The reporter learned that Guangxi is rich in rare earth resources and is a large province with large reserves of ionic rare earths in the south. Compared to the provinces of Jiangxi and Guangdong that have been developed in the past 30 years, Guangxi has not received large-scale development of rare earths, which can be described as rare earth resources. "Virgo." Guangxi Guangxi Nonferrous Metals Group Co., Ltd. was established in 2008 to unify and develop domestic nonferrous metal resources including rare earths.
The Guangxi Zhuang Autonomous Regional Party Committee's Party Committee, Guo Shengzheng, said that Guangxi has a unique advantage in terms of rare earth resources. The proven reserves of rare earth metal oxides are 1.1 million tons, and they are high-value ionic rare earths. The mining conditions are also very good. In the rare earth separation, magnetic materials, rare earth equipment production and other aspects also have a certain basis, these have created very good conditions for the cooperation between the two sides. He said that Chinalco is a large-scale central enterprise with strong financial strength and advanced management experience. The Beijing Non-ferrous Metal Research Institute has strong research strength in rare earths. Trilateral cooperation can achieve strong alliances and complementary advantages, and it will be used for rare earth industries in Guangxi and even China. Bigger and stronger have a positive impact.
Xiong Weiping, general manager of China Aluminum Corporation, said that at present, China's rare earth industry is facing a very good opportunity for development, Guangxi's development of rare earth industry has regional advantages and economic advantages, and resources are very good protection, great potential, is conducive to achieving a "high starting point, "High standards, high quality" goals. The establishment of the company is an important measure for the three parties to give full play to their advantages in the development of rare earth resources and research and development of rare earth products, and to jointly build a complete rare earth industrial chain with core competitiveness and a rare earth industrial park in southern China in Guangxi.
Xiong Weiping said that Chinalco actively participated in the implementation of the adjustment and integration of rare earth industry structure in accordance with the national rare earth industrial policy requirements, and promoted the mid-to-high end development of the middle and lower reaches of the rare earth industry through the industrialization of technological achievements; through the application of new technologies, the promotion of rare earth resources Mining and smelting separation technology upgrade, the formation of "less mining, more revenue, subdivision, refining, high value" of the industrial route, and strive to create an inherent advantage of the rare earth industry can participate in the global rare earth industry competition.
According to reports, China Aluminum Guangxi Nonferrous Rare Earth Development Co., Ltd. is a state-owned wholly-owned enterprise integrating rare earth mineral resources exploration, smelting and separation, deep processing, and rare earth research and trade. The registered capital of the company is 500 million yuan. The business scope is mainly the investment in rare earth mineral rights, deep processing of rare earth products, and research and development, production and sales of new products. The company will base itself on Guangxi, persist in co-ordinating domestic and international markets and two resources, actively carry out international cooperation, and take advantage of the special geographical advantages of Guangxi-ASEAN Bridgehead to build the company into an internationally influential rare earth enterprise. The company will also vigorously develop rare earth downstream industries, actively build China Southern Rare Earth Industry Park, and build a complete rare earth industrial chain with core competitiveness.
The material of the sandwich panel directly affects the later use. Sandwich panels are the main building materials for Prefabricated House and Steel Structure Warehouse. If you want to choose high-quality panels, you must have an understanding of their basic quality. There are many types of boards on the market, and their core materials, steel plates, adhesives, etc. are different, and the quality will also be affected. So how to judge its pros and cons?
check edge
Because the sandwich panel has several layers, it is difficult to judge its internal quality from the surface. Therefore, it is still necessary to observe its exposed edges first, and it is necessary to pay attention to whether its cross-section is clean and ensure that it is tight. If there are problems such as graying and impurities, then there must be problems in quality, so it is still necessary to do a good job of cross-sectional inspection.
Tap to hear the sound
If it is a relatively good board, you can simply tap it with your fingers. If the sound is a crisp metallic sound, then it is a relatively good board. The fire rating of the Rock Wool Sandwich Panel is Class A, and the fire rating of the polyurethane sandwich panel and Eps Sandwich Panel is B1.
Note the thickness
The thickness of the sandwich panel directly affects the long-term use in the later period. It is necessary to observe the substrate, peritoneum, etc., especially the thickness and quality of the coating, which we cannot ignore. It is necessary to choose a plate with a relatively thick coating and guaranteed quality. Generally, the thickness of the substrate should be about 0.4-0.8MM. If you see the real thing, you should also measure it. The thickness of the finished product is 50mm, 75mm, 100mm, 150mm. The bulk density of the core material is also an important link that affects the quality.
certificate
In fact, as long as it can cooperate with regular manufacturers, the plates sold by the manufacturers need to go through various inspections, and the quality must meet the regulations. Therefore, when purchasing, you can directly check whether it has a certificate of conformity. If you choose a plate from a regular manufacturer, you can not only enjoy a preferential price for direct sales from the manufacturer, but also enjoy good after-sales service.
Now there are many manufacturers supplying plates, and the market quotations and quality of each manufacturer are also different, so it is still necessary to do a good job of quality comparison and price measurement. It is suggested that when purchasing sandwich panels, one must pay attention to its specific quality, and compare the quality of the actual products in order to select high-quality panels.
The China National Aluminum Corporation Guangxi Nonferrous Metal Rare Earth Development Co., Ltd., jointly established by China Aluminum Corporation, Guangxi Nonferrous Metals Group Co., Ltd. and Youzhe Rare Earth New Materials Co., Ltd., was established in Nanning and will build a complete rare earth industrial chain with core competitiveness. We will strive to invest 2 billion yuan in three years, achieve a sales revenue of 3.5 billion yuan, profits and taxes of 800 million yuan, and the goal of listing five years or so.
