The wear resistance of the sole is very important, and it is necessary to have a professional test method, and use a special grinding wheel to check and test the wear resistance of the sole under a certain load, speed and time.

According to the different grinding wheels and time, there are Akron method, NBS method and Oriental national standard (GB) method, the latter also became the XM wear method, which has been established in 83 years, but this is only for large domestic factories, how can there be such equipment in small factories like Pingwang Town Rubber Shoes Factory.

Qin Feng thought secretly in his heart, it seems that we will have to buy a set of XM wear-resistant testing machines in the future, and if we want to become a world leader in the future, we must also have relevant inspection standards.

Buckman's eyes widened as he watched as Qin Jianguo took a long file, not knowing why.

The file is a long steel ruler with a series of file patterns on the surface, which can not only file wood, steel, and even bicycle tires.

Qin Feng took the file and brought the roasted shoe in Hans's hand: "I use the file to file this sole, and I can know how wear-resistant the sole is." ”

It turned out that I wanted to show the durability of the sole in this humble way! Buckman shook his head proudly: "No, no, you will never do this!" ”

"Why?"

"Experiments must be rigorous, and the sole abrasion test requires a professional machine, a specific load, time, etc., so that the results are comparable, and it doesn't make any sense for you to file a few times with a file."

"It's simple, we choose a minute, and if it's comparative, you can find a pair of shoes that you think are the best, as long as our shoes are more durable than your best shoes, isn't that okay?"

"The intensity of the test is also different, if you have to file it yourself, maybe you won't use it." Buckman continued to shake his head.

Qin Feng glanced at Andy, who was on crutches: "How about handing it over to a third party?" Andy was the operator of the test, and he was responsible for ensuring that the same force was used in both operations. ”

Buckman wanted to shake his head, but looking at Hans's face on the side, he nodded again and said, "Okay, that's it, the baltes that Mr. Hans just took off are the best jungle/tropical boots, just compare these shoes to your shoes!" ”

Qin Feng was like a mirror in his heart, it seemed that this guy was from Baltes Company.

It's an old German company with the full name "th. Baltes Schuhfabrik GmbH & Co. KG / Baltes Schuhtechnik und Arbeitsschutzprodukte GmbH", located in a small town on the border with the Netherlands, was founded in 1872 and insisted on using German raw materials to ensure the high quality of the products.

In addition to military and police shoes, they also offer sports, firefighting, security, labor, mountain boots, casual boots, and parade boots, and are a manufacturer of versatile boots.

In their eyes, the standard military boots of the German army are, of course, their meat, how can they tolerate being robbed by the Orientals, does the East have advanced shoe-making technology? It's still an unspeakable private enterprise!

The shoes under Buckman's feet are the latest shoes developed by their company, and the wear-resistant soles are the best in the world.

Since we want to compare, let's compare, let the Orientals know how good German technology is!

A table was set up under the tree, and Andy sat on the chair in front of it, holding a roasted shoe in his left hand and a file in his right hand at a ninety degree to the sole, ready to listen to Hans's order to start watching his watch.

"Wait! The soles of this shoe have been roasted, and the nature may have changed, so let's change this one! Buckman interjected again, who knows if the burned things will harden?

Qin Feng smiled and generously asked him to change his shoes, Hans looked at his watch, and shouted when the second hand pointed to 0: "Start!" ”

Boom, boom, boom! Andy tried his best to file the soles of his shoes, and after a few clicks, the soles barely moved, and after a dozen filings, finally the powder began to fall off and fall on the table, accumulating a fine layer.

"Stop!" Hans watched the second hand return to 0, exactly a minute had passed, and shouted.

"Okay, let's get another one!"

Andy shifted his position, got ready, and filed again as Hans had commanded.

Boom, boom, boom!

The black powder fell, although it was only a few strokes, Buckman's face darkened, why did it file so quickly? Andy, won't you just do it?

I just finished filing one, my arm should be sore, and my movements are slow!

Andy was still filing hard, and dense beads of sweat were oozing from his forehead, which showed that he had done his best.

Hans hasn't stopped yet, and there are already more things that have been filed than Oriental shoes!

This game, going to lose? Impossible, absolutely impossible, how can Oriental shoes be better than our German military shoes?

"No, Andy must have been out of strength, let's do it all over again!" Buckman snatched the file from Andy's hand.

This guy can't afford to lose! Qin Feng smiled secretly in his heart, he had just put forward various conditions, and he still regarded him as a strict German, full of craftsman spirit, but now it seems that he is just a clown who can't afford to lose.

Hans's face was not good-looking: "Buckman, what are you doing here?" ”

"I'm asking to retest the shoe, I suspect Andy just didn't use his full strength!"

Thinking of Andy's enthusiasm when he first met Qin Feng, Buckman felt that he had reason to believe that this Andy was oriented towards the East! And letting Andy operate it was also proposed by Qin Feng, why didn't he find out about this just now?

"Mr. Hans, let him test it again, and let him experience the strength of our private enterprises in the East." Qin Feng is very generous.

Buckman took the file, wiped off all the powder on it, felt the roughest part of the surface with his hands, and then went to a new place on the table, and took a deep breath: "Okay, I'm ready!" ”

Buckman went to a technical school, worked as a mechanic for three years, and often used a file to file parts, and he had a lot of force on hand, believing that he would be able to file the soles of these shoes with a pile of powder, and he would definitely file more than the baltes shoes!

At this time, Lorenz also returned, with gauze wrapped in his hands, still inhaling and sucking for cool air, but after seeing him, he immediately shouted: "Buckman, come on!" ”

"I will."

"Let's go!"

Following Hans's order, Buckman's hand held the file and filed it the sole, wait, something was wrong, why was this sole so hard? Doesn't file at all?
