【摘要】 目的　在硝化纤维素纸自动涂布系统中 ,对涂胶辊上的白乳胶涂层厚度 ( 0 .0 2～0 .0 2 5 ) mm及其均匀性进行检测 .方法　提出了一种利用红外线照在光亮的金属表面直接反射回的红外光强度与红外线照在液态白乳胶涂层 (厚度 ( 0 .0 2～ 0 .0 2 5 ) mm)上 ,并透过涂层再从金属表面反射回的红外线强度之差来提取涂层厚度特征信号 ,从而得到对应检测处涂层厚度信息 ,检测液体层厚度及均匀性的方法 ;给出了实现该方法的详实原理图 .结果　经实验调试 ,该方法可有效得到对应涂层厚度及均匀性的电信息 .结论　该方法是检测薄层能透光的液态涂层厚度及均匀性的好方法更多还原

【Abstract】 Aim\ In the automatic scrawling cloth system of nitrocel lulose element paper, the white latex thickness(0.02~0.025mm) and equality on th e gelatinizing roller are measured. Methods\ According to the difference between the infrared ray inte nsities that be reflected from the lucent metal surface and that be reflected fr om the lucent metal surface under the coating. Results\ Through the experimental debugging, this method has effec tively gotten electric information in accordance with the coating thickness and equality. Conclusion\ It is a good method for detecting the liquid state t hickness and equality of layer which light can penetrate.更多还原
