Kusukela ngoDisemba, kube khona ukwehla kwezinga lokushisa emhlabeni jikelele:
Isifunda saseNordic: Isifunda saseNordic sangenisa amakhaza amakhulu neziphepho zezulu ngeviki lokuqala lika-2024, ngamazinga okushisa aphansi kakhulu -43.6℃ kanye -42.5℃ eSweden naseFinland ngokulandelana. Kamuva, umthelela wokwehla okukhulu kwezinga lokushisa wasakazekela eNtshonalanga Yurophu naseCentral Europe, futhi i-United Kingdom neJalimane yakhipha izexwayiso zesimo sezulu esiphuzi mayelana nokuqandisa.
I-Europe Emaphakathi neseNingizimu: Izinga lokushisa enkabeni naseningizimu yeYurophu nakwezinye izindawo lehle ngo-10 kuya ku-15℃, futhi izinga lokushisa ezindaweni eziphakeme zezintaba lehla ngo-15 kuya ku-20℃. Izinga lokushisa kwezinye izindawo enyakatho yeJalimane, eningizimu yePoland, empumalanga yeCzech Republic, enyakatho yeSlovakia, nasenkabeni yeRomania lehla kakhulu.
Izingxenye zaseShayina: Izinga lokushisa ezindaweni eziningi zeNyakatho-mpumalanga yeChina, eningizimu-mpumalanga ye-East China, enkabeni naseningizimu ye-South China, naseningizimu-mpumalanga ye-Southwest China liphansi kunesikhathi esifanayo seminyaka edlule.
ENyakatho Melika: Izinga lokushisa enyakatho-mpumalanga ye-United States nasenkabeni nasenyakatho yeCanada lehle ngo-4 laya ku-8℃, futhi ledlula ku-12℃ kwezinye izindawo.
Ezinye izingxenye zase-Asia: Izinga lokushisa enkabeni yeRussia lehle ngo-6 laya ku-10℃, futhi ladlula ku-12℃ kwezinye izindawo.
Ukwehla kwezinga lokushisa kungazelelwe nomoya obandayo ohelezayo kuyahlangana. Njengento ebalulekile eyisizayo esetshenziswa kabanzi ekubopheni nasekuvaleni emikhakheni yokwakha izindonga zamakhethini, iminyango namafasitela, umhlobiso wangaphakathi, njll.,ama-sealantssebenza ngenkuthalo kuyo yonke imininingwane. Ngisho nasebusika, abalokothi bayeke ukusebenza ngokuzikhandla ukuze bahlukanise amakhaza ngaphandle “kwesithiyo”.
Izinga lokushisa le-ambient ebusika liphansi kakhulu, futhi kungase kuvele izinkinga ezilandelayo:
(1) Ngaphansi kwezinga lokushisa eliphansi nezimo zomswakama ophansi, isivinini sokuphulukisa kanye nesivinini sokubopha ama-silicone structural sealants kuhamba kancane kunokujwayelekile, okuzokwenza ukuthi isikhathi sokunakekela sibe side futhi sithinte ukwakhiwa.
(2) Uma izinga lokushisa liphansi kakhulu, ukumanzisa kwezivalo zesakhiwo se-silicone kanye nendawo engaphansi kuyancishiswa, futhi kungase kube nenkungu engabonakali noma isithwathwa endaweni engaphansi, ethinta ukunamathela kwezinsimbi zesakhiwo se-silicone ku-substrate.
Izinyathelo zokulwa nokwakhiwa kwebusika
Ngakho yini okufanele siyinake ukuze sigweme izinkinga ezingenhla?
Njengamanje, kunezinhlobo ezimbili zama-silicone sealant structural sealant asetshenziswa ekwakhiweni kodonga lwamakhethini: enye iyi-single-component silicone structural sealant, kanti enye iyizingxenye ezimbili ze-silicone structural sealant. Indlela yokwelapha kanye nezici ezithinta ukuphulukiswa kwalezi zinhlobo ezimbili zama-silicone sealant structural sealant kukhonjisiwe etafuleni elingezansi.
| Ingxenye eyodwa | Ingxenye ezimbili |
| Isabela ngamanzi emoyeni futhi iqina kancane kancane ukusuka phezulu kuya ngaphakathi. (Uma ujula umthungo weglue, kuthatha isikhathi eside ukwelapha ngokugcwele) | Iphulukiswa ukusabela kwengxenye A (equkethe inani elincane lamanzi), ingxenye B kanye nomswakama emoyeni, indawo engaphezulu nangaphakathi yelashwa ngesikhathi esifanayo, ijubane lokuphulukisa elingaphezulu liyashesha kunejubane lokuphulukisa langaphakathi, elithintekayo ubukhulu bomthungo weglue kanye nesimo sokuvala) |
| Isivinini sokuphulukisa sihamba kancane kunaleso sezingxenye ezimbili, isivinini asikwazi ukulungiswa, futhi sithinteka kalula izinga lokushisa elizungezile kanye nomswakama. Ngokuvamile, lapho izinga lokushisa liphansi, ijubane lokusabela liyancipha; lapho umswakama uphansi, ijubane lokusabela liyancipha. | Isivinini sokuphulukisa siyashesha, futhi isivinini singashintshwa ngenani lengxenye B. Akuthintwa kancane umswakama we-ambient futhi kuthintwa kakhulu izinga lokushisa. Ngokuvamile, lapho izinga lokushisa liphansi, liyancipha ukuphulukiswa. |
NgokweSigaba 9.1 se-JGJ 102-2013 "Izicaciso Zobuchwepheshe Ze-Glass Curtain Wall Engineering", umjovo we-silicone structural sealant kufanele wenziwe ngaphansi kwezimo ze-ambient nezimo zomswakama ezihlangabezana nezimfuneko zomkhiqizo. Isibonelo, izidingo zemvelo zokusetshenziswa kwemikhiqizo ye-silicone yesakhiwo sealant yilezi: indawo ehlanzekile enezinga lokushisa elingu-10 ℃ ukuya ku-40℃ kanye nomswakama ohlobene no-40% kuya ku-80%, futhi ugweme ukwakhiwa esimweni sezulu esinemvula neqhwa.
Ekwakhiweni kwasebusika, ukuze kuqinisekiswe ukuthi izinga lokushisa lokwakha alikho ngaphansi kuka-10 ℃, izinyathelo ezifanele zokushisa kufanele zithathwe. Uma umsebenzisi edinga ukwakha endaweni engaphansi kuka-10 ℃ ngenxa yezimo ezikhethekile, kuyanconywa ukuthi aqale enze ukuhlolwa kweglue esezingeni elincane kanye nokuhlola ukunamathela ukuze kuqinisekiswe ukuthi ukuphulukiswa nokubopha imiphumela ye-silicone sealant mihle, futhi andise ngokufanelekile isikhathi sokunakekela ngokwesimo. Uma kunesidingo, cabanga ukusebenzisa i-xylene ukuze uhlanze futhi ufake i-primer ukuze ukhuthaze isivinini sokubopha futhi unciphise ingcuphe yokungahlangani kahle ngenxa yezinga lokushisa eliphansi.
Izinyathelo zokulwa nokwelapha kancane
① Thatha izinyathelo ezifanele zokushisisa;
② I-sealant enezingxenye ezimbili kufanele iqale ihlolwe ukuthi iphukile ukuze kunqunywe isilinganiso esifanele sokuxutshwa;
③ Isivalo sengxenye eyodwa sidinga ukuhlolwa isikhathi sokumisa phezulu ukuze kunqunywe ukuthi singelapheka yini kule ndawo;
④ Kunconywa ukuthi kunwetshwe isikhathi sokuphulukisa ngemuva kokunamathisela ukuze kuqinisekiswe ukuthi i-sealant inesikhathi esanele sokuphulukisa nokuphulukisa.
Izinyathelo eziphikisanayo zokwehluleka kwesibopho
① Ukuhlolwa kokunamathela kufanele kwenziwe kusenesikhathi ngaphambi kokwakhiwa, futhi ukwakhiwa kufanele kwenziwe ngokuqinile ngokuhambisana nendlela enconywe ukuhlolwa kokunamathela.
② Uma kunesidingo, cabanga ukusebenzisa i-xylene ukuhlanza nokusebenzisa i-primer ukuze ukhuthaze isivinini sokubopha futhi unciphise ubungozi bokuhlangana okubi okubangwa izinga lokushisa eliphansi.
③ Ngemuva kokuthi i-silicone structural sealant ijovwe, inqubo yokwelapha kufanele yenziwe endaweni ehlanzekile nengenamoya. Lapho izinga lokushisa kanye nomswakama wendawo yokwelapha kuphansi, isikhathi sokuphulukisa sidinga ukunwetshwa ngendlela efanele. Phakathi kwazo, isimo sokwelapha se-sealant yesakhiwo esisodwa sinobudlelwane obubalulekile nesikhathi sokuphulukisa. Ngaphansi kwendawo efanayo, isikhathi eside sokuphulukisa, izinga lokuphulukisa liyakhuphuka.
Uma kunesidingo, izinyathelo zingathathwa zokwandisa izinga lokushisa lendawo kanye nomswakama. Ukuhlolwa kokugcina kokuthinta iraba kufanele kusetshenziswe njengesisekelo sokunquma ngokugcwele isikhathi sokugcinwa kweyunithi eqediwe. Kuphela ngemva kokuba ukuhlolwa kokuthepha kwenjoloba okuqediwe sekufanelekile (bheka umfanekiso ongezansi) lapho ingafakwa futhi ithuthwe.
Njengenye yezinto zokwakha, i-sealant idlala indima ebalulekile futhi ithinta ngokuqondile umsebenzi, impilo yesevisi kanye nenani lesakhiwo, ngakho-ke inqubo yokwakha kufanele ilawulwe ngokuqinile uma usebenzisa i-glue. Lapho kwakhiwa ebusika nezimo zokushisa eziphansi, ukubopha kwangempela kwe-sealant kufanele kuqinisekiswe ngokuhambisana nezindinganiso ezifanele ukuze kuqinisekiswe ukuthi i-sealant ingaqinisekisa ngempumelelo umphumela wokuvala wesakhiwo. Yasungulwa ngo-1984, i-Shanghai siway, ibambelela enhliziyweni yobungcweti, izibophezele ekuhlinzekeni izixazululo zeglue zokuvala izindonga zamakhethini omhlaba wonke, ingilazi engenalutho, izinhlelo zeminyango namafasitela, i-civil glue, izakhiwo ezakhiwe ngaphambili nezimboni ezifana namandla, ezokuthutha, ukukhanyisa, izinto zikagesi, ezokuxhumana ze-5G nezinto zikagesi zabathengi, amakhaya ahlakaniphile, izinsiza zikagesi, njll., okuholela embonini ephephile, enempilo, eluhlaza futhi eqhubekayo ukuthuthukiswa, nokwenza ukukhetha kwakho okuphelele kusuka emininingwaneni ecashile.
Kule nkathi ebandayo, masinakekele yonke imininingwane ngenhliziyo efudumele ukuze siqinisekise ikhwalithi yokwakha kanye nomthelela wama-silicone structural sealant.
