Wholesale of detonating tube blasting needles in Fujian Province, blasting needle manufacturers for blasting operations

Plastic detonating tube detonating needle. The inside of the needle is made of a core, and the outer cavity is made of a specially made tube. Between two metal electrodes, a detonator is used to convert the electrical energy into spark energy to detonate the detonator. It is an electronic firing device that is suitable for various non-electric explosions. Used in engineering and pyrotechnics testing. At present, there are common detonating tube firing pins on the market, which have poor detonation ability and weak ignition, thus affecting normal blasting. Users are advised to choose carefully. , the usage method is as follows
1. Directly insert the firing pin into the non-electric detonating tube, then operate the power switch of the detonator, and turn the charging switch into the charging position. When the charging voltage is reached, the detonation should be operated. (Do not detonate at high voltage to prevent damage to the internal electronic components of the detonator).
2. When you need to connect the multi-conducting blasting bus at the blasting site, it is best to control the blasting bus within meters. Insert the firing pin into the non-conducting blasting tube in front, and then connect the two wires of the firing pin to the blasting bus. Then connect the busbar to the detonator output clamp (terminal), operate the detonator switch, and the voltage can be controlled to detonate.
3. It is recommended to use single-strand insulated copper and aluminum core parallel composite conductors for the blasting busbar (that is, parallel composite conductors with copper and aluminum cores, which can achieve the ideal blasting effect). The larger the model of the high-energy pulse detonator, the longer the blasting bus that can be connected (meters).
4. The non-electric detonating tube firing needle is a consumable accessory in blasting operations and is used for non-electric blasting (the detonating tube detonator has a very high voltage every time, which will cause damage to the needle. When fired, When the needle fails to detonate and generate sparks normally, you can cut off the damaged part of the needle and sand it with a grinding tool until it is close to the initial state before continuing to use it. (When the firing pin is inserted into the detonating tube for too short, a new firing pin should be replaced).
