Umuyoboro w'amazi w'icyuma wa AWWA C213ni igitambaro cya FBE gishyirwa imbere n'inyuma by'imiyoboro y'icyuma gikoreshwa mu miyoboro y'amazi yo munsi y'ubutaka cyangwa munsi y'amazi.
Iyi paki itanga uburinzi ku ingese kandi igatuma sisitemu y'imiyoboro ikora neza igihe kirekire mu butaka cyangwa mu mazi.
Umurambararo w'inyuma w'umuyoboro ≥ 660mm [inchi 24]. Umwambaro wa epoxy resin ufite inzira yo kugera ku muyoboro kugira ngo ugenzurwe kandi ukomeze kubungabungwa.
Umurambararo w'imiyoboro y'icyuma <660mm [inchi 24] nawo ushobora kuba ukwiriye, mu gihe hari uburyo bukwiye bwo kugenzura ubuziranenge bw'igitambaro cy'imbere.
Epoxy y'imigozi ivanze (FBE)ni resini ya epoxy ikoreshwa mu gushyushya ifu yumye, iyo ikoreshejwe n'ubushyuhe, ikora imikorere y'ibinyabutabire ku buso bw'umuyoboro w'icyuma mu gihe ikomeza kugira imiterere yayo.
Ifu ya epoxy igomba kuba igizwe n'ikintu kimwe gifatanye kigizwe na resin ya epoxy, umuti uvura, katalyst, filler, colorant, agent control flow, na UV inhibitor.
Ibikoresho bigomba kubahiriza ibisabwa n'amategeko agengaItegeko ry'amazi meza yo kunywa.
Iyo bikenewe kubahiriza amategeko ya NSF, ibikoresho bihuye n'amazi meza bigomba kwemezwa hakurikijwe amahame ya NSF/ANSI/CAN 61.
Muri rusange, ubushyuhe ntarengwa bwo gukoresha ku gusiga ni hafiUbushyuhe bwa 150°F (65°C)Byongeye kandi, igihe cyo gukora cy'igitambaro kiragabanuka iyo ubushyuhe bwinshi bugumanye igihe kirekire.
Iyo ikoreshejwe ku bintu byashyushye hakoreshejwe amashanyarazi, ikoreshwa mu gutera amazi cyangwa umwuka hanyuma igakira, ifu ya epoxy ikora irangi ririnda rimwe.
Ibikorwa byihariye ni ibi bikurikira:
Isuzuma ry'imiyoboro no kuyitunganya mbere yo kuyitunganya
Ubuso bugomba kuba budafite inenge zigira ingaruka ku bicuruzwa bya nyuma, nka burrs, gouges, na weld spatters, zishobora gukurwaho hakoreshejwe sanding.
kandi ubuso bugomba kuba budafite icyondo, irangi ry’inganda, ishashi, kaburimbo y’amakara, asphalt, amavuta, amavuta, kloride, n’ibindi bintu byose by’imvange cyangwa ibintu bishobora gushya bishobora gushya mu gihe cy’ubushyuhe bwa epoxy ikoreshejwe. Kuraho utudomo tugaragara tw’amavuta n’amavuta uhanagura ukoresheje umuti ugabanya ubushyuhe udasiga ibisigazwa.
Gutegura ubuso
Koresha umucanga wumye kugira ngo ukureho ingese zo hejuru ku muyoboro w'icyuma.
Ibisabwa ku bidukikije byo guturika: Iyo ubushyuhe bw'umuyoboro w'icyuma buri hejuru ya 3°C (5℉) hejuru y'ubushyuhe bw'ikigero cy'umuvuduko w'amazi.
Isuku y'ubuso: Ubuso bw'umuyoboro w'icyuma wakuweho bugomba kuba bukurikije SSPC-SP10/NACE No. 2.
Uburemere bw'ubuso: Ubujyakuzimu bw'ibinyampeke by'inkingo buri hagati ya 51-102 μm (2.0-4.0 mil) bupimwe hakurikijwe ASTM D4417. Ibi bishobora gupimwa hakoreshejwe icyuma gipima imiterere y'inkingo cyangwa icyuma gipima imiterere y'inkingo.
Ubuso bukabije cyane cyangwa buto cyane buzagira ingaruka ku mikorere y'igitambaro cya nyuma cya FBE.
Icyitonderwa: Nyamuneka menya igihe kiri hagati yo kurangiza gukuraho ubushyuhe n'igihe cyo gusiga kugira ngo hirindwe ingese.
Gusukura umwuka
Umwanya ufunze udafite umwanda ugomba gukoreshwa mu guhuha ivumbi, ibicanga, cyangwa ibindi bintu biva mu gice cy’umuyoboro cyateguwe mu buryo butagize ingaruka ku buso busukuwe, ku yindi miyoboro isukuye, cyangwa ku muyoboro ugomba gupfukwa cyangwa gushyirwaho.
Gushyushya imiyoboro
Shyushya umuyoboro w'icyuma ukoresheje isoko y'ubushyuhe idakwiye kwanduza ubuso bw'umuyoboro, ariko ntigomba kurenza 274°C (525°F).
Ubushyuhe bwinshi bushobora guhindura imiterere y'icyuma n'imiterere yacyo.
Ubushyuhe bw'ubuso bw'umuyoboro w'icyuma bushobora gupimwa hakoreshejwe ikaramu ya thermometer cyangwa thermometer y'urumuri ifite ubushobozi bwo gupima.
Iyo habayeho ibara ry'ubururu, umuyoboro ugomba gukonjeshwa kugeza ku bushyuhe bw'ikirere hanyuma ukongera guturitswa.
Uburyo bwo gusiga
Ifu ya FBE ishyirwa ku buso bw'umuyoboro w'icyuma ushyushye mu buryo bumwe binyuze mu gushonga, gutera amashanyarazi, cyangwa gutera umwuka.
Imirongo, imigozi, cyangwa impande z'imizi ntigomba gutwikirwa na FBE.
Iyo hakoreshejwe imigozi cyangwa imigozi ikoreshwa mu byuma, epoxy igomba kugera ku mpera z'umuyoboro keretse iyo umuguzi yabigennye ukundi.
Gukonjesha
Gukonjesha bishobora gukorwa hakoreshejwe umwuka cyangwa amazi.
PQT: Gura umuyoboro w'icyuma gikwirakwiza amazi wa AWWA C213 mu rugero ruto rw'igerageza mbere yo kugura ingano nyinshi. Hakorwa isuzuma mbere y'uko ibicuruzwa cyangwa sisitemu byuzuza ibisabwa byihariye by'ubuziranenge n'imikorere.
Ibi birimo ibizamini bya laboratwari, isuzuma ry'imikorere, n'izindi nzira.
Isura
Epoxy igomba kuba yoroshye muri rusange.
Epoxy ntigomba kugira udusebe, imiturire, uduheri, ivangura, cyangwa izindi nenge zigaragara.
Ubusembwa bwo kwisiga, nko gucikagurika, gushwanyagurika, gupfuka, gusukura hejuru y’isuka, cyangwa igishishwa cy’umuhondo, ntibigomba gufatwa nk’impamvu yo kwangwa cyangwa gusanwa.
Igenzura ry'amashanyarazi kugira ngo harebwe uburyo rikomeza (ikizamini cy'iminsi mikuru cy'amashanyarazi make)
Gukomeza gutwikira bigomba kugenzurwa hakurikijwe NACE SPO490.
Ku bijyanye n'imitakoifite ubugari bwa mililitiro 20 (508 um) cyangwa munsi yayo, hagomba gukoreshwa agakoresho gapima umuriro gafite ingufu nkeya gafite ubugari bwa dogere 75 V hakurikijwe NACE SPO188.
Iyo umubare w'iminsi mikuru urenze umubare uri munsi y'igitambaro kizakenera gukurwaho no kongera gukorwa.
Umurambararo wo hanze (OD) <14in (360 mm), 1 holiday/meter (3 ft).
Umurambararo wo hanze (OD) ≥ santimetero 360 (360 mm), ikiruhuko 1/futi 25 (2.3 mm²).
Fata iminsi mikuru yagenzuwe, uyisane, hanyuma wongere uyipime.
Gufata ku ruhande
Gufata epoxy yavunitse ku buso bw'umuyoboro bishobora kugerwaho binyuze mu gusunika icyuma gityaye unyuze muri epoxy ku buso bw'umuyoboro no gukoresha uburyo bwo gucukura mu rwego rwo gukura epoxy ku buso bw'umuyoboro.
Epoxy igomba gufatanywa neza n'umuyoboro uri ku muyoboro, ikarwanya cyane ubuhinzi kandi idafite imyanda icikagurika kandi igahura n'umuyoboro.amanota yo gufatana (adhesion) ya 1-3.
Ubunini
Ubunini bw'agapira gasukuye ntibugomba kuba munsi ya 305um (12mil), harimo n'imigozi yo gusudira.
Muri verisiyo ishaje ya AWWA C213, hari umupaka ntarengwa wa 406 um (16 mils) w'ubugari ntarengwa bwo gutwikira, wakuweho muri verisiyo iheruka kubera ingorane zo kugera kuri iki gisabwa mu gihe cyo gukora nyacyo.
Ibizamini by'inyongera
Ibizamini by'inyongera bishobora kugaragazwa kugira ngo hamenyekane imikorere ya epoxy.
1. Ubushobozi bwo gupfundika ibice.
2. Uburyo bwo gupima aho umurongo uherereye.
3. Isesengura ry'ubushyuhe (DSC).
4. Gukomereka burundu (guhindagurika).
5. Kuroba mu mazi.
6. Ingaruka.
7. Ikizamini cyo gusenyuka kwa Cathodic.
Igomba gushyirwaho ikimenyetso cyumvikana izina ry'uwayikoze, ubwoko bw'ibikoresho, inomero y'itsinda cyangwa igice cy'ibicuruzwa, itariki yakoreweho, n'uburyo bwo kubibika.
Ahanini ni imiyoboro y'amazi
Ubusanzwe, irangi ryo hanze rikoreshwa mu kurinda imiyoboro kwangirika kw'ibidukikije, mu gihe irangi ryo imbere rikoreshwa mu gukumira kwanduzwa n'amazi, kugabanya imbaraga zo guhangana n'imiyoboro, no kongera igihe cyo kubaho kwayo. Iyi rangi ifasha mu kwemeza ko imiyoboro ikora neza kandi iramba, kubahiriza amahame y'isuku, no kugabanya gukenera kuyibungabunga.
