The Richest Man Yang Fei - Chapter 694
Chapter 692 A major innovation in the history of lau
Regardless of the cause of this battle in the daily chemical industry, it has dragged on for two months. Such a long fierce battle is no longer something ordinary companies can afford.
Let alone small and medium enterprises, even Procter & Gamble and Unilever are miserable.
As Yang Fei said, after entering this circle, no one can jump out, and can only fight until they are defeated.
Yang Fei decided to use a new product launch conference to end this bitter battle that no one can benefit from.
April 1, 1996, this day, in the eyes of Westerners, is April Fool’s Day.
But for Chinese people, the coming of this day is the beginning of the Qingming Festival.
Before and after the Qingming Festival, there was a lot of rain. The first three days and the next three days were the days of going to the grave for sacrifice.
The willow tree on the side of the road has taken out its buds, and the green make-up becomes one tree high. The branch is folded and a ring is worn on the head. It has a special flavor.
On Yang Fei’s head, he wore such a wicker ring with some small wild flowers inserted into it.
This was made for him by Su Tong, saying that wearing it on his head would bring him good luck.
Today’s Yang Fei really needs a little good luck to support it.
The new product launch conference of Jiebai laundry detergent was grandly held in the lobby on the first floor of Meili Building, Wudaokou, Beijin.
A huge screen, hung in front of the stage, repeatedly showing a promotional film about the history of washing powder.
“It’s a month in Chang’an, and there are thousands of households smashing their clothes. The autumn wind is endless, it is always Yuguan love.”
This poem describes the laundry activities of the working people in ancient my country.
In ancient my country, working people often used a pounding pestle, also known as pounding anvil, which was made of wood, similar in shape to a baseball bat, and about 30 cm long. The force of the pounding pestle was used to bring out the dirt with water.
Therefore, washing clothes in ancient my country is called “pounding clothes”.
It is said that the pounding pestle was invented by people living near the water to facilitate laundry, while people living far away from the water invented the washboard.
Uh, the washboard arrives in later generations, is it said to have a brand new purpose? -Cannot be described here.
The most beautiful description of laundry is “Xishi Huansha”.
When the beautiful Shih Tzu wore her yarn by the river, Yuer saw her reflection and forgot to swim to the bottom of the river. Therefore, Shih Tzu was called “Shen Yu” and became one of the four greatest beauties in the history of our country.
Laundry is one of the most basic housework, and it was once the housework with the most physical exertion.
After 4,000 years of exploration and experimentation, mankind finally found a relaxing way to wash clothes. The washing machine is hailed as one of the 100 greatest inventions in history. It not only represents the wisdom of the modern industrial revolution, but also frees thousands of people from heavy housework.
The original clothing cleaning materials are when people accidentally discover that utensils stained with some substances are easier to clean during sacrifices or barbecue activities, and then search for the reasons and discover the mystery of cleaning clothing.
This magical substance is plant ash.
According to records, in 600 BC, when the Phoenicians mixed goat fat and plant ash to make soap, the Phoenicians discovered the superior properties of surfactants, that is, it can weaken the surface tension of water and make the water better. The ground penetrates the fabric, breaks down the dirt and lets it float to the surface, until it is finally washed off.
The working people in ancient my country also discovered that plant ash can be used as a detergent.
“Book of Rites · Nei Ze Pian” said: “The crown is dirty, and the ash is rinsed.” It means that the belt of the hat is dirty, and it is washed with the ashes of the vegetation.
This is because the potassium carbonate in plant ash can remove oil stains.
According to the records of Kaogongji, in order to make silk silk soft and white, the ancients moistened the silk silk with plant ash water and put it in the ashes made from shells. The ancients called it a “mirage” and soaked it with water.
This is because plant ash water and shell ash can react to produce a strong alkali-potassium hydroxide.
Generally, the dirty substances on clothes are mainly oils, and most of the oils are fats. Under alkaline conditions, the degree of hydrolysis is intensified, producing higher fatty acid salts and glycerin that are easily soluble in water.
The main component of plant ash is strong alkali and weak acid salt, and its aqueous solution becomes alkaline due to the hydrolysis of carbonate ions.
During this period, in addition to plant ash, people also used animal oils, vegetable oils, saponins, and alkali salts to wash clothes.
In the Han Dynasty, people already knew that trona was used to wash clothes.
In the Jin Dynasty, people added starch and spices to the caustic soda and sold them in the form of ingots.
At the end of the Ming Dynasty, Beijing had shops specializing in the sale of artificial fragrance. Among them, “Hexianglou” and “Huahanchong” were still selling boxed peach-shaped and gourd-shaped rosaceine until the 1940s and 1950s.
What happened to the “Yanzi” that the older generations said?
During the Northern and Southern Dynasties, Jia Sixie had already mentioned the use of pig pancreas for descaling.
There is a formula in the “Thousand Gold Prescriptions” written by Sun Simiao, the “medicine sage” of the Tang Dynasty: Washed pork pancreas is ground into powder, and bean powder and spices are added to make granules.
This is the ancient pancreas, also called bath beans.
Later, people combined the pancreas seeds and aromatine together to make glutinous rice balls, such as sweet-scented osmanthus pancreas and rose pancreas.
With surfactants such as water and plant ash, people’s clothes are washed much cleaner.
But whether you use a pounding pestle or rubbing with your hands, washing clothes is very hard.
Is there a way to save effort?
Have.
When sailing in the sea, the sailors are very labor-saving to wash clothes. They put the dirty clothes into a cloth bag and tie one end of the rope to the boat. The cloth bag is thrown into the sea. During the voyage, the sea water is stirred and slapped on the clothes and clothes. Just wash it.
Inspired by the “sea washing”, someone invented a washing device in 1677, which uses a device composed of wheels and cylinders to squeeze the flow of water to imitate the effect of sea washing.
This device is the prototype of modern laundry machinery.
The washing machine is hailed as one of the 100 greatest inventions in history.
Its greatness not only represents the wisdom of the modern industrial revolution, but also frees thousands of people from heavy housework. UU Reading www.uukanshu.com. com has become an indispensable necessities of life for people.
The promo stopped here abruptly and continued to be played repeatedly.
At the scene, in order to have a more intuitive performance effect, Yang Fei ordered several washing machines to be placed and demonstrated on the spot.
Laundry is a bland thing in life. Among the products used for laundry washing, washing powder has always occupied a major position.
However, people who are attentive will find that the washing powder cannot be completely dissolved during use, and the residue is likely to cause damage to the clothes, and it is not easy to rinse.
The main component of laundry detergent is non-ionic surfactant, which has strong decontamination ability, and can penetrate into the interior of clothing fibers to play a washing effect, and decontamination is more thorough.
Moreover, no matter how high-quality washing powder is, it will hurt your hands more or less.
This is because traditional washing powders and soaps use anionic surfactants, mainly sodium alkyl sulfonate and sodium stearate, which are relatively alkaline. The pH of the washing powder is generally greater than 12, and when used Great irritation and damage to the skin.
The beauty group launched this time is a brand-new product that is completely different from traditional laundry detergent-laundry detergent!
Laundry liquids mostly use non-ionic surfactants, which have a pH close to neutral and are gentle on the skin. After being discharged into nature, they degrade faster than washing powders. It can be completely dissolved and has a fast dissolution rate, easy to rinse and wash, and will not damage the skin and clothing.
With the slogan written by Yang Fei: “This is a brand new detergent, the greatest new invention in the history of laundry. The laundry revolution in the entire world will be refreshed today!”
Countless media and reporters in the audience have witnessed the birth of this miracle.
Can this brand new product end the industry war? Can Yang Fei and Meili Daily Chemical take it to a new level?
Yang Fei has high hopes for this, everyone will wait and see!
