Development of domestic pulp molding profile and analysis - Paper, pulp, molding - paper industry  


a foreign pulp overview of molding paper has become the world's major industrial industries. various paper and paper products deep into all aspects of people's lives, products are also able to develop such an environment, some developed countries pulp than 80 years. at present, france, the united states, japan, canada, iceland, britain, denmark, singapore, the netherlands and other countries of the industry already have a considerable scale.
in the u.s., basically paper products paper , approximately 450,000 tons of paper annually, from 1994 to 40% annual growth rate in 2000 has increased to 810,000 tons. since 1989, the u.s. plants producing about 600 pulp, paper and cardboard and related products. among them, 200 are basically using waste paper as raw material, another 300 in the production process 50% of the use of waste paper. the huge demand for packaging, has made it the third largest consumer recycled paper industry. second, the development of characteristics of the foreign 1. broad applications. such as the automotive industry, electronics, hardware, consumer goods, medical equipment, household goods, office products, paper products have even applied to sales packaging. 2. using computer-aided design. molded pulp products, three-dimensional computer model of software design, such as pro / engineer, solid? works, etc. designed to model the data file, you can use rapid prototyping and direct manufacturing mold prototype products. data files can be transferred to manufacturing software mastercam, direct cnc machining centers in touch with processing. and this technology is only for individual companies to control our country. 3. product design standardization, modularity. in the product, the mold cost is one of the important costs. foreign manufacturers that design applications in the products, when wide application, general good. for example, the flute-like general-purpose liner, protectors, separators, etc., because the large volume of production, mold utilization is high, simple design, molds amortized cost will be greatly reduced. 4. advanced production equipment and technology is reasonable. relative our country, which is characterized by pressure drying technology, direct compression molding, no oven, energy consumption greatly reduced; machine automation is very high, almost completely automated, saving energy and labor. iii overview of the domestic pulp development in china in recent 20 years. since the 80s of last century, hunan, beijing, shandong, jiangsu and the introduction of foreign production line for the production of eggs tray . plant in hunan in 1984, more than 1,000 million yuan investment from france to introduce a rotating drum automatic production line mainly used for the production of egg trays, this is the beginning . the late 80s, china started its own line of paper students. in 1988, china developed the first domestically produced pulp molding production line, mainly egg tray, beer tray, fruit care, the products a single, lower end. 90 years from the last century, molded pulp products used for packaging agricultural products, home appliances, electronics, instruments and other products.
