Chapter 315 I disagree! "Why do I feel like this helmet doesn't feel right? It's a lot lighter than before."
Upon hearing this, everyone subconsciously weighed the safety helmets in their hands.
"You know what, it really seems to have become a lot lighter!"
They used to go to the construction site frequently, and every time they came back, their necks were sore and painful.
They weren't used to it after only wearing it for a few hours.
It is conceivable how much those workers dislike wearing safety helmets.
At this time, some careful people discovered that the safety helmets they received were not only much lighter in weight.
The internal structure also seems to be different.
Each helmet has a cross-shaped suspension system made of canvas straps and rivets.
Seeing this, Chris complained to Chi Heng, "This helmet is so light, how can it really provide protection?"
Professor Xu happened to be standing nearby, and upon hearing this, he smiled and explained.
"Don't worry about safety. We've already done experiments before."
"Don't underestimate these canvas straps inside. If something hits the hat shell."
"This cross-suspension system provides excellent cushioning and is much more effective than simply adding a thicker helmet!"
When they heard that the test had been done and that an expert like Professor Xu had personally guaranteed it, everyone felt relieved and put on their safety helmets with a smile.
"Who came up with such a good idea?"
At this moment, several deans who were familiar with Professor Xu made a half-joking remark.
"Old man, you too, why didn't you tell us earlier?"
"We just got it not long ago." Professor Xiao said proudly, "This idea was thought up by Xiao Jiang!"
Upon hearing this, Chi Heng paused slightly.
"Xiao Jiang?" Which Xiao Jiang?
"Who else could it be, Little Jiang?" After coming to his senses, Professor Xiao pointed at Jiang Si who was not far away.
"Is this Engineer Jiang's idea?" Everyone was even more surprised.
"yes."
Seeing their faces full of disbelief, Professor Gu simply told them about what happened two months ago when Jiang Si came to him to discuss improving the safety helmet.
He only gave a general idea, and the specific details still had to be explained by Jiang Si.
At this time, everyone has put on their helmets.
Jiang Si took this opportunity to officially start her two-day visit.
It turned out that most of the people in the visiting group came with the intention of finding fault or just watching the fun.
Unexpectedly, as soon as we entered the door, everyone's attention was attracted by this inconspicuous safety helmet.
Seeing this, Jiang Si briefly explained her ideas for improvement.
In fact, the materials used to make rear helmets are basically high-density HDPE or ABS engineering plastics.
But in this era, the technical level and craftsmanship cannot reach that level.
So she thought of a way to improve it.
In fact, the method is very simple, which is to add some chopped cotton fiber or wood pulp fiber to the raw materials for making safety helmets.
Of course, these are not as good as the effect of glass wool.
It’s just that glass fiber is usually used in military industry and aerospace, and the raw materials are difficult to obtain.
As for the function of the cross-shaped buffer strap inside, Professor Li had already explained it just now, so Jiang Si did not waste everyone's time.
It just emphasizes that the improved safety helmet can maximize the personal safety of workers while ensuring comfort.
There were many foreign guests present that day, although they did not understand what Jiang Si said at the time.
But her confidence, composure, and unhurried professional attitude still amazed everyone.
Especially after listening to the translators' explanations, everyone looked at Jiang Si with a little more appreciation and admiration.
Chris didn't say anything, thinking about what she had just heard in the state-owned store.
Inadvertently, she glanced at Chi Heng beside her.
Chi Heng was facing sideways towards her at this time, and she couldn't see the expression on his face.
But she was sure that from the beginning until now, Chi Heng's eyes were always on Jiang Si.
Thinking of this, Chris's eyes looked at Jiang Si with a complicated look.
