1. Vacuum thermal insulating material;

  • It will be configured as the tabular core that obtains by the duplexer that glass fiber mesh constitutes for using external cladding material to coat;

    And said external cladding material inside reduced pressure and the Vacuum thermal insulating material that forms;

    Glass fibre is used for said core, and said glass fibre carries out after the fibrosis, carries out chilling and reinforcement through the winding-up cooling air immediately;


    After core is compressed to 2000hPa, discharge repeatedly under the situation of operation of compression rapidly, the thickness of the core when compression strength reaches 1800hPa when compressing for the first time is as root thickness, and the compression strength under the said root thickness during the 2nd compression is more than 0.89 with the ratio of 1800hPa.
