Ubona 'i-zinc emnyama' kunye 'nozinzo' kwisivakalisi esifanayo kakhulu kule mihla. Ikwenza unqumame. Ukusuka apho ndimi khona, ndifumene kwaye ndibalule ezi zinto kuyo yonke into ukusuka kwindawo ebiyelweyo ukuya kwizibiyeli ezakhiweyo, impendulo yokwenyani ayikho kwikopi yokuthengisa. Kukwikhabhathi yesitshizi setyuwa, ixabiso lilonke lokudibanisa okungaphumelelanga, kwaye ngokungafihlisiyo, ulungiselelo lokufumana ibhetshi yokugqibezela engaguqukiyo emva kwebhetshi. Masiyinqumle i-greenwash.

Ukuzigqibezela ngokwako: Ngakumbi kunoMbala nje

Ukufakwa kwe-zinc emnyama akuyona into enye. Ngokuqhelekileyo i-zinc plating layer kunye ne-coating ye-chromate emnyama elandelayo. Leyo nxalenye 'yechromate' yiflegi ebomvu yokuqala yokuzinza kwabaninzi. Iichromethi zemveli zine-chromium enehexavalent, ingozi enkulu yendalo esingqongileyo kunye nempilo. Ishishini liye lahamba kakhulu lisiya kwi-trivalent chromates yenyathelo elimnyama, eliluphuculo oluqinisekileyo. Kodwa ‘uphuculo’ alulingani ‘luhlaza’. Iseyinkqubo ye-electrochemical enamanyathelo amaninzi ebandakanya iiasidi, iirinses, kunye namanzi amdaka afuna unyango olunzulu.

Ndikhumbula iprojekthi yeekhabhathi zonxibelelwano zonxweme. I-Spec ibiziwe I-Bolts ezimnyama ze-filec ngenxa yokunganyangeki kwe-corrosion kunye nenkangeleko ephantsi. Ibhetshi yokuqala evela kumthengisi yayibukeka igqibelele kodwa yaqala ukubonisa irust ebomvu kwi-flange serrations ngaphakathi kweenyanga ezi-6. Ukusilela? Umaleko wechromate omnyama wawubhitye kakhulu, uphantse ukuhombisa. I-angle yokuzinza yawa ngokukhawuleza-ukutshintshwa kwangaphambili kwakuthetha kabini izinto eziphathekayo, ukuthunyelwa, kunye neenyawo zabasebenzi.

Ukuqina ngundoqo kulo naliphi na ibango lozinzo lokwenene apha. Ibholithi ye-zinc emnyama ephuculwe kakuhle enomaleko otyebileyo owaneleyo we-zinc kunye ne-sealant eyomeleleyo (idla ngokuba yi-topcoat eyongezelelweyo) ingahlala iminyaka kwiindawo ezinomhlwa ophakathi. Obo bomi bude buthintela ukutshintshwa. Kodwa uthengisa iindleko zokusingqongileyo zokusetyenzwa kwangaphambili kubomi obude benkonzo. Kuyibhalansi, hayi impumelelo ecacileyo.

Ikhonkco loNikezo kunye neeNyaniso eziSebenzayo

Kulapho ithiyori idibana khona nomgangatho wefektri. Uzinzo lokwenyani kufuneka luquke iimayile zekhabhoni kwi-fastener. Kungenxa yoko le nto ukusondela kwiihabhu zokuvelisa kubalulekile. Indawo efana neSithili saseYongnian eHandan, eHebei-yeyona nto iphambili kwimveliso ye-fastener e-China. Ukuba ukhangela ukusuka apho, ucofa kwi-ecosystem egxininisiweyo. Ukusebenza kakuhle kolungiselelo olusuka kubaboneleli abadibeneyo ukuya kwizibuko elikhulu kunokuphelisa ngokubonakalayo ukukhutshwa kwezithuthi xa kuthelekiswa nokukhangela kwikhonkco lobonelelo oluthe saa.

Ndisebenze nabavelisi abasekwe apho, njengaye I-Sunnian Zitai Festener Fishaner Comment Com.. Indawo yabo, ekufuphi noololiwe abakhulu kunye nothungelwano lweendlela, ayingomgca nje kwiprofayile yenkampani (https //wwww.ziitasteners.com). Iguqulela kugcino lolungiselelo olubambekayo kunye nokuthembeka. Ngomyalelo womthamo ophezulu we I-Bolts Bolts, oko kuthembeka kuthetha ukuba awuodoli kakhulu ‘ukuba kunokwenzeka,’ unciphisa inkcitho. Ugxininiso lwabo njengomvelisi omkhulu kweso siseko luhlala luthetha ulawulo olungcono lwenkqubo kwimigca yokucwenga, enciphisa amazinga okulahlwa-olunye uhlobo lokunciphisa inkunkuma.

Kodwa nantsi i-hiccup esebenzayo: ukuhambelana kombala. I-zinc emnyama ayifani njenge-hot-dip galvanizing. Unokufumana ukwahluka ukusuka kwibhetshi ukuya kwibhetshi, ngamanye amaxesha nakwibhetshi. Kwizicelo apho i-aesthetics ibalulekile, oku kunokukhokelela ekukhatyweni. Ndibone iipallets zonke zinqabile ngenxa yokuba umbala omnyama awuhambisani nokuthunyelwa kwangaphambili. Kukusilela kozinzo-zonke ezo bholiti zisetyenzwayo ziba sisilaphu okanye zifuna ukusetyenzwa kwakhona. Sifunda ntoni? Uzinzo lokwenyani, i-spec yakho kufuneka ivumele ukwahluka kombala wendalo, okanye kuya kufuneka udibane neplateter enolawulo lwenkqubo egqibeleleyo.

Ukuthelekisa iindlela ezizezinye: Ukujonga ngokunyanisekileyo

Ngaba i-zinc emnyama sesona siphelo sizinzileyo sokumelana nomhlwa? Hayi ngokudubula okude. I-Plain mechanical galvanizing (i-zinc) ihlala ihlala ixesha elide kwaye inenkqubo elula, encinci enetyhefu, kodwa isilivere. Insimbi engagqwali (A2, A4) yomelele kakhulu kwaye inokuphinda isetyenziswe, kodwa imveliso yayo inamandla amakhulu, kwaye inokuba nenyongo. I-Hot-dip galvanizing inzima kodwa ininzi kwaye inokuphazamisana nokunyamezela.

Siye sazama ukutshintsha isixokelelwano sokuxhoma kwifama yelanga ukusuka kwi-zinc emnyama ukuya kwi-high-grade stainless. Ingxelo yozinzo ijongeka ilungile: inokuphinda isetyenziswe, ihlala ixesha elide. Ephepheni. Endle, umba wokugalela ngexesha lofakelo wawuyinto eyothusayo. Siye sasebenza kunye neetephu, sachitha iiyure zabantu, kwaye saba nokulibaziseka kokufakwa. Iindleko zekhabhoni zolo kulibaziseka kunye nokunxitywa kwezixhobo mhlawumbi azichasanga izibonelelo. Satshintshela emva kwi-premium black zinc kunye ne-topcoat ecacileyo. Yasebenza, kwaye iindleko zekhabhoni ezifakiweyo zaziphantsi.

I ukhetho oluzinzileyo ayisiyonto yokuchola eyona nto ‘iluhlaza’ kwivacuum. Imalunga nenkqubo epheleleyo: ukwenziwa, ukufakelwa, ixesha elide, kunye nokuphela kobomi. Ngamanye amaxesha, ukhetho olungagqibelelanga-ephepheni njenge-zinc emnyama lolona luzinzileyo ekusebenzeni kuba lusebenza ngokuthembekileyo okokuqala.

I-Equation Yokuphela koBomi

Akufane kuxoxwe, kodwa kubalulekile. Ekupheleni kobomi, a I-winc-idweliswe Ibholithi iseyintsimbi ehonjisiweyo enezinki ebhityileyo. Inokuphinda isetyenziswe njengentsimbi yentsimbi. Uluhlu lwe-zinc luya ku-oxidize kwi-melt. Ayifani nebholiti ene-polymer enokuthi ingcolise umjelo we-scrap. Le yingongoma ekuthandeni kwayo. Isinyithi esinzima esivela kwinkqubo yokucoca yingxaki ephezulu, ephathwayo (ngethemba) yinkqubo yokucoca inkunkuma yeplate.

Ndindwendwele indawo esebenza umbane engasebenziyo. Iimfumba zezibiyeli kunye neebholiti, ezininzi zinezinki emnyama efileyo. Zaziqwetywa nje zaza zathunyelwa kwindawo yokusila. Akukho ukuphatha okukhethekileyo. Ukusuka kumbono wezoqoqosho ojikelezayo, oko kuthe ngqo. Ubunzima, kunye nomthwalo wokusingqongileyo, wawusele uvaliwe ngexesha lokuvelisa. Oku kutyhala umbuzo wozinzo phantse ubuyele umva ngokupheleleyo kwinqanaba lemveliso.

Ke, ungayibiza ngokuzinzileyo? Kuphela ukuba umenzi unoxanduva. Kufuneka ubuze malunga nokucocwa kwamanzi amdaka, ukusebenzisa kwabo i-trivalent vs. hexavalent chromate, umthombo wabo wamandla. Umenzi kwisiseko esigxininisiweyo semizi-mveliso efana neYongnian uhlala ephantsi koqwalaselo olungqongqo lokusingqongileyo ngenxa yesikali, enokuba yinto entle. Ayigqibelelanga, kodwa yinkalo.

Isiphelo: Uzinzo olunemiqathango, olusebenzayo

Ngoko, buyela kwisihloko. Ngaba iibholiti ezimnyama ze-zinc-plated flange lukhetho oluzinzileyo? Impendulo ngu-ewe oxhomekeke, kodwa kunye ne-caveats enkulu. Ukuzinza kwabo akunto yemvelo; ixhomekeke ekusebenzeni. Ixhomekeke kwinkqubo yokucwenga esemgangathweni eqinisekisa ubomi obude, ikhonkco lokubonelela elinciphisa inkunkuma kunye neekhilomitha zekhabhoni, kunye nomenzi onoxanduva olawula iinkqubo zakhe zemichiza.

Abayi kuphumelela nawaphi na amabhaso 'obuchwephesha obuluhlaza'. Kodwa kwilizwe lokwenyani lolwakhiwo, ukuveliswa, kunye neziseko zophuhliso, apho ukusilela kuyeyona ndlela yokulahla inkunkuma, ibholithi yezinki emnyama ecaciswe ngokuthembekileyo ihlala iyeyona isebenzayo kwaye, ngokwengqiqo yobomi obugcweleyo, olona khetho luzinzileyo olukhoyo lomsebenzi. Sisixhobo, hayi indebe. Uyikhetha xa iipropati zayo ezithile-ukumelana nokubola, umthwalo we-clamp, i-aesthetics, kunye neendleko-zilungelelanisa ukuthintela iindleko ezinkulu zokusingqongileyo phantsi komgca. Olo lubizo lokwenyani lokugweba.

Ngexesha elizayo xa ubhala i-spec, jonga ngaphaya kwegama lokugqibela. Gcoba kumgangatho weplating, iingxelo zovavanyo lwemfuno, kwaye uqwalasele ukuba zenziwa phi kwaye njani. Kulapho umbuzo wozinzo uphendulwa khona, hayi kwigama lemveliso. Ukufumana umthamo, ukujonga abavelisi abadityanisiweyo kwiziseko eziphambili ezifana nale I-shoan fiitai esebenza ukusuka inokubonelela ngezo zixhobo kunye nokusebenza ngokuzinzileyo okuxhasa isiphumo esizinzileyo ngokwendlela ebanzi.
