Abstract
본 발명은 석절장에서 채석을 위한 발파용으로 사용되는 구상흑색화약의 제조방법에 관한 것으로, 종래에 고온에서 행해지는 광택공정에서의 안정성 및 내습성을 개량할 목적으로 안출된 것이다.The present invention relates to a method for producing a spherical black powder used for blasting for quarrying in stone mills, and is intended to improve the stability and moisture resistance in the polishing process performed at a high temperature.
즉, 본 발명에서는 상기의 광택공정을 생략하는 대신에 성형공정에서 성형완료후 최종작업의 단계로 발수성 물질로 0.1∼100㎛두께로 코팅하여 건조화시켜서 제품화 함으로써, 흑색화약으로서의 성능을 유지하면서도 내습성이 크게 향상되고 안정성이 증가되었을 뿐만아니라 공정이 단순화되어 작업환경 및 생산성의 향상을 함께 도모할 수 있는 매우 유용한 발명인 것이다.That is, in the present invention, instead of omitting the above gloss process, in the forming process, after the molding is completed, it is coated with a water-repellent material to a thickness of 0.1 to 100 μm and dried to produce a product, thereby maintaining moisture performance while maintaining the performance as a black powder. Not only has this greatly improved and increased stability, but also the process is simplified, it is a very useful invention that can improve the working environment and productivity together.
