"Hehe," Bao Feiyang laughed, waved his hand and said, "Chairman Han, you're too worried." I don't have to sign any purchase contract, and I don't have to pay any technical service fees......"

For Fangxia Ceramic Chemical, as long as you do a good job of keeping the anion green body enhancer confidential, you don't have to worry about the sales problem at all, even if Jiangguan Ceramics Company does not sign a three-year purchase contract, it will eventually go to Fangxia Ceramic Chemical to buy the green body enhancer. So at this time, Bao Feiyang put on a high profile, the company's interests were not lost in the slightest, and Han Xiaojian could be sold a big favor. As for the technical service fee, it is not that Bao Feiyang does not want it, but the essence is that this amount is difficult to determine. If the price is too high, Han Xiaojian will definitely feel too much after hearing the solution to the problem, even if he doesn't say anything at this time, but he has a mustard in his heart, and it is still not good for the long-term development of Fang Xia Ceramic Chemical in Yuehai City. However, if the price is too low, it has no practical significance for Bao Feiyang, so it is better not to have anything, and directly sell Han Xiaojian a favor, which can be regarded as a boost for Fangxia Ceramic Chemical's exhibition in Yuehai City......

"What's so embarrassing? This contract must be signed, and I must pay the technical service fee! Han Xiaojian thought that Bao Feiyang was fake politeness.

"There really isn't a need," Bao Feiyang said, "because the reason for the problem with the production formula that you Jiangguan Ceramics bought back is very simple......

Han Xiaojian saw that Bao Feiyang wanted to directly say the reason, and then he knew that he was a bit of a villain's belly, and he was ashamed in his heart, so he quickly pricked up his ears, and Hao Wanshu looked at Bao Feiyang intently, ready to listen to him reveal the reason.

“…… It's because of your company's production water problem. Bao Feiyang paused slightly, and this time he said the reason.

"What? Is it the problem of our company's production water? ”

Han Xiaojian didn't understand it at all, and looked directly at Hao Wanshu, the chief engineer of the Technology Department. Although Hao Wanshu is the chief engineer of the technical department, at this time, he heard Bao Feiyang say that the production of qualified high-grade tiles is a problem of production water, and he was confused for a while, and there was no concrete concept at all, and he only looked at Bao Feiyang in surprise and asked: "Is it a problem with the production water, is it not a problem with the formula provided by Spain?" ”

"yes, isn't there a problem with the Spanish recipe?" Han Xiaojian also repeated. In Han Xiaojian's consciousness, since there is a problem with the tiles produced according to the formula provided by Spain, then there must be something wrong with the formula.

"Yes, it's not a problem with the high-end tile formulas that Spain provides." Bao Feiyang said firmly, "It's your company's production water problem. ”

Looking at the surprised expressions on Han Xiaojian and Hao Wanshu's faces, Bao Feiyang laughed again and said, "Do you think that I haven't even read the ceramic tile production formula you bought, so I dare to be sure that it is not a problem with the production formula, I think it is incredible, and even suspect that I am talking nonsense?" ”

Han Xiaojian and Hao Wanshu thought exactly this in their hearts, but they didn't dare to say so, they just touched each other's eyes, then smiled and said, "I don't think you're talking nonsense, I just think it's incredible." ”

"Hehe," Bao Feiyang didn't reveal it, but just asked: "I just want to ask, do you want to use sodium carboxymethyl cellulose in the production formula of this high-grade floor tiles?" ”

Han Xiaojian had seen the production formula, but he didn't remember whether there was a raw material such as sodium carboxymethyl cellulose in it, so he looked at Hao Wanshu, as the person in charge of the technical department, Hao Wanshu certainly remembered that this production formula contained sodium carboxymethyl cellulose, but he was very shocked, how could Bao Feiyang know this. Although he knew that Bao Feiyang had been to the production site, in addition to the basic production raw materials used in most ceramic tiles, such as feldspar, quartz powder, and alumina powder, the rest of the more special raw materials were changed to packaging, and only the secret code known to several high-level personnel of Jiangguan Ceramic Technology Department was marked on it. This is also a common practice for the vast majority of ceramic enterprises, mainly to prevent the leakage of production formulas. Hao Wanshu really couldn't figure it out, how did Bao Feiyang know that the production formula contained sodium carboxymethyl cellulose, could it be that someone in the senior management of the technology department leaked secrets?

Seeing Hao Wanshu's suspicious appearance, Bao Feiyang smiled again and said, "Hao always suspects that someone in your technical department has leaked secrets?" I don't know if I leaked it to others, but absolutely no one leaked it to me. I knew that sodium carboxymethyl cellulose was used in the production recipe because I saw this raw material at the production site......"

Hao Wanshu was shocked again, just by the naked eye, he could distinguish sodium carboxymethylcellulose from hundreds of raw materials without any packaging labels on the scene, what kind of technical level is this? Hao Wanshu believes that those experts from the Guangdong Ceramics Research Institute can't do it, and even the foreign experts sent from Spain can't do it. I don't know how this young man who is less than twenty years old in front of him did it, no wonder Fangxia Ceramics Chemical will hire him to come over as a special technical consultant, it turns out that he is such a genius.

"Okay, let's get down to business," Bao Feiyang continued, "although Chairman Han and Mr. Hao haven't answered my question yet. But seeing Mr. Hao's reaction, I knew that what I said was right, your production formula does contain sodium carboxymethylcellulose. The reason why there is a problem with the tiles you produce is mainly related to the sodium carboxymethyl cellulose. ”

"Something to do with sodium carboxymethylcellulose?" Hao Wanshu frowned and thought for a while, and said: "But we also used sodium carboxymethyl cellulose in the small and pilot tests, so why didn't there be a quality problem with Yan zhòng?" Why did the quality problem of Yan zhòng only appear when it was officially mass-produced? ”

"Speaking of which, I would like to mention the problem I mentioned earlier, that is, the problem of your company's production water." Bao Feiyang said, "Your company uses water from its own wells for production, right? ”

"Yes!"

Without Hao Wanshu, Han Xiaojian can answer this question. Ceramic enterprises are large water users, and the water consumption is also considerable. Jiangguan ceramics company this self-provided well, or a few years ago when Jiangguan ceramics was just established, Han Xiaojian in the water bureau dragged the relationship to play a self-provided deep-water well, with this self-provided well, Jiangguan ceramics can save a lot of water every year, even though the benefits of Jiangguan ceramics company is very good, but the tradition of using self-provided well water has been retained.

"Sodium carboxymethyl cellulose has a characteristic," Bao Feiyang said, "There will be no problems with your normal water in the south, but once you use water with high hardness or high mineralization, it is easy to produce residues when dissolved." The mineralization content in the self-provided well water of your Jiangguan Ceramics Company is relatively high, so during the mixing process, the sodium carboxymethyl cellulose is not completely dissolved and cannot be evenly distributed in the tile body, so when it is baked in the kiln of the automatic production line, it is easy to produce bubbles, pockmarks, cracks and other quality problems. ”

"So, it's not that there is a problem with the production formula of the high-end floor tiles you bought, but that there is a problem with the water used for your production." Bao Feiyang finally concluded.

"Consultant Bao, it's a little wrong. Groundwater in the north is generally a problem of high hardness or high salinity, but there is basically no problem in the groundwater in the south, and the groundwater in Guangdong City is also dominated by soft water......," Hao Wanshu asked rhetorically.

"Yes, the groundwater in most areas of Yuehai City is soft water," Bao Feiyang said, "but the groundwater in the place where your Jiangguan Ceramics Company is located is not soft water." Because this part of the area is dominated by limestone underground, the limestone itself is easily soluble in water, and there are typical karst caves underground, so the mineralization is very high. ”

Bao Feiyang can know these because in the last generation in 2006, Yuehai City in this generation of construction of the first ring of the north line of the collapse, and then after drilling, this generation is now distributed a large area of underground beaded large karst cave group, and the factory area of Jiangguan Ceramics Company is also located on this large underground karst cave group.

"Even though our company's self-supplied well water has a high degree of salinity, but the self-supplied well water is used in the small and pilot tests, why is there no quality problem?" Hao Wanshu still couldn't figure it out.

"This brings us to the properties of sodium carboxymethylcellulose." Bao Feiyang said: "In the ceramic enterprises in the north, if you want to use sodium carboxymethyl cellulose, because the salinity or hardness of water is relatively high, it will basically be dissolved in advance with water with relatively high temperature. This is called warm water pre-dissolution, which can promote the complete dissolution of sodium carboxymethyl cellulose. Because the water used by southern ceramic enterprises is soft water, it is rare to take the warm water predissolution method to directly completely dissolve the sodium carboxymethyl cellulose. However, when it comes to your Jiangguan ceramics, the situation is more special, because the mineralization of self-provided well water is very high, so it is necessary to take warm water predissolution method to make carboxymethyl cellulose sodium fully function. ”

"And now, it's summer, and it's hot. The water pumped out of the self-supplied well is stored in a large tin tank of the water tower, and the temperature of the water in the tin tank is heated under the strong sunlight. As for this, I personally verified it in your production workshop at the time, and the water pipe was turned on for seven or eight minutes, and the water flowing out of it was still hot. Therefore, at a certain time, the heated water in the iron can is exactly in line with the characteristics of sodium carboxymethyl cellulose that needs to be pre-dissolved in warm water. Bao Feiyang continued, "There is not much water in the small test and the pilot test, and the water stored in the iron tank of the water tower is enough, so the sodium carboxymethyl cellulose is completely dissolved, and it is very evenly distributed in the tile body, and the quality of the tiles produced is relatively good." Once the scale is put into production, after the water stored in the iron tank of the water tower is used up, what flows behind is the deep groundwater that has just been pumped out of the self-provided well, the water temperature is 178 degrees, and the salinity is high, so it is impossible to dissolve all the sodium carboxymethyl cellulose in the mixing tank, and the distribution is uneven in the tile body. This is also the reason why when it was officially put into production, the quality of the tiles at the beginning was better, and the tiles behind had various problems one after another! ”

"Huh?" Han Xiaojian was dumbfounded when he heard this. He always thought that this problem affecting the quality of ceramic tiles must be a very complex problem, but he didn't expect that the answer would be so simple here in Bao Feiyang. But such a simple answer, if it wasn't revealed by Bao Feiyang, they would never have thought of it.

It's really difficult that those who won't, and those who know it won't! (To be continued.) Please search for Astronomy, the novel is better and faster!)
