Ka ntshetsopele e potlakileng ya othomathiki ya diindasteri, diroboto, dikoloi tse ntjha tsa eneji, le dipalangwang tsa terene, ditlhoko tsa tshebetso bakeng sa thepa ya ho kwahela dithapo di ntse di eketseha. Ka nqane ho ho kwahela ha motlakase wa motheo, dijakete tsa thapo di tlameha ho fana ka kganyetso e ntle ya ho kgohla, kganyetso ya oli, matla a mechini, le ho ikamahanya le maemo a tikoloho ho netefatsa tshebetso e tsitsitseng ya nako e telele maemong a rarahaneng.
Polyamide (PA), e tsejoang haholo e le nylon, e sebelisoa haholo e le thepa ea ho koahela likhoele tsa indasteri, li-harnesses tsa terata tsa likoloi, le likhoele tse khethehileng. Har'a tsona, PA6, PA66, le PA12 ke thepa ea nylon e sebelisoang haholo indastering ea likhoele.
Ke Hobane'ng ha U Sebelisa Nylon ho Cable Sheathing?
Mosebetsi o ka sehloohong oa baki ea cable ke ho sireletsa likarolo tsa ho thibela mocheso le li-conductor tsa kahare ho tsoa tšenyo ea mechini le khatello ea tikoloho. Ha e bapisoa le thepa e kang PVC le PE, nylon e fana ka melemo e 'maloa ea bohlokoa:
E fana ka matla a phahameng a mechini le ho thatafala ha bokaholimo, e ntlafatsa haholo ho hanyetsa ho kgohlopa le tshireletso kgahlanong le tshenyo ya mechini. E boetse e fana ka kganyetso e ntle ho oli e tlotsang, mafura le dikhemikhale tse fapaneng tsa indasteri.
Ho phaella moo, nylon e dumella meralo ya extrusion ya lebota le lesesaane, e thusang ho fokotsa bophara ba cable le boima ka kakaretso ha e ntse e boloka tshebetso ya mechini. Ho hanyetsa ha yona kgatello le ho phunyeha ho etsa hore e lokele ditikoloho tse thata tsa indasteri.
Libakeng tseo ho tsona ho pepesehelang litoeba ho leng bothata, ho thatafala le ho tiea ha nylon ho ka thusa ho fokotsa tšenyo ea mechini e bakoang ke ho loma litoeba; leha ho le joalo, ha ea lokela ho nkoa e le sebaka sa meralo ea cable e inehetseng e hanelang litoeba.
Litšebeliso tse Tloaelehileng tsa Cable tsa Nylon
Moralong oa lithapo, nylon e sebelisoa haholo-holo e le thepa ea sheath e ka ntle.
Bakeng sa lithapo tsa kaho tsa THHN, THWN, le TFFN, hammoho le lithapo tsa elektroniki tsa UL le li-harnesses tse ling tsa lithapo tsa motlakase o tlase tsa likoloi, sebopeho se tloaelehileng ke ho kenya mocheso oa PVC ka jase e tšesaane ea nylon e ka ntle. Moralo ona o ntlafatsa ho khohlela le ho hanyetsa oli ha o ntse o boloka boholo ba thapo e nyane.
Bakeng sa dithapo tsa ketane ya ho hula, dithapo tsa roboto, le dithapo tsa taolo ya indasteri tse hlokang ho kobeha kapa ho sebediswa kgafetsa dibakeng tse thata, sebopeho se kopaneng hangata se sebediswa. Lera le ka hare (PVC, XLPE, kapa TPE) le fana ka ho kwahela le ho tenyetseha, ha lera le ka ntle la nylon le fana ka tshireletso ya mechini, ho hanyetsa ho tsofala, le ho hanyetsa oli.
PA6: Tshebetso e Leka-lekaneng le Bokgoni ba Ditjeo
PA6e fana ka tekano e ntle ea matla a mechini le ho sebetsa habonolo. Ke e 'ngoe ea thepa ea nylon e sebelisoang haholo ka lebaka la melemo ea eona ea litšenyehelo le ts'ebetso e leka-lekaneng.
E sebelisoa hangata ho haha lithapo, likhoele tsa indasteri, le likhoele tse tloaelehileng tsa lithapo tsa likoloi moo ho sa hlokahaleng ho hanyetsa mocheso o feteletseng kapa mongobo.
PA66: Ho Hanela Mocheso o Phahameng le Matla a Mechine
PA66 e na le tekanyo e phahameng ea kristale, e leng se fellang ka ho hanyetsa mocheso hantle, matla a mechini, le ho hanyetsa ho tsofala ha e bapisoa le PA6. E boetse e fana ka khanyetso e ntlafetseng ho oli le mafura.
Mekhoa e tloaelehileng e kenyelletsa terata ea likarolo tsa enjene ea likoloi, likhoele tsa taolo ea indasteri tse mocheso o phahameng, likhoele tsa lipalangoang tsa terene, le libaka tse ling tse hlokang boiteko bo bongata.
PA12: Ho Monyela Mongobo o Tlase le ho Tenyetseha ho Hoholo
PA12e khetholloa ka ho monya mongobo o tlase haholo le ho hanyetsa ha hydrolysis hantle, ho netefatsa thepa e tsitsitseng ea mechini le ea boholo libakeng tse mongobo.
E boetse e fana ka ho tenyetseha ho phahameng ha mocheso o tlase ha ho bapisoa le PA6 le PA66, e leng se etsang hore e lokele likhoele tsa roboto, likhoele tsa ketane ea ho hula, likhoele tsa sensor, le likhoele tse ling tse ikhethang tse hlokang ho tenyetseha ho hoholo le botsitso ba tikoloho.
Nylon e Sireletsang Mollo Litšebelisong tsa Cable
Lisebelisoa tse tloaelehileng tsa nylon ka kakaretso ha li khone ho fihlela litlhoko tsa ho thibela malakabe tsa maemo a cable ka kotloloho. Ka hona, meahong, motlakaseng, lipalangoangng tsa terene le liindastering, ho hlokahala metsoako ea nylon e fetotsoeng e thibelang malakabe.
Ka litsamaiso tse entsoeng hantle tse thibelang malakabe, nylon e ka boloka ts'ebetso ea eona ea mechini ha e ntse e fihlela litlhoko tse amehang tsa tlhahlobo ea malakabe a cable.
Lintlha tsa Bohlokoa Ts'ebetsong ea Nylon Extrusion
Nylon ke thepa e nang le hygroscopic 'me e lokela ho omisoa hantle pele e sebetsoa. Mongobo o feteletseng o ka baka hydrolysis nakong ea ho ntša metsi, e leng se lebisang ho liphoso tsa bokaholimo, ho fokotseha ha thepa ea mechini, le botsitso bo fokolang ba boholo.
Mekhahlelo e fapaneng ea nylon le eona e bontša mekhoa e fapaneng ea ho qhibiliha le ho sebetsa. Ka hona, maemo a ho omisa, liprofaele tsa mocheso oa extrusion, litsamaiso tsa ho pholisa, le lebelo la mela li tlameha ho ntlafatsoa hantle ho latela sehlopha se itseng sa thepa ho netefatsa litekanyo tse tsitsitseng le qetello ea bokaholimo ba boleng bo holimo.
Mokhoa oa ho Khetha Thepa e Nepahetseng ea Nylon
Bakeng sa ho haha lithapo le likhoele tsa indasteri tse akaretsang, PA6 hangata ke khetho e theko e tlaase ka ho fetisisa e nang le ts'ebetso e leka-lekaneng.
Bakeng sa lits'ebetso tse nang le mocheso o phahameng, tse hanelang oli, le tse matla haholo tsa mechini, PA66 hangata e loketse haholoanyane.
Bakeng sa libaka tse mongobo, maemo a mocheso o tlase, le lits'ebetso tse hlokang ho tenyetseha ha nako e telele—joalo ka likhoele tsa roboto, likhoele tsa ketane ea ho hula, le likhoele tse khethehileng—PA12 ka kakaretso e fana ka ts'ebetso e phahameng ka kakaretso.
Qetello
PA6, PA66, le PA12 ka 'ngoe li na le litšobotsi tse ikhethang tsa ts'ebetso, 'me ha ho na thepa e le' ngoe e loketseng lits'ebetso tsohle. Khetho ea thepa e lokela ho ipapisa le tikoloho ea ts'ebetso, litlhoko tsa mechini, maemo a mocheso, litlhoko tsa ho tenyetseha, le lintlha tsa litšenyehelo.
Khetho e nepahetseng ea thepa ea sheathing ea nylon e ka ntlafatsa haholo ho hanyetsa ho taboha ha cable, ho hanyetsa oli le ho tšepahala ha mechini, ha ka nako e ts'oanang ho eketsa nako ea ts'ebeletso le ho fokotsa litšenyehelo tsa tlhokomelo.
Jwalo ka moetsi le mofani ya ka sehloohong wa thepa ya dikheibole Chaena, ONE WORLD e fana ka metswako ya PA6, PA66, le PA12 sheathing bakeng sa dikheibole tsa diindasteri, di-harnesses tsa dithapo tsa dikoloi, dikheibole tsa roboto, le ditshebediso tse ikgethang tsa dikheibole, hammoho le tshehetso ya botekgeniki bakeng sa kgetho ya thepa le ntlafatso ya ditshebediso.
