1. Isishwankathelo seglasi yokukhusela
Iglasi efakwe i-insulation luhlobo lweglasi egcina amandla esetyenziswa kakhulu kwizakhiwo zeeofisi zorhwebo, kwiindawo ezinkulu zokuthenga, kwizakhiwo zokuhlala eziphakamileyo nakwezinye izakhiwo. Ineempawu ezibalaseleyo zokuthintela ubushushu kunye nesandi kwaye intle kwaye iyasebenza. Iglasi efakwe i-insulation yenziwe ngeziqwenga ezimbini zeglasi ezidityaniswe nezikhewu. Kukho iintlobo ezimbini eziphambili zokuvala: indlela ye-strip kunye nendlela yokubopha iglu. Okwangoku, i-double seal kwindlela yokubopha iglu yeyona ndlela isetyenziswa kakhulu yokuvala. Isakhiwo sinjengoko siboniswe kuMfanekiso 1: iziqwenga ezimbini zeglasi zahlulwe zi-spacers, kwaye i-butyl sealant isetyenziselwa ukuvala i-spacer kunye neglasi ngaphambili.Gcwalisa ingaphakathi le-spacer ngesihluzo se-molecular, kwaye uvale isithuba esiphakathi komphetho weglasi kunye nomphandle we-spacer nge-sealant yesibini.
Umsebenzi wesitywini sokuqala kukuthintela umphunga wamanzi okanye igesi engasebenziyo ukuba ingene kwaye iphume kwindawo engaphakathi. Isitywini se-butyl sisetyenziswa ngokubanzi kuba izinga lokudluliselwa komphunga wamanzi kunye nezinga lokudluliselwa kwegesi engasebenziyo ye-butyl sealant ziphantsi kakhulu. Nangona kunjalo, isitywini se-butyl ngokwaso sinamandla aphantsi okubopha kunye nokuqina okuphantsi, ngoko ke isakhiwo siphela kufuneka silungiswe ngesitywini sesibini ukuze sidibanise iipleyiti zeglasi kunye nee-spacers. Xa iglasi yokukhusela ingaphantsi komthwalo, umaleko wesitywini unokugcina isiphumo esihle sokutywina. Kwangaxeshanye, isakhiwo siphela asichaphazeleki.

2. Iindidi zezixhobo zokuvala iglasi ezisetyenziswa njenge-sealant yesibini
Kukho iintlobo ezintathu eziphambili ze-sealants zesibini zokukhusela iglasi: i-polysulfide, i-polyurethane kunye ne-silicone. Itheyibhile 1 idwelisa ezinye zeempawu zeentlobo ezintathu ze-sealants emva kokuba zinyangiwe ngokupheleleyo.
Itheyibhile 1 Uthelekiso lweempawu zokusebenza kweentlobo ezintathu ze-sealants zesibini zeglasi yokukhusela
Inzuzo ye-polysulfide sealant kukuba ine-water vapor ephantsi kunye ne-argon gas transmittance kubushushu begumbi; ingxaki yayo kukuba ine-high fluid absorbability rate.
Izinga lokubuyisa i-modulus kunye ne-elastic liyancipha kakhulu njengoko ubushushu busanda, kwaye ukuhanjiswa komphunga wamanzi nako kukhulu kakhulu xa ubushushu buphezulu. Ukongeza, ngenxa yokumelana kwayo nokuguga kwe-UV, ukukhanyiswa kwe-UV ixesha elide kuya kubangela ukususwa kwe-gum okunganamatheliyo.
Inzuzo ye-polyurethane sealant kukuba umphunga wayo wamanzi kunye nokuhanjiswa kwegesi ye-argon kuphantsi, kwaye ukuhanjiswa komphunga wamanzi nako kuphantsi xa ubushushu buphezulu; ingxaki yayo kukuba ayinayo i-UV yokwaluphala.
I-silicone sealant ibhekisa kwi-sealant ene-polysiloxane njengezinto eziphambili zokwenza imveliso, ekwabizwa ngokuba yi-silicone sealant yenkqubo yemveliso yezolimo. I-polymer chain ye-silicone sealant yenziwe kakhulu yi-Si-O-Si, edityaniswe ukuze yenze isakhiwo se-skeleton se-Si-O-Si esifana nenethiwekhi ngexesha lenkqubo yokunyanga. Amandla e-Si—O bond (444KJ/mol) aphezulu kakhulu, kungekuphela nje amakhulu kunamanye amandla e-polymer bond, kodwa akwakhulu kunamandla e-ultraviolet (399KJ/mol). Ulwakhiwo lwe-molecular ye-silicone sealant lwenza i-silicone sealant ibe nokumelana okuhle kakhulu nobushushu obuphezulu nobuphantsi, ukumelana nemozulu kunye nokumelana nokuguga kwe-UV, kunye nokufunxwa kwamanzi okuphantsi. Ingxaki ye-silicone sealant xa isetyenziswa kwiglasi yokukhusela kukungakwazi ukukhupha igesi eninzi.
3. Ukukhetha ngokuchanekileyo isitywina sesibini sokukhusela iglasi
Ukuba umphezulu wokubopha weglue ye-polysulfide, iglue ye-polyurethane kunye neglasi uvezwe elangeni ixesha elide, kuya kwenzeka i-degumming, eya kubangela ukuba iqhekeza langaphandle leglasi yokukhusela yodonga lwekhethini leglasi olufihliweyo liwe okanye ukutywinwa kweglasi yokukhusela yodonga lwekhethini leglasi oluxhaswe yinqaku kungaphumeleli.Ke ngoko, isitywini sesibini sokukhusela iglasi yeendonga zekhethini ezifihliweyo kunye neendonga zekhethini ezifihliweyo kufuneka zisebenzise isitywini sesakhiwo sesilicone, kwaye ubungakanani bomdibaniso kufuneka bubalwe ngokwe-JGJ102 "Iinkcukacha zoBugcisa boBunjineli beKharityhulam yeGlasi";
Isitywini sesibini sokukhusela iglasi yeendonga zekhethini zeglasi ezixhaswa yinqaku kufuneka sisebenzise isitywini sesakhiwo sesilicone; kwisitywini sesibini seglasi yokukhusela kwiindonga zekhethini ezivulekileyo ezinkulu, kucetyiswa ukuba kusetyenziswe isitywini sesakhiwo sesilicone seglasi yokukhusela.Isitywini sesibini seglasi egqunyiweyo yeengcango, iifestile kunye neendonga zekhethini eziqhelekileyo ezivulekileyo zingaba sisitywini se-silicone seglasi egqunyiweyo, isitywini se-polysulfide okanye isitywini se-polyurethane.
Ngokusekelwe koku kungasentla, abasebenzisi kufuneka bakhethe imveliso yesibini efanelekileyo yokutywina iglasi yokukhusela ngokwendlela ethile esetyenziswa ngayo iglasi yokukhusela. Ngenxa yokuba umgangatho wokutywina uyafaneleka, lo gama nje ukhethwe kwaye usetyenziswa ngokufanelekileyo, iglasi yokukhusela inokuveliswa ngobomi benkonzo obuhlangabezana neemfuno zokusetyenziswa. Kodwa ukuba ikhethwe kwaye isetyenziswe ngendlela engafanelekanga, kwaneyona sealant ilungileyo inokuvelisa iglasi yokukhusela ekumgangatho ophantsi.
Xa sikhetha i-sealant yesibini, ingakumbi i-silicone structural sealant, kufuneka siqwalasele nokuba i-silicone sealant kufuneka ihlangabezane neemfuno zokusebenza kweglasi yokukhusela, ukuhambelana ne-primary sealing butyl sealant, kunye nokusebenza kwe-silicone sealant kufuneka kuhlangabezane neemfuno zemigangatho efanelekileyo. Kwangaxeshanye, uzinzo lomgangatho weemveliso ze-silicone sealant, ukuthandwa kwabavelisi be-silicone sealant, kunye nezakhono zobugcisa zomenzi kunye namanqanaba kuyo yonke inkqubo yokuthengisa kwangaphambili, ukuthengisa, kunye nokuthengisa emva kwentengiso nazo zizinto ezibalulekileyo ekufuneka abasebenzisi baziqwalasele.
I-insulant glass sealant ixabisa inxalenye ephantsi yexabiso lonke lokwenziwa kweglasi yokukhusela, kodwa inempembelelo enkulu kumgangatho kunye nobomi benkonzo yeglasi yokukhusela. I-insulant structure sealant yeglasi yokukhusela inxulumene ngokuthe ngqo nemiba yokhuseleko eludongeni lwekhethini. Okwangoku, njengoko ukhuphiswano kwimarike ye-sealant lusiba nzima ngakumbi, abanye abavelisi be-sealant abathandabuzi ukuncama ukusebenza kwemveliso kunye nomgangatho xa benciphisa iindleko ukuze bafumane abathengi ngamaxabiso aphantsi. Inani elikhulu leemveliso ze-insulant glass sealant ezikumgangatho ophantsi nezixabiso liphantsi ziye zavela kwimarike. Ukuba umsebenzisi uyikhetha ngokungakhathali, ukuze onge ixabiso elincinci le-sealant, inokubangela iingozi zokhuseleko okanye ikhokelele kwiingozi zomgangatho, ezinokubangela ilahleko enkulu.
USway ngoku uyakubongoza ukuba ukhethe imveliso elungileyo kunye nemveliso elungileyo; kwangaxeshanye, siza kukwazisa ngeengozi ezahlukeneyo ezibangelwa kukusebenzisa isitywina seglasi esingaphantsi komgangatho kunye nokusetyenziswa okungafanelekanga kwixesha elizayo.
