Sekoti sa cable ke karolo e ka ntle ea mohala.E sebetsa e le mokoallo oa bohlokoa ka ho fetisisa ka mohala ho sireletsa tšireletso ea mohaho oa ka hare le ho sireletsa mohala ho senya mochine nakong le ka mor'a ho kenya.Li-jackets tsa cable ha li reretsoe ho nkela lihlomo tse matlafalitsoeng ka har'a thapo, empa li ka fana ka mokhoa o nepahetseng oa ho itšireletsa, le hoja o lekanyelitsoe.Ho feta moo, lijase tsa cable li sireletsa mongobo, lik'hemik'hale, mahlaseli a UV le ozone.Joale, ke lisebelisoa life tse sebelisetsoang ho roala cable?
1. Lisebelisoa tsa sheath ea cable: PVC
Lisebelisoa tsa cable ke likaroloana tse lokiselitsoeng ka ho kopanya, ho luba le ho ntša polyvinyl chloride e le setsi sa motheo, ho eketsa li-stabilizers, li-plasticizers, li-inorganic fillers tse kang calcium carbonate, li-auxiliary le lubricant.
PVC e ka etsoa hore e sebelisoe libakeng tse fapaneng le lits'ebetsong.E theko e tlaase ho e sebelisa, e tenyetseha, e matla ka mokhoa o utloahalang, 'me e na le lisebelisoa tse thibelang mollo/oli.
Leha ho le joalo, thepa ena e na le lintho tse kotsi tikolohong le 'meleng oa motho,' me ho na le mathata a mangata ha a sebelisoa libakeng tse khethehileng.Ka ntlafatso ea tlhokomeliso ea tikoloho ea batho le ntlafatso ea litlhoko tsa ts'ebetso ea thepa, litlhoko tse phahameng li behiloe pele bakeng sa thepa ea PVC.
2. Lisebelisoa tsa sheath ea cable: PE
Ka lebaka la thepa ea eona e babatsehang ea ho pata motlakase le thepa e ntle ea ho sebetsa, polyethylene e sebelisoa haholo e le lisebelisoa tsa ho roala lithapo le lithapo, 'me e sebelisoa haholo-holo lera la ho kenya letsoho le lera la sheath ea lithapo le likhoele.
Thepa e ntle ea motlakase le khanyetso e phahameng haholo ea insulation.Polyethylene e ka ba thata mme ea thatafala haholo, empa PE (LDPE) e tenyetsehang habonolo ebile e hanyetsana haholo le mongobo.PE e hlophisitsoeng hantle e na le khanyetso e ntle ea boemo ba leholimo.
Sebopeho sa molek'hule sa polyethylene se etsa hore ho be bonolo ho holofala ha mocheso o phahameng.Ka hona, lits'ebetsong tsa PE indastering ea terata le ea lithapo, polyethylene e atisa ho hokahana le sebopeho sa marang-rang, e leng se etsang hore e be e hanyetsanang haholo le mocheso o phahameng.Ho hanana le deformation.
Cross-linked polyethylene (XLPE) le polyvinyl chloride (PVC) ka bobeli li sebelisoa e le lisebelisoa tsa ho koala lithapo le likhoele, empa lithapo le likhoele tsa XLPE li baballa tikoloho ho feta lithapo le likhoele tsa PVC 'me li sebetsa hantle.
3.Cable sheath thepa: PUR
PUR cable ke mofuta o mong oa cable.Thepa ea cable ea PUR e na le melemo ea ho hanyetsa oli le ho hanyetsa ho apara, ha PVC e entsoe ka thepa e tloaelehileng.Ka indasteri ea li-cable lilemong tse 'maloa tse fetileng, polyurethane e se e le ea bohlokoa haholo.Ka mocheso o itseng, thepa ea mochine oa thepa e tšoana le rabara.Ho kopana ha thermoplasticity le elasticity ho fella ka TPE thermoplastic elastomer.
E sebelisoa haholo mecheng ea indasteri le lisebelisoa, litsamaiso tsa taolo ea phetisetso, li-sensor tse fapaneng tsa indasteri, lisebelisoa tsa tlhahlobo, lisebelisoa tsa elektroniki, lisebelisoa tsa ntlo, electromechanical, kichineng le lisebelisoa tse ling, 'me e sebelisetsoa phepelo ea motlakase le likhokahano tsa lipontšo libakeng tse thata, bopaki ba oli. le linako tse ling.
4. Lisebelisoa tsa sheath ea cable: TPE / TPR
Thermoplastic elastomers e fana ka thepa e ntle ea mocheso o tlase ntle le litšenyehelo tsa thermosets.E na le khanyetso e ntle ea lik'hemik'hale le oli 'me e bonolo haholo.Ho hanyetsa ho apara hantle le sebopeho sa bokaholimo, empa ha se tšoarelle joalo ka PUR.
5. Lisebelisoa tsa sheath ea cable: TPU
Mohala oa polyurethane o bua ka thapo e sebelisang thepa ea polyurethane joalo ka sekoaelo kapa sheath.Khanyetso ea eona e kholo ea ho roala e bua ka khanyetso ea super wear ea cable sheath le layer ea insulation.Thepa ea polyurethane e sebelisoang ka likhoele, e tsejoang ka hore ke TPU, ke rabara ea thermoplastic polyurethane elastomer.Haholo-holo e arotsoe ka mofuta oa polyester le polyether, e nang le mefuta e thata (60HA-85HD), ho hanyetsa ho roala, ho hanyetsa oli, ho pepeseha, le elasticity e ntle.TPU ha se feela hore e na le khanyetso e phahameng ea ho sesa, tsitsipano e phahameng, matla a phahameng a ho tsieleha, ho tiea, 'me e na le khanyetso ea botsofali ebile ke thepa e tsoetseng pele e bolokang tikoloho.
Libaka tsa ts'ebeliso ea lithapo tsa polyurethane sheathed li kenyelletsa likhoele tsa ts'ebetso ea metsing, liroboto tsa indasteri le likhoele tsa manipulator, metjhini ea boema-kepe le likhoele tsa meqomo ea gantry crane, le likhoele tsa mochini oa boenjiniere ba merafo.
6. Lisebelisoa tsa sheath ea cable: Thermoplastic CPE
Chlorinated polyethylene (CPE) hangata e sebelisoa libakeng tse thata haholo.E na le litšobotsi tsa boima bo bobebe, e thata haholo, coefficient e tlase ea likhohlano, khanyetso e ntle ea oli, ho hanyetsa metsi hantle, khanyetso e ntle ea lik'hemik'hale le ho hanyetsa UV, le litšenyehelo tse tlase.
7. Lisebelisoa tsa sheath ea cable: rabara ea silicone ea ceramic
Rabara ea silicone ea ceramic e na le tšireletso e ntle ea mollo, e thibelang lelakabe, mosi o tlase, e se nang chefo le thepa e meng.Mokhoa oa ho bopa oa extrusion o bonolo.Masala ka mor'a ho chesa ke khetla e thata ea ceramic.Khetla e thata ha e qhibilihe tikolohong ea mollo ebile ha e theohe, e ka fetisa teko ea botšepehi ba mohala e boletsoeng ho GB/T19216.21-2003 ka mocheso oa 950 ℃-1000 ℃, e pepesehetse mollo ka metsotso e 90, 'me e pholile. metsotso e 15.E loketse sebaka leha e le sefe se hlokang tšireletso ea mollo ho etsa bonnete ba hore phetiso ea matla a boreleli ha ho chesa.E ile ea phetha karolo e tiileng ea tšireletso.
Lihlahisoa tsa rabara tsa silicone tsa ceramic ha li na litlhoko tse khethehileng tsa lisebelisoa le theknoloji ea ho sebetsa e bonolo.Tlhahiso e ka finyelloa ho sebelisoa lisebelisoa tsa khale tsa ho lokisa rabara tsa silicone.Ha e bapisoa le thekenoloji ea morao-rao ea refractory le theknoloji ea tlhahiso ea lithapo, e na le ts'ebetso e phahameng ea tlhahiso 'me e ka fokotsa tšebeliso ea matla a tlhahiso le ho boloka litšenyehelo.
Lintlha tse ka holimo li mabapi le lisebelisoa tsa li-cable sheaths.Ha e le hantle, ho na le mefuta e mengata ea li-cable sheaths.Ha u khetha lisebelisoa tse tala bakeng sa li-cable sheaths, ho lumellana ha sehokelo le ho ikamahanya le maemo ho tlameha ho nahanoa.Mohlala, libaka tse batang haholo li ka hloka hore ho be le li-cable jackets tse lulang li tenyetseha maemong a mocheso a tlase haholo.
