1. Isishwankathelo seglasi yokugquma
Iglasi ye-insulated luhlobo lweglasi egcina amandla esetyenziswe ngokubanzi kwizakhiwo zeeofisi zorhwebo, iindawo zokuthenga ezinkulu, izakhiwo eziphakamileyo zokuhlala kunye nezinye izakhiwo.Inobushushu obugqwesileyo kunye neempawu zokugquma isandi kwaye intle kwaye iyasebenza.Iglasi egqunyiweyo yenziwe ngamaqhekeza amabini (okanye ngaphezulu) eglasi edityaniswe nezi spacers.Kukho iintlobo ezimbini eziphambili zokutywinwa: indlela yomgca kunye nendlela yokudibanisa iglue.Okwangoku, ukutywinwa kabini kwindlela yokudibanisa iglue yinto esetyenziswa ngokuqhelekileyo ukutywinwa.Ulwakhiwo njengoko kuboniswe kuMfanekiso 1: iziqwenga ezimbini zeglasi zihlukaniswe ngama-spacers, kwaye i-butyl sealant isetyenziselwa ukutywina i-spacer kunye neglasi ngaphambili.Gcwalisa ingaphakathi le-spacer nge-sieve ye-molecular, kwaye uvale i-gap eyenziwe phakathi komphetho weglasi kunye nomphandle we-spacer kunye ne-sealant sealant.
Umsebenzi we-sealant yokuqala kukuthintela umphunga wamanzi okanye igesi ye-inert ukuba ingene kwaye iphume kwi-cavity.I-butyl sealant isetyenziswa ngokubanzi kuba isantya sothumelo lomphunga wamanzi kunye nesantya sothumelo lwerhasi engasebenziyo ye-butyl sealant iphantsi kakhulu.Nangona kunjalo, i-butyl sealant ngokwayo inamandla okubopha okuphantsi kunye nokunwebeka okuphantsi, ngoko ke ulwakhiwo lulonke kufuneka lulungiswe kunye nesitywina sesibini ukudibanisa iipleyiti zeglasi kunye ne-spacers kunye.Xa iglasi ye-insulating iphantsi komthwalo, umaleko we-sealant unokugcina umphumo wokutywinwa kakuhle.Ngexesha elifanayo, isakhiwo esipheleleyo asichaphazeleki.
Umfanekiso woku-1
2. Iindidi ze-sealants zesibini zeglasi ye-insulating
Kukho iintlobo ezintathu eziphambili ze-sealants ze-sealant ze-insulating glass: i-polysulfide, i-polyurethane kunye ne-silicone.Uluhlu loku-1 ludwelisa ezinye iimpawu zeentlobo ezintathu zezitywini emva kokuba ziphilisiwe ngokupheleleyo.
Itheyibhile 1 Ukuthelekiswa kweempawu zokusebenza kweentlobo ezintathu ze-sealants zesibini zeglasi ye-insulating
Inzuzo ye-polysulfide sealant kukuba inomoya ophantsi wamanzi kunye ne-argon gas transmittance kwiqondo lokushisa;isithintelo sayo kukuba inezinga eliphezulu lokufunxa amanzi.
Imodulus kunye ne-elastic recovery rate yehla kakhulu njengoko iqondo lobushushu lisanda, kwaye ukuhanjiswa komphunga wamanzi kukwakhulu kakhulu xa ubushushu buphezulu.Ukongeza, ngenxa yokunganyangeki kokuguga kwe-UV, i-ray ye-UV yexesha elide iya kubangela i-non-stick degumming.
Inzuzo ye-polyurethane sealant kukuba umphunga wayo wamanzi kunye ne-argon gas transmittance iphantsi, kwaye ukuhanjiswa komphunga wamanzi kuphantsi kakhulu xa ubushushu buphezulu;isithintelo sayo kukuba inokumelana nokuguga kwe-UV.
I-Silicone sealant ibhekisa kwi-sealant ene-polysiloxane njengeyona nto iphambili ekrwada, ekwabizwa ngokuba yinkqubo yemveliso yezolimo ye-silicone sealant.Ikhonkco ye-polymer ye-silicone sealant ikakhulukazi iqulunqwe yi-Si-O-Si, edibeneyo edibeneyo ukwenza i-network efana ne-Si-O-Si skeleton structure ngexesha lenkqubo yokunyanga.I-Si-O yamandla ebhondi (444KJ / mol) iphezulu kakhulu, kungekhona nje inkulu kunamanye amandla e-polymer bond, kodwa inkulu kune-ultraviolet amandla (399KJ / mol).Ubume bemolekyuli ye-silicone sealant yenza ukuba i-silicone sealant ibe nokumelana nobushushu obuphezulu kunye nomgangatho ophantsi, ukumelana nemozulu kunye nokumelana nokuguga kwe-UV, kunye nokufunxa amanzi aphantsi.Ukungalungi kwe-silicone sealant xa isetyenziswe kwiglasi yokukhusela i-gas ephezulu.
3. Ukhetho oluchanekileyo lwe-sealant yesibini yeglasi yokugquma
Ukuba indawo edibeneyo yeglue ye-polysulfide, iglue ye-polyurethane kunye neglasi ibonakaliswe ekukhanyeni kwelanga ixesha elide, i-degumming iya kwenzeka, eya kubangela ukuba iqhekeza langaphandle leglasi ekhuselayo yodonga olufihliweyo lweglasi liwe okanye ukutywinwa kweglasi. insulating glass of point-supported glass curtain wall ukusilela.Ngoko ke, i-sealant yesibini yokugquma iglasi yeendonga zesakhelo ezifihlakeleyo zesakhelo somkhusane kunye neendonga zesakhelo ezifihlakeleyo zesakhelo kufuneka zisebenzise i-silicone yesakhiwo sealant, kwaye ubungakanani bojongano kufuneka lubalwe ngokutsho kwe-JGJ102 "IiNkcazo zobuGcisa zeGlass Curtain Wall Engineering";
Isitywina sesibini sokukhusela iglasi yeendonga zeglasi ezixhasayo kufuneka zisebenzise i-silicone structural sealant;kwisitywina sesibini seglasi yokugquma iindonga ezinkulu ezivulekileyo zamakhethini, kuyacetyiswa ukuba kusetyenziswe isigqubuthelo seglasi ye-silicone yesakhiwo sealant.Isitywina sesibini seglasi egqunyiweyo kwiingcango, iifestile kunye neendonga ezivulekileyo zekhethini ezivulekileyo zinokufakwa iglasi ye-silicone sealant, i-polysulfide sealant okanye i-polyurethane sealant.
Ngokusekwe koku ngasentla, abasebenzisi kufuneka bakhethe imveliso efanelekileyo yesitywina yesibini yeglasi yokugquma ngokwenkqubo ethile yeglasi yokugquma.Kwisiseko sokuba umgangatho we-sealant ufanelekile, ngokude nje ukhethwe kwaye usetyenziswe ngokufanelekileyo, i-glass insulating inokuveliswa kunye nobomi benkonzo obuhlangabezana neemfuno zokusetyenziswa.Kodwa ukuba ayikhethwanga ngokufanelekileyo kwaye isetyenziswe ngokungafanelekanga, kwanesona sitywino silungileyo sinokuvelisa iglasi yokugquma ekumgangatho ophantsi.
Xa ukhetha isitywina sesibini, ngakumbi i-silicone sealant yesakhiwo, kufuneka kwakhona sithathele ingqalelo ukuba i-silicone sealant kufuneka ihlangabezane neemfuno zokusebenza zeglasi yokugquma, ukuhambelana nokutywinwa okuphambili kwe-butyl sealant, kunye nokusebenza kwe-silicone sealant kufuneka ihlangabezane neemfuno. yemigangatho efanelekileyo.Kwangaxeshanye, ukuzinza komgangatho weemveliso ze-silicone sealant, ukuthandwa kwabavelisi be-silicone sealant, kunye nobuchule benkonzo yobugcisa bomenzi kunye namanqanaba kuyo yonke inkqubo yokuthengisa kwangaphambili, ukuthengisa, kunye nokuthengiswa emva kokuthengisa nazo zizinto ezibalulekileyo ezifunwa ngabasebenzisi. ukucingela.
I-insulating glass sealant yenza umlinganiselo ophantsi weendleko zokwenziwa kweglasi yokugquma, kodwa inempembelelo enkulu kumgangatho kunye nobomi benkonzo yeglasi yokugquma.I-insulating glass structural sealant ihambelana ngqo nemiba yokhuseleko lwamakhethini.Okwangoku, njengoko ukhuphiswano kwiimarike ze-sealant luba lubi kakhulu, abanye abavelisi be-sealant abanqikazi ukuncama ukusebenza kwemveliso kunye nomgangatho xa benciphisa iindleko ukuze baphumelele abathengi ngamaxabiso aphantsi.Inani elibonakalayo lemveliso ekumgangatho ophantsi kunye nexabiso eliphantsi lokugquma isigqubuthelo seglasi livele kwintengiso.Ukuba umsebenzisi ukhetha ngokungakhathali, ukwenzela ukugcina ixabiso elincinci le-sealant, kunokubangela iingozi zokhuseleko okanye kukhokelela kwiingozi ezisemgangathweni, ezinokubangela ilahleko enkulu.
U-Siway uyakubongoza ukuba ukhethe imveliso eyiyo kunye nemveliso elungileyo;kwangaxeshanye, siya kukwazisa ngeengozi ezahlukeneyo ezibangelwa kukusetyenziswa komgangatho ophantsi wokugquma iglasi yesitywina sesibini kunye nokusetyenziswa ngokungafanelekanga kwixesha elizayo.
