Kunganiama-silicone sealantsbabe nezikhathi ezihlukene zokomisa phezulu ebusika nasehlobo?
Impendulo: Ngokuvamile, ukoma okungaphezulu nesivinini sokuphulukisa sengxenye eyodwa yokushisa kwegumbi imikhiqizo ye-RTV kuhlobene eduze nomswakamo we-ambient.Ebusika, lapho umswakamo nezinga lokushisa liphansi, isivalo sizokoma kakhulu futhi ijubane lokupholisa lihamba kancane.Ehlobo, lapho umswakama uphezulu futhi izinga lokushisa liphezulu, i-sealant iyoma futhi ilaphe ngokushesha.
Ungafinyelela kanjani ukusebenza okuhle kakhulu kokuphulukisa kwemikhiqizo ye-silicone sealant yengxenye eyodwa?
Impendulo: Imikhiqizo yenjoloba ye-silicone ye-condensation enengxenye eyodwa yelashwa kusetshenziswa umswakama emoyeni.Lapho uphulukisa, kusukela ngaphandle kuya ngaphakathi, ngokuvamile ngaphansi kwezimo ze-25 ° C no-50% RH, i-silicone ingakwazi ukwelapha u-2-3 mm ngosuku, futhi kuthatha izinsuku ezingaphezu kwezingu-3 ukufeza izakhiwo zomzimba ezifanele.
I-silicone sealant imelana kangakanani nezinga lokushisa?
Impendulo: Ngokuvamile, izinga lokushisa lejeli ye-silica lingu-40℃-200℃.Izinga lokushisa lokusetshenziswa kwesikhathi eside alinconywa ukuthi lidlule ku-150 ℃.Ibanga lokushisa le-sealant elikhethekile elimelana nezinga lokushisa eliphezulu njenge-silicone ebomvu yensimbi lingu -40℃-250℃.Izinga lokushisa lokusebenzisa isikhathi eside alidluli ku-180 ℃..Ukumelana nezinga lokushisa kuhlobene eduze nokuthi i-colloid iqiniswe ngokuphelele yini.
Kungani i-silicone adhesive sealant ine-viscosity ehlukile ebusika nasehlobo?
Impendulo: I-viscosity ye-sealant izoshintsha ngokushisa.Ehlobo, i-viscosity izokwehla lapho izinga lokushisa liphezulu.Ebusika, kuphambene nje, kodwa kuyoba ngaphakathi kwebanga elamukelekayo.
Indlela yokwandisa isivinini sokuphulukisai-silicone sealant?
Impendulo: Uma ubukhulu bokuphulukisa bukhulu kuno-6mm, kunconywa ukusebenzisa i-sealant kabili;ukwandisa izinga lokushisa nomswakama kungasheshisa ijubane lokuphulukisa lomkhiqizo, kodwa izinga lokushisa akufanele lidlule ku-50°C.Ukwenyusa umswakama kungcono kunokwenyusa izinga lokushisa.
Uma kukhona amabala nomswakama ebusweni be-substrate ebophayo, ingabe kuzothinta ukusebenza kokuvala?
Ngaphambi kokufaka i-sealant, indawo yokubopha idinga ukuhlanzwa ngokugcwele ukuze i-sealant ikwazi ukunamathela ngokugcwele endaweni yokubopha.Uma kunomswakama noma amabala endaweni ye-sealant ngemva kokwelapha, umthelela uzoba mncane kakhulu.
