Chapter 1481： Oil and camphor

At the beginning, Marin did not know that the briquette was hot in Daming, but he soon knew. Because, Kong Tai sent a batch of local products from Taiwan. At the same time, news of honeycomb coal was also returned ...

As the governor of Taiwan, Kong Tai organized large-scale soldiers, mainly mainly rattan soldiers. When the rattan soldiers were trained, Kong Tai ordered them to begin expansion in the northern part of the island.

Faced with thousands of rattan soldiers and musketeers, the aborigines on Taiwan Island are not opponents at all. No matter how brave they are, it is difficult for them to break through the defense of the vine players. And if they attack each other remotely, they can't beat the musketeers ... and the loud noise of the muskets also comes with a threatening effect ...

Therefore, in the past two years, Kong Tai has sent troops and has hit the coastal area of ​​Tainan in later generations. And the Fanmin tribal alliance, the predecessor of the "Big Belly Kingdom" in the later generations, also defeated the expeditionary army of Kong Tai. The two sides fought in the Dajiaxi estuary generation of Taichung, and Kong Tai dispatched 2,000 rattan soldiers and 100 musketeers. The Fans of the Belly Alliance had gathered more than 4,000 people and launched an attack on the colonial army that had just landed. However, their attack failed to break through the defense of the vine soldiers, and the most brave soldiers rushing ahead were shot by the musketeers at close range, and then the people of the Belly League defeated and ran away. Subsequently, many defeated members of the Dadu Alliance were forced to flee deep into the jungle on the island. Kong Tai did not dare to go deep into the jungle easily, so he occupied the coastal area and the downstream area of ​​several large streams on Taiwan Island, and began to slowly develop and build fortresses, steady and steady.

Subsequently, Kong Tai began large-scale development in the occupied area. First of all, the most important thing that Marin attaches to nature is the oil produced from the sulphur pit. Although the daily output is only about 20 kilograms, but the accumulation of less and more, more than two years, but also accumulated about 15 tons of oil. Of course, the ship sailed to Panama City last year, and only brought back more than 7 tons of oil, which is one year's output. As for the output in the second year, it has not been accumulated yet and sent back.

Marin was very happy to see so much oil. After all, more than 7 tons of oil, even if the gasoline output rate is only 10%, can also extract more than 700 kilograms of gasoline. Used to burn enemy forces, you can let go.

With these oils, plus the continuous production of oil in the Galicia region of Poland, gasoline will definitely be enough in the future. Therefore, Marin decided to start developing a bed crossbow that could launch glass bottles filled with gasoline.

This year, ships are made of wood. If the wooden boat is made thicker, it may be able to resist the bombardment of iron ball shells. After all, planks are also very strong. However, the wooden boat is absolutely afraid of fire. In particular, gasoline burns such an indelible flame.

Originally, Marin planned to use a stone thrower to throw a simple cocktail burning bottle at an enemy ship. However, after testing, Marin found that the trebuchet wanted to hit the bottle with his target, really by luck ...

So, he thought of the bed crossbow ...

The heavy crossbow arrow of the bed crossbow is made into a post-mortem monkey, and the shaft of the arrow is tied with a molotov cocktail such as a gasoline-filled burning bottle. When the crossbow arrows were inserted into the enemy's body across a few hundred meters, the gasoline glass bottle tied to the arrow shaft was broken due to the impact, and the gasoline splashed on the enemy ship due to inertia ... Next, the bed crossbow was used to shoot rockets ... After one set down, the enemy wanted to keep the ship, it was almost delusional ...

Unless, the other party learned in advance that gasoline was present and prepared to cover the fire with sand. Otherwise, if you want to use conventional watering methods to extinguish the fire, you will definitely die ugly ...

Only, because the current oil production is very limited. Therefore, Marin generally does not use gasoline easily. Only when attacking the fortified city with wooden gates, or when decisive sea battles with the enemy are at sea, will this great weapon be sacrificed ...

...

In addition to the oil produced in the sulphur pit, the most important property of Malin on Taiwan Island is probably camphor ball. In the northern part of Taiwan Island, camphor trees that produced camphor were everywhere in the virgin forest in this era. After Kongtai sent troops to occupy the northern coast of Taiwan Island, he quickly relied on Daming craftsmen to harvest a lot of camphor trees and extract hundreds of pounds of camphor to send back.

After getting these powdered natural camphors, Marin was very excited. Because, his smokeless gunpowder research can continue ...

Previously, Marin only produced the first-grade smokeless gunpowder-B gunpowder, which is to mix nitrocellulose with 2% paraffin and passivate it. It was the first smokeless gunpowder in history.

However, the passivation effect of paraffin is general, and the smokeless gunpowder produced is easy to spontaneously ignite, leading to very serious accidents (historically, French steel warships were blown down by spontaneous combustion of B gunpowder, and the loss was very heavy). Therefore, in the period of World War II, everyone began to passivate nitrocellulose with more advanced passivating agents such as phenylenediamine.

But Marin doesn't understand chemistry, he won't get any phenylenediamine ~ www.novelhall.com ~ So, he can only use the most powerful natural passivation agent-camphor ...

Originally, Nobel, the explosive maniac, used camphor as a passivating agent to develop the Noh's smokeless gunpowder. It's a pity that his invention was a little late and he was born out of time. People B gunpowder production equipment are ready, will you adopt your new gadgets? Then, Nobel ’s invention was put on hold until the British learned Nobel ’s ideas and plagiarized their ideas ...

...

Then, Marin began to personally improve the smokeless gunpowder. He first used the old method to produce nitrocellulose particles containing 2% paraffin (the specific process will not be mentioned, so as not to be caught by the river crab like chapter 848). After obtaining granular nitrocellulose, Marin dissolved camphor with alcohol and soaked the granular nitrocellulose in the alcohol solution of camphor (nitrocellulose is insoluble in alcohol). After the alcohol evaporates, camphor covers the surface of the nitrocellulose particles, forming a film that hinders the rapid burning of nitrocellulose ...

Of course, Marin is not sure about the specific concentration. Therefore, he made dozens of different concentrations of camphor alcohol solution. Then, test the effects of various passivated nitrocellulose one by one.

Then, several testers tested the effects of dozens of smokeless gunpowder on the shooting range. After several days of testing, Marin finally got a better ratio.

Subsequently, Marin used this passivated smokeless gunpowder as the standard propellant for single-headed ammunition. In the future, in key battles, the one-shot bullets all used passivated smokeless gunpowder as propellant. This gunpowder is powerful, and after passivation of camphor, the safety is greatly improved, and I am not afraid that the shooter will be killed by accident ...

In short, the camphors sent back by Kong Tai helped Marin a lot ...
