"First of all, the white body is the cab that has just been welded. There are some considerations in terms of material selection. It is best to use double-sided galvanized plates. Ordinary steel plates have a low cost, but in the future, they will appear
The problem." Qin Zhenhua happily introduced it.
The first step is to choose steel plates with particular attention! When the country's car industry just started to rise, early cars were prone to rust, just to pay attention to cost, and even galvanized plates were unwilling to use.
"Then, the first step is to spray primer. Primer is the most important thing. It requires electrophoretic spraying in a dust-free workshop. I won't introduce it to you, otherwise it will be a waste of time." A simple spray paint
Qin Zhenhua can also speak very well.
"After spraying the primer, then the middle coating is followed. This middle coating is the last intermediate coating before applying the topcoat. The paint base content is between the primer and the topcoat, and the coating is bright and semi-luminous. At the same time,
It also has the effect of replacing putty." Qin Zhenhua said: "Here, I want to talk about putty. We used this putty frequently before. It is a paint with more color fillers used to fill the surface, which can improve the flatness of the surface of the workpiece.
, but at the same time, there are many side effects. Putty coating is prone to aging, cracking, falling off, and there are more internal pores after film formation, causing the topcoat to seep and affect the appearance. Therefore, this process is no longer needed in advanced spraying processes.
Of course, this requires that the original flatness of our body surface is very high, that is, it needs to be guaranteed through our advanced stamping equipment and molds."
These words made everyone stunned. After all, so far, many people have not been to the first machine factory or seen the first machine factory manufacturing equipment.
The first machine factory has everything, and it has been waiting for a long time to produce it. It also has to cooperate with the Germans and spend hundreds of millions. What is the purpose? It is this world-class technology!
"The last one is the topcoat. After we spray this topcoat, we have to go through the paint step." Qin Zhenhua said: "Our paint technology, brightness, wear resistance and corrosion resistance are incomparable to spray paint. After these
After the process, it can be used normally and ensure that it will not fade for ten years."
What?
The things Qin Zhenhua said are quite mysterious. Unless it involves related majors, you won’t understand them at all. But now, when it comes to this conclusion, everyone has heard it clearly.
It has not faded for ten years!
"Even if our cars used good paint, they would fade in two years as soon as the sun was sunny and wind and rain were blown, and they would fade in two years, lose paint in three years, and rust in five years. This was the norm. I thought it was a paint problem,
I didn’t expect that there were so many things in it.”
"Yes, I only realize now that we are watching the sky from a well." After Qin Zhenhua said this, many people present started to talk.
That’s right, everyone was shocked, and it didn’t fade for ten years. What’s the concept? As long as there is no wiping or paint loss, then you won’t have to worry about it within ten years!
Especially for the troops, the troops' cars must be in the best condition. It can be seen that every time the troops' cars are used up, they are washed very clean, and even the chassis is not covered with dirt.
After all, if one of the screws rust and breaks, the car may have problems. If there is a problem on the battlefield, it is absolutely not allowed and it is a crime.
If the surface is always smooth, then it is easy to see various possible problems.
"Can the heavy trucks of the first machine factory do this?" asked an army leader on the rostrum.
"Yes, we use Mercedes-Benz technology." Qin Zhenhua said with a smile.
That’s right, the Iron Horse Factory relied on its perseverance to create the Iron Horse brand heavy truck, which looks exactly the same as the Mercedes-Benz heavy truck. It’s just the appearance, what about the inside?
There are so many things to say about a simple cab spraying process! Only by using a complete set of world-class technology can we achieve this level. What about the Iron Horse Factory?
At this time, Liu Tiande had already reacted. Qin Zhenhua was here to promote their heavy trucks. In this way, even if the price of the one-machine factory products is more expensive, there is a reason for them to be expensive.
"What's the use of this? At worst, we can paint once every few years, and it's the same as new." Zheng Heping said there, and they could only refute this way.
Their heavy trucks, without this technology, aren't they just a cab? Is it necessary to do so much trouble?
However, it was a bit inappropriate to say this, and Liu Tiande frowned even more. Qin Zhenhua could fight back with just this sentence.
"Yes, this is the case with our previous craftsmanship. At worst, we can paint every few years." Qin Zhenhua just took over and continued, "What you said makes sense. Ours back then
The country has just been established, relying on self-reliance and hard work. This spirit has led us to the present, but."
When he couldn't say it, Qin Zhenhua glanced at everyone present: "However, now we should not only continue to carry forward this spirit of hard struggle, but on the other hand, we should also keep pace with the times and climb to the top, and
Is it suitable for our current national development? "We need to make progress, develop, and innovate. We only stay on the basis of past technology. Is it suitable for our current national development?"
After saying that, Qin Zhenhua sat down: "My question is over."
In front, someone suddenly applauded. This was a leader of the army. Obviously, he was very satisfied with Qin Zhenhua's words.
In fact, Qin Zhenhua has a killer weapon. The heavy trucks of the Iron Horse Factory were imitated by surveying and mapping, and were not authorized. The first machine factory bought the authorization. At the military parade, there was no problem with the heavy trucks of the first machine factory.
However, there are heavy trucks from Iron Horse Factory. If they are spread internationally, what kind of rumors will spread everywhere?
However, this sentence is too lethal. Now, thanks to the craftsmanship question just now, it has won the recognition of the superiors, so Qin Zhenhua didn't say it. After all, this is too hurtful, and it's even more
People who are prone to public anger are all started by surveying, mapping and imitation. What are you saying here that patent rights are infringed?
Liu Tiande swallowed a few mouthfuls of foam. He didn't expect that Qin Zhenhua would defeat him with a few problems. He originally hoped to win the recognition of his superiors on the heavy truck issue and then show it out. Now it seems that it is probably a big deal.
, However, we are not afraid of anything, we are also prepared.
