Uyazi? Ebusika, i-structural sealant nayo izofana neyengane, yenze umsindo omncane, ngakho-ke yiziphi izinkinga ezizobangelwa yiyo?
1. I-sealant yesakhiwo iyelapha kancane
Inkinga yokuqala ukwehla okungazelelwe kwezinga lokushisa elizungezile kulethwa yizicucu ze-silicone sealant ukuthi zizizwa ziphuza ukuphola ngesikhathi sokusetshenziswa. Inqubo yokuphola ye-silicone sealant yesakhiwo iyinqubo yokusabela kwamakhemikhali, futhi izinga lokushisa kanye nomswakama wendawo kunomthelela othile esivinini sayo sokuphola. Kuma-silicone sealant esakhiwo anengxenye eyodwa, izinga lokushisa kanye nomswakama liphakeme, isivinini sokuphola sizoshesha kakhulu. Ngemva kobusika, izinga lokushisa lehla kakhulu, futhi ngesikhathi esifanayo, ngomswakama ophansi, ukusabela kokuphola kwe-sealant yesakhiwo kuyathinteka, ngakho-ke ukuphola kwe-sealant yesakhiwo kuhamba kancane. Ngaphansi kwezimo ezivamile, lapho izinga lokushisa liphansi kune-15 ℃, isimo sokuphola kancane kwe-sealant yesakhiwo sisobala kakhulu.
Isixazululo: Uma umsebenzisi efuna ukwakha endaweni enezinga lokushisa eliphansi, kunconywa ukuthi enze ukuhlolwa kweglue endaweni encane ngaphambi kokusebenzisa, futhi enze ukuhlolwa kokunamathela kwe-peel ukuqinisekisa ukuthi i-structural sealant ingalapheka, ukunamathela kuhle, futhi ukubukeka kwayo akunankinga bese esebenzisa indawo enkulu. Kodwa-ke, uma izinga lokushisa elizungezile liphansi kune-4°C, ukwakhiwa kwe-structural sealant akukhuthazwa. Uma ifektri inezimo, kungacatshangelwa ngokwandisa izinga lokushisa kanye nomswakama wendawo lapho kusetshenziswa khona i-structural sealant.
2. Izinkinga zokubopha i-sealant yesakhiwo
Ngokwehla kwezinga lokushisa kanye nomswakama, okuhambisana nokuqiniswa kancane, kukhona nenkinga yokubopha phakathi kwe-structural sealant kanye ne-substrate. Izidingo ezijwayelekile zokusebenzisa imikhiqizo ye-structural sealant yilezi: 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 kwi-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: izinga lokushisa liphansi kunezinga lokushisa elincane lokwakha le-sealant yesakhiwo esingu-10℃, isisekelo se-sealant yesakhiwo se-bonding material endaweni yokushisa ephansi yangempela yokwakha ukwenza isivivinyo sokubopha, ukuqinisekisa ukubopha okuhle, bese kwakhiwa. Ifektri ifake i-sealant yesakhiwo, ngokuthuthukisa izinga lokushisa kanye nomswakama wendawo yokusetshenziswa kwe-sealant yesakhiwo ukuze kusheshiswe ukuqina kwe-sealant yesakhiwo, kodwa futhi kudingeka yandise isikhathi sokuqina ngokufanele.
