survival in the wilderness

Chapter 139 Tung Oil
Now when I go to the street and look from house to house, the yards of each house are full of straw, and I can see a lot of harvest.

Although the labor efficiency is low, this cold season has to be busy with wheat threshing, and there is no need to worry about everything when there is food.

Lin Yan felt a lot more relaxed. The food problem was finally solved. As long as people don't go hungry, people will have the energy to do other things.

The tung oil fruit has been sent to the laboratory, and a small set of tools for Ye Zi's oil workshop has been prepared, and Mao Mu is used as Lin Yan's helper to press the oil.

After pressing the sun-dried tung oil seeds, the oil yield is very high. After squeezing dozens of catties of oil, the remaining tung oil seeds are put aside and pressed again when needed.

Mao Mu watched Lin Yan brush tung oil onto the wood with a brush, "Will it be waterproof after brushing it?"

"It should be. Apply a layer and let it dry. Try the effect. If it doesn't work, apply a few more layers of oil."

This is the first test to determine the waterproof performance of tung oil.

Tung oil is easy to dry, and the oiled wood board dries quickly and feels much smoother.Mogi put the board in the water to observe, and found that it was really impermeable.

And there is no residue after pouring water on it, and it is slippery. He was pleasantly surprised: "It really works. It only needs a layer of oil, and the effect is so good."

Lin Yan checked it carefully, "It is indeed good. This tung oil is of good quality, and the effect will come out after just one layer of brushing. It just smells a bit strong, and it needs to be dried more to dissipate the smell."

"The smell will disappear after a period of time. The most important thing is that it is waterproof, and the effect is very good. All existing wood products can be used. It is simple and easy to operate, and it is very easy to use."

"There are still few tung oil seeds, and we need to prepare more next year."

The two muttered to each other, and Shi Zhi took the time to take a look, and was also amazed. "It's just a layer of oil, but the effect is so obvious. Lin Yan, you have to brush every boat you make, so you won't be afraid of water leakage."

Lin Yan nodded, "I thought so too. Why did you come here suddenly?"

"I heard that you are experimenting with tung oil. I'll come over to have a look. It's going to be cold soon. I want more people to go to wood factories and smelters to make accessories for rack cars. Only next year will there be more cars. You said you want Don't go tell Alan and the others?"

"Just tell Bai Yun, she is in charge of the wood factory and smelting plant. It is up to Bai Yun to decide whether to report to the arbitration tribunal."

"Okay, then I'll go find Baiyun."

As soon as Shi Zhi left, Bai Chen came, and she also came to see Tung You.After seeing the effect of brushing wood with tung oil, she asked, "Can we also apply a layer of oil to the paper so that it will be waterproof?"

"Theoretically, it is feasible. But how to do it, you have to find out slowly. The oil paper will be handed over to you. If you tell Hong Ling by the way, the oil cloth will be handed over to her."

"Okay, I heard that Hong Ling has made a new cloth, why don't we go and have a look together?" Bai Chen also didn't see Hong Ling for several days.

Lin Yan asked curiously, "Is it still sackcloth?"

"It should be. I heard that it is very fine and whiter. She is going to dye the cloth."

"Dyeing? Are you sure?" Lin Yan was surprised. Has Hongling already made it this far?

Bai Chen shook his head, "You'll know if you go and have a look."

Lin Yan thinks about it too, and is not in a hurry.The effect of tung oil is very good, there are still many things to do next, and it will not be done well for a while, so it is better to see the progress of Hongling.

She said: "Momu, Bai Chen and I are going to Hong Ling's place, are you going?"

Mao Mu shook his head, he was not interested in cloth, "Go ahead, I will continue to apply oil and see the effect."

When the two came to the garment workshop, Hongxiu welcomed them in with great enthusiasm, "I'm so happy that you can come. I'll stay at my house for dinner today, and I happen to be making dry noodles, so you can eat together too. Speaking of this, Lin Yan would also like to thank you, your mother is not secretive at all, she told you all the ways to make pasta, and our family has followed suit."

Thinking of the two houses full of wheat at home, Hongxiu smiled brighter, and no longer had to worry about food.

Their family has already discussed that they will open up wasteland to plant more wheat in January next year.

Lin Yan hurriedly said: "I don't dare to take credit for it. You grow so much wheat just to eat it. It's better to eat more varieties."

Hongxiu insisted: "It's because of your kindness that you think of everyone when you have something delicious, and everyone knows it. After having wheat, the family's rations are all there, and they don't have to go hungry anymore. It's all thanks to you. "

"Hongxiu is right. We all know Lin Yan's contribution and keep it in our hearts." Bai Chen echoed with a smile, "We came to find Hongling, where is she?"

"Hong Ling, it's been several days since I plunged into the workshop, you wait, I'll call her."

"No, let's go and have a look together." Lin Yan said hastily.

Following Hongxiu to the place, there were threads and cloth everywhere, very messy, Hong Ling was staring at a tank.

Hongxiu said loudly: "Hong Ling, quickly see who is coming."

Hong Ling turned his head, saw Lin Yan and Bai Chen, and said in surprise, "Why are you here, wait for me for a while, and I'll be fine soon."

"You are busy with your work. I heard that you are dyeing cloth, so let's take a look." After Lin Yan finished speaking, he looked at Hongxiu, "Go and do your work, and leave us alone."

Hongxiu didn't stay either, and told them not to leave in a hurry, and had dinner at home before turning around to do her own business.

Looking at the dark liquid in the tank, Lin Yan asked, "Is this going to be dyed black? What did you use to make the dye?"

"This is a dye that is boiled and filtered from chestnut husks. I have just started to try it, and I haven't dyed the cloth yet." Hong Ling had heard Lin Yan mention the dye before, and recently started to try it, but has yet to produce results.

"It's okay. The two of us came here on a whim. When we thought of you, we came over to take a look. You still need to study the cloth dyeing, and we can't help you much." Lin Yan said truthfully.

She hasn't opened the room of the Science and Technology Museum for a long time. She hasn't been out in the past two years, and her contribution value has almost stagnated. She can only slowly explore everything by herself.

After this cold season is over, I still have to go out and wander around more, try to open a few more rooms, and get more technical information.

Watching Hong Ling put a small piece of linen into the dyeing vat and fish it out after a while, the color of the cloth has indeed changed, but the color faded seriously after passing through the water.

The red spirit infects the cloth again, repeating over and over.

Lin Yan wondered, "The cloth dyed like this will fade after washing."

"Yeah, I'm trying to figure out how to make the dye stick to the fabric without fading. Infection alone can't do it. There should be some steps and additives. I'm looking for it."

Lin Yan encouraged: "Then you continue to work hard. I'm here to tell you that the tung oil has been squeezed out, and I will leave it to you to make the tarpaulin."

"Oilcloth?" Hong Ling was taken aback, looking at Lin Yan puzzled.

"It is a cloth that is waterproof, moisture-proof, and moisture-proof. It can be used to keep out the rain in rainy days, and it is easy to scrub. Generally speaking, soaking the cloth in tung oil will do. Try it."

Hong Ling understood, "If you have oilcloth, you can make umbrellas, raincoats, etc., right?"

Lin Yan nodded, "That's it. Try to make it when you have time. The tung oil is in the laboratory, so you can get it if you need it."

Hong Ling nodded.

A few people were talking, Hongxiu came and called them to eat.Lin Yan and Bai Chen had no choice but to stay for a meal.
