Modern pulp and paper manufacturing equipment belonging to the technology-intensive than large equipment manufacturing industry, China's paper industry is to provide technology and equipment industries. And the relative phase of the development of China's paper industry should also generally experienced about 20 strategic adjustment period: led by the Government, along the "technology, digestion and absorption, and domestic production," in order to catch up with the main line, in spite of the many achievements , but technology and products with the world's advanced level there has been no narrowing of the gap between the number. Reflected in the imported equipment more dominant product is only sold to small and medium-sized pulp and paper mills. But in the meantime, the industry is brewing in the tremendous potential of the market, institutional change is driving the acceleration of technological progress.
So far from the end of the last century, the industrial structure of China's Paper period of rapid growth and huge market demand for pulp and paper manufacturing equipment to the high growth rate and with the technological advances by leaps and bounds. From 1998 to 2004, will continue the industry's national statistics: the total industrial output value (same price) average annual growth rate of 15.1%, an average annual growth rate of export delivery value of 39.2%, an average annual increase of the total profits of 28.6%, an average annual GDP labor productivity up 15.7 percent. The technological level of some products being near the international advanced level, and its ratio of performance to price advantages for some large-scale enterprises to use APP, beginning to show its international competitiveness. Why have such a big change? We believe that the following points should be deep thought, or even the whole of China's equipment manufacturing industry and draw some inspiration.
First of all, is to embark on a rapid and sustainable path of development and modernization of China's paper industry, the pulp and paper equipment in terms of quality and quantity has put forward higher requirements, in the intense market competition is always the driving force for industrial development.
Secondly, as the equipment manufacturing industry, as a technology-intensive and labor-intensive double feature, consisting mainly of consumer goods following the labor-intensive manufacturing sector, according to World industrial restructuring and the transfer of the law, to have their comparative advantage and the advantage of the , which is China's pulp and paper equipment manufacturing industry faces a period of strategic opportunities.
Thirdly, as the Health System Change variables play a decisive role. From the 1980s to the 1990s, mainly in the following two aspects of system changes for pulp and paper manufacturing equipment by leaps and bounds in the development of the removal of institutional barriers, and created a line with the rules of market economy in the context of globalization and enhance competitiveness The necessary conditions are fundamental conditions.
Over the past 10 years, China's pulp and paper manufacturing equipment have made spectacular technological advances, is now engaged in the pulp and paper equipment manufacturing industry there are about 500 enterprises, have developed into products of strong adaptability and technical complexity, variety wide variety of electrical and mechanical device, the combination of high-tech computer accessory products, and many products have been close to or even reach the international advanced level.
The purpose is to further ease the completion of the broken fiber follow-up to complete dissociation paper fibroblasts. Just use pulper to complete the full broken fiber solution is not appropriate, this may result in excessive damage to lower fiber and fiber strength, power consumption will make too big. Usually Deflaker pulp ease to complete the process, the ease of a common fiber separator, disk Refiner, high-frequency ease machines. Usually ease on the initial purification processes, and after the screening, in order to prevent some relief without impurities. Ease after the pulp is usually used to screen Cleaner and centrifugal further purification and screening, to remove impurities and excess slurry in water, so that the appropriate concentration of pulp, after all centrifugal slurry pond in abeyance screen.
