Amathrendi emakethe ye-Rubber gasket? 

Ukubuka Okusuka Phansi

Wonke umuntu ukhuluma ngamathrendi emakethe, kodwa uhhafu wezibikezelo ozifundayo uzizwa unqanyuliwe esitezi sesitolo. Amashifu angempela awekho nje emibikweni; zikumashidi akhethekile ahlala etafuleni lami, amasampula ahlulekile esiwaxazululayo, kanye nokuphuthuma okungazelelwe ocingweni lweklayenti mayelana nokwehluleka kokuvala endaweni enomswakama, esogwini. Kuncane mayelana nezindaba ezinhle futhi okuningi mayelana nezidingo ezinwabuzelayo, ezisebenzayo irasket yerabha ukusebenza.

I-Material Shift Akuyona Nje I-Buzzword

Iminyaka eminingi, i-EPDM kanye ne-Nitrile bekungamakhosi ahamba phambili. Ethembekile, eqondakalayo, eshibhile. Kodwa ingcindezi isiqhamuka nhlangothi zonke manje. Akusekho nje mayelana nezinga lokushisa noma ukumelana nowoyela. Ngibona ama-RFQ engeziwe acacisa ukukhishwa kwe-VOC okuphansi noma adinga ukuthobelana namazinga athile e-FDA noma e-USP Class VI ezivalekile ezindlini zemishini yezokwelapha. Isabelo se-silicone silokhu sikhula, kodwa nalokho kuyahlukana - i-silicone engaguquguquki ephezulu yezindawo ezeqisayo uma iqhathaniswa nerabha ye-silicone ewuketshezi kuma-micro gaskets ayinkimbinkimbi, angenafuleshi kuma-electronics omthengi.

Ukusunduza ngokumelene namakhemikhali e-PFAS kuyisibonelo esiphathekayo. Sibe nephrojekthi yeklayenti lezimoto laseJalimane ngonyaka odlule lapho umklamo wokuqala wasebenzisa i-fluoroelastomer FKM gasket engxenyeni yesistimu kaphethiloli. Izinto ezisetshenziswayo zihlangabezane nazo zonke izici zobuchwepheshe, kodwa zabuya futhi zagunyaza enye indlela yamahhala ye-PFAS ngenxa yemithetho engenayo. Sichithe izinyanga ezintathu sihlola ama-acrylic aguquliwe kanye nemixube ye-nitrile egcwele kakhulu. Iphuzu lokuhluleka bekungelona ukuhlolwa ngelebhu, kodwa ukucindezelwa kwesikhathi eside okusethwe ngaphansi kokuhamba ngebhayisikili okushisayo. Safika lapho, kodwa izindleko-ingxenye ngayinye zeqe ngo-22%. Leyo yinkambiso yangempela: isayensi yezinto ezibonakalayo iqhutshwa amakhemikhali alawulayo kanye nobunjiniyela.

Futhi kudala ama-niches ayinqaba. Ngikhumbula umphakeli, i-Handan Zitai Fastener Manufacturing Co., Ltd., esekelwe kuleyo ndawo enkulukazi yezingxenye ezijwayelekile e-Yongnian, Hebei. Zaziwa ngezixhumi, kodwa i-pivot yazo ekunikeleni ngemihlangano ye-fastener-gasket ehlanganisiwe (njenge-washer-gasket eboshiwe) inengqondo. Ikhuluma ngesidingo sezixazululo ezididiyelwe zokuvala ezenza kube lula ukuhlanganisa. Indawo yabo eduze kwemizila emikhulu yezokuthutha efana ne-Beijing-Guangzhou Railway cishe ibasiza ukuthi bagcine izindleko zincintisana kulezi zingxenye eziyinhlanganisela, okuyingxenye yempi.

Ukunemba akuseyona into ewubukhazikhazi

Ukubekezelela kusetshenziselwa ukusho +/- 0.5mm. Manje, kunoma yini ekufakweni kukagesi ezimotweni noma ekufakweni kahle kwezinto, sikhuluma +/- 0.1mm noma okuqinile. Umkhuba awukona nje ngenombolo; imayelana nokungaguquguquki kuwo wonke ukukhiqizwa kwamayunithi angama-500,000. I-gasket yepuleti lokupholisa ibhethri elicishwe ngezingxenye eziyishumi ezimbalwa zemilimitha ayikwazi ukumane igxishwe ukuze ivalwe. Idala i-hotspot eshisayo.

Lapha kulapho izitayela zemakethe hit yokukhiqiza engokoqobo. Ukubunjwa kokuminyanisa kusabalulekile kumajamo aphezulu, alula, kodwa senza i-prototyping eyengeziwe ngokunemba kokusika kusuka kumashidi anekhalenda futhi, ngokwandayo, ukusikwa kwe-waterjet ngevolumu ephansi, ama-prototypes ayinkimbinkimbi. Izindleko zamathuluzi zokukhunta komjovo oyinkimbinkimbi zingahle zibenqabela ukwethulwa komkhiqizo omusha. Ngibone amaphrojekthi emile ngenxa yokutshalwa kwezimali okuphambili kokukhethekile irasket yerabha wasusa umkhawulo wenzuzo weminyaka emibili yokuqala yokuthengisa.

Umzamo ohlulekile? Sake sazama ukusebenzisa injoloba eshibhile, yesipontshi enongqimba lwesikhumba ukuze sihlangabezane nakho kokubili okuhloswe ukuvala kanye nezindleko zekhabhinethi ye-telecom yangaphandle. Iphumelele ukuhlolwa kokuqala kwe-IP67. Kodwa ngemva komjikelezo owodwa wezinkathi ezithile zonyaka, umgogodla wesiponji wawumunca umswakama, ubanda, futhi ubhidlika ukwakheka kwamangqamuzana. Isigxivizo sehlulekile ngendlela eyinhlekelele. Isifundo besinonya: ukunemba kuphinde kusho ukuqonda okunembayo kwayo yonke imvelo yomjikelezo wokuphila, hhayi nje ukuhlolwa kokwamukelwa kwefekthri.

Ukukhula Okuthulile Kwedizayini Yokusebenza

Lona umshayeli ocashile kodwa onamandla. Emishinini yezimboni futhi ikakhulukazi kumaphakethe ebhethri e-EV, ama-gaskets awasanele nje futhi ayakhohlwa. Zidinga ukuvala kahle iminyaka kodwa futhi zivumele ukuqaqa okungabhubhi ukuze kulungiswe noma kushintshwe iseli. Lokhu kubulala imiklamo eminingi yendabuko enamathelayo esekelwe noma eselashwe endaweni.

Sibona imiklamo eminingi efuna amaphrofayili ophawu angasebenziseka kabusha anokucindezela okulawulwayo, okufana nokuma kwe-D noma ama-seal angenalutho anephoyinti lokugoqa elichaziwe. Izinto ezibonakalayo zidinga isethi yokucindezela ephansi, yebo, kodwa futhi namandla amahle okudabula kanye nokumelana nokusnagging ngesikhathi sokuqaqa. Kuyisethi ehlukile yezinto ezibalulekile. Iklayenti emkhakheni we-HVAC lalifuna i-gasket yesihlungi sezindlu esingasuswa futhi sihlaliswe kabusha okungenani izikhathi ezingamashumi amahlanu ngaphandle kokuvuza. Sagcina sine-EPDM eminyene, yamaseli avaliwe enesikhumba esakhiwe ngokukhethekile. Isebenzile, kodwa umjikelezo wokuthuthukisa ubuphindaphinda, ugcwele ukuhlolwa nokulungiswa kwendawo.

Lo mkhuba uxhuma emuva ezindlekweni eziphelele zobunikazi, okuyilokho onjiniyela abakalwa ngakho manje. Akuyona i-gasket eshibhile, kodwa leyo engaphoqi umshini wokunciphisa u-$5,000 wokushintsha uphawu lwama-$5.

Izinketho Zokubumba Izinto Ezingokoqobo Ze-Supply Chain

Ukuphazamiseka kwenkathi yobhubhane akuzange kuphele ngempela; bavele bashintsha isimo. Izikhathi zokuhola ze-carbon black black noma ama-silicone catalyst athile e-platinum-cure asakwazi ukushwibeka. Lokhu kwenze ukutholakala okumbaxambili noma okugunyaziwe okugunyaziwe kwaba yingxenye ebalulekile yokucaciswa. Ngichitha isikhathi esiningi ngifanelekela umndeni wezinto ezibonakalayo Wohlelo B eduze kwenketho yokuqala.

Lokhu kuthanda abakhiqizi abakhulu, abahlanganisiwe futhi kufaka ingcindezi ezitolo ezincane. Iphinde ilethe izinkampani ezifana no-Handan Zitai oshiwo ngenhla engxoxweni ngendlela ehlukile. Okokubopha okujwayelekile okunomshini wokuwasha werabha olula, imodeli yawo yokukhiqiza ivolumu ephezulu esebenza kahle (ukuba seduze nomgwaqo onguthelawayeka kazwelonke 107 kanye ne-Beijing-Shenzhen Expressway kuyinzuzo esemthethweni) inganquma. Kodwa ngesixazululo esijwayelekile, esinobunjiniyela sokuvala, igeography ibalulekile kunobambiswano lobuchwepheshe. I imakethe i-bifurcating: ama-seal afana nempahla ngokumelene nezingxenye eziklanywe kakhulu.

Ingozi manje ukuhlukahluka kakhulu. Ukuzama ukugcina amamaki ezinto ezibonakalayo amaningi kakhulu ukuze ukwazi ukuphendula kungabulala ukugeleza kwemali. Sifunde ukugxila kuphothifoliyo ewumongo yemindeni eyisishiyagalombili yama-polymer esiyaziyo ngaphandle, futhi sisebenzisane eduze nabahlanganisi abambalwa abathembekile ezintweni ezingavamile. Kumayelana nokujula, hhayi nje ububanzi.

Lapho I-Smart Hype Ihlangabezana Nesidingo Esisebenzayo

Izinzwa ezishumekiwe kuma-gaskets? Ikakhulukazi izinto zisaselebhu. Ubuhlakani bangempela busekuklanyweni nasekulandeleni idatha. Ngikhuluma ngama-gaskets anamakhodi e-QR afakwe nge-laser phezulu alandela emuva eqoqweni eliqondile lenhlanganisela, imingcele yokuphulukisa, nesitifiketi se-QA. Lokhu sekuba yizinga lezigaba zezimoto kanye ne-aerospace. Kuyimpendulo yesibopho sezomthetho kanye nokulandelelwa kwekhwalithi, hhayi i-gimmick.

Umkhuba ohlakaniphile osebenzayo usekuhlulekeni kokubikezela. Ngokuqonda idatha yesethi yokuminyanisa, amajika okuguga ashisayo, nokuhambisana kwamakhemikhali kokuthile gassela ukwakhiwa, manje sesingakwazi ukumodela impilo yayo yesevisi elindelekile kumawele edijithali omhlangano. Lokhu kuvumela amaklayenti ukuthi asuke ekulungiseni okusekelwe esikhathini aye ngokusekelwe esimweni. Ayinabukhazikhazi, kodwa isindisa izigidi ngesikhathi sokuphumula esingahleliwe.

Ngakho-ke, uma ngicabanga ngamathrendi, ngicabanga kancane ngomugqa okhuphukayo kugrafu kanye nokunye kwalokhu okunqwabelene, izingcindezi eziyimbudumbudu: ikhemistri elawulayo, ukubekezelelwa okuncane kakhulu, izimfuno zesevisi, izibhafa ze-supply chain, kanye nokulandeleka kwedatha. I-gasket yenjoloba ayiyona nje ingxenye yerabha; iyingxenye yokunemba esekelwe ku-polymer echazwe yi-ecosystem yayo yonke. Imakethe iphoqa wonke umuntu ukuthi akhuphuke nomfula, kusukela kunhlanganisela kuya kumbumbi kuya kumsabalalisi. Labo abahlala emcabangweni nje wezimpahla bazocindezelwa. Abanye bamatasa elebhu, emaphephandabeni, nasefonini, bethola isampula eyodwa ehlulekile kanye nophawu olulodwa oluphumelelayo ngesikhathi.
