Nekuda kwekupisa kushoma munguva yechando, ndeapi matambudziko auchasangana nawo paunoshandisa girazi rinovhara munzvimbo ine tembiricha yakaderera? Pamusoro pezvose, girazi rinovhara chinhu chinonamira kupisa kwekamuri chinokanganiswa zvakanyanya nemamiriro ekunze. Ngatitarisei kushandiswa kwegirazi rinovhara munzvimbo dzine tembiricha yakaderera munguva yechando. Mibvunzo mitatu inowanzo bvunzwa!
1. Kana chivharo chegirazi chikashandiswa munzvimbo ine tembiricha yakaderera, dambudziko rekutanga nderekuti chinononoka kupera
Kupisa nekunyorova kwezvakatipoteredza zvine simba guru pakumhanya kwayo kwekupona. Kune silicone sealants ine chikamu chimwe chete, tembiricha nekunyorova kwakakwira, ndiko kunokurumidza kukurumidza kwekupona. Munguva yematsutso neyechando, tembiricha inoderera zvakanyanya, izvo zvinoderedza mwero wekupona kwesilicone sealant, zvichikonzera nguva yekuomesa pamusoro inononoka uye kupona kwakadzika. Kazhinji, kana tembiricha iri pasi pe15°C, kumhanya kwekupona kunova kunonoka. Kune madziro ejira resimbi, nekuda kwekunonoka kwekupona kwesealant mumatsutso nemuchando, kana musiyano wetembiricha pakati pemasikati neusiku wakakura, mipata iri pakati pemaplate ichatambanudzwa zvakanyanya uye kudzvanywa, uye sealant iri pamajoini ichabukira zviri nyore.
2. Chivharo chegirazi chinoshandiswa munzvimbo dzine tembiricha yakaderera, uye kubatana pakati pegirazi neguruu kuchakanganiswa
Sezvo tembiricha nehunyoro zvichidzikira, kubatana pakati pesilicone sealant nesubstrate kuchakanganiswawo. Kazhinji yakakodzera nharaunda inoshandiswa silicone sealant: zvinhu zviviri zvinofanira kushandiswa munzvimbo yakachena pa10°C~40°C uye hunyoro hwe40%~60%; chinhu chimwe chete chinofanira kushandiswa pa4°C~50°C uye hunyoro hwe40% ~60% munzvimbo dzakachena. Kana tembiricha yakaderera, mwero wekupisa uye reactivity ye sealant inoderera, uye kunyorova kwe sealant nepamusoro pe substrate kunoderera, zvichiita kuti sealant igare kwenguva yakareba ne substrate.
3. Chivharo chegirazi chinoshandiswa munzvimbo dzine tembiricha yakaderera, uye guruu regirazi rinokora
Kana tembiricha yadzikira, silicone sealant inokora zvishoma nezvishoma uye extrudability inoderera. Kune two-component sealants, kukora kwechikamu A kuchaita kuti glue muchina iwedzere, uye glue output inoderera, zvichikonzera glue isingagutsi. Kune one-component sealant, colloid inokora, uye extrusion pressure inenge yakakwira panguva yekushandisa glue gun nemaoko kuderedza kushanda zvakanaka kwemaoko.
Maitiro ekugadzirisa
Kana uchida kuvaka munzvimbo ine tembiricha yakaderera, tanga waita bvunzo yeglue munzvimbo diki kuti uone kuti guruu regirazi rinogona kurapwa, kunamira kwakanaka, uye hapana dambudziko rekuonekwa kweguruu usati wavaka. Kana mamiriro ezvinhu achibvumira, tanga wawedzera tembiricha yenzvimbo yekuvaka usati wavaka.
