Recently, in the Huobu Park of Changshan Economic and Technological Development Zone, Zhejiang Zhefeng New Materials Co., Ltd. No. 10 production line is in full swing. This production line mainly produces high -end paper -based materials based on food card paper. The annual production capacity of 300,000 tons after production can increase the output value of 2 billion yuan.

Papermaking is one of the four major inventions in my country. The application of paper products is very wide, and paper for specific performance and use has also emerged. This has produced a special paper industry. In Luzhou, known as the Chinese special paper industry base, a good news recently came: After years of independent research and development, Zhefeng New Materials has established a complete liquid food sterile packaging original paper production line, which has changed the current status of the long -term dependence on imports in this field. Essence

What exactly is a special paper? How did you make it? A few days ago, we came to Zhefeng New Materials to experience a papermaking.

If there is no innovative enterprise, there is no way out

"Special paper has a wide range of applications, and it is becoming more segmented and professional." As soon as he entered Zhefeng New Materials, Shi Junqi, deputy general manager of the company, led us to the special paper exhibition hall. Dozens of special paper products developed by the enterprise Show here neatly.

Under the guidance of Shi Junqi, we started to distinguish the types of these special paper one by one: for the packaging of medical packaging paper for the one -time medical surgery mask, it is used for the labeling paper for the courier electronic face. Inside is thin printing paper ...

Shi Junqi told us that due to the many types of special paper, there are many market participants, and there are many market participants, and the industry competition is quite fierce. During the talk, Shi Junqi handed us a piece of paper printed with the word "pure milk".

We observed it carefully and kneaded again. The surface of the paper was white, smooth and delicate, but there was no obvious difference between the appearance and touch and the ordinary paper. We even tear up the paper and found that the strength of the paper was not as shifting as cowhide paper.

"Don't underestimate this 'paper'. This is such a piece of paper that can only rely on imports in the past." Facing our doubts, Shi Junqi began to answer, because the flavor of liquid food, nutrition retention, storage of anticorrosive, and food safety The requirements are extremely high, that is, the performance requirements such as liquid food sterile packaging original paper are extremely high. Therefore, the research and development and production barriers are high, and the technology has long been monopolized by foreign companies.

However, from the perspective of industry development, China is one of the world's largest consumer consumer countries. Almost all dairy products need sterile packaging, and liquid milk is the top priority. unlimited.

"Aiming at the segmentation of liquid food sterile packaging raw paper, Zhefeng New Materials has begun to make efforts." Shi Junqi has been engaged in the special paper industry for 26 years, and he is also a leading talent in Zhejiang Province. He introduced that because there is no ready -made data to learn, the R & D team can only summarize the laws in continuous experiments. "The chemical auxiliary is allocated, and the R & D team has tried hundreds of times. At the critical stage, the R & D team spends almost more than ten a day a day. Repeated experiments in an hour. "

In the end, the enterprise took a year to create the original paper in the pillow bag in the sterile packs of liquid food, and established a complete raw paper production line. The product also harvested the cooperation with Swedish natolia with high cost performance, and it is more domestic in China. Family well -known dairy companies provide dairy packaging.

Old craftsmanship and new technology blend

Leaving the Special Paper Exhibition Hall, under the guidance of Ding Wei, the company's Minister of Production and Technology, we came to the production workshop of the original paper of liquid food sterile packaging.

"First put on sterile clothes, shoe covers, hats and masks." Ding Wei reminded carefully. We have entered the workshop at the level of cleanliness to reach the operating room level. The machine is loud, the papermaking machine equipment is constantly running, and a roll of white paper appears in front of us.

"'The paper is not easy, seventy -two workers', this is a folk proverb describing papermaking. , Soaking, rinsing, fragmented, pulp (adding aids), tanning paper, knife, packaging and other processes, can still be called 'seventy -two workers'. "Ding Wei, who graduated from the paper -making professional, said, From ancient times to the present, the "seventy -two workers" showed the wisdom of papermaking.

"The papermaking process is similar. Why can we create special paper with different products?" Ding Wei sold a governor when he heard our questions. "You know when you're a while."

Following Ding Wei, we came to the material selection area. "The key to manufacturing special paper is the selection and ratio of raw materials, as well as adding different chemical aids to give different characteristics of paper."

"You see, this is the raw material for papermaking -plant fibers." Ding Wei took out a piece of plant fiber to tear it to us, "This kind of short and uniform is short fiber. Short fiber can provide thickness, long fibers, long fibers It can also meet the needs of high intensity. "We picked up another plant fiber to tear away. This long fiber is long fiber. "The choice of fibrous fiber and short fibers in the choice of liquid food sterile packaging in the choice of fiber raw materials." Ding Wei introduced. In ancient times, people used tools such as sticks and stone mortar to pound paper fiber raw materials. This process was vividly called "beating". Nowadays, in the tank of the pulp, the fiber raw materials can be seen in circulation in the groove. The rotating flying knife and a fixed bottom knife have produced the pulp effect.

"Palm is to change the shape and nature of the slurry fiber and improve the binding force between fibers. It is the prerequisite for creating good paper. The so -called" paper is made from the pulp "." Ding Wei said.

Next to the pulp machine, several other injection machines are also working, and chemicals such as glue appliances and glue in the slurry are sent to the machine proportionally. In this way, the manufactured paper can meet the performance requirements of a sterile packaging of liquid food.

Walking along the production line, we saw that after a process of process, a roll of white paper was made. The last level of production is to test, and workers will check the quality of paper.

"You can try." Ding Wei said to us with a smile. We spread a piece of paper about 1 meter long and about 30 cm wide on the detection table, turn on the bottom lights, side lights, and look down. Under strong light, the paper becomes transparent. Impurities will be sour after a while.

"This is only 1 meter. Workers need to sample more than 100 meters of paper at a time to see whether there are impurities, defects, and flaws in it." Ding Wei said that skilled workers are valuable wealth of the enterprise. However, the realization of product performance and the control of product quality are far from enough. The manufacturing of special paper is the integration of old craftsmanship and new technology.

After digital transformation in the production line, the "surface defect high -speed online detection system" is to control insurance for the quality control of paper. The system is still constantly optimizing and upgrading to ensure that the small particles in the paper can be quickly detected.

Entering "unmanned factory"

In the production workshop, we want to experience more papermaking processes, but Ding Wei "declined". "You see that there are few workers here. Modern papermaking. Workers only need to sit in the control room to master the operation of the equipment. "

There is a 20 -square -meter control room not far from the production line. There are four computers arranged neatly in the room. The computer screen shows the operating power and real -time state of each link of the birth line. Essence

"Well ..." The alarm sounded in the workshop, and the green light in the wall of the five -color light on the wall of the control room also lit up. "This is to remind a roll of paper that has been produced, and start preparing the production of the next roll of paper." Ding Wei said that the fully automatic assembly line has greatly improved the production efficiency of special paper. According to estimates, a full -automatic assembly line can reach 800 meters per minute, and the production of 24 hours a day can reach 280 tons. Compared with the past semi -automated assembly line, the production capacity increases by nearly 70%.

Ding Wei told us that Zhefeng New Materials is one of the two pilot enterprises of two "two -way" pilot in Luzhou. At present, companies are deploying MES (manufacturing execution system). MES is a production management system for the workshop execution layer. It is like a "smart brain", providing information transmission and data support for the complex situation of the production site. Through the in -depth combination of informatization and industrialization, production management has further refined, standardized, and scientific, and promotes enterprises to march towards the direction of "unmanned factories".

"In the past, most of the energy of the engineer was on maintenance equipment, and now you can spend more energy on technology research and development." Ding Wei introduced that the core of the "unmanned factories" is not completely eliminated, but uses machines to use machines to use machines from from machines to use people from from machines to use people from from machines to use people from from machines to use people from from machines to use people from from machines to use people from from machines to use them from machines from from machines. Performance and simple brainpower labor are liberated, playing more creative and challenging roles.

Unmanned, intelligent, and digitalization has greatly promoted the adjustment of corporate talent teams, and also allowed enterprises to cultivate more compound talents and enhance core competitiveness. It is understood that in recent years, Zhefeng New Materials has led a number of national and industry standards that participated in the formulation of the special paper industry, including the national standards for the formulation of dictionary paper, participating in the formulation of national standards for carbon -free paper, vacuum -plated original paper and heating sublimation. Industry standards for transferring paper. At present, enterprises are leading the formulation of dust -free paper -free paper, baking original paper industry standards, and Zhejiang manufacturing standards for hot -promoting transfers.

At present, special paper is still the "blue ocean" of the domestic paper industry. Shi Junqi revealed to us that the enterprise started to make a long -term plan: on the one hand, it continues to increase investment and expand production capacity. A production line of "annual output of 300,000 tons of high -end paper -based materials" is accelerating the construction. Successful, will be officially put into production at the end of this year; on the other hand, it will further optimize and improve product quality, give play to the leading role of industry leaders, attract more supporting companies to settle in Changshan, and truly form industrial agglomeration and development.
