Beyond Aesthetics: Iro Rechokwadi Basa reRuvara

Ngatichekei kuburikidza nemafungiro ekutanga asina kunaka: ruvara haruna kunyanya kutaridzika. Chokwadi, inobvumira mavara-coding mugungano kana kuenzanisa kwekuvaka, iyo ine kukosha. Asi mupfungwa yekushanda, iyo topcoat yeruvara-kazhinji chromate inoshandura coating nedhayi kana organic sealant-ndiro bhiza chairo. Iyo yakajairwa yakajeka kana yebhuruu-inopenya zinc plating inopa yekudzivirira ngura yekudzivirira, asi hupenyu hwayo kurwisa ngura chena, kunyanya munzvimbo dzine hunyoro kana dzemahombekombe, inogona kupfupika zvinosiririsa. Rudzi rwemavara, kazhinji gobvu trivalent kana kuti isiri-hexavalent chromate layer, inoshanda sechipinganidzo chakasimba. Inovhara porous zinc plating pasi. Ndakaona zvigetsi zvezinc zvakajairwa kubva mubatch chena corrosion mushure memaawa makumi mana nemasere muyedzo yekupfapfaidza munyu, nepo iyo yero iridescent kubva kubhechi rimwe chete ichiri kuchena pamaawa makumi mapfumbamwe nematanhatu. Musiyano hausi wekuzora; ndiko kukwidziridzwa kwakakosha mukudzivirira ngura.

Izvi zvinotungamira zvakananga kune inosimudzira angle. Kana bhaudhi richitora kaviri kana katatu kureba risati raora, uri kuderedza kutsiva frequency, tsvina yezvinhu, uye basa/simba rekugadzirisa. Ndiyo bhenefiti inobatika yehupenyu. Asi-uye ihombe asi-izvi zvinotsamira pakuvimbika kweiyo mavara ekugadzira. Kugezesa kusingadzoreki zvakanaka, nguva yekunyudza isingaenderani, kana kushambidzika zvisina kukwana kunogona kukusiya uine chikamu chinotaridzika zvakanaka pakusvika asi chinotadza nguva isati yakwana. Ruvara runogona kuvanza zvitadzo zvakawanda muzasi zinc layer, ndosaka kuvimba nemupi wako wekugadzirisa maitiro hakugone kutaurirana.

Ndinoyeuka purojekiti yemugwagwa wepamhenderekedzo yegungwa. Mugadziri wezvivakwa aida kupera kwakasviba kwebronze. We sourced mavara zinc-plated mabhoti izvo zvaienderana zvakakwana. Pakuona, vakanga vasina chavanopomerwa. Mukati memwedzi 18, takava nemishumo yokuva netsvina. Kuongororwa kwepashure-kutadza kwakaratidza kuti zinc layer yaive yakaonda uye ine zvigamba; jasi rakanaka repamusoro rakanga rangofukidza basa rekuisa pasi pasi. Chigadzirwa chakasimba, chehupenyu hurefu chakave chitubu chekutadza kusati kwasvika uye kuraswa. Chidzidzo chaive chisiri chekuti tekinoroji yakashata, asi kuti kuita kwayo kunoenderana nemaitiro.

Iyo Chemistry Shift: Kubva kuHex-Cr kuenda kune Trivalent uye Beyond

Iyo dhiraivha yekusimudzira yakanyatso shandura chemistry kuseri kwemajasi aya. Kwemakumi emakore, chiyero chegoridhe chekupikisa kwepamusoro-soro yaive hexavalent chromate (Hex-Cr) passivation layer. Yakaburitsa mapeji eyero kana iridescent uye yainyatsoshanda. Asi zvakare ine muchetura uye carcinogenic, inotungamira kune yakaomesesa kwezvakatipoteredza uye yevashandi mitemo yekuchengetedza (RoHS, REACH). Kudaidza Hex-Cr yakavharwa bhaudhi inogoneka inogona kuseka, zvisinei nehupenyu hwayo.

Iyo innovation-iyo chaiyo inoenderera nhanho-yave iri kuvandudzwa kweiyo inogoneka trivalent chromate uye isiri-chromium (semuenzaniso, zirconium-based, silica-based) kutendeuka majasi anogona kuve nemavara. Izvi zvine ngozi shoma. Kana mutengesi achida Handan Zitai Fastener Kugadzira Co, Ltd. inotaura nezve yavo yemavara zinc plating ikozvino, ivo vanenge vachireva kune aya machemistries matsva. Iri muYongnian, moyo wekuChina wekukurumidza kugadzira, vari munharaunda yaifanirwa kuchinjika nekukurumidza kumamiriro epasirese ezvakatipoteredza. Iyo shanduko haisi yekusarudzika kune vanotengesa kunze.

Nekudaro, gakava rekuita parity ndeyechokwadi. Ekutanga trivalent chromates aisaenderana neHex-Cr yekuzviporesa zvivakwa kana munyu kupfapfaidza kuramba. Tekinoroji yakabata zvakanyanya, asi inoda kunyatso kudzora maitiro. Kemikari yekugezera haina kukanganwira zvishoma. Ndakave nehunyanzvi reps kubva kumakambani emakemikari ekuputira anobvuma kuti kana iyo pH kana tembiricha ikanyura, kusimba kwemavara uye kuita kwecorrosion kwemaitiro matatu anogona kusiyana kupfuura yekare, ine muchetura mwero. Saka, iyo inogadziriswa imwe nzira inoda hunyanzvi hwepamusoro kubva kumugadziri. Haisi nyore kudonhedza-in kutsiva.

Supply Chain Realities uye Yongnian Factor

Paunoboora kupinda papi idzi mavara zinc-plated mabhoti kubva, vhoriyamu hombe inoyerera nemumasumbu akaita seYongnian District muHandan. Kuwanda kwehunyanzvi uye zvivakwa ikoko kunoshamisa.
