Vacuum Glass
Iyo Vacuum Insulated Glass pfungwa inouya kubva mukumisikidzwa nemisimboti yakafanana neDewar flask.
Iyo vacuum inobvisa kupisa kupisa pakati pemapepa maviri egirazi nekuda kwegaseous conduction uye convection, uye imwe kana maviri emukati magirazi masheets ane yakaderera-emittance coatings inoderedza kupisa kwemhepo kune yakaderera.VIG yekutanga yenyika yakagadziridzwa muna 1993 paYunivhesiti yeSydney, Australia.VIG inowana yakakwira yekupisa kupisa kupfuura yakajairwa insulating glazing (IG Unit).
Mabhenefiti Makuru eVIG
1) Thermal insulation
Iyo vacuum gap inoderedza zvakanyanya conduction uye convection, uye yakaderera-E coating inoderedza mwaranzi.Pepa rimwe chete regirazi repasi-E rinobvumira mamwe mwenje wechisikigo muchivako.Iyo tembiricha yeVIG glazing yakananga mukati iri padyo nekamuri tembiricha, iyo yakanyanya kugadzikana.
2) Kuvhara kwenzwi
Ruzha harugone kufambiswa muvacuum.VIG panes yakavandudza zvakanyanya acoustic attenuation kuita kwemahwindo nemafacade.VIG inogona kudzikisa zvirinani pakati uye yakaderera-frequency ruzha, senge traffic traffic uye hupenyu ruzha.
3) Yakareruka uye yakaonda
VIG yakatetepa kupfuura iyo IG unit ine mhepo nzvimbo panzvimbo ye 0.1-0.2 mm vacuum gap.Kana yakashandiswa kune chivako, hwindo rine VIG rakanyanya kutetepa uye rakareruka kupfuura iro rine IG unit.VIG iri nyore uye inobudirira kupfuura katatu-glazing kudzikisa U-factor yehwindo, kunyanya kune dzimba dzepasi uye zero-simba zvivakwa.Nezve kudzoreredza kwekuvaka uye kutsiva girazi, iyo yakaonda VIG inosarudzwa nevaridzi vezvivakwa zvekare, sezvo iine kushanda kwepamusoro, kuchengetedza simba, uye kusimba.
4) Hupenyu hurefu
Hupenyu hwedzidziso hweVIG hwedu makore makumi mashanu, uye hupenyu hunotarisirwa hunogona kusvika makore makumi matatu, huchisvika kuhupenyu hwemusuwo, hwindo, uye maketeni emadziro emadziro zvinhu.
