Ingabe uyazi? Ebusika, i-sealant yesakhiwo nayo izofana neyomntwana, yenza intukuthelo encane, ngakho yiziphi izinkinga ezizobangela?
1.I-Structural sealant yelapheka kancane
Inkinga yokuqala ukwehla okungazelelwe kwezinga lokushisa okulethwa kuma-silicone sealant ukuthi azizwa ephuza ukuphulukiswa ngesikhathi sokufaka isicelo. Inqubo yokwelapha ye-structural silicone sealant iyinqubo yokusabela kwamakhemikhali, futhi izinga lokushisa kanye nomswakama wemvelo kunethonya elithile ejubaneni layo lokuphulukisa. Kuma-silicone sealant engxenye eyodwa yesakhiwo, izinga lokushisa liphezulu kanye nomswakama, isivinini sokuphulukisa sizoba ngokushesha. 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 kweglue endaweni encane ngaphambi kokusetshenziswa, futhi enze ukuhlolwa kokunamathela kwepeel ukuze kuqinisekiswe ukuthi i-sealant yesakhiwo ingelapheka, ukunamathela kuhle, futhi ukubukeka akuyona inkinga bese usebenzisa indawo enkulu. Kodwa-ke, lapho izinga lokushisa le-ambient lingaphansi kuka-4 ° C, ukwakhiwa kwe-structural sealant akunconywa. Uma imboni inezimo, ingacatshangelwa ngokukhuphula izinga lokushisa kanye nomswakama wendawo lapho kusetshenziswa khona i-sealant yesakhiwo.
2. Izinkinga ze-Structural sealant bonding
Ngokuncipha kwezinga lokushisa nomswakama, okuhambisana nokuphulukiswa kancane, kuphinde kube nenkinga yokubopha phakathi kwe-structural sealant ne-substrate. Izidingo ezijwayelekile zokusetshenziswa kwemikhiqizo ye-structural sealant yilezi: indawo ehlanzekile enezinga lokushisa elingu-10°C kuya ku-40°C kanye nomswakama ohlobene no-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: izinga lokushisa liphansi kunezinga lokushisa elincane lokwakhiwa kwesakhiwo se-sealant engu-10 ℃, isakhiwo sesakhiwo se-sealant sealant bonding material endaweni yokwakhiwa kwangempela kwezinga lokushisa eliphansi ukwenza ukuhlolwa kwebhondi, uqinisekise ukuhlangana okuhle, bese ukwakhiwa. Ifekthri ijove i-structural sealant, ngokwenza ngcono izinga lokushisa kanye nomswakama wendawo yokusetshenziswa kwe-sealant yesakhiwo ukusheshisa ukuphulukiswa kwe-structural sealant, kodwa futhi kudingeka futhi yelule isikhathi sokuphulukisa ngokufanelekile.
