Chlorinated Polyethylene (cpe) ke Eng 'me E sebelisoa Hokae?
Argonated polyethylene cpe low density polyethylene 2 silicone rubber blend cable insulation material is low density polyethylene (LDPE) le polydimethylsiloxane e tsamaisanang le ethyl methacrylate (EMA) (PDMS) (PDMS) motsoako oa rabara ke sesebelisoa se sebetsang se sa keneleng mocheso.Mefuta e sa tšoaneng ea motlakase, thepa ea mechine le thepa ea mocheso ea motsoako e ile ea ithutoa.Liphetho li bonts'a hore motsoako o ka sebelisoa e le thepa ea ho kenya mocheso, ha e bapisoa le thepa ea rabara ea silicone, e na le ts'ebetso e ntle ea litšenyehelo.
Ka nako e telele, batho ba 'nile ba nka rabara ea silicone e le rabara e khethehileng bakeng sa likhoele ka mefuta e mengata ea mocheso o phahameng le o tlaase.Leha ho le joalo, theko e theko e boima ea rabara ea silicone e lekanyetsa mefuta ea ts'ebeliso ea eona.
LDPE ke polasetiki e nang le palo e kholo ka ho fetisisa indastering.E na le theko e tlase ebile e na le thepa e ntle ea motlakase, ka hona e sebelisoa haholo joalo ka polymer e sireletsang lithapo le likhoele tse mahareng le tse tlase.LDPE ha e theko e tlase feela empa e boetse e na le "dielectric" e tlase le ntlha ea tahlehelo, e phahameng ea resistivity, le lisebelisoa tse ntle tsa mochini tse ka tlase ho mocheso o ka tlase ho 90C, kahoo liraba tse ngata tsa maiketsetso, joalo ka rabara ea styrene-butadiene (SBR), butyl rabara (IR) ), neoprene(CR) joalo-joalo ba lahlehetsoe ke karolo ea 'maraka.Ha ho bapisoa le thepa ea ho kenya rabara ea silicone, motsoako oa polydimethylsiloxane (PDMS) le LDPE o na le molemo oa litšenyehelo tse tlaase bakeng sa ho finyella litekanyetso tse fapaneng, Ho phaella litlhoko tse khethehileng tsa likhoele bakeng sa phetisetso ea matla, taolo le lisebelisoa, batho ba 'nile ba tsoela pele ho ntlafatsa. lisebelisoa tse fapaneng tse ncha tsa polymer insulation.Leha ho le joalo, thepa ea mochini le ho hanyetsa mocheso oa lisebelisoa tsa motlakase oa motlakase o tlase (<10kV) li phahame ho feta
Lintho tsa motlakase li bohlokoa ho feta.
Ka mohlala;sebono sa cable bakeng sa sebōpi se lokela ho ba le botsitso bo botle ba thepa ea mochine mocheso o phahameng.Ka mokhoa o ts'oanang;ditlhoko tsa mehala e sa tsubeng haholo, e thibelang oli, le e thibelang malakabe le tsona li fapane.Kahoo thapo e lokela Ketsahalo ea kopo e etsa qeto ea litlhoko tsa ts'ebetso e khethehileng ea thapo.Ho senyeha ha oxidative ea rabara le ho thehoa ha lesela la oxide holim'a metsi ho tla eketsa conductivity, hobane ka mor'a hore rabara e be le oxidized, polarity e hlahisoa pakeng tsa carbon black aggregates.
Lihlopha (joaloka carboxyl) Lihlopha tsena li fana ka tsela e khuts'oane ea lielektrone.Ho na le lintlha tse 'maloa tse lokelang ho nahanoa ha u khetha lisebelisoa bakeng sa kopo.Mabapi le ho insulation cable;parameter ea bohlokoa ke Meeli ea eona ea bokhoni ba hona joale ba ho feta ka lera la insulation.Bakeng sa hona joale ka ho toba (dc), ho totobetse hore tšebeliso ea lisebelisoa tse phahameng tsa ho hanyetsa li ka fokotsa botenya ba lera la ho pata;bakeng sa alternating current (ac), tumello le tahlehelo e lekanyelitsoeng e batla e le tlase.
Dissipation factor e boetse e fokotsa botenya ba insulation.
Ethyl methacrylate (EMA) e ka nkeloa sebaka haholo ke rabara ea silicone e le thepa ea ho kenya letsoho e sebelisang motsoako oa PDMS bakeng sa thepa e fapaneng ea motlakase, thepa ea mochini le ho hanyetsa mocheso.
Katleho ea chelete e lekanang le e tsamaisanang le LDPE le PDMSA e kopanya (50:50).
1. Sistimi e tsitsitseng ea ts'ireletso, CPE e tla lokolla hydrogen chloride ha e futhumala kapa e chesoa, kahoo li-stabilizers tse nang le phello ea ho monya acid li lokela ho sebelisoa ka foromo, joalo ka calcium stearate, barium stearate, tribasic lead sulfate kapa magnesium oxide.
2. Plasticizing tsamaiso.Li-plasticizers tsa Ester li sebelisoa hangata ho CPEZ, joalo ka dioctyl phthalate (DOP) le dioctyl adipate (DOA).Mekhahlelo ea bona ea solubility e haufi le ea CM.Bokhoni bo botle.Tšebeliso ea DOA le DOS ka rabara e ka etsa hore rabara e be le khanyetso e ntle ea serame.
3. Sistimi ea vulcanization ea CPE, CPE ke rabara e tletseng, 'me mokhoa o tloaelehileng oa vulcanization oa sebabole o ke ke oa o senya ka katleho.Tšebeliso ea pele ea tsamaiso ea CPE vulcanization ke tsamaiso ea thiourea, e sebetsang ka ho fetisisa ea Na-22, empa Na-22 e na le lebelo le fokolang la vulcanization, ts'ebetso e mpe ea botsofali, sete e phahameng ea khatello, 'me Na-22 ke kankere e tebileng.E hlahisa monko o sa thabiseng, 'me tšebeliso ea eona e thibetsoe linaheng tse ling.
4.
