On April 23, the first aramid honeycomb composite material was successfully put on the line in the production workshop of Hedali Composite Materials Co., Ltd., located in the Dianjun District of Yichang City, Hubei Province, and was about to “ride†the “flight†of the domestic large aircraft. China Southern Airlines, Hafei, Xifei and other domestic aircraft manufacturers made special trips here to witness the official launch of the largest domestic aerospace compound material production base. It is reported that in the future, the base will provide manufacturing materials for R&D-made large aircraft.
According to Yi Yong, Chairman of Yichang and Dali Composite Materials Co., Ltd., Aramid honeycomb composite material is a new type of high-tech bionic new material. Besides its excellent properties such as flame-retardant insulation and anti-corrosion and environmental protection, it also has the features of light weight and high strength. Its unit weight is 9 times stronger than high-quality steel and is an important material for domestic aircraft manufacturing. At the same time, the material is also widely used in high-speed trains, rowing boats and other fields. In May 2012, after completing the second phase of investment, the company's average annual output value will reach 1.2 billion yuan, becoming the leading domestic honeycomb composite material company and Asia's largest Kevlar composites research and development center.
The total investment of Dalit Aramid Honeycomb Composites project is 133 million yuan, and annual production of aramid honeycomb is 480,000 square meters. As the largest domestic research and development base for aramid honeycomb production, its production has attracted the attention of domestic aviation companies and aircraft manufacturers. After only two years of hard work, Dali not only completed the basic construction of the aramid honeycomb project, but also overcomed many technical difficulties and built the largest Aramid honeycomb R&D production base in the country and even in Asia. The trial production is consistent with European and American standards. , China's largest size of aramid honeycomb composite materials. At present, he and Daly have cooperated with Changhe Aircraft Manufacturing Company and Hafei Company. On the day of production, Dali also signed supply orders with Xi'an Jiaye Aviation Technology Co., Ltd.
Aramid composites are hailed as diamonds on the crown of the world's materials, as well as carbon fibers and ultra-high-molecular-polyethylene fibers, and are also known as the world's three high-performance materials. In the field of military industry, aramid composite materials are widely used in high-performance structural parts and special electronic equipment for aircrafts, ships, tanks, missiles, and radars. In the civilian field, aramid composites are mainly used in high-performance structural parts for aerospace, aviation, high-speed trains and automobiles, high-end insulation materials for power grid engineering, and heat-insulating and flame-retardant materials for construction.
The non-clogging pump is a new type of energy-saving pulp pump. After practical use, it has the characteristics of high efficiency, no or less leakage, good anti-clogging, stable operation, high reliability and compact structure.
The non-clogging pump is a new type of energy-saving pulp pump. After practical use, it has the characteristics of high efficiency, no or less leakage, good anti-clogging, stable operation, high reliability and compact structure. It is mainly reflected in the following aspects: the semi-open or fully open impeller, the wear-resistant plate and the front side of the impeller are adjustable, the shaft seal is mainly mechanical seal, and high-precision bearings (D-grade accuracy) and high-quality shaft materials are selected. Therefore, the XWJ pulp pump is your ideal "good helper", and your success is also our constant pursuit.
