Since you want to kill insects, you must be thorough.

Wang Yi spared no expense to purchase Bayer's insect-killing medicine, which used cyanthrin as the main body to spray and kill a variety of ectoparasites.

This thing is a broad-spectrum insect-killing medicine, and the medicine is very effective!

Cyclomethrin is a magical medicine for killing pests. It can be used to kill pests and is also toxic to stomach. Whether the pests are touched or eaten, they will die.

Death is very happy—

Cyclothrin can stimulate the nervous system of pests, causing them to die of excessive excitement.

Simply put, they are terrible.

Wang Yi chose this spray because it uses SC suspension technology, which can adhere well to the surface and even around the spray, which is not easy to decompose, retain for a long time, and is not easy to evaporate.

However, it is three parts toxic. Pesticides are definitely more or less toxic to the human body. The advantage of cyanthrin is that they are low in toxicity to the human body. If they are used moderately in 1982, they will not cause toxin enrichment problems, so it is quite safe.

There are many rats on the island, so you have to buy rat poison.

In fact, the living conditions of the people in the team are better now, so it is good to raise some cats to kill rats in life, but unfortunately the island is not suitable for raising cats.

The mountaintops on Tianya Island are quite large. After the cats come to the island, they don’t know how to catch mice but they do.

Moreover, there are many people in the team who raise chickens now, and they are worried that cats will hurt chickens, so this can only be an idea. In the production team, the freedom to pet cats cannot be realized.

He roughly purchased some materials and sent the materials to Dunzi. These materials had to be packaged by the island production team before they could be landed on Tianya Island for 1982 years.

Qiu Danian also sent him a message, including a technical introduction to the brick kiln factory using seawater to burn bricks.

After all, it is best to use clay and red clay to burn bricks. However, as long as it is qualified soil, you can burn bricks, but the characteristics of the bricks will be slightly different.

During the firing process, the addition of salt should be avoided, because the salt dissolves after it is exposed to water and is used to burn into a brick, and then it will be brought to the surface of the brick through the microporous structure.

In this way, as the water evaporates, the salt will be deposited, forming a white powdery frost layer. This is professionally called frost, which is also what ordinary people often call brick white frost.

To be professional, frost is a salting phenomenon caused by soluble salts on the surface of bricks. Generally, white powder will form clusters of spots on the surface of bricks.

If this type of brick is used in wet parts of the building, the internal porosity of the brick will increase due to the dissolution of the salts incorporated into the brick.

Another salting process on the surface of the brick will crystallize, which will cause the surface components of the brick to expand and loosen, and eventually cause the surface of the brick to pulverize. Simply put, the brick will not be strong.

The four seasons of Tianya Island are not particularly distinct, and the temperature difference between summer and winter is not very large. The problem of using frosted bricks is not too big. If you use frosted bricks in areas such as Northeast China with large temperature difference between winter and summer, something big will happen:

Thermal expansion and contraction are the basic physical laws, and coupled with the poor performance of frosted bricks, this has a great impact on building safety.

Places like Tianya Island or Jiangnan Province are not very different in temperature, which will not cause major problems with the characteristics of bricks, but construction sites will still not use frosted bricks.

After all, the main purpose of building tiles on construction sites is to build buildings. Building buildings requires the use of a lot of steel. The salt in the frosted bricks will corrode the steel and create safety accidents.

What if it was a bungalow built in a rural area?

Not much is used, and these are mainly considered in two aspects: on the one hand, it is not beautiful, and on the other hand, the loose surface of the brick will destroy the bond between the brick and the applied mud and cement.

So is there a way to solve the problem of frosted bricks caused by seawater brick making?

Can't solve it.

However, after modern architectural science research, some new technologies can reduce the salting rate of frosted bricks, which is equivalent to extending the life of the bricks.

These techniques include physical methods and chemical methods.

The physical method is to build a new cave and appropriately extend the roasting time, which can promote the reaction of silicate minerals and alkaline oxides, thereby reducing the formation of salt and achieving the purpose of reducing frost.

There are many chemical methods, such as adding new alkaline oxides during the firing process to minimize the formation of salt and promote the discharge of salt minerals.

For example, if you use hydrochloric acid removal method to treat the bricks after the kiln, that is, spraying the bricks with 2% hydrochloric acid can also reduce the precipitation speed.

The most effective is a silicone waterproof coating removal method!

Qiu Dainian spent money to consult experts from the Jiangnan Provincial Architecture Research Institute, and the experts introduced him to a silicone waterproof coating.

This coating is made of imported silicone as the main raw material and emulsified through an advanced process. After spraying or painting on the surface of the brick, it can penetrate into the brick for several millimeters, forming a film that is invisible to the naked eye.

Therefore, even if there is soluble salt in the brick, it cannot penetrate to the surface of the brick!

As long as the salt in the brick cannot be precipitated, it doesn’t matter whether there is salt or not for the bungalow, it doesn’t affect the hardness and life of the brick anyway.

Wang Yi looked through it with interest and found that the construction method of this silicone waterproof coating is also very simple. First, clean the brick surface, and then use silicone waterproof coating to add water to prepare - this time you have to use light water.

During the process of burning bricks, sea water can be used to mix the soil, but when making silicone waterproof coating, you must use light water, then mix well and then spray directly with a sprayer.

Generally, it must be sprayed twice, and then sprayed the second time after the first time solidifies.

This thing is like waterproofing in the decoration of a building. After two silicone waterproof coatings, the salt inside the brick cannot be parsed out and cannot have an impact on the bricks.

Now this technology has applied for patents and is being promoted to the market, but the market application prospects are not very good.

Why?

High price!

Originally, red bricks are not expensive, for example, the market conditions this year are relatively poor. The ex-factory price of red bricks in Jiangnan cannot be used for 50 cents. The cost and labor of this silicone waterproof coating are high. On average, it has to add a 20 cents to a brick.

Considering the huge demand for red bricks in buildings, the cost is a lot!

However, the reason why the Provincial Architectural Research Institute studies this technology and introduces related silicone waterproof coating formulas is not that the leaders and mentors are looking for projects to earn extra money for themselves, but that they want to use the sea mud!

The coastline of Jiangnan Province is long, with rivers entering the sea estuaries in many places, and even the Shanghai next to it has the sea estuaries in the Yangtze River.

As we all know, rivers flow into the sea will carry a large amount of silt, causing silt at the estuary. In order to ensure the normal operation of waters, rivers, ocean shipping, flooding, etc., all provinces and cities will carry out dredging work every year.

This work has been carried out since ancient times and has to be carried out in 1982. Sometimes members chat together and say that Shanghai workers are actually working on dredging for the sea estuary!

The inland production teams also have to go to work when the farm is not busy in winter. They are dredging rivers, while the out-of-the-island production teams are dredging the sea estuaries. The inland and the seaside farmers work together to ensure the basic operation of the national water conservancy work!

For example, the Wang family production team on Tianya Island this winter must send laborers to clean up the dredging and clear out the mud and sand.

It is still unclear how much mud should be cleared. According to the information, after the 21st century, local governments began to use dredging ships to clear the silt at the sea estuary, with the annual mud discharge reaching 1.7 million tons, and these silt can be used to produce 1 billion bricks!

The provincial construction research institute wants to use this silt for waste, and it has been successfully utilized.

Bricks made of silt are called sea mud bricks. There is a PPT in the electronic information that specifically introduces sea mud bricks.

Wang Yi opened it and looked at it roughly. These sea mud bricks were light pink, and their weight and strength were the same as those used in the past to build houses. It was more than enough to build bungalows in rural areas.

In this way, after reading the information, he couldn't help but slap his thighs excitedly!

OK, the technology is in place.

He called Qiu Danian directly and said, "Mr. Nian, you made a contribution to me this time, and the bonus in the third quarter will double!"

Qiu Danian said embarrassedly: "The boss is quite simple. You can get an expert to spend some consultation fees. This way I will add a bonus, which makes me quite a bit - mainly because you don't know my bonus in the third quarter?"

His and Dunzi's bonus is mainly related to the production team's big stove and the sale of some old items on weekdays, such as old newspapers and magazines, old stamps, and scattered first and second editions of RMB.

Wang Yi checked the relevant sales, and naturally remembered the bonus amount of the two of them, and said, "The bonus on your side is about 180,000. Of course I know. If I don't even understand the company's accounts, what kind of boss will I be for you?"

Qiu Danian smiled and said, "It's more than 180,000, 200,000. Boss, you haven't checked the accounts recently. Last time you sent a batch of hairy crabs, which were sold very well. This one has to be considered a bonus."

Wang Yi said: "Oh yes, I haven't read the bills these days, so you can send me the electronic bills. I'll check the electronic bills first and then hold a meeting for you to discuss financial issues in detail."

He must hurry up in financial work.

He was not stingy about giving Qiu Danian and Dunzi some money, but he was afraid that the two of them would be crazy and would make trouble with him on his back.

Now, everything is fine.

Dunzi is a man who is loyal and loyal. He doesn't value money very much, so last time they accompanied Qiu Danian to meet his family with him, they each received a bonus of 100,000 yuan. Dunzi directly gave Qiu Danian 100,000 yuan-

It was not borrowing, but it was given directly to Qiu Danian, so that Qiu Danian could be more face-saving when showing off his deposit in front of his family.

Qiu Danian's character is also trustworthy. At least Wang Yi can't find any problems every time he checks the accounts.

You should know that Qiu Dainian is very good at living. He has always had the habit of keeping accounts. He has two book books on his mobile phone. Even if he spends one dollar to buy two small puddings on his daily basis, he has to keep them on his bill.

Therefore, the company's bills are very complicated but clear, and every income and every expense has detailed records.

In addition, if the accounting is carried out through the online merchant platform, there will be a transaction certificate from the online merchant platform at that time.

Qiu Danian reported to Wang Yi on the phone, and reported the production team's recent turnover and hairy crab sales.

Wang Yi calculated that the third quarter bonus he paid Qiu Danian and Dunzi exceeded 200,000, plus the salary of the employees in the production team's stove and Tianyadao employees, the company's salary expenses this month exceeded 600,000.

In this way, he doubled the bonus for Qiu Danian.

Qiu Dainian did his best to help him work. This time, it was so important that he could quickly find the technology for producing sea mud bricks, and sea mud bricks were also so important to Tianya Island in 1982.

Originally, he planned to take mud and burn bricks from major islands, especially uninhabited islands. With information on sea mud bricks, he found that when winter started to work in Shanghai, the raw materials for burning bricks could really be continuously in full swing:

The team members said that the silt dug by Shanghai workers is useless because it contains salt halogen. The government treats it as garbage and spends money to pour it onto an uninhabited island.

In this way, Wang Yi pays some freight for the transport ship and collects the sea mud and burns bricks directly.

The local materials are collected and the freight is low, which instantly reduces the cost of sea mud bricks!

He excitedly gave Qiu Danian a bonus, and he instructed Qiu Danian to start purchasing silicone waterproof coatings.

This can be taken until 1982 without heavy packaging.

The silicone waterproof coatings are all made of black plastic barrels, and a label paper is on the outside to introduce product information. Just tear off the label paper.

In addition to the development arrangements in 1982, there are also some arrangements in 22 years. Wang Yi told Qiu Danian: "You hire a few experts, geology, agriculture, and production, and find some real experts anyway."

"Then you invite them to the outer islands and let them go around the various islands, especially some uninhabited islands around, to see if there are any projects that can be adapted to local conditions!"
