Freeze-dried ball, also known as freeze-dried bead, liquid nitrogen point ball, refers to the reagent/pharmaceutical liquid, through the professional precision trace pump point to liquid nitrogen, so that it in very short and very low temperature, quickly frozen into a uniform shape of the regular small solid ball, and then collected into the Xinshu freeze-dried equipment frozen storage. The freeze-dried bead technology can maintain the activity of enzymes/proteins, and the freeze-dried bead has a loose network structure and rapid redissolution. Freeze-dried beads technology can convert unstable chemical reagents into high-quality, stable, quantitative freeze-dried beads, which is especially convenient for drug storage and transportation, and is a popular technology

We maintain the view that ultra-thin VC will be a key cooling element for 5G smartphones in the next 2 to 3 years, and due to the uncertainty of high-end chip supply,
the contradiction between the performance of 5G smartphones and high power consumption heating may be intensified, or promote the demand for heat dissipation products.

VC soaking plate is a vacuum chamber with a fine structure on the inner wall, usually made of copper. The function is to reduce the diffusion thermal resistance between the heat source and the radiator,
and improve the efficiency of the radiator. The inner wall of the heat pipe is a layer of capillary structure, which is filled with liquid and vacuumed.
Installed in the heat source end we call the evaporation end, when the heat is released, the evaporation end of the internal liquid gasification, transferred to the other end of the lower pressure condensing end,
the condensing end is cold and condensed into water.

AF anti-fingerprint liquid, also known as AF vacuum coating pill, is a type of material, mainly used in touch screen display panels, optical glass, sapphire, ceramics,
plastics, mechanical metal parts, auto parts and other fields, has been widely used.

AF vacuum coated pill has the following characteristics:

Since its establishment, Ji kerr has continuously explored the field of lithium battery precision injection and has completed more than 20 invention patents.
Among them, ceramic variable pump, multi-head ceramic variable pump, non-pulsating constant flow pump, micro ceramic piston pump and so on
Ten years of hard work has made due contributions to promoting the localization of precision ceramic metering pumps and improving the overall level of domestic liquid injection equipment.
"Before the establishment of Ji kerr, domestic lithium battery companies mainly used Canada's Haiba pump and the United States IVEK ceramic pump,
in 2013 Ji kerr successfully launched a single-head ceramic injection pump, and with excellent performance and price, batch localization, to replace,
to promote the rapid localization of liquid injection equipment, farewell to foreign liquid injection pump neck."

Freeze-dried ball, is a feature of IVD in vitro diagnostic industry hot push, different from freeze-dried powder and freeze-dried block, is a new vacuum freeze-drying technology,
is the mixed active biological reagents through the Ji kerr liquid nitrogen point liquid freeze bead machine point liquid into liquid nitrogen to freeze into the size and weight of the ball required,
and freeze-dried machine vacuum freeze drying processing, to get smooth sphere-freeze-dried ball. The freeze-dried balls of collagen and polypeptide are processed by freeze-dried machines.

As more and more countries attach importance to environmental protection, new energy vehicles are being developed and promoted in more and more countries.
At the same time, the industry estimates that in 2015, the cumulative scrap of new energy vehicle batteries is about 20-40,000 tons.
The recycling of lithium-ion batteries for new energy vehicles has become a problem that cannot be ignored.

Southern Daily News (reporter/Peng Lin Chen Xiao) On March 13, the official website of the State Food and Drug Administration showed that the registration application of five new coronavirus antigen test products was approved. Together with the five approved for the first time, a total of 10 novel coronavirus antigen test products have been officially launched so far. Of the five products approved for the first time, two are produced by Guangdong companies, namely Shenzhen Huada Inyuan (a subsidiary of BGI) and Guangzhou Wanfu Biology.
