-
Cholakwika pakusakaniza (mu ma silicone a zigawo ziwiri)
Momwe Mungakonzere:
-
--Chotsani silikoni yosakonzedwa bwino.
-
--Gwiritsani ntchito mankhwala atsopano osungidwa pamalo ozizira komanso ouma.
-
--Pa ma silicone ochiritsa chinyezi, onetsetsani kuti chinyezi chili ndi mulingo woyenera (40–70% RH).
-
--Pazinthu ziwiri, tsatirani bwino momwe zinthu zimagwirizanirana (Buku Lothandizira Kuchiritsa Zotsekereza – BSI).
6. Chotsekera Chochotsa Malumikizidwe (Kulephera kwa Malumikizidwe)

Zomatira za silicone ndi zina mwa njira zomatira zolimba kwambiri zomwe zilipo—koma pokhapokha ngati zagwiritsidwa ntchito moyenera.mavuto wamba ndi kukonza kwawo, mutha kuonetsetsa kuti ntchito yanu ikhala yayitali, kuchepetsa kukonza, komanso kuti ntchito yanu ikuyenda bwino.
At Zomatira za Siway, timaperekazomatira za silicone zogwira ntchito kwambiricholinga chake ndi kuchepetsa mavuto awa. Lumikizanani nafegulu lothandizira ukadaulokuti mupeze malangizo okhudza polojekiti.
Q1. N’chifukwa chiyani silicone sealant yanga siimamatira bwino?
Izi nthawi zambiri zimachitika chifukwa chakuipitsidwa pamwamba, chinyezi, kapena kugwiritsa ntchito chosindikizira cholakwika pa substrate. Nthawi zonse yeretsani ndi kuumitsa pamwamba, gwiritsani ntchito chotsukira ngati pakufunika, ndipo sankhani silicone sealant yoyenera yoyeretsera zinthu zofewa monga chitsulo kapena mwala.
Q2. Kodi ndingakonze bwanji thovu kapena mabowo mu silicone sealant?
Kutupa nthawi zambiri kumachitika ngati gawo lapansi lili lonyowa kapena ngati chotsekeracho chagwiritsidwa ntchito mwachangu kwambiri. Chotsani gawo lomwe lalephera, liume bwino, ndikuyikanso mu pulasitiki.mkanda wocheperako, wopitiliraKuti mupeze zotsatira zaukadaulo, onaniASTM C920-18(2024)malangizo ogwiritsira ntchito
Q3. N’chifukwa chiyani silicone sealant imasanduka nkhungu m’bafa?
Ngakhale silicone "yaukhondo" imatha kukhala ndi nkhungu ngati itapezekachinyezi chosalekeza komanso mpweya woipaGwiritsani ntchito silicone sealant yoyera yokhala ndi zowonjezera ku fungicide ndipo sungani malo ouma ngati n'kotheka. Kuyeretsa nthawi zonse ndi zotsukira zosawononga kumathandiza kuti nthawi ya moyo ikhale yayitali.
Q4. Kodi silicone sealant imatenga nthawi yayitali bwanji kuti iume bwino?
Ma silicone ambiri amachiritsa pa2–3 mm patsikukoma kuchira kwathunthu kungatenge mpakaMasiku 7–14, kutengera makulidwe a mikanda, chinyezi, ndi kutentha. Nthawi zonse yang'anani mapepala aukadaulo a wopanga kuti mudziwe nthawi yeniyeni yophikira.
Q5. Kodi ndingagwiritse ntchito silicone yatsopano pa silicone yakale?
Ayi. Silicone yakale iyenera kukhalakuchotsedwa kwathunthuchifukwa chotseka chatsopano sichingamamatire bwino. Gwiritsani ntchito chochotsera chotseka kapena chotsukira chamakina musanayikenso.
Q6. N’chifukwa chiyani silicone sealant yanga yochiritsidwa ikusweka kapena kuchepa?
Izi nthawi zambiri zimachitika chifukwa chakugwiritsa ntchito mtundu wolakwika wa sealant pa malo olumikizirana omwe amayenda kwambirikapena kugwiritsa ntchito mkanda woonda kwambiri. Pa zolumikizira za kapangidwe kake kapena zokulitsa, sankhani silicone sealant yomangidwa yomwe imakwaniritsaMiyezo ya ISO 11600 yoyendetsera kayendedwe.
