I, go to the parent-teacher meeting for my eldest niece!

Scientific research is not as profound as everyone thinks, and it is not unattainable.

Scientific research is based on high school knowledge, and then flexibly applied according to the object of research.

Although college also learns some knowledge, except for calculus and linear algebra, college knowledge is inextricably linked to high school knowledge.

Therefore, an excellent high school student, there is absolutely no problem in engaging in scientific research.

Wang Yi can get a full score of 750 in the college entrance examination, and he is still a prodigy with a system, and it is no problem to engage in scientific research.

At this moment, after reading all the information, Wang Yi had become a big man in the field of polymers, walked in front of Wang Wenying, and said:

“Big sister, what you did is a PLA experiment, PLA has a wide range of sources, low cost, easy processing, and has excellent biocompatibility, degradability and low biotoxicity, which can be used for welding and sedimentation molding 3D printing technology.”

PLA forms polymer fibers at around 175 degrees Celsius, and can be 3D printed by calendering between 200 and 230 degrees Celsius.

However, compared with common general-purpose plastics, PLA has the disadvantages of brittleness and low composite strength, and if applied in the medical field, its degradation product lactic acid will cause tissue inflammation and cell necrosis.

Big sister, if you want this experiment to succeed, you must improve the resilience of PLA itself. ”

Wang Yi is like a scientific research boss, describing the characteristics of the materials made by Wang Wenying, and pointing out the problem of Wang Wenying’s experimental failure.

Wang Wenying was still crying because the experiment failed again, but when he heard Wang Yi’s words, he was shocked.

Wang Yi’s simple words summarized all the characteristics of polylactic acid PLA, even if he is an entrepreneur who has been engaged in polymer research and development for many years.

And Wang Yi also pointed out the direction of success in the last sentence, which shocked Wang Wenying even more.

“To improve the resilience of PLA itself, how to improve this?”

Wang Wenying looked at Wang Yi in disbelief, her eyes full of incredulity.

“Big sister, you have been tired for several days, let’s rest for a while, and I will do the next experiment.”

Wang Yi knew that he had gained Wang Wenying’s trust and could now officially help Wang Wenying.

“You’ll do it?”

Wang Wenying didn’t react for a while, and couldn’t believe that his little brother, who had always needed his own care and protection, would actually cover himself from the wind and rain one day.

“Mom, you don’t want to ink anymore, hurry up and let your uncle do it!”

Although Zhang Qianqian cleaned for a night and was already tired and collapsed, when she heard that Wang Yi was going to do an experiment, she immediately became excited again, pulled Wang Wenying aside, and watched Wang Yi do the experiment as excitedly as if watching a play.

Wang Wenying still seems to be in a dream at the moment, and feels that this reality is too unreal.

Zhang Qianqian is full of confidence in Wang Yi, can take the third (16th) class of high school to stab to death the sharp knife class, can make her, the penultimate candidate Hua Qing, what else can’t Wang Yi do?

“Big sister, is there any wheat straw powder? I need to use it as an enhancer. ”

Wang Yi walked to the test bench and asked Wang Wenying.

“Oh, yes, I’ll get it for you right away!”

“I also need aminopropyltriethoxysilane coupling agent, maleic anhydride grafted polypropylene compatibilizer, polyethylene wax lubricant to assist the experiment.”

“Okay, I’ll bring it to you too!”

Although Wang Wenying didn’t know what Wang Yi wanted to do, Wang Yi said it too professionally, and she was shocked by Wang Yi’s temperament as a scientific research boss, which can crush Chen Zhijun for dozens of streets.

Wang Wenying hurriedly handed all the materials to Wang Yi.

“Next, I will use polylactic acid PLA as the matrix and wheat straw powder as the reinforcement to prepare wood-plastic composites for 3D printing by fused deposition molding by extrusion molding process…”

While speaking, Wang Yi operated at the same time.

Hearing Wang Yi’s such a professional term, Wang Wenying’s whole person was stunned, he didn’t have the professional Wang Yi said, did Wang Yi really only learn polymer for a while?

“Xiao Yi, what equipment do you need?”

Wang Wenying decided to be Wang Yi’s assistant, and whether Wang Yi succeeded or not, she would support Wang Yi immensely.

But if it succeeds, all the better.

“I need a high-speed mixer, a two-stage plastic extruder unit, a high-precision 3D printing consumables extrusion testing machine, a 3D printer, an electronic universal testing machine, and a combined impact testing machine.”

“These equipment companies have it!”

Wang Wenying couldn’t believe it was an 8-year-old child.

But Wang Yi can easily step on the college entrance examination, what else can’t he do?

When everything was ready, Wang Yi began his experiment.

Wang Yi first modified and dried the wheat straw powder, and then mixed all the materials evenly in the high-speed mixer, and added the mixed materials to the double-stage plastic extruder for melt extrusion to obtain the molten material, and after the molten material cooled, it was added to the crusher for crushing to obtain relatively fine pellets.

This set of experiments took two hours, and after two hours, Wang Yi produced a batch of 3D printing materials.

But it’s just produced, and after it is produced, it needs to be inspected.

Inspection is the only truth of scientific research, and only scientific research products that can withstand the test can obtain a broad market.

However, even if there is no inspection, Wang Wenying is also pleased to see that Wang Yi can produce this batch of 3D printing materials.

Glancing at the time, it was already 12 o’clock at night, Wang Wenying felt sorry for his little brother and said:

“Xiao Yi, it’s not early, let’s get here today, and we’ll do the experiment tomorrow!”

The reason why Wang Wenying said this is not only because he feels sorry for Wang Yi, but also because he is afraid of failing again.

Wang Wenying has experienced many failures, and her spirit has collapsed to the edge, if she fails again, then she really can’t bear it.

3D printing material Wang Wenying can also be produced, but she developed it, but the material performance she developed is too poor, on the 3D printing equipment, the printed items are directly broken, just like her heartbreak, there is no need for later detection.

Wang Yi has reached the last step before Wang Wenying’s failure, and at this moment Wang Wenying has developed a sense of fear.

Wang Yi became her last hope, and she didn’t want to be disappointed again, so she wanted to postpone this disappointment until tomorrow.

“Today you have to experiment successfully, tomorrow you have to mass-produce it, and you want to get all the products ready by the deadline for the order.”
