Amashanyarazi ya gaze yamashanyarazi: guhanga udushya? 

Reka tuvugishe ukuri, iyo abantu benshi bumvise 'amashanyarazi ya galvanised gasketi', kuramba ntabwo aricyo kintu cya mbere gisimbuka mubitekerezo. Ihuriro ryihuse mubisanzwe ni zinc, kurwanya ruswa, wenda gato ya pasitoro ya chromate, hamwe no kumva ko ari ibintu bisanzwe, bimwe mubikorwa byinganda-shuri. Nicaye mu nama aho amakipe atanga amasoko atondagura agasanduku 'galvanised' nibwira ko ari 'icyatsi' gusa kubera ko atari kadmium, ibyo bikaba ari ibintu byoroshye. Ikibazo nyacyo cyo kuramba muriyi niche kirangaye cyane, kijyanye na chimie yimikorere, imigezi yimyanda, kuramba kuramba, nicyo dushaka kuvuga mubyukuri 'guhanga udushya' murwego rukora inganda zikuze.

Kwubaka 'Icyatsi' muri Zinc Plating

None, niki gituma gasike 'iramba'? Byerekeranye gusa nibikoresho? Niba tureba gusa ibicuruzwa byanyuma - a amashanyarazi yamashanyarazi- biroroshye gusaba inyungu. Zinc ni nyinshi, igifuniko kirinda ibyuma byangirika, byongerera ubuzima inteko yihuta. Iyo niyo ntsinzi yo gukoresha neza umutungo, sibyo? Ariko ibyo ni kimwe cya kabiri cyinkuru, igice kireba abakiriya. Igiciro cyibidukikije kiremerewe imbere mu iduka.

Acide gakondo ya chloride cyangwa alkaline itari cyanide zinc plaque twakoresheje mumyaka mirongo ni ubwogero bwimiti. Bakoresha amashanyarazi, bakeneye kwezwa buri gihe, kandi bakabyara imyanda - imyanda ishobora guteza zinc, fer, nibindi byuma. Intambwe ya passivation, yaba ubururu bwerurutse, umuhondo iridescent, cyangwa umukara, akenshi bikubiyemo ubundi buryo bwa chromium butandukanye, ariko na chromates ntoya hamwe nabashitsi bashya bashya bazana imitwe yabo bwite. Kwita ibicuruzwa byanyuma 'birambye' utabariyemo ibi, uko mbibona, imipaka yicyatsi kibisi. Ndibuka kugenzura abaguzi mumyaka yashize gutunganya amazi mabi yatekerejweho; gaseke yaka yasohotse kurundi ruhande yasaga neza ku mpapuro, ariko ibidukikije byaho byishyuraga igiciro.

Aho mbona impinduka, udushya twukuri, iri muri sisitemu zifunze kandi zitunganya chimiya. Bimwe mubikorwa byo gutekereza imbere, cyane cyane mukarere kagenzuwe, bashora imari muri sisitemu yo kuyungurura no guhanahana ion kugirango bakure zinc mumazi meza, bigabanya cyane kugura ibikoresho fatizo hamwe nuburozi bwangiza. Ibi ntabwo ari igitsina, ni ibikorwa remezo byibanda cyane, ariko niho hakorerwa inyungu zifatika zirambye. Ihindura umurongo wa plaque uhereye kumurongo ugereranya 'gufata-gukora-imyanda' mubintu byegereye uruziga, byibuze kubyuma byibanze.

Kuramba kuramba hamwe nukuri-kwisi

Aha niho ibitekerezo bihurira. Impaka zirambye zishingiye cyane kuramba kubicuruzwa. A. gasketi ibyo bimara igihe kinini bigabanya inshuro zo gusimburwa, kubungabunga igihe, no gukoresha ibikoresho muri rusange. Byumvikane neza. Ariko amashanyarazi arambuye kuramba biterwa rwose no gusaba. Ujugunye mu nyanja yumunyu mwinshi cyangwa imiti ihora ihindagurika, kandi icyo ginike cyoroshye (mubisanzwe microne 5-15 kuri gasketi isanzwe) izitanga vuba. Ni igifuniko gishobora gukoreshwa.

Ibi twabyize inzira igoye kumurongo wibihuza bya sisitemu yubuhinzi bwo hanze. Spec'd isanzwe yumuhondo zinc gasets yo kurinda ruswa. Basaga neza nuwahoze ari uruganda. Mu mezi 18, raporo zerekana ingese no kunanirwa kashe zatangiye gukemuka. Ikibazo? Amazi yaho yari afite imyunyu ngugu nyinshi n’ifumbire isigaye, ikora isupu yoroheje, isupu ikora neza yariye muri passivation na zinc ku kigero giteye ubwoba. Guhitamo kwacu 'kuramba' kwatumye gahunda yuzuye yo kongera gushakisha no gusimbuza-net mbi muburyo bwo gukoresha umutungo. Guhanga udushya ntihariho igifuniko gishya, ahubwo ni isomo ribabaza muburyo bwihariye bwo gusaba. Rimwe na rimwe, umubyimba mwinshi ushyushye ushyizwe hamwe cyangwa ibintu bitandukanye kuri bariyeri rwose ni amahitamo arambye, kabone niyo umusaruro wambere watangiriye hejuru.

Ibi biganisha ku ngingo ikomeye, akenshi yirengagizwa: kuramba birimo ibisobanuro bikwiye. An amashanyarazi yamashanyarazi ni igisubizo cyiza, cyigiciro cyinshi kubidukikije bigenzurwa murugo, muri rusange ikirere gihumeka, cyangwa nkibanze kugirango ukomeze gushyirwaho ikimenyetso. Udushya twarwo dushobora kuba muburyo busobanutse - uburebure buhoraho buturutse ku ruganda ruzwi bituma ubuzima bwateganijwe, bikarinda gukora inganda n’imyanda. Nabonye amaduka aho umubyimba wububiko watandukanijwe na +/- 50% murwego rumwe, kunanirwa kugenzura ubuziranenge byangiza byimazeyo icyifuzo cyose kirambye.

Gutanga Urunigi n'umusaruro waho: Ikintu kitavuzwe

Ntidukunze kuvuga ibijyanye na logistique mubiganiro biramba kubyerekeye ibice bito, ariko tugomba. Ikirenge cya karubone cyo kohereza kontineri ya gasketi kuva kumugabane umwe ujya kuwundi irashobora kwizirika ku bicuruzwa ubwabyo. Aha niho hubatswe inganda zikora zerekana imbaraga zabo.

Fata ahantu nk'akarere ka Yongnian mu mujyi wa Handan, Hebei. Nibikorwa binini binini byibanze mubushinwa. Isosiyete nka Hamagara zitai yihuta ukora co., Ltd. gukorera hariya, byegeranye na gari ya moshi nini na gari ya moshi, bikubiyemo ubundi buryo bwo gukora neza. Ku masoko yo muri Aziya no ku masoko menshi yo ku isi, biva muri iryo huriro bihujwe bisobanura kugabanya amaguru yo gutwara abantu, ibicuruzwa byoherejwe hamwe, hamwe n’ibicuruzwa byimbitse kandi byitabirwa. Urashobora kubona portfolio yabo kuri https://www.zitaifacens.com. Iyo zitanze amashanyarazi yamashanyarazi, inguni iramba ntabwo iri mubigega byabo gusa (nubwo aribyo byingenzi), ariko mubyukuri ko ibyuma bibisi, gushushanya insinga, gukonjesha imbeho, isahani, hamwe nugupakira bikunze kugaragara mubidukikije byangiza inganda. Ibi bigabanya ubwikorezi buciriritse, bigabanya imitwaro yo kubara (hamwe n imyanda ijyanye nubusaza), kandi itanga uburyo bwihuse bushingiye kubisabwa.

Simvuze ko ihuriro ryaho ryose ritunganye-kubahiriza amabwiriza yo kubungabunga ibidukikije biratandukanye, kandi ibyo ni caveat nini-ariko icyitegererezo ubwacyo kigabanya imyanda muburyo bwigihe, lisansi, nububiko burenze. Igipapuro cyakozwe neza kandi cyoherejwe byibuze kuva ahantu nka Handan kugeza kubaguzi bo mukarere birashobora kugira igiciro gito cya karubone ugereranije nicyakozwe hamwe na 'greener' inzira yisi yose hanyuma igatwarwa mugihe cyo gutanga mugihe gikwiye. Nuburyo bwo gutekereza-sisitemu yo kuramba.

Kurenga Zinc: Umupaka wa Alloying na Nyuma yo Kuvura

Guhanga udushya muri electroplating ntabwo bihagaze. Iragenda yerekeza kumavuta ya zinc. Zinc-nikel, zinc-cobalt, hamwe na zinc-fer bivanze bigenda byiyongera, cyane cyane mubikorwa byimodoka n’inganda zo mu rwego rwo hejuru. Ntabwo aribisekuru bya sogokuru. Urugero, amashanyarazi ya zinc-nikel, arashobora gutanga inshuro 5-10 zo kurwanya ruswa ya zinc yera mubwinshi busa. Nibyo guhindura umukino kugirango urambe.

Kuva kumurongo urambye, ibi birashimishije. Ukoresha misa nkeya kugirango ugere kubuzima bwa serivisi ndende. Inzira ya chimie iraruhije kandi akenshi ni nyirayo, ariko niba bivamo ikintu kimara ubuzima bwinteko itabisimbuye, inyungu yibidukikije ni myinshi. Kugurisha ibicuruzwa ni ikiguzi no kugenzura inzira. Ubu bwogero bwa aliyumu ntibubabarira cyane, busaba kugenzura cyane ubushyuhe, ubwinshi bwubu, na chimie. Nasuye imirongo ikoresha zinc-nikel yogeje ikirere, kandi gukurikirana ntibisiba. Ariko ibisohoka nigice ingaruka zidukikije zahinduwe mumyaka mirongo, ntabwo imyaka.

Noneho hariho umupaka wanyuma: kuvura nyuma yo gufata. Kwimuka kure ya chromium passivates ni intsinzi yibidukikije. Ariko ibisekuru bishya bya silikoni ishingiye kuri titanium, cyangwa se kashe ya polymer ikora ibirenze kwirinda uburozi. Batezimbere cyane imikorere. Bamwe barema hydrophobique hejuru, kumena amazi no kugabanya gutangira kwangirika. Abandi bashiramo amavuta, kugabanya ubushyamirane mugihe cyo kwishyiriraho no kwirinda guhumeka, ibyo bikarinda kwangirika kwimyanda. Aha niho siyanse yubumenyi yongerera imbaraga muburyo burambye - ntabwo ifite umutwe urabagirana, ariko nukwemeza ko igice gishyiraho neza, gikora neza, kandi ntigitererwe mumase kubera ibisate byambukiranya.

None, Nibintu bishya birambye?

Kuzenguruka inyuma kubibazo byumutwe. Icyemezo cyanjye ni: birashoboka, ariko mubisanzwe ntabwo byanze bikunze. Bisanzwe amashanyarazi yamashanyarazi byakozwe kumirongo ishaje, idakora neza hamwe no gucunga nabi imyanda ni net mbi, ibisigisigi. Guhanga udushya-bityo rero kuramba-ntabwo biri mubyiciro byibicuruzwa ubwabyo, ahubwo nukuntu bikozwe kandi bigashyirwa mubikorwa.

Verisiyo irambye isa nkiyi: Yakozwe mubikoresho bigezweho, wenda mumasoko ahuriweho ninganda nkimwe Handan Zitai Yihuta ikora, hamwe nuburyo bukomeye bwo kugenzura kugirango igabanye ubunini butandukanye. Umurongo wa plaque ukoresha sisitemu yo kugarura ibintu bya zinc n'amazi. Ikoresha imikorere-yo hejuru, idafite uburozi passivation layer. Byasobanuwe neza kubisabwa aho uburyo bwo kurinda ibitambo ari byiza, byemeza ubuzima bwa serivisi ntarengwa. Kandi itwarwa binyuze mumurongo utanga isoko neza aho ikoreshwa.

Ibyo ni byinshi 'ifs'. Ukuri nuko, isoko yuzuyemo ubwoko bwombi. Guhanga udushya, ariko biriyongera, birakora, kandi akenshi ntibigaragara kubaguzi ba nyuma. Ikibazo nyacyo ntabwo ari ikoranabuhanga; biri mu guha agaciro no gukorera mu mucyo. Kugeza abaguzi bafite ubushake bwo kwishyura premium-kandi abatanga isoko bafite ubushake bwo kugenzura no kugenzura-inzira irambye rwose inyuma yicisha bugufi gasketi, umutwe wa 'guhanga udushya' bizakomeza kuba ikibazo kuruta amagambo. Kugeza ubu, iracyari umurimo utanga ikizere mu iterambere, hamwe no kwerekana iterambere ryukuri mumaduka meza.
