O le faʻatinoga o le faʻatumuina o le epoxy uamea e fetaui ma manaʻoga o le GB / T21073-2007 "Epoxy Coated Seven Wire Prestressed Steel Strand" ma le JT / T 737-2009 "Flled Epoxy Coated Steel Strand".
Anti-corrosion ga'o faatinoga: E tusa ai ma le JG 3007, e faia i le maualuga-grade lipid acid-fasimoli carp fasimoli e mafiafia loloto suauʻu minerale faamamaina, faaopoopo antioxidants, anti-ele agents, anti-corrosion ma isi additives, lea e faaleleia ai le pipii, vai tetee, ele tetee ma anti-corrosion o le anti-corrosion gaʻo.
I le taimi nei, e lua tulaga fa'ava-o-malo mo manoa u'amea ua ufiufi epoxy, e ta'ua ASTM A 882/A 882M-02a ma IS0 14655:1999 (E). Mo manoa u'amea epoxy, e lua ituaiga o oloa o lo'o fa'amaoti mai: epoxy-coated fa'atumu manoa ma epoxy-coated fa'alava uamea manoa. I le 2002 version of the ASTM standard, e taua tele le faʻamaonia o manoa uʻamea faʻatumu epoxy, ma e le fautuaina ni manoa uʻamea epoxy; ISO 14655: 1999 (E) e fa'avae i le ASTM A 882/A882M-96 ma o lea e tumau ai tulafono mo oloa fa'apipi'i epoxy, ie mo oloa uma e lua.
Talu ai o laina uʻamea faʻapipiʻiina epoxy o le oloa ia e sili ona lelei le faʻafefeteina, o loʻo i ai tulafono faʻatonutonu i luga o le mafiafia o le ufiufi ma pine i luga o luga i tulaga uma e lua. ASTM A 882/A 882M-02a o loʻo faʻamaonia ai le mafiafia o le ufiufi o le 0.38 -1.14mm mo manoa faʻatumu epoxy-coated. IS0 14655:1999 (E) o loʻo faʻamaonia ai o le mafiafia o le ufiufi o le epoxy faʻapipiʻiina uamea faʻatumu e 0.40-0.90mm; O le mafiafia faʻapipiʻi o manoa epoxy-coated e 0.65 -1.15mm.
ASTM A882/A882M-02a ma le IS0 14655:1999 (E) o loʻo faʻamaoti uma e le tatau ona i ai ni pu i le umi atoa o le manoa uamea ua ufiufi epoxy. I le taimi lava e tasi, oa tatou oloa e fetaui ma manaʻoga mo tulaga faʻavaomalo e lua o le ASTM A882/A882M-02a ma le IS0 14655:1999 (E).
Oloa Fa'ailoga
O manoa u'amea fa'apipi'i epoxy na gaosia e la matou kamupani e iai mea e sili ona lelei e tete'e ai,
1) O le va i le va o uaea uʻamea o le uʻamea uamea ua faʻatumu atoatoa e le epoxy resin.
2) O le epoxy resin faʻapipiʻi i luga o le pito o le sila ua lava le mafiafia, ma e leai se pine i le umi atoa.
3) O le resin epoxy faʻapitoa e faʻapipiʻi mau ma le matrix uʻamea o le uʻamea uʻamea, lea e faʻalautele faʻatasi ma e le taʻe i le taimi ma pe a uma le faʻalavelave.
