Li Lu died half a month after he was in Dalinghe Fort.

There are still three days left until the stinging season.

Zhang Baiyong completed the sulfuric acid bleaching experiment explained by Zhu Shun ahead of schedule, and happily rode on a Liaodong horse to the workers' hall and found Zhu Shun, who was preparing for the land reform in Miyun County.

Zhu Shun learned that he had completed the sulfuric acid bleaching experiment, and had successfully built a paper mill, and that the steam machinery for the transformation into a steam factory had been installed.

He threw down the brush in his hand, put down all the cases at hand, and rode to the paper factory on the bank of the Chaohe River.

Paper mills.

The first thing Zhu Shun saw when he arrived here was a horse head built with cement, which had not yet been activated, and only a flat sand boat was docked alone on the shore of Ma Tou.

This is only temporary, and it is hard to imagine that it will be lively in the near future.

The paper mill has been hardened with cement and a system of drainage pipes that look clean and tidy.

Zhu Shun first went to check the foam pool, which is also the first process of papermaking.

The bubble ponds of the bureaucratic squire's workshop are basically some ponds dug directly in the mud, and these ponds have a large amount of impurities and sediment, which will cause a certain amount of pollution to the raw materials of papermaking.

The foaming pond of the paper mill is built with cement, and the foaming water in it is regularly discharged and replaced with clean water that has been steamed to remove impurities.

First of all, in terms of raw materials, the raw materials used in the paper mill are much cleaner than those in the bureaucratic gentry's workshop, and the quality of the paper will be improved a lot.

Zhu Shun walked to the side of the cement bubble pool and took a look at the cement bubble pool that looked like a small lake, and the water in it was indeed much clearer than the bubble water he saw half a month ago.

I came to the cooking workshop along the cement road, and the cooking workshop did not make much changes, except that the firewood used for cooking was replaced with coal, and coal gangue was used.

The cooking material is to slowly boil the raw materials into pulp, and the coal gangue with low thermal efficiency is enough, and the use of these coal gangue transported by water greatly saves costs.

Leave the cooking workshop with its steaming and pungent smell.

Zhu Shun, Zhang Baiyong and others came to the washing workshop, and the improvement plan of the washing workshop was to use the water flow to carry out strong washing of the pulp according to the washing method of the coal washing plant.

The cleanliness of the pulp is much cleaner than that of the craftsmen, and the time taken is greatly reduced, and the number of washes out at one time is not comparable to that of the bureaucratic squire's workshop.

The next step is the all-important whitening, in which Zhang Baiyong adds a certain amount of sulfuric acid to turn the natural pulp into white pulp.

The traditional whitening method is to turn the washed pulp white through the sun's irradiation, which lasts for two or three months, and the pulp washed by sulfuric acid is greatly reduced in whitening time, which greatly accelerates the time of paper production in the paper mill.

There are four workshops of foaming, boiling, washing and whitening, only the washing workshop slightly uses the power of the steam engine, and the next few papermaking factory workshops use a large number of steam machinery.

Before Zhu Shun walked out of the whitening field, he had already heard the sound of the steam machinery 'rumbling', and at the same time, there was also the sound of the steam machinery pounding pulp.

When he came to the beating workshop, there was a wooden barrel in front of Zhu Shun, and there was a steam ramming machine behind the wooden barrel.

Workers put the pounded pulp and paste on a conveyor belt and transport it to the papermaking workshop, where they pour the pulp into the papermaking tank.

The papermaking trough in the papermaking workshop was much larger than that in the bureaucratic squire's workshop, and the papermaking trough the size of a water tank was enlarged to the size of a pool.

There is a large bamboo curtain in the papermaking trough, and a steam lifting salvage machine slowly lifts the bamboo curtain under the operation of the workers.

A thin layer of wet paper sheets is formed on a large bamboo curtain and moved to the pile of paper next to the paper making trough.

There is also a steam pressurizer next to the paper trough, and when the number of wet sheets accumulates to dozens of dollars, workers in the paper factory operate the steam lift pressurizer to slowly pressurize the wet paper pile.

The water in the wet paper pile flows out slowly, and the water pressed out should not be too much and should not be too little, too much will be exposed when the paper is divided, and too little will be easy to fall off when the paper is baked in the last step.

The last step in the bureaucratic squire's papermaking workshop is to bake paper, which consumes the most firewood and is the reason why the cost of paper production increases considerably.

Paper mills have no such concerns, as the excess heat generated during the operation of several steam engines is piped to the baking shop.

There are large bookshelves in the baking paper workshop, and the iron bookshelves are all hollow, connected to small iron pipes, and infusion of high-heat steam.

The craftsmen placed the wet pages on iron bookshelves, laid them out one by one, and used the excess steam heat of the steam engine to bake the paper for the final purpose.

Although it is already the season of stinging, and there is only half a month left before the spring equinox, the winter of Daming is still quite cold.

The whole paper baking workshop steamed out a lot of white gas in the cold winter, it looked like the clouds and mountains were covered with fog, Zhu Shun walked in as if he had stepped into a hot spring full of fog, his body was very warm, and there were craftsmen in front of him who couldn't see three steps away from the white fog.

Everything looks like a wonderland.

It is believed that it will not be long before the baking workshop where snow-white paper is made will be regarded as a real wonderland.

Zhu Shun walked out of the baking workshop and walked all the way to the door of the paper factory.

Look around.

The cooking workshop and baking paper workshop are gushing with steam covered by clouds and mountains, and all kinds of steam machinery are rumbling, a noisy scene of the steam age.

Zhu Shun is very satisfied with the paper factory led by Zhang Baiyong: "This matter has been done well, I thought it would be beyond the sting season, but I didn't expect it to be completed ahead of schedule." ”

"Ben Hou has already told the patent office about this, and the sulfuric acid bleaching method and these steam machinery will buy patents at the highest price."

"The all-pig banquet in the cheap shop has also been arranged, let's go, Benhou invites you to drink."

Zhang Baiyong heard the word "drinking" from the mouth of the mountain chief with his own ears, and before he drank it, he was already a little dizzy, and said with a red face: "Then the student is disrespectful." ”

Zhu Shun smiled, walked away from the paper factory, and decided to take out a pot of wine given by Chongzhen in order to reward Zhang Baiyong and Luo Mingtang for their contributions.

Not long after the all-pig banquet in the cheap shop went on, Zhu Shun commended Zhang Baiyong and Luo Mingtang for their merits and left here.

Zhu Shun, as the head of the mountain, was there, but the students of the Beijing Normal University Hall couldn't let go, and besides, this banquet was not for eating, but to give Zhang Baiyong Luo Mingtang and other students of the Beijing Normal University Hall a thing that they could brag about for a lifetime.

The mountain chief invited them to drink, and they drank the wine given by the emperor.
