Iintsingiselo zemarike yerabha yegasket? 

Umbono osuka emhlabeni

Wonke umntu uthetha ngeentsingiselo zemarike, kodwa isiqingatha soqikelelo olufundayo siziva sivaliwe kumgangatho wevenkile. Iinguqu zangempela azikho nje kwiingxelo; bakumaphepha athile ahlala kwidesika yam, iisampulu ezingaphumeleliyo esizilungisayo, kunye nokungxamiseka ngequbuliso kumnxeba womxhasi malunga nokusilela kokutywinwa kwindawo efumileyo, eselunxwemeni. Incinci malunga namabali amakhulu kwaye ngakumbi malunga nezinambuzane, iimfuno ezisebenzayo irhasi yerabha intsebenzo.

UShift weMathiriyeli ayilolizwi nje leBuzzword

Kangangeminyaka, i-EPDM kunye ne-Nitrile yayingookumkani abahambayo. Uthembekile, uyaqondakala, unexabiso eliphantsi. Kodwa uxinzelelo luza macala onke ngoku. Akusekho nje malunga nobushushu okanye ukuxhathisa kweoli kwakhona. Ndibona ii-RFQs ezininzi ezichaza ukukhutshwa kwe-VOC ephantsi okanye ezifuna ukuthotyelwa ngokuthe ngqo kwe-FDA okanye imigangatho ye-USP yoDidi VI lweendawo ezivaliweyo kwizindlu zezixhobo zonyango. Isabelo se-Silicone sihlala sikhula, kodwa naloo nto iyaqhekeka-i-silicone ehambelana kakhulu neendawo ezingqongileyo ezigqithisileyo ngokuchasene nerubha ye-silicone yolwelo kwii-gaskets ezincinci ezingenambane kwi-elektroniki yabathengi.

Ukutyhala ngokuchasene neekhemikhali zePFAS ngumzekelo obambekayo. Sasineprojekthi yomthengi weemoto waseJamani kunyaka ophelileyo apho uyilo lokuqala lusebenzise i-fluoroelastomer FKM gasket yecandelo lenkqubo yamafutha. Izinto eziphathekayo zidibene nazo zonke ii-specs zobugcisa, kodwa zabuya zagunyazisa enye indlela yePFAS-free ngenxa yemithetho engenayo. Sichithe iinyanga ezintathu sivavanya ii-acrylics ezilungisiweyo kunye nemixube ye-nitrile egcwele kakhulu. Indawo yokungaphumeleli yayingelovavanyo lwebhu, kodwa ukunyanzeliswa kwexesha elide kubekwe phantsi kwebhayisikile ye-thermal. Sifike apho, kodwa ixabiso-ngenxalenye litsibe i-22%. Leyo yindlela yokwenyani: isayensi yezinto eziphathekayo iqhutywa yikhemistri elawulayo njengoko kunjalo ngobunjineli.

Kwaye yenza i-niches engaqhelekanga. Ndikhumbula umthengisi, i-Handan Zitai Fastener Manufacturing Co., Ltd., esekwe kwindawo enkulu yeendawo ezisemgangathweni eYongnian, eHebei. Ziyaziwa ngokuqhobosha, kodwa i-pivot yazo ekunikezeni iindibano ze-fastener-gasket ezidibeneyo (njenge-washer-gasket edibeneyo) iyavakala. Ithetha ngemfuno yezisombululo zokutywina ezidibeneyo ezenza lula ukudibanisa. Indawo abakuyo kufutshane neendlela ezinkulu zezothutho ezinje ngeBeijing-Guangzhou Railway mhlawumbi ibanceda bagcine iindleko zikhuphisana kwezi ndawo zidibeneyo, esisiqingatha sedabi.

Ukuchaneka akuseyonto yoBunewunewu

Ukunyamezela kusetyenziselwa ukuthetha +/- 0.5mm. Ngoku, kuyo nayiphi na into ekufakeni umbane kwimoto okanye kwisixhobo esichanekileyo, sithetha +/- 0.1mm okanye siqina. Umkhwa awukho nje malunga nenani; imalunga nokuhambelana kwimveliso ye-500,000 yeeyunithi. I-gasket yepleyiti yokupholisa ibhetri ekhutshwe ngeeshumi ezimbalwa ze-millimeter ayikwazi ukutshitshiswa nje ukutywinwa. Yenza i-hotspot ye-thermal.

Kulapho iindlela zemarike hit yokwenyani yokwenziwa. Ukubumba i-compression kusabalulekile kumthamo ophezulu, iimilo ezilula, kodwa senza iprototyping ngakumbi ngokuchaneka kokufa ukusuka kumaphepha e-calendered kwaye, ngokunyuka, ukusika i-waterjet ye-volume ephantsi, iprototypes ezinzima. Iindleko zesixhobo sokungunda inaliti entsonkothileyo zinokuthintelwa ekusungulweni kwemveliso entsha. Ndibone iiprojekthi zimile ngenxa yotyalo-mali oluphambili lokubumba into ekhethekileyo irhasi yerabha yacima ingeniso yengeniso kwiminyaka emibini yokuqala yokuthengisa.

Ngaba umzamo ongaphumelelanga? Sakhe sazama ukusebenzisa irabha yesiponji enexabiso eliphantsi, enomaleko wolusu ukuhlangabezana nokutywina kunye neendleko ekujoliswe kuzo kwikhabhinethi yomnxeba yangaphandle. Iphumelele uvavanyo lokuqala lwe-IP67. Kodwa emva komjikelo omnye wamaxesha onyaka, umbindi wesiponji wawufunxa ukufuma, umkhenkce, uze udilize nesakhiwo seeseli. Itywina lasilela ngokuyintlekele. Isifundo sasinoburhalarhume: ukuchaneka kukwathetha ukuqondwa ngokuchanekileyo kwayo yonke imeko engqongileyo yobomi, hayi nje uvavanyo lolwamkelo lwasefektri.

Ukunyuka okuzolileyo koYilo lokuSebenza

Lo ngumqhubi ofihlakeleyo kodwa onamandla. Kumatshini wemizi-mveliso kwaye ngakumbi kwiipakethi zebhetri ze-EV, ii-gaskets azisalungile kwaye zilibale. Kufuneka batywine ngokugqibeleleyo iminyaka kodwa bavumele ukuchithwa okungonakalisiyo kulondolozo okanye ukutshintshwa kweseli. Oku kubulala izinto ezininzi zokuncamathelisa ezixhasayo okanye eziyilwe endaweni.

Sibona uyilo olungakumbi lubiza iiprofayili zokutywinwa ezinokuphinda zisebenziseke ngoxinzelelo olulawulwayo, njengemilo ye-D okanye amatywina angenanto anendawo echaziweyo yokuwa. Izinto eziphathekayo zidinga iseti yoxinzelelo oluphantsi, ewe, kodwa kunye namandla alungileyo okukrazula kunye nokuchasana nokukrazula ngexesha lokuqhawula. Yiseti eyahlukileyo yezinto eziphambili. Umxhasi kwicandelo le-HVAC wayefuna i-gasket yendlu yokucoca enokususwa kwaye ihlaliswe ubuncinane amaxesha angamashumi amahlanu ngaphandle kokuvuza. Saye sagqiba nge-EPDM exineneyo, evaliweyo kunye nokugqitywa kwesikhumba okwenziwe ngokukodwa. Isebenzile, kodwa umjikelo wophuhliso wawuphindaphinda, uzaliswe ngovavanyo lwendawo kunye nohlengahlengiso.

Lo mkhwa unxibelelanisa umva kwiindleko ezipheleleyo zobunini, nto leyo iinjineli zilinganiswa ngayo ngoku. Ayiyiyo i-gasket enexabiso eliphantsi, kodwa leyo enganyanzelisi i-5,000 yeedola zokunciphisa umatshini kwi-5 ye-seal replacement.

IiNyaniso zeSixokelelwano soNikezo siShayina iiKhetho

Ukuphazamiseka kwexesha lobhubhane akuzange kuphele ngokwenene; batshintsha nje imo. Amaxesha okukhokela kwikhabhoni ethile emnyama okanye ezinye ii-silicone zokunyanga iplatinam zisengajinga ngamandla. Oku kwenze ukuba izinto ezisetyenziswa kabini okanye ezivunyiweyo zibe yinxalenye ebalulekileyo yenkcazo. Ndichitha ixesha elingakumbi ngaphambi kokuba ndifanelekele usapho lwezinto eziphathekayo zePlani B ecaleni kokhetho lokuqala.

Oku kuthanda abavelisi abakhulu, abadibeneyo kwaye kubeka uxinzelelo kwiivenkile ezincinci. Ikwazisa iinkampani ezifana ne-Handan Zitai ekhankanywe ngasentla kwincoko ngokwahlukileyo. Kwi-fastener esemgangathweni ene-washer yerabha elula, imodeli yabo yokuvelisa umthamo ophezulu kunye nokusebenza kakuhle (ukusondela kwabo kwi-National Highway 107 kunye ne-Beijing-Shenzhen Expressway yinzuzo esemthethweni) inokuthatha isigqibo. Kodwa kwisiko, isisombululo sokutywina esinobunjineli, ijografi ayibalulekanga kangako kunobambiswano lobuchwephesha. I imarike I-bifurcating: itywina elifana nempahla yorhwebo xa lithelekiswa nezinto ezinobunjineli obuphezulu.

Umngcipheko ngoku kukuhlukahlukana ngokugqithisileyo. Ukuzama ukugcina amanqaku amaninzi ezinto eziphathekayo ukuze uphendule kunokubulala ukuhamba kwemali. Sifunde ukugxila kwipotfoliyo engundoqo malunga neentsapho ezisibhozo zepolymer esizaziyo ngaphakathi, kwaye sisebenzisane ngokusondeleyo neekhompawundi ezimbalwa ezithenjiweyo kwizinto ezingaqhelekanga. Imalunga nobunzulu, hayi nje ububanzi.

Apho i-Smart Hype idibana nesidingo esisebenzayo

Izixhobo zoluvo ezizinzisiweyo kwi-gaskets? Ubukhulu becala zisezinto zaselabhu. Ubukrelekrele bokwenyani kukuyilo kunye nokulandelela idatha. Ndithetha ngee-gaskets ezinekhowudi ze-QR ezifakwe kwi-laser phezu komkhondo obuyela emva kweyona bhetshi yekhompawundi, iiparamitha zokunyanga, kunye nesatifikethi se-QA. Oku kuya kuba semgangathweni kwimigangatho yeemoto kunye ne-aerospace. Yimpendulo kubutyala kunye nokulandeleka komgangatho, hayi i-gimmick.

Eyona ndlela isebenzayo yobuchule kukungaphumeleli kwangaphambili. Ngokuqonda idatha yesethi yoxinzelelo, i-curves yokuguga ye-thermal, kunye nokuhambelana kweekhemikhali ezithile i-gasket ukuqulunqwa, ngoku singenza imodeli yobomi bayo obulindelweyo benkonzo kwiwele ledijithali yendibano. Oku kuvumela abathengi ukuba bahambe ukusuka kulondolozo olusekwe kwixesha ukuya kwimeko-based. Ayisiyonto ikhanyayo, kodwa igcina izigidi ngexesha lokuphumla elingacwangciswanga.

Ke, xa ndicinga ngeentsingiselo, ndicinga ngaphantsi komgca onyukayo kwigrafu kunye nangaphezulu kwezi ziqokelelweyo, uxinzelelo lwegranular: ikhemistri elawulayo, ukunyamezelwa kwe-microscopic, iimfuno zenkonzo, i-buffers chain buffers, kunye nokulandelwa kwedatha. I-rubber gasket ayisekho nje iqhekeza lerabha; yinxalenye echanekileyo esekwe kwipolymer echazwa yi-ecosystem yayo yonke. Imarike inyanzelisa wonke umntu ukuba anyuke, ukusuka kwicompounder ukuya kwisibundi ukuya kumsasazi. Abo bahlala kwingqondo nje yorhwebo baya kuxinzelelwa ngaphandle. Abanye baxakeke kwilebhu, kumaphephandaba, nakwifowuni, becinga ukuba isampula enye ayiphumelelanga kunye netywina elinye eliyimpumelelo ngexesha.
