Indima ye-foam gasket kwitekhnoloji eluhlaza? 

Uyazi, xa abantu bethetha ngetekhnoloji eluhlaza, batsibela kwangoko kwiipaneli zelanga, iiinjini zomoya, okanye iiseli zehydrogen. Kunqabile ukuba nabani na azise iigaskets zogwebu. Leyo yimpazamo yokuqala. Ngokwenyani, ukuba ukhe waba kumgangatho wefektri uhlanganisa indawo ebiyelweyo yebhetri okanye utywine umtshintshi wobushushu, uyazi ukuba i-gasket ekhethwe kakubi inokujongela phantsi ukusebenza kakuhle kwenkqubo yonke. Akunjalo nje ngokutywinwa; imalunga nolawulo lwe-thermal, i-vibration damping, kunye nokuphila ixesha elide. Ndizibonile iiprojekthi apho ugxininiso lobunjineli lwaluphelele ngokupheleleyo kumacandelo aphambili, kuphela ukuba nokusilela kwebala kulandelelwe ukuthotywa kwe-gasket okanye ukuphuma kwegesi okungcolise iindawo ezibuthathaka. Kulapho incoko yokwenyani kufuneka iqale khona.

IsiNxulumanisi esiNgahoywanga

Kwiinkqubo zeteknoloji eluhlaza-cinga iinkqubo zokugcina amandla ebhetri ye-industrial-scale (BESS) okanye iikhabhinethi ze-photovoltaic inverter zangaphandle-ukutywinwa kwendalo kubalulekile. Kodwa ayikokugcina amanzi ngaphandle nje. Imalunga nokulawula i-micro-esingqongileyo ngaphakathi. Isixokelelwano esivaliweyo sokupholisa ulwelo kwipakethi yebhetri, umzekelo, ixhomekeke kwigaskets ukugcina uxinzelelo kunye nokuthintela ukuvuza kwesipholisi. Ukuba i-foam compresses isethi ayilungile, okanye izinto eziphathekayo azihambelani ne-coolant, ufumana i-seepage. Eso sisipholisi, esihlala silulwelo olukhethekileyo lwe-dielectric, siyabiza kwaye ilahleko yaso ibetha ngokuthe ngqo iimethrikhi ezisebenzayo. Ndikhumbula uvavanyo apho iyunithi yomntu okhuphisana nayo yasilelayo ukufumana isatifikethi se-IP67 hayi ngenxa yoyilo, kodwa ngenxa yokuba i-gasket yogwebu ebonelelweyo yayinolwakhiwo lweeseli olungangqinelaniyo, olukhokelela kukusilela koxinzelelo lwasekhaya. Ukulungiswa kwakungekho ngokutsha, kodwa ukutshintshwa kwezinto ezibonakalayo kwiyunifomu engaphezulu, i-foam ye-polyethylene edibeneyo.

Emva koko kukho inkalo ye-thermal. Abaninzi bacinga ukuba isinyithi okanye irabha yeyona ndlela yokuya kwiipads ezishushu. Kodwa kwizicelo ezifuna ukugqunywa kunye nokutywinwa, njengendlu yeyunithi yokulawula impompo yobushushu bomthombo womoya, igasket egqunywe ngesilicone ye-urethane yegwebu yenza imisebenzi emibini. Itywina ikhabhinethi ngokuchasene nothuli kunye nokufuma ngelixa ibonelela ngekhefu le-thermal ukuthintela ukuxinana kwi-elektroniki yangaphakathi. Into ephambili kukugqithiswa kwengubo kunye nesantya sokubuyisela i-foam. Ukuba ukubuyiswa kucotha kakhulu emva koxinzelelo ngexesha lokudibanisa, isitywina siphumla phezu kwemijikelo ye-thermal. Sifunde oku ngendlela enzima kwiprojekthi yokuqala, sisebenzisa ugwebu oluqhelekileyo lwe-rebond oluqhube kakuhle kuvavanyo olungatshintshiyo kodwa lwasilela emva kweenyanga ezintandathu zokukhwela ibhayisekile yemihla ngemihla. Umsantsa owenziwe wavumela ukungena komoya ofumileyo, okukhokelela kumhlwa kwiibhloko zetheminali.

Ukukhetha izinto eziphathekayo ngomnye umgibe. "Okuhlaza" akufuneki kubhekisele kwisicelo kuphela kodwa i-gasket ngokwayo. I-chlorinated okanye i-brominated flame retardants kwi-foam, eqhelekileyo ukuhlangabezana ne-UL 94 V-0 kwizinto zombane, inokungavisisani ne-ethos ye-full-lifecycle ye-green tech ukuba zenza nzima ukurisayikilishwa. Kukho ukutyhala ukuya kwi-halogen-free, i-silicone-based intumescent foams. Ziyanda phantsi kobushushu ukuze zivale izikhewu nangcono, ipropathi ebaluleke kakhulu kwizicwangciso zokulawula umlilo webhetri ipakethe. Ukucacisa ezi akusoloko kuthe ngqo; iindleko zabo ziphezulu kwaye iiparamitha zokucubungula ngexesha lokufa ziqina. Amandla omthengisi apha kukwenza okanye ukuqhawula.

Emhlabeni: IiNyaniso zezoThutho kunye noBonelelo

Oku kundizisa kwinto ephathekayo: ijografi kunye nolungiselelo. Imveliso yala macandelo akhethekileyo ayisasazwanga ngokulinganayo. Kwivolumu ephezulu, iinxalenye zegwebu ezichanekileyo, udinga umthengisi onenkxaso eyomeleleyo yesayensi kunye nokuveliswa okufanayo. Ndisebenze kunye namaqabane kwiziseko eziphambili zemizi-mveliso apho inkqubo yendalo ixhasa oku. Umzekelo, I-Sunnian Zitai Festener Fishaner Comment Com., esebenza ukusuka kweyona nxalenye inkulu yomgangatho wemveliso eChina eYongnian, eHandan, izisa imbono efanelekileyo. Ngelixa zaziwa ngokuba zii-fasteners, ii-hubs ezinjalo zihlala zinobuchule obusondeleyo kwizisombululo zokutywinwa ngenxa yendalo edibeneyo yokuhlanganisa. Indawo yabo kufuphi nemithambo ephambili yothutho efana neBeijing-Guangzhou Railway kunye neNational Highway 107 ayingomgca nje kwiwebhusayithi (https //wwww.ziitasteners.com); iguqulela kulungiselelo olubambekayo. Xa ulawula nje-ngexesha lokudityaniswa kweendibano ze-nacelle zeinjini yomoya kwizibuko laseTianjin, ukuba nomboneleli wegasket onokuthembakalisa ukuhambisa imveliso ngendlela kunye nomzila kaloliwe ngaphandle kokulibaziseka yinxalenye engaxoxiswanayo yenxaki ethembekileyo. I-gasket ehleli kwindawo yokugcina izibuko ayitywini nantoni na.

Kodwa ukusondela akuyona yonke into. Ndibone ababoneleli kwiindawo ezidityaniswe kakuhle abasatyhafayo ekulandeleni izinto eziphathekayo. Kubuchwephesha obuluhlaza, ngakumbi kumacandelo adityaniswe nezinto ezipholisayo okanye kwiindlela zomoya (njengakwizixa ze-electrolyzer), udinga amaxwebhu apheleleyo malunga nokwakheka kwepolymer kunye nezinto ezinokuvuzeka. Umthengisi ufuna uqeqesho ukuze abonelele ngezatifikethi ezingqamene nebhetshi. Kulapho inkcubeko yokusebenza yeqela lemveliso ibalulekile. Ukuxinana kwabavelisi bamacandelo kwindawo efana neYongnian kunokukhuthaza ukhuphiswano kumgangatho, hayi nje ixabiso. Kwiprojekthi ebandakanya iiseli zamafutha e-PEM, safumana iigaskiti ze-foam ezifakwe kwikhabhoni eziqhutywayo ukuze kutywinwe ipleyiti ye-bipolar. Iisampulu zokuqala ezivela kwiworkshop yasekhaya aziphumelelanga iimvavanyo ze-conductivity emva kokuguga kwigesi ehlaziyiweyo. Umba yayikukufuduka okubophelelayo. Sitshintshele kwiprosesa esekwe ngakumbi enokulawula inkqubo yekhalenda ngcono, kwaye yenzeka ukuba ibekwe kulo mmandla ubanzi wemizi-mveliso, ixhasa amakhonkco okubonelela ngezinto apho.

Iintsilelo zihlala zivela kwi-interface phakathi kwe-gasket kunye ne-fastener, ngokoqobo. Igaskithi yogwebu ecinezelwe ngebholithi ejikeleze ihatch yenkonzo kwi-solar tracker drive. Ukuba i-torque ye-fastener ayicaciswanga ngokubambisana ne-gasket's compression stress-strain curve, mhlawumbi ungaphantsi kwe-compress (ukuvuza) okanye ucinezele (utyumle ngokusisigxina i-foam, ukulahlekelwa ukubuyiswa kunye nokutywinwa). Yiyo loo nto iinkampani eziqondayo zombini ukuqinisa kunye nokutywinwa, njenge umenzi we-fastener ukwahlukahlukana kwiimveliso zokutywina, kunokuba nendlela enengqondo. Bafumana inkqubo yoomatshini. Iwebhusayithi yeZitai Fasteners ikhankanya ukugxila kwabo kwimveliso yamalungu asemgangathweni; olu lwazi lusisiseko lubalulekile. I-gasket ayifane ibe sisiqithi; yinxalenye yendibano edibeneyo edibeneyo.

Imeko kwindawo: Ukuvuza kweModyuli yebhetri

Makhe ndichaze uphando oluthile. Umxhasi uxele ukuhla kancinci ekusebenzeni kokupholisa kwiimodyuli zebhetri ye-lithium-ion kwiibhasi zombane. Iimodyuli zapholiswa ngamanzi ngepleyiti ebandayo. Umfanekiso we-Thermal ubonise ukuhanjiswa kobushushu obungalinganiyo. Saqhawula iyunithi kwaye safumana i-gasket yesitishi esipholileyo-i-EPDM encinci, i-foam eshinyeneyo kunye ne-adhesive layer-yayincitshiswe ngokuyinxenye kwaye yavumela indlela yokuvuza yomzuzu. Isipholisa sasinobubi obucothayo kugwebu olumeleneyo olukhuselayo, luthoba umgangatho waso wobushushu. Unobangela wengcambu wawungeyena i-adhesive ekuqaleni, kodwa ukulungiswa komphezulu wepleyiti ebandayo ye-aluminium. Yayinendawo yokusila eyayigudileyo kakhulu ukuba isincamathelisi senze iqhina elihlala lihleli, elidityaniswe nokungahambelani kokwandiswa kobushushu. "Ukulungiswa" kwintsimi kwakukusebenzisa i-silicone bead, engcolileyo kwaye ingathembeki. Isisombululo esifanelekileyo sasikutshintshela kwi-gasket kunye nenkqubo yokuncamathela eyahlukileyo kwaye uchaze ukunyanzeliswa kwe-abrasive pretreatment ye-aluminium. I-gasket material ngokwayo yayilungile; ukusilela ibingumba wodibaniso lwenkqubo. Oku kuqhelekileyo-i I-foam gamket ithatha ityala, kodwa ingxaki ihlala ikuyilo lokudityaniswa okanye ubume bomgangatho.

La mava asityhalele ukuba sijonge ngokusondeleyo kumagwebu eeseli ezivaliweyo ngokuchasene neseli evulekileyo yojongano lolwelo. Iseli evaliweyo inomdla wokutywinwa kolwelo, kodwa ukuba yirhasi (njengakwinqanawa yokugcina amandla omoya ecinezelekileyo), izinga lokusasazwa kwimatrix yogwebu libaluleke ngakumbi. Kwicompressor yehydrogen, siye savavanya amagwebu amaninzi e-fluorosilicone. Imowudi yokungaphumeleli yayingavuzi ngokwe-se nganye, kodwa i-hydrogen embrittlement yesibophelelo sogwebu ngokuhamba kwexesha, isenza ukuba i-gasket ibe brittle kwaye ithande ukuba nothuli ngexesha lokuqhaqha ukuze kugcinwe. Olo ngcoliso luyingxaki enkulu. Saye sagqiba ukufudukela kwi-PTFE-based foam eyandisiweyo, eyayinokumelana neekhemikhali ezingcono kodwa yayiyinkathazo yokufa-ukusika ngokucocekileyo ngaphandle kokukrazula. Umthengisi kwafuneka atyale imali kwisixhobo esitsha. Lonke ukhetho lunesiphumo esiqhekezayo.

Ngaphaya kokutywinwa: I-Acoustic kunye neVibration Damping

Indima ekuxoxwa ngayo kancinci yingxolo kunye nokungcangcazela. Ufakelo olukhulu lwetekhnoloji eluhlaza-iibhokisi zegiya zomoya, iiholo ze-hydroelectric turbine, iicompressor zamashishini zokubanjwa kwekhabhoni-ziyangxola. Iigasthi zogwebu kwiiphaneli zokufikelela naphakathi kwamacandelo olwakhiwo negalelo ekudakaleni kwe-acoustic. Kodwa ayisiyonto nje yokuqhwaba elona gwebu lingqindilili. I-vinyl elayishwe ngobuninzi kunye ne-foam backing ixhaphakile, kodwa ubuninzi be-foam kunye nobukhulu kufuneka bulungelelaniswe kwi-frequency target. Kwiprojekthi yekhabhinethi yokulawula umbane wejenereyitha, uyilo lokuqala lusebenzise igwebu elivakalayo eliqhelekileyo. Yathomalalisa ingxolo ephezulu-frequency kakuhle kodwa akenzanga nto kwi-low-frequency hum evela kwii-transformers, esona sikhalazo siphambili. Kwafuneka senze imodeli yenkqubo kwaye sicacise i-foam eninzi ene-barrier septum. Iindleko zonyukile, kodwa inkcazo yokusebenza yahlangatyezwa. Nabu bubuchwephesha obuluhlaza: ukuphucula indawo yokusebenza kunye nokunciphisa ungcoliseko lwengxolo.

Ukunyibilika kweVibration kubalulekile kubomi obude. Kwiinkqubo zokulandela umkhondo welanga, iidrives kunye ne-actuator zixhomekeke rhoqo, ukunyakaza okuncinci kunye nokungcangcazela okubangelwa ngumoya. I-gasket yogwebu kwiindawo zokukhwela inokuthintela ukubola kunye nokukhululeka. Ndikhumbula ndihlola ifama yelanga apho uqhagamshelo lwebholithi kwimiqolo yeetrakhi ziye zakhululwa. Uyilo lwantlandlolo lwalunewasha esicaba engenanto. Ukubuyisela kwakhona nge-washer eyayinoluhlu oludibeneyo lwe-EPDM lwe-foam kwelinye icala yasombulula umba. I-foam yayisebenza njenge washer yokutshixa isitshixo sohlobo, igcina umthwalo obambeleyo. Licandelo elincinci, kodwa kumawakawaka abalandeli, ithintela iintloko ezinkulu ze-O&M. Olu luhlobo lwesicelo esisebenzayo, esingathandekiyo apho iigaskets zogwebu zifumana ukugcinwa kwazo.

UZinzo Loop

Ekugqibeleni, makhe sithethe ngesiphelo sobomi. Imveliso yeteknoloji eluhlaza ngokwenene iqwalasela ukuchithwa kunye nokubuyisela izinto eziphathekayo. Iigasthi ezinogwebu ezincamathela ngoxinzelelo (i-PSA) ziyingozi kakhulu kubashicileli. Zingcolisa imijelo ye-aluminiyam okanye yeplastiki. Kukho umdla okhulayo kwi-gaskets ye-thermoplastic foam enokuthi ihlulwe ubushushu okanye ihambelane nomjelo wokuphinda usetyenziswe kwizinto ezisisiseko. Umzekelo, i-polyolefin foam gasket ekwindlu yebhetri ye-polypropylene inokuyilwa ukuba inyibilike kwaye ixutywe ngexesha lenkqubo yokurisayikilisha yePP ngaphandle kokuthotywa komgangatho. Oku kuphambili kwaye akukabikho semgangathweni. Sithathe inxaxheba kumqhubi we-EV ojonge oku. Umceli mngeni yayikukufumana ugwebu oludibana nokungakhathali kwedangatye, ukusebenza kokutywinwa, kunye ne-trifecta yokuphinda isetyenziswe. I-compromise yangoku isebenzisa idizayini eyahlulahlulayo: i-clip-in foam strip ngaphandle kokunamathela. Isebenza ukuba uyilo lwezindlu lune-groove efanelekileyo, kodwa yongeza amanyathelo endibano. Lurhwebo-off.

Ke, sithini isigqibo? Indima ye i-foam gasket kwitekhnoloji eluhlaza ngokusisiseko imalunga nemfezeko yenkqubo kunye nokusebenza kakuhle kujongano. Yinkcukacha yentsimi ekala. Ukukhetha kakubi i-gasket kunokukhokelela ekulahlekeni kwamandla (i-thermal, fluid), ukusilela kwangaphambi kwexesha, ukugcinwa okwandisiweyo, kunye neengxaki zokuphinda zisetyenziswe. Olona qheliselo lungcono lubandakanya ukucinga ngayo njengecandelo lenkqubo kwasekuqaleni, ukuqonda ukusebenzisana kwayo kwezinto eziphathekayo, kunye nokukhangela kubathengisi ababamba imeko yomatshini kunye nokusingqongileyo. Ayisiyonto yorhwebo. Ekutyhaleni itekhnoloji eluhlaza, ngamanye amaxesha elona tywina lincinci lelona libambe ukuvuza okukhulu-kwintsebenzo, ukuthembeka, kwaye ekugqibeleni, isithembiso sendalo ngokwayo.
