N-A-A Chapter 118
Chapter 118
"Feces are made into soap, the fruit is lost to what you think, that thing can... Wait a minute!
Lu Zhe was surprised, and the survival manual said that there was really a country that used this thing to make soap.
"I leaned on, unexpectedly... It's true!
"Wouldn't you?" The five girls, including Shen Bing, all exclaimed!
Lu Zhe said solemnly: "In the southern foothills of the beautiful Himalayas, another ancient civilization adjacent to us not only uses cow dung to make soap, but also uses
it to make it..." Lu Zhe waved his hand:
"Forget it, that's disgusting!"
"Lu Zhe, is this really good?"
"Curiosity is hooked!"
"Although disgusting, let's say the answer, half of the words are dead."
Several girls looked at Lu Zhe with fear and curiosity.
Lu Zhe sighed: "The method of drying and grinding cow dung into powder and applying it to your teeth to brush your teeth is not hygienic at all, and it is easy to infect E. coli!" So please don't be curious about this, right?
Several girls were stunned.
Sure enough, and Ah Sanbi Chongkou, Grandpa Bei De Ye is a younger brother.
De Ye Beiye at least had to survive, but people simply like to do this, and there is something better that you don't have to obey?!
Shen Bing sighed and said, "Lu Zhe, this won't really be your way to make soap, right?!"
"Of course not!"
"So what's your solution?"
Lu Zhe said calmly:
"Mix vegetable oil and animal oil, add some emulsifier, flavor enhancer, pigment, and finally add sodium hydroxide, let it undergo a saponification reaction, and finally pour it into the mold to dry for a month, this is the soap I want!"
The five girls were stunned, and five pairs of big eyes blinked.
"Accidentally, this method turned out to be so normal!"
"It sounds... It's not disgusting at all!
"It's pretty tall."
"Are you sure it's feasible?"
"What he said must not be complete!"
"So, we can't make this soap at all, right..." Lu
Zhe thought for a while: "Actually, it's not true!" We can take stock of the supplies, see what is missing, and look for items that can be replaced.
Ning Shu thought for a while: "Animal oil is not difficult to get, you can use bear oil, you can also use lard oil!"
Lu Zhe nodded: "That's right!
Lin said shallowly: "What about vegetable oil?
Lu Zhe picked up a palm fruit and said, "Isn't there two clumps of palm fruit, there are many ways to refine palm fruit into palm oil."
Jiang Yao pondered: "Where to get the emulsifier?"
Lu Zhe said: "There is still some dama resin, which is a natural emulsifier, and it is itself a dipterocarp plant, and it is also a natural fragrance agent!"
Tang Xiaoguo said, "What about the pigments?
Lu Zhe replied: "The palm oil that has not been discolored itself is the color of the aunt, and the soap made should be the girl's favorite pink."
Tang Xiaoguo protested: "Do you have any opinion on pink?"
Shen Bing thought for a while: "So, the raw material is only sodium hydroxide!"
Lu Zhe took out the bottle of salt with his left hand, and picked up a lemon with his right hand: "We have table salt, we have batteries, how can there be no sodium hydroxide!"
Shen Bing was stunned: "Electrolyzed salt water? Is this okay?
"It doesn't cost money anyway, so why not give it a try?"
"But... What about molds?
"This one is simpler!"
Lu Zhe took out a piece of bamboo that was supposed to be used as firewood: "The empty groove of the bamboo core is the best mold!"
Shen Bing's eyes widened suddenly, and she suddenly realized a problem:
unknowingly, she had gathered all the elements for making soap!
"So, we can make truly natural soap?!"
Ning Shu thought for a while: "No, I remember that sodium hydroxide is a strong alkali, it will burn hands!" "
The burning ability of the sodium hydroxide solution synthesized by soil electrolysis is not very strong, but it can carry out saponification reaction, in order to ensure absolute safety, the soap liquid is done and left to stand for a month, which is basically harmless to the skin." And during this month, we can overdo it with pancreas.
Several girls looked at each other, and Ning Shu said excitedly: "That is to say, from now on, we will live a day where we can wash our clothes and faces with soap?"
Lu Zhe nodded: "After waiting, you can also use the finished soap and warm water to boil, and then add the juice of hair care and skin care plants to make hair cream and facial cleanser." "
Make soap!"
"We're going to make soap!"
"Maybe go back, we can also open a soap factory together!"
"Where to start, Lu Zhe!"
"First refine vegetable oil, peel off the palm fruit, boil it softer, then drizzle the water and mash it with a stone scoop, then dry boil and stir to remove the water, and finally squeeze it, you can do this step of mashing, the last step requires a lot of strength to squeeze, then I will do it!"
"Understood!" Lin Qiansha took the small book and wrote it down, and immediately got busy with his little friend.
Lu Zhe began to make sodium hydroxide by electrolysis of saline!
It is similar to the laboratory practice, but Lu Zhe set the operation location at the bamboo gate!
Because hydrogen and chlorine are generated during electrolysis, hydrogen is flammable, chlorine is not only toxic, but also rereacts with the prepared sodium hydroxide to form sodium hypochlorite.
Fortunately, there are not many generates, just as a poison, Lu Zhe opened the bamboo door slightly, so that the flowing air can quickly take away the generated gas.
Although the final formation is not pure sodium hydroxide, it is enough to complete the saponification reaction!
After an hour, the electrolyzed solution is made.
Ning Shu's side was also stuffed with crushed palm fruits full of stone scoops.
OK!
Lu Zhe took a stone and pressed it down, squeezing it hard!
With the blessing of powerful force, the palm fragments in the stone scoop were subjected to tremendous pressure, and a red oily substance was really squeezed out.
This is unshaded palm oil!
It is also the main edible oil for daily consumption by people in Southeast Asia.
The next thing is simple, vegetable oil animal oil is put in a steel helmet, boiled and stirred.
Dama resin was added sequentially to emulsify, flavor increase, and finally sodium hydroxide solution was added to initiate a saponification reaction.
Gradually, these oils turn into powder-white gel-like objects and give off a nice fragrance!
This is soap!
Lu Zhe split a piece of bamboo into two pieces vertically, placed it on the ground, used the trough in the middle of the bamboo as a mold, and poured the soap liquid into the mold.
"After waiting for more than ten hours, the soap will solidify, but it cannot be used at this time, because the saponification reaction is very long, and the sodium hydroxide has not yet fully reacted! The non-industrial method takes about a month, and the industrial method takes longer.
Jiang Yao said: "Don't be afraid, we can use pancreas now, the pancreas is used up, just seamless soap!" "
It took them most of the day to make the soap.
Busy for most of the day, it was already evening.
Jiang Yao mashed the sugarcane with a stone scoop and obtained a bottle of sugarcane juice, Shen Bing also processed the snake, the snake skin was peeled off, and the snake meat was placed on the banana leaves.
At this time, the wind outside the cave was even stronger, and the bamboo door was blown crackling, and Lu Zhe quickly brought all the pork in and squeezed the bamboo door with stones.
For dinner, Lu Zhe boiled the pig water with the snake, added salt and chili, and ate a meal of pig snake stew.
Eat and drink enough and continue to sleep.
In this way, they spent their twenty-sixth day on a desert island safely!
