Unleaded delay nonel detonator

An unleaded delay nonel detonator belongs to the field of blasting supply for civil use, which comprises a tube. The unleaded delay nonel detonator is characterized in that a high explosive, a primary explosive, a delay element and a seal plug are sequentially arranged in the tube. A nobel tube is disposed in the seal plug and connected to the delay element which consists of an aluminum tube and delay powder filled inside the tube, and a plastic layer is laid on the outer surface of the aluminum tube. The unleaded delay nonel detonator avoids environmental pollution caused by heavy metal lead, enhances delay accuracy of a delay nonel detonator and lowers the cost of a nonel detonator. Meanwhile, the delay nonel detonator can be produced either in an integral structure or in a split outside-delay structure, and delay time is not affected by the tube length of a plain detonator and can be greatly prolonged so as to meet the requirements of specific users.
