It was getting late, and no one had been notified before, so old man Ding simply asked people to stay overnight in the village.

Wang Dazhu and others are all good at work, with tools in hand, whether it is bamboo bowls or bamboo slices, they are all growing at the fastest speed.

When the sky darkened, nearly a thousand rubber bowls had been placed on the rubber trees near the village.

The Ding family was arrogant and willing, and the villagers all treated them with the highest standards, and they were told by the village head to collect the glue in the future, so everyone's mouths burst into laughter.

Ding Xuewei wanted to test raw rubber directly, but he only knew how to make raw rubber. After preparing a big pot, he couldn't sleep well after the vinegar tank.

In the early morning of the second day, she got up before dawn, and rarely met Ding's father and son when she went out.

"Let's go, let's go and have a look first." Ding old man signaled Ding Lao Er to go to the kitchen to ask for a torch.

It was early at this time, but the general farmhouses basically lit up the cooking smoke.

Get down early to cool off.

"I'll lead you there." Hearing this, Village Chief Ma walked out of the kitchen, holding a torch in his hand.

The wooden bucket for collecting rubber was right next to the steps, and Ding Laoer simply carried the bucket.

A group of people went to the edge of the forest silently, no one had the idea of ​​speaking. When they got to the edge of the forest and saw more or less resin in the bamboo bowl in a dim way, they all seemed to have turned on the sound-on button.

"It's quite a lot, I thought it was one or two taels at most." Old man Ding hurriedly took down a bamboo bowl. No!"

"This bamboo bowl is a little smaller. I think it should be replaced with a bamboo tube." Ding Laowu felt that it was a pity that the resin was on his hands: "This resin is too sticky. It should be better to stick windows with it than batter."

"We use it to glue the windows in our village. However, the windows glued with it have a disadvantage. They don't last long, and they have to be replaced in three or four months. This thing is very sticky when it is wet, and it will be brittle when it dries." Ruo Fei If they want to save an extra morsel of food, they will definitely not go to such trouble!

Village Chief Ma has obvious intentions, and everyone in the Ding family has a clear mind, and it can be said that they understand everything.

When carefully lifting another bowl of resin, Ding Laoer sighed: "No wonder it didn't spread!"

Rubber tree resin can't even stick to windows, so can plastic bottles still be used?
How long can it be used after it is successful?
With a thought, the father and son all turned to Ding Xuewei.

In the dimness, I saw her pulling the resin in the bowl with a stick.

Compared to them, Ding Xuewei at this meeting can be described as calm.

The rubber has been found, and it cannot be solidified, so even the windows must be disgusting, so let's talk about plastic bottles!

"Be careful, don't get your clothes on."

Ding's father and son three: "..."

They are the ones who co-authored it!
This matter, I really can't blame Ding Xuewei, if she can't maintain a normal mind, she will fail in the end, and she has to scratch her heart!

"Grandpa, grandpa of the village chief, you two just watch."

Both of them are not young, so they have to be more careful in this forest.

Those who are blind and blind, don't care about one and lose the other.

Ding Xuewei thought that both of them could only understand, she was not in a hurry and they were in a hurry.

"Just do what you want." Old man Ding said that she didn't need to worry about it.

Village Chief Ma smiled: "Don't worry."

Don't worry, the two old men don't intend to listen to her. Fortunately, the sky is gradually opening, and after half an hour of distraction, they don't need to pay more attention to them.

Ding Xuewei's family got up early, and Wang Dazhu and others were not too late. People arrived as soon as the sun opened. The problem was, they had already eaten.

Handing over the work of harvesting rubber to some people, let some people continue to make bamboo chips, and some people cut bamboo tubes again. Ding Xuewei led old man Ding and his son and village head Ma to go home and fiddle with it.

The Ma family didn't go to the field today, and they were all waiting to help, but there were only two barrels of resin, and they were not needed at all.

When Ding Xuewei poured two jars of vinegar into the resin barrel and said that he just had to wait, the sons of the Ma family couldn't sit still.

"Father, how about I go to the fields?" Boss Ma asked.

After the flood, their life was considered stable, but the hail taught them a lesson.

Even the lazy people in the past are very active in the fields now, not to mention the hardworking Ma family.

Although Village Chief Ma understands the importance, it is not a problem to wait like this.

"You are at home, let the second and third go."

Ma Laoer and Ma Laosan didn't express their opinions when they heard this, they happily took the hoe and went out.

Not long after they went out, Wang Dazhu and others came to deliver glue.

The ones that had been added with vinegar had already begun to separate. Ding Xue was confident about this process, and poured the vinegar into the resin buckets one after another. After the last bucket of resin was delivered, he added all the remaining vinegar.

The vinegar made by villagers in the village is fruit vinegar, which is not as acidic as formic acid. She is not polite when it comes to measuring, but even if the amount is increased, the reaction between fruit vinegar and resin is relatively slow!

Fortunately, slow to slow, the effect is still there.

"Xuewei, these two buckets should be enough."

Ding Laoer, who was asked to pay attention to the water layer at all times, reported after repeated confirmation.

Ding Xuewei, who was talking about the natural separation method with Village Chief Ma, hurriedly approached.

The first two barrels of the test have a larger layer than the later test, and the others are only five or five at most, and these two barrels have reached three to seven.

She can't remember the specific rubber production rate. The climate here is quite different from the rubber plantation she visited when she was a child, and it is not practical to compare the two.

Simply, she let the glue go.

I won’t talk about tools, I don’t have anything I want.

If you want to get rid of the moisture in the gum as much as possible, there are many ways to use acetic acid.

Acetic acid is not as corrosive as formic acid, so it is less irritating to the hands, and there is no need to worry about any sequelae.

According to Ding Xuewei's instructions, Ding Laoer first poured out the floating water, then covered it with a coarse cloth, and after filtering the remaining water, directly put it on the millstone to press it.

The Majia stone mill is not small, and three people moved it. In just 2 minutes, the rubber wrapped in coarse cloth could not squeeze out a drop of water.

"This~ Dad!"

Tearing off the rubber sheet that was pressed into thin sheets, Ding Lao Er's eyes were full of question marks.

This thing is not a little different from a plastic bottle, but it feels somewhat similar to the raincoat that Ding Xuewei sisters wore back then.

Compared with plastic bottles, raincoats are more useful in the eyes of Ding Laoer.

No, I accidentally forgot about Ding Xuewei, and the things were delivered directly to old man Ding.

"This~" Old man Ding turned his eyes after touching it, and looked at Ding Xuewei.

Ding Xuewei didn't even need to use his hands, he knew at a glance that this tofu-like thing could be used.

At least half of the glue has been made, and how to turn it into practical objects such as plastic bottles and raincoats is a matter for the future.

"It's not dry enough, let's dry it."

As soon as he joined hands, Ding Xuewei groped carefully, and after confirming the basic viscosity and toughness, he spread it out to dry.

It's just a vinegar, and the resin that was disgusting has changed its form. Although the stickiness is still sticky, it's not the kind of annoying sticky sticky that sticks to your hands, body and clothes, which is difficult to remove, but a controllable one. , the feeling of being able to artificially control.
