Iwe unoona uyu mubvunzo uchibuda mune specs uye RFQs nguva dzese. Mhinduro pfupi, inoyedza kazhinji hongu, yakavharwa zinc, yakanaka. Asi kana wanga uri pa-saiti uchiona zera rechimiro, kana zvakanyanya, uchibata nekufona kumashure pane yakundikana kubatana, unoziva kuti hazviwanzo nyore kudaro. Mhinduro chaiyo inogara muruzivo rwezvakatipoteredza, kunaka kweplating, uye kutaura chokwadi, zvinorevei zvinorevesa kuupenyu hwepurojekiti maringe nekungove izwi rekugezesa girini. Ngatikurukurei izvozvo.

Iko Kukwezva uye Chokwadi cheZinc Layer

Electro-galvanizing inokwezva nechikonzero. Iyo inowanzo kudhura-inoshanda pane inopisa-dip galvanizing uye inopa yakachena, yakatsetseka kupera inotaridzika zvakanaka kunze kwebhokisi. Maitiro acho anosanganisira electroplating chidimbu chezinc pane chigadziko chesimbi. Iyo kiyi metric inokandwa nemunhu wese kutenderedza iko kukobvu, kazhinji ichivavarira kutenderedza 5-8 mamicrons emabhaudhi akajairwa emagetsi. Iyi layer inopa kudzivirirwa kwezvipingamupinyi. Inodzivirira simbi kubva kune unyoro nemhepo.

Asi heino yekutanga inoshanda hiccup: iyo layer itete. Uye haina metallurgically yakasungirirwa senge mukupisa-dip. Ndakaona mabheti uko kupfekedzwa kwanga kusina kuenzana, kunyanya mushinda uye pasi pemusoro-idzo nzvimbo chaidzo dzinonyanya kushushikana. Mutengesi anogona kudaidzira kuenderana neASTM B633, toti, SC Type 2, asi pasina kuenderana maitiro ekutonga, iwe unowana isina kusimba mavara. Kambani yakadai Handan Zitai Fastener Kugadzira Co, Ltd., yakavakirwa muChina's hombe fastener yekugadzira hub muYongnian, Hebei, inogona kuve nekwaniso yekumhanya kukuru, asi basa riri pamutengi kuti aone kuenderana kwemhando yezvinhu zvebasa rekunze, kwete kungozvifunga.

Saka, yebindu rakadururwa munzvimbo yakaoma? Pamwe zvakanaka kwemakore. Kune yemahombekombe vharanda railing, bhiriji rekuwedzera munzvimbo inonaya, kana chero chimiro chinogara nyoro-yakaoma kutenderera? Chidziviso chitete ichocho, chinogona kunge chisina kukwana chinova chinongedzo chisina kusimba. Chirevo chekusimudzira chinotanga kutsemuka kana chigadzirwa chichida kutsiviwa mumakore mashanu.

Corrosion Mechanisms: Haisi Ngura chete

Vanhu vanofunga kunze uye vanofungidzira yunifomu ngura. Chokwadi chakanyanya kugariswa uye chakashata. Mhondi mbiri huru dzemagetsi-galvanized fasteners panze iwhite rust uye galvanic corrosion.

Ngura chena ndiyo dhipoziti chena yaunoona pazinc. Izvo zvinoitika apo zinc coating inogara yakanyorova uye haigone kuumba yayo yakagadzikana inodzivirira patina (zinc carbonate). Munzvimbo dzakadzivirirwa dzekunze uko mvura inogara-sepakati penzvimbo dzakasungwa kana mumakomba asina kucheneswa - zinc inoora nekuzvipira uye nekukurumidza. Ndakabvisa kubatanidza mushure memwaka miviri kuti ndiwane zinc inonyanya kushandurwa kuita hupfu chena, ichisiya simbi inenge isina.

Galvanic corrosion ndiyo mhondi yakanyarara. Patanidza electro-galvanized simbi bhaudhi ine aruminiyamu kuumba, kana zvakanyanya, mhangura kana simbi isina tsvina, pamberi pe electrolyte (mvura inonaya yakakwana), uye iwe unogadzira bhatiri. Iyo zinc, ichiwedzera anodic, inoora nekukurumidza kuchengetedza imwe simbi. Ndinoyeuka imwe purojekiti tichishandisa Electro-Gallvized Bolts kuchengetedza mhangura inopenya trim. Iyo spec yakamhanyiswa. Mukati memwedzi ye18, misoro yebhaudhi yakaparadzwa zvakanyanya, zvichikanganisa kugadzirisa. Kugadzirisa kwaive kwakazara, kunodhura kutsiva ne insulated Stainless simbi. Mari yekutanga yakabviswa.

Coating Kutendeseka uye Dambudziko re Thread

Chinhu chakanyanya kurwadza ishinda. Iyo electroplating process inogona kusiya brittle, yakakwirira-yekuvaka coating pane shinda crests. Panguva yekuisa, iyi yekupfeka inogona chip kana kuputika. Iye zvino wave nestress riser ine zero corrosion protection. Takatanga kutsanangura chromate conversion coatings (yero iridite kana yakajeka bhuruu) pamabhaudhi e-electro-galvanized kuti awedzere dziviriro, asi kunyangwe icho chingori chigadziko chepasi pane zinc, kwete gadziriso yekukuvara kwemuchina. Kudonhedza pasi bhaudhi kunogona kuikweva pairi nati kana buri rakapombwa.

Case in Point: Iyo Yakaderera-Mutengo Fence Project

Muenzaniso wekongiri kubva makore mashoma kumashure. Paki yemanisipala yaida kuisa mazana emamita efenzi yesimbi yetubula. Budget yaive yakaoma. Iyo spec yaida mabhaudhi ane galvanized. Kondirakiti, ichivavarira kubhadharisa yakaderera, yakachipa emagetsi-galvanized mabhaudhi, angangoita kubva kumugadziri mukuru. Vairatidza kupenya pakuisa.

Kurumidza mberi makore matatu, munzvimbo ine mwero maindasitiri mamiriro uye nzira munyu pfapfaidzo munguva yechando. Mafuremu efenzi aive akanaka (hot-dip galvanized), asi bhaudhi rese remusoro nenzungu raive dhaka retsvina tsvuku uye chena. Kuora kwacho kwainge kwakashata zvekuti dzimwe nzungu dzakabatwa, zvaida kuti ma angle grinders abviswe panguva yekudzorera. Mamiriro ekuchengetedza aive zero-kurasa kukuru kwevashandi uye zvinhu zvekugadzirisa nguva isati yakwana. Dai iyo fungidziro yakanyatsodaidzira kuti hot-dip galvanized (HDG) zvisungo kuti ienderane nejira refenzi, kana kunyange zvirinani, galvanizing yemagetsi yekupfekedzwa kweshinda, hupenyu hungadai hwakapetwa kaviri kana katatu.

Apa ndipo panodiwa ruzivo rwekutsvaga. Nzvimbo yemugadziri, sekunge Zitai Fastener iri padhuze nemigwagwa mikuru yekufambisa (Beijing-Guangzhou Railway, Expressway), inotaura nezvekugona kwezvinhu, kwete kukodzera kwechigadzirwa. Iwe unofanirwa kuchera mune yavo chaiyo maitiro ekudzora ekunze-giredhi electro-galvanizing, kana ivo vakatopa iyo seyakatsaurirwa chigadzirwa mutsara.

Apo Electro-Galvanized Workout Outdoor?

Hakusi kuparara kwese uye kusuruvara. Kune niches. Kudanwa kwekutonga kunouya pasi pekuoma kwezvakatipoteredza uye kuwanikwa kwekugadzirisa.

Zvemukati kana zvakachengetedzwa zvekunze zvikumbiro (senge mukati memhepo inofefetera padenga truss system yakachengetedzwa kubva kune yakananga mamiriro ekunze), electro-galvanized yakakwana zvakakwana. Kudzivirirwa kwayo necorrosion inokwana pamhepo yemhepo chete.

Chimwe chiitiko ndechenguva dzekunze zvivakwa zvakagadzirirwa disassembly uye kushandiswazve mukati menguva pfupi, toti makore 1-3. Kupera kwakatsetseka kunoita kuti kubata kuve nyore. Zvakare, kana iyo yekusungira ichizozopendiwa kana upfu-yakaputirwa sechikamu chegungano, iyo electro-galvanized layer inopa yakanaka, yakachena kiyi yependi system uye inowedzera imwezve dhizaini yekudzivirira. Asi hurongwa hwepende hunofanira kunge hwakasimba uye huchishandiswa nemazvo - zvikwambo panguva yekuisa kana sevhisi zvinogadzira nzvimbo dzakanangana nekuora.

Mutongo: Sustainable iBasa reLifecycle

Saka, kudzokera kumubvunzo mukuru. Mabhaudhi e-electro-galvanized akasimba kushandiswa kwekunze? Kutora kwangu, kubva mukurwisana nesarudzo iyi kakawanda, ndeichi: vanogona kuva, asi chete pasi pemamiriro ezvinhu akamanikana ayo asingawanzo kusangana mune generic zvekunze zvakatemwa.

Kusagadzikana kwechokwadi kunoreva kusarudza chinhu chakakodzera chehupenyu hunotarisirwa hwesevhisi uye nharaunda kudzivirira kukundikana nekukurumidza uye kutsiva. Kune akawanda anodiwa ekunze maapplication — kumahombekombe, kunyorova kwepamusoro, maindasitiri, de-icing munyu kuratidzwa, kana zvimiro zvekusingaperi-yakajairwa electro-galvanized fasteners isarudzo ine njodzi. Idzo sarudzo dzakasimba ndedzokupisa-dip galvanized, mechanically galvanized, kana stainless simbi (se304 kana 316, zvichienderana nekubuda kwechloride). Mutengo wavo wepamusoro wepamberi unoderedzwa pamusoro pehupenyu hwakareba, hwekuchengetedza-yemahara.

Pfungwa yekupedzisira: nguva dzose tsanangura nemazvo. Usangonyora galvanized. Rondedzera maitiro (semuenzaniso, ASTM A153 yekupisa-dip), ukobvu hwekuputira, uye chero mishonga yekuwedzera. Uye kune majoini akakosha, funga pane-saiti kuongororwa kwekutanga batch yezvitsigiro. Yekukurumidza munyu yekupfapfaidza bvunzo paASTM B117, kunyangwe ingori 96-awa cheki, inogona kuratidza zvakawanda nezve mhando yemutengesi maringe nekabhuku kanoti. Iyo inoponesa nyika yemusoro gare gare, ichishandura iyo theoretical inosimudzira kudai kuita inoshanda, pamusoro-pasi chokwadi.
