Kuyambira mu Disembala, kutentha kwakhala kukutsika padziko lonse lapansi:
Chigawo cha Nordic: Chigawo cha Nordic chinayambitsa kuzizira kwambiri ndi chimphepo chamkuntho mlungu woyamba wa 2024, ndi kutentha kochepa kwambiri kwa -43.6℃ ndi -42.5℃ ku Sweden ndi Finland motsatana. Pambuyo pake, kuchepa kwakukulu kwa kutentha kunafalikira ku Western Europe ndi Central Europe, ndipo United Kingdom ndi Germany zinapereka machenjezo achikasu okhudza kuzizira.
Pakati ndi Kum'mwera kwa Europe: Kutentha kwapakati ndi kum'mwera kwa Europe ndi malo ena kunatsika ndi 10 mpaka 15℃, ndipo kutentha kwa m'mapiri okwera kwambiri kunatsika ndi 15 mpaka 20℃. Kutentha kwa m'madera ena kumpoto kwa Germany, kum'mwera kwa Poland, kum'mawa kwa Czech Republic, kumpoto kwa Slovakia, ndi pakati pa Romania kunatsika kwambiri.
Mbali za China: Kutentha m'madera ambiri a kumpoto chakum'mawa kwa China, kum'mwera chakum'mawa kwa China, pakati ndi kum'mwera kwa South China, komanso kum'mwera chakum'mawa kwa China kuli kotsika kuposa nthawi yomweyi ya zaka zam'mbuyomu.
North America: Kutentha kumpoto chakum'mawa kwa United States ndi pakati ndi kumpoto kwa Canada kunatsika ndi 4 mpaka 8℃, ndipo kunapitirira 12℃ m'malo ena.
Madera ena a ku Asia: Kutentha kwapakati pa Russia kunatsika ndi 6 mpaka 10℃, ndipo kunapitirira 12℃ m'malo ena.
Kutsika kwadzidzidzi kwa kutentha ndi mphepo yozizira zimalumikizana. Monga chinthu chofunikira chothandizira chomwe chimagwiritsidwa ntchito kwambiri pomanga makoma a nsalu, zitseko ndi mawindo, zokongoletsera zamkati, ndi zina zotero,zomatiraamagwira ntchito mwakhama m'mbali zonse. Ngakhale m'nyengo yozizira, sasiya kugwira ntchito mwakhama kuti athetse kuzizira kunja kwa "chotchinga".
Kutentha kwa mlengalenga m'nyengo yozizira kumakhala kotsika kwambiri, ndipo mavuto otsatirawa angachitike:
(1) Pa kutentha kochepa komanso chinyezi chochepa, liwiro lolimba komanso liwiro lomangirira la zomangira za silicone zimakhala zocheperako kuposa masiku onse, zomwe zimapangitsa kuti nthawi yokonza ikhale yayitali ndikukhudza kapangidwe kake.
(2) Kutentha kukakhala kotsika kwambiri, kunyowa kwa silicone structural sealants ndi substrate surface kumachepa, ndipo pakhoza kukhala chifunga kapena chisanu chosawoneka pamwamba pa substrate, zomwe zimakhudza kumamatira kwa silicone structural sealants ku substrate.
Njira zothanirana ndi zomangamanga m'nyengo yozizira
Ndiye kodi tiyenera kusamala ndi chiyani kuti tipewe mavuto omwe ali pamwambapa?
Pakadali pano, pali mitundu iwiri ya zomangira za silicone zomwe zimagwiritsidwa ntchito popanga makoma a nsalu: imodzi ndi silicone structural sealant yokhala ndi gawo limodzi, ndipo inayo ndi silicone structural sealant yokhala ndi magawo awiri. Njira yophikira ndi zinthu zomwe zimakhudza kuchiritsa kwa mitundu iwiriyi ya silicone structural sealants zawonetsedwa patebulo pansipa.
| Chigawo chimodzi | Zigawo ziwiri |
| Imakumana ndi madzi mumlengalenga ndipo imauma pang'onopang'ono kuchokera pamwamba kupita mkati. (Msoko wa guluu ukazama kwambiri, umatenga nthawi yayitali kuti uume bwino) | Kuchira ndi momwe gawo A limachitira (lomwe lili ndi madzi ochepa), gawo B ndi chinyezi mumlengalenga, pamwamba ndi mkati zimachira nthawi imodzi, liwiro la kuchira pamwamba limathamanga kuposa liwiro la kuchira mkati, lomwe limakhudzidwa ndi kukula kwa msoko wa guluu ndi momwe zimatsekedwera) |
| Liwiro la kuchira ndi locheperako kuposa la magawo awiri, liwiro silingasinthidwe, ndipo limakhudzidwa mosavuta ndi kutentha ndi chinyezi cha mlengalenga. Kawirikawiri, kutentha kukakhala kotsika, liwiro la kuchitapo kanthu limachepa; chinyezi chikakhala chotsika, liwiro la kuchitapo kanthu limachepa. | Liwiro la kuchira ndi lachangu, ndipo liwiro likhoza kusinthidwa ndi kuchuluka kwa gawo B. Silikhudzidwa kwambiri ndi chinyezi cha mlengalenga ndipo limakhudzidwa kwambiri ndi kutentha. Kawirikawiri, kutentha kukakhala kotsika, kuchira kumakhala kochedwa. |
Malinga ndi Gawo 9.1 la JGJ 102-2013 "Mafotokozedwe Aukadaulo a Uinjiniya wa Khoma la Magalasi", Kuikapo silicone structural sealant kuyenera kuchitika pansi pa kutentha ndi chinyezi chozungulira chomwe chikugwirizana ndi zomwe zafotokozedwa mu malonda. Mwachitsanzo, zofunikira zachilengedwe zogwiritsira ntchito zinthu za siway silicone structural sealant ndi izi: malo oyera okhala ndi kutentha kwa 10℃ mpaka 40℃ ndi chinyezi cha 40% mpaka 80%, ndikupewa kumanga munyengo yamvula komanso chipale chofewa.
Mu nthawi yozizira yomanga, kuti kutentha kwa nyumbayo kusapitirire 10℃, njira zoyenera zotenthetsera ziyenera kutengedwa. Ngati wogwiritsa ntchito akufunika kumanga pamalo otsika pang'ono kuposa 10℃ chifukwa cha zochitika zapadera, akulimbikitsidwa kuti choyamba achite mayeso ang'onoang'ono a guluu ndi mayeso omatira kuti atsimikizire kuti zotsatira za silicone sealant zikulimba komanso zomatira ndi zabwino, ndikuwonjezera nthawi yokonza malinga ndi momwe zinthu zilili. Ngati pakufunika kutero, ganizirani kugwiritsa ntchito xylene kuyeretsa ndikugwiritsa ntchito primer kuti mulimbikitse liwiro la mgwirizano ndikuchepetsa chiopsezo cha mgwirizano woipa chifukwa cha kutentha kochepa.
Njira zothanirana ndi kuchira pang'onopang'ono
① Chitani njira zoyenera zotenthetsera;
② Chotsekera cha zigawo ziwiri chiyenera kuyesedwa kaye kuti chiwone ngati chasweka kuti chidziwe chiŵerengero choyenera cha kusakaniza;
③ Chotsekera cha chinthu chimodzi chiyenera kuyesedwa kuti chiwone ngati chingaume pamwamba kuti chidziwike ngati chingachiritsidwe pamalo awa;
④ Ndikofunikira kuwonjezera nthawi yothira pambuyo pomatira kuti chotsekeracho chikhale ndi nthawi yokwanira yothira ndi kuthira.
Njira zothanirana ndi kulephera kwa mgwirizano
① Kuyesa kumatirira kuyenera kuchitika pasadakhale kusanayambe kumanga, ndipo kumanga kuyenera kuchitika motsatira njira yomwe yalangizidwa ndi mayeso omatirira.
② Ngati kuli kofunikira, ganizirani kugwiritsa ntchito xylene poyeretsa ndikugwiritsa ntchito primer kuti mulimbikitse liwiro la ma bonding ndikuchepetsa chiopsezo cha ma bonding osalimba chifukwa cha kutentha kochepa.
③ Pambuyo poti silicone structural sealant yabayidwa, njira yophikira iyenera kuchitika pamalo oyera komanso opumira mpweya. Pamene kutentha ndi chinyezi cha malo ophikira chili chochepa, nthawi yophikira iyenera kukulitsidwa moyenera. Pakati pawo, momwe chimaphikira cha single-component structural sealant chilili ndi ubale wofunikira ndi nthawi yophikira. Pansi pa malo omwewo, nthawi yophikira ikatalika, mlingo wa chimachikira umakwera.
Ngati pakufunika kutero, njira zitha kuchitidwa kuti kutentha ndi chinyezi ziwonjezeke. Kuyesa komaliza kwa rabala kuyenera kugwiritsidwa ntchito ngati maziko odziwira nthawi yosamalira chipangizo chomalizidwa. Kuyesa komaliza kwa rabala kuyenera kuyikidwa ndikunyamulidwa pokhapokha ngati mayeso omaliza avomerezedwa (onani chithunzi pansipa).
Monga chimodzi mwa zipangizo zomangira, sealant imagwira ntchito yofunika kwambiri ndipo imakhudza mwachindunji ntchito, moyo wautumiki ndi kufunika kwa nyumbayo, kotero njira yomangira iyenera kuyendetsedwa mosamala pogwiritsa ntchito guluu. Pomanga nthawi yozizira komanso kutentha kochepa, kulumikizana kwenikweni kwa sealant kuyenera kutsimikiziridwa motsatira miyezo yoyenera kuti zitsimikizire kuti sealant ikhoza kutsimikizira bwino momwe nyumbayo imagwirira ntchito. Kampani yomwe idakhazikitsidwa mu 1984, Shanghai siway, ikutsatira mfundo zaukadaulo, yadzipereka kupereka njira zomatira zomatira pamakoma a nsalu yotchinga padziko lonse lapansi, magalasi opanda kanthu, zitseko ndi mawindo, guluu wamba, nyumba zomangidwa kale ndi mafakitale monga mphamvu, mayendedwe, magetsi, zida zamagetsi, kulumikizana kwa 5G ndi zamagetsi, nyumba zanzeru, magetsi, ndi zina zotero, kutsogolera chitukuko chotetezeka, chathanzi, chobiriwira komanso chokhazikika m'makampani, ndikupanga chisankho chanu chabwino kuchokera kuzinthu zobisika.
Mu nyengo yozizira ino, tiyeni tisamalire chilichonse ndi mtima wofunda kuti tiwonetsetse kuti kapangidwe kake ndi kagwiritsidwe ntchito ka silicone sealants.
