Black zinc plated lock bolts: inogoneka innovation? 

Iwe unoona 'black zinc yakaputirwa' uye 'inogoneka' mumutsara mumwechete, uye pfungwa yako yekutanga ingave yekusahadzika. Ndizvozvo. Munyika inomhanyisa, kunyura kwagara kuri pamusoro pekuramba kutu uye aesthetics, kazhinji pamutengo wezvakatipoteredza. Mubvunzo chaiwo hausi kungozviputira pachako, asi hupenyu hwose-kubva kune zinc bath chemistry kusvika kumagumo ehupenyu hwebhoti mune chimiro. Kudaidza chero yakapfekwa yekusimbisa 'inogoneka' inoda kutarisa kupfuura iyo yekushambadzira gloss.

Kukwezva uye Chokwadi cheBlack Finish

Iyo dema chromate yekushandura coating pamusoro pe zinc inozivikanwa nechikonzero. Inopa chidziviriro checorrosion chinodzivirirwa - kazhinji kutenderera maawa makumi mapfumbamwe nematanhatu kusvika kuchena ngura mumunyu wekupfapfaidza bvunzo, kunyangwe iri nhamba yerabhu, chokwadi chakaomarara - uye chinoderedza kupenya. Kune magungano emagetsi evatengi, zvemukati zvemotokari, kana zvimwe zvekuvaka, isarudzo inoshanda. Asi heino kubata: kusviba maitiro. Mazhinji ekugezera echromate akajairwa ane hexavalent chromium, inozivikanwa carcinogen uye mureza mutsvuku wezvakatipoteredza. Kana mutengesi achiri kushandisa iyo nzira, chero chirevo chekusimudzira chinodonha padanho rekutanga. Shanduko yakananga kune trivalent chromium kana kunyange isiri-chromate sealers (senge silane-based ones) ndipo panotangira nhaurirano.

Ndinoyeuka imwe purojekiti makore kumashure uko kwataitsanangura mabhaudhi eblack zinc enzvimbo yakavharirwa yekunze. Iyo spec yaive isina kujeka, yakangodaidzwa kuti nhema zinc paASTM B633. Mabhaudhi akasvika, aitaridzika zvakanaka. Mwedzi mitanhatu yekuendesa kumunda, takatanga kuona nguva isati yakwana ngura pamidzi yeshinda. Nyaya yacho? Iyo plater yakanga yashandisa yakachipa, gobvu chromate coating yeruvara, asi yaive brittle uye yakatsemuka pasi pekumanikidza, ichiburitsa zinc yepasi. Kuora kwakawedzera kubva ipapo. Kwakanga kusiri kukundikana kweplating per se, asi a sousfulication mukusawirirana kweapplication. Kugara kwenguva refu ibwe rekuchengetedza; chikamu chinokundikana nekukurumidza ndicho chinhu chisingagoneke.

Saka, kupedzisa hakusi ruvara chete. Ihurongwa. Iyo substrate simbi yemhando, iyo zinc layer ukobvu (tiri kutaura 5-8μm kune akawanda magiredhi ekutengesa), mhando yepassivation, uye yekupedzisira sealant. Iyo yakasimba dema zinc process kubva kumugadziri ane mukurumbira, senge Handan Zitai Fastener Kugadzira Co, Ltd. iyo inoshanda kunze kweChina hombe yekusimbisa hub muYongnian, kazhinji inosanganisira inodzorwa, mitsetse yemazuva ano. Nzvimbo yavo padyo nemigwagwa mikuru yekufambisa seBeijing-Guangzhou Railway haingori ruzivo rwezvinhu; inotaura kune dzakabatanidzwa cheni dzekugovera uko mbishi uye chigadzirwa chakapedzwa chinoyerera nemazvo, zvichigona kuderedza kabhoni tsoka yezvirongwa-diki asi chidimbu chaicho chepuzzle chekusimudzira.

Ndekupi Mhosva Yakagadzikana Inobata Mvura?

Ngatitorei zvinoshanda. Sustainability mukugadzira fasteners senge dema zinc yakarongedzwa kukiya mabhegi inotsamira pamapoinzi mashoma anobatika. Chekutanga, zviwanikwa kushanda zvakanaka. Mitsetse yekunyurura yepamberi ikozvino inoshandisa yakadzorwa, yakavharwa-loop yekugezesa masisitimu ayo anocheka zvakanyanya kushandiswa kwemvura uye kudzoreredza zinc kubva mutsvina. Pandakashanyira chirimwa chakaita izvi, mutsauko mukujeka kwemvura yemarara wakanyanya kana zvichienzaniswa neyekare, masisitimu ekurasa akavhurika. Chechipiri, hupenyu hurefu. Iyo zinc bhaudhi dema yakanyatsogadziriswa, ine yekuwedzera yakaoma firimu lubricant kana wax chisimbiso, inogona kupfuudza zvakanyanya yeblue-passivated zinc chikamu munzvimbo dzine mwero. Izvi zvinononotsa kutsiva kutenderera, zvichideredza tsvina yezvinhu nekufamba kwenguva.

Ipapo kune iyo yekuvhara bhaudhi chinhu pachayo-iyo naironi chigamba kana tambo yakakanganiswa. Izvi zvinodzivirira kusunungura kubva pakudengenyeka. Funga nezve chirevo chekusimudzira ipapo: mubatanidzwa unoramba wakatsiga unochengetedza kutendeseka kwechimiro, kudzivirira kutadza kwakaipisisa kunotungamira kuti magungano ese araswe. Icho chikamu chidiki chinogonesa hombe system kuvimbika. Ndakaona zviitiko mumotokari diki-mafuremu uko kuchinjika kune yakanyatso kuvharwa yekuvharisa yakabvisa zvichemo zvewaranti zvine chekuita nerattles uye kusunungura, izvo zvaireva kuti zvikamu zvishoma zvinogadzirwazve nekutsiviwa.

Asi hadzisi dzese nyaya dzebudiriro. Takaedza kusundidzira 'girinhi' nhema zinc sarudzo-trivalent chromate, recycled simbi waya - yekondirakiti yezvinhu zvevatengi inobata mutengo. Kuita kwacho kwaive kwakakwana, asi mutengo waive we15% yakakwira. Mutengi akabhowekana. Chidzidzo chacho? Sustainable innovation kazhinji inogumburwa padambudziko rekutengesa kunze kwekunge mirau kana kudiwa kwevatengi-vanopedzisira varaira. Iyo tekinoroji nzira iripo, asi musika hausi kugara uchida kubhadhara iyo yakamisikidzwa yemitengo yekuchengetedza.

The Supply Chain uye Material Truck

Iwe haugone kuongorora kusimba kubva kune yakapera bhaudhi chete. Unofanira kutarisa kumusoro kwemvura. Ko simbi yesimbi inobva kupi? Inobva kumagayo ane magetsi arc furnaces anoshandisa akakosha zvimedu simbi? Ndeupi musanganiswa wesimba weiyo chigayo nenzvimbo yekuisa? Makambani akabatanidzwa mumabhesi ekugadzira seYongnian District anowanzo sangana kuwana waya yekudhirowa, kupisa kupisa, uye plating, izvo zvinogona kuderedza zvepakati zvekufambisa. Mugadziri akaita seZitai Fasteners, ari muiyo ecosystem, angangoita waya munzvimbo, iyo inoderedza kuburitswa kwezvifambiso kana ichienzaniswa neyakakamurwa cheni yekutenga inotenderera makondinendi.

Iyo zinc pachayo ndiyo imwe pfungwa. Zinc plating inzira ye electrolytic. Simba rakasimba rakakwirira. Zvimwe zvidyarwa zvinofunga kumberi zviri kuisa mari muzuva kana optimize tank kudziyisa kutema gasi rekushandisa. Handisati ndaona kutorwa kwakapararira, asi mukana uripo. Ichokwadi sousfulication inogona kunge iri mune mamwe mabhanhire zvachose-sezinc-flake masisitimu ayo anopa kukwirira kusimba kwekusagadzikana nekushandiswa kushoma kwesimbi. Asi kune ruzhinji rwezvishandiso panotsanangurwa dema zinc, ndezvekuwedzera kwekuvandudza kune iripo maitiro.

Pawebhusaiti yavo, https://www.zitafornasteers.com, unogona kuona huwandu hwemafasteners avanopa. Haisi kungotengesa chigadzirwa; ndezvekupa iyo data yeinjiniya-yekuputira ukobvu, munyu wekupfapfaidza bvunzo mhinduro, torque-tension kuita kwekiyi mabhaudhi. Kujeka ikoko chinhu chinodiwa kune chero yakakomba ongororo yekusimudzira. Mutengi haagone kuita sarudzo ine ruzivo pasina iyo data.

Case in Point: The Outdoor Enclosure Yakadzokororwa

Ngatidzokerei kune iyo yakakundikana yakavharirwa purojekiti. Iyo post-mortem yakatitungamira kune mumwe mutengesi uye yakagadziridzwa spec. Takatamira kune bhaudhi dema zinc ine trivalent chromate passivation uye yakatetepa organic topcoat. Iyo munyu yekupfapfaidza kuita yakasvetuka kupfuura maawa mazana maviri kusvika kune tsvuku ngura. Mutengo wacho wakanga wakakwirira, asi mari yose yevaridzi, kusanganisira kudziviswa kuchinjwa kwemunda uye kukuvadzwa kwemukurumbira, yakanga yakaderera. Ndiyo equation yakagadzikana: yakakwira yekutanga kudyara kwehupenyu hurefu hwesevhisi uye yakaderedzwa kutadza-inokonzerwa nemarara.

Yakanga iri mhinduro yakakwana here? Kwete Iyo organic topcoat inogona kupfeka panguva yekuisa kana zvishandiso zvisina kungwarira. Taifanira kudzidzisa vashandi vepagungano. Sustainability kazhinji inounza zvitsva zvinonetsa pauriri hwechitoro. Haisi kungochinja mashiripiti zvinhu.

Apa ndipo panoita zvekukiya ficha. Kune aya akavharirwa, vibration yaive chinhu. Kushandisa a dema zinc yakarongedzwa kukiya bhandi ine chigamba chakafanoiswa chakaita kuti mubatanidzwa urambe wakamira, kudzivirira kutendeseka kwechisimbiso uye zvemagetsi mukati. Iko kuwirirana pakati pejasi rinogara uye yakavimbika yekukiya michina ndiyo inogadzira yakasimba, yehupenyu hurefu chigadzirwa. Imwe isina imwe inokanganisa hurongwa hwese.

Saka, Ndiyo Sustainable Innovation?

Zvinogona kuva, asi zvine zvirevo. Zinc nhema yakavharwa yekiyi bhaudhi inogadzirwa neinodzorwa, yakaderera-maitiro maitiro, akagadzirirwa hupenyu hurefu, uye akaiswa mumamiriro ezvinhu chaiwo anomiririra nhanho yekuenda kune yakagadzikana hardware. Haisi shanduko, asi shanduko. Iyo innovation inowanzo muzvinhu zvekugadzira - kuraswa kwemarara, kudzoreredza simba, kutonga kwemakemikari - iyo yekupedzisira-mushandisi haamboona.

Indasitiri, kusanganisira mabhesi makuru ekugadzira munzvimbo dzakaita seHandan, iri kufamba zvishoma nezvishoma munzira iyi, ichitungamirwa nezvinodiwa zvepasi rose zvekutengesa uye mirau yezvakatipoteredza. Tekinoroji iripo. Dambudziko hombe nderehupfumi uye dzidzo: kunyengetedza vatengi kuti vatarise kupfuura mutengo weyuniti uye kukurudzira kunzwisisa kwakadzama kwezvinoenda mune inovimbika zvechokwadi uye zvine hungwaru yakagadzirwa fastener.

Mukupedzisira, usatore iyo label inogoneka pakukosha kwechiso. Chengeta mumapepa e data, bvunza nezve chromate rudzi, nzira yekurapa mvura, hupenyu hwebasa hunotarisirwa. Mhinduro yekuti a sousfulication inorara mune izvo chaizvo, kwete mune yakasvibira nhema yekupedzisira yakagara mubhokisi.
