Paunonzwa galvanized flange, vanhu vazhinji vanobva vafunga kuchengetedzwa kwekuora, pamwe mutengo. Kona yezvakatipoteredza? Kazhinji kufunga pashure, kana kuti zvakatoipisisa, kusanzwisiswa. Ndakaona zvitoro zvinobata matangi e-electroplating rinse seimwe mutsara wemvura, uye ndipo panotangira nyaya chaiyo-uye matambudziko chaiwo. Haisi chete nezve zinc.

Iyo Core Nyaya Haisi Ingori Metal

Ngativei zvakajeka: iyo yekutanga yezvakatipoteredza mutoro kubva ku electroplating galvanized flanges haisi iyo zinc yekuzviputira pachayo. Zinc ine hunyoro kana ichienzaniswa nemamwe masimbi ekuputira senge cadmium kana hexavalent chromium. Kukanganisa kuri mukuita. Matanho ekutanga ekurapa — kunhonga asidhi yekubvisa ngura, alkaline yekuchenesa girisi — inoburitsa marara ekutanga. Uri kubata nekugezeswa kweasidhi kunorema nesimbi chlorides uye sulfates, uye alkali mabhati akatakurwa nemafuta uye surfactants. Kana izvo zvikaenda pakudonha zvisina kubatwa, iwe uri kutarisa yakanyanya kukanganiswa pH uye kupera kweokisijeni mumiviri yemvura. Ndinoyeuka chitoro chidiki chebasa padhuze nepaki yemaindasitiri ndichibhadhariswa faindi kwete yezinc, asi yemamita pH kuverenga kubva pamachati kubva mudhangi ravo rekurasira.

Ipapo kunouya kugeza plating. Nepo alkaline isiri-cyanide zinc plating ikozvino yakajairika (cyanide mabhati inotyisa yekare, nekutenda), iyo yekugezera ichiri kushatisa. Zvinopenya, zvinoomesa zvinhu, uye zvinonyorovesa zvinoputsika, zvichigadzira organic komisheni inoda kurapwa. Iyo yekukwevera kunze-iyo firimu rakatetepa remhinduro yakanamatira kune flange kana yabviswa- imhosva yakanyarara. Inodonhedza, ichisvibisa pasi pasi. Isu taifunga kuti tireyi yakapfava yaikwana kudzamara ongororo yebato rechitatu yaratidza kusvibiswa-kwakasvibiswa neinotonhorera kubva munzvimbo yekugadzira. Yakanga iri bongozozo.

Rining sequence yakakosha. Counter-ikozvino rinsing inochengetedza mvura, asi kana mazinga ekuyerera asina kuenzaniswa zvakanaka, uri kungofambisa tsvina kubva kune rimwe tangi kuenda kune rimwe. Kukanganisa kukuru kwandakaona? Kufunga kuti mvura yakachena inosuka zvinoreva mvura yakachena. Zvimedu zvakanyungudutswa uye masimbi akaomarara hazvioneki. Ndakaedza mvura yakachena yekugezesa iyo ichiri akabata 20-30 ppm ye zinc, iri pamusoro pekubuda. Ndiyo mhando yeruzivo rwaunongobata chete neyakajairwa, ongororo yakakodzera, kwete cheki yekuona.

Kurasa Hova uye Mari Yakavanzwa

Sludge. Ndicho chisingadzivisiki kuguma chigadzirwa. Kana iwe ukasadzikamisa mvura yetsvina, iyo zinc yakanyungudika inonaya se hydroxide sludge. Inoratidzirwa semarara ane ngozi mumatunhu mazhinji nekuda kwemukati mesimbi uye mukana wekudonha. Mutengo hausi muchizvarwa chayo chete; iri mukubata, mapepa (manifest tracking), uye mari yekurasa. Iyo yepakati-saizi oparesheni yekuisa maflange ekushandiswa kwemaitiro anogona kugadzira akati wandei matani eiyi tsvina pagore. Mari yekurasira marara yakakwira zvakanyanya. Ndinorangarira purojekiti apo mari yekurasa marara yakatanga kukwikwidza mutengo wezvigadzirwa zvezinc anode. Ndiko kwaiva kumuka kuti nditarise kupora.

Kushandiswa kwemvura ndechimwe chinokanganisa chakavanzika. Electroplating ine nyota. Kune yakajairwa rack line, kuyerera kwemvura yekugeza kunogona kuve kwakakura. Munzvimbo dzine kushomeka kwemvura kana mitero yakakwira, izvi zvinova mutengo wakananga wekushandisa uye inyaya yekuenderera mberi. Takashanda nechinzvimbo, kwete kusiyana nezvawaizowana panzvimbo huru yekugadzira senge Handan Zitai Fastener Kugadzira Co, Ltd. muYongnian, uko zviremera zveko zvakatanga kuomesa zvibvumirano zvekuchera mvura yepasi. Vaifanira kuisa mari mune yakavharwa-loop rinse system ine ion exchange, yaive nepamusoro capex asi yakacheka makeup emvura neanopfuura 70%. Yakabhadhara mukati memakore maviri.

Simba ndiro rinonyanya kukurukurwa. Kudziya kwetangi, zvigadziriso zvesimba reDC, kufefetedza kwekudzora mhute-zvese zvinowedzera. Iyo kabhoni tsoka inosungirirana kumashure kune yemuno gidhi musanganiswa wesimba. Munzvimbo inofambiswa zvakanyanya nemarasha, iyo isina kunanga kwezvakatipoteredza kukanganisa kwekuputira mudziyo wemaflange kunogona kuve kwakakosha. Igap rekufunga kwehupenyu: isu tinotarisa pane yekugezesa chemistry asi tinowanzo kufuratira kuburitswa kwesimba remagetsi kuseri kwemagetsi ari kumhanyisa mutsara.

Pa-Saiti Chokwadi uye Kutadza Kunoshanda

Mukutaura, maitiro ekurapa ndiwo mhinduro. Mukuita, ivo vanowanzove vasina kuchengetedzwa kana kusanzwisiswa. Chinhu chinowanzoitika muzvirimwa zvekare: mushandisi wekuchenesa mvura yetsvina ndiye zvakare mutyairi weforklift. Ivo vari kurasa pH zvigadziriso zvichibva paye kukurumidza tambo bvunzo, zvichitungamira kune emusango kuzununguka kunovhiringidza maitiro emvura. Zvakaguma nei? Zinc inotsvedza kuburikidza nekujekesa, kana kugadzira sludge isingazosefa zvakanaka. Ndakaona mafineta akavharwa negelatinous mess nekuti iyo pH yaive isiriyo panguva yekunaya, ichisunga iyo yese nzira yekubata tsvina kwemazuva.

Ipapo kune muedzo wekucheka makona. Evaporation mumatangi akavhurika kuderedza mvura yetsvina inonzwika senge pfungwa yakachipa. Ndizvozvo, kusvikira iwe waona kuti ingori kungoisa zvinosvibisa uye kuburitsa zvese zvinopenga mumhepo yakatenderedza chitoro. Haisi mhinduro yakanaka. Imwe kuyedza yakakundikana yandakaona ichibatanidza kushandisa mashiripiti polymer kugadzika zvese. Yakashanda zvakanyanya, ichiteya mvura yakawandisa zvekuti sludge volume yakawedzera ne40%, ichikunda chinangwa. Iko hakuna kugadzirisa kwepasirese; inoda kugadzirwa kune chaiyo yekugezera chemistry uye sukurudza setup.

Material sourcing inowedzera imwe layer. Zinc anode inobva kupi? Inobva pakunyungudutswa kwekutanga here kana kuti kushandiswazve? Kucherwa nekunyungudutswa kwetsoka dzevirgin zinc yakakura kwazvo. Uchishandisa yechipiri, yakadzokororwa zinc anode inogona kudzikisa zvakanyanya kuremerwa kwezvakatipoteredza. Isarudzo yekutenga zvinhu izvo zvitoro zvakawanda zveplating hazvidzore, asi vagadziri vakakura vanotsvaga zvikamu zvakapfava, sekambani yefastener inotarisira kugovera kwayo, inogona uye inofanirwa kufunga. Webhusaiti ye Zitai Forteners (https://www.zitafornasteers.com) inoratidzira nzvimbo yavo muChina yakakura yakajairwa chikamu base; vagadziri vakakura vakadai vane simba rekuda zvinhu zvakachena kubva kune vatengesi vavo veplating, vachisundira cheni yese kune maitiro ari nani.

Regulations uye Moving Target

Kuteerera hakuna kumira. MuEU, REACH uye ELV dhairekitori inogara ichimanikidza maumbirwo, yakanangana nezvinopenya kana zvinowedzerwa. MuUS, miganhu yenzvimbo (Public Owned Treatment Works) inogona kuomarara kudarika federal EPA nhungamiro. Ndakave nemutengi aienderana kwemakore, zvino mutemo mutsva wepanzvimbo wakaderedza muganhu unobvumirwa we zinc nehafu. Vaifanira kudzoreredza mushonga wavo wese. The takeaway? Iwe haugone kungoisa system uye kuikanganwa. Iwe unofanirwa kutarisa maitiro ekugadzirisa. Kukanganisa kwezvakatipoteredza kwakawanda nezvenjodzi yepamutemo sezvazviri nezve ecology.

Kuzivisa uye kubuda pachena kuri kuita chikamu chemhedzisiro. Vanobatanidzwa, kubva kune vatengi kuenda munharaunda, vanoda kuziva. Ndakaona mamwe maRFQs (Chikumbiro cheQuotesheni) yekupihwa kweflange inosanganisira chikamu chemaitiro ekutonga kwezvakatipoteredza uye zvitupa zvekurasa tsvina. Iri kushanduka kubva ku-back-office yekuteerera nyaya kuenda kumberi-yekupedzisira yekutengesa qualification. Kugona kwemugadziri kutaura mabatiro avanoita kwezvakatipoteredza kukanganisa yemaitiro akaita se electroplating iri kuita musiyano wemusika.

Izvi zvinotungamirira kune pfungwa yekuchinja mitoro. Nekuita kuti flange irambe isingadziviriri kuburikidza nekuisa galvanizing, unogona kuwedzera hupenyu hwayo hwesevhisi, uchidzikisa kuwanda kwekutsiva uye zvinosanganisirwa mukugadzira zvinokonzeresa. Ndiko kutengeserana kwakanaka kwehupenyu-kutenderera. Asi kana iyo plating process pachayo yakasviba, unogona kunge uchigadzira dambudziko rakakura kumberi kugadzirisa diki gare gare. Chiyero chakapfava uye chinoda kutendeseka, kuzere-kutenderera kuongororwa, kwete kungotarisa pamvura inoyerera yewekishopu.

Kuenda Kuderedza: Hapana Mabara eSilver, Kungoshanda nesimba

Saka, chii chinoshanda? Kutanga, kuderedza sosi. Kunatsiridza kemikari yekugezesa kuti iwedzere hupenyu, kuvandudza racking kuderedza kudhonza-kunze, uye nekuisa spray rinses kana mapanga emhepo tangi isati yacheka kusvibiswa panzvimbo ne30% kana kupfuura. Injiniya isina kunaka, asi inhanho inoshanda zvakanyanya.

Chechipiri, kupora. Ion exchange, evaporative kudzoreredza, kana membrane tekinoroji inogona kudhonza zinc nemvura kudzokera mukuita. Economics ikozvino yakanakira mune dzakawanda zviitiko. Chinokosha kugadzira kudzoreredza kune yako chaiyo marara. A sisitimu yakagadzirirwa bhati yepamusoro-chloride inogona kukundikana pane sulfate-based bath.

Pakupedzisira, kurapwa kwakakodzera kwepombi, kwakakura zvakanaka uye kushandiswa nevashandi vakadzidziswa. Iyi ndiyo mambure ekuchengetedza. Kudyidzana nemunhu ane mukurumbira wemarara hakutaurike. Chinangwa chinofanira kunge chiri chekuita kuti mambure aya ave madiki sezvinobvira kuburikidza nematanho maviri ekutanga.

Pakupedzisira, kukanganisa kwezvakatipoteredza kwe electroplating galvanized flanges idambudziko rinogoneka remaindasitiri, asi riri kure nekureruka. Inoda nhanho-nhanho nzwisiso inoenda kupfuura kupedzisa pachikamu. Zviri pamusoro pekemikari mutangi, mvura yemugetsi, sludge mubhini, uye sarudzo dzinoitwa zuva rega rega pauriri hwechitoro. Kuifuratira kune ngozi; Kuchigadzirisa chingori chikamu chekugadzira chigadzirwa chinogara kwenguva refu zvine hungwaru. Nzvimbo dzeindasitiri, senge iri kuHandan uko makambani akaita seZitai anoshanda, ane chiyero chekufambisa shanduko ine musoro kana chinangwa chikaiswa ipapo. Hazvisi zvekubvisa maitiro, asi nezvekubatanidza mutengo wayo chaiwo-zvakatipoteredza uye zvinoshanda-munzira yatinovaka nayo zvinhu.
