According to statistics, the annual output of bitumen in China is about 4.5 million tons, of which about 20% of the asphalt is packaged in old iron drums. It is these iron drums that bring pollution and waste in all aspects of transportation, storage, handling, use, etc. The improvement of iron drum packaging has become the focus of attention at home and abroad. Many countries have invested capital and manpower to develop bitumen flexible packaging instead of iron drum packaging.
The engineers and technicians of Dalian Xinke Packaging Materials Co., Ltd. have solved many key technologies such as sealing, compounding and anti-adhesion in the production process of asphalt soft packaging bags after many years of research, and made the flexible packaging bags degradable, and successfully produced environmentally-friendly products. Anti-sticking asphalt soft packaging bags fill a gap in China's packaging products.
The soft packaging bags developed by Dalian Xinke Packaging Materials Co., Ltd. are paper materials, ie, kraft paper on both sides and fibrous web-shaped ribs in the middle, with specifications of 25 kg and 40 kg, respectively. Different from ordinary cement bags and chemical fertilizer bags, its high temperature resistance, oil and water resistance, non-toxicity, anti-adhesion and degradability and so on. Among them, the sealing tapes, anti-adhesives, and compounding agents for the upper and lower bag mouths are difficult problems to solve in the development of this product at home and abroad.
The asphalt soft-packaging bags developed by Dalian Xinke Packaging Materials Co., Ltd. ended the history of asphalt used in drum packaging, and opened up a new path for the improvement of similar other products such as paraffin wax and rosin. According to statistics, due to the use of iron drums in China, the loss of asphalt accounts for about 5% of the total. With only this one, the use of asphalt soft bags can reduce losses by more than RMB 60 million. Zheng Guangdi, deputy director of the Ministry of Communications, pointed out at the national key scientific and technological breakthroughs congress held by the Ministry of Communications that the implementation of flexible packaging for road asphalt is a revolution in changing asphalt storage, pipe, and transportation.
Dalian Daily, Liaoning Economic Daily, Peninsula Morning News and other media reported that Dalian Xinke Packaging Materials Co., Ltd. had successfully developed environmental friendly asphalt soft packaging bags, saying that Dalian Xinke cracked the world's difficult problem of asphalt packaging.
Asphalt is an important material in highway construction, but due to its characteristics, it brings many problems to transportation, storage and use. For example, bitumen is in the state of mucilage during production, and the liquid-filling temperature reaches 180°C-280°C. The package requires high-temperature resistant conditions; after cooling, a solid state appears again, which sticks to the package, and the asphalt is often removed from the package. Heat it up. The use of iron drums is often done by heating or using a torch to cut the drum to pour the asphalt. Among them, due to reheating during use, the cost per ton increased by 150 yuan. In addition, it is very easy to accidentally cut the asphalt barrel with a welding torch. Recently, Dalian Daily reported such a news: A worker on a construction site in Chaoyang Street, Zhongshan District, Dalian, used electric welding to cut the iron bucket filled with asphalt, causing burning of the asphalt and explosion of the iron drum, resulting in the analysis of the skull of the worker. , brain contusion and death. Events like this have happened in other places too. Then, the pollution caused by scrap iron barrels is also very serious. The iron drums packed with asphalt are not only impossible to recycle, but even the construction site is contaminated. It is often the case that nearly 100 waste asphalt barrels have been thrown away on a completed road construction site, the ground is covered with asphalt, grass is not growing, and the natural ecological environment is severely damaged.
In view of the problems in iron drum packaging, it is imperative to improve the asphalt packaging!
Into the 90s, there are many people of insight in the country to explore the use of flexible packaging instead of iron drum packaging, due to large investment and technical difficulties and fell. In 1995, Hong Deren, the current general manager and senior engineer of Dalian Xinke Packaging Materials Co., Ltd., took a determined and courageous determination to change the backward appearance of asphalt packaging, and embarked on a difficult and long-term road to tackling problems. At that time, he was still the director of a small chemical plant. With more than 20 years of experience in the chemical industry, he started to develop asphalt soft packaging bags in a simple laboratory and two other engineers.
They first raised a part of their own funds for the purchase of raw materials and test equipment, and conducted hundreds of tests on key technologies such as heat-resistance, anti-adhesion, compounding, and bag structure in the production of flexible bags. In the face of difficulties, I went to colleges and universities to ask for advice, and finally broke through the difficult road. In 1996, the first hand-made asphalt soft pack came out. This bag is composed of two layers of kraft paper inside and outside, and a composite of degradable fiber mesh. The inner layer is coated with a release agent, and a special sealing tape is used on the bottom and bottom. The inspection department has determined that the indicators such as anti-adhesion, strength, and heat resistance all meet relevant standards. The bags below 50°C can be peeled off from the asphalt.
The sample was taken out, followed by the production equipment problem. Once, Henderson went to a machine factory to seek cooperation in the production of asphalt bags. He told the director of the machinery plant that I have a production technology project for asphalt anti-adhesive composite bags. Can you cooperate with me to develop equipment? The director told Hong Deren that you are kidding. Your bag can fill more than 200 degrees of asphalt, and it can make asphalt and paper bags sticky.
In order to convince the director, Hundren Ren came to the factory with paper and adhesives for the second time. He made a bag on the spot and conducted a filling and peeling demonstration. The director was very moved and finally agreed to both sides. Jointly developed equipment, in 1998, the prototype of the first asphalt soft packaging bag production line was born.
The initial success did not give Henderson and his partners a sigh of relief, because they knew that a production line had to invest tens of millions of yuan from coating, compounding, bagging, sealing, and filling, and now they have reached a point where they are at a dead end. Now. One Japanese businessman learned of the results of Hung Deren's development and proposed to take $1 million to purchase this technology. However, Hung Deren did not agree. He said that this result is a result of the Chinese and must be promoted by us.
Faced with the troubled Hong Deren, his wife said that if you have a factory manager and you do not have diabetes, why should you ask for it? For the kindness advice of your lover, Hung De-ren doesn’t care, and what makes him most sad is still Unable to afford the tuition for the two children who went to school, Hung De-jen felt for the first time in his life that he was sorry for children, and money was too important for them.
When Hong Tehren’s scientific research achievements were plunged into financial troubles, Mr. Li Chuanhong, chairman of Dalian Jiuji Group and a well-known Liaoning entrepreneur, learned of this situation. Through his friend's understanding of the future of Hung De-ren's people and projects, he decided to help Henderson. He found out that Hung De-jen said that I look for your product, look for you, and let's do it one by one. I will support you financially!
In the face of Li Chuanhong, a Bole's mind, visionary brains and the strength of the 99 Group, Chairman Li, in particular, cherished talents and scientific and technological achievements, deeply touching the hearts of the people of Hongde. He agreed to invest his own achievements in the joint venture with the 99 Group to develop asphalt soft packaging bags. In 1999, Dalian Xinke Packaging Materials Co., Ltd. was established. The company has invested more than 40 million yuan, built a modern factory. A computer-controlled production line with an annual output of 20 million pieces of environment-friendly asphalt soft packaging bags is in operation, with an annual output value of 120 million yuan. Asphalt flexible packaging bag structure, material, shape, and sealing tape, composite agent, anti-adhesive agent and other achievements were approved by the State Intellectual Property Office as a national patent, which also fills the gap in the world a blank. This year, the company was confirmed as a high-tech enterprise by the Dalian Municipal Government. In 1999, the Asphalt Flexible Packaging Project was also included in the National Spark Program.
Experts at the provincial scientific and technological achievements appraisal meeting organized in August this year unanimously agreed that the environment-friendly asphalt soft packs produced by Dalian Xinke Packaging Materials Co., Ltd. have four characteristics:
1. Environmental protection. The materials used in this bag are kraft paper and fiber, anti-adhesion agents, and compounding agents. All of them are degradable and can be recycled. They do not cause any pollution to the environment and are called green packaging.
2. Good heat resistance and anti-adhesion. It was determined that the bag can be filled with asphalt below 280°C to fully satisfy the production conditions of asphalt. At the same time, due to the anti-adhesion of the bag, the bitumen can be separated from the package at a temperature below 50° C., and it will not cause bitumen sticking and residue.
3. Easy to transport. With the new flexible bags, a 60-ton wagon can be coded to 20 layers without damage.
4. Save on packaging fees. If iron drums are used, 6 iron drums per ton of bitumen are required. For example, at 30 yuan per old drum, the packing fee per ton of asphalt is 180 yuan, and the packaging fee per ton for flexible bags is only 150 yuan.
The news of Dalian Xinke Packaging Materials Co., Ltd.'s development and production of environment-friendly asphalt soft packaging bags has attracted great interest from domestic and foreign customers. Many merchants from other countries sent people to negotiate. At present, the products have entered the United States, Iran, Saudi Arabia, France and other countries as well as domestic major oil refineries.
The products sell well, and the company pays more attention to quality management. Recently, Dalian Shinke's asphalt soft packaging bags, anti-sticking agents and other products have passed ISO9002 quality certification, and the company's production has entered a scientific, standardized operation track.
In the face of market demand and development, the company's general manager, Hong Deren, said: The demand for environment-friendly asphalt soft packaging bags is very large. Next we are ready to cooperate with domestic and foreign manufacturers who are interested in asphalt packaging production and establish several branch companies to expand production scale.
