Kutentha kukakwera kwambiri ndipo mvula ikapitirira, sikuti imangokhudza kupanga kwa fakitale yathu, komanso makasitomala ambiri akuda nkhawa kwambiri ndi kusungidwa kwa zotsekera.
Silicone sealant ndi rabala ya silicone yosungunuka kutentha kwa chipinda. Ndi phala lopangidwa ndi rabala ya silicone 107 ndi filler ngati zinthu zazikulu zopangira, zowonjezera ndi crosslinking agent, thixotropic agent, coupling agent, ndi catalyst mu vacuum state. Imayanjana ndi madzi mumlengalenga ndikulimba kuti ipange rabala ya silicone yosalala.
Zinthu zosungira silicone zimakhala ndi zofunikira kwambiri pa malo osungira. Malo osungiramo zinthu osakwanira amachepetsa magwiridwe antchito a silicone sealant, kapena kuipangitsa kukhala yolimba. Pa milandu yoopsa, magwiridwe antchito a mbali ina ya silicone sealants amatayika, ndipo chinthucho chidzatayidwa.
Tiyeni tikambirane za malangizo ena osungira zinthu zomatira za silicone.
Mu malo otentha kwambiri, silicone sealant imafulumizitsa ukalamba, imapangitsa kuti zinthu zina zichepe, imachepetsa kutayika kwa zinthu zina, ndikufupikitsa nthawi yosungira. Chifukwa chake, kutentha kosungira kumakhudza kwambiri ubwino wa silicone sealant, ndipo kutentha kosungirako sikuyenera kupitirira 27°C (80.6°F).
Mu malo otentha kwambiri, kutentha kochepa kwambiri kwa mlengalenga kungapangitse kuti cholumikizira cholumikizira ndi cholumikizira mu guluu wa silicone ziume. Makristalowa amapangitsa kuti guluu asawoneke bwino komanso zowonjezera zosafanana. Mukapanga kukula, colloid imatha kuchiritsidwa m'deralo koma osati kuchiritsidwa m'deralo. Chifukwa chake, silicone sealant yopangidwa ndi crystallized singagwiritsidwe ntchito. Pofuna kupewa kuti rabara ya silicone isaume, malo osungira sayenera kukhala otsika kuposa -5°C (23℉).
Mu malo okhala ndi chinyezi chambiri, silicone sealant imauma ikakumana ndi nthunzi ya madzi. Chinyezi chikachuluka m'malo osungira, silicone sealant imachira mwachangu. Ma silicone sealant ambiri amapanga kuchuluka kwa ma sealant ouma miyezi 3-5 mutapanga, zomwe zimagwirizana mwachindunji ndi chinyezi cha malo osungiramo zinthu chomwe chili chokwera kwambiri, ndipo ndikofunikira kwambiri kufunikira kuti chinyezi cha malo osungiramo zinthu chikhale ≤70%.
Mwachidule, zinthu za rabara za silicone ziyenera kusungidwa pamalo ouma, opumira mpweya, komanso ozizira. Kutentha kwabwino kosungirako kuli pakati pa -5 ndi 27°C (23--80.6℉), ndipo chinyezi chabwino kwambiri chosungirako ndi ≤70%. Sizimasungidwa m'malo omwe ali ndi mphepo, mvula, komanso dzuwa. Munthawi yoyendera komanso yosungira, nthawi yosungira ndi miyezi yosachepera 6 kuyambira tsiku lopangidwa.
Pofuna kupewa kuwonongeka kwa khalidwe la zinthu za silicone rabara panthawi yosungira, nyumba yosungiramo zinthu iyenera kukhala pamalo ozizira popanda kuwala kwa dzuwa mwachindunji. Sizothekanso kusankha malo otsika omwe madzi amatha kusonkhana. Kwa nyumba zosungiramo zinthu zomwe zimakhala ndi kutentha kwambiri, tiyenera kuchita bwino ntchito yoziziritsa denga. Nyumba yosungiramo zinthu yokhala ndi kutentha kwa kutentha padenga ndiyo yabwino kwambiri, ndipo iyenera kukhala ndi mpweya wokwanira nthawi yomweyo. Ngati zinthu zilola, nyumba yosungiramo zinthu ili ndi zoziziritsira mpweya ndi zochotsera chinyezi kuti nyumba yosungiramo zinthu ikhale ndi kutentha kofanana komanso chinyezi nthawi yachilimwe ndi nyengo yamvula.
