和启示意义。In order to solve the frequent problems of screw studs stripping in the ABS plastic panel of air purifiers,various types of single-component adhesive(such as cyanoacrylate adhesive,EVA hot melt adhesive,anaerobic adhesive,and solvent-based adhesive)were compared and tested in this study to determine the relatively optimal repair process for screw threads.The research results showed that,(1)Cyanoacrylate adhesive exhibited relatively higher hardness and bonding strength after curing,indicating greater cohesive strength compared to other single-component adhesive.This made it significantly more effective in the process of repairing plastic screw threads.(2)Among the three kinds of cyanoacrylate adhesive tested,all met the requirements for repairing plastic screw threads.However,cyanoacrylate adhesive A was prioritized for its superior cost-effectiveness in the final repair process.(3)Through comparative tests,the complete curing time t0 of cyanoacrylate adhesive A under different temperature and humidity conditions,as well as its impact on the toughness of the plastic panel material were confirmed.Under the same water vapor pressure,the complete curing time of cyanoacrylate adhesive A decreased with increasing temperature,indicating a positive correlation between the curing speed of cyanoacrylate adhesive A and air temperature.(4)Cyanoacrylate adhesive A caused a slight decrease in the toughness of the plastic screw studs,but this reduction did not affect the secondary fixation of the screw.(5)The comprehensive exploration and application of this plastic screw thread repair process in this study could ultimately achieve zero scrap rate for plastic panels and reduced part costs,and provide valuable experience and insights for addressing the frequent problems of screw studs stripping in the industry.
