The area is 166.25 square centimeters. The mask weighs about 3.098g, the ex-factory price is 0.3 yuan, and the cost price is 0.22 yuan. This price surprised us, because the price in the market has increased by nearly 10 times, especially during the epidemic.
The mask production equipment consists of a discharging mechanism and a folding mechanism.
Ear wire discharge mechanism, flanging mechanism, ultrasonic welding mechanism
Mask cutting mechanism and mask distributing mechanism
Ultrasonic welding ear wire mechanism
Mask forming and stacking mechanism, control system, etc.
Such a complete set of equipment
The current price is about 65438+ ten thousand.
However, during the epidemic, more than 400,000 masks produced were sent to the disinfection room.
Introduce ethylene oxide gas for disinfection.
Finally, we must analyze the toxins.
Until the residual amount of ethylene oxide on the surface of the mask reaches the standard.

And put it into such a large-scale production workshop
Need to invest 3-4 million.
However, the cost was recovered through the production and sales of 10 days before.
We have to feel that demand exceeds supply.

Let's answer the question
This time, Mr. Jin, the math teacher, gave us 20 questions. Watch what I do! I thought over each question carefully and then began to answer it. After the teacher handed out the answer, I checked it and found a wrong question. The title is shown in the picture. I think it is too complicated. I don't think I can buy five every time I go out, so there are three possibilities.

Learning summary
Through these activities, I learned a lot about masks and consolidated my math knowledge. This is really a meaningful activity, which not only enriches my summer vacation life, but also can learn something that I can't learn in textbooks. I am also quite satisfied with my performance in this research.
