Iwe unoona iri temu richitenderera mune specs uye ekutenga mapepa kakawanda ikozvino. 'Sustainable innovation' yakanamirwa kune chimwe chinhu chakakosha seye electroplated galvanized nut. Inoita kuti umbomira. Kungori kushambadzira, kana kuti pane shanduko chaiyo mukuita? Kubva pabhenji rangu, kusimba mumafasteners kunowanzo kusanzwisiswa. Haisi chete nezve zinc pashinda; iri pamusoro pecheni yese-kubva pakugezesa asidhi isati yaiswa kumvura yakasviba mushure, uye kuti nzungu iyoyo inogara kwenguva yakareba zvakakwana mumunda kururamisa kugadzirwa kwayo. Vazhinji vanofungidzira kuti electroplating ndiyo 'yakasvibira' sarudzo nekuti yakajairika uye yakaderera-yakawanda sosi pane inopisa-dip, asi ndiko kutora kwepamusoro. Iyo chaiyo nyaya ndeye messier, inosanganisira chemistry, simba spikes, uye zvimwe zvakaoma zvinokanganisa.

Iyo Plating Maitirwo: Kunogara Mubvunzo Wekusimba Chaizvoizvo

Ngatipindei mutangi, sekutaura. Yakajairika zinc electroplating line yenzungu inosanganisira nhevedzano yekugezera: kuchenesa, pickling, plating, chromating (yeiyo yebhuruu-inopenya kana yero iridescent kupera), uye pakupedzisira kugeza. Iyo gakava rekusimudzira rinorova zvakanyanya padanho rekunhonga, iro rinoshandisa hydrochloric kana sulfuric acid kubvisa ngura nechikero. Izvi zvinogadzira asidhi yakapedzwa, rwizi rwemarara ine ngozi. Ihwo hutsva hausi mukuputira pachayo-iyo tekinoroji yemakore zana-asi mumabatiro aunoita aya ekuwedzera maitiro. Yakavharwa-loop rinse masisitimu, semuenzaniso, anogona kuderedza kushandiswa kwemvura kusvika 90%. Ndakaona zvidyarwa kwavakaita evaporative kudzoreredza yekugezesa yekugezesa, kudhonza zinc uye asidhi kumashure mumhinduro. Iyo inoshamisa engineering, asi ine mari-yakanyanya. Iyo ROI inoyerwa mumakore, kwete kota, inova yakaoma kutengesa kune zvitoro zvakawanda inotariswa pamatenda matete pazvidimbu churu.

Zvadaro pane chromate yekushandura coating. Iri ndiro danho rinopa chaiyo corrosion resistance, kuumba jira pamusoro pe zinc. Iyo yechinyakare hexavalent chromium passivate injodzi huru yezvakatipoteredza uye hutano. Shanduko yakananga kune trivalent chromium kana kunyange nyowani, chromium-isina passivations ichokwadi inoenderera innovation. Asi kuita parity ichiri hondo. Ndinoyeuka batch renzungu dzakabatwa neproprietary chromium-free passivate kubva kumutengesi wekuEurope yekushandiswa kwemahombekombe. Maawa emunyu wekupfapfaidza munyu aitaridzika zvakanaka pabepa, asi mishumo yemunda mushure memwedzi gumi nemisere yakaratidza nguva isati yakwana ngura. Taifanira kuvadhonza. Hutsva hwaivepo, asi chokwadi chepasirese chaive chisipo. Yakandidzidzisa kuti 'inogoneka' haigone kuuya nemubhadharo wekutadza kushanda, kunyanya mumashandisirwo ezvimiro.

Kushandiswa kwesimba ndicho chimwe chinhu chinyararire. Electroplating inzira ye electrolytic, inomhanya yakananga ikozvino kuburikidza nemhinduro. Vanogadzirisa vane nzara yemagetsi. Ndanga ndiri munzvimbo dzavakachinjira kune yakakwirira-inoshanda rectifiers uye pulse-reverse plating, iyo inogona kuisa zinc zvakanyanya zvakaenzana nesimba shoma uye marara. Idanho rakasimba. Asi kana iwo magetsi achiuya kubva kune marasha-akabatidzwa gidhi, iyo yakazara kabhoni tsoka tsoka kuverenga inove yakasviba. Iwe unogona kuve neiyo yepamusoro-soro, zero-discharge plating mutsara, asi kana ichifambiswa nesimba rakasviba, iyo 'inogoneka' label inonzwa isina kukwana. Apa ndipo pakakosha nzvimbo. Mugadziri anogara munharaunda ine yakachena simba musanganiswa, kana imwe inodyara pane-saiti solar, inotanga neiyo irinani yekutanga.

Zvishandiso uye Hurefu Hweupenyu: Iyo Yakafuratira Metric

Durability ndiyo ibwe repakona rekusimudzira kune chero hardware. Nzungu inoora uye inotadza mumakore mashanu, ichida kutsiviwa uye nekudaro kugadzirwa kwakawanda, haigoneki, zvisinei nekuti kugadzirwa kwayo kwaive kwakachena sei. Apa ndipo panowanikwa sarudzo pakati pe electroplated ne mechanical galvanizing (sekuspin galvanizing). Electroplating inopa yakatetepa, yakawedzera yunifomu coating, yakakura kune chaiyo tambo uye aesthetic zvikamu. Asi kune inorema-basa, yakakwirira-corrosion nharaunda, iyo yakaonda layer inogona kuve mutoro. Ndakatsanangura inopisa-dip galvanized yekutapurirana shongwe nzungu kunyangwe yakakora, isina kukwana coating nekuti kudzivirira kwechibairo kunongotora nguva yakareba. Iyo 'innovation' ye electroplating pano inogona kunge iri mumhando yepamusoro alloy coatings-zinc-nickel, zinc-cobalt. Izvi zvinopa phenomenal corrosion resistance ine thinner deposits. Takaedza zinc-nickel yakapfava nzungu kubva kumutengesi wekuJapan, uye mibairo yekupfapfaidza munyu yakanga ichisundira maawa 1000 kusvika kumarara tsvuku, ichikwikwidzana nemamwe anopisa-dip specs. Kubata? Mutengo. Iyo nickel yekuwedzera uye yakanyanya kuoma yekugezesa kutonga inogona kaviri mutengo.

Imwe kona ndiyo nut substrate pachayo. Inonzwika seyakakosha, asi kushandisa inowirirana, yepamusoro-yemhando yakaderera-kabhoni simbi waya tsvimbo inoita mutsauko wenyika. Yakashata substrate inotungamira kune hydrogen embrittlement njodzi panguva yekunhonga asidhi, izvo zvinozoda kubikwa kwekuzorodza - imwe mari yesimba. Mutengesi ane kudzora kwakasimba pamusoro pezvinhu zvayo zvakasvibirira, senge Handan Zitai Fastener Kugadzira Co, Ltd., iyo inoshanda muChina yakakura yefastener yekugadzira base, ine mukana wekuzvarwa. Kuswedera kwavo kune zvigayo zvesimbi uye kugadzirwa kwakabatanidzwa kubva pawaya kudhirowa kusvika pakurongedza (https://www.zitafornasteers.com) inobvumira kuteedzera kuri nani uye kuenderana kwemhando. Uku hakusi hunyanzvi hwekugadzira, asi ihwaro hwekubuda kwakasimba: kuita kuti ive chaiyo kekutanga, kuderedza kurambwa uye kugadzirisa zvakare.

Ipapo kune kufunga kwekupedzisira-kwehupenyu, uko kune chero munhu mukutenga kwedu kwezuva nezuva kutaura nezvazvo. Electroplated zinc haina kunaka.
