Ukuqina kwe-gasket enezinki ezinombala? 

Ake sinqamule i-marketing fluff. Uma umuntu ebuza ngokuqina kwe-a Umbala we-zinc plated gasket, ngokuvamile bafanekisela lokho kuqedwa okuhle okuluhlaza okwesibhakabhaka, okuphuzi, noma okumnyama kumile phakade. Ukuhlola okungokoqobo: umbala uvame ukuba isixhumanisi esibuthakathaka. Akusona isikhali somlingo; ijazi eliphezulu phezu kwesisekelo se-zinc, futhi izindlela zayo zokuhluleka ziqondile futhi, ngokuhlangenwe nakho kwami, ngokuvamile aziqondwa kahle ekuthengweni kwempahla.

Umbono Oyiphutha Oyinhloko: Umbala Njengokusebenza

Ngibone imidwebo eminingi kakhulu evele ibize i-zinc gasket eluhlaza okwesibhakabhaka, kucatshangwa ukuthi umbala ngokwawo ubonisa izinga eliphezulu lokumelana nokugqwala. Ayikwenzi. Isisekelo sihlala siyi-zinc plating—imvamisa i-blue iridescent conversion coating phezu kwalokho. Umbala uvela kudayi noma ekwelashweni kwesibili okucwiliswe kulolo ungqimba olunezimbotshana zechromate. Ngakho-ke, ukuqina kwehlukana kube izimpi ezimbili: ukuvikelwa kokugqwala komhlatshelo kwe-zinc, nokumelana kongqimba lombala ukuguga, i-UV, nokuchayeka kwamakhemikhali.

Lapho kukhohlisa khona kuhlangana. Isisebenzi esiqinisa ibhawodi, noma i-gasket ehlikihla endlini ngesikhathi sokufakwa, singaklwebha kalula leso singqimba esinombala. Kungazelelwe, unendawo esiliva ecwebezelayo lapho kuvela khona i-zinc eyisisekelo. Akukona ukwehluleka kokuvikela ukugqwala okwamanje, kodwa kubukeka njengokukodwa, futhi ubuhle bubalulekile ezinhlelweni ezibhekene nabathengi. Ngikhumbula inqwaba yama-zinc plated flange gaskets endaweni ebiyelwe kagesi yangaphandle lapho abafaki besebenzisa izishayeli zikagesi. Isokhethi yayifaka izindandatho endaweni emnyama khona kanye ezihlalweni zasekhanda zebhawudi ngaphambi kokuba iyunithi ibone imvula. Iklayenti alizange lijabule ngokubukeka okugqwalile.

Imiphumela yokuhlolwa kwesifutho sikasawoti ixoxa indaba eguquguqukayo. I-chromate eluhlaza okwesibhakabhaka ejwayelekile phezu kwezinc ingase ishaye amahora angu-96 ukugqwala okumhlophe. Izinguqulo ezinemibala, ikakhulukazi ezimnyama ezifana ne-olive drab emnyama noma ye-olive, zingase zibonise ukufiphala kombala noma amabala ngisho nangaphambili, nakuba i-zinc engaphansi isasebenza. Uma i-spec yakho ikhathalela kuphela ukugqwala okubomvu, ulungile isikhashana eside. Kodwa uma ubuqotho bombala buyingxenye yokucaciswa komkhiqizo—ukufaka amakhodi noma ukufaka uphawu—usuvele wehlulekile.

Okungokoqobo Kwezemvelo vs. Izimangalo Zekhathalogi

Khohlwa ilebhu. Ake sikhulume ngendawo yenjini eshisayo, enomswakama, noma isakhiwo esingaphandle eduze nogu. Ukuchayeka kwe-UV kuwukubulala odayi bemvelo. Lobo luhlaza okwesibhakabhaka obukhazimulayo ku-washer enepuleti kubakaki belanga lungashintsha ubisi, luhlaza okwesibhakabhaka ngokuphaphathekile ngesizini eyodwa. I-chromate ngaphansi yenza umsebenzi wayo, kodwa inkomba yokubuka ayisekho. Ukuchayeka kwamakhemikhali ngesinye isilo. Ngike ngabona ama-gaskets anombala obomvu we-zinc esetshenziswa emishinini lapho ngezikhathi ezithile isifutho se-hydraulic fluid siphendule umbala ube yimfucumfucu ephinki. Uketshezi aluzange luhlasele i-zinc, kodwa lwancibilikisa udayi.

Yilapho ukukhetha kwezinto ezibonakalayo kukuluma khona. A Umbala we-zinc plated gasket kuvame ukukhethwa njengenye indlela engabizi kunensimbi engagqwali noma i-hot-dip galvanizing yezindawo ezimaphakathi. Kodwa ukulinganisela kuyisihluthulelo. Kuphaneli eyomile, yasendlini lapho ngokuvamile ihlonzwa khona? Ukukhetha okuhle kakhulu. Kunoma yini ene-condensation, ukuhamba ngebhayisikili okushisayo njalo, noma ukuhuzuka, usesikhathini sokubolekwa. Isihlahla sesinqumo akufanele siqale ngokuthi sifuna okuluhlaza okwesibhakabhaka, kodwa sizothinta ngani ngempela?

Senze isivivinyo sokuqhathanisa eminyakeni embalwa edlule ngezingxenye ezisuka kusizinda sokukhiqiza esikhulu njenge-Yongnian e-Hebei. Sibe ne-zinc ejwayelekile, i-chromate eluhlaza okwesibhakabhaka, nama-gaskets ane-oxidized emnyama endaweni yokuhlola endaweni engaphandle evikelekile kancane. Ingubo emnyama ibonise ukufiphala okugqamile phakathi nezinyanga ezi-4. Umbala oluhlaza okwesibhakabhaka ubambe kangcono umbala kodwa uthuthukise imikhiqizo emhlophe egqwalile emaphethelweni ngokushesha. I-zinc engenalutho yayibukeka ibuthuntu ngendlela efanayo kodwa ayizange iqhubekele ekugqwaleni okubomvu ngokushesha okukhulu. Kwakuyisifundo esicacile: isendlalelo esingeziwe sombala kwesinye isikhathi singadala imifantu emincane ngokungaqondile noma ukuhluka kwesendlalelo sechromate okuba amaphuzu okuqalisa ukugqwala.

Ukuguquguquka Kokukhiqiza: Konke Kusenqubweni

Ukuqina akukhona nje mayelana nokucaciswa kwezinto; iboshelwe ngokujulile ekulawuleni inqubo. Umphakeli owaziwayo njengo I-Handan Zitai Fetesser Comment Co, Ltd., isebenzisa indawo yayo kusisekelo sengxenye enkulu kunazo zonke yaseShayina, ngokuvamile inesilinganiso nenqubo eyehlayo. Kodwa nalapho, udeveli usemininingwaneni. Izinyathelo ezibalulekile ukulungiswa kwendawo ngaphambi kokucwecwa, ukujiya nokulingana kwediphozi ye-zinc, isikhathi nokugxilisa ingqondo kubhavu we-chromate, kanye nezinga lokushisa nokuvalwa kokugeza okudayi.

Isinyathelo se-chromate esheshayo noma udayi ovalwe ngokungafanele kuzoholela ekwehlulekeni ngaphambi kwesikhathi. Ngithole amaqoqo lapho umbala ukhuhla khona ngokucindezela komunwe. Leyo yinkinga yokuvalwa kwe-post-plating. I-substrate nayo ibalulekile. I-gasket egxivizwe ngensimbi enekhabhoni ephansi iqhathaniswa neyodwa evela ku-alloy yezinga eliphezulu izoba nokuthungwa okuhlukile kwendawo ngemva kokuhlanza, okuthinta ukunamathela kwamapulangwe. I-Handan Zitai Fetesser Comment Co, Ltd. futhi abakhiqizi abakhulu abafanayo banenzuzo yokungaguquguquki kwezinto ezingavuthiwe kanye nemigqa ezenzakalelayo, okunciphisa lokhu kuhlukahluka uma kuqhathaniswa nezitolo ezincane zemisebenzi.

Ithiphu elilodwa elisebenzayo engihlala ngilinikeza: cela ukuhlolwa kwetheyiphu elula (nge-ASTM D3359) kumasampuli. Akuyona indinganiso ye-fasteners, kodwa ikutshela mayelana nokunamathela. Cindezela ucezu lwetheyiphu enamathelayo eqinile endaweni enombala, uyiklebhule. Uma umbala ufika nawo, unenkinga yokubopha ezovela endleleni yokuhamba noma yokuhlanganisa.

Isetshenziswa Nini, Futhi Nini Ukuhamba

Ngakho, ingabe konke kubi? Cha. Imayelana nokulindelwe okuphethwe. Ezingxenyeni zangaphakathi ezisendaweni eyomile, elawulwayo—cabanga ngamaracks eseva, ama-server ahlanganisayo, noma amaphaneli emishini yangaphakathi—ukufakwa kwe-zinc okunemibala kuhle kakhulu ekuhlonzweni kwengxenye futhi kubukeka kuchwepheshe. Ukuqina kwayo kwanele ngokuphelele. Futhi, ezinsizeni ezidinga ukuvikela okuthile kwe-EMI/RFI, isisekelo se-zinc sihlinzeka ngokusebenza, futhi umbala ungasetshenziswa ukukhombisa indlela ethile yokubeka phansi noma yesignali.

Ukwehluleka kuvela ekusebenziseni kabi. Ngiye ngeluleka ngokumelene nokuwasebenzisela ingxenye yemoto eyisikwe phansi kanye, kodwa ithimba ledizayini lamiswa endaweni emnyama ukuze kulungiswe ubuhle. Bayihlola ekamelweni futhi yaphumelela ukuhlolwa kokugqwala komjikelezo omfushane. Umhlaba wangempela? Usawoti wasemgwaqweni, ukuqhekeka kwetshe, kanye nomswakama ongapheli kuholele ekuhlulekeni kwezimonyo esikhathini esingaphansi konyaka. Sashintshela emshinini wokuphehla ugesi onejazi elimnyama, elalimba eqolo kodwa elihlala njalo. Isifundo: fanisa ukucaciswa kwendawo yangempela, eqinile, hhayi efanelekile.

Enye i-niche kodwa iphuzu elibalulekile: ukuhambisana kwe-galvanic. I-zinc-plated steel gasket ngokumelene nendlu ye-aluminium idala umbhangqwana we-galvanic, kodwa i-zinc iseduze ne-aluminium esikalini sobuhle, ngakho-ke ayinalo ulaka kunokuba, ake sithi, i-gasket yensimbi engenalutho. Umbala wombala wengeza umgoqo omncane, ongaqhubeki, onganciphisa kancane umthamo we-galvanic uma uphelele. Kodwa uma usuphelile, ubuyela ku-zinc-aluminium contact. Kuyinto encane, kodwa ezindaweni ezibucayi zikagesi, isohlwini lokuhlola.

Ngale Kweplate: Ezinye Izindlela

Lapho imvelo idinga umbala kodwa futhi ukuqina okukhulu, kufanele ubheke ngalé kombala ojwayelekile we-electroplated zinc. Amajiyometri afana nama-gaskets, anemiphetho yawo kanye nezimo eziyinkimbinkimbi ezinesitembu, kuyinselele ukujamba ngokulinganayo. Enye indlela ukucwenga ngomshini ngombala, okunganikeza ukujiya okungcono emaphethelweni. Enye i-powder coating, kodwa lokho kwengeza ukujiya okuphawulekayo futhi kungathinta ukucindezelwa kuhlelo lokusebenza lwe-gasket-kungaphezu kwesembozo noma amabakaki.

Ukuze uthole ukuqina okuphezulu, impendulo ngokuvamile iwukuba uhlukanise umsebenzi embala. Sebenzisa isiphetho esiqinile njengeGeomet? noma i-Dacromet? ukuze kuvikeleke ukugqwala, bese wengeza ipheshi elinemibala, iwasha ye-aluminium anodized, noma uphawu olupendiwe lokuhlonza. Kubiza kakhulu, kodwa ubunjiniyela obuthembekile. Ngezinye izikhathi, isixazululo esingcono kakhulu ukusebenzisa i-gasket egcwele i-zinc-nickel engenalutho, yekhwalithi ephezulu futhi wamukele umbala ongathathi hlangothi wesiliva-grey. Ukumelana kwayo nesifutho sikasawoti kungaba amahora angama-500+, kufiphaze noma iyiphi i-chromate enemibala.

Ekugcineni, ukucacisa a Umbala we-zinc plated gasket ibhalansi yezindleko, ubuhle, kanye nokuchayeka emhlabeni wangempela. Iphelele ngokuphelele uma isetshenziswa ngamehlo acacile. Ungasithembi isimangalo sokumelana nokugqwala okuphezulu kwekhathalogi ngenani lobuso. Thola amasampula, uwabeke ngaphansi kwesimo sakho esingokoqobo—igumbi lomswakamo, ibhokisi le-UV, okokusula kancane—futhi ubone ukuthi yini ehlulekayo kuqala. Amehlo akho nengilazi yokukhulisa kalula izokutshela ngaphezu kwanoma yiliphi ishidi ledatha elijwayelekile elivela kumnikezeli, ngisho neliqinile elisekelwe kuhabhu enkulu efana UHanan Zitai. Ukungaguquguquki kwabo kukuthola isiqalo esihle, kodwa isicelo sakho sichaza umugqa wokugcina.
