Mukudziwa? M'nyengo yozizira, chosindikizira cha structural chidzakhala ngati cha mwana, zomwe zimapangitsa kuti munthu akwiye pang'ono, ndiye kuti chidzabweretsa mavuto otani?
1. Chotsekera cha kapangidwe kake chimachiritsa pang'onopang'ono
Vuto loyamba lomwe kutsika kwadzidzidzi kwa kutentha kwa mlengalenga kumabweretsa ku structural silicone sealant ndikuti zimachedwa kuchira panthawi yogwiritsa ntchito. Njira yochiritsira ya structural silicone sealant ndi njira yochitira mankhwala, ndipo kutentha ndi chinyezi cha chilengedwe zimakhudza liwiro lake lochira. Kwa structural silicone sealants imodzi, kutentha ndi chinyezi zikakwera, liwiro la kuchira lidzakhala lofulumira. Pambuyo pa nyengo yozizira, kutentha kumatsika kwambiri, ndipo nthawi yomweyo, ndi chinyezi chochepa, kuchira kwa structural sealant kumakhudzidwa, kotero kuchira kwa structural sealant kumakhala kochedwa. Muzochitika zachizolowezi, kutentha kukakhala kotsika kuposa 15 ℃, chochitika cha kuchira pang'onopang'ono kwa structural sealant chimakhala chodziwikiratu.
Yankho: Ngati wogwiritsa ntchito akufuna kumanga pamalo otentha pang'ono, akulangizidwa kuti ayesere guluu m'dera laling'ono musanagwiritse ntchito, ndikuchita mayeso omatira peel kuti atsimikizire kuti structural sealant ikhoza kuchiritsidwa, kuti structural sealant ndi yabwino, ndipo mawonekedwe ake si vuto kenako nkugwiritsa ntchito malo akuluakulu. Komabe, kutentha kwa mlengalenga kuli kotsika kuposa 4°C, sikuvomerezeka kumanga structural sealant. Ngati fakitale ili ndi mikhalidwe yoyenera, ikhoza kuganiziridwa powonjezera kutentha ndi chinyezi cha malo omwe structural sealant imagwiritsidwa ntchito.
2. Mavuto ogwirizana ndi kapangidwe ka sealant
Ndi kuchepa kwa kutentha ndi chinyezi, limodzi ndi kuuma pang'onopang'ono, palinso vuto la kugwirizana pakati pa structural sealant ndi substrate. Zofunikira zonse pakugwiritsa ntchito zinthu zotsekera structural ndi izi: malo oyera okhala ndi kutentha kwa 10°C mpaka 40°C komanso chinyezi cha 40% mpaka 80%. Kupitirira zomwe zili pamwambapa, liwiro la structural sealant limachepetsedwa, ndipo nthawi yolumikizana kwathunthu ndi substrate imatalikitsidwa. Nthawi yomweyo, kutentha kukakhala kochepa kwambiri, kunyowa kwa guluu ndi pamwamba pa substrate kumachepa, ndipo pakhoza kukhala chifunga kapena chisanu chosawoneka bwino pamwamba pa substrate, zomwe zimakhudza kugwirizana pakati pa structural sealant ndi substrate.
Yankho: kutentha kuli kotsika kuposa kutentha kochepa kwa kapangidwe kake ka structural sealant 10℃, zinthu zoyambira za kapangidwe kake ka structural sealant bonding mu malo enieni otentha kwambiri kuti achite mayeso omangirira, kutsimikizira mgwirizano wabwino, kenako kumanga. Fakitale yaikamo structural sealant, mwa kusintha kutentha ndi chinyezi cha malo ogwiritsira ntchito structural sealant kuti ifulumizitse kuuma kwa structural sealant, komanso imafunika kutalikitsa nthawi youma moyenera.
