1. Pfupiso yegirazi rinodzivirira
Girazi rakaputirwa imhando yegirazi rinochengetedza simba rave richishandiswa zvakanyanya muzvivako zvemahofisi ebhizinesi, nzvimbo huru dzekutenga, zvivakwa zvekugara zvemarefu nezvimwe zvivakwa. Rine hunhu hwakanaka hwekudzivirira kupisa uye kudzivirira ruzha uye rakanaka uye rinoshanda. Girazi rakaputirwa rinoumbwa nezvidimbu zviviri (kana kupfuura) zvegirazi zvakabatana ne spacers. Kune mhando mbiri huru dzekuvhara: nzira ye strip uye nzira yekubatanidza glue. Parizvino, chisimbiso chakapetwa kaviri munzira yekubatanidza glue ndiyo inonyanya kushandiswa sealing structure. Chimiro chacho chakafanana nezviri kuratidzwa muMufananidzo 1: zvidimbu zviviri zvegirazi zvinoparadzaniswa ne spacers, uye butyl sealant inoshandiswa kuvhara spacer negirazi riri pamberi.Zadza mukati me spacer ne molecular sefa, uye vhara mukaha uri pakati pemucheto wegirazi nekunze kwe spacer ne secondary sealant.
Basa rechisimbiso chekutanga nderekudzivirira mhute yemvura kana gasi risina simba kuti ripinde nekubuda mugomba. Butyl sealant inowanzo shandiswa nekuti mwero wekufambiswa kwemvura negasi risina simba rebutyl sealant wakaderera zvikuru. Zvisinei, butyl sealant pachayo ine simba shoma rekubatanidza uye kusasimba kwakaderera, saka chimiro chose chinofanira kugadziriswa nechisimbiso chechipiri kuti chibatanidze magirazi nema spacers pamwe chete. Kana girazi rinodzivirira rava pasi pemutoro, jira rechisimbiso rinogona kuchengetedza mugumisiro wakanaka wekuvharwa. Panguva imwe chete, chimiro chose hachikanganisike.

2. Mhando dzezvimwe zvinovhara girazi
Kune mhando nhatu huru dzezvimwe zvinovhara girazi: polysulfide, polyurethane uye silicone. Tafura 1 inoratidza humwe hunhu hwemhando nhatu dzezvinovhara girazi mushure mekunge zvanyatsopora.
Tafura 1 Kuenzanisa kwehunhu hwekushanda kwemhando nhatu dzezvisimbiso zvechipiri zvegirazi rekudzivirira
Chakanakira polysulfide sealant ndechekuti ine utsi hwemvura hushoma uye argon gas transmittance patembiricha yemumba; chakashata ndechekuti ine mwero wepamusoro wekunyudzwa kwemvura.
Mwero wekupora kwemvura (modulus) uye elastic recovery rate zvinodzikira zvakanyanya sezvo tembiricha ichiwedzera, uye kufambiswa kwemvura nemhepo kunowedzerawo kana tembiricha yakakwira. Pamusoro pezvo, nekuda kwekusakwanisa kwayo kukwegura kweUV, kupiswa kweUV kwenguva refu kunokonzera kubviswa kwegum.
Chakanakira polyurethane sealant ndechekuti utsi hwayo hwemvura negasi reargon zvakaderera, uye utsi hwemvura hwakadererawo kana tembiricha yakakwira; chakashata ndechekuti haina simba rekudzivirira kukwegura kweUV.
Silicone sealant inoreva sealant ine polysiloxane sechinhu chikuru, chinonziwo agricultural production system silicone sealant. Polymer chain ye silicone sealant inonyanya kuumbwa neSi-O-Si, iyo yakabatana kuti igadzire chimiro cheSi-O-Si skeleton chakafanana ne network panguva yekupisa. Simba reSi—O bond (444KJ/mol) rakakwirira kwazvo, kwete chete rakakura kupfuura mamwe polymer bond energy, asiwo rakakura kupfuura ultraviolet energy (399KJ/mol). Maumbirwo emolecular e silicone sealant anoita kuti silicone sealant ive ne high and low tembiricha resistance, emergency resistance uye UV age resistance, pamwe nekushaya mvura yakawanda. Dambudziko resilicone sealant painoshandiswa mu insulating glass ndere high gas permeability.
3. Sarudzo chaiyo yechisimbiso chechipiri chekudzivirira girazi
Kana glue re polysulfide, guruu re polyurethane negirazi zvikaiswa pachiedza chezuva kwenguva yakareba, kubviswa kwegum kunoitika, izvo zvichaita kuti chidimbu chekunze chegirazi rinodzivirira madziro egirazi refuremu yakavanzika chiwire kana kuti kuvharwa kwegirazi rinodzivirira madziro egirazi rine point-supported curtain kukundikane.Saka, chivharo chechipiri chekudzivirira girazi remadziro emaketeni efuremu yakavanzika uye madziro emaketeni efuremu yakavanzika chinofanira kushandisa silicone structural sealant, uye saizi yeinterface inofanira kuverengerwa zvichienderana neJGJ102 "Technical Specifications for Glass Curtain Wall Engineering";
Chivharo chechipiri chekudzivirira girazi remadziro egirazi anotsigira point-supported chinofanira kushandisa silicone structural sealant; kune chechipiri chekudzivirira girazi remadziro emadziro emadziro egirazi akavhurika, zvinokurudzirwa kushandisa silicone structural sealant yekudzivirira girazi.Chivharo chechipiri chegirazi rinodzivirirwa nemagonhi, mahwindo nemadziro akavhurika anogona kunge ari egirazi rinodzivirirwa nemasilicone sealant, polysulfide sealant kana polyurethane sealant.
Zvichibva pane zvataurwa pamusoro apa, vashandisi vanofanira kusarudza chigadzirwa chechipiri chekudzivirira girazi zvichienderana nekushandiswa kwaro kwegirazi rekudzivirira ngura. Pamusana pekuti mhando yechisimbiso inokodzera, chero bedzi yakasarudzwa uye ikashandiswa nemazvo, girazi rekudzivirira ngura rinogona kugadzirwa riine hupenyu hwebasa hunoenderana nezvinodiwa zvekushandiswa. Asi kana rikasasarudzwa zvisizvo uye rikashandiswa zvisizvo, kunyangwe chisimbiso chakanakisa chinogona kugadzira girazi rekudzivirira ngura remhando isina kunaka.
Pakusarudza chivharo chechipiri, kunyanya chivharo chesilicone structural, tinofanirawo kufunga kuti chivharo chesilicone chinofanira kusangana nezvinodiwa zvegirazi rinodziisa, kuenderana nechinhu chikuru chinovhara butyl, uye mashandiro echivharo chesilicone zvinofanira kusangana nezvinodiwa zvezvinodiwa. Panguva imwe chete, kugadzikana kwemhando yezvigadzirwa zvesilicone sealant, kufarirwa kwevagadziri vesilicone sealant, uye kugona kwebasa rehunyanzvi hwemugadziri uye mazinga mukuita kwese kwekutengesa, kutengesa, uye mushure mekutengesa zvinhu zvakakoshawo izvo vashandisi vanofanirwa kufunga nezvazvo.
Chivharo chegirazi chinovhara magirazi chinovhara magirazi chinoderedza mutengo wekugadzirwa kwegirazi rinovhara magirazi, asi chine simba guru pamhando uye hupenyu hwebasa regirazi rinovhara magirazi. Chivharo chegirazi chinovhara magirazi chine chekuita zvakananga nematambudziko ekuchengetedza madziro emaketeni. Parizvino, sezvo makwikwi mumusika wezvivharo ari kuwedzera, vamwe vagadziri vezvivharo havazezi kurega kushanda kwezvigadzirwa nehunhu hwavo pavanenge vachideredza mitengo kuitira kuti vawane vatengi nemitengo yakaderera. Huwandu hwakawanda hwezvigadzirwa zvegirazi zvinovhara magirazi zvinovhara magirazi zvemhando yepasi uye zvemutengo wakaderera zvakaonekwa pamusika. Kana mushandisi akazvisarudza zvisina hanya, kuti achengetedze mari shoma yechivharo, zvinogona kukonzera njodzi dzekuchengetedza kana kutokonzera tsaona dzemhando yepamusoro, izvo zvinogona kukonzera kurasikirwa kukuru.
Siway inokukurudzirai kuti musarudze chigadzirwa chakakodzera uye chigadzirwa chakanaka; panguva imwe chete, tichakuzivisai njodzi dzakasiyana-siyana dzinokonzerwa nekushandisa chivharo chegirazi chemhando yepamusoro chekudzivirira kupisa uye kushandiswa zvisina kunaka mune ramangwana.
