RTV vs Viton gasket: chisankho chabwino? 

Mukuwona mkanganowu ukukulirakulira nthawi zonse m'mabwalo ndi malo ogulitsira: ndi liti pamene mumagwiritsa ntchito chosindikizira cha RTV motsutsana ndi makina opangidwa kapena opangidwa ndi Viton gasket? Yankho lalifupi ndiloti, palibe. Yankho lalitali ndi pomwe zinthu zimasokonekera, zodula, komanso moona mtima, pomwe anthu ambiri amalakwitsa powatenga ngati zolowa m'malo mwachindunji. Awa ndi mayankho osiyanasiyana amavuto osiyanasiyana.

Kusamvetsetsana Kwambiri: Sealant vs. Gasket

Tiyeni tifotokoze izi poyamba. RTV (Chipinda Chotentha Vulcanizing) silikoni ndi mawonekedwe a gasket. Mumachifinya mu chubu, chimachiritsa mumlengalenga, ndipo chimadzaza mpata. A Viton gasket (FKM fluoroelastomer) ndizopangidwira kale, chigawo cholimba chomwe mumagwetseramo. Cholakwika chachikulu chomwe ndikuwona ndi munthu akugwira RTV chifukwa ndi mofulumira kwa flange yomwe imafunikiradi kuphwanyidwa kolondola ndi kukana kwa mankhwala kwa chidutswa choyenera cha Viton. Ndakhala ndi mlandu wa izi koyambirira, ndikuganiza kuti mkanda wa RTV wotentha kwambiri ukhoza kuyendetsa mzere wamafuta otentha. Sizinalephereke nthawi yomweyo, koma kulira pambuyo pa matenthedwe angapo. Nkhope za flange sizinali zathyathyathya-chinachake chopangidwa ndi gasket chimalipira, koma mkanda wochepa thupi wa RTV sungathe kulumikiza.

Mphamvu za RTV zili m'malo osakhazikika, ntchito zocheperako, kapena komwe muyenera kusindikiza magawo atatu kapena kupitilira apo palimodzi. Ganizirani zivundikiro za ma valve, ma chain chain kesi. Ndi kukhululuka. Mphamvu za Viton ndizodziwika bwino, zopanikizika kwambiri, zotentha kwambiri, kapena m'malo amphamvu amankhwala. Ganizirani machitidwe amafuta, mizere yamafuta a turbocharger, mapampu amphamvu osungunulira. Ndizolondola.

Kusankha nthawi zambiri kumabwera chifukwa cha mawonekedwe a nkhope za flange. Ngati atayidwa, atsekedwa, kapena agwedezeka kupitirira masauzande angapo a inchi, RTV ikhoza kukhala njira yanu yokhayokha popanda makina. Koma ngati muli ndi nkhope zoyera, zosalala, zofananira, gasket yolimba imakhala yabwino nthawi zonse kuti ikhale yodalirika komanso yokhazikika yosindikiza.

Kukaniza Chemical: Kumene Viton Amapeza Zosungirako

Iyi ndiye pulogalamu yakupha ya Viton. Ma silicones a RTV ndi abwino motsutsana ndi madzi, zoziziritsa kukhosi, ndi mafuta ena. Koma yambitsani mafuta (makamaka ophatikiza amakono ndi ethanol), madzi opatsirana, brake fluid, kapena zosungunulira zamphamvu, ndi RTV yokhazikika imasanduka bowa. Pali ma RTV apadera a fluorosilicone, koma ndi okwera mtengo komanso osalimba ngati Viton yolimba.

Ndikukumbukira pulojekiti yokhudzana ndi makina oyesera a biodiesel. Tidagwiritsa ntchito RTV yofiyira yofiira panyumba yamafuta. Pasanathe sabata imodzi, chisindikizocho chinali chitafufuma ndi kufewa, zomwe zinayambitsa kutayikira kwakukulu. Anasinthira ku 75-durometer Viton O-ring yoyenera (sanali ngakhale gasket lathyathyathya) ndipo vutoli linatha kwa zaka zambiri. Mtengo wa gawo la Viton unali wapamwamba, koma nthawi yochepetsera ndi kuyeretsa kuchokera ku RTV yolephera inali khumi. Ndi chuma chabodza chapamwamba.

Yang'anani nthawi zonse ma chart ogwirizana ndi mankhwala. Kwa ma hydrocarbon, aromatics, ndi ma acid, Viton (FKM) nthawi zambiri imakhala yosasinthika. Kwa kampani ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., yomwe imagwira ntchito mu gawo lalikulu lopanga gawo la Yongnian, kusankha njira yosindikiza sikukhudza ntchito ya chomangira komanso kukhulupirika kwa gulu lonse. Amamvetsetsa kuti kutchula chidindo choyenera ndikofunikira monga kufotokozera bawuti yoyenera ya giredi 12.9.

Zowona Zakutentha ndi Kupanikizika

Ma silicones a RTV nthawi zambiri amagulitsidwa ngati kutentha kwambiri, zomwe ndi zoona-ena amatha kunyamula ma spikes apakati mpaka 500 ° F / 260 ° C. Koma ndiye zinthu zochiritsidwa. Chofunika kwambiri ndi kutentha kosalekeza kwa ntchito ndi kupanikizika. Gasket ya Viton imatha kupirira 400 ° F/204 ° C mosalekeza komanso kupanikizika kwambiri chifukwa ndi yokhuthala, yolumikizana ndi elastomer. RTV imapanga khungu ndikuchiritsa mkati, kotero kuti katundu wake wochuluka sakhala wofanana.

Pakukonza kotulutsa mpweya wambiri kwa jenereta, tinayesa RTV yamkuwa yotentha kwambiri pamoto wopindika pang'ono ngati kukonza mwachangu. Idapsa ndikusintha kukhala ufa mkati mwa maola 48 akugwira ntchito mosalekeza. Kutentha kunali kosalekeza komanso kokwera kwambiri, ndi kupalasa njinga. Tidapanga makina a flange ndikugwiritsa ntchito chitsulo chosanjikiza - chilombo chosiyana konse - koma mfundo ndilakuti, ngakhale RTV yotentha kwambiri imakhala ndi zenera lapadera, lomwe nthawi zambiri limayesedwa mopambanitsa.

Pazisindikizo zosasunthika pamakina otentha amafuta (mwachitsanzo, 250 ° F/121 ° C mosalekeza), gasket ya Viton ili m'malo ake otonthoza. RTV kumeneko ikhoza kupulumuka, koma pakapita nthawi, imatha kuumitsa ndikukhala yolimba, kutaya mphamvu yake yosindikiza.

Kugwiritsa Ntchito ndi Feel Factor

Izi ndi zinthu zomwe samayika m'mapepala a data. Kugwiritsa ntchito RTV molondola ndi luso. Pang'ono kwambiri, imatuluka. Mochulukira, imalowa mkati ndipo imatha kuletsa magalasi amafuta kapena ma sensa madoko - cholakwika chachikulu chomwe ndidachiwonapo kamodzi, ndikupangitsa injini yogwidwa. Kukula kwa mikanda, kufunikira kwa kuzungulira kosalekeza popanda kusweka, nthawi yochizira musanawonjezere madzimadzi…

A Viton gasket ndi binary. Zimakwanira kapena ayi. Mumawongolera zomangira motsatira ndondomeko yoyenera, ndipo mwamaliza. Kusasinthika ndichifukwa chake ma OEM amagwiritsa ntchito mphira woumbidwa kapena ma gaskets achitsulo kulikonse kumene kuli kotheka. Imachotsa luso la oyendetsa pa equation. Kupeza zida zolondola izi kuchokera kwa opanga apadera ndikofunikira. Mwachitsanzo, kuyang'ana gwero ngati https://www.zitaifasteners.com Sizingakhale zomangira zokha koma kumvetsetsa makina osindikizira omwe zomangirazo zikukanikizira, kuwunikira mawonekedwe ophatikizika a kapangidwe ka msonkhano.

Izi zati, RTV ndiyofunikira pamisonkhano ina. Mukakhala ndi chitsulo chachitsulo chomangirira poto ku chipika cha aluminiyamu, kuchuluka kwa matenthedwe kumasiyana, ndipo mawonekedwe ake sakhala athyathyathya. Gasket yopangidwa ikhoza kutayikira apa. Mkanda wa RTV yoyenera umakhalabe wosinthika ndipo umakhala ndi kayendedwe kameneka. Chinyengo ndikudziwa momwe mulili.

Mtengo ndi Nthawi Yopuma: Oyendetsa Zosankha Zenizeni

Papepala, chubu cha RTV ndi chotsika mtengo kuposa Viton gasket. Koma ndi msampha. Mtengo weniweni uli m'moyo wonse komanso pachiwopsezo. Ngati Viton gasket ikulephera, mumalowetsa gasket. Ngati ntchito ya RTV ikulephera, nthawi zambiri mumatha maola ambiri mukutsuka silicone yochiritsidwa kuchokera kumaso onse awiri - ntchito yomvetsa chisoni yomwe imawononga malo - musanagwiritsenso ntchito. Mtengo wa anthu ogwira ntchito umacheperapo mtengo wa zinthu.

Pakukonzanso kamodzi kapena ma prototypes, RTV ndiyabwino kusinthasintha kwake. Pakupanga kapena dongosolo lovuta lomwe simukufuna kukhudzanso, ikani ndalama mu gasket yopangidwa yoyenera. Ndimakhala ndi zida za Viton O-ring ndi mapepala odula ma gaskets, koma ndilinso ndi mitundu itatu ya RTV pa alumali yanga. Ndi zida za ntchito zosiyanasiyana.

Nthawi zina, kusankha bwino ndi haibridi. Kachilombo kakang'ono, kolondola komwe RTV imayikidwa ndi OEM pa chonyamulira gasket kuti zitsimikizire zosindikizira mumayendedwe ovuta. Musayese kubwereza izo ndi dzanja. Ngati gawo loyambirira linali lotero, m'malo mwake lisinthe ndi lomwelo.

Chigamulo Chomaliza: Ndi Ponena za Ntchito

Ndiye, RTV vs. Viton gasket? Siyani kuganiza motsutsa. Ndi matrix osankhidwa. Funsani: Madzi? Kutentha? Kupanikizika? Mkhalidwe wapamtunda? Ntchito yozungulira? Kupezeka kwa rework?

Kuti ndisindikize nyumba yopopera madzi pagalimoto yapamwamba yokhala ndi malo opanda ungwiro, ndikufika pa RTV yoyenera. Kuti ndisindikize chopopera chamafuta pa injini yamakono yojambulira mwachindunji, ndikuyitanitsa Viton gasket. Chisankho chabwino kwambiri ndi chomwe chikugwirizana ndi zofunikira zenizeni, zakuthupi, ndi mankhwala a olowa patsogolo panu, ndi kukondera kwakukulu kwa kudalirika kwa gasket yopangidwa kale pamene zina zonse ziri zofanana. Nzeru siziri pakuloweza mfundo, koma pozindikira tanthauzo la chisindikizocho. Izi zimabwera chifukwa cholakwitsa kangapo, ndikuphunzira momwe kuyeretsa kumawonongera.
