AWWA C213 umuyoboro wamazi wibyumani igifuniko cya FBE gikoreshwa imbere ninyuma yimbere yumuyoboro wibyuma kugirango ukoreshwe muri sisitemu yo kuvoma amazi yo munsi cyangwa munsi y'amazi.
Ipfunyika ritanga uburinzi bwo kwangirika kandi ritanga imikorere yizewe ya sisitemu y'umuyoboro mugihe kinini mugihe cyo munsi yubutaka cyangwa amazi.
Umuyoboro w'inyuma wa diameter ≥ 660mm [24in] .Epoxy resin umurongo hamwe no kugera kumuyoboro wo kugenzura no kubungabunga.
Imirambararo yicyuma <660mm [24in] nayo irashobora kuba nziza, mugihe hari uburyo bukwiye bwo kugenzura ubusugire bwimbere.
Fusion Bonded Epoxy (FBE)ni igice kimwe cyumye cyifu ya thermosetting epoxy resin iyo, iyo ikozwe nubushyuhe, itera reaction yimiti hejuru yumuyoboro wibyuma mugihe ikomeza imiterere yayo.
Ifu ya epoxy igomba kuba igizwe nigice kimwe cyo guhuza ibintu bigizwe na epoxy resin, imiti ikiza, catalizator, yuzuza, ibara, imiti igenzura, hamwe na UV inhibitor.
Ibikoresho bigomba kubahiriza ibisabwa naAmategeko yo kunywa meza.
Iyo bisabwa kubahiriza NSF, ibikoresho bihuye n’amazi meza bigomba kwemezwa kuri NSF / ANSI / CAN Standard 61.
Muri rusange, ubushyuhe ntarengwa bwo gukoresha ubushyuhe ni hafi65 ° C (150 ° F).Byongeye kandi, ubuzima bwa serivisi yo gutwikira buragabanuka mugukomeza ubushyuhe bwo hejuru mugihe kirekire.
Iyo ushyizwe mubintu bishyushye ukoresheje spray ya electrostatike, uburiri bwuzuye amazi cyangwa gutera ikirere hanyuma bigakira, ifu ya epoxy itanga igipfundikizo kimwe cyo gukingira.
Ibikorwa byihariye nibi bikurikira:
Kugenzura imiyoboro no kubanza kuvura
Ubuso buzaba butarimo inenge zigira ingaruka ku bicuruzwa byanyuma, nka burrs, gouges, hamwe na spatter weld, zishobora kuvanwaho n'umucanga.
kandi hejuru yubutaka hazaba hatarimo ibyondo, irangi ryurusyo, ibishashara, igitara cyamakara, asfalt, amavuta, amavuta, chloride, nibindi bintu byose byamahanga cyangwa ibyuka bishobora gutwikwa bishobora gutwikwa nubushyuhe bwa epoxy.Kuraho ibiboneka byamavuta hamwe namavuta uhanagura umusemburo udasigara.
Gutegura Ubuso
Koresha umusenyi wumye kugirango usukure ingese hejuru yicyuma.
Ibidukikije bisabwa Ibisabwa: Iyo ubushyuhe bwumuyoboro wibyuma ari 3 ° C (5 ℉) hejuru yubushyuhe bwikime.
Isuku yo hejuru: Ubuso bwumuyoboro wicyuma wamanutse ugomba kuba ukurikije SSPC-SP10 / NACE No 2.
Ubuso bwubuso: Uburebure bwimbuto za Anchor zingana na 51-102 mm (2.0-4.0 mil) zapimwe hakurikijwe ASTM D4417.Ibi birashobora gupimwa hamwe na ankeri yerekana hejuru cyangwa metero ya metero.
Ubuso bwubuso bwimbitse cyane cyangwa buto cyane bizagira ingaruka kumikorere ya nyuma ya FBE.
Icyitonderwa: Nyamuneka andika igihe kiri hagati yo kurangiza kumanuka no gutwikira kugirango wirinde ingese.
Isuku yo mu kirere
Umwuka uhumanye udahumanye ugomba gukoreshwa kugirango uhindure umukungugu, grit, cyangwa ibindi bintu by’amahanga bivuye munsi yubutaka bwateguwe bwumuyoboro muburyo butagira ingaruka kubutaka bwasukuwe, indi miyoboro isukuye, cyangwa umuyoboro ugomba gutwikirwa cyangwa gutondekwa.
Gushyushya imiyoboro
Shyushya umuyoboro wicyuma ukoresheje isoko yubushyuhe butagomba kwanduza hejuru yumuyoboro, ariko ntigomba kurenga 274 ° C (525 ° F).
Ubushyuhe bwo hejuru bushobora guhindura imiterere yumubiri hamwe nuburemere bwibyuma.
Ubushyuhe bwubuso bwumuyoboro wibyuma burashobora gupimwa ukoresheje ikaramu ya termometero cyangwa kalibibasi ya optique ya termometero.
Niba ibara ry'ubururu ribaye, umuyoboro ugomba gukonjeshwa ubushyuhe bwibidukikije hanyuma ukongera guturika.
Uburyo bwo gutwikira
Ifu ya FBE ikoreshwa muburyo bumwe hejuru yicyuma gishyushye mugushonga uburiri, gutera electrostatike, cyangwa gutera umwuka.
Grooves, beveled, cyangwa imizi hejuru ntigomba kuba FBE.
Iyo hakoreshejwe reberi ya gaze cyangwa imashini ikoreshwa, epoxy igomba kugera kumpera yumuyoboro keretse iyo byagenwe ukundi nuwaguze.
Gukonja
Gukonja birashobora gukorwa n'umwuka cyangwa amazi.
PQT: Kugura AWWA C213 Umuyoboro wohereza amazi Umuyoboro muke mbere yo kugura byinshi.Ibipimo cyangwa ibizamini bikorwa kugirango hamenyekane ko ibicuruzwa cyangwa sisitemu byujuje ubuziranenge n'ibipimo ngenderwaho.
Ibi birimo ibizamini bya laboratoire, gusuzuma imikorere, nibindi bikorwa.
Ibigaragara
Epoxy igomba kuba yoroshye muri rusange.
Epoxy ntigomba kugira ibisebe, ibice, ibibyimba, gusiba, cyangwa izindi nenge zigaragara.
Ubusembwa bwo kwisiga, nka sags, gucogora, guswera, gutwikira, hejuru ya spray, na / cyangwa orange-peel, ntibishobora gufatwa nkimpamvu yo kwangwa cyangwa gusanwa.
Igenzura ry'amashanyarazi kugirango rikomeze (ikizamini cya voltage nto)
Gukomeza gutwikirwa bigomba kugenzurwa hakurikijwe NACE SPO490.
Kumurongohamwe n'ubugari bwa mil 20 (508 um) cyangwa munsi yayo, icyuma gipima ibiruhuko gike gishyizwe hejuru ya 75 V kizakoreshwa hakurikijwe NACE SPO188.
Niba umubare w'ikiruhuko urenze umubare uri munsi ya coating uzakenera gukurwaho no kongera gukorwa.
Hanze ya diameter (OD) <14in (360 mm), ibiruhuko 1 / metero (3 ft).
Hanze ya diameter (OD) ≥ 14in (360 mm), ibiruhuko 1/25 ft² (2,3 mm²).
Fata iminsi mikuru yagenzuwe, uyisane, kandi wongere ugerageze.
Kwizirika
Gufatanya na epoxy yakize hejuru yumuyoboro birashobora kugerwaho mugusunika icyuma gityaye muri epoxy hejuru yumuyoboro no gukoresha umuhoro wo guhinga kugirango ugerageze gukuraho epoxy hejuru yumuyoboro.
Epoxy igomba kwizirika rwose kumuyoboro uri kumuyoboro irwanya byimazeyo ibikorwa byo guhinga kandi ntizigire imyanda yamenetse kandi ihure naigipimo cya adhesion ya 1-3.
Umubyimba
Umubyimba wa firime yakize ntigomba kuba munsi ya 305um (12mil), harimo nogusudira.
Muri verisiyo ishaje ya AWWA C213, hari imbibi zingana na 406 um (16 mils) umubyimba ntarengwa, wavanyweho muri verisiyo iheruka kubera ingorane zo kugera kubisabwa mugihe cyibisekuruza nyirizina.
Ibizamini by'inyongera
Ibizamini byinyongera birashobora gutomorwa kugirango umenye imikorere ya epoxy.
1. Kwambukiranya ibice.
2. Imigaragarire yimbere.
3. Isesengura ry'ubushyuhe (DSC).
4. Guhangayikishwa burundu (kugoreka).
5. Shira amazi.
6. Ingaruka.
7. Ikizamini cya cathodic disbondment.
Igomba gushyirwaho neza nizina ryuwabikoze, ubwoko bwibikoresho, icyiciro cyangwa nimero myinshi, itariki yakozwe, nuburyo bwo kubika.
Ahanini kumiyoboro itanga amazi
Ububiko bwo hanze busanzwe bukoreshwa mukurinda imiyoboro kwangirika kw ibidukikije, mugihe impuzu zimbere zikoreshwa mukurinda kwanduza amazi, kugabanya ubukana bwo guterana amagambo, no kongera ubuzima bwimiyoboro.Iyi myenda ifasha kwemeza kwizerwa no kuramba kwa sisitemu yo kuvoma, kubahiriza ibipimo by’isuku, no kugabanya ibikenewe kubungabungwa.
