In 1862, Nobel helped his father develop high-standard nitroglycerin. He conducted repeated experiments to find a way to detonate nitroglycerin. Nobel first put a small amount of nitroglycerine into a glass tube, plugged the tube opening, then placed the glass tube into a metal tube filled with gunpowder, sealed the two tube openings, and inserted a fire tube into one of the tube openings. Nobel ignited the detonator and quickly threw it into the water. The dull explosion confirmed that Nobel had obtained the gunpowder he was looking for. After many experiments, Nobel discovered the principle of detonating nitroglycerin. Nobel was determined to find a way to control the explosion of nitroglycerin, hoping to create an ideal detonation device and discover the power of explosion. Nobel persevered in doing various experiments. During an experiment, Nobel's brother died. Nobel, who survived, completed his first epoch-making invention in 1863 - the mercury fulminate detonator. Mercury fulminate has great explosive power and sensitivity. It can be used alone when mixed with high explosives, potassium chlorate, antimony sulfide, etc. It will cause an explosion when it is hit by collision or friction. In 1864, Nobel patented this invention.
Nobel's invention was immediately put into practice. In a railway project under construction, the use of mercury fulminate not only greatly accelerated the progress of the project, but also saved millions of dollars. In 1865, Nobel established the Nitroglycerine Joint Stock Company, which was the first manufacturer in the world to produce nitroglycerin explosive. In 1867, Nobel developed yellow dynamite and obtained the right to invent it. The successful development of Nobel's yellow dynamite allowed nitroglycerin to be produced in a safer way and easier to operate. In 1868, Nobel discovered that mixing diatomaceous earth on the seabed or lake bottom with nitroglycerine in a ratio of 1:3 can form a safe high explosive. The sensitivity of the new explosive was much lower than that of high-purity nitroglycerin, but it was three times more powerful than gunpowder. He named the explosive "Dana dynamite." Later, Nobel discovered that diatomaceous earth is an inert substance. When mixed with nitroglycerin, although it reduced the sensitivity of nitroglycerin, it also greatly reduced the power of the explosive. So Nobel hopes to find a substitute for diatomaceous earth.
In 1875, Nobel accidentally discovered that nitroglycerin could be dissolved in collodion to form a colloid. This colloid could retain explosive power well, but it did not have the inherent instability of nitroglycerin. sex. More importantly, it has low production cost. Nobel named it "explosive glue". From 1879 to 1888, after nearly nine years, Nobel took greater risks and once again showed his talent to the world. He invented smokeless explosives. Nobel has become an unparalleled leader in the history of explosives.
