Silicone structural sealants inogona kumira nehumwe huwandu hwesimba, uye silicone inodzivirira mamiriro ekunze anonamira anonyanya kushandiswa kuvhara mvura. Silicone structural adhesive inogona kushandiswa kune diki-mafuremu uye inogona kumira kumwe kushushikana uye simba rinokwevera zvinhu pasi. Silicone inodzivirira mamiriro ekunze inonamira inongo shandiswa pakuita caulking uye haigone kushandiswa pakusunga chisimbiso.
Silicone Kuvaka Sealant ndeye kwayakarerekera kurapa yakakwirira mhando yekuvaka silicone weatherproof sealant. Yakanakisa kupikisa kwemamiriro ekunze, yakakwirira uye yakadzika tembiricha kuramba -50 ° C + 150 ° C, yakanaka kunamatira, inogona kuwedzeredzwa uye kushandiswa munzvimbo dzakasiyana siyana dzemamiriro ekunze, uye inokurumidza kuita nehunyoro mumhepo, ichirapa kuita yakasimba, Yakakwirira. kuita uye elastic silicone sealant, inogona kuramba kukukurwa kwechisikigo senge okisijeni uye kunhuwa, ultraviolet mwaranzi uye kunaya. Inonyanya kushandiswa kugadzira uye kuvhara magonhi, mahwindo nekushongedza kwekuvaka.
Pakati peakanyanya tekinoroji zviratidzo zvesilicone weather-resistant sealants, iyo sag, extrudability, uye pamusoro pekuomesa nguva inoratidza kuita kwekuvaka. Kuita kweiyo yakarapwa inodzivirira mamiriro ekunze sealant inonyanya kusimuka uye huwandu hwekurasikirwa kwehuwandu. Kurasikirwa kwehuwandu hwekunamira kwemamiriro ekunze kwakafanana nekurasikirwa kwehuremu hwehuremu hwezvinonamira zvechimiro. Inonyanya kuongorora kuchinja kwekushanda kweadhesives-resistant-resistant mushure mekushandisa kwenguva refu. Iyo yakakwirira yehuwandu hwekurasikirwa kwehuwandu, zvakanyanya kuoma kwekuita kunoderera mushure mekushandisa kwenguva refu.
Basa guru resilicone weather-resistant sealant ndeyekusimbisa majoini pakati pemahwendefa. Sezvo mahwendefa anowanzo kukanganiswa nekushanduka kwekushisa uye deformation yechimiro chikuru, hupamhi hwekubatana huchachinjawo. Izvi zvinoda kusungirirwa kwemamiriro ekunze kuti kuve nekwaniso yakanaka yekutsungirira kusimuka kwemajoini, uye haizotsemuka pasi pemamiriro ekuchinja kwenguva refu muhupamhi hwekubatana. zvakasiyana.
Silicone Structural Sealant chinhu chimwe chete, kurapa kwazvakarerekera, chakanyatsogadzirirwa kubatanidza kuungana kwegirazi zvimiro mukuvaka maketeni madziro. Inogona kubudiswa nyore nyore uye inoshandiswa mumhando dzakasiyana-siyana dzekushisa. Vimba nekunyorova mumhepo kurapa kuita yakanakisa, yakasimba yakakwira modulus, yakakwira elasticity silicone rabha. Chigadzirwa hachidi primer kune girazi, uye chinogona kuburitsa yakanakisa adhesion.
Structural adhesive inoreva kusimba kwepamusoro (compressive strength> 65MPa, steel-steel positive tensile bonding simba> 30MPa, shear simba> 18MPa), inokwanisa kushingirira mitoro mikuru, uye inoshingirira kuchembera, kuneta, ngura, uye kuita mukati mehupenyu hunotarisirwa. Yakagadzikana, inokodzera kusimba kwakasimba kwekubatana. Non-structural adhesives ane simba rakaderera uye kusimba kwakashata, uye anogona chete kushandiswa kusungirira, kuisa chisimbiso nekugadzirisa zvinhu zvakajairika uye zvenguva pfupi, uye hazvigone kushandiswa pakugadzirisa hukama.
