1. Kupora zvishoma nezvishoma
Dambudziko rekutanga rinounzwa nekudonha kamwe kamwe kwekupisa kwekunzesilicone structural sealantndeyekuti inonzwa yapora panguva yekuisa, uye chimiro chesilicone chakaoma.
Maitiro ekugadzirisa silicone sealant inzira yemakemikari, uye tembiricha nehunyoro hwenzvimbo zvine simba pakumhanya kwayo kwekugadzirisa. Kune chimwe chikamuzvisimbiso zvesilicone zvemukati, kana tembiricha nehunyoro zvikakwira, ndipo panobva pakurumidza kupora. Mushure mechando, tembiricha inodzikira zvakanyanya, uye panguva imwe chete, nekunyorova kushoma, maitiro ekupisa echinhu chinovhara madziro anokanganiswa, saka kupisa kwechinhu chinovhara madziro kunononoka. Mumamiriro ezvinhu akajairwa, kana tembiricha iri pasi pe15 ℃, chiitiko chekupora zvishoma nezvishoma kwechinhu chinovhara madziro chinova pachena.
Mhinduro: Kana mushandisi achida kuvaka munzvimbo ine tembiricha yakaderera, zvinokurudzirwa kuti aite bvunzo ye silicone sealant yenzvimbo diki asati ashandisa, uye aite bvunzo ye peel adhesion kuti asimbise kuti structural sealant inogona kurapwa, glue yacho yakanaka, uye chitarisiko chayo hachina dambudziko. Zvisinei, kana tembiricha yekunze yakaderera se4°C, kuvaka structural sealant hakukurudzirwi.
Chivharo chinonamirwa neglue uchishandisa tembiricha nehunyoro hwenzvimbo yacho.
2. Matambudziko ekubatana
Nekudzikira kwekupisa nehunyoro uye kupera zvishoma nezvishoma, panewo dambudziko rekubatana pakati pechinhu chinovhara madziro nechinhu chiri pasi pevhu. Zvinodiwa zvekushandisasilicone structural sealantzvigadzirwa ndeizvi: nzvimbo yakachena ine tembiricha ye10°C kusvika 40°C uye hunyoro hwe40% kusvika 80%. Kana zvikapfuura zvinodiwa patembiricha yepamusoro zvataurwa pamusoro apa, kumhanya kwekubatanidza kunodzikiswa, uye nguva yekubatana zvizere ne substrate inowedzerwa. Panguva imwe chete, kana tembiricha yakaderera, kunyorova kwenamira nepamusoro pe substrate kunoderera, uye panogona kunge paine mhute kana chando chisingaonekwe pamusoro pe substrate, izvo zvinokanganisa kubatana pakati pe structural sealant ne substrate.
Mhinduro: Kana tembiricha shoma yekuvaka ye structural sealant iri 10 °C, structural sealant inosungirirwa kune substrate mumamiriro ezvinhu chaiwo. Kuedzwa kwekunamatira kunofanirwa kuitwa munzvimbo yekuvaka ine tembiricha yakaderera kusimbisa kunamira kwakanaka usati wavaka. Kupinza structural sealant mufekitori kunogona zvakare kukurumidzisa kugadzika kwe structural sealant nekuwedzera tembiricha nehunyoro hwenzvimbo inoshandiswa structural sealant, uye panguva imwe chete, zvakakosha kuwedzera nguva yekurapwa kwayo zvakakodzera.
3. Wedzera viscosity
Zvisimbiso zvemuumbiZvishoma nezvishoma zvinokora uye zvinoderera kana tembiricha ichidzikira. Kune zvinovhara madziro zvine zvikamu zviviri, zvinovhara madziro zvinowedzera kusimba zvichawedzera kumanikidzwa kwemuchina weglue uye zvinoderedza kubuda kwezvinovhara madziro. Kune zvinovhara madziro zvine zvikamu chimwe chete, zvinovhara madziro zvinokora, kumanikidzwa kwakawedzerwa kwepfuti yeglue kuti ibudise chinovhara madziro kunogona kutora nguva uye kunetesa pakushanda nemaoko.
Mhinduro: Kana pasina mhedzisiro pakushanda zvakanaka kwekuvaka, kukora kwetembiricha yakaderera chinhu chakajairika, uye hapana matanho ekuvandudza anodiwa.
Kana chivakwa chacho chave kushanda, zvinokwanisika kufunga nezvekuwedzera tembiricha yekushanda kwechivakwa kana kutora matanho ekuwedzera ekudziyisa, akadai sekuchengetedza chivakwa mukamuri rekudziyisa kana mukamuri rine mhepo inotonhorera pachine nguva, kuisa hita yekudziyisa muworkshop yekunamatira, uye kuwedzera
