Iyo mudziyo unowanzogadzirwa kubva kune yakakwirira-mhando zvinhu sePolyurethane foam kana vacuum-insured mapanera ekutsvaira
Iyi nhevedzano yezvigadzirwa ine vhoriyamu ine mwero uye inopa sarudzo yakanaka kune vashandisi vanofanirwa kuchengeta masampulogical samples kana mvura nitrogen mumba kwenguva yakareba pasi pemamiriro ezvinhu akaiswa pasi pemamiriro ezvinhu.
Nheyo yekushanda yeiyo yemvura nitrogen yekuchengetedza tank ndeye liquefy nitrogen uye chengetedza iyo mutangi wemukati.
Iyo yemvura nitrogen yekuchengetedza tangi inoenderana neyekunze tangi muviri, muviri wemukati tangi, layer layer, iyo level level kugeza, kumanikidza Gauge uye vheji yekuchengetedza.
Iyo yemvura nitrogen yekuchengetedza tangi ndeye yakapetwa kaviri-deyer yakagadziriswa vacuum poda inonzi yekuchengetedza tangi. Iyo tangi yemukati yakagadzirwa nesimbi isina tsvina, uye tangi rekunze rakagadzirwa neQ235b kana Q345r.
Zvakawanda zvigadzirwa, kuchengetedza kwenguva refu mufiriji kunotungamira kune zvigadzirwa zvemhando yechigadzirwa, asi semuenzaniso, michero yakadai seBhanana
