CZK - Časový rozněcovač ČaRoZ-60

ČaRoZ- 60 is an industrially manufactured time detonator. It belongs to the category of incendiaries. It is waterproof and can be used in all weather conditions. If it is to be used for underwater firing, it must first be ignited above the surface and then lowered under water. It is fully functional in the temperature range from - 30 ° C to + 40 ° C. It is designed for a burning time of 60 to 90 s. As a rule, ČaRoZ-60 burns in the range from 80 to 95 s (author's experience).




ČaRoZ- 60 consists of the following components:
- detonator Ž (it is already connected from the factory with the fuse by a watertight connection)


- zapalnice PVC (on one side connected with detonator Ž, on on the other hand with a friction lighter)


- friction lighter (is firmly connected to the lighter)


- detonator screw (it is threaded on the fuse and is intended for a fixed connection and storage of the time detonator detonator in the detonator well of the charge)




The friction lighter consists of the following components:
- tear-off cap (it is firmly connected to the friction wire by twine, after its tearing off, the ignition composition is ignited and the whole process of igniting the lighter is started)


- twine (firmly connects the tear-off cap with the friction wire)


- wing nut (it is firmly connected to the body of the lighter and serves for the correct attachment to the fingers when performing the shot)


- friction wire (works on the basis of a stone in the lighter and creates the primary spark needed to ignite the ignition composition)


- ignition component (after ignition, transmits flame to ignition)


- firing (lower part of the lighter, used to ignite the soul of black fuse dust)


- friction lighter body (protects lighter components from external influences)


- coupling (used to firmly connect the lighter with the lighter)


Method of using ČaRoZ- 60
In use, the detonator detonator is first inserted into the detonator well of the charge and secured by screwing in the detonator screw. For plastic explosives ( Pl Np 10 nebo [ url=/viewtopic.php] Pl Hx 30[/url]) detonator well and then the detonator detonator is inserted into this well. Subsequently, zapalnice will be developed so that it does not cross anywhere. Then the wing nut is firmly gripped in the fingers of one hand, the tear-off cap is unscrewed with the other hand so that it remains only caught on the twine. Subsequently, the friction wire is pulled out as smoothly as possible. This will ignite the ignition component in the friction lighter. From the ignition composition, the charge is ignited and subsequently the soul of black dust in the fuse is ignited. After burning the soul of black dust in its entire length detonator detonates the detonator and then the entire charge.




Packaging and transport
The detonators Ž of the ČaRoZ-60 time igniters are protected from external influences during transport by inserting them into special cases of five pieces each. Three such detonator cases are then packaged in a paraffinized cardboard box. The boxes are then stored in ten pieces in transport boxes measuring 44 x 30 x 24 cm.



Conclusion:
Due to its relatively small timing from 60 to 90 seconds, the ČaRoZ-60 timer is not very suitable for firing large charges. Burning time is too short to reach a safe distance from the explosion site. For this reason, it is not widely used for blasting work. During these activities, hand-made time detonators made of Ž and detonators, whose length is at least 120cm.
ČaRoZ-60 in conjunction with tritol charges of 200 g or 400 g is used primarily to destroy residual and unexploded ordnance during training, especially hand grenades RG 4, RG F1 a URG 86.

"třecí drát (funguje na bázi kamínku do zapalovače a vytváří prvotní jiskru, potřebnou k zapálení zážehové slože)", - tak takýto blud som už dávno nečítal..
Trecí drôt je pretiahnutý cez kovový kalíšok, v ktorom je umiestnená zážihová zlož, citlivá na trenie. Táto zlož následne zapaľuje ten nápal..
