I-Epoxy Coated PC Steel Strand
Isingeniso Somkhiqizo
Ukusebenza kwe-mono-filament sprayed epoxy steel strand kuhlangabezana nezidingo ze-GB/T25823-2010 "Mono-filament Coated Epoxy Coated Prestressed Steel Strand".
Ukusebenza kwe-epoxy steel strand egcwele ihlangabezana nezidingo ze-GB/T21073-2007 "I-Epoxy Coated Seven Wire Prestressed Steel Strand" kanye ne-JT/T 737-2009 "Filled Epoxy Coated Steel Strand".
Ukusebenza kwamafutha e-anti-corrosion: Ngokuhambisana ne-JG 3007, yenziwe ngensipho ye-carp yezinga eliphezulu ye-lipid acid ukuze ijiye uwoyela wamaminerali acwengisiswe ngokujulile, engeze ama-antioxidants, ama-anti-rust agents, anti-corrosion nezinye izithasiselo, okuthuthukisa ukubola. ukunamathela, ukumelana namanzi, ukumelana nokugqwala kanye ne-anti-corrosion ye-anti-corrosion grease.
Njengamanje, kunezindinganiso ezimbili zamazwe ngamazwe zemicu yensimbi ene-epoxy coated, okuyi-ASTM A 882/A 882M-02a kanye ne-IS0 14655:1999 (E). Ngemicu yensimbi ene-epoxy-coated, izinhlobo ezimbili zemikhiqizo zicacisiwe: imicu egcwele i-epoxy-coated kanye nemicu yensimbi ehlanganiswe nge-epoxy. Kunguqulo ka-2002 yezinga le-ASTM, kubalulekile ukucacisa izintambo zensimbi ezigcwele i-epoxy-coated, futhi izintambo zensimbi ezifakwe epoxy azinconywa; I-ISO 14655:1999 (E) isekelwe ku-ASTM A 882/A882M-96 futhi ngenxa yalokho igcina imithetho yemikhiqizo ye-epoxy-coated strand, okungukuthi kuyo yomibili imikhiqizo.
Njengoba imicu yensimbi ene-epoxy-coated ingumkhiqizo onokumelana nokugqwala okuhle kakhulu, kunemithetho eqinile mayelana nokujiya kokumboza namaphinifa angaphezulu kuwo womabili la mazinga. I-ASTM A 882/A 882M-02a icacisa ukujiya kokumboza okungu-0.38 -1.14mm emicu egcwele e-epoxy. I-IS0 14655:1999 (E) ibeka ukuthi ukujiya kokumboza komucu wensimbi ogcwele i-epoxy ku-0.40-0.90mm; Ugqinsi lokwemboza lwezintambo ezimbozwe nge-epoxy ngu-0.65 -1.15mm.
I-ASTM A882/A882M-02a kanye ne-IS0 14655:1999 (E) zombili zicacisa ukuthi akumele kube namaphinifa ubude obugcwele bomucu wensimbi osuqediwe we-epoxy-coated. Ngesikhathi esifanayo, imikhiqizo yethu ihlangabezana nezidingo zazo zombili izindinganiso zamazwe ngamazwe ze-ASTM A882/A882M-02a kanye ne-IS0 14655:1999 (E) .
Izici Zomkhiqizo
Izintambo zensimbi ezihlanganiswe yi-epoxy ezikhiqizwe yinkampani yethu zinezakhiwo ezinhle kakhulu zokulwa nokugqwala,
1) Igebe phakathi kwezintambo zensimbi zomucu wensimbi ligcwaliswa ngokuphelele nge-epoxy resin.
2) I-epoxy resin embozwe ngaphezulu komucu wensimbi enogqinsi olwanele, futhi akukho mbobo yokukhonkwane kubo bonke ubude.
3) I-epoxy resin ekhethekile iboshwe ngokuqinile ne-matrix yensimbi ye-strand yensimbi, enwebeka ngokuhambisanayo futhi ingaqhekeki ngesikhathi nangemuva kokuqina.
Izicelo Zomkhiqizo
Njengohlobo olusha lwezinto ezisebenza kahle ezimelene nokugqwala, intambo yensimbi ene-epoxy coated isetshenziswa kabanzi emikhakheni eminingi yobunjiniyela njengezintambo ezihlala ikhebula, izintambo ezihlala ingxenye yamakhebula, izintambo zangaphandle (kuhlanganise nezintambo zokubopha), izintambo zangaphakathi, i-geotechnical. i-anchorage, njll., e-United States, eYurophu, eJapane, e-Australia nakwamanye amazwe aseYurophu, eMelika nase-Asia-Pacific nasezifundeni.
Izintambo zenkampani yethu eziyi-16 ezihlala ikhebula e-Korla Landscape Bridge ziyizintambo ezifakwa ngaphansi kwe-extrusion ezenziwe ngobuchwepheshe be-extrusion. Umkhiqizo omusha ongu-17.8mm epoxy coated prestressed strand okhiqizwe yinkampani yethu ususetshenziswe kuphrojekthi yensimbi yeshede lamalahle elomile leDalian Xizhong Island Heating Project, okuphinde kube iphrojekthi yokuqala eChina ukusebenzisa umucu wensimbi ongu-17.8mm epoxy coated prestressed prestressed. .
