Patented technology of bone nails suitable for hot melt implantation into cervical correction or diseased bone
The global market value of orthopaedic equipment is estimated to grow from $26.3 billion in 2012 to $38.1 billion in 2019, with an average annual growth rate of 5.7%. The global spine product market is expected to grow from 6.45 billion US dollars in 2012 to 10.65 billion US dollars in 2019, with an average compound annual growth rate of 8.1%. There are about 40 million fracture patients in China every year, and the annual demand for metal internal fixation materials exceeds 3 million. Fractures occur every three seconds worldwide. (Data source: Kalorama Information 2015/Metal Center MII collation) Medical metal materials are widely used in clinic because of their high strength, good toughness, bending fatigue strength and excellent processing and forming properties. Traditional medical metal materials, such as 316L stainless steel, Co-Cr alloy, titanium and titanium alloy, are all bioinert materials. They can not degrade by themselves after implantation into human body. They need to be removed by second operation, which increases the pain of patients and the burden of medical expenses. Biotoxic metal ions and particles formed by wear or corrosion of these inert materials in vivo can cause allergic or inflammatory reactions in surrounding tissues and reduce the biocompatibility of materials. Therefore, based on the above, it is imperative to develop biodegradable medical magnesium metal materials.
The problem of rapid degradation of PLA coated by Guangyu high strength pure magnesium bone nail
The main drawback of traditional magnesium bone nail is that "the degradation speed is too fast". Before the bone hyperplasia, the magnesium bone nail has been degraded and ablated. Since 2014, Taiwan Guangyu Technology Co., Ltd. has cooperated with the Taiwan metal center to carry out experiments. It uses high-purity magnesium materials to manufacture non-toxic magnesium bone nails and "encapsulates biodegradable polymer materials" to slow down the rapid degradation rate of traditional magnesium bone nails, and has successively obtained invention and utility model patents.
The bracelet of Poseidon_Bracelet aluminum anode for submarine pipeline cast by MACH
Bracelet type aluminum alloy sacrificial anode is mainly used for anticorrosion of "submarine pipeline". As the name implies, "Bangle type" uses semicircular bracelet type anode body (including semicircular ring anode body and iron core) to fasten the submarine pipeline "like a bracelet". The iron core runs through the semicircular ring anode body, and its two ends pass through the semicircular ring anode body. The key to the casting of this product lies in the design and manufacture of the die structure. After melting according to the casting process, the semi shell molding with the thickness of 50mm, the length of 350mm ~ 500mm depending on the design and the gross weight of steel core ranging from 97.6kg to 221kg is carried out with the mould After casting, the upper and lower half shells of each anode block need to be coated with epoxy resin shielding coating with thickness > 300 μ m. The production standard is dnvgl-rp-f103 2016 ISO 15589-2:2004.

The best tool for measuring slag in front of the furnace __MACH patent impurity detector
"The world of magnesium alloys, there is no impurity!!" Since the company launched its magnesium industry in 2004, it has developed a “all-round metal impurity detector” from the magnesium alloy new material research center team. It uses quantitative analysis, fast and effective detection methods, and sampling before melting. The content, size and location of the impurities in the pot are measured, and the "in-furnace detection and inclusion" can be achieved before the start of the die-casting machine. The industry generally only knows that the material can not be mixed, but it cannot "immediately detect" impurities. embarrassment.
Method for determining particle size composition distribution of magnesium alloy particles
MACH Technology Document No.: MACH/ZCH-ZG-027 Scope of application: Magnesium alloy particles obtained by milling method for semi-solid die casting products. Testing equipment: Φ200 standard inspection sieve machine, screen mesh specification: stainless steel woven mesh, a total of 7 layers, sampling method to implement GB/T5314-2011 "Powder metallurgy powder sampling method". Samples were taken with a sampling spatula and a sampling needle to measure the particle size distribution and chemical composition of each barrel, bag, upper, middle and lower parts. The sample taken is carefully mixed uniformly, and the average sample is taken out, and the mass thereof should be not less than 1000 g. ....... If only the particle size distribution does not meet the standard requirements, the team can rescreen the particles in this batch. The method of re-screening the particles is still carried out according to the above method. The qualified report is put into the warehouse. If the batch is unqualified, the batch is judged as waste and will not be re-screened.
Japan jsw thixotropic injection molding machine favorite __ magnesium particle cutting machine
The Thixomolding type is a revolutionary magnesium alloy forming method that cares for the environment. The thixoforming type is a method of injection molding a magnesium alloy in a semi-molten state (thixotropic melt). The magnesium alloy is injected into the mold by heating and heating the magnesium alloy particles in the barrel of the molding machine and using the screw in the barrel for metering and conveying. The magnesium alloy particles produced by MACH are the favorite of Japan jsw thixotropic injection molding machine!
Recycling magnesium waste residue combined with citric acid to produce hydrogen energy (2)
The recovery rate of refined magnesium in the production of magnesium metal is about 94%, that is, the content of magnesium in the refined slag is about 6% of the amount of magnesium produced, and the recovery rate of refining for crystallized and small crystalline magnesium. Only about 80%, the magnesium content in the refining slag is as high as 20%. If the magnesium refining slag with high magnesium content is not used well, it is not only a waste of resources, but also brings us a living environment. Serious destruction. How to use refining slag has become a matter of great concern to the industry.
