Neoprene vs NBR Rubber Gaskets: Ke Ntho Efe e Lokelang Litlhoko tsa Hao?

Li-gaskets tsa rabara li bapala karolo ea bohlokoa ho tiiseng ha indasteri, ho ama bokhoni ba lisebelisoa tse lutlang, ho hanyetsa mocheso, bophelo ba ts'ebeletso le polokeho. Har'a tsona, li-gaskets tsa rabara tsa neoprene le nitrile ke lisebelisoa tse peli tse tloaelehileng le tse fapaneng tse sebelisoang ho tiisa indasteri. Li bonts'a litšobotsi tse fapaneng tsa ts'ebetso lits'ebetsong tse ngata 'me hangata li bapisoa le lienjineri le batsamaisi ba theko. Ho u thusa ho etsa liqeto tse potlakileng le tse nepahetseng haholoanyane tsa khetho, sengoloa sena se bapisa li-gasket tsa rabara tsa Neoprene le NBR, ho u thusa ho tseba hore na ke lisebelisoa life tse loketseng litlhoko tsa hau.

Sebopeho sa Lintho

Li-gaskets tsa rabara tsa nitrile li entsoe ka copolymer ea butadiene le acrylonitrile (ACN). Litaba tsa ACN li bohlokoa ho khetholla ts'ebetso ea eona:
• Likahare tse phahameng tsa ACN: Ho hanyetsa oli ka matla, empa ho fokotsa ho fetoha ha maemo
• Likahare tse ka tlaase tsa ACN: elasticity e molemo empa ho hanyetsa oli ho fokola
Li-gaskets tsa rabara tsa NBR li loketse ka ho khetheha tikoloho e kenyelletsang oli, mafura, mafura, moholi oa oli le mafura, 'me ke e' ngoe ea lisebelisoa tsa ho tiisa tse sebelisoang haholo mochining le indastering ea likoloi.

Lisebelisoa tsa mantlha

• Sisteme ea mafura a likoloi le ho tiisa ho tiisa ho tlotsa ka mochini
• Ho tiisa tsamaiso ea hydraulic
• Ho tiisa pompo, valve le compressor
• Ho tiisa thepa ea elektronike le ea motlakase

Melemo ea Nitrile Rubber Gaskets

• Ho hanyetsa oli e babatsehang
• Ho hanyetsa ho apara ka holimo le ho hanyetsa ho lla, ho loketse ho tiisa ka matla
• Theko e tlase, e loketse -litheko tse ngata

Li-gaskets tsa rabara tsa Neoprene le NBR li arolelana lintho tse ngata tse tšoanang. Ka bobeli ke li-elastomer tse ntle haholo tse nang le bokhoni bo ka fetoloang, tse khonang ho khutla le ho tlatsa libaka tse sa tloaelehang kamora ho hatella, ho etsa tiiso e tšepahalang. Ka tloaelo li sebetsa ka har'a mocheso o itekanetseng oa likhato tse ka bang -40 ho isa ho 120 degrees . Leha ho le joalo, li fapane haholo likarolong tse ngata tsa ts'ebetso, e leng tsa bohlokoa bakeng sa khetho.

Ho hanyetsa oli

Leha lisebelisoa tsena ka bobeli li hanana le oli-, rabara ea NBR e bontša khanyetso e matla ho mefuta e fapaneng ea oli, ho kenyeletsoa oli ea minerale, peterole, mafura a disele le oli e tlotsang. Neoprene e na le kamano e fokolang le oli. Bakeng sa lits'ebetso tsa ho tiisa tse kenyelletsang ho kopana nako e telele le oli e tlotsang kapa mafura, li-gasket tsa rabara tsa NBR li fana ka ts'ebetso e phahameng ea ho tiisa.

Khanyetso ea Boemo ba Leholimo

Khlorine-e nang le sebopeho le ho tlala ha limolek'hule tsa neoprene li etsa hore e tsitse libakeng tse nang le oxidizing. Sena se lumella li-gasket tsa neoprene ho bonts'a khanyetso ea botsofali ho feta NBR libakeng tse kantle, joalo ka haufi le mabopo a leoatle, moo mahlaseli a UV le maemo a ozone a leng holimo.

Khanyetso ea Lik'hemik'hale

Lihlopha tsa polar tsa NBR li etsa hore e be e tsitsitseng haholoanyane khahlanong le lik'hemik'hale tsa hydrocarbon, empa e sebetsa hampe ka mecha ea litaba e matla ea oxidizing kapa li-solvents tse matla tsa polar. Karolo ea chlorine ho neoprene e ntlafatsa khanyetso ea eona ho li-chloride le li-acid tse fokolang le li-bases, empa ho lumellana ha eona le li-solvents tse itseng kapa lik'hemik'hale tse matla tse senyang li ntse li hloka ho khethoa.

Abrasion le Khanyetso ea Meokho

NBR (rabara ea nitrile) ka kakaretso e feta neoprene (chloroprene rabara) ka bobeli ho hanyetsa abrasion le matla a ho taboha. Li-gaskets tsa NBR tsa rubber li loketse haholoanyane bakeng sa ts'ebetso ea ho tiisa e kenyelletsang{1}}khafetsa e phahameng.

Elasticity le Compression Set

Li-gaskets tsa Neoprene li hlaphoheloa kapele ka mor'a ho hatelloa 'me ha li ratehe ho batalla tlas'a khatello ea nako e telele, li boloka bokhoni ba tsona ba ho tiisa nako e telele. Le hoja NBR e boetse e na le elasticity e ntle, hangata e angoa ke litaba tsa ACN; litaba tse phahameng tsa ACN ka har'a li-gaskets tsa rabara tsa NBR li ka fokotsa matla a tsona.

Litšenyehelo le Botsitso ba Phepelo

Li-gaskets tsa NBR (nitrile rubber) li fana ka litšenyehelo tse tlase le botsitso bo boholo ba phepelo ka lebaka la mehloli e butsoitseng ea lihlahisoa, matla a maholo a tlhahiso ea lefats'e, le mefuta e mengata ea lits'ebetso. Li fumaneha habonolo ka mefuta e fapaneng, ho kenyeletsoa ACN e phahameng, ACN e tlase, -e hananang le oli, le mefuta ea lijo-e leng se etsang hore li tšoanelehe bakeng sa-theko e ngata le litšenyehelo{4}}lisebelisoa tse bobebe moo ho hanyetsa oli e leng tlhokahalo ea mantlha. Ka lehlakoreng le leng, rabara ea Neoprene e na le tekanyo e nyane ea tlhahiso le ho itšetleha haholo ka thepa e itseng e tala, e bakang litheko tse phahameng le ho feto-fetoha ha phepelo ea nako le nako. Boleng ba eona bo itšetlehile haholo ka khanyetso ea boemo ba leholimo, khanyetso ea ozone, botsofali, le ho lieha ha lelakabe, ho etsa hore ts'ebeliso ea eona e shebahale e fapane haholo le ea NBR.

Ho khetha pakeng tsa Neoprene le NBR (Nitrile Rubber) gaskets hase feela taba ea "se molemo ka ho fetisisa," empa ho e-na le ho hlahloba ka botlalo ho itšetlehile ka lintlha tse ngata tse kenyeletsang bohareng, khatello, litlhoko tsa nako ea bophelo, le tekanyetso.

Tšebelisano le Mecha ea litaba

Lisebelisoa tse fapaneng tsa rabara li na le khanyetso e fapaneng haholo le mecha ea litaba e fapaneng.
• Oli, mafura, mafura, li-solvents tsa hydrocarbon: Khetha NBR, kaha sebopeho sa eona se phahameng sa acrylonitrile (ACN) se ntlafatsa haholo ho hanyetsa oli.
• Tikoloho e nang le oxidizing, spray spray, marine air, ozone: Neoprene gaskets lia khothaletsoa ka lebaka la tlhaho ea tsona ea leholimo le ho hanyetsa ozone ho tsoa ho sebopeho sa tsona se nang le chlorine-.
Bakeng sa li-esters tsa maiketsetso, lik'hemik'hale tse senyang, kapa likarolo tse sa tsejoeng, tlhahlobo ea tšebelisano ea laboratori ea hlokahala ho netefatsa hore na ke thepa efe e tšepahalang.

Khetha E Thehiloe ho Mofuta oa ho Tiisa

• Litiiso tse sa fetoheng tse petetsang{0}nako e telele 'me ha li sisinyehe:Li-gaskets tsa Neoprene li na le sete ea khatello e tlase 'me ha li na monyetla oa ho oa ka mor'a ho hatella nako e telele. E loketse li-gaskets tsa flange, litiiso tsa mamati a lisebelisoa, litiiso tsa duct tsa HVAC, le litiiso tsa kantle.
• Litiiso tse matla tse nang le metsamao e feto-fetohang, e bilikang, kapa e sisinyehang:Li-gaskets tsa NBR li fana ka makhopho a matla le ho hanyetsa ho taboha, ho etsa hore li se ke tsa robeha khafetsa tlas'a maemo a ho kuta khafetsa le ho thothomela.

Khetha ho ea ka Lisebelisoa tse Tloaelehileng

Bakeng sa lits'ebetso tse ling tse tloaelehileng, re ka khetha ho latela kutloisiso ea rona ea kopo le ts'ebetso ea lisebelisoa tse peli tsa rabara.
• Tikoloho ea leoatle, HVAC, ho tiisa ka ntle ka ntle: Ho hlokahala khanyetso e phahameng ea leholimo, ho etsa hore li-gaskets tsa Neoprene li be tse loketseng haholoanyane.
• Litsamaiso tsa mafura a likoloi, lienjine, li-compressor: Ho na le litaba tse ngata tse amanang le oli{{0}e thehiloeng ho oli, kahoo li-gaskets tsa NBR tse nang le bothata ba oli li bohlokoa.
• Likhabinete tsa motlakase, litiiso tse sa keneleng mollo: Neoprene e na le ho lieha ho hoholo ha lelakabe ka hona e loketse.
