笔者在工作实践中用透明胶带提取显现灰尘指纹,效果较为理想,现介绍给同行参考。透明胶带胶面的粘性,决定了其附着能力极强。用胶带粘取灰尘指纹,灰尘会附在胶面上。在胶面上再洒上粉末,粉末会在无灰尘的部位牢牢地吸附住。有灰尘的部位,粉末附着在灰尘上,由于灰尘溶于水,在水中灰尘及上面的粉末就会被溶解掉,而无灰尘的部位不会被溶解从而显出指纹。具体方法可用透明胶带将灰尘指纹提取下来,在其上面均匀地洒上粉末,或者将粉末倒在一个盛水的平盘里,粉末就会均匀地浮在水面上,再用胶带(胶面朝下)在表面浸一下取出,胶
The author in the practice of using transparent tape to extract the appearance of dust fingerprints, the effect is more ideal, are introduced to the peer reference. Scotch tape adhesive surface, determines the adhesion of its extremely strong. Stick the dust fingerprints with tape, dust will be attached to the plastic surface. Sprinkle the powder on the adhesive surface, the powder will be firmly adsorbed live in the dust-free parts. Dusty parts, the powder attached to the dust, the dust dissolved in water, the dust and the powder in the water will be dissolved off, while the dust-free parts will not be dissolved to show fingerprints. Specific methods can use transparent tape to pick up the dust fingerprints, sprinkle the powder evenly on top of it, or the powder poured into a flat plate of water, the powder will be evenly floating on the water, and then tape Under) Remove the surface dip, glue
