Now when I go out into the street and look from house to house, the yard of each house is full of wheat stalks, and I can see a lot of harvest at a glance.

Although the labor efficiency is low, this cold season has to be busy for wheat threshing, and there is nothing to worry about when you have food.

Lin Yan's heart relaxed a lot, the food problem was finally preliminarily solved, as long as people didn't starve, people had the energy to do something else.

The tung oil fruit has been sent to the laboratory, and a set of small tools for the Ye Zijia to make an oil mill has been made, and Mao Mu has been used as a helper for Lin Yan to squeeze the oil.

After the dried tung oil seeds are pressed, the oil yield is very high, dozens of catties of oil are squeezed, and the remaining tung oil seeds are put away and squeezed when needed.

Mao Mu watched Lin Yan take the brush and brush the tung oil onto the wood, "So you can brush it to be waterproof?" ”

"It should be, brush one layer to dry, try the effect, if it doesn't work, brush a few more layers of oil."

This is the first time that a test has been done to determine the waterproof performance of tung oil.

Tung oil dries easily, and the wood, which has been brushed with oil, dries quickly and is much smoother to the touch. Mao Mu put the plank in the water to observe, and found that it was really impermeable.

And there was no residue when he poured the water on it, it was slippery, and he was pleasantly surprised: "It's really possible." Just brushed with a layer of oil, and the effect is so good. ”

Lin Yan checked it carefully, "It's really good." The quality of this tung oil is good, and the effect of brushing a layer will come out. It's just that the taste is a bit big, so you have to dry it more to disperse the smell. ”

"After a while, the smell is gone, the important thing is that it can be waterproof, and the effect is very good. Existing wood products are usable. It's easy to use and it's so easy to use. ”

"There are still fewer tung oil, so I have to prepare more next year."

The two muttered, and Shi Zhi took the time to take a look at it, and he was also amazed. "It's just a layer of oil, but the effect is so obvious. Lin Yan, the boat you make has to be brushed again, so you are not afraid of leakage. ”

Lin Yan nodded, "I think so too." Why did you come here all of a sudden? ”

"I heard that you are doing a tung oil test, so I'll come and take a look. It's getting cold soon, and I want more people to go to the woodworking and smelter to make parts for the rack car, so that there will be more cars next year. Do you want to go and tell Ah Lan about them? ”

"Just say to Bai Yun, she is in charge of the carpentry factory and the smelter. Whether to report to the arbitral tribunal or not is up to Bai Yun to decide. ”

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

As soon as Shi Zhi left, Bai Chen came, and she also came to see tung oil. After seeing the effect of brushing the wood with tung oil, she said: "Can you also apply a layer of oil on the paper, so that it can be waterproof?" ”

"Theoretically, it is possible. But how to do it, you have to slowly grope for it, the oiled paper will be handed over to you, you will tell Hongling by the way, and the oilcloth will be handed over to her. ”

"Okay, I heard that the red spirit has made a new cloth, should we go and have a look?" Bai Chen hadn't seen the red spirit for a few days.

Lin Yan was curious: "Is it still sackcloth?" ”

"It should be, I heard that it is very fine and whiter, and she is preparing to dye the cloth."

"Dyeing? Are you sure? Lin Yan was taken aback, has Hongling already done this?

Bai Chen shook his head, "Just go and see." ”

Lin Yan thought about it, and he was 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 good for a while, so it is better to see the progress of Hongling.

She said, "Mao Mu, Bai Chen and I will go to Hongling, will you go?" ”

Mao Mu shook his head, he was not interested in the cloth, "You guys go, I'll continue to brush the oil and see the effect." ”

The two came to the garment workshop, and Hongxiu welcomed them in very warmly, "I'm so happy that you can come." Stay at my house to eat today, just to make dry noodles, and you can eat together. Speaking of which, Lin Yan would like to thank you, your aunt didn't hide her selfishness at all, she told all kinds of pasta practices, and our family was also wiped out. ”

Thinking about the wheat piled up in two rooms at home, Hongxiu smiled brighter, and no longer had to worry about food.

The family has already agreed to plant more wheat in January next year.

Lin Yan hurriedly said: "I don't dare to take credit, everyone grows so much wheat just to eat, and it is better to eat more patterns." ”

Hongxiu insisted: "It's because you have a good heart, and you think of everyone about what is delicious, and everyone knows it." With wheat, the family has enough food and no longer has to go hungry, and it's all thanks to you. ”

"Hongxiu is right, we all know Lin Yan's dedication and keep it in our hearts." Bai Chen smiled and agreed, "We're looking for Hong Ling, where is she?" ”

"Hongling, it's been a few days since I plunged into the workshop, you wait, I'll call her."

"No, let's go over and have a look." Lin Yan said busily.

Follow Hongxiu to the place, there are threads and cloths everywhere, very messy, and Hongling is staring at a tank.

Hongxiu said loudly: "Hongling, let's see who's coming." ”

Hong Ling turned his head and saw Lin Yan and Bai Chen, and said in surprise: "Why are you here, wait for me first, and it will be fine immediately." ”

"You're busy. I heard that you were dyeing cloth, so let's take a look. After Lin Yan finished speaking, he looked at Hongxiu, "You go and get busy, don't worry about us." ”

Hongxiu didn't stay, and told them not to leave in a hurry, and to eat at home at noon before turning around and going about their own business.

Looking at the black liquid in the tank, Lin Yan asked, "Is this going to be dyed black?" What do you use to make dyes? ”

"This is a dye that has been filtered after steaming with chestnut shells, and I have just started trying it, and I haven't dyed the cloth yet." Hongling had heard Lin Yan mention dyes before, and he had recently started to try, but he had not yet produced results.

"It's okay, the two of us are also on a whim, and when I think of you, I'll come over and have a look. You still need to study the cloth dyeing, and we can't help you with anything. Lin Yan said truthfully.

She hasn't opened the room of the science and technology museum for a long time, she hasn't gone out for the past two years, and the contribution value is almost at a standstill, and everything can only be slowly explored by herself.

When this cold season passes, it is still necessary to go out and walk around, strive to open a few more rooms, and get more technical information.

Watching Hong Ling put a small piece of linen into the dye vat, and after a while, the cloth did change color, but the water faded seriously.

The red spirit infects the fabric again, repeating it over and on.

Lin Yan was puzzled: "The cloth dyed like this will not fade after washing." ”

"Yes, I'm thinking of a way, how to make the dye adhere to the cloth without fading, it can't be done by infection alone, there should be some steps and additives, I'm looking for it."

Lin Yan encouraged: "Then you continue to work hard, I came to tell you that the tung oil is squeezed out, and how to make the oilcloth will be handed over to you." ”

"Oilcloth?" Hong Ling was stunned and looked at Lin Yan puzzled.

"It is a cloth that can be waterproof, moisture-proof, and moisture-proof, and can be used to block the rain on rainy days, etc., and is easy to scrub. Generally speaking, just soak the cloth in tung oil, you try. ”

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

Lin Yan nodded, "That's it." Try to make it when you have time, tung oil is in the laboratory, you need to go and get it. ”

Red Spirit nodded.

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