Ukusetshenziswa kwe-insulating glass sealant (1): Ukukhetha okulungile kwe-sealant yesibili

1. Uhlolojikelele lwengilazi ye-insulating

.

Ingilazi evalekile iwuhlobo lwengilazi yokonga amandla esetshenziswe kabanzi ezakhiweni zamahhovisi ezentengiselwano, izitolo ezinkulu, izakhiwo eziphakeme zokuhlala nezinye izakhiwo.Ine-insulation yokushisa enhle kakhulu kanye nezakhiwo zokuvala umsindo futhi yinhle futhi iyasebenza.Ingilazi evalekile yenziwe ngezingcezu ezimbili (noma ngaphezulu) zengilazi eziboshwe ngama-spacers.Kunezinhlobo ezimbili eziyinhloko zokubeka uphawu: indlela yomugqa kanye nendlela yokuhlanganisa iglue.Njengamanje, uphawu oluphindwe kabili endleleni yokubopha iglue yisakhiwo sokuvala esisetshenziswa kakhulu.Isakhiwo sinjengoba kukhonjisiwe kuMfanekiso 1: izingcezu ezimbili zengilazi zihlukaniswa ngama-spacers, futhi i-butyl sealant isetshenziselwa ukuvala i-spacer nengilazi ngaphambili.Gcwalisa ingaphakathi le-spacer ngesisefo samangqamuzana, bese uvala igebe elakhiwe phakathi konqenqema lwengilazi nangaphandle kwe-spacer ngesealant yesibili.

.

Umsebenzi we-sealant yokuqala ukuvimbela umhwamuko wamanzi noma igesi ye-inert ukuthi ingangeni futhi iphume emgodini.I-butyl sealant ivame ukusetshenziswa ngenxa yokuthi izinga lokudluliswa komhwamuko wamanzi kanye nezinga lokudluliswa kwegesi engasebenzi ye-butyl sealant liphansi kakhulu.Kodwa-ke, i-butyl sealant ngokwayo inamandla okubopha aphansi kanye nokunwebeka okuphansi, ngakho-ke ukwakheka okuphelele kufanele kuhlanganiswe nesealant yesibili ukuze kuhlanganiswe amapuleti engilazi nama-spacers ndawonye.Lapho ingilazi ye-insulating ingaphansi komthwalo, ungqimba lwe-sealant lungagcina umphumela omuhle wokuvala.Ngesikhathi esifanayo, isakhiwo sonke asithinteki.

2. Izinhlobo zama-sealants esibili zokuvala ingilazi

.

Kunezinhlobo ezintathu eziyinhloko zama-sealants wesibili wengilazi yokushisa: i-polysulfide, i-polyurethane ne-silicone.Ithebula 1 libala ezinye izici zezinhlobo ezintathu zama-sealant ngemva kokwelashwa ngokugcwele.

Ukuqhathaniswa kwezici zokusebenza kwezinhlobo ezintathu zama-sealants wesibili wengilazi yokuvikela

Ithebula 1 Ukuqhathaniswa kwezimpawu zokusebenza kwezinhlobo ezintathu zama-sealants wesibili wengilazi yokuvikela

Inzuzo ye-polysulfide sealant yukuthi inomoya ophansi wamanzi kanye ne-argon gas transmittance ekamelweni lokushisa;ububi bayo ukuthi inezinga eliphezulu lokumunca amanzi.

Izinga le-modulus ne-elastic recovery rate liyancipha kakhulu njengoba izinga lokushisa likhuphuka, futhi ukudluliswa komhwamuko kukhulu kakhulu uma izinga lokushisa liphezulu.Ngaphezu kwalokho, ngenxa yokungagugi kahle kwe-UV, imisebe yesikhathi eside ye-UV izobangela ukuchithwa kwe-non-stick.

.

Inzuzo ye-polyurethane sealant ukuthi umhwamuko wayo wamanzi kanye ne-argon gas transmittance iphansi, futhi ukudluliswa komhwamuko wamanzi nakho kuphansi uma izinga lokushisa liphezulu;ububi bayo ukuthi ayinayo ukumelana nokuguga kwe-UV.

.

I-Silicone sealant ibhekisela ku-sealant ene-polysiloxane njengento eluhlaza eyinhloko, ebizwa nangokuthi uhlelo lokukhiqiza lwezolimo lwe-silicone sealant.Iketango le-polymer le-silicone sealant lakhiwa ikakhulukazi i-Si-O-Si, exhunywe ngokuphambana ukwenza uhlaka lwamathambo enethiwekhi olufana ne-Si-O-Si ngesikhathi senqubo yokwelapha.Amandla ebhondi ye-Si—O (444KJ/mol) aphakeme kakhulu, hhayi nje kuphela amakhulu kakhulu kunamanye amandla ebhondi ye-polymer, kodwa futhi makhulu kunamandla e-ultraviolet (399KJ/mol).Isakhiwo samangqamuzana e-silicone sealant senza i-silicone sealant ibe nokumelana nokushisa okuphezulu kakhulu nokuphansi, ukumelana nesimo sezulu kanye nokumelana nokuguga kwe-UV, kanye nokumuncwa kwamanzi aphansi.Ububi be-silicone sealant uma isetshenziswa ku-insulating glass ukukwazi ukungena kwegesi ephezulu.

3. Ukukhethwa okulungile kwe-sealant yesibili yengilazi yokushisa

.

Uma i-bonding surface ye-polysulfide glue, i-polyurethane glue kanye nengilazi ivezwa elangeni isikhathi eside, i-degumming izokwenzeka, okuzokwenza ukuthi ucezu lwangaphandle lwengilazi evikelayo yodonga lwamakhethini lwengilazi olufihliwe luwe noma ukubekwa uphawu ingilazi evikelayo yodonga lwekhethini yengilazi esekelwe iphuzu ukuze ihluleke.Ngakho-ke, isivalo sesibili sokuvikela ingilazi yezindonga zekhethini zohlaka olufihliwe kanye nezindonga zekhethini zohlaka olufihleke kancane kufanele zisebenzise i-silicone structural sealant, futhi usayizi wesixhumi esibonakalayo kufanele abalwe ngokuya nge-JGJ102 "Izicaciso Zobuchwepheshe Zobunjiniyela Bodonga Lwengilazi Yekhethini";

I-sealant yesibili yokuvikela ingilazi yezindonga zamakhethini engilazi esekelwe iphuzu kumele isebenzise i-silicone structural sealant;Ukuze uthole uphawu lwesibili lwengilazi evikelayo yezindonga zamakhethini ezinosayizi omkhulu ovulekile, kunconywa ukusebenzisa ingilazi yokuvikela i-silicone structural sealant.I-sealant yesibili yengilazi evalekile yezicabha, amafasitela kanye nezindonga zamakhethini ezivulekile ezijwayelekile zingafakwa ingilazi ye-silicone sealant, i-polysulfide sealant noma i-polyurethane sealant.

Ngokusekelwe kulokhu okungenhla, abasebenzisi kufanele bakhethe umkhiqizo ofanelekile we-sealant wesibili wengilazi ye-insulating ngokuya ngokusetshenziswa okukhethekile kwengilazi yokuvikela.Ngokwesisekelo sokuthi ikhwalithi ye-sealant ifanelekile, inqobo nje uma ikhethiwe futhi isetshenziswa kahle, ingilazi yokuvikela ingakhiqizwa ngempilo yesevisi ehlangabezana nezidingo zokusetshenziswa.Kodwa uma kukhethwe ngokungafanele futhi kusetshenziswe, ngisho ne-sealant engcono kakhulu ingase ikhiqize ingilazi evikelayo yekhwalithi ephansi.

Uma sikhetha isivalo sesibili, ikakhulukazi i-silicone structural sealant, kufanele futhi sicabangele ukuthi isivalo se-silicone kufanele sihlangabezane nezimfuneko zokusebenza zengilazi evikelayo, ukuhambisana ne-primary sealant butylant, kanye nokusebenza kwe-silicone sealant kufanele kuhlangabezane nezidingo. wamazinga afanele.Ngasikhathi sinye, ukuzinza kwekhwalithi yemikhiqizo ye-silicone sealant, ukuthandwa kwabakhiqizi be-silicone sealant, kanye namakhono wesevisi yomkhiqizi kanye namazinga kuyo yonke inqubo yokuthengisa kwangaphambili, ukuthengisa, kanye nokuthengiswa kwangemva kokuthengisa nakho kuyizinto ezibalulekile ezidingwa abasebenzisi. ukucabangela.

.

I-insulating glass sealant ibala ingxenye ephansi yazo zonke izindleko zokukhiqiza ingilazi evikelayo, kodwa inomthelela omkhulu kwikhwalithi kanye nempilo yesevisi yengilazi yokushisa.I-insulating glass structural sealant ihlobene ngokuqondile nezindaba zokuphepha kodonga lwamakhethini.Njengamanje, njengoba ukuncintisana emakethe ye-sealant kuya ngokuya kushuba, abanye abakhiqizi be-sealant abanqikazi ukudela ukusebenza komkhiqizo kanye nekhwalithi lapho behlisa izindleko ukuze bawine amakhasimende ngamanani aphansi.Inani elikhulu lemikhiqizo yokuvikela ingilazi evala ingilazi esezingeni eliphansi futhi enenani eliphansi ivele emakethe.Uma umsebenzisi ekhetha ngokunganaki, ukuze asindise izindleko ezincane ze-sealant, kungabangela izingozi zokuphepha noma kuholele ngisho nezingozi zekhwalithi, ezingabangela ukulahlekelwa okukhulu.

.

U-Siway ngalokhu ukunxusa ukuba ukhethe umkhiqizo olungile nomkhiqizo omuhle;ngesikhathi esifanayo, sizokwethula kuwe izingozi ezihlukahlukene ezibangelwa ukusebenzisa ingilazi yezinga eliphansi le-insulating sealant yesibili kanye nokusetshenziswa okungalungile esikhathini esizayo.
