A hydraulic component that provides pressurized fluid for hydraulic transmission. It is a type of pump. Its function is to convert the mechanical energy of power machines (such as motors and internal combustion engines, etc.) into liquid pressure energy. There are many factors affecting the service life of the Hydraulic Pump, in addition to the pump itself design, manufacturing factors and some pump use related components (such as coupling, oil filter, etc.) selection, operation in the process of test run, etc. Hydraulic Pump Lift Pump Assy,Tractor Loader Hydraulic Pump,Farmtrac Hydraulic Pump,Tractor Hydraulic Pump YUHUAN CITY KANMEN DONGHAI AUTO PARTS FACTORY (GENERAL PARTNERSHIP) , https://www.donghaiqituo.com
Biodegradable plastic is a biomass-based resin produced using biotechnology. It is a type of new environmentally-friendly basic raw material that can be fully degraded to carbon dioxide and water. It can replace petroleum-based plastics, thereby reducing oil resources. Dependency. Experts believe that the status of biodegradable plastics should be higher than biofuels, biodiesel and other biomass fuels.
According to reports, the key technology development projects for industrialization of biodegradable plastics, which will be supported by the country, will mainly complete the 10,000-ton CO2-based plastics industrial production, the 10,000-ton-grade polylactic acid industrial production, and the 10,000-ton polyhydroxyalkanoates. Industrialization, production and application of 10,000-ton konjac glucomannan, development and application of biodegradable plastics for food packaging, medical evaluation of biodegradable plastics, and research and development of medical products. The overall goal of the project is to research and develop key technologies for the continuous industrial production of three types of typical biodegradable plastics, including carbon dioxide-based plastics, polylactic acid, and polyhydroxybutyrate, which have different temperature resistance properties, and establish industrialized demonstration production lines and the formation of Complete set of process packages; through the improvement of thermal and mechanical properties of biodegradable plastics, the preparation technology for biodegradable plastic special materials is formed, breakthroughs in key processing technologies for medical and food packaging and other products, and biodegradable plastics for medical and food packaging. Safety and life cycle to carry out systematic research, establish an evaluation system, promote the establishment of relevant national standards, accelerate the application of biodegradable plastic products on a large scale.
It is understood that the Changchun Yinghua Institute of the Chinese Academy of Sciences, the Institute of Chemistry of the Chinese Academy of Sciences (Beijing), the Shanghai Institute of Organic Chemistry, Nanjing University, Fudan University, and Zhejiang University have carried out a lot of work on biomass plastics and achieved industrialized technological achievements, but the cost The problem has always been the core of the development of the biomass plastics industry. Experts said that the main measures to reduce costs are two aspects, one is to reduce the cost of biomass raw materials, the second is to reduce costs through biochemical technology. These will be one of the focuses of scientific research in the future.
Recently, it was learned from the Materials Division of the High-tech Division of the Ministry of Science and Technology that "Key technologies for the industrialization of biodegradable plastics" have been listed as key projects in the National Science and Technology Support Plan for the "Eleventh Five-Year Plan" period. The state will allocate 30 million yuan to support relevant scientific research units to focus on the development of this technology. . The Ministry of Science and Technology requires the project to file 5 to 8 international patents within 3 years and apply for 12 to 16 Chinese invention patents.
