Electro-galvanized pin shaft durability? 

Kana mumwe munhu achibvunza nezve electro-galvanized pini shaft kusimba, pfungwa yangu yekutanga ndeyekujekesa: tiri kutaura nezve hupenyu hwejasi kana kuvimbika kwepini pasi pejasi iro? Kazhinji, vanhu vanoona zinc inopenya ichipera uye vanofungidzira kuti inhoo isingapindi bara. Hazvisizvo. Icho chidimbu chechibairo, uye kuti inotora nguva yakareba sei zvinoenderana zvachose nezvauri kuibayira.

Chokwadi cheZinc Layer

Ngatitorei zvakananga. Iyo yakajairika electro-galvanized coating pane kabhoni simbi pini shaft inogona kunge yakatenderedza 5-8 microns. Munzvimbo inodzorwa, yakaoma yemukati, inogona kugara kwemakore pasina dambudziko. Asi iyo nguva yaunounza hunyoro, munyu, kana kubvongodzwa kwakafanana, wachi inotanga kukwenya nekukurumidza. Ndakaona mapini pamichina yekurima munzvimbo dziri mumahombekombe achiratidza ngura chena mukati memwedzi, kwete nekuti kurira kwacho kwainge kwakaipa, asi nekuti nharaunda yaive nehukasha kupfuura zvairehwa. Mubvunzo wekusimba haubatsiri pasina mamiriro enzvimbo yebasa.

Imwe gomba rinowanzo kuvhiringa nekupisa-dip galvanizing. Electro-galvanizing yakatetepa, yakapfava, uye inopa yakanakisa corrosion kuramba kune huremu hwayo uye mutengo, asi haisi iyo inorema-basa nhumbi dzekurwa dzinopihwa kupisa-dip. Ndinoyeuka purojekiti apo mutengi akashandisa mapini ane electro-galvanized chidimbu chemidziyo yekunze yekusimbisa muviri, achitarisira hupenyu hwemakore gumi. Vakaodzwa mwoyo apo ngura tsvuku yakaonekwa pakupera kwemakore matatu. Iko kutadza kwanga kusiri muzvinhu zvepini kana maitiro ekuputira pase, asi mukusawirirana pakati pekutarisira kwekushandisa uye yekuputira yemukati mipimo.

Iko kunamatira kwezinc layer kwakakosha. Shaft isina kunyatsogadziriswa-girisi, mill scale, kana ngura yakasara-inozoguma nejasi rinoputika pasi pekunyanya kunetseka kwemagetsi. Ndinogara ndichisimbisa kukosha kwekuchenesa uye kutora matanho pamberi pekugeza zinc. Pini kubva kumutengesi ane mukurumbira akafanana Handan Zitai Fastener Kugadzira Co, Ltd. muYongnian, moyo weChina chekusimbisa chigadziko chekugadzira, unowanzo kuve nemaitiro aya pasi. Nzvimbo yavo inovapa mukana kune yakatarisana indasitiri ecosystem, zvichireva kuti mitsara yavo yekurapa isati yagara inogadzirirwa vhoriyamu uye kuenderana, izvo zvinowanzo shandura kune zvirinani substrate kugadzirira.

Pane Pini Pachezvayo Inokosha

Durability haisi kudzika ganda chete. Iyo substrate simbi giredhi ndizvo zvese. An Electro-Gallvized Pin Shaft yakagadzirwa kubva pasi-kabhoni simbi yakafanana neQ235 (A36 yakaenzana) ichakotama kana kugera pasi pemutoro nguva refu isati yapera. Kune mapoinzi epivot epamusoro-soro, iwe unofanirwa kutarisa masimbi epakati-kabhoni kana alloy, senge 45 kana 40Cr, yakagadziriswa kupisa kusvika pakuoma chaiko. Iyo galvanizing process pachayo, inosanganisira kucheneswa kweasidhi uye electrolysis, dzimwe nguva inogona kutungamira kune hydrogen embrittlement mumasimbi akasimba-akasimba kana isina kunyatsogadziriswa post-plating nemushonga wekubheka.

Ndinorangarira ndichiyedza batch yemapini ye hydraulic cylinder application. Dzakanga dzakaiswa marata zvakaisvonaka, asi pasi pokuremerwa, dzairatidza kuputsika. Chikonzero chikuru? Mugadziri akasvetuka kubheka kwe dehydrogenation mushure mekuputira kuchengetedza nguva uye mutengo. Iyo zinc yaive yakakwana, asi iyo core yakakanganiswa. Ichi chinhu chakakosha nuance: iyo electroplating process inogona kukanganisa base base simbi zvivakwa. Iwe unofanirwa kubva kune mugadziri anonzwisisa yakazara ketani, kwete chete tangi yekuisa.

Pamashandisirwo emaindasitiri akajairwa, musanganiswa wepini yesimbi makumi mana neshanu, yakadzimwa uye yakapfava kusvika pakuoma kweHRC 28-35, uyezve electro-galvanized, ibasa guru. Inopa kuenzana kwakanaka kwesimba, kupfeka kuramba, uye kudzivirira ngura kumagungano asingagare akanyorova kana kuputika. Unogona kuwana aya mafungidziro sezvipimo zvakajairwa kubva kune vakawanda vakasanganiswa vagadziri mudunhu reYongnian, uko makambani akaita seZitai Fastener anoshanda neiyo yakakosha ruzivo rwakamira.

Kukundikana uye Zvakaonekwa Munda

Hapana chinodzidzisa sekukundikana. Takamboita kuti chigubhu chepini chasvika chine mapepa akakwana, asi pakuungana, shinda (idzo dzakanga dzakaputirwawo) dzairwadza. Nyaya yacho? Iyo electro-galvanized coating ukobvu pane shinda yakanga isingadzoreki zvakaringana, ichichinja kukwana uye kukonzera kukanganisa. Kwakanga kusiri kutadza kusimba mupfungwa yekuora, asi inoshanda yakakonzerwa nekupfeka. Isu taifanira kuchinjira kumutengesi akapa yakasarudzika masking yeshinda kana post-plating kudzvanya zvakare.

Imwe classic ndeye crevice corrosion. Iwe unogona kuve nepini ine zvinoyevedza, asi kana ikadzvanywa mugomba risingaoni kana kubatanidzwa nesimbi yakasiyana sealuminium pasina kuparadzaniswa kwakakodzera, unogadzira musungo wakakwana wekunyorova. Iyo zinc inozvipira pachayo, asi munzvimbo iyoyo yakavharirwa, haigone kumisa kukurumidza kurwisa. Ndakavhomora mapini aitaridzika zvakanaka pashank yakashama asi aive akaora zvakanyanya uye akabatwa mamilimita mashoma mukati meimba. Tinodzidzei? Sistimu dhizaini chikamu chepini yekusimba equation.

Abrading nzvimbo ndiyo bvunzo yechokwadi. Mukubatanidza masisitimu anogara achitenderera, zinc layer pane yakapfekwa inopera nekukasira, ichisiya simbi isina chinhu ichibuda pachena. Muzviitiko izvi, kutsanangura kurapwa kwakaoma kwepamusoro, senge chrome plating panzvimbo dzinotakura, kana kusarudza pini-yakaomeswa uye kubvuma kuti inozoita ngura painopfeka (iyo inowanzogamuchirwa kana simba rikachengetwa), inzira inoshanda kupfuura kuvimba nekugadzika kwega.

Basa reMutengesi uye Inoshanda Sourcing

Izvi zvinondisvitsa pakutsvaga. Paunoda akavimbika Electro-Gallvized Pin Shaft, hausi kungotenga chigadzirwa; uri kutenga mugadziri maitiro ekugadzirisa. Nzvimbo yekambani uye maindasitiri mamiriro ezvinhu. Handan Zitai Fastener Kugadzira Co, Ltd., iri muDunhu reYongnian ine zvivakwa zvaro zvakaomesesa, zvinobatsira kubva kunzvimbo dzekugovera cheni dzetsvimbo dzewaya, makemikari ekuputira, uye masevhisi ekurapa kupisa. Izvi zvinowanzoreva zvirinani kudzora mutengo uye nekukurumidza kutendeuka kwezvinhu zvakajairika. Kusvika kwavo kunzira huru dzekufambisa seBeijing-Guangzhou Railway uye G4 Expressway, sezvakacherechedzwa pawebhusaiti yavo. https://www.zitafornasteers.com, haisi bhonasi yekutakura chete; inoratidza kuti dzakaiswa mumusika wepamusoro-soro, wemakwikwi anoda kushanda zvakanaka.

Paunenge uchiongorora mutengesi, ini handingo kumbira pepa rakatsanangurwa. Ini ndinobvunza nezve yavo post-plating kurapwa kwekuyamura hydrogen. Ini ndinokumbira mushumo wekupfapfaidza munyu chaiwo kune batch, ndichivavarira kweashoma maawa makumi mapfumbamwe nematanhatu kusvika kuchena ngura yenzvimbo dzakajairwa. Ndinogona kutokumbira sampuli kuti ndiite bvunzo yakapfava yekunamira-kunamatidza iyo nebanga uye kuisa tepi kuti ndione kana ichisimudzwa. Aya ndiwo macheki anoshanda anoparadzanisa mutengesi wekatalogi kubva kune ane ruzivo mudiwa.

Kune tsika kana yakakosha maapplication, kutaurirana kwakananga kwakakosha. Kutsanangura iyo chaiyo nharaunda yekushanda - cyclic kurodha, kungangoita kemikari kuratidzwa, tembiricha yemhando - inobvumira hunyanzvi fekitori seZitai kukurudzira kugadzirisa. Zvichida iine zingi rakakora zvishoma, kurapa kwakasiyana kwechromate (yebhuruu, yero, kana dema) kwemaawa ekuwedzera ekuramba kwecorrosion, kana shanduko mune yekutanga zvinhu. Basa ravo senyanzvi yekugadzira ndere kushandura durability yako yaunoda kuita maparameter.

Mafungiro Ekupedzisira - Ihurongwa

Saka, dzokera kumubvunzo wekutanga: Imhinduro ine zvirevo. Iyo yekuputira inopa yakanakisa, inodhura-inoshanda kuchengetedzwa kweakasiyana maapplication, asi haisi mhinduro yepasirese. Upenyu hwayo ibasa rekupfekedza ukobvu, kugadzirira substrate, kuomarara kwezvakatipoteredza, uye kupfeka kwemuchina.

Pini yakasimba kwazvo ndiyo yakanyatsotsanangurwa basa rayo. Dzimwe nguva, izvo zvinoreva kubvuma kuti electro-galvanizing ndeyekushongedza kana kureruka-basa rekudzivirira kupera, uye nemamiriro ezvinhu akaomarara, unofanirwa kukwira kusvika pakupisa-dip, mechanical plating, kana zvimwe zvinhu zvakaita sesimbi isina tsvina. Chinokosha ndechekupfuura fungidziro yekuti galvanized is a single, high-performance category.

Pakupedzisira, zvinosvika pakuongorora kwakatendeseka uye kutaurirana kwakajeka pakati pemugadziri uye mugadziri. Kushandisa hunyanzvi hwevagadziri vane hunyanzvi mumahubs seYongnian vanogona kubhuroka iro gaka, kushandura chinhu chiri nyore chechinhu kuita chinhu chakavimbika, chinogara kwenguva refu. Iwe unogona kuwana zvakawanda pane zvavanogona pane yavo saiti, zitafasteners.com, asi rangarira, iyo yekupedzisira inofanirwa kunge iri hurukuro, kwete kungodzvanya.
