Seeing that Tan Jinxuan, the chairman of Hong Kong Rixing Ceramics Machinery Company, who was extremely tall in their hearts, turned into a curious baby in front of Hao Shuang, and asked for advice. Wang Daojun and his two section chiefs naturally sat upright, looking at Hao Shuang with all his attention, waiting for him to give the answer.

"Well, we have to start with the technical service contract signed by Taihu Zhenghong Ceramics Company and Neiqi Company." Hao Shuang poured a cup of boiling water into the cup, took a sip, and neutralized the taste buds that were a little sour and refreshing that were stimulated by the Oriental Divine Water. Then he began to answer Tan Jinxuan's questions calmly.

"According to the contract, Neiqi Company will provide technical services to Zhenghong Ceramics Company, including the glaze formula for the washing tank. The technical files of Zhenghong Ceramics Company also record that in February 1979, they sent a total of 12.5 tons of ceramic raw materials from Taihu to Neiqi Company."

"After testing these raw materials, Neqi Company spent more than two months conducting industrial tests, and finally provided them with the blank and glaze formula suitable for this horizontal washing tank micro-pressure grouting production line based on the raw materials provided by Zhenghong Ceramics Company."

"Now the man named Pan also took medicine according to the prescription and directly took the glaze formula of Neiqi Company to Caifeng Ceramics Company for use, without considering the different production conditions between Caifeng Ceramics Company and Zhenghong Ceramics Company, which ultimately led to the slurry running problem of the production line."

Tan Jinxuan has always regarded the standard glaze formula provided by Neiqi Company as a killer. At this time, he heard from Hao Shuang that it was the glaze formula of Neiqi Company that caused the production line to run off, and he suddenly felt that his entire view was subverted.

"Will there be any problems when producing Neiqi's own formula on Neiqi's own production line?" He poured a cup of Oriental Divine Water and was shocked.

"Yes!" Hao Shuang nodded and replied: "Oranges grow in the south of Huai, which are oranges, which are oranges grow in the north of Huai. There is no problem with the same glaze formula for the Taihu Zhenghong Ceramics Company, but when they arrive at Caifeng Ceramics Company, there will be problems."

“There are several key factors in the middle.”

"First, the production water used by Taihu Zhenghong Ceramics Company is surface water. Surface water is soft water and has a relatively low mineralization degree."

"Caifeng Ceramics Company uses production water to groundwater extracted from its own wells in the factory."

"Because this groundwater belongs to shallow-slit karst water on the southern foot of the Taihang Mountains, its mineralization and hardness are very high. According to the data of Caifeng Ceramics Company's Biotechnology Department, the total hardness of groundwater extracted from its own well is 906.7 mg/L, and the total mineralization is 1108.92 mg/L, of which the sulfate ion content is as high as 312.55 mg/L, and the water chemical type is calcium sulfate-magnesium sulfate type."

Wang Daojun and the head of the Biotechnology Department both nodded. Not only did Caifeng Ceramics Company's self-produced wells have high hardness, but the groundwater in the entire Tianbei City area has high hardness, so that a thick layer of scale will be formed if the kettle is not cleaned for a day.

"So even though Caifeng Ceramics Company adopts the same raw material formula as Zhenghong Ceramics Company, during the water injection and stirring process, the magnesium sulfate ions and calcium sulfate ions contained in the water will react chemically with the raw materials in the high-level mud tank, resulting in changes in the viscosity and fluidity of the ceramic mud."

“This is the first factor that causes sludge to run.”

The people at the dinner table suddenly realized.

If Hao Shuang hadn't explained it, they wouldn't have expected that the groundwater of the self-produced well produced by Caifeng Ceramics Company would be one of the culprits in the production line's slurry run.

"The second factor is the production of raw materials." Hao Shuang continued to explain: "On the surface, the raw material formula used by Caifeng Ceramics Company is exactly the same as the raw material formula used by Zhenghong Ceramics Company, but in fact there is still a big difference."

"Because the Taihu area itself lacks high-quality raw materials such as kaolin, refractory clay, high alumina bauxite, etc. needed to produce ceramics, Zhenghong Ceramics Company's raw materials mainly rely on imports from Neon Kingdom and South Korea."

"Compared with the ceramic raw materials in mainland China, the kaolin, refractory clay, high alumina bauxite and other raw materials in Neon Kingdom and South Korea are highly standardized. Zhenghong Ceramics Company only needs to mix water and stir and put it into a ball mill to grind, and then it can be put into high-level mud tanks on the production line for direct use. Only a very small amount of raw ore and vegetable waste need to be refined."

"The raw materials used by Caifeng Ceramics Company are of low standardization and are basically raw ore. Caifeng Ceramics Company needs to be reprocessed before it can be put into high-level mud tanks for use."

"Limited from the equipment and technical level of Caifeng Ceramics, the accuracy and stability of raw materials after processing cannot be compared with that of Neon Kingdom and South Korea. Therefore, even though the proportion of various raw materials is no different from the formula of Zhenghong Ceramics, it will eventually lead to an increase in the specific gravity and viscosity of the ceramic mud."

"Combined with the first reason, the final reaction is on the production line. The buoyancy on the ceramic mud inside the model is much greater than the total pressure of the compression spring on the upper mold frame, which ultimately leads to serious slurry running."

"The first solution I gave is to extend the slurry inlet time. If the slurry inlet speed slows down, the uplifting pressure required to be subjected to within the model will naturally be reduced."

"The second is to replace the compression spring in the upper mold frame, and replace the Φ4 spring with the original design maximum pressure of only 488.05N to the Φ6 spring with the maximum pressure of 1273.04N."

"Reduce the upflow pressure of mud and increase the compression pressure of the mold frame. In this way, the slurry running problem will naturally be solved!"

I see!

At the wine table, Wang Daojun and the two section chiefs of Caifeng Ceramics Company changed their eyes to looking up at Hao Shuang.

I really didn't expect that the funds hidden behind the two simple solutions proposed by Hao Shuang at the production line site were such deep technical knowledge. It seems that college students are college students, far from being comparable to local experts who have experienced entirely based on production practice.

Compared with the three Caifeng Ceramics Company, although Tan Jinxuan and his two technicians did not rise to the point where they needed to look up to Hao Shuang, they were also mixed.

Unexpectedly, they came from developed areas of Hong Kong and Taiwan, but today they were taught a lesson by a young man in the backward mainland area, shattering their pride and self-esteem in the so-called developed areas.

I really didn't expect that the mainland, which was backward on the surface, had such a deep foundation. Any college student could analyze the production line of the most advanced international ceramic companies like Neiqi Company to clearly analyze it.

Turning the glass in his hand, Tan Jinxuan suddenly had a thought in his mind: If he could meet Hao Shuang earlier, what would he do to spend a high price of 1,500 US dollars per month to invite Pan Jiahao from Taihu?

Although what Hao Shuang shows now is only the tip of his iceberg, Tan Jinxuan firmly believes that as far as Neiqi Company's production line is concerned, Hao Shuang must be far better than Pan Jiahao's idiot!
