Kutheni usenzaizinto zokuvala i-siliconeNgaba unamaxesha ahlukeneyo okomisa umphezulu ebusika nasehlotyeni?
Impendulo: Ngokubanzi, ukoma komphezulu kunye nesantya sokunyanga kweemveliso ze-RTV zokushisa kwegumbi ezinecandelo elinye zinxulumene ngokusondeleyo nokufuma okungqongileyo. Ebusika, xa ukufuma kunye nobushushu buphantsi, i-sealant iya koma kumphezulu kwaye isantya sokunyanga siyacotha. Ehlotyeni, xa ukufuma kuphezulu kwaye ubushushu buphezulu, i-sealant iya koma kwaye iphiliswe ngokukhawuleza.
Ungayifumana njani imveliso ye-silicone sealant enesiqwenga esinye esebenza kakuhle kakhulu?
Impendulo: Iimveliso zerabha zesilicone ezicoca i-condensation ezine-component enye ziyanyangwa ngokusebenzisa ukufuma emoyeni. Xa zinyangwa, ukusuka ngaphandle ukuya ngaphakathi, ngokuqhelekileyo phantsi kweemeko ezingama-25°C kunye ne-50% RH, isilicone inokunyangwa nge-2-3 mm ngosuku, kwaye kuthatha iintsuku ezingaphezu kwe-3 ukufumana iipropati zomzimba ezifanelekileyo.
I-silicone sealant imelana kangakanani nobushushu?
Impendulo: Ngokubanzi, uluhlu lobushushu lwejeli ye-silica yi--40℃-200℃. Ubushushu bokusetyenziswa ixesha elide abukhuthazwa ukuba budlule kwi-150℃. Uluhlu lobushushu lwe-sealant ekhethekileyo enganyangekiyo kubushushu obuphezulu efana ne-silicone ebomvu yentsimbi yi--40℃-250℃. Ubushushu bokusetyenziswa ixesha elide abudluli kwi-180℃. . Ukumelana nobushushu kunxulumene ngokusondeleyo nokuba i-colloid iqine ngokupheleleyo na.
Kutheni i-silicone adhesive sealant ine-viscosity eyahlukileyo ebusika nasehlotyeni?
Impendulo: Ubunzima be-sealant buya kutshintsha xa ubushushu buphezulu. Ehlotyeni, ubunzima buya kuncipha xa ubushushu buphezulu. Ebusika, kukwahlukile, kodwa kuya kuba ngaphakathi komlinganiselo owamkelekileyo.
Indlela yokwandisa isantya sokupholisaisitywini se-silicone?
Impendulo: Xa ubukhulu bokufuma bungaphezulu kwe-6mm, kucetyiswa ukuba ufake i-sealant kabini; ukonyusa ubushushu kunye nokufuma kunokukhawulezisa isantya sokufuma kwemveliso, kodwa ubushushu akufuneki budlule kwi-50°C. Ukonyusa umswakama kungcono kunokunyusa ubushushu.
Ukuba kukho amabala kunye nokufuma kumphezulu we-bonding substrate, ngaba oku kuya kuyichaphazela indlela esebenza ngayo i-sealing?
Ngaphambi kokufaka isitywini, umphezulu we-bonding kufuneka ucocwe ngokupheleleyo ukuze i-sealant inamathele ngokupheleleyo kumphezulu we-bonding. Ukuba kukho ukufuma okanye amabala kumphezulu we-sealant emva kokunyangwa, impembelelo iya kuba ncinci.
