Abstract: PURPOSE:To obtain a center ignition powder tube free from the lag of ignition time and resistant to degradation such as moisture absorption by placing a coating layer of nitrocellulose and black powder on the inner surface of a cylindrical supporting tube composed of a completely burning material. CONSTITUTION:The objective center ignition powder tube has a double layer structure composed of a cylindrical supporting tube 1a made of a completely burning material and an igniter coating layer 1b (inner layer) composed of a mixture of nitrocellulose and black powder and applied to the inner surface of the supporting tube. It may have a three-layer structure having a layer (outer layer) composed of a roll-formed sheet 1c of nitrocellulose and a plasticizer applied to the outer surface of the double layer structure or a mixture of nitrocellulose and black powder applied to the double layer structure. The mixing ratio of the nitrocellulose to the black powder is 1:(9-2). When the mixing ratio of the black powder is larger than 1:9, the non-uniform application to the cylindrical tube or the separation of the coating layer from the tube may occur. If the mixing ratio is smaller than 1:2, the ignitability is deteriorated to an undesirable level.
