Ngati silicone sealant ili ndi mavuto a khalidwe, izi zingayambitse kutayikira kwa madzi, kutayikira kwa mpweya ndi mavuto ena, zomwe zidzakhudza kwambiri kulimba kwa mpweya ndi kulimba kwa madzi pa zitseko ndi mawindo.
Ming'alu ndi kutayikira kwa madzi chifukwa cha kulephera kwa chitseko ndi zenera
Ndiye tingasankhe bwanji chosindikizira choyenera cha zitseko ndi mawindo?
1. Sankhani bwino zinthu zomwe zikukwaniritsa miyezo
Posankha sealant, chisamaliro chiyenera kuperekedwa osati pa muyezo womwe ikukwaniritsa, komanso pa mulingo wofanana wa displacement. Mphamvu yosinthira ndiyo chizindikiro chofunikira kwambiri poyesa kusinthasintha kwa sealant. Mphamvu yosinthira ikakwera, silicone sealant imasinthasinthanso. Kukonza ndi kukhazikitsa zitseko ndi mawindo kuyenera kusankha zinthu zomwe zimatha kusuntha zosachepera 12.5 kuti zitsimikizire kuti mpweya ndi madzi zikugwira ntchito kwa nthawi yayitali komanso kuti madzi azigwira ntchito bwino.
Pakukhazikitsa ndi kugwiritsa ntchito zitseko ndi mawindo, mphamvu yolumikizirana pakati pa sealant wamba ndi simenti nthawi zambiri imakhala yoipa kuposa ya ma profiles a aluminiyamu kapena magalasi a zitseko ndi mawindo. Chifukwa chake, ndikofunikira kwambiri kusankha zinthu zogwirizana ndi JC/T 881 ngati sealant yokhazikitsira zitseko ndi mawindo.
Zogulitsa zomwe zili ndi malo osunthika kwambiri zimakhala ndi mphamvu yolimba yopirira kusintha kwa malo osunthika. Ndikofunikira kusankha zinthu zomwe zili ndi malo osunthika kwambiri momwe zingathere.
2. Sankhanisilikonizinthu zotsekera bwino malinga ndi cholinga chake
Mawindo obisika a chimango ndi mafani otsegulira chimango chobisika amafunika chosindikizira kuti chigwire ntchito ngati chosindikizira. Chosindikizira cha silicone chiyenera kugwiritsidwa ntchito, ndipo m'lifupi ndi makulidwe ake ziyenera kukwaniritsa zofunikira pa kapangidwe kake.
Pakuyika zitseko ndi mawindo, chosindikizira cha zolumikizira miyala kapena zolumikizira zokhala ndi miyala mbali imodzi chidzakhala chosindikizira chapadera cha miyala chomwe chikukwaniritsa muyezo wa GB/T 23261.
Chotsekera moto ndi choyenera kwambiri pa zitseko ndi mawindo osapsa moto kapena zitseko zakunja ndi mawindo a nyumba zomwe zimafuna kutetezedwa ku moto.
M'malo ogwiritsira ntchito omwe ali ndi zofunikira zapadera zopewera nkhungu, monga kukhitchini, malo osambira aukhondo ndi zinthu zamdima komanso zonyowa, kutseka zitseko ndi mawindo kuyenera kugwiritsa ntchito chotetezera nkhungu.
3. Musasankhe silicone sealant yodzazidwa ndi mafuta!
Pakadali pano, msika uli wodzaza ndi zinthu zambiri zotsekera zitseko ndi mawindo zodzaza ndi mafuta, zomwe zili ndi mafuta ambiri amchere ndipo sizimakalamba bwino, zomwe zingayambitse mavuto ambiri abwino.
Chosindikizira cha silicone chosakanikirana ndi mafuta amchere chimatchedwa "chosindikizira cha silicone chodzazidwa ndi mafuta" mumakampani. Mafuta amchere ndi a saturated alkane petroleum distillation. Chifukwa kapangidwe kake ka molekyulu ndi kosiyana kwambiri ndi ka silicone, kugwirizana kwake ndi makina a silicone sealant sikokwanira, ndipo chimasamuka ndikutuluka mu silicone sealant pakapita nthawi. Chifukwa chake, "chosindikizira chamafuta chodzazidwa ndi mafuta" chimakhala ndi kusinthasintha kwabwino poyamba, koma chikagwiritsidwa ntchito kwa nthawi yayitali, mafuta amchere odzazidwawo amasamuka ndikulowa kuchokera ku chosindikizira, ndipo chosindikiziracho chidzachepa, kuuma, kusweka, komanso kukhala ndi vuto losagwirizana.
Zosefera zambiri za silicone zotsika mtengo pamsika zimakhala ndi mafuta amchere, ndipo kuchuluka kwa silicone basic polymer ndi kochepera 50%, ndipo zina ndizochepera 20%.
Ngati chotseka cha zenera lodzaza mpweya chikakhudzana ndi galasi lotetezera kutentha, mafuta amchere odzazidwawo amasamuka ndikulowa mu galasi lotetezera kutentha, zomwe zimapangitsa kuti mphira wotsekera wa butyl wa galasi lotetezera kutentha usungunuke komanso mafuta amayenda.
Sankhani zinthu zotsekera zapamwamba kwambiri. Ngakhale mtengo wa sealant wogulidwa pachiyambi ndi wokwera pang'ono, magwiridwe ake amatha kusungidwa kwa nthawi yayitali popanda mavuto aubwino. Sankhani "sealant yodzazidwa ndi mafuta" yotsika mtengo, ngakhale mtengo wake ndi wotsika, mtengo woyamba woyika ndalama ndi wotsika pang'ono; Komabe, mavuto atachitika, ndalama zokonzera pambuyo pake, ndalama zogulira, ndalama zogwirira ntchito, kutayika kwa mtundu, ndi zina zotero panthawi yokonzanso zitha kukhala kangapo kapena kangapo mtengo wa sealant yokha; Sikuti sizinangopulumutsa ndalama zokha, komanso zinawonjezera mavuto ambiri kwa ogwiritsa ntchito.
