hardware flow control. It is an ideal choice in the field of industrial automation.
Microspheres, one-thirtieth the diameter of a hair. In the mobile phone screen, one hundred microspheres are used per square millimeter to hold up
two glass panels, which is equivalent to a skeleton. Liquid crystal is poured into the gap between the two glass panels. Without it, the
LCD screen you”re staring at wouldn”t be manufactured. Without microspheres, chip production, food safety testing, disease diagnosis
, biopharmaceuticals, environmental monitoring… many industries would be in trouble. In the field of microelectronics alone, China imports
microspheres worth tens of billions of yuan every year. In 2017, mainland China”s LCD panel shipments accounted for 33% of the world”s total
, with an industry scale of approximately US$100 billion, ranking first in the world. However, only one or two Japanese companies in the world can
provide the key materials in the panel – spacer microspheres and conductive gold balls. These materials are also like chips, which are stuck in the neck.
twenty one”Without three key materials, it is difficult to commercialize fuel cells” (Science and Technology Daily, June 14)
Foreign fuel cell vehicles have achieved mass production, but my country”s vehicle fuel cells are still in the technology verification stage. The current
situation of vehicle fuel cells in my country is that there are almost no component manufacturers, no vehicle stack production companies,
and only a very small number of commercially operating fuel cell vehicles. A number of key materials determine the life and performance
of fuel cells. These materials are not completely absent in our country, and some laboratory results have even reached international standards.
However, without mass production lines, the fuel cell industry chain is still blocked. Key materials have long been dependent on foreign countries.
Once sales are banned, my country”s fuel cell industry will have no basic support.
