Eminyakeni yamuva nje, kube nesimo sezulu esibi kakhulu emhlabeni jikelele, okuye kwavivinya nemboni yethu yokuvala imfucuza, ikakhulukazi ezimbonini zaseShayina ezifana nathi ezithumela kwamanye amazwe kuzo zonke izingxenye zomhlaba.
Emasontweni ambalwa edlule eShayina, imvula eqhubekayo kanye namazinga okushisa aphezulu akushiyi ndawo yokuphumula. Ngakho-ke ungazifaka kanjani izithiyo zokuvala endaweni enokushisa okuphezulu kanye nomswakama ophezulu?
1 Ukupakishwa nokugcinwa kwezivalo zokuvala
Njengoba izinto zokuvala zingumkhiqizo wamakhemikhali, indlela yokupholisa iwukusabela nokuqina lapho zihlangana nomswakama. Uma zicwiliswe emanzini, ukupakishwa kwangaphandle kwezinto zokuvala kungadlala indima encane yokuvimbela. Ngakho-ke, ehlobo, izinto zokuvala kufanele zigcinwe endaweni epholile, enomoya futhi epholile ukuvimbela izinto zokuvala ukuthi zingacwiliswa emvuleni noma ngisho zicwiliswe emanzini okubangelwa isimo sezulu esibi kakhulu, okuzothinta isikhathi sokuphila komkhiqizo futhi kubangele izinkinga zokuvala ekupakishweni komkhiqizo.
Ama-sealant acwiliswe emanzini kufanele asuswe endaweni yokucwilisa ngokushesha okukhulu bese edluliselwa ekamelweni elomile nelinomoya. Ibhokisi lokupakisha langaphandle kufanele lisuswe, indawo engaphezulu kufanele isulwe yome bese ifakwa endlini ukuze isetshenziswe ngokushesha okukhulu.
2 Indlela efanele yokufaka isivalo
Ngaphambi kokufaka isicelo, sicela unake okulandelayo:
Isidingo sokushisa okuzungezile somkhiqizo we-Siwayisivalo se-siliconeimikhiqizo ingu: 4℃～40℃, indawo ehlanzekile enomswakama olinganiselwe ongu-40%～80%.
Ezindaweni ezingezona izidingo zokushisa nomswakama ezingenhla, abasebenzisi abanconywa ukufaka i-sealant.
Ehlobo, izinga lokushisa langaphandle liphezulu, ikakhulukazi ezindongeni zamakhethini e-aluminium, lapho izinga lokushisa liphezulu nakakhulu. Uma izinga lokushisa elizungezile kanye nomswakama kungekho ngaphakathi kwebanga elinconywayo, kunconywa ukwenza indawo encane yokuhlola ukusetshenziswa kwe-sealant endaweni, bese wenza ukuhlolwa kokunamathela okuxebukayo ukuqinisekisa ukuthi ukunamathela kuhle futhi azikho izimo ezimbi ngaphambi kokukusebenzisa endaweni enkulu.
Ngesikhathi sokufaka isicelo, sicela ulandele lezi zinyathelo ezingezansi:
Uchungechunge lokwakhiwa kwesivali sokwakha (isivali sokwakha sezindonga zamakhethini, isivali sokwakha esinezingqimba ezimbili semigodi, njll.):
1） Hlanza i-substrate
Izinga lokushisa liphezulu ehlobo, futhi isinyibilikisi sokuhlanza kulula ukusishintsha. Naka umthelela emphumeleni wokuhlanza.
2） Faka i-primer (uma kudingeka)
Ehlobo, izinga lokushisa kanye nomswakama kuphezulu, futhi i-primer kulula ukuyikhipha emanzini bese ilahlekelwa umsebenzi wayo emoyeni. Qaphela ukufaka iglue ngokushesha okukhulu ngemva kokusebenzisa i-primer. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inani lezikhathi nesikhathi i-primer ethintana ngaso nomoya kufanele lincishiswe ngangokunokwenzeka. Kungcono ukusebenzisa ibhodlela elincane lokushintshanisa ukuze upakishe.
3） Umjovo we-Sealant
Ngemva kokufakwa kweglue, i-sealant engamelani nesimo sezulu ayikwazi ukufakwa ngokushesha ngaphandle, ngaphandle kwalokho, ijubane lokuphola kwe-structural sealant lizoncishiswa kakhulu.
4） Ukusika
Ngemva kokuphothulwa kokujova ngeglue, ukucheba kufanele kwenziwe ngokushesha, okusiza ukuthi kuhlangane phakathi kwe-sealant nohlangothi lwesixhumi esibonakalayo.
5） Ukuqopha nokumaka
Ngemva kokuba inqubo engenhla isiqediwe, bhala phansi bese umaka ngesikhathi.
6） Ukugcinwa
Iyunithi kumele ilashwe isikhathi esanele ngaphansi kwezimo ezingashintshi futhi ezingacindezelekile ukuqinisekisa ukuthi i-structural sealant inokunamathela okwanele.
Uchungechunge lokwakhiwa kwesivikelo esimelana nesimo sezulu kanye nesivikelo somnyango nefasitela:
1） Ukulungiswa kwamalunga e-Sealant
Induku yefoam ethintana ne-sealant kufanele igcinwe ingashintshi. Izinga lokushisa liphezulu ehlobo, futhi uma induku yefoam yonakele, kulula ukubangela amabala; ngesikhathi esifanayo, kufanele kuqashelwe ukuhambisana kwe-substrate kanye ne-sealant.
2） Hlanza i-substrate
I-glue joint kufanele ihlanzwe endaweni yayo ukuze kususwe uthuli, uwoyela, njll.
3） Faka i-primer (uma kudingeka)
Okokuqala, qiniseka ukuthi ubuso be-substrate ye-glue joint bomile ngokuphelele. Ehlobo, izinga lokushisa kanye nomswakama kuphezulu, futhi i-primer ifakwa kalula emoyeni futhi ilahlekelwa umsebenzi wayo. Kufanele kuqashelwe ukuthi i-glue kufanele ifakwe ngokushesha okukhulu ngemva kokusetshenziswa kwe-primer. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inani nesikhathi sokuxhumana nomoya kufanele kuncishiswe ngangokunokwenzeka. Kungcono ukusebenzisa ibhodlela elincane lokushintshana ukuze upakishe.
4） Umjovo we-Sealant
Kunezimvula eziningi ehlobo. Qaphela ukuthi ngemva kwemvula, i-glue joint kumele yome ngokuphelele ngaphambi kokufaka i-glue.
5） Ukuqeda
Izinga lokushisa ehlobo liphakeme, futhi isikhathi sokuqeda sifushane kunezinye izinkathi zonyaka. Ngemva kokujova ngeglue, ukuqeda kufanele kwenziwe ngokushesha.
6） Ukugcinwa
Esigabeni sokuqala sokulungiswa, akufanele kube nokususwa okukhulu.
Izinkinga ezivamile, Indlela yokubhekana nazo:
1. Isikhathi esifushane sokuphumula kwe-sealant yesakhiwo esinezingxenye ezimbili
Isahlulelo: Isikhathi sekhefu sifushane kunomkhawulo ophansi wesikhathi sekhefu esinconywe umenzi.
Isizathu: Izinga lokushisa eliphezulu kanye nomswakama ehlobo kunciphisa isikhathi sokuphumula.
Isixazululo: Lungisa isilinganiso sezingxenye u-A no-B ngaphakathi kobubanzi obunconywe umenzi.
2. Ukungasebenzi kahle kwe-primer ye-sealant yesakhiwo
Isizathu: Izinga lokushisa eliphezulu kanye nomswakama ehlobo, ukusetshenziswa kabi kwe-primer kungalahlekelwa kalula umsebenzi wayo. I-primer engasebenzi kahle izoholela ekuboshweni okubi kwe-sealant yesakhiwo.
Isixazululo: Kungcono ukusebenzisa amabhodlela amancane njenge-primer. Akukhuthazwa ukusebenzisa i-primer engasetshenziswanga ebhodleleni elincane ubusuku bonke. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inani 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. Isivali sokuvala/isivali somnyango nefasitela esivunguzayo
Indlela yokwahlulela: Kukhona amaqhubu endaweni ebusweni be-silicone sealant. Uma umugqa osuqediwe unqunywa, ingaphakathi liba nembobo.
Isizathu ①: Ubuso benduku yefoam buyabhobozwa ngesikhathi senqubo yokugcwalisa, bese umoya ukhishwa emgodini ngemva kokucindezelwa;
Isixazululo: Uhlangothi lwenduku yefoam oluthintana ne-sealant luhlala lungashintshi. Uma kunzima ukugcwalisa, ungasika ingxenye yangemuva kwenduku yefoam.
Isizathu ②: Ezinye izisekelo zisabela ngezivalo;
Isixazululo: Naka ukuhambisana kwezinhlobo ezahlukene ze-sealant kanye ne-substrates, futhi kudingeka ukuhlolwa kokuhambisana.
Isizathu ③: Ukubhamuka okubangelwa ukwanda kokushisa kwegesi ejoyintini leglue elivalekile;
Isizathu esiqondile kungaba ukuthi kuyo yonke i-glue joint evaliwe, umoya ovalwe ku-glue joint ngemva kokujova uyakhula ngobuningi lapho izinga lokushisa liphezulu (ngokuvamile lingaphezu kuka-15°C), okubangela ukubhoboza ebusweni be-sealant engakaqini.
Isixazululo: Gwema ukuvala ngokuphelele ngangokunokwenzeka. Uma kudingeka, shiya ingxenye encane yemigodi yomoya bese uyigcwalisa ngemva kokuba i-sealant iqina.
Isizathu ④: Isixhumi esibonakalayo noma izinto ezisetshenziswayo zimanzi;
Isixazululo: Ungakhi ngezinsuku zemvula, linda kuze kube yilapho isimo sezulu sicacile futhi i-glue joint yomile.
Isizathu ⑤: Ukwakhiwa ngaphansi kwezimo zokushisa eziphakeme ngaphandle;
Isixazululo: Misa ukwakhiwa ngaphansi kwezimo zokushisa eziphakeme ngaphandle bese ulinda kuze kube yilapho izinga lokushisa lehla ngaphambi kokwakhiwa.
4. Isikhathi esifushane sokulungisa isivalo/isivalo somnyango nefasitela esingamelani nesimo sezulu
Isizathu: Izinga lokushisa nomswakama kuphezulu ehlobo, futhi isikhathi sokudonsa sifushane.
Isixazululo: Ukulungiswa ngesikhathi ngemva kokujova.
Qaphela ngesikhathi sokwakha futhi ulandele imiyalelo ukuqinisekisa ikhwalithi.
Izinga lokushisa eliphezulu kanye nemvula enkulu kuyinselele enkulu, futhi kukhona amaqhinga okwakha i-sealant.
Bhekana nezinkinga ngesikhathi esifanele ukuqinisekisa ukuphepha kwephrojekthi.
I-SIWAY iyahambisana nawe ehlobo elishisayo futhi inika amandla ubuhle ndawonye!
