Chapter 560

"The acceptance standard must be in accordance with the national standard."

Board cuntou man spoke loudly and sounded confident: "we implemented it according to gbt18883-2002, that is, the indoor standard is less than or equal to 0.01 per cubic meter."

"For some companies, the standard is less than or equal to 0.08 per cubic meter."

Zhong Tianzheng doesn't know whether the value of 0.01 is large or small, but according to what the board inch man said, their operation should also be quite standardized.

"Did you get it yourself and then test the results yourself?" Zhong Tianzheng sent out the question point again.

"It depends on the individual."

The man nodded and said, "if the customer has a request, we can provide them with the test results issued by CMA laboratory. This test result has legal effect."

"However, this is also a fee, which will increase our additional expenses. Therefore, if customers do not ask, we will use our own machine to test them, and the data is also accurate."

But Zhong Tianzheng heard it.

In other words, they use their own machines to detect. The data is certainly not so accurate, but it can also be used.

Ah Xiang soon thought of the mistake: "what if your CMA data is fake?"

"Hehe, this beautiful lady, I worry too much here."

Board cuntou smiled and shook his head, disapproving: "you think this CMA test report is so easy to fake. This is a nationally recognized laboratory and very authoritative."

"Once you falsify the test data, you will be disqualified from the laboratory. The subsequent consequences are also very serious, so it won't be said that any laboratory will be willing to falsify."

"OK."

Ah, Xiang nodded and said nothing more.

"After talking for so long, both of you should know about it? Want to do air treatment? There must be nothing wrong with looking for us. Don't worry. "

As he spoke, the man took out his company's brochure from the shelf on the side: "you can understand it in detail. We have met a lot of young couples like you, all of whom come to us for governance."

The goods probably didn't see the scene that Zhong Tianzheng showed his id just now, so he mistakenly thought they were door-to-door customers, so he said enthusiastically.

They just wanted to shake their heads to deny and show their identity, but the man didn't give them a chance at all. He pointed to the white bottle on the shelf and continued: "you see, this is our medicine, biological enzyme technology, you know?"

"Biological enzymes?"

Zhong Tianzheng glanced at the woman behind him. The woman was talking about wechat and smiling. It is estimated that she didn't pay attention to what they said just now, so she didn't point out her identity and asked, "what is a biological enzyme? Can I have a look? "

Ah Xiang also looked curiously at the bottle brought by the man.

Don't say yet.

Ah, Xiang actually cares about the indoor air pollution. She's not allowed to decorate the house in the future. It's always right to know.

The man at the head of the board was full of curiosity when he looked at the beautiful face, and knew that what he said just now played a role.

"Biological enzyme is a new liquid medicine for removing formaldehyde. It is a famous foreign brand. The main principle is that biological enzyme covers the wood surface, micro molecules capture formaldehyde, decompose it into water and carbon dioxide, and then volatilize it."

This point is well understood if it is taken literally.

The chemical formula of formaldehyde is HCHO or CH З O. they say that it can be separated into water h З O and carbon dioxide CO З under the action of biological enzymes.

But if you think about it carefully, you will find another contradiction.

Board inch men have said one of their governance methods before.

Sealing - treatment - ventilation - detection.

If formaldehyde is decomposed into water and carbon dioxide, this ventilation step is redundant.

Whether I have ventilation or not, shouldn't the existing formaldehyde in the room no longer exist?

It's all water and carbon dioxide.

however.

This is just a self guess of Zhong Tianzheng.

The real situation must be that this thing is effective, otherwise it would not be allowed to be listed and distributed on such a large scale.

The board inch head man opened an unsealed biological enzyme agent and put a bottle cover on the table.

The whole reagent is a light yellow with slight bubbles, and the liquid is mixed with a small amount of yellow condensed solids.

This condensate is what they call a biological enzyme.

Ah, Xiang blinked, his eyes filled with a strong thirst for knowledge: "it's this thing. It's really effective. It can remove formaldehyde?"

"Let's do a simple experiment."

The board cuntou man pondered for a while and was ready to go on.

doorway.

Footsteps sounded.

Mixed with the voice of a woman.

"Sleeping trough, the boss is coming."

The board cuntou man pushed the man lying on the table to sleep, woke him up, then faced Zhong Tianzheng Ah Xiang, pointed to the brochure and looked like he was explaining the materials to them.

We can tell from his action just now.

Chen Jiani should be a very powerful role.

Otherwise.

His employees should not be scared like this.

"Oh, here comes the customer?"

Chen Jiani looked down at the whole office. Her sight fell on Zhong Tianzheng, stopped on his handsome face, and then fell on Ah Xiang.

This time.

doorway.

A man followed him, glanced at Zhong Tianzheng, and said in a loud voice, "President Chen has done a good business recently. Customers have come to know the details."

"Where, where."

Chen Jiani obviously used this sentence very well. She looked at the man with a smile, then gathered behind the man and stepped down one by one.

"President Chen, boss Meng."

Several employees began to greet them.

"Ha ha."

Zhong Tianzheng squinted at them.

The boss Meng is about 1.8 meters tall. He looks young. He should be only about twenty-five or six years old, but his words and deeds with Chen Jiani are full of intimacy.

Go beyond the intimacy between partners or friends.

If Zhong Tianzheng remembers correctly, he remembers that Chen Jiani should be divorced now. How can he have such a close partner?

Therefore, the relationship between the two of them, Zhong Tianzheng, is still somewhat speculative.

Zhong Tianzheng put away his mind: "we're here to find Chen Jiani, President Chen."

"Look at you, don't you know how to pour water when people come here? Is there such a slight on President Chen's customers? " Boss Meng then scolded the people on the side.
