Kukugwa mvula yambiri kunja, koma mkati mwake pang'ono?
Kodi guluu pa zitseko ndi mawindo kunyumba wasintha mtundu?
Chakuda chimasanduka imvi, khofi imasanduka khaki, zomwe zimakhudza mawonekedwe
Zonsezi zimagwirizana ndi chitseko ndi zenera lotsekeras!
Kugwiritsa ntchito kwakukulu kwa zotsekera zitseko ndi mawindo ndi kutseka pakati pa zitseko ndi mawindo ndi magalasi, komanso kutseka mafelemu a mawindo ndi makoma otsekera. Pakakhala vuto ndi zotsekera zitseko ndi mawindo, zotchingira kutentha, zotchingira phokoso, zotchingira madzi ndi ntchito zina za zitseko ndi mawindo zidzatayika, ndipo zinthu zingapo zomwe zatchulidwa pamwambapa zidzachitika.
Ponena za zotsekera zitseko ndi mawindo, anthu ambiri amaganiza za izi: Chiyani? Kodi si zotsekera magalasi zimenezo? Inde, ndi zotsekera magalasi zomwe zimawonekera kawirikawiri mkamwa mwathu. Koma si zotsekera magalasi zokha.
Nthawi Yotchuka ya Sayansi
Q: N’chifukwa chiyani imatchedwa kuti sealant yagalasi?
Yankho: Chifukwa chakuti silicone sealant yomwe idapangidwa pachiyambi ndi ya asidi ndipo ingagwiritsidwe ntchito kokha kugunda galasi, kotero aliyense amaitcha kuti glass sealant malinga ndi mwambo. Ogula wamba sadziwa zambiri za guluu, kotero aliyense amayamba kuitcha kuti glass sealant.
Q: N’chifukwa chiyani si chosindikizira chagalasi chokha?
Yankho: Chifukwa tsopano chifukwa cha kukula kwachangu kwa makampani opanga rabara la silicone, zotsekera sizinthu zotsekera zokhala ndi acidic zokha, komanso gulu latsopano la zotsekera za silicone zosalowererapo zatulukira. Timagwiritsa ntchito pazitseko ndi mawindo, ndipo zimatchedwa guluu wa chitseko ndi zenera la silicone.
Chotsekera magalasi cha asidi chimagwiritsidwa ntchito kwambiri poteteza madzi ndi kutseka. Choyipa chake ndichakuti chimakhala ndi mphamvu yowononga, kotero zinthu zomwe zingagwiritsidwe ntchito ndizochepa. Kuphatikiza apo, nthawi yonse ya moyo ndi zaka 2 mpaka 3, ndipo n'zosavuta kusweka pambuyo pake; chotsekera magalasi cha neutral chimagwiritsidwa ntchito mosiyanasiyana, sichiwononga, ndipo chimakhala cholimba. Choyipa chake ndichakuti chimachira pang'onopang'ono. Kusankha kwapadera kwa chotsekera kuyenera kutsimikiziridwa kutengera momwe zinthu zilili.
Q: Kodi chotsekera chitseko ndi zenera chimateteza nyengo?
Yankho: Mitundu ya zotsekera zomwe zimagwiritsidwa ntchito pa zitseko ndi mawindo ndi monga: silicone sealant, polyurethane sealant, water-based sealant ndi silane-modified polyether sealant, zomwe silicone sealant ndi yomwe imakondedwa kwambiri. Silicone sealant ili ndi mphamvu yabwino kwambiri yolimbana ndi nyengo, ndipo mphamvu yake yayikulu ya unyolo wa mankhwala ndi yayikulu kuposa mphamvu ya kuwala kwa 300nm ultraviolet, ndichifukwa chake silicone sealant imatha kukhalabe ndi magwiridwe antchito abwino pansi pa kuwala kwa ultraviolet kwa nthawi yayitali.
Mwachitsanzo, tayiwala 666, silicone sealant yothandiza kwambiri pa chilengedwe, ndi yoteteza chilengedwe, kotero kuti imateteza nyengo yake yokha. Chifukwa chake, kaya dzina lake lalembedwa kuti siliteteza nyengo, silinakayikire kuti siliteteza nyengo.
Momwe mungasankhire chosindikizira chitseko ndi zenera
Chotsekera chimangotenga 1-3% ya ndalama zonse zogulira zitseko ndi mawindo osunga mphamvu, koma ubwino wake umakhudza mwachindunji ubwino ndi zotsatira zosungira mphamvu za polojekiti yonse, komanso zimakhudza mwachindunji zomwe timakumana nazo pamoyo wathu. Anthu nthawi zambiri amaganizira kwambiri "zinthu zazikulu" monga galasi ndi ma profiles, ndipo amanyalanyaza zinthu zazing'ono zotsekera. Anthu sadziwa kuti chotsekera zitseko ndi ma windows ndi chinthu chofunikira kwambiri. Kutayika kwa mphamvu komwe kumachitika chifukwa cha kulephera kwa kutseka zitseko ndi ma windows ndi kwakukulu kwambiri kuposa kusunga mphamvu komwe kungapezeke posankha magalasi ndi ma profiles abwino. Kulankhula za kusunga mphamvu ndi kuteteza chilengedwe m'nyumba yomwe imataya mpweya ndi mvula kuli ngati kulankhula zopanda pake.
Kutseka zitseko ndi mawindo kosagwa mvula komanso kosalowa madzi ndi ntchito yokhazikika, monga makoma a nsalu, kuphatikizapo kutseka pakati pa mafelemu a zenera ndi galasi, kutseka pakati pa mafelemu akunja ndi mafelemu a zitseko ndi mawindo, ndi zina zotero. M'chilimwe, dzuwa limakhala lamphamvu ndipo nyengo yoipa monga mphepo yamkuntho ndi mvula yamkuntho imachitika kawirikawiri. Ndi nthawi yoopsa kwambiri ya mavuto a zitseko ndi mawindo. Ndi mavuto ati omwe tiyenera kusamala nawo posankha ndikugwiritsa ntchito silicone sealants pa zitseko ndi mawindo?
1. Sankhani zinthu zomwe zimagwirizana ndi miyezo ya dziko lonse
GB/T 8478-2020 "Zitseko ndi Mawindo a Aluminium Alloy" zimayika patsogolo zofunikira pakutseka ndi kulumikiza zipangizo za zitseko ndi mawindo a aluminiyamu. Kuphatikiza apo, GB/T 14683-2017 "Silicone ndi Modified Silicone Building Sealant", JC/T 881-2017 "Sealant for Concrete Joints", JC/T 485-2007 "Elastic Sealant for Building Windows" ndi miyezo ina imayikanso zizindikiro zoyenera za zotsekera zitseko ndi mawindo a nyumba.
2. Sankhani kampani yayikulu yodalirika
Msika wa guluu wa zitseko ndi mawindo umasakanikirana, ndi mitundu yokhazikika ndi mitundu yotsanzira ikubwera mumtsinje wopanda malire, ndipo palinso zinthu zabodza. Sankhani mtundu waukulu wokhazikika wokhala ndi mphamvu zaukadaulo kuti muchite kafukufuku wa magwiridwe antchito azinthu, kuwongolera mosamala zinthu zopangira ndi njira zopangira, ndipo zinthu zitha kutumizidwa pokhapokha mutayang'anitsitsa magawo, kuti mtunduwo ukhale wotsimikizika.
3. Samalani momwe zinthuzo zimagwirira ntchito
Ponena za kusinthasintha, kuchuluka kwa VOC, zitsulo zolemera, ndi zina zotero za sealant, n'zovuta kwa ogula kuona zizindikiro zilizonse kuchokera ku chinthucho ndi maso awo amaliseche. Ndikofunikira kulabadira ziyeneretso zoteteza chilengedwe za wopanga chinthucho, monga ngati chadutsa dongosolo loyang'anira khalidwe la ISO9001, dongosolo loyang'anira zachilengedwe la ISO14001, dongosolo loyang'anira thanzi ndi chitetezo pantchito la ISO45001, komanso ngati chili ndi satifiketi yovomerezeka yoteteza zachilengedwe ya chipani chachitatu.
4. Kapangidwe koyenera
Silicone sealant imakhudzidwa kwambiri ndi chilengedwe (kutentha ndi chinyezi). Malo ogwiritsidwa ntchito nthawi zonse amafuna kuti igwiritsidwe ntchito pamalo oyera okhala ndi kutentha kwa 5 ~ 40℃ ndi chinyezi cha 40% ~ 80%. Chifukwa chake, sikoyenera kugwiritsa ntchito guluu pamalo opitilira malire omwe ali pamwambapa.
Kuphatikiza apo, ndikofunikira kusamala malo oyera komanso ouma a zitseko ndi mawindo omwe akumangidwa. M'chilimwe, kutentha ndi chinyezi zimakhala zambiri, ndipo chisamaliro chiyenera kuperekedwa pakugwiritsa ntchito guluu mwachangu momwe zingathere (ngati pulasitala ikufunika, ikani guluu mwachangu momwe mungathere mutagwiritsa ntchito pulasitala), ndipo kudula kuyenera kuchitika nthawi yomweyo mukamaliza. Pambuyo pake, iyenera kuchiritsidwa kwa maola opitilira 12 pansi pa mikhalidwe yosasunthika komanso yopanda kupsinjika malinga ndi mikhalidwe yochiritsira ya zinthu zosiyanasiyana.
5. Kusunga koyenera
Kutentha kwambiri komanso chinyezi chambiri zidzafupikitsa kwambiri nthawi yosungiramo zinthu ndikupangitsa kuti zinthuzo zilephereke msanga. Chifukwa chake, tikulimbikitsidwa kugwiritsa ntchito sealant mwachangu mukatsegula nthawi yachilimwe. M'chilimwe, kumakhala chinyezi komanso mvula. Tiyenera kudziwa kuti sealant iyenera kusungidwa pamalo opumira mpweya komanso ozizira okhala ndi malo okwera kuti sealant isagwere mvula kapena ngakhale madzi chifukwa cha nyengo yoipa, zomwe zingakhudze nthawi yosungiramo zinthu ndikuyambitsa mavuto pakulongedza zinthu.
Ogwiritsa ntchito ambiri ali ndi vuto losatseka zitseko ndi mawindo kunyumba, ndipo lingaliro loyamba ndikusintha zitseko ndi mawindo - tsopano tikudziwa kuti izi sizofunikira kwenikweni. Choyamba, onani mosamala ngati guluu wa chitseko ndi zenera wasweka, walimba, kapena wagwira ntchito yosatseka bwino. Ngati vuto lili ndi sealant, ndiye kuti muyenera kungosintha ndi silicone sealant yapamwamba kwambiri yokhala ndi khalidwe lotsimikizika.
