The explosives are very very important

The explosives

In this page we will speak about some of the explosives
We ask the Allah of the powerful Most High that it guides us
* some of the explosives and a speed and their explosion
The black gunpowder the explosive speed is 300 - 400 metres / the second
The ammonium nitrate the explosive speed is 2500 - 2700 metres / the second
The Slourks of the explosive speed is 3500 - 4000 metres / the second
The Al Barougil of the explosive speed is 4500 metres / the second
To the mercury provisions the explosive speed is 4500 metres / the second
I bestow on the bullets the explosive speed 4500 metres / the second
As for the loom of the explosive speed is 4500 metres / the second
The Tnt of the explosive speed is 6900 metres / the second
The explosive speed comes at the end 7500 metres / the second
The Al Nirtouglsrin of the explosive speed is 7500 - 8000 metres / the second
The c boat 4 the explosive speed is 8000 metres / the second
The Rdx the explosive speed is 8350 metres / the second

* a sixth : the way of the explosion :
And the use of wicks and thunderbolts takes place in the explosion of the explosives charges and we clarify while follows the wicks kinds and the thunderbolts used in the explosion :
أ - the wicks kinds :
1. Ishtalia wicks ( the safety wick ) quickly 1 cm burns / second and he is an expression about a rope packed in the black gunpowder .
2.Water wicks and fast wicks
By - the thunderbolts kinds ( the bombers ) :
1.The detonator is Al Trqi
2. The electric detonator - and uses with it the electricity conduction wires and the battery of the electric explosion and from it a kind it explodes a momentary and another kind with timing .
* the security distances of the individuals for the explosion operations : :
The security distances of the living organisms in general for the different quantities from the explosives at holding the explosion operations she as the next if they were quantity the explosive is 15 kilos gram, the safety distance is 32 .A metre
And the security distance from 16 is to 30 kilos gram formation of 400 metres as for from 31 to 60 kilos gram then the security distance is 500 metres of course taking into consideration that the explosives are not containing on the splinters then we speak here about the security from the explosion wave only .
* the preparation of the most important acids that is used in the industry of the explosives :
First : the sulfuric acid :
The sulfuric acid is the battery water and that can be purchased easily from the batteries packing shops and he is available but a very few Btrakiz .
And so that we know its concentration follow what follows .
The density knows that it is the weight / the size is a permit so that we say that there is at us for example 100 boredom of the sulfuric acid and want that we know its concentration we are weighed 100 boredoms from it and we divide the weight on the size and see the result .
The sulfuric acid is the concentration of 90 %
Its density is 1.48 loves to all we will complete
And we measure against that .
And for its concentration we depend upon its heating in a glassware against the heat until its size is less to the two one thirds approximately after the ascension of white vapours and hence the acid is a center .
And for the dilution of the acid we add the acid to the water and not the reverse ..
A second : Nitric acid :
And he an acid getting it and especially in Palestine is difficult and for the other countries then it enables getting it the medical analysis centers and from the shops of the sale of the laboratories preparations and the schools laboratories and that can be prepared in an easy way but it requires a patience
The preparation is as follows
1 : we take 50 gram of the potassium nitrate and she as said a cheap agricultural fertilizer and getting it and not in it a thing was easy from the suspicion .
2 : and bring 40 boredom of the sulfuric acid the concentration of 70 % or more it does not harm .
3 : two containers from the glass Al Bairks against the heat piece of the cork of the test tube dam and piece of the glass in the form of an absorbent .
4 : a moderate flame source .
5 : a cold water or pieces of the ice .
The work way
We put in the first container the nitrate and we add to it the acid then we close the container and from a remoteness that put the container on the fire and at the second mouth to the pipette we put the other container problem whey was an ordinary glass we put over the pipette pieces of the ice that watches the rise of gas close to the yellowness from the test tube that we heat that this gas accumulates and it falls in the form of drops and she is the acid of concentrated Nitric very and this an illustration
The concentration of Nitric acid is 90 % when it is its density 1.84 gram to each cubic centimetre .
This and the Donor of success Allah ]
