Description
Maxel®
Instant is an instantaneous electric detonator. Maxel® Instant
legwires are two single cooper wires covered with good electric insulating
polyolefin. The end of legwires is protected by plastic cap from corrosion and
stray current.
Maxel® Instant is designed to primarily initiate
the blasting network or initiate the inhole explosives instantly.

Instruction for use
l The detonator shall be checked before use. The
detonators with serious erosion at its surface and lead wire and the break
short circuit resistances beyond their limits shall not be used.
l Before connection, the scale on the wire at the
connection portion shall be removed with emery cloth and shall be securely
connected. Then wrap the connection with insulated tape to avoid grounding so
as to ensure good conductivity.
l There should be no electric leakage in the instrument
and apparatus used in the spot, and the acting current of the special
instrument for measuring resistance can be more than 30mA.
l The electric detonator shall never be touch
electrified objects. The operation shall never be performed under the
circumstance of strong electromagnetic field.
l Only the leg wire can be hold while measuring
resistance and the detonator must be in a protective device.
l It is prohibited that one hand hold the detonator body
with the other hand pulling the wire so as to avoid accident.
l It is prohibited that the detonator body is hold
entirely by hand during the operation so as to avoid accident.
Handling, transportation and storage
l During handling and transportation, the product should
be handled with great care, and shall never be dropped, knocked and impacted
and shall be far away from heat source.
l The detonators shall be kept in a dry and naturally
well-ventilated storeroom equipped with lighting arrester.
l For the unpacked detonators, if they all cannot be
used soon, it should be kept back the package and stored into a dry storehouse
to avoid moisture absorption.
l The shelf life is one and half year in the originally
package.
