【摘要】 选用磷乌酸 ( PTA)作电子染料 ,对 EVA乳胶作各种染色处理 ,用透射电镜观察其结果 ,分析并比较了染液不同 p H值 ,不同用量以及不同染色时间和方法等对观察结果的影响 ,实验结果表明 PTA染色有助于胶粒核壳结构的体现 ,p H6.4PTA染色效果好。更多还原

【Abstract】 Dureng the amking samples for EVA emulsion phosphotingstic acid (PTA) be used as electron stacn under the different conditions, such as pH Value,,used amount, stain time and methold. The samples were observed with TEM. The results were analyed and contracled. The proper experience about dectron stain of EVA were found.更多还原
