A. Umswakama ophansi wemvelo
Umswakama ophansi wemvelo kubangela ukuphulukiswa kancane kwe-sealant.Isibonelo, entwasahlobo nasekwindla enyakatho yezwe lami, umswakama womoya ohlobene uphansi, ngezinye izikhathi uhlala cishe ku-30% RH isikhathi eside.
Isixazululo: Zama ukukhetha ukwakhiwa kwesizini ngezinkinga zokushisa nomswakama.
B. Umehluko omkhulu wezinga lokushisa kwemvelo (umehluko wezinga lokushisa oweqile ngosuku olufanayo noma izinsuku ezimbili ezincikene)
Phakathi nenqubo yokwakha, uphiko lokwakha luthemba ukuthi isivinini sokuphulukisa se-sealant kufanele sisheshe ngangokunokwenzeka, ukuze kuncishiswe amathuba okuthintwa yizici zangaphandle.Kodwa-ke, kunenqubo yokwelashwa kwe-sealant, evame ukuthatha izinsuku ezimbalwa.Ngakho-ke, ukuze kusheshiswe isivinini sokuphulukisa seglue, izisebenzi zokwakha zivame ukwenza ukwakhiwa ngaphansi kwezimo ezifanele zokwakha.Ngokuvamile, isimo sezulu (ikakhulukazi izinga lokushisa kanye nomswakama) sikhethelwa ukwakhiwa endaweni yokushisa ezinzile futhi efanelekile ukwakhiwa (igcinwe ezingeni lokushisa elithile kanye nomswakama isikhathi eside).
Isixazululo: Zama ukukhetha isizini nesikhathi esinomehluko omncane wokushisa wokwakha, njengokwakhiwa kwamafu.Ukwengeza, isikhathi sokuphulukisa se-silicone esimelana nesimo sezulu se-sealant sidinga ukuba sifushane, esingaqinisekisa futhi ukuthi i-sealant ngeke isuswe ngamanye amandla angaphandle phakathi nenqubo yokuphulukisa ukuze kubangele ukuba i-glue iqhume.
C. Impahla yephaneli, usayizi kanye nesimo
Ama-substrates aboshwe ngama-sealants ngokuvamile ayingilazi ne-aluminium.Lawa ma-substrates azokhula futhi anciphe ngezinga lokushisa njengoba izinga lokushisa lishintsha, okuzokwenza ukuthi ingcina ibe ngaphansi kokwelula okubandayo nokucindezela okushisayo.
I-coefficient yokunwetshwa komugqa ibizwa nangokuthi i-coefficient yokunwetshwa komugqa.Uma izinga lokushisa lento eqinile lishintsha ngo-1 degree Celsius, isilinganiso sokushintsha kobude bayo kuya kubude bayo ezingeni lokushisa langempela (hhayi ngempela u-0°C) sibizwa ngokuthi “i-coefficient of linear expansion”.Iyunithi ingu-1/℃, futhi uphawu luthi αt.Incazelo yayo ithi αt=(Lt-L0)/L0∆t, okungukuthi, Lt=L0 (1+αt∆t), lapho u-L0 ingusayizi wokuqala wento, u-Lt usayizi wento ku-t ℃, futhi ∆t Umehluko wezinga lokushisa.Njengoba kukhonjisiwe kuleli thebula elingenhla, ubukhulu bepuleti le-aluminum bukhulu, kuba sobala kakhulu ukwenzeka kweglue ekuhlanganyeleni kweglue.Ukuguqulwa okuhlanganyelwe kwepuleti le-aluminium elimise okukhethekile kukhulu kunalelo lepuleti le-aluminium eliyisicaba.
Isixazululo: Khetha ipuleti le-aluminium nengilazi ene-coefficient encane yomugqa wokwandisa, futhi unake ngokukhethekile ohlangothini olude (uhlangothi olufushane) lweshidi le-aluminium.Ukwenziwa kokushisa okusebenzayo noma ukuvikela ipuleti le-aluminium, njengokumboza ipuleti le-aluminium ngefilimu ye-sunshade.Uhlelo "lwezinga lesibili" lungasetshenziselwa ukwakha.
D. Ithonya lamandla angaphandle
Izakhiwo eziphakeme ziyakwazi ukuthonywa yi-monsoon.Uma umoya unamandla, uzokwenza ukuthi i-glue yesimo sezulu iqhume.Amadolobha amaningi ezweni lakithi asendaweni ye-monsoon, futhi izakhiwo zodonga lwamakhethini zizonyakaza kancane ngenxa yokucindezela komoya wangaphandle, okuholela ekushintsheni kobubanzi bamalunga.Uma i-glue isetshenziswa lapho umoya unamandla, i-sealant izoqhuma ngenxa yokugudluzwa kwepuleti ngaphambi kokuba ilapheke ngokuphelele.
Isixazululo: Ngaphambi kokufaka i-glue, isikhundla seshidi le-aluminium kufanele silungiswe ngangokunokwenzeka.Ngesikhathi esifanayo, ezinye izindlela zingasetshenziswa futhi ukwenza buthaka umphumela wamandla angaphandle eshidini le-aluminium.Kuvinjelwe ukusebenzisa i-glue ngaphansi kwesimo somoya omkhulu.
E. ukwakhiwa okungafanele
1. I-glue ehlangene nesisekelo inomswakama ophezulu nemvula;
2. Induku yegwebu iklwejwa ngephutha ngesikhathi sokwakhiwa/ukujula kwenduku yegwebu kuhlukile;
3. Umugqa wegwebu/itheyiphu enamacala akabili ayizange yenziwe isicaba ngaphambi kokulinganisa, futhi yaqhuma kancane ngemva kokulinganisa.Ibonise ukwenzeka kwebhamuza ngemva kokulinganisa.
4. Induku ye-foam ikhethiwe ngokungalungile, futhi i-foam ayikwazi ukuba izinti ze-foam eziphansi, okumele zihambisane nemininingwane efanele;
5. Ubukhulu bosayizi abanele, mncane kakhulu, noma ubukhulu bosayizi abulingani;
6. Ngemuva kokuthi i-substrate ye-splicing isetshenziswe, i-glue ayiqini futhi ihanjiswe ngokuphelele, okubangela ukufuduka phakathi kwama-substrates nokwenza amabhamuza.
7. Iglue esekelwe otshwaleni izoqhuma lapho isetshenziswa ngaphansi kwelanga (lapho izinga lokushisa le-substrate liphezulu).
Isixazululo: Ngaphambi kokwakhiwa, qiniseka ukuthi zonke izinhlobo zama-substrates zisesimweni sokwakhiwa kwezindaba ze-sealant ezingamelana nesimo sezulu, futhi izinga lokushisa nomswakama endaweni nakho kusebangeni elifanele (izimo zokwakha ezinconyiwe).
