Iyo wunvise flangine flange, abantu benshi bahita batekereza kurinda ruswa, wenda ikiguzi. Inguni y'ibidukikije? Akenshi nyuma yo gutekereza, cyangwa nabi, kutumva nabi. Nabonye amaduka afata ibigega bya electroplating rinse nkundi murongo wamazi, kandi niho hatangirira inkuru nyayo-nibibazo nyabyo. Ntabwo ari ibijyanye na zinc gusa.

Ikibazo Cyibanze Ntabwo ari Icyuma gusa

Reka tubyumve neza: umutwaro wibanze wibidukikije uva kuri electroplating galvanized flanges ntabwo mubisanzwe zinc ubwayo. Zinc isa neza ugereranije nibindi byuma bisa nka kadmium cyangwa chromium ya hexavalent. Ingaruka ziri mubikorwa. Ibyiciro mbere yo kuvura-gutoragura aside kugirango ikureho ingese, isukari ya alkaline yo gusiga amavuta - itanga imyanda ya mbere yimyanda. Urimo gukemura ubwogero bwa aside yakoresheje buremereye hamwe na chloride ya fer na sulfate, hamwe na alkali yogejwe yuzuye amavuta na surfactants. Niba ibyo bigiye kuvoma bitavuwe, urareba ihungabana rikomeye rya pH no kugabanuka kwa ogisijeni mumazi. Ndibuka iduka rito ryakazi hafi ya parike yinganda yaciwe amande atari kuri zinc, ahubwo ni metero pH asoma imbonerahamwe yavuye mumatara yabo yajugunywe.

Noneho haza kwiyuhagira. Mugihe isahani ya alkaline itari cyanide isanzwe isanzwe (ubwogero bwa cyanide ninzozi mbi zahise, dushimire), ubwogero buracyangirika. Amashanyarazi, ibikoresho bigoye, hamwe nogukoresha amazi aravunika, akora ibinyabuzima bikenera kuvurwa. Gukurura-iyo firime yoroheje yumuti ifatanye na flange iyo ikuweho-ni nyirabayazana ucecetse. Iratonyanga, yanduza amazi. Twakunze gutekereza ko inzira yoroshye yo gutonyanga yari ihagije kugeza igihe ubugenzuzi bwabandi bantu bwerekanaga kwanduzanya hamwe na coolant ziva mumashini. Byari akajagari.

Urukurikirane rwo kwoza ni ngombwa. Kwiyuhagira-bigezweho bikiza amazi, ariko niba igipimo cyimigezi kidahinduwe neza, uba wimuye umwanda uva mukigega ujya mubindi. Ikosa rikomeye nabonye? Dufate ko amazi meza asukuye bisobanura amazi meza. Amashanyarazi ashonga hamwe nibyuma bigoye ntibigaragara. Nagerageje amazi meza yoza agifite 20-30 ppm ya zinc, hejuru yumupaka usohoka. Nubwoko burambuye ufata gusa nibisanzwe, isesengura ryiza, ntabwo ari igenzura.

Imyanda yimyanda nigiciro cyihishe

Umuyoboro. Nibyo bicuruzwa byanyuma byanze bikunze. Iyo uhinduye amazi mabi, zinc yashonze igwa nka hydroxide. Bishyizwe mu myanda ishobora guteza akaga mu turere twinshi bitewe n’ibyuma byayo ndetse n’ubushobozi bwo gutemba. Igiciro ntabwo kiri mu gisekuru cyacyo gusa; biri mubikorwa, impapuro (gukurikirana kugaragara), n'amafaranga yo kujugunya. Igikorwa giciriritse gikora plang flanges kugirango gikoreshwe muburyo gishobora kubyara toni nyinshi ziyi silge kumwaka. Ibiciro by'imyanda byazamutse cyane. Ndibuka umushinga aho ikiguzi cyo kujugunya cyatangiye guhangana nigiciro cyibikoresho bya zinc anode. Ukwo kwari uguhamagarwa kugirango turebe gukira.

Gukoresha amazi nizindi ngaruka zihishe. Amashanyarazi afite inyota. Ku murongo usanzwe wa rack, amazi yogeje arashobora kuba menshi. Mu bice bifite amazi make cyangwa ibiciro biri hejuru, ibi bihinduka ikiguzi cyibikorwa bitaziguye kandi nikibazo kirambye. Twakoranye n'ikigo, ntabwo bitandukanye nibyo wasanga mubikorwa bikomeye byo gukora nka Hamagara zitai yihuta ukora co., Ltd. muri Yongnian, aho abayobozi baho batangiye gukaza ibyemezo byo kuvoma amazi yubutaka. Bagombaga gushora imari muri sisitemu yo gufunga no gufunga ion, yari ifite capex ndende ariko igabanya amazi yabo hejuru ya 70%. Yatanze umusaruro mu myaka ibiri.

Ingufu nicyo kintu kitaganiriweho. Gushyushya tanki, gukosora imbaraga za DC, guhumeka kugenzura ibicu - byose byiyongera. Ikirenge cya karubone gihuza imbaraga za gride yaho ivanze. Mu karere gakoreshwa ahanini n’amakara, ingaruka z’ibidukikije zitaziguye zo guteranya ikintu cya flanges zirashobora kuba ingirakamaro. Ni ikinyuranyo cyibitekerezo byubuzima: twibanze kuri chimie yo koga ariko akenshi twirengagiza ibyuka byamashanyarazi inyuma yumuriro w'amashanyarazi.

Kurubuga-Kubyukuri no Kunanirwa gufatika

Mubyigisho, sisitemu yo kuvura nigisubizo. Mubimenyerezo, akenshi ntibabungabunzwe cyangwa ntibasobanukirwe. Ikintu gikunze kugaragara mubihingwa bishaje: ushinzwe gutunganya amazi mabi nayo ni umushoferi wa forklift. Barimo bajugunya ibyuma bya pH bishingiye kubizamini byihuse, biganisha ku guhindagurika kwangiza imvura. Igisubizo? Zinc kunyerera mu bisobanuro, cyangwa gukora akavuyo katayungurura neza. Nabonye imashini zungurura zifunze akajagari ka gelatinous kuko pH yibeshye mugihe cyimvura, ihuza inzira yose yo gutunganya imyanda muminsi.

Noneho hariho ibishuko byo guca inguni. Guhumeka mu bigega bifunguye kugirango ugabanye amazi y’amazi byumvikana nkigitekerezo gihenze. Ni, kugeza ubonye ko yibanda gusa kubihumanya no kurekura ibintu byose bihindagurika mukirere gikikije iduka. Ntabwo ari igisubizo cyiza. Ikindi kigeragezo cyatsinzwe nabonye kirimo gukoresha polymer magic kugirango uhuze byose. Cyakoze neza, gifata amazi menshi kuburyo ingano ya siliveri yiyongereyeho 40%, itsinze intego. Nta gukosora isi yose; ikeneye guhuzwa na chimie yihariye yo kwiyuhagira no kwoza.

Ibikoresho biva mu mahanga byongera urundi rwego. Zinc anode ituruka he? Bituruka ku gushonga kwambere cyangwa gutunganya? Ubucukuzi bw'amabuye y'agaciro hamwe no gushonga inkumi zinc ni nini cyane. Ukoresheje icyiciro cya kabiri, cyongeye gukoreshwa zinc irashobora kugabanya cyane umutwaro wo hejuru wibidukikije. Nicyemezo cyamasoko amaduka menshi yisahani atagenzura, ariko inganda nini zishakisha ibice byashizweho, nkisosiyete yihuta icunga imiyoboro yabyo, irashobora rwose kandi igomba gutekereza. Urubuga rwa Zitai (https://www.zitaifacens.com) yerekana aho biherereye mubushinwa bunini busanzwe; abaproducer nini nini bafite imbaraga zo gusaba ibicuruzwa bisukuye kubacuruza amasahani, bigatuma urunigi rwose rugana kubikorwa byiza.

Amabwiriza nintego yimuka

Kubahiriza ntabwo bihamye. Muri EU, amabwiriza ya REACH na ELV ahora ashiraho igitutu, yibanda kumurika cyangwa inyongeramusaruro. Muri Reta zunzubumwe za Amerika, imipaka ya POTW (Imirimo ifata abantu benshi) irashobora gukomera kuruta amabwiriza ya EPA. Nagize umukiriya wujuje imyaka, noneho itegeko rishya ryaho ryagabanije imipaka yemewe ya zinc igice. Bagombaga kuvugurura uruganda rwabo rwose rwo kuvura. Ikiruhuko? Ntushobora gushiraho sisitemu gusa ukayibagirwa. Ugomba gukurikirana imigendekere yubuyobozi. Ingaruka ku bidukikije ni nk’ingaruka zemewe n’amategeko nko ku bidukikije.

Gutanga raporo no gukorera mu mucyo biragenda bigira ingaruka. Abafatanyabikorwa, kuva ku bakiriya kugeza ku baturage, bashaka kumenya. Nabonye RFQ nyinshi (Gusaba Quotation) kubitangwa bya flange birimo igice kijyanye na sisitemu yo gucunga ibidukikije nicyemezo cyo guta imyanda. Irimo kuva mubibazo byubahiriza ibiro byujuje ibyangombwa byo kugurisha imbere. Ubushobozi bwumukoresha wo kuvuga uburyo bayobora ingaruka ku bidukikije y'ibikorwa nka electroplating ihinduka isoko itandukanye.

Ibi biganisha ku gitekerezo cyo guhindura imitwaro. Mugukora flange irwanya ruswa ikoresheje galvanizing, urashobora kwagura ubuzima bwumurimo, kugabanya inshuro zo gusimburwa ningaruka zijyanye ninganda. Nibyo ubuzima bwiza bwinzira yubucuruzi. Ariko niba isahani ubwayo yanduye, ushobora kuba utera ikibazo kinini imbere kugirango gikemure gito nyuma. Impirimbanyi iroroshye kandi ikeneye isuzumwa ryukuri, ryuzuye, ntabwo ryibanda gusa kumazi ahita.

Kugana Mitiweli: Nta masasu ya feza, gusa akazi gakomeye

None, ni iki gikora? Icyambere, kugabanya isoko. Kunoza chimie yo kwiyuhagira kugirango wongere ubuzima, kunoza racking kugirango ugabanye gukurura, no gushiraho imiti yo gutera cyangwa ibyuma byo mu kirere mbere yuko tank ishobora kugabanya umwanda ku isoko 30% cyangwa irenga. Nubuhanga butangaje, ariko nintambwe nziza.

Icya kabiri, gukira. Guhana kwa Ion, kugarura ibyuka, cyangwa tekinoroji ya membrane irashobora gukurura zinc namazi gusubira mubikorwa. Ubukungu ubu ni bwiza muri byinshi. Urufunguzo ni ugushushanya kugarura imyanda yawe yihariye. Sisitemu yagenewe kwiyuhagira-chloride nyinshi irashobora kunanirwa ku bwogero bushingiye kuri sulfate.

Hanyuma, kuvura neza-kuvura neza, bifite ubunini kandi bigakorwa nabakozi bahuguwe. Uru ni urushundura. Gufatanya numuntu uzwi wimyanda yimyanda ntabwo biganirwaho. Intego igomba kuba iyo neti ntoya ishoboka binyuze mubyiciro bibiri byambere.

Mu kurangiza, ingaruka z’ibidukikije ziterwa na electroplating galvanised flanges nikibazo gishobora gucungwa ninganda, ariko nticyoroshye. Irasaba inzira-murwego rwo gusobanukirwa irenze kurangiza kuruhande. Byerekeranye na chimie iri mu kigega, amazi yogeje, isuka mu binini, n'ibyemezo bifatwa buri munsi mu iduka. Kwirengagiza ni akaga; kuyicunga ni igice cyo gukora ibicuruzwa biramba neza. Ihuriro ry’inganda, kimwe n’i Handan aho amasosiyete nka Zitai akorera, afite igipimo cyo guhindura impinduka zifatika niba intego yibanze aho. Ntabwo ari ugukuraho inzira, ahubwo ni uguhuza igiciro cyayo-ibidukikije n'ibikorwa-muburyo twubaka ibintu.
