Zovala zakuda za zinc-zokutidwa ndi flange: kusankha kokhazikika? 

Mukuwona 'zinc wakuda' ndi 'zokhazikika' m'chiganizo chomwecho masiku ano. Zimakupangitsani kuti muyime. Kuchokera pomwe ndikuyimilira, nditapeza ndikuzifotokozera chilichonse kuyambira m'mabwalo akunja mpaka kumabulaketi omangika, yankho lenileni silili pazamalonda. Zili mu kabati yopopera mchere, mtengo wonse wa cholumikizira cholephera, ndipo moona mtima, njira zopezera gulu lomaliza lokhazikika pambuyo pa batch. Tiyeni tidutse mu greenwash.

Kumaliza Kokha: Kuposa Mtundu Wokha

Kupaka zinki wakuda si chinthu chimodzi. Nthawi zambiri amakhala wosanjikiza wa zinki wokhala ndi zokutira zosintha zakuda za chromate. Gawo la 'chromate' ndilo mbendera yofiira yokhazikika kwa ambiri. Ma chromate akale amakhala ndi hexavalent chromium, chiwopsezo chachikulu cha chilengedwe komanso thanzi. Makampaniwa asunthira kwambiri ku ma chromates ang'onoang'ono pa sitepe yakuda, yomwe ndikusintha kotsimikizika. Koma 'kupititsa patsogolo' sikufanana ndi 'wobiriwira'. Ikadali njira yambiri yama electrochemical yomwe imaphatikizapo ma acid, ma rinses, ndi madzi oyipa omwe amafunikira chithandizo chachikulu.

Ndikukumbukira pulojekiti yopangira makabati am'mphepete mwa nyanja. Spec adayitanira mabawuti akuda a zinc okhala ndi flange kwa kukana dzimbiri ndi mawonekedwe otsika. Gulu loyamba lochokera kwa ogulitsa linkawoneka bwino koma lidayamba kuwonetsa dzimbiri lofiira pamiyezi isanu ndi umodzi. Kulephera? Chosanjikiza chakuda cha chromate chinali chowonda kwambiri, pafupifupi chokongoletsa. Mbali yokhazikika idagwa nthawi yomweyo - kusinthidwa koyambirira kunatanthauza kuwirikiza kawiri zinthu, kutumiza, ndi ntchito.

Kukhazikika ndiye chinsinsi cha zonena zokhazikika pano. Bawuti yakuda ya zinki yokonzedwa bwino yokhala ndi zinki yokhuthala mokwanira komanso chosindikizira cholimba (nthawi zambiri chovala chowonjezera chapamwamba) chimatha zaka zambiri m'malo ochita dzimbiri. Kukhala ndi moyo wautali kumalepheretsa kusintha. Koma mukugulitsa mtengo wachilengedwe wokonzekera zam'tsogolo kwa moyo wautali wautumiki. Ndizoyenerana, osati kupambana momveka bwino.

Supply Chain ndi Zowona Zothandiza

Apa ndi pamene chiphunzitso chimakumana ndi fakitale. Kukhazikika kowona kuyenera kuphatikiza ma mailosi a carbon pa cholumikizira. Ichi ndichifukwa chake kuyandikira kwa malo opangira zinthu ndikofunikira. Malo ngati Chigawo cha Yongnian ku Handan, Hebei-ndiwo malo oyambira kupanga zomangira ku China. Ngati mukuyang'ana kuchokera pamenepo, mukulowa mu chilengedwe chokhazikika. Kugwira ntchito bwino kuchokera kwa ogulitsa m'magulumagulu kupita kudoko lalikulu kumatha kuchepetsa kwambiri utsi wamayendedwe poyerekeza ndi kupeza kuchokera kumayendedwe amwazikana.

Ndagwira ntchito ndi opanga omwe ali kumeneko, monga Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd.. Malo awo, moyandikana ndi njanji zazikulu ndi misewu, si mzere chabe pamakampani awo (https://www.zitaifasteners.com). Zimatanthawuza kusungirako zogwirika ndi kudalirika. Kwa dongosolo lapamwamba kwambiri la mabawuti a flange, kudalirika kumeneko kumatanthauza kuti simukuyitanitsa mochulukitsira ‘ngati zichitika,’ kuchepetsa zinyalala. Kuyang'ana kwawo monga opanga zazikulu pa mazikowo nthawi zambiri kumatanthauza kuwongolera njira bwino pamizere yopangira, zomwe zimachepetsa kukana - njira ina yochepetsera zinyalala.

Koma apa pali hiccup yothandiza: kusasinthasintha kwamtundu. Zinc wakuda siwofanana ndi galvanizing yotentha. Mutha kusintha kuchokera ku batch kupita ku batch, nthawi zina ngakhale mkati mwa batch. Kwa mapulogalamu omwe aesthetics amafunikira, izi zitha kuyambitsa kukanidwa. Ndawona mapallet onse akukana chifukwa mtundu wakuda sunafanane ndi zomwe zidatumizidwa kale. Ndiko kulephera kokhazikika - mabawuti onse okonzedwawo amakhala opanda kanthu kapena akufunika kukonzanso. Kodi tikuphunzirapo chiyani? Kuti mukhale okhazikika, choyimira chanu chiyenera kulola kusiyanasiyana kwamitundu yachilengedwe, kapena muyenera kuyanjana ndi mbale yokhala ndi njira zowongolera bwino.

Kufananiza Njira Zina: Mawonekedwe Owona Mwankhanza

Kodi zinki wakuda ndiye mapeto okhazikika osagwira dzimbiri? Osati mwa kuwombera nthawi yayitali. Plain mechanical galvanizing (zinki) nthawi zambiri imakhala yolimba ndipo imakhala ndi njira yosavuta, yopanda poizoni, koma ndi siliva. Chitsulo chosapanga dzimbiri (A2, A4) ndi cholimba kwambiri komanso chogwiritsidwanso ntchito, koma kupanga kwake kumafuna mphamvu zambiri, ndipo kumatha ndulu. Kutentha kwa dip galvanizing ndi kolimba koma kochuluka ndipo kumatha kusokoneza kulolerana.

Tinayesa kusintha makina oyika pafamu ya solar kuchoka pa zinki wakuda kupita ku zosapanga dzimbiri. Lipoti lokhazikika limawoneka labwino kwambiri: lotha kubwezeretsedwanso, lokhalitsa. Pa pepala. M'mundamo, vuto lowopsa pakukhazikitsa linali lotopetsa. Tinadutsa m'mabowo ndi matepi, kuwononga maola a anthu, ndipo tinachedwa kuyika. Mtengo wa carbon wa kuchedwa kumeneku ndi kuvala kwa zida mwina sikunawononge ubwino wake. Tinabwerera ku zinc yakuda yakuda yokhala ndi topcoat yowoneka bwino. Zinagwira ntchito, ndipo mtengo wa carbon woikidwa unali wotsika.

The chisankho chokhazikika sikutanthauza kusankha zinthu ‘zobiriwira kwambiri’ m’malo opanda kanthu. Zimakhudza dongosolo lonse: kupangidwa, kukhazikitsa, moyo wautali, ndi kutha kwa moyo. Nthawi zina, njira yosawoneka bwino pamapepala ngati zinki wakuda ndiyokhazikika pakuchita chifukwa imagwira ntchito modalirika koyamba.

Mapeto a Moyo Equation

Zokambidwa kawirikawiri, koma zofunika. Pamapeto a moyo, a wakuda zinki-yokutidwa bawuti akadali chitsulo chachitsulo chokhala ndi zokutira zopyapyala za zinki. Ikhoza kubwezeretsedwanso ngati zitsulo zopanda pake. Zinc wosanjikiza adzakhala oxidize mu kusungunuka. Sizili ngati bawuti yokhala ndi polima yomwe imatha kuwononga mtsinje wazaka. Ichi ndi mfundo yake. Zitsulo zolemera kuchokera ku plating ndi vuto lakumtunda, lomwe limayendetsedwa (mwachiyembekezo) ndi machitidwe opangira zinyalala za mbale.

Ndidayendera malo opangira zida zamagetsi zomwe zidachotsedwa. Milu ya mabulaketi ndi mabawuti, ambiri okhala ndi zinki wakuda wakuda. Anangong'ambika n'kutumizidwa kuchigayo. Palibe kusamalira kwapadera. Kuchokera pakuwona chuma chozungulira, ndizowongoka. Zovuta, ndi kulemedwa kwa chilengedwe, zinali zitatsekedwa kale panthawi yopanga. Izi zimakankhira funso lokhazikika pafupifupi kubwerera ku gawo lopanga.

Ndiye, kodi munganene kuti zokhazikika? Pokhapokha ngati wopanga ali ndi udindo. Muyenera kuwafunsa za mankhwala awo amadzi otayira, kugwiritsa ntchito kwawo trivalent vs. hexavalent chromate, gwero lawo lamphamvu. Wopanga m'mafakitale okhazikika ngati Yongnian nthawi zambiri amawunikiridwa kwambiri ndi chilengedwe chifukwa cha kukula kwake, komwe kumatha kukhala chinthu chabwino. Si zangwiro, koma ndi chifukwa.

Kutsiliza: Kukhazikika kokhazikika, kothandiza

Choncho, kubwerera ku mutu. Kodi mabawuti akuda okhala ndi zinc ndi chisankho chokhazikika? Yankho ndi inde zokhazikika, koma ndi chenjezo lalikulu. Kukhazikika kwawo sikuli kwachibadwa; zimatengera magwiridwe antchito. Zimatengera njira yopangira plating yabwino yomwe imatsimikizira moyo wautali, njira zoperekera zinthu zomwe zimachepetsa zinyalala ndi ma kilomita a kaboni, komanso wopanga wodalirika yemwe amawongolera njira zake zama mankhwala.

Sadzapambana mphoto iliyonse ya 'greenest tech'. Koma m'dziko lenileni la zomangamanga, kupanga, ndi zomangamanga, komwe kulephera ndiye njira yomaliza ya zinyalala, boti yakuda yakuda yodziwika bwino nthawi zambiri imakhala yothandiza kwambiri ndipo, mwanjira yamoyo wonse, ndiye chisankho chokhazikika chomwe chilipo pantchitoyo. Ndi chida, osati chikho. Mumachisankha pamene mawonekedwe ake enieni - kukana kwa dzimbiri, kutsekereza, kukongola, ndi mtengo wake - agwirizane kuti apewe mtengo wokulirapo wa chilengedwe. Ndiko kuyitanira kwenikweni kwa chiweruzo.

Nthawi ina mukadzalemba zina, yang'anani kupyola dzina lomaliza. Gwirani muyeso wa plating, malipoti oyeserera, ndikuwona komwe amapangidwira komanso momwe amapangidwira. Ndipamene funso lokhazikika limayankhidwa, osati mu dzina lazogulitsa. Kuti mupeze kuchuluka kwa ma voliyumu, kuyang'ana opanga ophatikizidwa m'magulu akulu ngati omwewo Handan Zitai imagwira ntchito kuchokera kutha kupereka zida zogwirira ntchito komanso zosasinthika zomwe zimathandizira zotsatira zokhazikika m'njira zambiri.
