1. Mhedziso yegirazi inodzivirira
.
Girazi insulated imhando yegirazi rinochengetedza simba rakashandiswa zvakanyanya muzvivako zvehofisi zvebhizimisi, nzvimbo huru dzekutengesa, zvivako zvepamusoro zvekugara uye zvimwe zvivako.Iyo ine yakanakisa kupisa kupisa uye inonzwika insulation zvimiro uye yakanaka uye inoshanda.Girazi rinodzivirirwa rinoumbwa nezvidimbu zviviri (kana kupfuura) zvegirazi zvakabatanidzwa ne spacers.Kune maviri makuru emhando yekuisa chisimbiso: iyo strip nzira uye glue bonding nzira.Parizvino, chisimbiso chechipiri mu glue bonding nzira ndiyo inonyanya kushandiswa yekuisa chisimbiso.Chimiro chacho sezvakaratidzwa mumufananidzo 1: zvidimbu zviviri zvegirazi zvakaparadzaniswa nespacers, uye butyl sealant inoshandiswa kuvhara spacer uye girazi kumberi.Zadza mukati me spacer ne molecular sieve, uye simbisa gap rakaumbwa pakati pemupendero wegirazi uye kunze kwe spacer ine yechipiri sealant.
.
Basa rekutanga sealant nderokudzivirira mhute yemvura kana inert gasi kubva pakupinda nekubuda mugomba.Butyl sealant inowanzo shandiswa nekuti mwero wekutapurirana kwehuputi hwemvura uye inert gasi rekufambisa rebutyl sealant rakaderera.Nekudaro, butyl sealant pachayo ine yakaderera bonding simba uye yakaderera elasticity, saka chimiro chese chinofanira kugadzikwa nechechipiri chisimbiso kubatanidza mahwendefa egirazi uye spacers pamwechete.Kana iyo insulating girazi iri pasi pemutoro, dhizaini ye sealant inogona kuchengetedza yakanaka yekuisa chisimbiso.Panguva imwecheteyo, chimiro chakazara hachina kukanganiswa.

2. Mhando dzechipiri sealants ye insulating glass
.
Kune matatu makuru emhando dzechipiri sealants ye insulating girazi: polysulfide, polyurethane uye silicone.Tafura 1 inonyora mamwe maitiro emhando nhatu dzezvisimbiso mushure mekunge dzanyatsorapwa.
Tafura 1 Kuenzanisa kwekuita maitiro emhando nhatu dzechipiri sealants ye insulating girazi
Kubatsira kwe polysulfide sealant ndeyekuti ine yakaderera mvura mhute uye argon gasi transmittance pane tembiricha;kuipa kwayo ndeyekuti ine mwero wakanyanya wekutora mvura.
Iyo modulus uye elastic kudzoreredza mwero inodzikira zvakanyanya sezvo tembiricha inowedzera, uye iyo mvura vapor transmittance zvakare yakakura kwazvo kana tembiricha yakakwira.Uye zvakare, nekuda kwekushomeka kwayo kweUV kuchembera kuramba, nguva refu UV irradiation inokonzeresa isiri-tsvimbo degumming.
.
Kubatsira kwe polyurethane sealant ndeyokuti mhute yayo yemvura uye argon gasi transmittance yakaderera, uye iyo vapor transmittance yemvura zvakare yakaderera kana tembiricha yakakwira;chakashata chayo ndechekuti ine murombo UV kuchembera kuramba.
.
Silicone sealant inoreva chisimbiso chine polysiloxane sechinhu chikuru mbishi, chinonziwo zvekurima kugadzirwa system silicone sealant.Iyo polymer cheni yesilicone sealant inonyanya kuumbwa neSi-O-Si, iyo yakabatana-yakabatana kugadzira network-yakaita Si-O-Si skeleton chimiro panguva yekurapa.Simba reSi-O bond (444KJ / mol) rakakwirira kwazvo, kwete chete rakakura kudarika mamwe mapolymer bond simba, asiwo yakakura kudarika ultraviolet simba (399KJ / mol).Iyo molecular chimiro chesilicone sealant inogonesa silicone sealant kuve nepamusoro uye yakaderera tembiricha kuramba, mamiriro ekunze uye UV kuramba kuchembera, pamwe nekudzika kwemvura kunyura.Iko kusakosha kwesilicone sealant kana ichishandiswa mukuvharidzira girazi ndeyepamusoro gasi permeability.
3. Kusarudzwa kwakarurama kwechipiri chisimbiso chegirazi rekudzivirira
.
Kana iyo yekubatanidza pamusoro pe polysulfide glue, polyurethane glue uye girazi zvakafumurwa kuchiedza chezuva kwenguva yakareba, degumming ichaitika, izvo zvinozoita kuti chikamu chekunze chegirazi inodzivirira yegirazi rakavanzika girazi madziro kudonha kana kuiswa chisimbiso. insulating girazi renzvimbo-inotsigirwa girazi keteni madziro kutadza.Naizvozvo, yechipiri chisimbiso kuti insulating girazi yakavanzwa furemu keteni madziro uye semi-yakavanzwa furemu keteni madziro anofanira kushandisa silicone structural sealant, uye interface saizi inofanira kuverengwa maererano JGJ102 "Technical Specifications nokuti Glass Curtain Wall Engineering";
Iyo yechipiri sealant ye insulating girazi yepoint-inotsigirwa girazi keteni madziro inofanira kushandisa silicone structural sealant;kune yechipiri chisimbiso che insulating girazi kune yakakura-yakavhurika furemu madziro emadziro, zvinokurudzirwa kushandisa insulating girazi silicone structural sealant.Chechipiri chisimbiso chegirazi rakavharirwa magonhi, mahwindo uye akajairwa-akavhurika-furemu keteni madziro anogona kuiswa insulated girazi silicone sealant, polysulfide sealant kana polyurethane sealant.
Zvichienderana nezviri pamusoro, vashandisi vanofanirwa kusarudza iyo yakakodzera yechipiri sealant chigadzirwa chekuisa insulating girazi maererano nekushandiswa chaiko kwegirazi rekudzivirira.Pamusana pekuti sealant quality inokodzera, chero bedzi yakasarudzwa uye yakashandiswa zvakanaka, girazi rekudzivirira rinogona kugadzirwa nehupenyu hwebasa hunosangana nezvinodiwa zvekushandisa.Asi kana isina kusarudzwa uye ikashandiswa zvisina kunaka, kunyangwe iyo yakanakisa sealant inogona kuburitsa insulating girazi reunhu husina kunaka.
Pakusarudza yechipiri chisimbiso, kunyanya iyo silicone structural sealant, isu tinofanirawo kufunga kuti silicone sealant inofanirwa kusangana nezvinodiwa zvegirazi inodzivirira, kuenderana neiyo yekutanga chisimbiso butyl sealant, uye kushanda kwesilicone sealant kunofanirwa kuzadzisa zvinodiwa. yezviyero zvinoenderana.Panguva imwecheteyo, kugadzikana kwemhando yezvigadzirwa zvesilicone sealant, kufarirwa kwevagadziri vesilicone sealant, uye kugona kwemugadziri webasa rehunyanzvi uye mazinga mukuita kwese kwekutanga kutengesa, kutengesa, uye mushure mekutengesa zvinhu zvakakosha izvo vashandisi vanoda. kufunga.
.
Insulating girazi sealant inoverengera yakaderera chikamu chese insulating girazi kugadzira mutengo, asi ine simba guru pamhando uye sevhisi yehupenyu hwegirazi inodzivirira.Insulating girazi structural sealant inotoenderana zvakananga necurtain wall security issues.Parizvino, sezvo kukwikwidza mumusika we sealant kunowedzera kutyisa, vamwe vanogadzira sealant havazeze kupira kuita kwechigadzirwa uye kunaka pavanenge vachideredza mitengo kuitira kuhwina vatengi pamitengo yakaderera.Huwandu hwakati wandei hwemhando yakaderera uye yakaderera-yemutengo insulating girazi sealant zvigadzirwa zvakaonekwa pamusika.Kana mushandisi akaisarudza zvisina hanya, kuitira kuchengetedza mari shoma yekuisa chisimbiso, inogona kukonzera njodzi dzekuchengetedza kana kutotungamira njodzi dzemhando, izvo zvinogona kukonzera kurasikirwa kukuru.
.
Siway apa inokukurudzira kuti usarudze chigadzirwa chakanaka uye chakanaka;panguva imwe chete, tichakuzivisai njodzi dzakasiyana-siyana dzinokonzerwa nekushandisa yakaderera-yemhando insulating girazi yechipiri sealant uye kushandiswa kusina kunaka mune ramangwana.
