1. Ukupholisa kancane
Inkinga yokuqala ebangelwa ukwehla okungazelelwe kwezinga lokushisa elizungezileisivalo sesakhiwo se-siliconeukuthi izwakala ipholile ngesikhathi senqubo yokufaka, futhi isakhiwo se-silicone siqinile.
Inqubo yokwelapha ye-silicone sealant iyinqubo yokusabela kwamakhemikhali, futhi izinga lokushisa kanye nomswakama wendawo kunomthelela othile esivinini sayo sokwelapha. Kwengxenye eyodwaizinto zokuvala ze-silicone zesakhiwo, uma izinga lokushisa nomswakama kuphakeme, isivinini sokupholisa sizoba sishesha kakhulu. Ngemva kobusika, izinga lokushisa lehla kakhulu, futhi ngesikhathi esifanayo, ngomswakama ophansi, ukusabela kokupholisa kwe-structural sealant kuyathinteka, ngakho-ke ukupholisa kwe-structural sealant kuhamba kancane. Ngaphansi kwezimo ezivamile, lapho izinga lokushisa liphansi kune-15 ℃, isimo sokupholisa kancane kwe-structural sealant sisobala kakhulu.
Isixazululo: Uma umsebenzisi efuna ukwakha endaweni enezinga lokushisa eliphansi, kunconywa ukuthi enze isivivinyo se-silicone sealant endaweni encane ngaphambi kokusebenzisa, futhi enze isivivinyo sokunamathela kwe-peel ukuqinisekisa ukuthi i-structural sealant ingalapheka, ukunamathela kuhle, futhi ukubukeka kwayo akunankinga. Kodwa-ke, uma izinga lokushisa elizungezile liphansi njengo-4°C, ukwakhiwa kwe-structural sealant akukhuthazwa.
I-sealant inamathiselwa nge-glue kusetshenziswa izinga lokushisa kanye nomswakama wendawo ezungezile.
2. Izinkinga zokubopha
Ngokwehla kwezinga lokushisa kanye nomswakama kanye nokuwohloka kancane, kukhona nenkinga yokubopha phakathi kwe-structural sealant kanye ne-substrate. Izidingo ezijwayelekile zokusetshenziswa kwe-isivalo sesakhiwo se-siliconeimikhiqizo yile: indawo ehlanzekile enezinga lokushisa elingu-10°C kuya ku-40°C kanye nomswakama ohlobene ongu-40% kuya ku-80%. Uma kudlula izidingo zokushisa ezincane ezingenhla, ijubane lokubopha liyehliswa, futhi isikhathi sokubopha ngokugcwele ku-substrate siyandiswa. Ngesikhathi esifanayo, lapho izinga lokushisa liphansi kakhulu, ukumanzika kwe-glue kanye nobuso be-substrate kwehla, futhi kungase kube nenkungu noma iqhwa elingabonakali ebusweni be-substrate, okuthinta ukunamathelana phakathi kwe-structural sealant kanye ne-substrate.
Isixazululo: Uma izinga lokushisa eliphansi lokwakha le-structural sealant lingu-10 °C, i-structural sealant iboshelwa ku-substrate esimweni sangempela. Ukuhlolwa kokunamathela kufanele kwenziwe endaweni yokwakha enokushisa okuphansi ukuqinisekisa ukunamathela okuhle ngaphambi kokwakhiwa. Ukufakwa kwe-structural sealant efektri kungasheshisa nokuqina kwe-structural sealant ngokwandisa izinga lokushisa kanye nomswakama wendawo lapho kusetshenziswa khona i-structural sealant, futhi ngesikhathi esifanayo, kuyadingeka ukwandisa isikhathi sokuqina ngokufanele.
3. Khulisa ukujiya
Izinto zokuvala zesakhiwoizokhula kancane kancane futhi ibe uketshezi oluncane njengoba izinga lokushisa lehla. Kuma-sealant okwakha anezingxenye ezimbili, ama-sealant okwakha andisa i-viscosity azokwandisa ingcindezi yomshini wokunamathisela futhi anciphise ukuphuma kwe-sealant yokwakheka. Kuma-sealant okwakha anezingxenye eyodwa, i-sealant yokwakheka iyanda, ingcindezi eyengeziwe yesibhamu se-glue ukuze sikhiphe i-sealant yokwakheka ingaba isikhathi esiningi futhi ibe nzima ngemisebenzi yezandla.
Isixazululo: Uma kungekho mphumela ekusebenzeni kahle kokwakhiwa, ukuqina kwezinga lokushisa eliphansi kuyinto evamile, futhi azikho izinyathelo zokuthuthukisa ezidingekayo.
Uma ukwakhiwa kuthinta umphumela, kungenzeka ukucabangela ukwandisa izinga lokushisa lokusebenza kwe-structural sealant noma ukusebenzisa ezinye izindlela zokushisa ezisizayo, njengokugcina i-structural sealant egumbini lokushisa noma ekamelweni elinomoya opholile kusengaphambili, ukufaka i-heater yokushisa endaweni yokusebenzela yokunamathisela, nokwandisa
