Eminyakeni yamuva nje, kube nesimo sezulu esibi kakhulu emhlabeni jikelele, esiphinde sahlola imboni yethu ye-sealant, ikakhulukazi ezimbonini zaseShayina ezifana nathi ezithumela kuzo zonke izingxenye zomhlaba.
Emasontweni ambalwa adlule e-China, imvula eqhubekayo kanye namazinga okushisa aphezulu akushiyi indawo yokuphumula. Ngakho-ke ungafaka kanjani ama-sealants ngendlela efanele endaweni yokushisa ephezulu kanye nemvelo enomswakama ophezulu?
1 Ukupakishwa nokugcinwa kwama-sealant
Njengoba ama-sealant eyimikhiqizo yamakhemikhali, indlela yokwelapha iwukusabela futhi iqine lapho ihlangana nomswakama. Uma kucwiliswe emanzini, ukupakishwa kwangaphandle kwama-sealants kungadlala indima yokuvimbela okulinganiselwe. Ngakho-ke, ehlobo, ama-sealants kufanele agcinwe endaweni ephakeme kakhulu, enomoya futhi epholile ukuvimbela ama-sealants ukuthi angacwiliswa yimvula noma ngisho nokucwiliswa emanzini okubangelwa isimo sezulu esibi kakhulu, okuzophazamisa impilo yeshalofu yomkhiqizo kanye nembangela. ukwelapha izinkinga emaphaketheni omkhiqizo.
Ama-sealants afakwe emanzini kufanele asuswe endaweni yokucwiliswa ngokushesha ngangokunokwenzeka futhi adluliselwe ekamelweni elomile nelingena umoya. Ibhokisi lokupakisha langaphandle kufanele lisuswe, indawo engaphezulu kufanele isulwe yome futhi ifakwe endlini ukuze isetshenziswe ngokushesha ngangokunokwenzeka.
2 Indlela elungile yokufaka i-sealant
Ngaphambi kokufaka isicelo, sicela unake okulandelayo:
Imfuneko yezinga lokushisa elizungezile yomkhiqizo we-Siwayi-silicone sealantimikhiqizo yilena: 4℃～40℃, indawo ehlanzekile enomswakama ohlobene ongu-40%～80%.
Ezindaweni ezingaphandle kwezimfuneko ezingenhla zezinga lokushisa nokuswakama, abasebenzisi abanconywa ukuthi bafake isivalo.
Ehlobo, izinga lokushisa langaphandle liphezulu, ikakhulukazi izindonga zamakhethini e-aluminium, lapho izinga lokushisa liphakeme nakakhulu. Uma izinga lokushisa elizungezile nomswakama ungekho phakathi kwebanga elinconyiwe, kunconywa ukwenza indawo encane yokuhlolwa kwesicelo se-sealant esizeni, futhi wenze ukuhlolwa kokunamathela kokucwecwa ukuze kuqinisekiswe ukuthi ukunamathela kuhle futhi azikho izinto ezimbi ngaphambili. ukuyisebenzisa endaweni enkulu.
Ngesikhathi sokufaka isicelo, sicela ulandele lezi zinyathelo ezingezansi:
Ukulandelana kokwakhiwa kwe-structural sealant (i-structural sealant yezindonga zamakhethini, i-sealant yesakhiwo enezingqimba ezimbili, njll.):
1) Hlanza i-substrate
Izinga lokushisa liphezulu ehlobo, futhi i-solvent yokuhlanza kulula ukuguquguquka. Naka umthelela kumphumela wokuhlanza.
2) Faka i-primer (uma kunesidingo)
Ehlobo, izinga lokushisa nomswakama kuphezulu, futhi i-primer ilula ukwenza i-hydrolyze futhi ilahlekelwe umsebenzi wayo emoyeni. Naka ukujova iglue ngokushesha ngangokunokwenzeka ngemva kokufaka i-primer. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inani lezikhathi kanye nesikhathi lapho i-primer ixhumana khona nomoya kufanele kuncishiswe ngangokunokwenzeka. Kungcono ukusebenzisa ibhodlela elincane lokubuyisela ukupakisha.
3) Umjovo we-sealant
Ngemuva komjovo weglue, i-sealant ephikisana nesimo sezulu ayikwazi ukusetshenziswa ngokushesha ngaphandle, ngaphandle kwalokho, isivinini sokuphulukisa se-sealant yesakhiwo sizoncishiswa kakhulu.
4) Ukunquma
Ngemuva kokuthi umjovo weglue usuqediwe, ukusika kufanele kwenziwe ngokushesha, okulungele ukuxhumana phakathi kwe-sealant kanye nohlangothi lwesixhumi esibonakalayo.
5) Ukurekhoda nokumaka
Ngemva kokuba inqubo engenhla isiqediwe, rekhoda futhi umake ngesikhathi.
6) Isondlo
Iyunithi kufanele yelashwe isikhathi esanele ngaphansi kwezimo ezimile nezingacindezelwe ukuze kuqinisekiswe ukuthi i-sealant yesakhiwo inokunamathela okwanele.
Ukulandelana kokwakhiwa kwe-sealant emelana nesimo sezulu kanye nesivalo nesivalo sewindi:
1) Ukulungiswa okuhlangene kwe-sealant
Induku yegwebu exhumene ne-sealant kufanele igcinwe injalo. Izinga lokushisa liphezulu ehlobo, futhi uma induku ye-foam yonakalisiwe, kulula ukubangela ukuqhuma; ngesikhathi esifanayo, kufanele kuqashelwe ukuhambisana kwe-substrate kanye ne-sealant.
2） Hlanza i-substrate
Ukuhlanganiswa kweglue kufanele kuhlanzwe endaweni ukuze kukhishwe uthuli, amafutha, njll.
3) Faka i-primer (uma kunesidingo)
Okokuqala, qiniseka ukuthi ubuso be-glue joint substrate bomile ngokuphelele. Ehlobo, izinga lokushisa nomswakama kuphezulu, futhi i-primer i-hydrolyzed kalula emoyeni futhi ilahlekelwa umsebenzi wayo. Kumele kuqashelwe ukuthi i-glue kufanele ijovwe ngokushesha ngangokunokwenzeka ngemuva kokusetshenziswa kwe-primer. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inombolo kanye nesikhathi sokuxhumana nomoya kufanele kuncishiswe ngangokunokwenzeka. Kungcono ukusebenzisa ibhodlela elincane lokubuyisela ukupakisha.
4) Umjovo we-sealant
Kukhona ukuduma kwezulu okwengeziwe ehlobo. Qaphela ukuthi ngemva kwemvula, inhlanganisela yeglue kumele yome ngokuphelele ngaphambi kokujova i-glue.
5) Ukuqeda
Izinga lokushisa ehlobo liphezulu, futhi isikhathi sokuqeda sifushane kunezinye izinkathi zonyaka. Ngemuva kokuthi umjovo weglue usuqediwe, ukuqedwa kufanele kwenziwe ngokushesha.
6) Isondlo
Esigabeni sokuqala sokulungiswa, akufanele kube khona ukufuduka okukhulu.
Izinkinga ezivamile, Indlela yokubhekana nazo:
1. Isikhathi sokuphumula esifushane se-sealant yesakhiwo sezingxenye ezimbili
Ukwahlulela: Isikhathi sekhefu sifushane kunomkhawulo ophansi wesikhathi sekhefu esinconywe umenzi.
Isizathu: Izinga lokushisa eliphezulu kanye nomswakama ehlobo kunciphisa isikhathi sokuphumula.
Isixazululo: Lungisa isilinganiso sezingxenye A no-B ngaphakathi kwebanga elinconywe umenzi.
2. Ukungasebenzi kwe-structural sealant primer
Isizathu: Izinga lokushisa eliphezulu kanye nomswakama ehlobo, ukusetshenziswa okungalungile kwe-primer kungalahlekelwa umsebenzi wayo kalula. I-primer engasebenzi kahle izoholela ekuhlanganisweni okubi kwe-structural sealant.
Isixazululo: Kungcono ukusebenzisa amabhodlela amancane ukwenza i-primer. Akunconywa ukusebenzisa i-primer engasetshenziswanga ebhodleleni elingaphansi ubusuku bonke. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inombolo kanye nesikhathi sokuxhumana phakathi kwe-primer nomoya kufanele kuncishiswe ngangokunokwenzeka. Futhi hlola isimo se-primer ebhodleleni elincane ngesikhathi. Uma ukubukeka kushintshile ngenxa yesikhathi eside sokugcina, i-primer ebhodleleni elincane akufanele isetshenziswe.
3. I-Weathering sealant/umnyango kanye nokubhayiza kwe-sealant yefasitela
Indlela yokwahlulela: Kunamaqhuqhuva endawo ebusweni be-silicone sealant. Lapho umucu ophulukisiwe usikwa uvuleke, ingaphakathi lingenalutho.
Isizathu ①: Ingaphezulu lenduku yegwebu libhobozwa phakathi nenqubo yokugcwalisa, futhi umoya uphuma embobeni ngemva kokukhanywa;
Isixazululo: Uhlangothi lwenduku yegwebu oluxhumene nesivalo luhlala lunjalo. Uma kunzima ukugcwalisa, ungakwazi ukusika ingxenye ngemuva kwenduku ye-foam.
Isizathu ②: Amanye ama-substrates asabela ngezinsimbi;
Isixazululo: Naka ukuhambisana kwezinhlobo ezahlukene zama-sealant nama-substrates, futhi nokuhlolwa kokuhambisana kuyadingeka.
Isizathu ③: Ukugwedla okubangelwa ukwanda okushisayo kwegesi endaweni ehlanganisiwe yeglue;
Isizathu esiqondile singase sibe ukuthi kulo lonke ilunga leglue elivaliwe, umoya ovalwe esigxotsheni seglue ngemva komjovo uyanda ngevolumu lapho izinga lokushisa liphezulu (ngokuvamile lingaphezu kuka-15°C), okubangela ukubhuquza phezu kwesivalo esingakafiki. kuqinisiwe.
Isixazululo: Gwema ukuvala uphawu ngokuphelele ngangokunokwenzeka. Uma kunesidingo, shiya ingxenye encane yemigodi yokukhipha umoya bese uyigcwalisa ngemva kokuba i-sealant iqina.
Isizathu ④: Isixhumi esibonakalayo noma into eyisisetshenziswa imanzi;
Isixazululo: Ungakhi ngezinsuku zemvula, linda kuze kube yilapho isimo sezulu sicacile futhi inhlanganisela yeglue yomile.
Isizathu ⑤: Ukwakhiwa ngaphansi kwezimo zokushisa eziphakeme ngaphandle;
Isixazululo: Misa ukwakhiwa ngaphansi kwezimo zokushisa eziphezulu ngaphandle bese ulinda kuze kube yilapho izinga lokushisa lehla ngaphambi kokwakhiwa.
4. Isikhathi esifushane sokulungisa i-sealant engamelana nesimo sezulu/umnyango kanye ne-window sealant
Isizathu: Izinga lokushisa kanye nomswakama kuphezulu ehlobo, futhi isikhathi sokudonsa sifinyezwa.
Isixazululo: Lungisa ngesikhathi ngemuva komjovo.
Qaphela ngesikhathi sokwakhiwa futhi ulandele imiyalelo ukuze uqinisekise ikhwalithi.
Ukushisa okuphezulu kanye nemvula enkulu kuyizinselele ezinkulu, futhi kukhona amaqhinga okwakhiwa kwe-sealant.
Bhekana nezinkinga ngesikhathi ukuze uqinisekise ukuphepha kwephrojekthi.
I-SIWAY ikuphelezela ehlobo elishisayo futhi inika ubuhle ndawonye!
