赛璐珞胶片是一种化学制品，其主要成份为樟脑及酒精。根据制造厂方介绍，樟脑成份多少是胶片影响热涨冷缩剧烈变化的主要原因，如配合量适当，可以减少伸缩至极小，通过我们予加热处理办法的结果，亦证明其正确。以赛璐珞胶片测图的创议，是我院贵州工作站地质队钱康达同志提出的，但原胶片两面都是十分光滑，不能黏上铅笔及墨，以至如何上毛，能使笔迹粘上，是胶片能否测图的主要原因。该站在试验时曾委托贵阳市某照相馆，用某种化学胶，在原胶片上搽上一层待干后，片面即变光为毛，铅笔，墨印都可粘上，但该照相馆资产阶级营利思想作祟，不愿 Celluloid film is a chemical, its main ingredient is camphor and alcohol. According to the manufacturer’s introduction, the amount of camphor is the main reason that the film affects the rapid change of shrinkage and shrinkage. If the amount of camphor is appropriate, the shrinkage can be reduced to the minimum. The result of our heat treatment also proves to be correct. The idea of ​​using celluloid film mapping was put forward by Comrade QIAN Kangda, a team of geological workstations at Guizhou Workstation in our hospital. However, both sides of the original film are very smooth and can not be stuck with pencils and inks. As a result, Film can test the main reason for the map. The station has commissioned a test Guiyang City, a photo studio, with a chemical glue, the original film on a layer of paint to be dry, the one-sided light for the hair, pencil, ink India can be glued, but the photo studio Bourgeois profit-making ideas cause trouble, do not want
