Silicone sealant sezvayaishandiswa zvakanyanya mumhando dzese dzezvivakwa. Zvinhu zvekushongedza zvemukati nekunze zvemaketeni zvakagamuchirwa nemunhu wese.
Zvisinei, nekukura nekukurumidza kwekushandiswa kwesilicone sealant muzvivakwa, matambudziko anokanganisa mashandiro uye kuchengetedzeka kwezvivakwa zvinoenderana nazvo anoonekwa zvishoma nezvishoma.
Saka, zvakakosha kusimbisa kunzwisisa mashandiro echigadzirwa chesilicone sealant.
Silicone sealant yakavakirwa pa polydimethylsiloxane sechinhu chikuru chisina kucheneswa, ichiwedzerwa ne crosslinking agent, filler, plasticizer, coupling agent, catalyst mu vacuum mixed paste, patembiricha yemukamuri kuburikidza nemvura iri mumhepo inofanira kusimbiswa kuti igadzire rabha ye silicone inonamira.
Silicone sealant rudzi rwegirazi nezvimwe zvinhu zvekutanga zvekubatanidza nekuvhara. Kune mapoka maviri makuru: silicone sealant uye polyurethane sealant (PU).
Silicone sealant ine acetic uye neutral mhando mbiri (neutral sealant yakakamurwa kuita: stone sealant, anti-fungus sealant, fire sealant, pipeline sealant, nezvimwewo); Zvakadai seOLV 168 neOLV 128, dzine mashandisirwo akasiyana.
OLV168 acetic silicone sealant inokurumidza kuvhurika patembiricha yemumba, thixotropic, haina kuyerera, inoramba kukwegura zvakanaka, inoramba mafuta, inoramba mvura, inoramba acid zvishoma, inoramba alkali zvakanyanya, inoramba tembiricha yakakwira neyakaderera, inogona kushandiswa munzvimbo dziri pakati pe -60℃ ~ 250℃, ine kuvharwa kwakanaka, inoramba kuvhunduka uye inoramba kukanganiswa.
Acetic inonyanya kushandiswa pakubatanidza magirazi nezvimwe zvinhu zvekuvaka. Neutral inokunda hunhu hwezvinhu zvesimbi zvine acid corrosion uye reaction nezvinhu zvealkaline, saka ine mhando dzakasiyana dzekushandiswa, uye mutengo wayo wemusika wakakwira zvishoma pane acid. Rudzi rwakakosha rwe neutral pamusika i structural silicone sealant, nekuti inoshandiswa zvakananga mu curtain wall metal negirazi structure kana non-structural bonding assembly, saka zvinodiwa zvemhando yepamusoro uye giredhi rechigadzirwa ndizvo zvakanyanya mu glass glue, mutengo wayo wemusika ndiwo wakanyanyawo.
