Epoxy Yashizwemo PC Icyuma
Kumenyekanisha ibicuruzwa
Imikorere ya mono-filament yatewe icyuma cya epoxy cyujuje ibyangombwa bya GB / T25823-2010 "Mono-filament Coated Epoxy Coated Prestressed Steel Strand".
Imikorere yicyuma cyuzuye epoxy yujuje ibyangombwa bisabwa na GB / T21073-2007 "Epoxy Coated Seven Wire Prestressed Steel Strand" na JT / T 737-2009 "Yuzuye Epoxy Coated Steel Strand".
Imikorere yo kurwanya amavuta ya ruswa: Mu buryo buhuye na JG 3007, ikozwe mu isabune yo mu rwego rwohejuru ya lipide aside irwanya karp kugira ngo yongere amavuta y’amabuye meza yatunganijwe neza, yongereho antioxydants, imiti irwanya ingese, irwanya ruswa n’ibindi byongerera imbaraga, bitezimbere gufatira, kurwanya amazi, kurwanya ingese no kurwanya ruswa y'amavuta yo kurwanya ruswa.
Kugeza ubu, hari amahame abiri mpuzamahanga ya epoxy yometseho ibyuma, aribyo ASTM A 882 / A 882M-02a na IS0 14655: 1999 (E). Kuri epoxy-yometseho ibyuma, ubwoko bubiri bwibicuruzwa birasobanuwe: epoxy-yuzuyeho imirongo yuzuye hamwe na epoxy-yometseho ibyuma. Muri verisiyo ya 2002 yuburyo bwa ASTM, ni ngombwa kwerekana epoxy-yometseho ibyuma byuzuye, kandi epoxy-yometseho ibyuma ntibisabwa; ISO 14655: 1999 (E) ishingiye kuri ASTM A 882 / A882M-96 bityo ikagumana amabwiriza agenga ibicuruzwa biva mu bwoko bwa epoxy, ni ukuvuga kubicuruzwa byombi.
Kubera ko ibyuma bya epoxy bifatanyirijwe hamwe nibicuruzwa bifite imbaraga zo kurwanya ruswa, hariho amategeko akomeye yerekeranye no gutwikira umubyimba na pinhole hejuru yuburinganire bwombi. ASTM A 882 / A 882M-02a yerekana uburebure bwa 0.38 -1.14mm kuri epoxy-yuzuye imirongo yuzuye. IS0 14655: 1999 (E) iteganya ko umubyimba wububiko bwa epoxy utwikiriye umugozi wuzuye ni 0.40-0.90mm; Umubyimba wububiko bwa epoxy-utwikiriye imirongo ni 0,65 -1.15mm.
ASTM A882 / A882M-02a na IS0 14655: 1999 (E) byombi byerekana ko ntihazabaho pinhole mu burebure bwuzuye bw'icyuma cyarangijwe na epoxy. Muri icyo gihe, ibicuruzwa byacu byujuje ibisabwa byombi ku rwego mpuzamahanga mpuzamahanga rwa ASTM A882 / A882M-02a na IS0 14655: 1999 (E).
Ibiranga ibicuruzwa
Epoxy yatwikiriye ibyuma byakozwe na societe yacu ifite ibintu byiza birwanya ruswa,
1) Ikinyuranyo hagati yinsinga zicyuma cyumurongo wicyuma cyuzuyemo epoxy resin.
2) Epoxy resin itwikiriye hejuru yumurongo wibyuma hamwe nubunini buhagije, kandi ntanumwe pinhole muburebure bwose.
3) Epoxy resin idasanzwe ihujwe neza na matrike yicyuma yumurongo wibyuma, irambuye icyarimwe kandi idacika mugihe na nyuma yo guhagarika umutima.
Ibicuruzwa
Nubwoko bushya bwibikorwa byinshi byo kurwanya ruswa byamamaye, umugozi wa epoxy utwikiriye ibyuma bikoreshwa cyane mubice byinshi byubwubatsi nka insinga zagumyeho insinga, insinga zagumye igice, insinga zo hanze (harimo insinga za karuvati), insinga zimbere, geotechnical inanga, nibindi, muri Amerika, Uburayi, Ubuyapani, Ositaraliya nibindi bihugu byuburayi, Amerika na Aziya-Pasifika.
Isosiyete yacu ya kabili 16 yagumye muri kabili muri Korla Landscape Bridge ni insinga zo gukuramo ibyuma byakozwe na tekinoroji yo gukuramo. Ibicuruzwa bishya 17.8mm epoxy yometseho icyuma cyamamaye cyakozwe nisosiyete yacu cyashyizwe mubikorwa umushinga wibyuma byumushinga wamakara yumye ya Dalian Xizhong Island Heating Project, akaba ariwo mushinga wambere mubushinwa wakoresheje 17.8mm epoxy yubatswe nicyuma cyicyubahiro .
