Girazi rekudzivirira kupisa rakagadzirwa muna 1865. Girazi rekudzivirira kupisa ndiro chinhu chekuvaka chine hunyoro hwakanaka, hunyoro hunochengetedza ruzha, hwakanaka uye hunoshanda, uye rinogona kuderedza huremu hwechivako. Rakagadzirwa negirazi rekudzivirira ruzha rinoshandisa magirazi maviri (kana matatu) richishandisa namatidziro yakasimba uye ine gasi rakawanda rinonamira girazi rinobatana nefuremu yealuminium alloy ine desiccant.
Chisimbiso chealuminium chine migero miviri
Chinotsigira aluminium spacer uye chakaparadzaniswa nezvidimbu zviviri zvegirazi zvakaenzana, aluminium spacer yakazadzwa negirazi rekudzivirira kupisa molecular sieve (particles) desiccant, kuti igadzire nzvimbo yekuvhara pakati pezvikamu zvegirazi.
Sefa yegirazi inochengetedza ngura inogona kunwisa mvura nezvinhu zvakasara zve organic zviri mukati mayo, izvo zvinoita kuti girazi rinochengetedza ngura rirambe rakachena uye richijeka kunyangwe patembiricha yakaderera, uye zvakare inogona kuyera musiyano wakasimba wekumanikidzwa kwemukati nekunze kunokonzerwa nekuchinja kukuru kwetembiricha. Sefa yegirazi inochengetedza ngura inogadzirisawo dambudziko rekukanganiswa nekupwanywa kunokonzerwa nekuwedzera kana kupfupika kwegirazi, uye kuwedzera hupenyu hwebasa regirazi rinochengetedza ngura.
Kushandiswa kwemusefa wegirazi unochengetedza girazi:
1) Kuomesa: kunyudza mvura kubva mugirazi risina chinhu.
2) Kudzivirira chando.
3) Kuchenesa: kunyudza guruva riri mumhepo.
4) zvakatipoteredza: zvinogona kudzokororwa, zvisingakuvadzi zvakatipoteredza
Chisimbiso chemhando ye "strip-type" chinoumbwa ne "namira"
Mutsetse wekudzivirira girazi muunganidzwa webasa re spacer nekutsigira frame yearuminiyamu, basa rekuomesa re glass molecular sieve (hupfu), basa rekuvhara butyl glue, uye basa rekuvaka re polysulfide glue, mutsetse wekudzivirira girazi unogona kukotama kuita chero chimiro woiswa pagirazi.
Zvigadzirwa zvine chekuita nazvo: JZ-ZIG molecular sefa, JZ-AZ molecular sefa
