01
I-Hot-Dip efakwe kwi-galvanized Unbonded Steel Strand
Intshayelelo yeMveliso
I-PC-strand, igalvanized-greased-PE-coated (ebizwa ngokuba yiHot-dip galvanized unbonded steel strand) lulwakhiwo olubalulekileyo kunye nezinto zobunjineli ezibonelela ngokusebenza okuqinileyo kunye nokuzinzileyo kwiintlobo ezahlukeneyo zezicelo. Inkqubo ye-galvanizing ye-hot-dip ibandakanya ukudipha imicu yentsimbi kwi-zinc etyhidiweyo ukubonelela ngengubo yokukhusela, ukudala i-coating ehlala ixesha elide kunye ne-corrosion-resistant ngaphakathi kunye nomphezulu we-pc strand.
Le misonto "ayinamabhondi," oku kuthetha ukuba ayibopheleli kwikhonkrithi ejikelezileyo, evumela ukuguquguquka okukhulu kunye nokuhamba. Ngenxa yokuqina kwayo okuphezulu kunye nokuxhathisa ukubola, olu hlobo lwe-strand luqhele ukusetyenziswa kwizicelo zokwakha ezifana ne-post-tensioning kunye ne-prestressed concrete structures.
Iimpawu zeMveliso
1)Ukusebenza kunye nezicelo zokunganyangeki kokuCorrosion:
I-Hot-dip galvanized coating inika ukhuseleko olugqwesileyo kwi-corrosion, yenza imisonto yentsimbi ifaneleke ngokukodwa usetyenziso kwiindawo ezilukhuni ezifana nokwakhiwa kweelwandle, iibhulorho kunye nezakhiwo zonxweme.
2) Amandla okuqina aphezulu:
Le misonto yentsimbi inamandla aphezulu, okwenza ukuba ibe yinto efanelekileyo kwi-prestressed kunye ne-post-tensioned concrete structures. Babonelela ngozinzo kwisakhiwo kunye nenkxaso kwiiprojekthi ezahlukeneyo zokwakha.
3)Ukuba bhetyebhetye:
Iintambo ezingabotshwanga zibonelela ngokuguquguquka okukhulu kunye nokuhamba ngaphakathi kwezakhiwo zekhonkrithi, ezizenza zilungele indawo yokulayisha eguquguqukayo, iindawo ze-seismic kunye nezicelo apho ukunyakaza kunye noxinzelelo kufuneka kuhanjiswe.
4) Ubomi obude:
I-galvanized coating yandisa ubomi benkonzo yeentsimbi zetsimbi, inceda ukunyusa ukuqina kunye nokuqina kwezakhiwo usebenzisa iintambo zetsimbi.
Izicelo zeMveliso
Iimveliso ezifunyenweyo zisetyenziswa ngokubanzi kulwakhiwo, ubunjineli boluntu kunye neeprojekthi zeziseko zophuhliso ngenxa yokunganyangeki kwazo, amandla aphezulu okuxinana kunye nokuguquguquka.
Izicelo: Imisonto yentsimbi engabotshwanga efakwe kwi-Hot-dip idla ngokusetyenziswa kuluhlu olubanzi lwezicelo ezibandakanya ukwakhiwa kwebhulorho, izakhiwo eziphakamileyo, izibophelelo zikaloliwe, izizinda zamandla enyukliya, kunye nezinye iiprojekthi zobunjineli boluntu kunye neziseko zophuhliso.
Izinto eziluncedo kwimveliso
1)Ukuqina:
Ingubo yokukhusela i-galvanized kwandisa kakhulu ubomi be-strand, ukunciphisa iindleko zokugcina kunye nokuphucula ukusebenza kwexesha elide.
2)UKhuseleko lokuMhlwa:
Iingubo ezenziwe ngegalvanized zisebenza njengesithintelo, ukukhusela intsimbi kumswakama, iikhemikhali, kunye nezinto ezisingqongileyo ezinokubangela ukubola kunye nokuthotywa.
3) Ukunciphisa umngcipheko wokwaphuka:
Amandla aphezulu aphezulu eentsimbi zetsimbi, adibaniswe nokuguquguquka okubonelelwa yi-designless bondless, ukunciphisa umngcipheko wokuphuka kunye nokuqinisekisa ukunyaniseka kwesakhiwo.
4) Ukuguquguquka:
Umsonto wentsimbi oshushu odiphu ongabotshwanga uyaguquguquka kwaye unokulungiswa ngokweemfuno ezithile zeprojekthi kwaye ufumaneka kwiidayamitha ezahlukeneyo, amandla okubamba kunye nokugqitywa komphezulu.
Ukuqukumbela, i-Hot-dip galvanized galvanized strand yentsimbi engabotshwanga idlala indima ebalulekileyo kumashishini okwakha kunye nobunjineli anika amandla, ukuqina kunye nokumelana nomhlwa. Ukusetyenziswa kwabo kwizakhiwo zekhonkrithi ezicinezelekileyo kunye nasemva koxinzelelo kunceda ukuphucula ukhuseleko, ixesha elide kunye nokusebenza kweeprojekthi zeziseko ezingundoqo. Ngokuguquguquka kwazo kunye nokugqitywa komgangatho ophezulu, le misonto iyaqhubeka ifuna uluhlu olubanzi lwezicelo zokwakha.
