"First of all, the body-in-white, is the cab that has just been welded, from the selection of materials, it is best to use double-sided galvanized sheet, ordinary steel plate, the cost is low, but in the future, in use, there will be problems." Qin Zhenhua happily introduced.

The first step, the selection of steel plates, is exquisite! When the country's car industry was just beginning to rise, the early cars were easy to rust, just to pay attention to the cost, and even refused to use galvanized sheets.

"Then, the first step is to spray the primer, the primer is the most important, you need to carry out electrophoretic spraying in the dust-free workshop, electrophoretic spraying, I will not introduce it to you, otherwise it will be too wasteful of time." A simple spray paint, Qin Zhenhua can also say that the head is the way.

"After the primer is sprayed, it's followed by the primer. This primer is the last intermediate coat before topcoat is applied, the base content is between primer and topcoat, and the coating film is bright and semi-glossy. At the same time, it also has the effect of replacing putty. Qin Zhenhua said: "Here, I want to talk about putty, this putty used to be used by us, it is a coating with more pigmented fillers 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, the putty coating is easy to age, cracking, falling off, and the internal pore size is more after filming, resulting in the seepage of the topcoat and affecting the appearance, so in the advanced spraying process, there is no need for this process, of course, this requires the original flatness of our body surface is very high, that is to say, It needs to be guaranteed by our advanced stamping equipment and molds. ”

After all, until now, many people have not been to a machine factory, and they have never seen the manufacturing equipment of a machine factory.

A machine factory has everything, and it has been waiting for a long time to produce, and it has to cooperate with the Germans, spending hundreds of millions, what is the picture? It's this world-class technology!

"Finally, there is the topcoat, which we have to go through after spraying." Qin Zhenhua said: "Our paint baking process, brightness, wear resistance, corrosion resistance are incomparable to painting, after these processes, normal use, can ensure that ten years will not fade." ”

What the?

The things Qin Zhenhua said are all relatively mysterious, unless it involves related majors, they don't understand it at all, but now, when it comes to this conclusion, everyone can hear it clearly.

Ten years of color will not fade!

"Our previous cars, even if they used good paint, when the sun was exposed and the wind and rain blew, they would fade in two years, lose paint in three years, and rust in five years, which is the norm. I thought it was a paint problem, but I didn't expect that there was so much attention to it inside. ”

"Yes, I know now that we are sitting in a well and watching the sky." After Qin Zhenhua said this, many people present began to discuss.

That's right, the big guys are shocked, and they won't fade for ten years, what kind of concept is this? As long as there is no wiping and no paint peeling, then, within ten years, you don't have to care!

In particular, for the troops, the troops' cars must be kept in the best condition, and it can be seen that every time the troops' cars run out, they are washed very clean, and even the chassis is free of mud.

After all, if one of the screws rusts and breaks, the car can have problems, problems on the battlefield, which is absolutely not allowed and is a crime.

If the surface is smooth all the time, then it is easy to see the various problems that may arise.

"A heavy truck from a machine factory, can do this?" On the rostrum, a military leader asked.

"Yes, we use Mercedes-Benz technology." Qin Zhenhua said with a smile.

That's right, the Iron Horse Factory relied on its own perseverance to create the Iron Horse brand heavy truck, which looks exactly the same as the Mercedes-Benz heavy truck, which is just the appearance, what about the inside?

A simple cab painting process can say so much! We have adopted a full set of world-class technology to be able to achieve this level, what about the Iron Horse Factory?

At this time, Liu Tiande has already reacted, this Qin Zhenhua is here to promote their heavy trucks, such a comparison, even if the price of a machine factory's products is more expensive, but there is a reason why it is expensive.

"What's the use of this, it's a big deal that we paint every few years, and it's still the same as new." Finding that they were at a disadvantage, Zheng Heping opened his mouth there, and they could only refute it in this way.

Their heavy truck, without this kind of process, is not just a cab? Is it worth the effort?

It's just that this kind of thing is a little inappropriate to say it here, Liu Tiande frowned even more, this Qin Zhenhua, just this sentence, can launch a counterattack.

"Yes, our previous process was like this, it's a big deal to paint every few years." Qin Zhenhua just took over the conversation and continued: "What you said is also reasonable, our country was just 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, not only must we continue to carry forward this spirit of hard work, but, on the other hand, we should also keep pace with the times and climb the peak, right?" We want to progress, we want to develop, we want to innovate, and we only sleep on the basis of the technology of the past, is it suitable for the development of our country now? ”

After speaking, Qin Zhenhua sat down: "My question is over." ”

Earlier, someone suddenly applauded, this is a leader of the army, obviously, he is very satisfied with Qin Zhenhua's words.

In fact, Qin Zhenhua still has a killer feature not to say, the heavy truck of the Iron Horse Factory is a copycat of surveying and mapping, which is not authorized, and a machine factory bought the authorization, at the military parade, there is no problem with the heavy truck of a machine factory, but if the heavy truck of the Iron Horse Factory appears, if it spreads internationally, what kind of rumors will spread?

It's just that the lethality of this sentence is too great, and now it has won the affirmation of the superior leaders by relying on the process question just now, so Qin Zhenhua didn't say it, after all, this is too hurtful, and it is easy to make public anger here, everyone started by surveying and mapping imitation, what are you talking about patent infringement here?

Liu Tiande swallowed a few mouthfuls of spit, he didn't expect that Qin Zhenhua would defeat him with a few problems, originally hoping to win the affirmation of his superiors on the issue of heavy trucks, and then be able to show it, now it seems that it is estimated to be enough, but this is not afraid of anything, we are also prepared.
