1. Ukwelapha kancane
Inkinga yokuqala ukwehla okungazelelwe kwezinga lokushisa okuletha ku-i-silicone structural sealantukuthi izizwa iphulukisiwe phakathi nenqubo yokufaka isicelo, futhi isakhiwo se-silicone siminyene.
Inqubo yokwelapha ye-silicone sealant iyinqubo yokusabela kwamakhemikhali, futhi izinga lokushisa kanye nomswakama wemvelo kunethonya elithile ejubaneni layo lokuphulukisa.Okwengxenye eyodwaama-silicone sealants structural, lapho izinga lokushisa liphakeme kanye nomswakama, isivinini sokuphulukisa sizoshesha.Ngemuva kobusika, izinga lokushisa lehla kakhulu, futhi ngesikhathi esifanayo, ngomswakama ophansi, ukusabela kokuphulukisa kwe-sealant yesakhiwo kuyathinteka, ngakho ukuphulukiswa kwe-sealant yesakhiwo kuhamba kancane.Ngaphansi kwezimo ezijwayelekile, lapho izinga lokushisa lingaphansi kuka-15 ℃, ukwenzeka kokuphulukiswa kancane kwe-sealant yesakhiwo kubonakala kakhudlwana.
Isixazululo: Uma umsebenzisi efuna ukwakha endaweni yokushisa ephansi, kunconywa ukuthi enze ukuhlolwa kwe-silicone sealant endaweni encane ngaphambi kokusetshenziswa, futhi enze ukuhlolwa kwe-peel adhesion ukuqinisekisa ukuthi i-sealant yesakhiwo ingelapheka, ukunamathela kuhle, futhi ukubukeka akuyona inkinga.indawo esetshenzisiwe.Kodwa-ke, lapho izinga lokushisa le-ambient liphansi njengo-4°C, ukwakhiwa kwe-structural sealant akunconywa.
I-sealant inamathiselwe kusetshenziswa izinga lokushisa kanye nomswakama wemvelo.
2. Izinkinga zokuxhumanisa
Ngokuncipha kwezinga lokushisa kanye nomswakama kanye nokuphulukiswa kancane, kuphinde kube nenkinga yokuhlangana phakathi kwe-structural sealant ne-substrate.Izidingo ezijwayelekile zokusebenzisai-silicone structural sealantimikhiqizo yilena: indawo ehlanzekile enezinga lokushisa elingu-10°C kuya ku-40°C kanye nomswakama ophakathi kuka-40% kuya ku-80%.Ukweqa izimfuneko zokushisa eziphansi ezingenhla, ijubane lokubopha liyancipha, futhi isikhathi sokubopha ngokugcwele ku-substrate siyanwetshwa.Ngesikhathi esifanayo, lapho izinga lokushisa liphansi kakhulu, ukumanzisa kwe-adhesive kanye nobuso be-substrate kuncipha, futhi kungase kube nenkungu engabonakali noma isithwathwa ebusweni be-substrate, ethinta ukunamathela phakathi kwe-sealant yesakhiwo kanye i-substrate.
Isixazululo: Uma izinga lokushisa elincane lokwakha le-sealant yesakhiwo lingu-10 °C, isivalo sesakhiwo siboshelwa ku-substrate esimweni sangempela.Ukuhlolwa kokunamathela kufanele kwenziwe endaweni yokwakhiwa kwezinga lokushisa eliphansi ukuze kuqinisekiswe ukunamathela okuhle ngaphambi kokwakhiwa.Umjovo wasefekthri we-structural sealant ungasheshisa futhi ukuphulukiswa kwe-structural sealant ngokukhuphula izinga lokushisa kanye nomswakama wendawo lapho kusetshenziswa khona i-structural sealant, futhi ngasikhathi sinye, kuyadingeka ukwelula ngokufanelekile isikhathi sokuphulukisa.
3. Khulisa i-viscosity
Ama-sealants esakhiwokancane kancane izoshuba futhi ibe uketshezi oluncane njengoba izinga lokushisa lincipha.Kuma-sealant esakhiwo sezingxenye ezimbili, ama-sealant esakhiwo akhulisa i-viscosity azokwandisa ukucindezela komshini weglue futhi anciphise ukukhishwa kwe-sealant yesakhiwo.Kuma-sealant esakhiwo sengxenye eyodwa, i-structural sealant iyaqina, ingcindezi eyandayo yesibhamu seglue ukuze sikhiphe i-structural sealant singadla isikhathi futhi sikhandlekele imisebenzi eyenziwa ngesandla.
Isixazululo: Uma ungekho umthelela ekusebenzeni kahle kokwakhiwa, ukujiya kwezinga lokushisa eliphansi kuyinto evamile, futhi azikho izinyathelo zokuthuthukisa ezidingekayo.
Uma umphumela wokwakha, kungenzeka ucabangele ukukhulisa izinga lokushisa lokusebenza kwe-structural sealant noma ukuthatha izinyathelo zokushisa ezisizayo, njengokugcina uphawu lwesakhiwo ekamelweni lokushisa noma igumbi eline-air-conditioning kusengaphambili, ukufaka i-heater yokufudumeza ngaphakathi. i-workshop yokunamathisela, nokwandisa
