1 The proposal of the project 1.1 Product Overview: Paper fiber molded tableware is a disposable catering container made of food packaging paper or pulp as the main raw material, through stamping or molding process. Compared with polystyrene (EPS) foam plastic tableware, which is still dominant in the market today, it has the obvious advantages of no toxic side effects to the human body during production and use, and can be naturally degraded after being discarded. Thus, the tableware is in the 20th century. After the 80's came out, it immediately swept the world, and some developed countries' products have entered the fourth generation. China's research and development of paper fiber cutlery began in the early 1990s, and its promotion prospects have been promising.
1.2 Development Status: Due to the current high manufacturing cost of paper fiber molded tableware itself, the unsatisfactory product quality, small-scale dispersion of production scale, combined with externally related regulatory construction lag, lack of supporting funds and immature consumer markets, etc. This has made this cross-century star of green products fail to effectively occupy the domestic market, to assume the historical mission that society has already high hopes of eradicating "white pollution", and even shakes people's confidence in their development. Looking at many of the above constraints, the most fundamental issue is its own problems. The fatal ones are that its scale of production and volume cannot go up, resulting in cost and price failures.
1.3 Conclusion: In summary, whether the unit production and total volume of domestic paper fiber cutlery can be increased to above the economic volume, form economies of scale, affect the survival of this product, but also related to the sustainable development of the tableware industry. The only correct way to solve this problem is to study large-scale production technologies and develop new series of products.
2 Research content and main ideas 2.1 Mass production technology:
2.1.1 In the manufacturing process, the wet method is formed into a dry method. That is, paper pulp molding was changed to paper powder molding.
2.1.2 Change the single machine vertical reciprocating molding equipment on the manufacturing equipment to the assembly line plane rotary wheel molding equipment. Although this improvement has increased the absolute cost of equipment investment at one time, it has also doubled the production capacity of the equipment. Its input-output cost, ie relative cost, is much lower than that of stand-alone equipment. The one-off molding quantity and speed of the equipment has always been the "knock neck" process that restricts its production capacity.
2.1.3 Change the single-piece mold to the combined mold on the forming mold, that is, a plurality of units can be arranged on a single mold, which not only saves the unit mold consumables, but also increases the number of one-time molding.
2.1.4 Drying on drying equipments Drying for tunnel dryers. Drying in stand-alone production often uses mold heating to dry at the same time in the form of a (complete) mold. It takes a long time and the batch size is small, and the tunnel kiln drying can be used instead. Increase batch and speed.
2.1.5 In the sterilization process, the heat sterilization is changed to ultraviolet tunnel sterilization. This device can be installed after the drying process and before the packaging process.
2.1.6 Manual and semi-automatic manual and semi-automatic operations are integrated in the operation and computer control is introduced. From the materials to the ingredients, molding, finishing, drying, sterilization, packaging and transfer of all processes between the use of automated assembly line equipment, which can reduce the number of operators, improve the manufacturing speed.
2.1.7 The current key or relative difficulty of the technology is 3 points: First, it is still an additive problem, because there are 3 points in the dry method: First, it is still an additive problem, because dry process additives should not only have wet process additives. In addition to its waterproof, oil-proof, temperature-resistant and non-toxic functions, it must also be emphasized that it should have a solidifying function. Otherwise, how to form a scattered sand. The second is the material transfer technology. To ensure that the paper powder particles are evenly distributed between the mold gaps, this is not a problem for the fluid-like pulp in the wet method, but it is for the paper powder that is solid. Problem.
2.2 Series Product Development:
2.2.1 Develop new varieties and specifications. Existing box-shaped, bowl-shaped cutlery can be deformed in appearance and specifications, such as covered, uncovered, large, medium, and small capacity. In addition, dishes such as plates, dishes, cups, pots, and bowls can be developed, and different specifications can be added. In addition to white in color, color or painted can also be considered to satisfy people's consumer habits. , consumer psychology and consumer demand. It can be imagined that on the table in the near future, disposable "full-paper" paper cutlery including a paper table, a paper napkin, chopsticks, and a paper spoon can be included.
2.2.2 Formulate standards for series products, formulate technical standards in accordance with product varieties and specifications, and make them serialized and standardized. Can first engage in corporate standards, and then engage in industry standards, national standards or adopt international standards and foreign advanced standards.
2.2.3 The key to this technology at present is the development of new product molds, because each new product must be developed for each product with a different variety and different specifications. It is almost impossible to develop a universal universal mold.
3 Project Performance Prediction 3.1 Social Effects: If the project is successfully developed and timely promoted, it can cure white pollution caused by domestic foam plastic tableware in 3 to 5 years, promote the sustainable development of China's tableware industry, and reduce the production process of foam plastic products. The Freon is responsible for the destruction of the atmospheric ozone layer, fulfilling China's obligations as a party to the Montreal International Convention, improving the people's lives and living environment, and improving people's dietary hygiene and health.
3.2 Economic effects: China has a population of 1.3 billion. Currently, the domestic consumer demand for all kinds of paper tableware is 10 billion pieces/year, and it is predicted that it can be turned 1-2 times within 5 years to reach 200 to 40 billion pieces/year. However, 150 to 300 pieces/year, less than one a day. If we consider the increase in the number of inbound tourism and the export to neighboring countries in South Asia and Southeast Asia, the potential of the consumer market is huge, which is the highest in the world. According to the above estimation alone, if large-scale production technology is used, and a series of new product developments are carried out, each integrated cost reduction will be 0.1 yuan or more, and the country will be able to increase direct profits by 2-4 billion yuan each year.
