M'zaka zaposachedwa, pakhala nyengo yoipa kwambiri padziko lonse lapansi, zomwe zayesanso makampani athu osindikizira, makamaka mafakitale aku China monga ife omwe amatumiza kumadera onse adziko lapansi.
M’masabata angapo apitawa ku China, kugwa mvula kosalekeza ndi kutentha kwakukulu sikusiya mpata wopumula. Ndiye momwe mungayikitsire zosindikizira moyenera pamalo otentha komanso chinyezi chambiri?
1 Kuyika ndi kusungirako zosindikizira
Popeza kuti zosindikizira ndi mankhwala, njira yochiritsira ndiyo kuchitapo kanthu ndi kulimba mukakumana ndi chinyezi. Akaviikidwa m'madzi, zoyikapo zakunja zosindikizira zimatha kugwira ntchito yotchinga pang'ono. Choncho, m'chilimwe, zosindikizira ziyenera kusungidwa pamalo okwera kwambiri, mpweya wabwino komanso ozizira kuti zisindikizo zisamalowe mumvula kapena ngakhale kuzimitsidwa m'madzi chifukwa cha nyengo yoipa, zomwe zidzakhudza nthawi ya alumali ya mankhwala ndi chifukwa. kuthetsa mavuto mu phukusi lazinthu.
Zosindikizira zoviikidwa m'madzi ziyenera kusunthidwa kutali ndi malo otsekemera mwamsanga ndikupita kuchipinda chowuma ndi mpweya wabwino. Katoni yoyikapo yakunja iyenera kuchotsedwa, pamwamba iyenera kupukuta ndi kuikidwa m'nyumba kuti igwiritsidwe ntchito posachedwa.
2 Njira yolondola yogwiritsira ntchito sealant
Musanagwiritse ntchito, chonde tcherani khutu ku izi:
Kufunika kwa kutentha kozungulira kwa mtundu wa Siwaysilicone sealantZogulitsa ndi: 4 ℃～40 ℃, malo oyera okhala ndi chinyezi cha 40% ~80%.
M'madera ena kusiyana ndi zomwe zili pamwambapa kutentha ndi chinyezi, ogwiritsa ntchito sakulimbikitsidwa kugwiritsa ntchito sealant.
M'chilimwe, kutentha kwakunja kumakhala kwakukulu, makamaka kwa makoma a aluminiyamu yotchinga, kumene kutentha kumakhala kokwera kwambiri. Ngati kutentha kozungulira ndi chinyezi sikuli mkati mwazovomerezeka, tikulimbikitsidwa kuti muyese kagawo kakang'ono ka mayeso a sealant pamalopo, ndikuyesa kuyesa kwamadzimadzi kuti mutsimikizire kuti zomatirazo ndizabwino ndipo palibe zovuta zomwe zisanachitike. kuzigwiritsa ntchito pamlingo waukulu.
Mukamagwiritsa ntchito, chonde tsatirani izi:
Kapangidwe ka sealant yomangika (zosindikizira zomangira makoma a nsalu zotchinga, zosindikizira zamitundu iwiri zamabowo, ndi zina zotero):
1) Yeretsani gawo lapansi
Kutentha kumakhala kotentha kwambiri m'chilimwe, ndipo zosungunulira zoyeretsera zimakhala zosavuta kusungunuka. Samalani ndi zotsatira za kuyeretsa.
2) Ikani zoyambira (ngati pakufunika)
M'chilimwe, kutentha ndi chinyezi ndizokwera, ndipo choyambira chimakhala chosavuta kutsitsa hydrolyze ndikutaya ntchito yake mumlengalenga. Samalani jekeseni guluu mwamsanga mukatha kugwiritsa ntchito poyambira. Nthawi yomweyo, ziyenera kudziwidwa kuti mukatenga choyambira, kuchuluka kwa nthawi ndi nthawi yomwe primer imalumikizana ndi mpweya iyenera kuchepetsedwa momwe mungathere. Ndibwino kugwiritsa ntchito botolo laling'ono lachiwongoladzanja poyikapo.
3） Jakisoni wa sealant
Pambuyo pa jekeseni ya guluu, chosindikizira chosagwirizana ndi nyengo sichingagwiritsidwe ntchito nthawi yomweyo kunja, apo ayi, liwiro la machiritso la chosindikizira chokhazikika lidzachepetsedwa kwambiri.
4) Kuchepetsa
Pambuyo jekeseni ya guluu ikamalizidwa, kudula kuyenera kuchitika nthawi yomweyo, zomwe zimathandizira kulumikizana pakati pa chosindikizira ndi mbali ya mawonekedwe.
5） Kujambulitsa ndikuyika chizindikiro
Ndondomeko yomwe ili pamwambayi ikamalizidwa, lembani ndikuyika chizindikiro mu nthawi.
6） Kusamalira
Chigawocho chiyenera kuchiritsidwa kwa nthawi yokwanira pansi pazikhalidwe zosasunthika komanso zosasunthika kuti zitsimikizire kuti chosindikizira chokhazikika chimakhala ndi zomatira zokwanira.
Kapangidwe ka sealant yolimbana ndi nyengo komanso chitseko ndi zenera:
1) Kukonzekera kophatikizana kosindikizira
Ndodo ya thovu yomwe ikukhudzana ndi chosindikizira iyenera kukhala yosasunthika. Kutentha kumakhala kotentha m'chilimwe, ndipo ngati ndodo ya thovu yawonongeka, n'zosavuta kuyambitsa matuza; panthawi imodzimodziyo, chidwi chiyenera kuperekedwa ku kugwirizanitsa kwa gawo lapansi ndi sealant.
2） Yeretsani gawo lapansi
Gulu la guluu liyenera kutsukidwa m'malo kuti lichotse fumbi, mafuta, ndi zina.
3) Ikani zoyambira (ngati pakufunika)
Choyamba, onetsetsani kuti pamwamba pa guluu olowa gawo lapansi ndi youma kwathunthu. M'chilimwe, kutentha ndi chinyezi ndizokwera kwambiri, ndipo choyambiracho chimapangidwa mosavuta ndi hydrolyzed mumlengalenga ndikutaya ntchito yake. Zindikirani kuti guluu liyenera kubayidwa posachedwa pambuyo poyambira. Panthawi imodzimodziyo, ziyenera kukumbukiridwa kuti potenga primer, chiwerengero ndi nthawi yokhudzana ndi mpweya ziyenera kuchepetsedwa momwe zingathere. Ndibwino kugwiritsa ntchito botolo laling'ono lachiwongoladzanja poyikapo.
4） Jakisoni wa sealant
Kumakhala mabingu ambiri m'chilimwe. Zindikirani kuti mvula ikatha, guluu liyenera kukhala louma musanabaye guluu.
5) Kumaliza
Kutentha m'chilimwe ndipamwamba, ndipo nthawi yomaliza imakhala yochepa kusiyana ndi nyengo zina. Pambuyo pa jekeseni ya guluu, kumaliza kuyenera kuchitika nthawi yomweyo.
6） Kusamalira
Kumayambiriro kwa kukonza, sikuyenera kukhala kusuntha kwakukulu.
Mavuto wamba, Momwe mungathanirane nawo:
1. Nthawi yopuma yochepa ya zigawo ziwiri za structural sealant
Chigamulo: Nthawi yopuma ndi yayifupi kuposa malire otsika a nthawi yopuma yomwe wopanga amavomereza.
Chifukwa: Kutentha kwakukulu ndi chinyezi m'chilimwe zimafupikitsa nthawi yopuma.
Yankho: Sinthani chiŵerengero cha zigawo A ndi B mkati mwa mulingo womwe wopanga amalimbikitsa.
2. Kusagwira ntchito kwa structural sealant primer
Chifukwa: Kutentha kwambiri ndi chinyezi m'chilimwe, kugwiritsa ntchito koyambirira kosayenera kumatha kutaya ntchito zake. Kusagwira ntchito koyambirira kumapangitsa kuti pakhale kusalumikizana bwino kwa zosindikizira zamapangidwe.
Yankho: Ndi bwino kugwiritsa ntchito mabotolo ang'onoang'ono poyambira. Sitikulimbikitsidwa kugwiritsa ntchito choyambira chosagwiritsidwa ntchito mu botolo laling'ono usiku wonse. Panthawi imodzimodziyo, ziyenera kukumbukiridwa kuti potenga primer, chiwerengero ndi nthawi yolumikizana pakati pa primer ndi mpweya ziyenera kuchepetsedwa momwe zingathere. Ndipo yang'anani mawonekedwe a primer mu botolo laling'ono mu nthawi. Ngati mawonekedwe asintha chifukwa cha nthawi yayitali yosungira, choyambira mu botolo laling'ono sichiyenera kugwiritsidwa ntchito.
3. Weathering sealant / chitseko ndi zenera sealant kubwebweta
Njira yoweruza: Pali zotupa zam'deralo pamwamba pa silicone sealant. Mzere wochiritsidwawo ukatsegulidwa, mkati mwake muli dzenje.
Chifukwa ①: Pamwamba pa ndodo ya thovu imakhomeredwa panthawi yodzaza, ndipo mpweya umatuluka mu dzenje pambuyo pofinyidwa;
Yankho: Mbali ya ndodo ya thovu yokhudzana ndi chosindikizira imakhalabe. Ngati kuli kovuta kudzaza, mukhoza kudula mbali ya kumbuyo kwa ndodo ya thovu.
Chifukwa ②: Magawo ena amachitira ndi zosindikizira;
Yankho: Samalani kuyanjana kwa mitundu yosiyanasiyana ya zosindikizira ndi magawo, ndipo mayeso ofananira amafunikira.
Chifukwa ③: Kubowoleza chifukwa matenthedwe kukula kwa mpweya mu losindikizidwa guluu olowa;
Chifukwa chenichenicho chingakhale chakuti pagulu lonse lotsekedwa la guluu, mpweya wotsekedwa mu guluu wolumikizana pambuyo jekeseni umakula kwambiri pamene kutentha kuli kwakukulu (nthawi zambiri pamwamba pa 15 ° C), kuchititsa kuphulika pamwamba pa chosindikizira chomwe sichinafikebe. zolimba.
Yankho: Pewani kusindikiza kwathunthu momwe mungathere. Ngati ndi kotheka, siyani kagawo kakang'ono ka mabowo otulukira mpweya ndikudzaza pambuyo pa sealant solidifies.
Chifukwa ④: Mawonekedwe kapena zowonjezera ndizonyowa;
Yankho: Osamanga pamasiku amvula, dikirani mpaka nyengo ikhale bwino ndipo guluu liuma.
Chifukwa ⑤: Kumanga pansi pa kutentha kwakukulu panja;
Yankho: Imitsani ntchito yomanga kunja kwa kutentha kwakukulu ndikudikirira mpaka kutentha kutsika musanamangidwe.
4. Kukonza kwakanthawi kochepa kwa sealant yosagwirizana ndi nyengo / chitseko ndi zenera
Chifukwa: Kutentha ndi chinyezi zimakhala zambiri m'chilimwe, ndipo nthawi yokoka imafupikitsidwa.
Yankho: Konzani pakapita nthawi mutatha jekeseni.
Samalani panthawi yomanga ndikutsatira malangizo kuti muwonetsetse kuti zili bwino.
Kutentha kwakukulu ndi mvula yambiri ndizovuta kwambiri, ndipo pali zidule zomangira sealant.
Yang'anani ndi zovuta munthawi yake kuti mutsimikizire chitetezo cha polojekiti.
SIWAY imakuperekezani nthawi yotentha ndikupatsa mphamvu kukongola limodzi!
