Kodi tiyenera kuganizira chiyani pomanga ma silicone structural sealants m'nyengo yozizira?

Kuyambira Disembala, kutentha kwatsika padziko lonse lapansi:
Chigawo cha Nordic: Chigawo cha Nordic chinayambitsa kuzizira koopsa ndi mphepo yamkuntho mu sabata yoyamba ya 2024, ndi kutentha kwakukulu kwa -43.6 ℃ ndi -42.5 ℃ ku Sweden ndi Finland motsatira. Pambuyo pake, kutsika kwa kutentha kwakukulu kunafalikiranso ku Western Europe ndi Central Europe, ndipo United Kingdom ndi Germany zidapereka zidziwitso zanyengo yachikasu za kuzizira.
Pakati ndi Kumwera kwa Ulaya: Kutentha kwapakati ndi kum'mwera kwa Ulaya ndi malo ena kunatsika ndi 10 mpaka 15 ℃, ndipo kutentha m'madera amapiri okwera kunatsika ndi 15 mpaka 20 ℃. Kutentha m’madera ena a kumpoto kwa Germany, kum’mwera kwa Poland, kum’maŵa kwa Czech Republic, kumpoto kwa Slovakia, ndi pakati pa Romania kunatsika kwambiri.
Mbali za China: Kutentha m'madera ambiri a kumpoto chakum'maŵa kwa China, kum'mwera chakum'maŵa kwa East China, chapakati ndi kum'mwera kwa South China, ndi kum'mwera chakum'maŵa kwa Kumwera chakumadzulo kwa China ndikotsika kuposa nthawi yomweyi ya zaka zapitazo.
Kumpoto kwa America: Kutentha kumpoto chakum’mawa kwa United States ndi chapakati ndi kumpoto kwa Canada kunatsika ndi 4 mpaka 8℃, ndi kupitirira 12℃ m’malo ena.
M’madera ena a ku Asia: Kutentha kwapakati pa Russia kunatsika ndi 6 mpaka 10 ℃, ndipo m’malo ena kunadutsa 12℃.

Chenjezo la kutentha kochepa.2

Kutentha kwadzidzidzi ndi mphepo yoziziritsa yowomba zimasonkhana pamodzi. Monga chinthu chofunikira chothandizira chomwe chimagwiritsidwa ntchito kwambiri pomangirira ndi kusindikiza m'minda yomanga makoma, zitseko ndi mazenera, zokongoletsera zamkati, etc.,zosindikiziragwirani ntchito mwakhama m’mbali zonse. Ngakhale m'nyengo yozizira, samasiya kugwira ntchito mwakhama kuti adzipatula kuzizira kunja kwa "chotchinga".

Kutentha kozungulira m'nyengo yozizira kumakhala kotsika kwambiri, ndipo mavuto otsatirawa amatha kuchitika:


(1) Pansi pa kutentha kochepa komanso chinyezi chochepa, kuthamanga kwa machiritso ndi kuthamanga kwa ma silicone structural sealants ndi pang'onopang'ono kusiyana ndi nthawi zonse, zomwe zimapangitsa kuti nthawi yokonza ikhale yotalikirapo komanso kukhudza zomangamanga.

(2) Pamene kutentha ndi otsika kwambiri, wettability wa silikoni structural sealants ndi gawo lapansi pamwamba yafupika, ndipo pangakhale imperceptible chifunga kapena chisanu pa gawo lapansi, amene amakhudza adhesion wa silikoni structural sealants kwa gawo lapansi.

Zotsutsana ndi zomanga zachisanu

Ndiye tiyenera kusamala ndi chiyani kuti tipewe mavuto omwe tawatchulawa?

Pakalipano, pali mitundu iwiri ya zomangira zomangira za silicon zomwe zimagwiritsidwa ntchito pomanga khoma: imodzi ndi gawo limodzi la silicone structural sealant, ndipo ina ndi zigawo ziwiri za silicone structural sealant. Njira yochiritsira ndi zinthu zomwe zimakhudza kuchiritsa kwa mitundu iwiriyi ya silicone structural sealants ikuwonetsedwa mu tebulo ili m'munsimu.

Chigawo chimodzi

Zigawo ziwiri

Imachita ndi madzi mumlengalenga ndipo imalimba pang'onopang'ono kuchokera pamwamba mpaka mkati. (Kuzama kwa glue, kumatenga nthawi yayitali kuti kuchiritse) Kuchiritsidwa ndi zomwe chigawo A (chokhala ndi madzi pang'ono), chigawo B ndi chinyezi mumlengalenga, pamwamba ndi mkati zimachiritsidwa nthawi yomweyo, kuthamanga kwapamwamba kuchiritsa kuli mofulumira kuposa kuthamanga kwa mkati, komwe kumakhudzidwa ndi kukula kwa msoko wa glue ndi kusindikiza)
Kuthamanga kwa machiritso kumakhala pang'onopang'ono kusiyana ndi magawo awiri, liwiro silingasinthidwe, ndipo limakhudzidwa mosavuta ndi kutentha kozungulira ndi chinyezi. Nthawi zambiri, m'munsi kutentha, ndi pang'onopang'ono anachita liwiro; m'munsi chinyezi, ndi pang'onopang'ono anachita liwiro. Kuthamanga kwa machiritso kumakhala mofulumira, ndipo liwiro likhoza kusinthidwa ndi kuchuluka kwa chigawo B. Sichimakhudzidwa kwambiri ndi chinyezi chozungulira komanso chokhudzidwa kwambiri ndi kutentha. Nthawi zambiri, kutentha kumatsika, kuchira kumachepa.

Malinga ndi Gawo 9.1 la JGJ 102-2013 "Zaukadaulo Zaukadaulo wa Glass Curtain Wall Engineering", jakisoni wa silikoni structural sealant ayenera kuchitidwa pansi yozungulira kutentha ndi chinyezi zinthu mogwirizana ndi mankhwala. mpaka 40 ℃ ndi chinyezi wachibale wa 40% mpaka 80%, ndipo pewani kumanga munyengo yamvula komanso yachisanu.

Pomanga m'nyengo yozizira, kuonetsetsa kuti kutentha kwa zomangamanga sikutsika kuposa 10 ℃, njira zoyenera zotenthetsera ziyenera kuchitidwa. Ngati wogwiritsa ntchito akufunika kupanga malo otsika pang'ono kuposa 10 ℃ chifukwa cha zochitika zapadera, tikulimbikitsidwa kuti tiyese kuyesa kagulu kakang'ono ka guluu ndikuyesa kumamatira kuti mutsimikizire kuti machiritso ndi kugwirizana kwa silicone sealant ndikwabwino, ndikuwonjezera nthawi yosamalira moyenera malinga ndi momwe zinthu zilili. Ngati ndi kotheka, lingalirani kugwiritsa ntchito xylene kuyeretsa ndikugwiritsa ntchito poyambira kuti mulimbikitse kulumikizana mwachangu komanso kuchepetsa chiopsezo cha kusalumikizana bwino chifukwa cha kutentha kochepa.

Njira zotsutsana ndi kuchiritsa pang'onopang'ono

① Tengani njira zotenthetsera zoyenera;
② Zigawo ziwiri zosindikizira ziyenera kuyesedwa kaye kuti zithyoke kuti zitsimikizire kusakaniza koyenera;
③ Chosindikizira chokhala ndi gawo limodzi chimayenera kuyesedwa kuti chiwumitse nthawi kuti chitsimikizire ngati chingachiritsidwe pamalo ano;
④ Ndikofunikira kukulitsa nthawi yochiritsa pambuyo pa gluing kuti zitsimikizire kuti chosindikiziracho chili ndi nthawi yokwanira yochiritsa ndi kuchiritsa.

 

Zotsutsana ndi kulephera kwa mgwirizano

① Mayeso omatira amayenera kuchitidwa pasadakhale asanamangidwe, ndipo ntchito yomanga iyenera kuchitidwa molingana ndi njira yoyeserera yoyeserera.
② Ngati kuli kofunikira, lingalirani kugwiritsa ntchito xylene poyeretsa ndikugwiritsa ntchito poyambira kuti mulimbikitse kulumikizana mwachangu komanso kuchepetsa chiwopsezo cha kugwirizana kosauka chifukwa cha kutentha pang'ono.
③ Pambuyo jekeseni wa silicone structural sealant, kuchiritsa kuyenera kuchitidwa pamalo oyera komanso olowera mpweya. Pamene kutentha ndi chinyezi cha malo ochiritsira ndizochepa, nthawi yochiza iyenera kuwonjezereka moyenerera. Pakati pawo, kuchiritsa kwa gawo limodzi lachimake chosindikizira kumakhala ndi ubale wofunikira ndi nthawi yochiritsa. Pansi pa malo omwewo, nthawi yayitali yochiritsa, imakhala yokwera kwambiri.

Ngati ndi kotheka, zinthu zitha kuchitidwa kuti muwonjezere kutentha ndi chinyezi. Mayeso omaliza a rabara ayenera kugwiritsidwa ntchito ngati maziko odziwa bwino nthawi yokonza gawo lomalizidwa. Pokhapokha ngati mayeso omaliza a rabara atakwaniritsidwa (onani chithunzi pansipa) angayikidwe ndikusamutsidwa.

Monga chimodzi mwa zipangizo zomangira, sealant imagwira ntchito yofunika kwambiri ndipo imakhudza mwachindunji ntchito, moyo wautumiki ndi mtengo wa nyumbayo, choncho ntchito yomangayi iyenera kuyendetsedwa bwino mukamagwiritsa ntchito guluu. Pomanga m'nyengo yozizira komanso yotsika kutentha, kumangiriza kwenikweni kwa chosindikizira kuyenera kutsimikiziridwa molingana ndi miyezo yoyenera kuonetsetsa kuti chosindikiziracho chingathe kutsimikizira kusindikiza kwa nyumbayo. Yakhazikitsidwa mu 1984, Shanghai siway, kumamatira kumtima wamisiri, yadzipereka kupereka njira zosindikizira zomatira pamakoma otchinga padziko lonse lapansi, magalasi opanda pake, mawindo a zitseko ndi mawindo, guluu wamba, nyumba zomangidwa kale ndi mafakitale monga mphamvu, zoyendera, kuyatsa, zida zamagetsi, mauthenga a 5G ndi magetsi ogula, nyumba zanzeru, magetsi, ndi zina zotero, zomwe zimatsogolera makampani kukhala otetezeka, athanzi, obiriwira komanso okhazikika. chitukuko, ndikupanga chisankho chanu changwiro kuchokera mwatsatanetsatane.

Munthawi yozizira ino, tiyeni tisamalire chilichonse ndi mtima wofunda kuti tiwonetsetse kuti zomangira za silicone zimapangidwira komanso momwe zimapangidwira.
