Electroplated galvanized ceev: kev tsim kho tshiab? 

Koj pom lo lus no ntab ib ncig ntawm cov specs thiab cov ntawv yuav khoom ntau dua tam sim no. 'Sustainable innovation' txuas rau ib yam dab tsi yooj yim li cov txiv ntoo electroplated galvanized. Ua rau koj nres. Puas yog kev lag luam xwb, lossis puas muaj kev hloov pauv tiag tiag hauv cov txheej txheem? Los ntawm kuv lub rooj ntev zaum, sustainability hauv fasteners feem ntau tau nkag siab yuam kev. Nws tsis yog hais txog zinc ntawm cov xov; Nws yog hais txog tag nrho cov saw-los ntawm cov kua qaub da dej ua ntej plating rau cov dej khib nyiab tom qab, thiab seb cov txiv ntoo ntawd puas tau ntev txaus hauv thaj teb los ua pov thawj nws cov hneev taw ntau lawm. Ntau tus xav tias electroplating yog qhov kev xaiv 'greener' vim tias nws muaj ntau thiab tsis tshua muaj peev txheej ntau dua li kub-dip, tab sis qhov ntawd yog qhov kev coj ua. Cov dab neeg tiag tiag yog messier, suav nrog chemistry, lub zog spikes, thiab qee qhov nyuaj nyuaj.

Cov txheej txheem Plating: Qhov twg cov lus nug Sustainability tiag tiag nyob

Cia peb nkag mus rau hauv lub tank, yog li hais lus. Ib tug raug zinc electroplating kab rau txiv ntseej muaj ib tug series ntawm da dej: ntxuav, pickling, plating, chromating (rau qhov xiav-ci los yog daj iridescent tiav), thiab thaum kawg yaug. Kev sib cav txog kev ruaj ntseg tau ua rau muaj kev nyuaj siab nyob rau theem pickling, uas siv hydrochloric los yog sulfuric acid kom tshem tawm xeb thiab nplai. Qhov no ua rau cov kua qaub siv, cov dej khib nyiab pov tseg. Kev tsim kho tshiab tsis yog nyob rau hauv plating nws tus kheej-uas yog ib puas xyoo-laus tshuab-tab sis nyob rau hauv yuav ua li cas koj tswj cov txheej txheem ntxiv. Kaw-loop yaug tshuab, piv txwv li, tuaj yeem txo cov dej siv txog li 90%. Kuv tau pom cov nroj tsuag uas lawv tau siv evaporative rov qab rau lub plating da dej, rub zinc thiab acid rov qab rau hauv kev daws. Nws yog qhov zoo tshaj plaws engineering, tab sis nws yog peev-intensive. ROI yog ntsuas nyob rau hauv xyoo, tsis yog quarters, uas yog ib qho nyuaj muag rau ntau lub khw tsom rau nyias margins ib txhiab daim.

Tom qab ntawd muaj qhov hloov pauv chromate txheej. Qhov no yog cov kauj ruam uas muab cov kev tiv thaiv corrosion tiag tiag, tsim ib txheej rau saum zinc. Cov tsoos hexavalent chromium passivate yog ib qho teeb meem loj ntawm ib puag ncig thiab kev noj qab haus huv. Kev hloov pauv mus rau trivalent chromium lossis txawm tias tshiab dua, chromium-dawb passivations yog qhov kev tsim kho tshiab ruaj khov. Tab sis kev ua tau zoo parity tseem yog kev sib ntaus sib tua. Kuv nco qab txog ib pawg ntawm cov txiv ntoo uas tau kho nrog cov khoom siv chromium-dawb passivate los ntawm cov neeg muag khoom nyob sab Europe rau daim ntawv thov ntug hiav txwv. Cov tshuaj ntsev ntsev cov sij hawm kuaj pom zoo rau ntawm daim ntawv, tab sis daim ntawv tshaj tawm tom qab 18 lub hlis tau pom tias muaj xeb dawb ntxov ntxov. Peb yuav tsum rub lawv. Kev tsim kho tshiab tau nyob ntawd, tab sis qhov kev lees paub tiag tiag tsis yog. Nws tau qhia kuv tias 'sustainable' tsis tuaj yeem tuaj ntawm tus nqi ntawm kev ua haujlwm tsis ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov qauv siv.

Kev siv hluav taws xob yog lwm yam uas ntsiag to. Electroplating yog txheej txheem electrolytic, khiav ncaj qha tam sim no los ntawm kev daws teeb meem. Cov rectifiers muaj zog-dhau. Kuv tau nyob hauv cov chaw uas lawv tau hloov mus rau cov khoom siv hluav taws xob zoo thiab cov mem tes rov qab plating, uas tuaj yeem tso cov zinc ntau sib npaug nrog tsawg zog thiab cov khoom pov tseg. Nws yog ib kauj ruam ruaj khov. Tab sis yog hais tias hluav taws xob yog los ntawm cov hluav taws xob hluav taws xob hluav taws xob, qhov kev suav tag nrho cov pa roj carbon hneev taw yuav tsaus. Koj tuaj yeem muaj qhov ua tau zoo tshaj plaws, xoom-tso plating kab, tab sis yog tias nws tau siv los ntawm lub zog qias neeg, daim ntawv lo "sustainable" xav tias tsis tiav. Qhov no yog qhov chaw tseem ceeb. Ib lub chaw tsim khoom nyob rau hauv ib cheeb tsam nrog lub zog huv si, lossis ib qho kev nqis peev hauv lub hnub ci ntawm qhov chaw, pib nrog lub hauv paus zoo dua.

Cov Khoom Siv thiab Lub Sij Hawm Ntev: Qhov Kev Pom Zoo Metric

Durability yog lub hauv paus ntawm kev ruaj khov rau txhua yam khoom siv. Ib lub txiv ntoo uas corrodes thiab ua tsis tiav hauv tsib xyoos, yuav tsum tau hloov pauv thiab yog li kev tsim khoom ntau dua, yog qhov tsis muaj txiaj ntsig, txawm tias nws cov khoom huv si li cas. Qhov no yog qhov kev xaiv ntawm electroplated thiab mechanical galvanizing (xws li spin galvanizing) tau nthuav. Electroplating muab lub thinner, ntau txheej txheej, zoo rau precision threads thiab aesthetic qhov chaw. Tab sis rau lub luag hauj lwm hnyav, high-corrosion ib puag ncig, txheej nyias nyias tuaj yeem lav. Kuv tau teev cov kub-dip galvanized rau kis ntauwd txiv ntoo txawm tias cov tuab tuab, tsis tshua muaj txheej zoo vim tias kev tiv thaiv kev txi tsuas kav ntev dua. Lub 'innovation' rau electroplating ntawm no tej zaum yuav yog nyob rau hauv advanced alloy coatings-zinc-nickel, zinc-cobalt. Cov no muaj phenomenal corrosion kuj nrog thinner deposits. Peb tau sim zinc-nickel plated txiv ntseej los ntawm ib tus neeg muag khoom hauv Nyij Pooj, thiab cov tshuaj tsuag ntsev tau thawb 1000 teev kom xeb liab, sib tw qee qhov kub-dip specs. Tus ntes? Nqi. Cov nickel ntxiv thiab kev tswj da dej ntau dua tuaj yeem ua tus nqi ob npaug.

Lwm lub kaum sab xis yog cov txiv ntoo substrate nws tus kheej. Nws suab yooj yim, tab sis siv qhov sib xws, zoo siab qis-carbon steel hlau qws ua rau lub ntiaj teb sib txawv. Lub substrate tsis zoo ua rau hydrogen embrittlement txaus ntshai thaum lub sij hawm acid pickling, uas tom qab ntawd yuav tsum tau ci rau embrittlement nyem-lwm nqi zog. Ib tus neeg muag khoom nrog nruj tswj hwm nws cov khoom siv raw, zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd., uas ua haujlwm nyob rau hauv Tuam Tshoj qhov loj tshaj plaws fastener ntau lawm puag, muaj qhov zoo dua qub. Lawv qhov sib thooj rau steel mills thiab kev tsim khoom los ntawm kev kos duab rau kev ntim khoom (https://www.zitaifasteners.com) tso cai rau kom zoo dua traceability thiab zoo sib xws. Qhov no tsis yog ib qho kev hloov pauv tshiab, tab sis nws yog lub hauv paus rau kev tsim tawm kom ruaj khov: ua nws thawj zaug, txo qis kev tsis lees paub thiab rov ua haujlwm dua.

Tom qab ntawd muaj qhov kev txiav txim siab kawg ntawm lub neej, uas tsis tshua muaj leej twg hauv peb cov khoom siv niaj hnub tham txog. Electroplated zinc yog benign. Thaum kawg ntawm lub neej, cov tub ntxhais hlau tau yooj yim rov siv dua, thiab zinc txheej yuav yaj hauv cov yaj. Nws tsis tsim teeb meem paug xws li qee cov txheej txheem. Lub peev xwm ncig no yog qhov chaw ntsiag to hauv nws txoj kev nyiam. Tab sis nws yog passive recycling; Nws tshwm sim vim nws yooj yim thiab kev lag luam, tsis yog vim muaj kev tsim rov qab los. Muaj tseeb tsim-rau-disassembly innovation nyob rau hauv fasteners yog tseem niche, feem ntau nyob rau hauv tsheb.

Case hauv Point: Ntsuas Tus Nqi, Spec, thiab Green Claims

Cia kuv taug kev los ntawm qhov xwm txheej tiag tiag. Peb tab tom nrhiav M20 hex txiv ntseej rau qhov project enclosure sab nraum zoov hauv thaj av uas muaj huab cua nruab nrab. Cov spec hu rau corrosion kuj ntawm 500 teev nruab nrab ntsev tsuag. Cov neeg siv khoom kuj tseem muaj cov lus 'nyiam cov khoom lag luam zoo' hauv RFP. Lub pob yooj yim yog txheem xiav-ci electroplated zinc nrog trivalent chromate. Nws tau ntsib cov spec, pheej yig, thiab peb tuaj yeem khij lub 'tsis muaj hexavalent chromium' lub thawv. Tab sis qhov ntawd puas yog qhov tshiab los yog ruaj khov? Tsis yog tiag. Nws tsuas yog tus qauv tam sim no, txhim kho me ntsis.

Peb thawb rov qab thiab thov ib qho kev xaiv: ib qho me ntsis tuab electroplated txheej (hais, 15μm tsis yog 8μm) nrog cov chromium-dawb organic passivate. Nws ntxiv txog 15% rau cov nqi tsev. Qhov kev txiav txim siab yog qhov kev ua haujlwm ntev dua, txo cov kev hloov pauv. Peb txawm khiav ib pawg me me rau kev sim nrawm. Cov ntaub ntawv txhawb nws. Tab sis tus neeg muas zaub pab neeg yuav khoom balked ntawm tus nqi upfront. Qhov project nyob nrog tus qauv kev xaiv. Zaj lus qhia? Qhov kev tsim kho tshiab muaj nyob rau hauv cov chaw sim thiab hauv cov phau ntawv xav txog yav tom ntej, tab sis kev ua lag luam saws me nyuam raug cuam tshuam los ntawm thawj tus nqi siab. Sustainability xav tau ib qho txiaj ntsig kev txheeb xyuas uas txuas ntxiv dhau qhov kev yuav khoom thawj zaug, thiab qhov ntawd yog kev hloov pauv kev coj noj coj ua qeeb dua li kev hloov kho kab plating.

Qhov no yog qhov chaw manufacturers nrog scale tuaj yeem tsav kev hloov. Ib lub tuam txhab zoo li Zitai, nrog nws qhov ntim thiab kev teeb tsa hauv Yongnian, muaj peev xwm nqus tau qee qhov R & D thiab peev nqi rau cov txheej txheem huv thiab muab lawv ntawm qhov sib tw ntau dua. Lawv qhov chaw nyob ze ntawm txoj kev thauj loj tsis yog hais txog kev thauj mus los rau cov txiv ntoo; nws kuj tseem hais txog kev nkag mus rau kev lag luam dav dav uas tuaj yeem txaus siab them tus nqi me ntsis rau cov kev coj ua zoo dua. Lawv lub tuam txhab profile sau tseg tias lawv nyob hauv plawv ntawm Tuam Tshoj txoj kev lag luam fastener - uas feem ntau ua rau muaj kev sib tw hnyav thiab kev siv cov txheej txheem tshiab sai sai thaum lawv ua pov thawj kev lag luam.

Qhov Kev Txiav Txim Siab: Kev Tshaj Tawm, Tsis Tshaj Tawm

Yog li, rov qab mus rau lo lus nug qub. Puas yog electroplated galvanized txiv ntoo ib qho kev tsim kho tshiab? Kuv lub tswv yim yog qhov no: lub electroplated galvanized ceev lawv tus kheej tsis yog lub innovation. Lawv yog cov khoom lag luam paub tab. Kev tsim kho tshiab tau tshwm sim - nce ntxiv, tsis sib xws - nyob ib puag ncig lawv cov khoom siv hauv tsev thiab hauv kev tsim cov txheej txheem siab heev. Peb tab tom pom kev tswj cov dej khib nyiab zoo dua, theem tawm ntawm cov tshuaj lom neeg tsis zoo, thiab siv zog ntau dua. Cov no yog cov txheej txheem tshiab uas ua rau cov khoom uas twb muaj lawm ruaj khov.

Qhov kev ntsuam xyuas tseeb yog seb qhov kev txhim kho no dhau los ua kev lag luam hauv paus lossis tseem muaj kev xaiv hwm. Rau qhov tshwm sim, cov neeg siv kawg yuav tsum muaj nuj nqis thiab qhia cov yam ntxwv hauv qab-xws li 'plated nrog trivalent chromate nyob rau hauv ib qho chaw nrog xoom kua paug' - tsis yog tus nqi thiab daim ntawv lo 'ntsuab'. Nws kuj tseem xav kom cov tuam txhab lag luam ua pob tshab txog lawv cov txheej txheem, uas ntau yam tseem tsis tau.

Thaum kawg, hu rau tus qauv electroplated txiv ntoo 'sustainable innovation' feem ntau yog ib qho stretch. Tab sis kev lag luam tab tom txav mus, ib qho los ntawm ib qho, lub tank los ntawm lub tank, mus rau kev tsim khoom ruaj khov. Cov txiv ntoo zoo ib yam hauv lub thawv, tab sis zaj dab neeg tom qab nws maj mam hloov. Qhov ntawd yog qhov kev ntsuas tseeb tshaj plaws uas koj yuav tau txais los ntawm ib tus neeg uas tau siv sijhawm ntau dhau los tshuaj xyuas cov ntawv pov thawj plating thiab cov ntawv ceeb toom tsis ua haujlwm. Lub innovation yog nyob rau hauv lub grind, tsis yog gloss.
