"We succeeded!

Mr. Zhang, the curing temperature is 145 degrees, the curing time is 25 minutes, the surface is very smooth, there is no orange peel, the gloss is 85 degrees, the front and back impact is 50 kg of Niumi, and the adhesion is 0. ”

Liu Qi reported a series of performances to Zhang Xiaofan, and after listening.

Zhang Xiaofan nodded with great satisfaction and patted Liu Qi on the shoulder.

"You did a great job this time, and although I provided the recipe, you handled all aspects very well.

Next, continue the experiment to see if the curing temperature can be lower. ”

"Okay, I'll arrange for some small batches of large-scale tests right now.

If the test of my large machine is successful, I will report to Mr. Chen and order raw materials as soon as possible. ”

After more than a year of training, Liu Qi is now reluctant to leave the school, at least the tasks assigned to Zhang Xiaofan have now been completed relatively perfectly.

Zhang Xiaofan can't find much fault, sometimes people are forced out.

Zhang Xiaofan has always put a lot of pressure on Liu Qi, and he doesn't know that many very restrictive experiments have been completed by Liu Qi excellently, and he has indeed grown a lot in the past six months.

In the afternoon, Zhang Xiaofan left the laboratory directly, and the next thing was arranged by Liu Qi himself.

Sure enough, the next morning, Liu Qi reported to Zhang Xiaofan.

"Yesterday's test on the big machine was fully passed, although the experimental results were slightly off, and the curing temperature was 145 degrees Celsius for 27 minutes.

Everything else is not much different from yesterday's lab data, and I have arranged for the workshop to produce two tons. ”

Zhang Xiaofan looked at Liu Qi with satisfaction.

Apparently they must have worked overtime last night because the order was urgent, and they had to complete it within a week.

Of course, this two tons is only the first batch of finished products, and it is certainly not possible to produce them on a large scale now.

There is generally nothing wrong with some paint products when they are experimented.

However, once it is delivered to the customer, it will cause a large deviation due to the difference in the conditions of the two parties.

There is nothing wrong with the data from the manufacturer's experiment, but once it reaches the customer, various problems arise.

So for any new product, the output of the first batch will definitely not be too large.

In order to make this product available in large quantities at the customer's side, the results are about the same as those from the manufacturer's laboratory.

It's a waste of time, but it's a must, or the loss will be even greater.

So in the morning, Zhang Xiaofan called Du Dalian.

Tell her that the product has been produced and let him get ready to receive it.

Then a technician will be dispatched to provide on-site technical guidance to Duju Building Materials.

Technical guidance is the kind of thing that is going to be done for any new customer, new product.

Because any new customer and new product will not know enough about your product, and will not know enough about the performance of your product.

Therefore, when using your product, it may not be able to achieve the performance it should have, which often causes a lot of problems.

Therefore, it is very necessary to send a technician to provide technical guidance.

On the second day after the delivery of the first batch of finished products, Zhang Xiaofan received a call from Du Dalian.

"Thank you very much, Mr. Zhang"

"I'm very happy to be able to solve Mr. Du's problem, how about it?

"I am very satisfied, after the whole product came out, the effect is very good, and all the furniture splicing parts have not been damaged at all.

And there is also paint on the splicing parts, which is not much different from the main body of the furniture.

The only downside is that it's too long in the oven. ”

Zhang Xiaofan despised Du Dalian fiercely in his heart.

The time in the oven actually represents the curing time of the paint, and the time in the oven is actually a little longer than the curing time.

The reason is that no matter what kind of baking oven, when the workpiece is sprayed with paint, and then put into the baking oven, its heating is actually very slow, after all, the oven is too big, and the volume of the workpiece is generally relatively large, and the temperature on the workpiece reaches the temperature of the coating curing, the coating will slowly reflect, and after a period of time, it will react completely, so that the adhesion of the coating film to the substrate will be better.

However, Du Dalian really has to look forward to Shu, to know the most beautiful new materials, the low-temperature curing coating that is now being developed.

It is absolutely second to none in China, and there may be manufacturers who have developed this product, but it can be applied on a large scale, and it is definitely this one.

In 27 minutes, 145 degrees. Under such conditions, there are very few coatings that can be cured.

Even paints are hard to meet, except for those that don't need to be baked.

Of course there is no need for baked paint, I think everyone knows what it looks like.

The surface does not have any shine, and it can be uprooted with a light scrape with a fingernail.

This kind of paint can prevent rust, the effect is really not very good, a little sun and rain, then two or three months, there will be paint peeling.

The layer of oil on the surface of the car is paint, which needs to be baked, so it also belongs to the category of baking paint.

But if you look at the paint on the surface of the car, how good it works.

The surface is bright, you can pour out the figure, and the hardness is also very high, don't use your nails, even if you use a key to scrape off.

"Mr. Du, at present, the manufacturers that can produce a curing temperature of 145 degrees may be the only one you can find in the country.

And in a few years, you will find that we are still the only one that can meet your requirements, and in the future, if you ask the customer to be cooler, if the curing temperature is 120 degrees, then it will take him more time. ”

"I'm just complaining, after all, it's a bit too inefficient, and it looks like I can only add a baking oven.

In the past, I heard that their baking time is generally about 15 minutes, but the main thing is that you now have to bake the paint for more than 30 minutes.

So I had to add a baking oven to meet my efficiency requirements. ”

"At present, this is the only way, and low-temperature curing coatings generally take a long time, which I would like to learn more about.

This is the case for both domestic and foreign manufacturers.

If the curing speed is still very fast at low temperature, then its surface will definitely be very ugly, which is definitely not what Mr. Du wants. ”

"This kind of technical stuff, I really don't understand it as a layman, thank you Mr. Zhang, for solving my doubts.

Another point is that the price of this paint is a bit high, and when I calculated the cost today, I found that it was still a bit beyond my expectations. ”

This actually made Zhang Xiaofan speechless, and now we are the only ones in the country who can produce such products.

Do you think the price can be lower?

The profit margin of monopoly products is absolutely higher than many people imagine.

Otherwise, how will those hundreds of billions of trillions of group companies come from in the future?
