Electric detonators fusehead

Sipalin AOM. Ger trade name for the methyl-cyclohexyl ester of adipic acid. It was incorporated in solvents for NC (such as 75/25 butyl acetate/ethyl ale), the soln being used to coat electric detonator fuseheads by a dipping procedure. The Sipalin resulted in a NC varnish coating which was less permeable to moisture and less readily cracked... [Pg.341]

Excitation time. In firing electric detonators, the interval between the application of the current and the firing of the fusehead (see p. 112). [Pg.198]

Electric detonators are also used for detonation of high explosive charges. They are similar in design to other types of detonators except for the presence of an electric fusehead consisting of a bridgewire made of chromium and nickel. The bridgewire is covered by a heat-sensitive pyrotechnic mixture protected by varnish insulation. Standard fuseheads have electrical resistance of 1.2 to 1.4 ohms and... [Pg.50]

The lead salt of mononitroresorcinol was in use in electric detonators for making fuseheads. Some of them may be composed of this salt and dextrinated lead azide [159,160]. [Pg.259]

Electric detonators are either of instantaneous or delay action. The electric detonators with delay action have a delay element between the electric fusehead and the initiating mixture. This element provides a half-second, quarter-second or millisecond delay time. [Pg.6]

J.2.5 The ignition system is composed of an electric fusehead of the type commonly used in low pressure detonators, together with a 13mm square piece of primed cambric. Other fuseheads with equivalent properties may be used. [Pg.149]

Fusehead or Electric Matchhead. A (lashing (igniting) element used in electric blasting caps and detonators. It is a combination of bridge wire, igniter bead (drop or cylindrical chge) and lead-in wires. There are several types, and die following are described in Vol 4 of Encycl ... [Pg.631]

Priming compositions or priming mixtures are sensitive explosive mixtures that are designed to produce a flame in a particular application. They are most often mixtures containing a primary explosive as one of the components in such a form and amount that ensures the inability to initiate detonation of the mixture. The role of the primary explosive is to sensitize the mixture to external stimuli, not to make it detonatable. Priming mixtures are used in percussion caps for ignition of gun powder, on electric fuseheads, delay elements, etc. [Pg.5]
