Epoxy Coated PC Steel Strand
Intshayelelo yeMveliso
Ukusebenza kwe-mono-filament sprayed epoxy strand ihlangabezana neemfuno ze-GB / T25823-2010 "I-Mono-filament Coated Epoxy Coated Prestressed Steel Strand".
Ukusebenza kwe-epoxy steel strand ezaliswe ngokupheleleyo ihlangabezana neemfuno ze-GB / T21073-2007 "I-Epoxy Coated Seven Wire Prestressed Steel Strand" kunye ne-JT / T 737-2009 "I-Filled Epoxy Coated Steel Strand".
Ukusebenza kwegrisi ye-Anti-corrosion: Ngokuhambelana ne-JG 3007, yenziwe ngesepha ephezulu ye-lipid acid-proof carp ukuze ityebe i-oyile yeminerali esulungekisiweyo, yongeza i-antioxidants, i-anti-rust agents, i-anti-corrosion kunye nezinye izongezo, eziphucula i-oyile yeminerali ecocekileyo. ukuncamathela, ukumelana namanzi, ukuxhathisa umhlwa kunye nokuchasa ukubola kwegrisi echasayo.
Okwangoku, kukho imigangatho emibini yamazwe ngamazwe ye-epoxy coated steel strands, oko kukuthi, i-ASTM A 882 / A 882M-02a kunye ne-IS0 14655: 1999 (E). Kwimicu yensimbi ene-epoxy-coated, iintlobo ezimbini zeemveliso zichazwe: i-epoxy-coated strands kunye ne-epoxy-coated coated steel strands. Kwinguqu ye-ASTM ye-2002, kubalulekile ukucacisa i-epoxy-coated steel strands, kunye ne-epoxy-coated steel strands ayikhuthazwa; I-ISO 14655: 1999 (E) isekelwe kwi-ASTM A 882/A882M-96 kwaye ke igcina imimiselo yeemveliso ze-epoxy-coated strand, okt kuzo zombini iimveliso.
Ekubeni imisonto yentsimbi efakwe kwi-epoxy iyimveliso enokumelana nokugqwesa okugqwesileyo, kukho imimiselo engqongqo malunga nobukhulu bokugquma kunye neepinhole kumphezulu kuyo yomibini imigangatho. I-ASTM A 882/A 882M-02a ichaza ukutyeba kokutyabeka kwe-0.38 -1.14mm kwimisonto egcwele i-epoxy-coated. IS0 14655: 1999 (E) ichaza ukuba ubukhulu be-coating ye-epoxy coated fill steel strand yi-0.40-0.90mm; Ubukhulu be-coating ye-epoxy-coated strands yi-0.65 -1.15mm.
I-ASTM A882/A882M-02a kunye ne-IS0 14655:1999 (E) zombini zichaza ukuba akuyi kubakho zipinki kubude obupheleleyo be-epoxy-coated steel strand. Ngelo xesha, iimveliso zethu zihlangabezana neemfuno zombini imigangatho yamazwe ngamazwe ye-ASTM A882 / A882M-02a kunye ne-IS0 14655: 1999 (E) .
Iimpawu zeMveliso
Iintambo zentsimbi ezigqunywe yi-epoxy eziveliswe yinkampani yethu zineempawu ezibalaseleyo zokuchasa umhlwa,
I-1) Isithuba phakathi kweengcingo zetsimbi zetsimbi zetsimbi zizaliswe ngokupheleleyo yi-epoxy resin.
2) I-epoxy resin yokugqoka phezu komgangatho wentsimbi kunye nobukhulu obaneleyo, kwaye akukho nanye i-pinhole ubude bonke.
3) I-resin ekhethekileyo ye-epoxy ihlanganiswe ngokuqinileyo kunye ne-matrix yensimbi yentsimbi yentsimbi, eyandisa i-synchronously kwaye ingaqhekeki ngexesha nangemva koxinzelelo.
Izicelo zeMveliso
Njengohlobo olutsha lwezinto ezisebenza ngokuphezulu ezichasene nomhlwa, i-epoxy coated steel strand isetyenziswa ngokubanzi kwiindawo ezininzi zobunjineli ezifana neentambo ezihlala intambo, iintambo ezihlala kwi-cable, iintambo zangaphandle (kubandakanywa neentambo zokubopha), iintambo zangaphakathi, i-geotechnical. i-anchorage, njl., e-United States, eYurophu, eJapan, e-Australia nakwamanye amazwe aseYurophu, eMelika kunye ne-Asia-Pacific kunye nemimandla.
Inkampani yethu ineentambo ezili-16 ezihlala intambo eKorla Landscape Bridge ziintambo zeankile ezikhutshiweyo ezenziwe ngobuchwephesha be-extrusion. Imveliso entsha ye-17.8mm epoxy egqunywe ngumsonto wentsimbi eveliswe yinkampani yethu iye yasetyenziswa kwiprojekthi yesakhiwo sentsimbi yeshedi yamalahle eDalian Xizhong Island Heating Project, ekwayiprojekthi yokuqala eTshayina ukusebenzisa i-17.8mm epoxy coated prestressed steel strand. . (I-Deflection tensile factor:
