RTV vs Viton gasket: ukhetho olungcono? 

Uyabona le ngxoxo-mpikiswano iphuma ngalo lonke ixesha kwiiforamu kunye nakwivenkile ephantsi: usebenzisa nini i-RTV sealant xa ithelekiswa ne-Gasket ye-Viton eyenziwe ngoomatshini okanye ebunjiweyo? Impendulo emfutshane kukuba, akukho namnye. Impendulo ende kulapho izinto ziba bubugxwayiba, zibiza kakhulu, kwaye ngokungafihlisiyo, apho uninzi lwabantu zifumana impazamo ngokuzithatha njengezibambela ngqo. Zizizisombululo ezahlukeneyo ngokusisiseko kwiingxaki ezahlukeneyo.

Ukungaqondi kakuhle: I-Sealant vs. Gasket

Masiyicacise le nto kuqala. RTV (Igumbi lobushushu Vulcanizing) silicone a ifomu-kwindawo gasket. Uyikhama ngaphandle kwetyhubhu, iphilisa emoyeni, kwaye izalise isithuba. A I-viton gasket (i-FKM i-fluoroelastomer) i-pre-formed, icandelo eliqinileyo owela kulo. Impazamo enkulu endiyibonayo ngumntu obamba i-RTV kuba ikhawuleza kwi-flange efuna ngokwenene ukutyumza okuchanekileyo kunye nokuchasana kweekhemikhali zesiqwenga esifanelekileyo seViton. Ndibe netyala ngale nto kwangethuba, ndicinga ukuba i-bead ye-RTV ephezulu inokusingatha umgca weoli eshushu. Ayizange isilele kwangoko, kodwa yalila emva kwemijikelo embalwa yobushushu. Ubuso be-flange babungekho tyaba ngokugqibeleleyo-into i-gasket ebunjiweyo ihlawulela, kodwa i-bead encinci ye-RTV ayikwazi ukubhula.

Amandla e-RTV akwindawo engaqhelekanga, izicelo ezinoxinzelelo oluphantsi, okanye apho kufuneka utywine iindawo ezintathu okanye ngaphezulu zokukhwelana kwindawo edibeneyo. Cinga izigqubuthelo zevalvu, iimeko zekhonkco lexesha. Iyakuxolela. Amandla kaViton achazwe, uxinzelelo oluphezulu, ubushushu obuphezulu, okanye kwindawo yeekhemikhali ezinobundlobongela. Cinga iinkqubo zamafutha, imigca yeoli ye-turbocharger, iimpompo ze-solvent ezinobundlobongela. Ichanekile.

Ukhetho luhlala luhla kwimeko yobuso be-flange. Ukuba zifakwe, zigxothiwe, okanye zijijelwe ngaphaya kwamawaka ambalwa e-intshi, i-RTV inokuba lolona khetho lufanelekileyo ngaphandle komatshini. Kodwa ukuba unobuso obucocekileyo, obusicaba, obuhambelanayo, i-gasket eqinile iphantse ihlale iphezulu ukuthembeka kwexesha elide kunye noxinzelelo lokutywinwa olungaguqukiyo.

Ukunyangwa kweMichiza: Apho iViton ifumana ukugcinwa kwayo

Le app umbulali for Viton. I-silicones ye-RTV ilungile ngokuchasene namanzi, izinto zokupholisa, kunye neeoli ezithile. Kodwa yazisa amafutha (ingakumbi imixube yanamhlanje kunye ne-ethanol), i-transmission fluid, i-brake fluid, okanye izinyibilikisi ezinamandla, kunye ne-RTV eqhelekileyo ijika ibe yi-mush. Kukho ii-RTV ezikhethekileyo ze-fluorosilicone, kodwa zinexabiso kwaye azikaqini njengeViton eyomeleleyo.

Ndikhumbula iprojekthi ebandakanya i-rig encinci yovavanyo lwe-biodiesel. Sasebenzisa iRTV ebomvu yegeneric kwisihluzo sezindlu. Kwisithuba esingangeveki, itywina lalidumbile lathamba, nto leyo eyayibangela ukuvuza okukhulu. Ukutshintshela kwi-75-durometer efanelekileyo iViton O-ring (yayingeyonto i-gasket flat) kwaye ingxaki yaphela iminyaka. Iindleko zeViton inxalenye yayiphezulu, kodwa ixesha lokuphumla kunye nokucoca kwi-RTV engaphumelelanga yayiphindwe kalishumi. Luqoqosho lobuxoki lwakudala.

Ngalo lonke ixesha khangela iitshathi zokuhambelana kweekhemikhali. Kwiihydrocarbons, aromatics, kunye neeasidi, iViton (FKM) iqhelekile. Kwinkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esebenza kwisiseko esikhulu somgangatho wemveliso yeYongnian, ukhetho lwendlela yokutywina aluchaphazeli nje umsebenzi we-fastener kodwa ingqibelelo yendibano iphela. Baza kuqonda ukuba ukucacisa itywina elichanekileyo kubaluleke kakhulu njengokuchaza ibakala elifanelekileyo le-12.9 bolt.

Iqondo lobushushu kunye noxinzelelo lwenyani

Ii-silicones ze-RTV zihlala zithengiswa njengobushushu obuphezulu, okuyinyani-ezinye ziyakwazi ukusingatha i-spikes ephakathi ukuya kwi-500 ° F / 260 ° C. Kodwa le yimpahla ephilisiwe. Into ephambili kukushisa okusebenzayo okuqhubekayo kunye noxinzelelo. I-Viton gasket inokuphatha i-400 ° F / 204 ° C ngokuqhubekayo kunye noxinzelelo oluphezulu kakhulu ngenxa yokuba i-elastomer edibeneyo, edibeneyo. I-RTV yenza ulusu kwaye iphilisa ngaphakathi, ngoko ke iipropathi zayo ezininzi azifani.

Kwi-exhaust yokulungisa ijenereyitha, sizame i-RTV yobushushu obuphezulu be-copper kwi-flange ejijekileyo njengento yokulungisa ngokukhawuleza. Yatsha yaza yajika yangumgubo malunga neeyure ezingama-48 zokusebenza ngokuqhubekayo. Ubushushu bebungatshintshi kwaye buphezulu kakhulu, kunye nokukhwela ibhayisekile. Siye salungisa i-flange flat kwaye sasebenzisa i-gasket yentsimbi elalayo-irhamncwa elahlukileyo lilonke-kodwa inqaku lelokuba, ne-RTV yobushushu obuphezulu inefestile ecacileyo, ehlala iqikelelwa kakhulu.

Ukutywinwa kwe-static kwiinkqubo ze-oyile eshushu (zithi, i-250 ° F / 121 ° C ngokuqhubekayo), i-gasket ye-Viton ikwindawo yayo yokuthuthuzela. I-RTV apho inokusinda, kodwa ngokuhamba kwexesha, inokuqina kwaye ibe brittle, iphulukane namandla ayo okutywina.

Isicelo esiSebenzayo kunye neFactor Feel

Le zizinto abangazifaki kumaphepha edatha. Ukusebenzisa i-RTV ngokuchanekileyo bubugcisa. Incinci kakhulu, iyavuza. Kakhulu, ikhupha ngaphakathi kwaye ingakwazi ukuvala iigalari zeoli okanye i-sensor port-impazamo yentlekele endiyibonile kanye kanye, ekhokelela kwi-injini ebanjwe. Ubungakanani be-bead, imfuno ye-loop eqhubekayo ngaphandle kwekhefu, ixesha lokunyanga ngaphambi kokongeza ulwelo ...

I-Viton gasket ibini. Iyalingana okanye ayifani. Ugxininise izibophelelo ngolandelelwano oluchanekileyo kwi-spec echanekileyo, kwaye ugqibile. Ukungaguquguquki kungenxa yokuba ii-OEMs zisebenzisa irabha ebunjiweyo okanye iigasket zentsimbi naphi na apho kunokwenzeka. Isusa isakhono somsebenzisi kwi-equation. Ukufumana la macandelo achanekileyo kumenzi okhethekileyo kubalulekile. Umzekelo, ukujonga iresource efana https //wwww.ziitasteners.com ayinakuba yeyokuqhobosha kuphela kodwa yokuqonda iinkqubo zokutywina ezo ziqhoboshi ziyacinezela, ziqaqambisa ubume obudityanisiweyo boyilo lwendibano.

Oko kuthethiweyo, i-RTV iyimfuneko kwiindibano ezithile. Xa unesitampu sentsimbi yokudibana kwe-oyile kwibhloko ye-aluminiyam, amazinga okwanda kwe-thermal ayahluka, kwaye umphezulu awufane ube mcaba ngokugqibeleleyo. Igasket eyenziweyo inokuvuza apha. I-bead ye-RTV efanelekileyo ihlala iguquguquka kwaye ivumela ukuba i-micro-movement. Iqhinga kukwazi ukuba yeyiphi imeko okuyo.

Iindleko kunye nexesha lokuphumla: Abaqhubi beSigqibo sokwenyani

Ephepheni, ityhubhu ye-RTV inexabiso eliphantsi kune-gasket ye-Viton yesiko. Kodwa lo ngumgibe. Ixabiso lokwenyani likumjikelezo wobomi obupheleleyo kunye nomngcipheko. Ukuba i-Viton gasket iyasilela, ubuyisela i-gasket. Ukuba isicelo se-RTV asiphumelelanga, uhlala uchitha iiyure ukrazula i-silicone ephilisiweyo kubuso bobabini be-flange-umsebenzi obuhlungu obeka ingozi yokonakalisa indawo-ngaphambi kokuba uphinde ufake isicelo. Iindleko zabasebenzi zinciphisa iindleko zempahla.

Ukulungiswa okukodwa okanye iiprototypes, i-RTV iyamangalisa ngenxa yokuguquguquka kwayo. Kwimveliso okanye inkqubo ebalulekileyo ongafuni ukuyichukumisa kwakhona, tyala imali kwi-gasket eyenziwe ngokufanelekileyo. Ndigcina isitokhwe se-Viton O-rings eqhelekileyo kunye ne-sheet material yokusika i-gaskets yesiko, kodwa ndineentlobo ezintathu ze-RTV kwi-shelf yam. Zizixhobo zemisebenzi eyahlukeneyo.

Ngamanye amaxesha, olona khetho lungcono yi-hybrid. I-bead-on-gasket encinci, echanekileyo apho i-RTV isetyenziswe yi-OEM kwi-carrier gasket ukuqinisekisa ukutywinwa kwiitshaneli ezibalulekileyo. Musa ukuzama ukuphinda oko ngesandla. Ukuba inxalenye yoqobo yayinjalo, yibuyisele ngokufanayo.

Isigwebo sokugqibela: Imalunga nomsebenzi

Ngoko, i-RTV vs. Viton gasket? Yeka ukucinga ngayo njengento echasene nayo. Yimatrix yokukhetha. Buza: Ulwelo? Ubushushu? Uxinzelelo? Ubume bomphezulu? Isekile yomsebenzi? Ukufikeleleka kokusebenza kwakhona?

Ukutywina indlu yempompo yamanzi kwimoto yakudala enemigangatho engafezekanga, ndifikelela kwi-RTV efanelekileyo. Ukutywina i-flange yempompo yamafutha kwi-injini yanamhlanje yokutofa ngokuthe ngqo, ndiyalela i-Viton gasket ethile. Olona khetho lufanelekileyo lolo luhambelana neemfuno ezithile, zomzimba, kunye neekhemikhali zejoyinti eliphambi kwakho, kunye nokuthambekela okunzima ekuthembekeni kwe-gasket eyenziwe kwangaphambili xa zonke ezinye zilingana. Ubulumko abukho ekubambeni ngentloko ii-specs, kodwa ekuqondeni umxholo wetywina. Oko kuvela ekuyenzeni kakubi amaxesha ambalwa, kunye nokufunda ukuba zeziphi iindleko zokucoca.
