Ingaba uyazi? Ebusika, i-sealant yesakhiwo iya kufana neyomntwana, yenza umsindo omncinci, ngoko yintoni ingxaki eya kubangela?
1.I-Structural sealant iphilisa ngokucothayo
Ingxaki yokuqala yokuba ukuhla ngequbuliso kubushushu be-ambient kuzisa kwi-silicone sealants yesakhiwo kukuba baziva becotha ukunyanga ngexesha lokufaka isicelo. Inkqubo yokuphilisa ye-silicone sealant yesakhiwo yinkqubo yokusabela kweekhemikhali, kwaye ubushushu kunye nokufuma kokusingqongileyo kunempembelelo ethile kwisantya sayo sokunyanga. Kwicandelo elinye le-silicone sealants, okukhona ubushushu obuphezulu kunye nokufuma, isantya sokunyanga siya kukhawuleza. Emva kobusika, ukushisa kwehla ngokukhawuleza, kwaye ngexesha elifanayo, kunye nomswakama ophantsi, ukuphendulwa kokunyanga kwe-sealant yesakhiwo kuyachaphazeleka, ngoko ke ukunyangwa kwe-sealant yesakhiwo kuhamba kancane. Phantsi kweemeko eziqhelekileyo, xa iqondo lobushushu lingaphantsi kwe-15 ℃, isenzeko sokucotha ukunyangeka kwesitywina sesakhiwo sibonakala ngakumbi.
Isisombululo: Ukuba umsebenzisi ufuna ukwakha kwindawo yokushisa ephantsi, kuyacetyiswa ukuba aqhube uvavanyo lweglue kwindawo encinci ngaphambi kokusetyenziswa, kwaye aqhube uvavanyo lokunamathela kwi-peel ukuqinisekisa ukuba i-sealant yesakhiwo inokunyangwa, ukubambelela kulungile, kwaye imbonakalo akukho ngxaki uze usebenzise indawo enkulu. Nangona kunjalo, xa ubushushu be-ambient bungaphantsi kwe-4 ° C, ukwakhiwa kwe-sealant yesakhiwo akukhuthazwa. Ukuba i-factory ineemeko, inokuqwalaselwa ngokunyusa ubushushu kunye nomswakama wemo engqongileyo apho i-sealant yesakhiwo isetyenzisiweyo.
2. Iingxaki ze-Structural sealant bonding
Ngokuhla kweqondo lokushisa kunye nomswakama, kunye nokunyangwa okucothayo, kukho nengxaki yokudibanisa phakathi kwe-structural sealant kunye ne-substrate. Iimfuno eziqhelekileyo zokusetyenziswa kweemveliso ze-sealant zesakhiwo zezi: indawo ecocekileyo kunye nobushushu obuphakathi kwe-10 ° C ukuya ku-40 ° C kunye nokufuma okuhambelana ne-40% ukuya kwi-80%. Ukugqithisa iimfuno ezisezantsi zeqondo lokushisa, isantya sokubambisana siyancipha, kwaye ixesha lokudibanisa ngokupheleleyo kwi-substrate lide. Kwangaxeshanye, xa iqondo lobushushu lisezantsi kakhulu, ukumanzi kokuncamathelisa kunye nomphezulu we-substrate kuncipha, kwaye kunokubakho inkungu engabonakaliyo okanye iqabaka kumphezulu we-substrate, echaphazela ukunamathela phakathi kwe-sealant yesakhiwo kunye ne-sealant. isubstrate.
Isisombululo: iqondo lobushushu lingaphantsi kunobuncinane bolwakhiwo lobushushu besakhiwo sealant sealant 10℃, isakhiwo sealant sealant esisiseko semathiriyeli kweyona meko iphantsi yolwakhiwo lweqondo lobushushu ukwenza uvavanyo lwebhondi, qinisekisa ukuhlangana okuhle, emva koko ukwakhiwa. Umzi-mveliso utofe isitywini sesakhiwo, ngokuphucula iqondo lobushushu kunye nokufuma kwemekobume yokusetyenziswa kwe-sealant yesakhiwo ukukhawulezisa ukunyangwa kwe-sealant yesakhiwo, kodwa kufuneka ukwandise ngokufanelekileyo ixesha lokunyanga.
