Nekuda kwekushisa kwakadzika munguva yechando, ndeapi matambudziko auchasangana nawo kana uchishandisa girazi sealant munzvimbo yakaderera tembiricha? Mushure mezvose, girazi sealant tembiricha yekamuri inorapa inonamira iyo inokanganiswa zvakanyanya nenharaunda. Ngatitarisei kushandiswa kwegirazi glue munzvimbo yechando yakaderera tembiricha. 3 mibvunzo yakajairika!
1. Kana girazi sealant richishandiswa munzvimbo yakaderera tembiricha, dambudziko rekutanga rinononoka kurapa
Tembiricha nekunyorova kwemhoteredzo kune imwe pesvedzero pakukurumidza kurapa kwayo. Kune imwe-chikamu silicone sealants, iyo yakakwira tembiricha uye hunyoro, inokurumidza kukurumidza kurapa. Mumwaka wematsutso nemwaka wechando, tembiricha inodonha zvakanyanya, izvo zvinoderedza kurapa kwekuita chiyero chesilicone sealant, zvichikonzera kunonoka kuomeswa kwepasi uye kurapa kwakadzika. Kazhinji, kana tembiricha yakadzikira kupfuura 15°C, kukurumidza kurapa kunova kunonokera. Kune simbi yesimbi yemaketeni madziro, nekuda kwekunonoka kuporeswa kwechisimbiso mukuvhuvhu uye munguva yechando, kana tembiricha musiyano pakati pemasikati neusiku wakakura, mikaha pakati pemahwendefa ichatambanudzwa zvakanyanya nekumanikidzwa, uye chisimbiso pamajoini chichaita. kuputika nyore.
2. Girazi sealant rinoshandiswa munzvimbo yakaderera tembiricha, uye kubatana pakati pegirazi glue ne substrate kuchakanganiswa.
Sezvo tembiricha uye hunyoro zvinodzikira, kunamatira pakati pesilicone sealant uye substrate kuchakanganiswawo. Kazhinji inokodzera zvakatipoteredza iyo silicone sealant inoshandiswa: maviri-chikamu chinofanira kushandiswa munzvimbo yakachena pa10 ° C ~ 40 ° C uye hunyoro hunyoro 40% ~ 60%; imwe-chikamu inofanira kushandiswa pa 4 ° C ~ 50 ° C uye hunyoro hunyoro 40% ~ 60% inoshandiswa munzvimbo dzakachena dzakapoteredza. Kana tembiricha yakadzikira, chiyero chekuporesa uye reactivity yechisimbiso chinodzikira, uye kunyorova kwechisimbiso uye pamusoro peiyo substrate kunoderera, zvichikonzera nguva yakareba yekuti chisimbiso chiite chisungo chakanaka ne substrate.
3. Girazi sealant inoshandiswa munzvimbo yakadzika yekushisa, uye girasi glue rinowedzera
Sezvo tembiricha inodzikira, iyo silicone sealant inokora zvishoma nezvishoma uye iyo extrudability inova murombo. Kune maviri-chikamu sealants, kukora kwechikamu A kuchaita kuti kumanikidzwa kwemushini weglue kuwedzere, uye kuburitsa glue kunoderera, zvichikonzera glue isingafadzi. Kune imwe-chikamu sealant, iyo colloid yakakora, uye extrusion pressure yakakwira zvakanyanya panguva yekugadzira nemaoko kushandisa glue pfuti kuderedza kushanda kwemaoko.
Kugadzirisa sei
Kana iwe uchida kuvaka munzvimbo yakaderera-kupisa, tanga waita diki-nzvimbo glue test kuti usimbise kuti girazi glue rinogona kuporeswa, kunamatira kwakanaka, uye hapana dambudziko rekuonekwa risati ravakwa.Kana mamiriro achibvumidza, tanga kuwedzera kuwedzera. tembiricha yenzvimbo yekuvaka isati yavakwa
