Ngati silicone sealant ili ndi zovuta zamtundu, zimabweretsa kutayikira kwamadzi, kutulutsa mpweya ndi zovuta zina, zomwe zingakhudze kwambiri kulimba kwa mpweya komanso kuthina kwamadzi pazitseko ndi mazenera.
Ming'alu ndi kutayikira kwa madzi chifukwa cha kulephera kwa chitseko ndi zenera sealant
Ndiye timasankha bwanji chosindikizira choyenera pazitseko ndi mazenera?
1. Sankhani bwino zinthu zomwe zikugwirizana ndi miyezo
Posankha chosindikizira, chidwi chiyenera kuperekedwa osati ku mulingo womwe umakumana nawo, komanso pamlingo wofananira nawo wakusamuka.Kusuntha kwamphamvu ndiye index yofunikira kwambiri yoyezera kulimba kwa sealant.Kukwera kwa mphamvu yosunthira, kumapangitsanso kusungunuka kwa silicone sealant.Kukonza ndi kukhazikitsa zitseko ndi mazenera ayenera kusankha mankhwala ndi mphamvu kusamutsidwa osachepera 12.5 kuonetsetsa mpweya wothina kwa nthawi yaitali ndi kuthina madzi zitseko ndi mazenera.
Pakuyika ndi kugwiritsa ntchito zitseko ndi mazenera, kulumikizana pakati pa konkriti wamba ndi konkire ya simenti nthawi zambiri kumakhala koyipa kuposa komwe kumakhala ndi mbiri ya aluminiyamu kapena magalasi a zitseko ndi mazenera.Choncho, ndi koyenera kusankha zinthu zogwirizana ndi JC/T 881 monga chosindikizira choyika zitseko ndi mawindo.
Zogulitsa zomwe zimakhala ndi milingo yayikulu yosamuka zimakhala ndi kuthekera kolimba kupirira kusintha kwa kusamuka kwamagulu.Ndibwino kuti tisankhe mankhwala omwe ali ndi msinkhu wapamwamba kwambiri momwe angathere.
2. Sankhanisilikonimankhwala osindikizira molondola malinga ndi cholinga
Mawindo obisika a chimango ndi mafani otsegula obisika amafunikira chosindikizira kuti agwire ntchito yolumikizana.Silicone structural sealant iyenera kugwiritsidwa ntchito, ndipo m'lifupi mwake ndi makulidwe ake ziyenera kukwaniritsa zofunikira pakupanga.
Pakuyika zitseko ndi mazenera, chosindikizira cholumikizira miyala kapena cholumikizira ndi mwala mbali imodzi chizikhala chosindikizira chapadera chamwala chomwe chimakwaniritsa muyezo wa GB/T 23261.
Chotsekera moto ndi choyenera kwambiri pazitseko ndi mazenera osayaka moto kapena zitseko zakunja ndi mazenera a nyumba zomwe zimafuna kukhulupirika kwamoto.
M'malo ogwiritsira ntchito omwe ali ndi zofunikira zapadera zopewera nkhungu, monga khitchini, malo osambira a ukhondo ndi mbali zamdima ndi zonyowa, kusindikiza zitseko ndi zenera ziyenera kugwiritsa ntchito chisindikizo cha nkhungu.
3. Osasankha silicone sealant yodzaza ndi mafuta!
Pakalipano, msika uli wodzaza ndi mafuta ambiri odzaza zitseko ndi mawindo osindikizira, omwe amadzaza ndi mafuta ambiri amchere ndipo amakhala ndi vuto lokalamba, zomwe zingayambitse mavuto ambiri.
Silicone sealant yosakanikirana ndi mafuta amchere amatchedwa "mafuta odzaza silicone sealant" pamsika.Mafuta amchere ndi a saturated alkane petroleum distillation.Chifukwa kapangidwe kake ka maselo ndi kosiyana kwambiri ndi ka silicone, kugwirizana kwake ndi silicone sealant system ndi koyipa, ndipo imasuntha ndikulowa mu silicone sealant pakapita nthawi.Choncho, "mafuta odzaza sealant" ali ndi elasticity yabwino poyamba, koma atatha kugwiritsa ntchito kwa nthawi ndithu, mafuta odzaza mchere amasuntha ndikulowa kuchokera ku sealant, ndipo sealant idzachepa, kuuma, kusweka, ngakhale kukhala ndi vuto la palibe mgwirizano.
Zosindikizira zambiri zotsika mtengo za silicone pamsika zimadzaza ndi mafuta amchere, ndipo zomwe zili mu silicone yoyambira polima ndizochepera 50%, ndipo zina ndizochepera 20%.
Ngati chosindikizira cha zenera lodzaza gasi chilumikizana ndi galasi lotsekera, mafuta odzaza amchere amasuntha ndikulowa mugalasi lotsekera, zomwe zimapangitsa kuti mphira wotsekera wa butyl wagalasi lotsekera komanso kutuluka kwamafuta kuthetsedwa.
Sankhani zosindikizira zapamwamba kwambiri.Ngakhale mtengo wa sealant wogulidwa poyambira ndi wokwera pang'ono, magwiridwe ake amatha kusungidwa kwa nthawi yayitali popanda zovuta.Sankhani "mafuta odzaza sealant" otsika mtengo, ngakhale mtengo wake ndi wotsika mtengo, mtengo woyambira woyambira ndi wotsika pang'ono;Komabe, pakachitika zovuta, ndalama zokonzetsera pambuyo pake, ndalama zogulira, ndalama zogwirira ntchito, kutayika kwamtundu, ndi zina zambiri panthawi yokonzanso zitha kukhala kangapo kapena kangapo mtengo wa chosindikizira chokha;Sizinangopulumutsa ndalama zokha, koma zinawonjezera mavuto ambiri kwa ogwiritsa ntchito.
