1. Girazi rinodziya
Girazi rakapfava chaizvoizvo rudzi rwegirazi rakapfava. Kuti girazi riwedzere kusimba, nzira dzemakemikari kana dzepanyama dzinowanzo shandiswa kugadzira kumanikidzwa pamusoro pegirazi. Kana girazi riine simba rekunze, rinotanga ragadzirisa kumanikidzwa kwepamusoro, nokudaro richivandudza kugona kwekutakura uye kuwedzera kusimba kwemhepo, kuramba mamiriro ekunze uye kuramba kuputika kwegirazi pacharo.
2. Girazi rinodzivirira kupisa
Girazi rekudzivirira kupisa rakagadzirwa nevaAmerica muna 1865. Rinosungirwa kubatanidza mipendero miviri yegirazi kana kupfuura pamwe chete, kugadzira gasi rakaoma rakamira pakati pemagirazi, uye kuva nekushanda kwakaringana kwevacuum. Rinoshandisa namatidziro ine simba rakawanda uye yakasimba yemhepo kuti ribatanidze jira regirazi nefuremu yealuminium alloy ine desiccant. Mazhinji acho anogadzirwa nemafekitori makuru. Hapana mavara, mvura, uye condensation pakati, Rine simba rakanaka rekupisa uye kudzikamisa ruzha.
3. Girazi rakacheneswa
Girazi rakakanyiwa rinogadzirwa nezvidimbu zviviri kana kupfuura zvegirazi rinoyangarara rakasungirirwa nePVB (polyvinylbutyraldehyde) adhesive film, rakadzvanywa nekupisa rinodzvanywa uye rinoburitswa zvakanyanya sezvinobvira, robva raiswa mu autoclave kuti rinyungudise mweya mudiki wasara mufirimu rinonamira pasi pekupisa kwakanyanya uye kumanikidzwa. Iye zvino, kune mhando itsva yefurnace, iyo inogona kugadzirisa firimu rekunze reEVA uye kupedzisa maitiro ekunamira kuburikidza nekupomba vacuum inodziya zvakanyanya mufurnace. Vanhu vanogona kusarudza nzira yakakodzera zvichienderana nebhajeti ravo, nzvimbo uye zvinodiwa zvekubuda. Zvichienzaniswa nemamwe magirazi, girazi rakakanyiwa rine hunhu hwekudzivirira kuvhunduka, kudzivirira kuba, kudzivirira mabara uye kudzivirira kuputika. Kana girazi rakakanyiwa raputsika, hariwanzo kupararira nekuda kwekunamira, uye kuchengetedzeka kwacho kwakanyanya.
Simba regirazi rakajairika rakaiswa laminated harisi rakakwirira, iro rakafanana neregirazi rakajairika rine chidimbu chimwe chete. Girazi rakaiswa laminated rine simba uye kushanda kwakachengeteka. Rinowanzoshandiswa muzvikamu zvemukati, mabhodhi efenzi, pasi pechikuva uye madziro emaketeni ane nzvimbo huru.
Parizvino, chitofu cheFangding chinonamira chinogamuchirwa nevanhu vakawanda nekuda kwenzvimbo yacho diki, mari shoma yekudyara, mhando yepamusoro uye goho guru.
