Kushandiswa kwePolycold kuteya mhute yemvura ipfungwa yakagadziridzwa naDale Meissner mu1970s senzira yekumhanyisa kubuda kwevacuum mukamuri uye kuderedza kudzvanywa kwechigadziko chekuwedzera vacuum coating.Mune evacuation system, unogona kubvisa mamorekuru egasi kubva mukamuri kana, kana iri mhute yemvura, shandura mamiriro egasi nekukonesa (kuteya) mamorekuru emvura pamhepo inotonhora.
dzimwe nheyo dzesainzi
Kana iyo kamuri inopombwa kubva mumhepo, pakati ~ 10-3 kusvika ~ 10-8 Torr, 65% kusvika 95% yemamorekuru ari mukamuri imhute yemvura.Pese apo vacuum system inovhurwa kumhepo, mukati mekamuri yekamuri ichafukidzwa nedhiri mushure mechikamu chemvura mamorekuru.Ukobvu hwechitubu ichi huchaenderana nehunyoro hwemhepo, exposure history, etc. Sezvo vacuum pressure iri mukamuri inodzikira, mhute yemvura iyi inoburitswa kubva kumadziro nepamusoro pekamuri, iyo inofanira kubva yapombwa kana kuunganidzwa. kure kure.Deredza kudzvinyirira mukamuri.
Mechanical misungo senge XIEYI CRYOCHILLER inoshandisa firiji kutonhodza simbi isina tsvina kana coils yemhangura mukamuri.Kugona kweiyi coil kuteya mhute yemvura kunoenderana zvakanyanya nehuwandu hwe cryogenic inotonhorera nzvimbo mukamuri.Sezvo mhute yemvura ichiburitswa kubva kumadziro kana dzimwe nzvimbo dzemukati dzekamuri, dzinofanirwa kupombwa kana kuvharirwa kuti dziwedzere kuderedza kudzvanywa kwevacuum mukamuri.Kana iwe ukawedzera huwandu hwemakoiri mukamuri, kugona kubata mvura mhute mamorekuru kunowedzera pavanenge "bounce" kutenderedza kamuri.
mukupedzisa
Iyo XIEYI CRYO CHILLER yakakosha kukurumidza kuburitsa vacuum makamuri ekugadzira maapplication.Pamusoro pekumhanyisa kubviswa kwemamorekuru emhute yemvura mukamuri, zvakare inoderedza vacuum base pressure uye inovandudza kunaka kwevacuum coatings mune akawanda maapplication.Kushandisa yakaenzana saizi XIEYI Mvura vapor pombi kuwedzera nzvimbo yemhangura kana simbi isina simbi coils inogona kuwedzera goho.
