When Malin actually made a raincoat, he realized that he had thought it was simple...
Gasoline does dissolve natural rubber. After several hours of dissolution, the raw rubber cut into slices is basically dissolved in gasoline.
Then, Marin asked the tailor to make raincoats of later generations, made of linen, with a hood. Moreover, there was a brim of a hood that blocked the rain in front of the hood.
Throw the cut linen raincoat into the natural rubber gasoline solution and soak it thoroughly. Then, take it out and dry it, rinse it clean, and wash the gasoline...
The raincoat made is free of any problem when testing the rainproof performance. But the fire protection process...
After all, it is a raincoat made of gasoline. Gasoline is a super flammable substance. A raincoat that has been soaked in gasoline for a long time will immediately be like dry firewood when it comes to fire... Maybe it is a little more active... Then, the raincoat quickly becomes a fire coat...
"Flame Wind Coat..." Marin suddenly remembered a piece of equipment in a certain game...
This kind of clothing, when worn on people, encounters fire attack...
Forget it, let's not mention it... Marin was very frustrated...
"It's better to follow the original history..." Marin decided to act as a chemist and create the rubber solvent that made raincoats in history - carbon disulfide...
Speaking of which, carbon disulfide is also flammable. However, the boiling point of carbon disulfide is lower than that of gasoline, only 46.5 degrees. The warm water in the bathhouse can reach this temperature.
After soaking the raincoat, soak it in warm water at 50 degrees to absorb the carbon disulfide gas in the raincoat. Because this temperature exceeds the boiling point of carbon disulfide.
What's even better is that there seems to be a cold vulcanization technology in the vulcanization of rubber. The method is to dissolve the raw rubber in a carbon disulfide solvent with a small amount of sulfur chloride added. This vulcanization method is generally the vulcanization of film products.
It does not use rubber latex to heat it, which is very convenient. Moreover, in one step, you can vulcanize rubber or make raincoat film.
In addition, because of vulcanization, there is no problem that the raincoat made of raw rubber is not heat-resistant. After all, vulcanized natural rubber is heat-resistant, corrosion-resistant, wear-resistant.
Thinking of this, Malin didn't feel troublesome and immediately started to develop carbon disulfide. As long as it was done, it could directly make a mature raincoat.
As for how to make carbon disulfide...
After thinking for a long time, Marin took a look at the introduction from the chemistry class from the depths of his memory - using charcoal powder and sulfur to heat it to above 800 degrees...
This is easier. Marin sent someone to build a larger sealed steel furnace. After obtaining carbon disulfide, it is collected through the pipeline. The pipeline is arranged longer and surrounded by cold water. In this way, after the carbon disulfide gas cools below 46.5 degrees, it will turn into liquid and flow out. Then, Marin can be collected and used to dissolve raw rubber blocks.
As for the toxic gas leaked from carbon disulfide, Malin said it was not a problem. Because when he was working on aquamarine, he used activated carbon and elephant skin to create a gas mask. As long as the workers are careful, it is still safe. Of course, this production base must be kept away from residential areas to prevent gas leakage from poisoning the residents of the East Coast...
...
With Marin's full theoretical support, the production of carbon disulfide is not difficult. Soon, Marin collected a lot of carbon disulfide liquids. Although the purity is not high, the work he has to do has very low requirements for the purity of carbon disulfide. Then, modern raincoats were made, all of which were cold vulcanized rubber skins, not afraid of rainwater or high temperatures...
After this raincoat was made, it was limited to equip the officers of the Sixth Army, and then given to the British noble officers. As for soldiers, it was enough to weave a little straw. Moreover, the strawcoat has a certain protective power...
What Marin didn't expect was that the later style of raincoat he made seemed very popular. This modern raincoat similar to a windbreaker, a hooded and trouser, and with long leather boots, was so fashionable. Moreover, you are not afraid of it or not...
The first person to ask for a raincoat was Angela. She asked for a red windbreaker-style tug-back raincoat paired with pink leather boots, and walked out without any impact on rainy days. Then, Angela fell in love with walking in the rain - wearing a raincoat with a windbreaker...
Even if it was not raining, wearing this kind of windbreaker and taking off the cap would be able to wear it at that time. With the Grand Duke Angela taking the lead, the senior nobles of the Beihai Kingdom followed suit and asked Marin for this kind of rainbreaker with the tug of windbreaker. Of course, the colors must be different.
Women's are simple and rough - they need red or pink, while men need to do it casually, either gray, black or blue...
Moreover, in this era, dyes were basically extracted from plants, and some were extracted from minerals and animals, such as cochineal insects. Therefore, dyes in ancient times were also relatively expensive. The main reason was that it was difficult to collect. Unlike later generations, chemical means were used to obtain synthetic dyes of multiple colors, which was cheap.
In the past, the cheap red and blue, which were generally cheaper in later generations, were very high-end dyes and more expensive. For example, red, the most important red in Europe now, is extracted from red flowers or made of cochineal corpses.
Among them, the dye used in the red uniforms of famous lobster soldiers in later generations was mainly made of the corpses of female cochineal insects. This cochineal insect generally parasitizes cactus in dry tropical and subtropical areas.
Europe obviously does not have a dry climate suitable for cactus growth, so now European carmine is generally imported from the North African desert or West Asia.
Of course, Mexico is also a region where cactus is abundant. Later generations, Mexico was even called the country of cactus and was also a major producer of cochineal insects. Anyway, Marin planned to vigorously promote the cultivation and production of cochineal insects in the arid areas of Mexico.
This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Speaking of cochineal insects, the British also did a stupid thing - they introduced cactus in arid Australia to cultivate cochineal insects. As a result, cactus actually breeds wildly in Australia like rabbits, becoming a famous invasive plant, and like rabbits, it has become a huge disaster in Australia...
Marin doesn't have to do such stupid things. As long as he occupy Mexico, the country of cactus, he will not have to worry about cochine.
Blue looks like there are more indigo grass in Scotland. For example, when Scottish hero Wallace resisted the British invasion in the early years, he used the blue juice of the local indigo grass to apply on his face, known as the "Celtic Indigo Raider", which is fierce...
But indigo grass requires a lot of land to grow, and no one is willing to use precious land to grow this thing. Moreover, indigo grass has low blue juice content...
"By the way, Prussian Blue!"
Marin suddenly remembered a dye that was not expensive. The most important thing was that he knew how to produce it. Unlike most dyes in later generations, he didn't know how to produce it.
Only when Marin happened to read the legend of Prussian blue, because it was an interesting historical story, did he know how to produce Prussian blue.
Speaking of which, the production method of Prussian blue is very simple - it is to first mix wood ash and cow blood and roast it, then use water to soak the roasted substances, filter out the insoluble impurities, and then remove the yellow crystals from the solution. Then put this yellow crystal into the ferric chloride solution, and a bright blue precipitation is produced. This blue precipitation is a very excellent paint - Prussian blue...
Prussian blue is bright in color and does not fade easily. In addition, the cost is not high. After this dye appeared, the Prussian army began to use this Prussian blue to dye the military uniforms. Because the dye is of good quality and cost, it is a very good choice for military uniforms. It was not until before World War I that the naughty child of Virginia submissive to Prussian blue and changed the German army to earth gray.
Of course, we can't blame Wei Er. Because World War I is already the era of trench warfare. Everyone lies in the dirt pit all day long, with dirty and gray military uniforms that match the trenches. If the Prussian blue military uniforms are dirty in the trenches, it is easy to see if they are dirty in the trenches...
...
Thinking of this, Marin laughed - there was another way to make money! Even if the most primitive method is used to produce Prussian blue, the cost is not high.
For example, wood ash is available in every family. As long as the soil stove is used, there will be wood ash. And cow blood, this thing is not easy to find in China because cattle are not allowed to be killed there. But in Beihai, Marin imports tens of thousands of cows from Crimea every year, part of which is used to cultivate the land, and a considerable part is used to slaughter beef. Therefore, cow blood is absolutely indispensable and the cost is not high. Iron chloride is not a rare thing, and it is easier to make. With Marin's chemical knowledge, it is still very easy to do. In this way, there is no problem in making Prussian blue.
