Electro-galvanized bolts: inoenderera kune indasitiri? 

Iwe unonzwa 'electro-galvanized' uye funga 'kuonda kudzivirira,' pamwe kunyange 'girinhi' nekuti iyo zinc, handiti? Ndiko uko kunowanzotanga kukurukurirana, uye kazhinji kunopera. Asi bvunza chero munhu aifanira kudoma zvisungo zvechivakwa chekunze chinoona munyu wemugwagwa, kana chidimbu chemudziyo mudura rine hunyoro, uye kutaura chaiko kunotanga. Electro-galvanizing zvechokwadi isarudzo yakagadzikana yezvishandiso zvemaindasitiri, kana isu tiri kungobatirira kune yakajairika, yakachipa maitiro tichiregeredza mutengo wayo wehupenyu? Ndapedza makore ndichitsvaga uye ndichiyedza zvinhu izvi, uye mhinduro yacho haisi mune imwe pepa. Iri mumatanda emarara padanda mushure memwedzi gumi nemisere, mutengo wekutsiva mabhaudhi ane chiuru pane inotakura system, uye shanduko yakanyarara vamwe vatengesi vari kuita.

Kukwezva uye Chokwadi Chiripo

Ngativei zvakajeka: mabhoti e-electro-galvanized ane nzvimbo yawo. Iyo nzira yakatwasuka-zinc plating kuburikidza ne electrodeposition. Iyo inodhura-inoshanda kune yakakwirira-vhoriyamu inomhanya. Kune zvemukati, zvikumbiro zvakaoma, kana uko kupfekedzwa kuri kunyanya kutaridzika seyunifomu uye kudzivirira kwakapfava, vanoshanda. Ndakaraira matani avo kubva kunzvimbo dzakaita seYongnian District muHebei, epicenter yekugadzira fastener. Kambani kunze uko, Handan Zitai Fastener Kugadzira Co, Ltd., nehwaro hwavo kurudyi nenzira huru dzekufambisa (tarisa saiti yavo pa https://www.zitafornasteers.com kana iwe uchida pfungwa yechiyero), inogona kutenderedza izvi nekutenderera nemudziyo mutoro. Zvakanakira hazvirambiki.

Asi chekutanga chechokwadi cheki ndiko ukobvu. Iyo yakajairika electro-galvanized coating inogona kunge iri 5-8 microns. Izvo zvitete. Iwe unogona kunge wakaipfeka nemunwe kana ukaedza. Enzanisa izvozvo nekupisa-dip galvanizing, kwauri kutarisa 50+ microns, uye iyo durability mutsauko hausi mutsetse-uyo exponential. Ndakadzidza izvi pakutanga, ndichitsanangura mabhaudhi emagetsi eM12 emamwe matsigiro etirayi mufekitori ine hunyoro. Mukati memakore maviri, takanga tatova nengura chena uye imwe ngura yakatsvukuruka pamidzi yeshinda. Kwete ngwavaira, asi musoro wekuchengetedza watakanga tisina bhajeti.

Mubvunzo wekusimudzira unotanga pano chaipo: kana chigadzirwa chikatadza kukurumidza uye chichida kutsiviwa nekukurumidza, mari yekutanga yekuchengetedza (yakaderera zinc, shoma simba muplating) inokurumidza kurambwa nekugadzirwa, kutumira, uye kuiswa kwekutsiva kwayo. Iwe uri kutengesa yakaderera kumusoro kumberi kwekabhoni tsoka yeinogoneka yepamusoro yehupenyu hwese kutenderera tsoka. Ndiko kuverenga kwatisingawanzo kuita pauriri hwechitoro kana tichiisa odha.

Iyo Yakavanzwa Mari: Corrosion Performance uye Maitiro Limits

Iko electro-galvanizing inonyatsoratidza miganhu yayo mune chero nharaunda ine chlorides, acids, kana hunyoro hunoenderana. Iyo zinc yekupfekedza chibayiro, iyo yakanaka, asi yakaonda kwazvo inopera nekukurumidza. Ndinoyeuka chirongwa chinosanganisira mabhaudhi ekubatanidza kwemahombekombe ekushandisa. Takashandisa ASTM F1941 electro-galvanized fasteners, tichifunga kuti zvinenge zvakanaka. Chipfapfaidzo chemunyu chakawedzera kukoromoka, uye zingi yakanga yaenda munzvimbo mukati memwedzi, zvichitungamira mukuora kwebimetallic nesimbi yepasi. Kukundikana kwekirasi, kunodzivisika.

Imwe nyaya inowanzoregererwa ndeye hydrogen embrittlement. Iyo electroplating process inogona kuunza haidhirojeni musimbi yakasimba-yakasimba (Giredhi 8.8 uye pamusoro), ichiita kuti ive brittle uye iite nyore kutsemuka kamwe kamwe. Iyi haisi njodzi yedzidziso. Ndakaona mabhoti achiputika panguva ye-torque-up, uye apo kubheka kunogona kusunungura hydrogen, inhanho yekuwedzera inowedzera mutengo uye kuoma, uye haisi nguva dzose inoitwa zvakavimbika pamutengo wakaderera, wakakwira-vhoriyamu inomhanya. Saka, iwe unogona kutengesa corrosion dziviriro kune mechanic kutendeseka njodzi. Kwete zvakanyanya.

Ipapo pane nyaya yekupfeka uniform. Pazvikamu zvakaoma semabhaudhi ane tambo dzakadzika, iyo electrodeposition inogona kunge isina kuenzana, ichisiya mudzi weshinda-yakanyanya kunetsa pfungwa-ine kudzivirirwa kushoma. Icho chinhu chakakosha maitiro ekugumira. Iwe unogona kutsanangura chromate shanduko yejasi (yebhuruu, yero, dema oxide) yekuwedzera passivation, asi izvo zvinowedzera mamwe makemikari kune process chain. Kamwe kamwe, iyo yakapfava zinc plating haisi nyore kana kuchena.

Kuyera Green muZinc

Vatsigiri vanonongedza zinc sechinhu chechisikigo, chinogona kushandiswazve. Chokwadi. Asi iyo electroplating process pachayo haina kunaka. Mvura yetsvina inobva mumabhavhu ekuputira ine zinc ions, acids, uye mamwe makemikari. Kurapa kwakakodzera hakusi-kutaurirana kwekuteerera kwezvakatipoteredza. Mumatunhu ane akanyanya kugadzira, seYongnian, iyo yakasanganiswa manejimendi ezvakatipoteredza emazana ezvitoro zveplating ndiyo chaiyo yekusimbisa bhodhoro. Mutengesi akafanana Zitai Fastener kushanda pamwero kungangodaro kune pakati, nzvimbo dzemazuva ano dzekurapwa, asi haisi vimbiso yepasirese. Iko kusimba kwebhoti kunosungirirwa zvakananga kune kusimba kweiyo plating shopu.

Kugadziriswazve kunowedzera. Pakupera kwehupenyu, simbi inodzokororwa, uye iyo yakaonda zinc layer inorasika mukunyunguduka, asi haisi kusvibisa. Nekudaro, iyi bhenefiti yekuguma-kwehupenyu inonyanya kumanikidza kune inopisa-dip galvanized heavy metal zvikamu. Kune bhaudhi diki, iyo recycling simba tsoka yesimbi pachayo inotonga; mupiro wekuputira uri pamucheto. Iyo hombe yekusimudzira ndeyekuwedzera hupenyu hwesevhisi kunonoka chiitiko chekudzokorora kwenguva yakareba sezvinobvira.

Saka, yakasvibira here kupfuura, toti, bhaudhi-yesimbi isina tsvina? Kune nzvimbo dzakadzika-kuora, pamwe, pane yakachena kugadzirwa kwesimba hwaro (stainless steelmaking isimba-yakanyanya). Asi munzvimbo ine corrosion, bhaudhi rimwechete 304 kana 316 rinogara makore 30 rinenge rakasimba pane kutsiva mabhaudhi emagetsi makore mashanu-10 ega ega, kunyangwe nekudzokorodza. Masvomhu anochinja kana wafunga hupenyu hwakaiswa hwakazara.

Inoshanda Shifts uye Supplier Evolution

Iyo indasitiri haina kumira. Hurukuro iri kufamba kubva pakungopurwa kuenda pakuita-yakavharwa. Ndiri kuona kubvunza kwakawanda kwemechani galvanizing (iyo inodzivirira hydrogen embrittlement) kana kunyange hunyanzvi hwekuonda-firimu polymer coatings iyo inopa zvirinani corrosion resistance pane electro-zinc pahukobvu hwakafanana. Iwo akanakisa vatengesi vari kuchinjika.

Kana iwe uchitaura kune tekinoroji yekutengesa rep kune yakagadzwa mugadziri-uye ini ndakave nekutaura uku nevanhu kubva kumabasa senge Handan Zitai Fastener-havasi kungosundidzira nhamba dzekabhuku zvakare. Vanobvunza nezvezvakatipoteredza: Zviri mumba here? Chero kemikari inoputika? Coastal? Vanogona kukubvisa kubva kune yakajairwa electro-galvanized yakananga kune yakakora zinc-flake coating kana inopisa-dip sarudzo kana chako chekutanga chiri hupenyu hurefu pane yakaderera mutengo wekutanga. Icho chiratidzo chekukura. Nzvimbo yavo pachigadziko chikuru chekugadzira zvinoreva kuti vanoona kutadza kwese uye budiriro ichiyerera, uye kuti mhinduro inopinda mukurudziro yavo yechigadzirwa.

Takaedza kushandura mutengi kune Dacromet-mhando (zinc-flake) yakavharwa bhaudhi kubva kune yakajairwa electro-galvanized imwe yekushandiswa kwemidziyo yekurima. Mutengo wacho waive we15-20% yakakwira. Makore maviri mukati, mabhaudhi e-electro-galvanized pabatch yekare airatidza ngura pamisoro yehex, nepo matsva aitaridzika kunge matsva. Mutengi akarega kunyunyuta pamusoro pemutengo. Sarudzo yakagadzikana yakavachengetera mari mukufamba kwenguva nekudzivirira nguva yekudzikira yekutsiva. Ndihwo humbowo hwepasirese.

Saka, Chii Chisarudzo?

Kudaidza electro-galvanized mabhaudhi inosimudzira indasitiri yakawandisa kudai. Ndivo a situationally sustainable sarudzo. Kune inodzorwa, ine hutsinye nharaunda uko kushomeka kwekugara kwenguva refu kusingakoshese, vanopa mwero wakanaka wemutengo, kuita, uye kushandisa zviwanikwa. Kusagadzikana kwavo kunowedzerwa kana miganhu yavo chaiyo ichiremekedzwa.

Nekudaro, kune zvakajairika kushandiswa kwemaindasitiri - izvo zvinowanzoreva kushanduka humidity, condensation, kusvibiswa, kana chiitiko chemakemikari kuratidzwa-kutsamira pane yakajairwa magetsi-galvanized fasteners kazhinji hupfumi hwenhema uye nzira isina kusimba. Inosundidzira mitoro yezvakatipoteredza uye yemitengo mune ramangwana kuburikidza nekutadza nguva isati yakwana.

Iyo inogoneka nzira ndeyekufananidza tekinoroji yekuputira zvine simba kune nharaunda yebasa, kunyangwe ichidhura zvakanyanya kumberi. Zvinoreva kubvunza mibvunzo yakaoma kumutengesi wako, kutarisa kupfuura mutengo-pakirogiramu, uye uchifunga nezvemutengo wakazara wemuridzi. Iyo indasitiri ine zvirinani sarudzo ikozvino. Sustainability haisi nyaya chete; ndezvekuita sarudzo yakanaka saka chigadzirwa hachidi kuitwa zvakare chero nguva pfupi. Uye dzimwe nguva, bhaudhi rakasimba kwazvo ndiro rausingambofungi nezve kutsiva.
