Kusukela ngoDisemba, kube nokwehla kwezinga lokushisa emhlabeni jikelele:
Isifunda saseNordic: Isifunda saseNordic saletha amakhaza amakhulu kanye neziphepho zeqhwa ngesonto lokuqala lika-2024, kanye namazinga okushisa aphansi kakhulu angu--43.6℃ kanye no--42.5℃ eSweden naseFinland ngokulandelana. Ngemva kwalokho, umthelela wokwehla okukhulu kwezinga lokushisa wasakazekela eNtshonalanga Yurophu naseCentral Europe, kanti i-United Kingdom kanye neJalimane bakhiphe izexwayiso zesimo sezulu esiphuzi ngenxa yokubanda.
IYurophu Ephakathi NeyaseNingizimu: Izinga lokushisa eYurophu ephakathi naseningizimu nakwezinye izindawo lehle ngo-10 kuya ku-15℃, kanti izinga lokushisa ezindaweni eziphakeme zezintaba lehle ngo-15 kuya ku-20℃. Izinga lokushisa kwezinye izindawo enyakatho yeJalimane, eningizimu yePoland, empumalanga yeCzech Republic, enyakatho yeSlovakia, kanye naseRomania ephakathi lehle kakhulu.
Izingxenye zaseShayina: Izinga lokushisa ezingxenyeni eziningi zaseNyakatho-mpumalanga yeShayina, eningizimu-mpumalanga yeMpumalanga yeShayina, emaphakathi naseningizimu yeShayina, kanye naseningizimu-mpumalanga yeShayina eseningizimu-mpumalanga liphansi kunesikhathi esifanayo seminyaka edlule.
ENyakatho Melika: Izinga lokushisa enyakatho-mpumalanga ye-United States kanye neCanada ephakathi nenyakatho lehle ngo-4 kuya ku-8℃, futhi ladlula ku-12℃ kwezinye izindawo.
Ezinye izingxenye zase-Asia: Izinga lokushisa eRussia ephakathi lehle ngo-6 kuya ku-10℃, futhi ladlula ku-12℃ kwezinye izindawo.
Ukwehla okungazelelwe kwezinga lokushisa nomoya obandayo ovunguzayo kuyahlangana. Njengezinto eziwusizo ezibalulekile ezisetshenziswa kakhulu ekubopheni nasekuvaleni emasimini okwakha izindonga zamakhethini, iminyango namafasitela, ukuhlobisa kwangaphakathi, njll.,izinto zokuvalabasebenza ngenkuthalo kuyo yonke imininingwane. Ngisho nasebusika, abayeki ukusebenza ngenkuthalo ukuze bahlukanise umkhuhlane ngaphandle "kwesithiyo".
Izinga lokushisa elizungezile ebusika liphansi kakhulu, futhi kungase kube nezinkinga ezilandelayo:
(1) Ngaphansi kwezimo zokushisa okuphansi kanye nomswakama ophansi, isivinini sokuqina kanye nesivinini sokubopha sama-sealant esakhiwo se-silicone kuhamba kancane kunokujwayelekile, okuzokwenza isikhathi sokulungisa sibe side futhi kuthinte ukwakhiwa.
(2) Uma izinga lokushisa liphansi kakhulu, ukumanziswa kwe-silicone structural sealants kanye nobuso be-substrate kuyancishiswa, futhi kungase kube nenkungu noma iqhwa elingabonakali ebusweni be-substrate, okuthinta ukunamathela kwe-silicone structural sealants ku-substrate.
Izindlela zokulwa nokwakhiwa kwebusika
Ngakho-ke yini okufanele siyinake ukuze sigweme izinkinga ezingenhla?
Njengamanje, kunezinhlobo ezimbili ze-silicone structural sealant zokwakha ezisetshenziswa ekwakhiweni kodonga lwamakhethini: eyodwa iyi-single-component silicone structural sealant, kanti enye iyi-silicone structural sealant enezingxenye ezimbili. Indlela yokwelapha kanye nezici ezithinta ukuqina kwalezi zinhlobo ezimbili ze-silicone structural sealants ziboniswe kuthebula elingezansi.
| Ingxenye eyodwa | Ingxenye ezimbili |
| Isabela namanzi emoyeni futhi iqina kancane kancane kusukela phezulu kuya ngaphakathi. (Lapho umthungo weglue ujula, kuthatha isikhathi eside ukuwuphola ngokuphelele) | Kuphulukiswa ukusabela kwengxenye A (equkethe inani elincane lamanzi), ingxenye B kanye nomswakama emoyeni, ubuso kanye nengaphakathi kuyaphulukiswa ngasikhathi sinye, isivinini sokupholisa ubuso sishesha kunesivinini sokupholisa kwangaphakathi, kuthintwa usayizi womthungo weglue kanye nesimo sokuvala) |
| Ijubane lokuphehla lihamba kancane kunelezingxenye ezimbili, ijubane alikwazi ukulungiswa, futhi lithinteka kalula yizinga lokushisa elizungezile kanye nomswakama. Ngokuvamile, lapho izinga lokushisa liphansi, ijubane lokuphendula lihamba kancane; lapho umswakama uphansi, ijubane lokuphendula lihamba kancane. | Ijubane lokuphehla liyashesha, futhi ijubane lingalungiswa ngenani lengxenye B. Alithinteki kakhulu umswakama ozungezile futhi lithinteka kakhulu yizinga lokushisa. Ngokuvamile, lapho izinga lokushisa liphansi, kulapho ukuphehla kuhamba kancane. |
Ngokusho kweSigaba 9.1 se-JGJ 102-2013 "Imininingwane Yobuchwepheshe Yobunjiniyela Bodonga Lwekhethini Lengilazi", ukujova i-silicone structural sealant kufanele kwenziwe ngaphansi kwezimo zokushisa okuzungezile kanye nomswakama ezihlangabezana nezimfuneko zomkhiqizo. Isibonelo, izidingo zemvelo zokusetshenziswa kwemikhiqizo ye-siway silicone structural sealant yilezi: indawo ehlanzekile enezinga lokushisa elingu-10℃ kuya ku-40℃ kanye nomswakama ohlobene ongu-40% kuya ku-80%, futhi kugwenywe ukwakhiwa esimweni sezulu esinemvula nesikhithi.
Ekwakhiweni kwasebusika, ukuqinisekisa ukuthi izinga lokushisa lokwakha alikho ngaphansi kuka-10℃, kufanele kuthathwe izinyathelo ezifanele zokushisa. Uma umsebenzisi edinga ukwakha endaweni engaphansi kancane kuka-10℃ ngenxa yezimo ezikhethekile, kunconywa ukuthi aqale enze ukuhlolwa kweglue encane kanye nokuhlolwa kokunamathela ukuze aqinisekise ukuthi imiphumela yokuqina nokubopha kwe-silicone sealant mihle, futhi wandise isikhathi sokulungisa ngokufanele ngokwesimo. Uma kudingeka, cabanga ngokusebenzisa i-xylene ukuhlanza nokusebenzisa i-primer ukukhuthaza isivinini sokubopha nokunciphisa ingozi yokubopha okubi ngenxa yokushisa okuphansi.
Izindlela zokulwa nokuvuvukala kancane
① Thatha izinyathelo ezifanele zokushisa;
② Isivali esinezingxenye ezimbili kufanele siqale sihlolwe ukuthi siyaphuka yini ukuze kutholakale isilinganiso esifanele sokuxuba;
③ I-sealant enengxenye eyodwa idinga ukuhlolwa isikhathi sokomisa ubuso ukuze kutholakale ukuthi ingalapheka yini kule ndawo;
④ Kunconywa ukuthi kwandiswe isikhathi sokupholisa ngemva kokunamathelisa ukuqinisekisa ukuthi i-sealant inesikhathi esanele sokupholisa nokupholisa.
Izindlela zokulwa nokwehluleka kokubopha
① Ukuhlolwa kokunamathela kufanele kwenziwe kusenesikhathi ngaphambi kokwakhiwa, futhi ukwakhiwa kufanele kwenziwe ngokuhambisana nendlela enconywe ukuhlolwa kokunamathela.
② Uma kudingeka, cabanga ngokusebenzisa i-xylene ekuhlanzeni nasekufakeni i-primer ukukhuthaza isivinini sokubopha nokunciphisa ingozi yokubopha okubi okubangelwa ukushisa okuphansi.
③ Ngemva kokufakwa kwe-silicone structural sealant, inqubo yokwelapha kufanele yenziwe endaweni ehlanzekile nenomoya. Uma izinga lokushisa kanye nomswakama wendawo yokwelapha kuphansi, isikhathi sokwelapha sidinga ukwelulwa ngokufanele. Phakathi kwazo, isimo sokwelapha se-single-component structural sealant sinobuhlobo obubalulekile nesikhathi sokwelapha. Ngaphansi kwendawo efanayo, isikhathi sokwelapha siside, izinga lokwelapha liyanda.
Uma kudingeka, kungathathwa izinyathelo zokwandisa izinga lokushisa elizungezile kanye nomswakama. Ukuhlolwa kokugcina kokuthepha irabha kufanele kusetshenziswe njengesisekelo sokunquma ngokugcwele isikhathi sokugcinwa kweyunithi eqediwe. Kuphela ngemva kokuba ukuhlolwa kokuthepha irabha okuqediwe sekufanelekile (bheka isithombe esingezansi) lapho ingafakwa futhi ithuthwe khona.
Njengenye yezinto zokwakha, i-sealant idlala indima ebalulekile futhi ithinta ngqo umsebenzi, impilo yesevisi kanye nenani lesakhiwo, ngakho-ke inqubo yokwakha kumele ilawulwe ngokuqinile uma kusetshenziswa i-glue. Lapho kwakhiwa ebusika nasezimweni zokushisa eziphansi, ukubopha kwangempela kwe-sealant kumele kuqinisekiswe ngokuhambisana nezindinganiso ezifanele ukuqinisekisa ukuthi i-sealant ingaqinisekisa ngempumelelo umphumela wokuvala wesakhiwo. Yasungulwa ngo-1984, iShanghai siway, inamathela enhliziyweni yobuciko, izibophezele ekuhlinzekeni ngezixazululo ze-glue yesistimu yokuvala izindonga zamakhethini okwakha emhlabeni wonke, ingilazi engenalutho, izinhlelo zomnyango namafasitela, i-glue yomphakathi, izakhiwo ezenziwe ngaphambilini kanye nezinkambu zezimboni ezifana namandla, ezokuthutha, ukukhanyisa, izinto zikagesi, ukuxhumana kwe-5G kanye ne-electronics yabathengi, amakhaya ahlakaniphile, izimpahla zikagesi, njll., ukuhola intuthuko ephephile, enempilo, eluhlaza kanye neqhubekayo embonini, nokwenza ukukhetha kwakho okuphelele kusuka emininingwaneni ecashile.
Kulesi sikhathi esibandayo, masinakekele yonke imininingwane ngenhliziyo efudumele ukuqinisekisa ikhwalithi yokwakha kanye nomphumela wezinto zokuvala ze-silicone.
