ПРОИЗВОДСТВО ПОРОХА: Внутри цехов, где искра статики — смерть

GUNPOWDER: How the 4,000-atmosphere hell behind the ramparts is tamed One kilogram of it turns into 900 liters of superheated gas in thousandths of a second, and its flash point reaches 2,600°C. This is smokeless powder—a controlled lightning bolt that propels projectiles at over a kilometer per second under the insane pressure of 4,000 atmospheres. Today, we'll visit a closed gunpowder factory, where one wrong temperature or a spark of static electricity can send an entire casing skyward. You'll see the hidden stages of defense production: from the nitration of cotton cellulose with acids in ice coils to 40-hour cooking in giant vats for stabilization. We'll show you the operation of powerful presses that transform gunpowder dough into endless cords, forcing them through steel dies under hundreds of atmospheres of pressure. We explore why grains are coated with graphite (similar to black caviar), how the geometry of the channels inside the grain controls the burning rate, and how ballistic bombs are tested before being sent to the military. 📍 Timestamps: 00:00 – Introduction: The Power and Properties of Smokeless Powder 01:05 – Inside a Powder Mill: Safety and Earthworks 02:17 – Why Smokeless Powder Replaced Black Powder: History and Advantages 03:43 – A Lab Accident: How Christian Schonbein Invented Nitrocellulose 04:56 – Manufacturing Process: Cellulose Nitration 06:20 – Stabilizing Nitrocellulose: Washing and Boiling 07:34 – Gelatinization and Pressing: Creating Powder Cords 08:56 – Pellet Cutting and Drying: How Grain Shape Affects Combustion 10:22 – Quality Control and Strict Safety at the Factory 11:45 – Smokeless Powder Summary 12:48 – C4 Production: NATO's Only Plant in Kingsport 14:32 – Composition C4: RDX and Other Ingredients 15:26 – History of the Holston Plant and Safety Measures 16:24 – Synthesis of RDX Using the Bachmann Method 17:30 – The Mixing Process (Slurry Coating) 18:34 – Forming M112 Charges: Extrusion and Cutting 19:42 – Laboratory Testing and the History of C4 22:53 – Dynamite: The Plant in Italy and the Properties of Nitroglycerin 24:45 – The Composition of Dynamite: Nitroglycerin and Kieselguhr 25:49 – Nitration Reactors and Emergency Release Systems 26:57 – The Most Dangerous Phase: Obtaining Nitroglycerin 28:30 – Mixing with Kieselguhr: Taming Nitroglycerin 28:58 – Forming the Iconic Yellow Charges 30:02 – Quality Control: Sweating Test 31:07 – Alfred's Story Nobel and the modern use of dynamite 32:56 – TNT: the factory complex and properties of trinitrotoluene 33:50 – The story of Julius Wilbrandt and synthesis from toluene 35:14 – Nitration stages in reactors 37:14 – Vacuum drying and granulation of TNT 39:40 – Safety: concrete shelters and automation 41:14 – Laboratory tests for stability and detonation velocity 44:11 – Tank barrels: extreme loads during firing 46:01 – Special steel: alloy composition for cannons 47:06 – Forge shop: radial forging under a 12,000-ton press 48:14 – Deep drilling: precision of a 6-meter channel 49:26 – Electrolytic chromium plating: protection from erosion 51:33 – Flaw detection, X-rays, and test firing At the Test Site 52:46 – Why Barrels "Die": Resources and Global Manufacturers 54:44 – Locomotive Recycling: 300 Tons of Steel in 72 Hours 55:43 – Train Graveyard and Reasons for Decommissioning 56:52 – Draining Technical Fluids: The Most Dangerous Stage 58:02 – Dismantling: Removing Valuable Assemblies and Engines 59:31 – Hydraulic Shears and Gas Cutting: Cutting the Skeleton 1:00:45 – Scrap Sorting and the Steel Cycle in Industry Did you like the power of this production?
