Chapter 117 When good things happen, I think of my father-in-law
“Liao Ke, no red rust will appear in the 960-hour salt spray test. This is the standard I set according to the more conservative requirements.”
“In fact, if Dacromet surface treatment is carried out strictly in accordance with the process, then there will be no problem if red rust does not appear after the 1,200-hour salt spray test.”
Jiang Hui looked at Liao Chengwen, He gave his opinion with firm eyes.
At this moment, Liao Chengwen was immediately silenced.
Today's electro-galvanizing will show some red rust after a 240-hour salt spray test.
Results Jiang Hui said that the Dacromet surface treatment process can prevent the parts from showing red rust after 1,200 hours of salt spray testing.
Technical people know this gap very well, and it is beyond imagination.
This is just like you are still using bronze to make weapons, while others are already using special steel to produce various swords.
It is completely a technology with generational differences.
"Xiao Jiang, can you briefly introduce Dacromet surface treatment technology?"
Ask if you don't understand. Although Liao Chengwen still doubts the authenticity of what Jiang Hui said, he is still willing to listen.
If there is such an awesome surface treatment technology, it will definitely be a big thing for China's industrial industry.
This can not only solve the corrosion resistance problem of wheel bolts, but also solve the corrosion resistance problem of many metals.
Once popularized, the economic benefits generated by the steel saved every year will definitely be measured in hundreds of millions.
Even the value it creates cannot be measured in terms of money.
“Dacromet surface treatment can achieve such a good corrosion resistance effect, which is closely related to its anti-corrosion mechanism.”
“I use Dacromet coating on steel substrates Taking the protective role as an example, let’s summarize the relevant situation.”
Jiang Hui knew that if he didn’t explain the situation clearly today, Liao Chengwen would not give up.
After all, the anti-corrosion effect I mentioned is really amazing in the eyes of people of this era.
Historically, China only introduced Dacromet technology in the 1990s, and now the use rights throughout Asia are monopolized by Japanese companies.
“As mentioned just now, Dacromet coating solution includes metal powder, solvent, passivator and special organic matter.”
“After treatment, Dacromet coating solution The layer will produce a barrier effect. This is due to the overlapping of the flake zinc and aluminum layers, which hinders the process of corrosive media such as water and oxygen reaching the substrate, and can act as an isolation shielding effect."
"Furthermore. It is during the Dacromet treatment that chromic acid reacts chemically with zinc, aluminum powder and base metal to form a dense passivation film, which has good corrosion resistance. ”
"Finally, the main protective function of the zinc-aluminum-chromium coating is the same as that of the galvanized layer, which is cathodic protection of the substrate. It can provide a protective effect many times better than that of electro-galvanizing."
"After the above three functions are superimposed, the effect is extraordinary."
Jiang Hui quickly explained the anti-corrosion mechanism of Dacromet surface treatment, at least letting Liao Chengwen know from the theory Judging from the above, this exaggerated surface treatment technology can exist.
“Since the benefits of Dacromet surface treatment technology are so great, is it possible for us to develop this technology?”
Liao Chengwen felt a little guilty when he said this. Yes, because after listening to Jiang Hui's words, he had no clue about implementing Dacromet surface treatment technology.
In the end, this situation will definitely depend on Jiang Hui’s performance.
"Of course we have to get it out, but some coating and processing process parameters need to be confirmed during the research and development process."
"The conditions of our factory are not particularly perfect in this regard. I will sort out the situation and talk to the Capital Institute of Technology to see if I can help them decide on a plan for this surface treatment technology.”
When good things happen, you must think of your husband. people. Dacromet surface treatment technology seems very inconspicuous, and 99.99% of people have never heard of this technology.
But once it is promoted in China, the economic significance will be extraordinary.
If Zhu Jiansheng can take the credit for this, it may have unexpected effects in his future career development.
4MT manual transmission, "Hummer" project, Dacromet surface treatment technology...
Major achievements one after another can definitely push Zhu Jiansheng to continue to move forward.
Even if the father-in-law is unwilling, Jiang Hui is ready to give him a hard push!
“Okay, since you have already made arrangements, I’m relieved.”
"But time waits for no one. The Dacromet surface treatment process must be finalized as soon as possible, otherwise we may not be able to catch up with the prototype truck loading."
After a few words of warning, Liao Chengwen left Jiang. Hui's office.
Thinking that he and Chen Chenxing would go to the Japanese Embassy to repair the car this weekend, Jiang Hui directly picked up the phone and planned to ask Zhu Jiansheng to get things started first.
Capital Institute of Technology has materials-related majors, and their laboratory has the conditions to make the coatings needed for Dacromet surface treatment.
Some other majors such as vehicle engineering have also conducted research on surface treatment technology.
Jiang Hui left the project to Zhu Jiansheng to take the lead. Jiang Hui felt that the problem was not that big.
Anyway, I know the complete process flow and coating requirements of the Dacromet surface treatment process. At worst, I will let the other party generate it directly based on the results.
First figure out whether there is any problem, and then figure out why each parameter should be set like that.
"Dad, it's me."
After wasting more than ten minutes, Jiang Hui finally got through the phone number of Zhu Jiansheng's office.
As the acting director of the Department of Vehicle Engineering, Zhu Jiansheng also has his own independent office.
"Xiao Jiang, what's wrong? What happened?"
Zhu Jiansheng's tone was obviously a little nervous.
Since going to work at the Capital Automobile Manufacturing Factory, Jiang Hui has hardly called Zhu Jiansheng during working hours.
Now that a phone call suddenly came over, it was normal for Zhu Jiansheng to be nervous.
"Dad, there is a project that I need your help organizing..."
Jiang Hui quickly told Liao Chengwen that he went to Chaoyang Fastener Factory today to confirm the new BJ212 wheel bolts, and then mentioned Here comes the Dacromet surface treatment process.
After spending more than ten minutes, Jiang Hui briefly sorted out the Dacromet surface treatment process and gave Zhu Jiansheng a basic concept.
Zhu Jiansheng also recorded the key coating materials and precautions in the surface treatment process with a pen.
“If this Dacromet surface treatment technology is really that good, the significance will definitely be huge.”
"I will compile a report immediately and send it to the college to coordinate with several other departments to research this technology."
Zhu Jiansheng knew that his son-in-law was giving himself credit again.
But this is not the time to be humble. Hurry up and put things into practice first.
