岩矿制片中的干砂减薄新工艺

The New Technique for Making Thin-section by Dry Emery

利用空压机所产生的高压气流带动金刚砂干砂直接撞击岩石样品表面使之实现迅速减薄的目的,该法较传统的水砂手工减薄法具有效率高和劳动强度低的优点,同时避免了水砂减薄法中的脱胶、碎裂,或因矿物易溶于水而被溶解丢失以及因矿物吸水而使样品发生膨胀变形等弊病。

The high - pressure air emitted form the air compressor drives the dry emery impacting the surface of the rock samples directly to achieve rapid thinning of the rock samples. This new technique is not only more efficient and lower labor intensity than the traditional wet emery manual thinning method, but also avoiding the problems encountered by traditional method, such as degumming, fragmentation, dissolving of some mineral, expansion and deformation of mineral, etc.
