传统的磨制偏光显微镜用的岩矿薄片,是以光学树脂胶粘结盖玻璃,费工费料. 笔者从1974年开始,在磨制碳酸盐类岩石薄片时,将固体光学树脂胶用二甲苯溶解,制成光学树脂胶溶液,储存于磨口浸油滴瓶内.溶液浓度应低于市面出售的粘信封的胶水制薄片时,用滴棒将溶液滴在薄片上,让其自由浸润,待二甲苯挥发后,薄片上即留下一层极薄的树脂胶盖层,盖片工序即告结束. 此法制成的薄片与盖玻璃盖制的薄片,镜下观察效果完全相同,也能较长时间保存.如要挑取盖胶下的矿物作其他鉴定,只须用二甲苯棉签擦去部分盖胶即可. 溶解树脂胶的溶剂还可以是乙醇、乙醚、丙酮等.光
The traditional grinding of rock with a polarizing microscope chip, is based on optical resin adhesive bonding cover glass, the cost of work I began in 1974, the grinding of carbonate rock slices, the solid optical plastic with two gum Toluene was dissolved to prepare an optical resin gum solution, which was stored in a grind oil dip flask, and the solution concentration should be lower than that of commercially available adhesive-sealed glue-coated flakes, the solution was dripped on the flakes with a drip stick to freely infiltrate , To be xylene volatile, the sheet that is left a layer of very thin resin cover, cover process is over. The film made by this method and cover glass cover made of the same observation under the microscope, but also Can be stored for a long time.If you want to pick under the cover of the mineral for other identification, just use xylene swab to wipe part of the plastic can be dissolved solvent resin glue can also be ethanol, ether, acetone, etc. Light
