Rostec has developed a new explosive

Concern "Tehmash" (part of Rostec) has developed a new emulsion explosive (EVW) "Sferit - DP", which is made in the form of cartridges in a polymer shell with diameters 32, 36, 45, 60, 75, 90 mm, the blog reports bmpd with reference to the press service of the company.

It is noted that there are no analogues currently used in industrial volumes in Russia.

“Sferit-DP” will allow the explosives to replace the TNT-containing explosives and emulsion explosives that are available today. According to experts, over the past twenty years, the Russian market of industrial explosives (VV) is experiencing a decrease in demand for TNT-containing explosives due to the rising cost of TNT, the strengthening of industrial and environmental safety requirements. And the main disadvantages of the existing emulsion explosives are the small detonation transmission distance, especially for small-diameter cartridges (Ø 32 - 36 mm), as well as reduced heat of explosion. ”- said the general director of the concern Sergey Rusakov.

According to the press service, the difference of the new explosives from most domestic emulsion explosives is as follows:

“The low water content in the emulsion (9 - 10%), as well as in the finished emulsion explosive (8 - 9%) contributes to an increase in the calculated heat of explosion of the emulsion explosives;

- the presence in the oxidative phase of a co-soluble fuel (carbamide) increases the detonation ability of the microdroplets of the dispersed phase, thus complicating the reaction of ammonium nitrate with sulfide-containing ores and rocks;

- the use of a physical method of sensitizing an emulsion with a polymer microsphere improves the susceptibility of an emulsion explosive to a pulse of primary means of initiation.

Compared to the TNT-containing cartridges, Sferit-DP has a similar level of blasting at a lower price, higher safety in use, environmental friendliness, and ease of transportation, storage and charging. "

The expected economic effect when using "Sferita-DP" will be 20% per cubic meter of the blasted rock mass.

At present, industrial tests of products in mines are underway.

Help press service: ""Sferit-DP" refers to industrial explosives of class II and is intended for the formation of charges on the earth's surface and in underground mines of mines - not dangerous for gas or dust, in ores and rocks of any strength - including sulphide-containing, with manual loading of dry drained and watered (any degree of watering and flow) of boreholes and wells, as well as an intermediate detonator for initiating charges of explosives with reduced sensitivity to detonation and overhead charges for cutting bliss Arita at temperatures ranging from minus 50-five to plus 50Sº ".

A cool thing to destroy informers on the VO site.

Well, well, and it can be used instead of yeast in baking bread, but nobody really knows how to do this ...

[Conductor]

I don’t know how anyone, but this "sausage" looks quite appetizing ... go to have lunch chtoli))

This is for you!

There’s nothing to write about industrial explosives. Then you’ll have an excursion into history. Write about shimoza

[AID.S]

There was an article about shimoza.

Perhaps not about this explosive, but not so long ago there was one story. In Ukraine, several chemists invented more powerful and cheaper explosives than regular TNT. And they were carefully lured with their developments to the west. But as a result, they with all their developments ended up in the Russian Federation. And they themselves didn’t want to help the states, and ours fared in time. So suspicions arose - was this story about spherical?

[dik-nsk]

apparently a good thing - you can dig wells, you need to include Pure Water in the program

I don't know how and to whom, but I really liked the chemical expressions. Against the background of the prohibition of "unprintable expressions" it sounded very fresh! Score plus (+)! It sounds like a song: "sensitization of an emulsion with a polymer microsphere" ... something like "boiling milk on a cold stove."

"- presence in the oxidizing phase of a co-soluble fuel (urea) increases the detonation ability of microdroplets of the dispersed phase, while hampering the reaction of ammonium nitrate with sulfide-containing ores and rocks; "

I have a suspicion that I had in mind the HMTD (hexamethylene triperoxide diamine), judging by the general description.

Good savings when using succeed. For example, if you take the federal rates for drilling and blasting to a minimum, then for a highway, if you need to blow a recess in a rock for a road trough, for example, in granite, per 100 cubic meters. this pleasure will be about 200 tyr. (almost 90% is the cost of ammonite)., taking into account the fact that of these 200 ty. 90% is the cost of ammonite, then we get that when replacing explosives the cost drops to 170 tyr., It seems like a little, but in terms of 10 cubic meters. already saves 000 tyr., i.e. 3 million. This is already good money, and if we take into account the construction of a hydroelectric power station in rocky soil, railway tracks, the development of crushed stone and stone in a quarry, then, with normal organization, there will be significant savings nationwide!

Sorry maybe ammonal? Simply ammonite it is a petrified shell of a fossil clam.

I remember that some colleagues removed a sharp toothache with a piece of trotyl-containing, a small piece in a hollow of a tooth and that’s all, it doesn’t hurt. True, the tooth was guaranteed Khan. And now, how liquid ?!

I apologize, just about ammonite - I didn’t know the explosive, I knew about the fossil.

[Sergey333]

Some sausage I used to think that ordinary sausage on store shelves is a chemical-type weapon of mass destruction in the manufacture of which not a single cattle was harmed, this article convinced me of this even more

[cosmos132]

Interesting - can you fish with her effectively?

[yar bear]

And how! The main thing from fish surveillance is easier to excuse oneself: is that what? And this, this is sausage. Change the main label.

No apologies, colleague, you can’t know everything in the world. :))

90% of the comments on this article are quite reasonable and adequate, I definitely note the friendliness of the interlocutors!
Received a lot of pleasure after working through the comments!
An article from the category of those that were published in the journal "Science and Life" during the Soviet Union, just a little bit of nostalgia ... I thank the author of the article and the commentators!
