The principle of breaking off heat is that when a supersaturated solution of sodium acetate forms crystals, it releases heat.
This crystal is called sodium acetate trihydrate, also known as "hot ice".
Because the crystallization process is reversible, when the heat used to form the crystal is dissipated and the crystal is heated, it can be reused.
Last night, Shen Qingqian improved the common heat-breaking method so that it can be heated quickly after the heat dissipation is completed, thereby forming crystals again to continue heat dissipation.
It sounds complicated, but it is not difficult for Shen Qingqian. As long as there are enough materials, there is no problem in making any amount.
Shengze, Yuan Lai, and Jun Yichen didn't come over for breakfast today. When they came, all the women of the Shen family were in the house.
After greeting everyone, Shengze and others looked at them curiously.
"What are you doing?" Yuan Lai came forward and saw the women of the Shen family sewing something.
Shen Qingqian smiled at Shengze, lowered her head and stuffed each bag with something, and casually answered Yuan Lai's question, "For winter."
Mrs. Liang picked up the finished product and handed it over, "Come on, take a look. We have this thing this winter. Our hands and feet will definitely not be frozen."
She even thought, if she could sew a larger skin bag out of animal skins, could she tie it to the outside of her inner clothes and put on her coat, so wouldn't she be protected from the cold?
Yuan Lai played with it curiously, and after a moment his eyes lit up, "Hey, this thing is pretty good!"
"Mr. Yuan, it doesn't matter if it generates heat. The key is that it can still generate heat after it cools down!" Mrs. Lin added with a smile.
Shen Qingqian made an excuse to move materials from the cellar of the sugar factory. The Shen family didn't suspect anything. They just did what she told them to do. So far, no one knows what they put in their bags.
Yuan Lai became interested, "So magical? Then I have to take a closer look."
He took the things and went to the house, intending to study them carefully.
Shengze was thinking about what he had remembered last night, so he went to Shen Qingqian and whispered, "Sixth sister, I have something to tell you."
When Shen Qingqian heard this, she looked up and saw a trace of distress in his eyes. Her original refusal turned into, "Okay, you go to the next room and wait for me."
After saying that, she turned to Shen Qingman and said, "Second sister, these two things are very important. Don't forget to stuff them into these bags."
What she is doing is stuffing condensation nuclei and her improved things into the skin bag. If there are no condensation nuclei, the heat will not heat up, but it is very important.
"Okay, don't worry when I do the work. Go, go, go." Shen Qingman covered his mouth and smiled, and looked at Shengze again.
The sixth sister must not know that her behavior when facing Shengze is different from other people of the opposite sex.
She didn't know why before, but now she completely understands it. Being young is good!
Shen Qingman may have forgotten that she is only a few years older than Shen Qingqian.
Shen Qingqian told them to get over it, but found that Sheng Ze and Jun Yichen were both there.
She was a little surprised, "Do you two have something big to tell me?"
"Miss Six." Jun Yichen stood up to greet her.
Shen Qingqian quickly returned the gift, "Young Master Jun, you don't have to be like this, it's better to be more comfortable."
This Jun Yichen is really cold and cold in the past, but now he is gradually changing. I don't know what kind of person he is.
"Qianqian, I want to ask you to help me look at something. Have you seen this thing before?" Shengze took the mirror out of his arms and handed it to her, with expectation in his eyes.
Shen Qingqian took it and took a look, "This mirror looks good...wait a minute!"
"What's wrong?" Sheng Ze was attracted by the exclamation behind her and immediately leaned over, almost head to head with Shen Qingqian.
