Recently, China Aluminum Guizhou Branch actively carried out technological innovation, through four steps to promote the "three-level confluence", realized the Bayer-sintering two process confluence technology innovation, and formed an improved combined process alumina production process technology. Relying on the previous step, the Bayer-sintered semen confluence is realized; in the second step, the desiliconization overflow of the sintering method and the dissolution of the dissolved ore pulp are realized; in the third step, the full confluence of the medium-pressure desiliconization slurry and the Bayer-dissolved pulp is realized; and the fourth step is to use The partial sintering method dissolves the crude liquid instead of the washing liquid, and is injected into the flash evaporation system of the high-pressure dissolution unit, and the flash liquid waste heat is used for the desiliconization of the crude liquid. At the same time, a series of innovative technological achievements with independent intellectual property rights were formed in the process of Bayer-Burn combined flow technology innovation. The first time in the world, the use of non-agitation columnar flow decomposition technology was innovative and achieved significant results.
Chinalco, as the first batch of “Innovative Enterprise Pilot Work Units†in the country, relies on independent research and development of Bayer alumina production technology, intensified sintering alumina production technology, and lime Bayer alumina production technology, in the alumina production field Promote independent technological innovation, carry out scientific research, expand the use of resources, and significantly reduce energy consumption. At present, the company's alumina production ranks second in the world, its output of primary aluminum is the third in the world, its output of aluminum processing materials is the fifth in the world, its aluminum processing capacity is in Asia, and it has international advanced level and independent intellectual property rights, capable of handling various grades of aluminum. Alumina production technology for earth minerals and aluminum electrolysis technology for 400kA large prebaked electrolytic cells. Alumina and electrolytic aluminum technology levels and equipment manufacturing levels have ranked among the best in the world.
At present, in the process of isolation and preparation of various stem cells from various tissue sources, Centrifuge Tubes with a volume of 15ml and 50ml are used.
It is one of the low-value consumables with high usage rate. It is generally installed on a dry foam rack with the package or in bulk. When used, it is taken out by the operator and placed on the plastic centrifuge tube rack in the ultra-clean workbench. The common centrifuge tube rack can only make the centrifuge tube stand upright. When transferring liquid or needing centrifugation, the operator should hold the centrifuge tube in the left and the night gun or aspirator in the right. If it is necessary to transfer a large amount of liquid reagents or perform gradient centrifugation operations, such as density gradient centrifugation to separate mononuclear cells, the operator needs to hold the centrifuge tube with the right hand for a long time and tilt the centrifuge tube, which often causes the operator's wrist joint pain. At the same time, it will also affect the liquid superposition effect, which will easily lead to the mixing of liquids of different densities, resulting in the failure of the experiment.
