Silane-crosslinked polyethylene (XLPE) cable compounds ke mofuta oa thermoset insulation e sebelisoang lithapong tsa motlakase. Li hlahisoa ke limolek'hule tsa polyethylene tse kopanyang lik'hemik'hale tse sebelisang metsoako ea silane, e fetolang sebopeho sa limolek'hule tsa polyethylene hore e be marang-rang a mararo. Ts'ebetso ena e ntlafatsa botsitso ba mocheso oa thepa, matla a mochini, le thepa ea motlakase, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng, ho tloha ho matla a tlase ho isa ho a phahameng a matla a motlakase ho isa lits'ebetsong tsa likoloi.
Ho etsoa ha lisebelisoa tsa cable tsa silane-crosslinked polyethylene (XLPE) ho tobane le mathata a bohlokoa a tekheniki, ho kenyeletsoa taolo ea pele ho li-crosslinking, optimization ea mocheso oa shrinkage, tokiso ea crystallinity, le botsitso ba ts'ebetso. Likhatelo-pele tsa morao-rao tsa mahlale a thepa le mekhoa ea tlhahiso li sebetsana le litšitiso tsena, 'me li ntlafatsa haholo boleng ba lihlahisoa le lihlahisoa tsa ts'ebetso.
1. Ho Fokotsa Pele ho Phahamisa le Ho Chesa
Phephetso:Ts'ebetsong ea Sioplas, ho pepeseha ha mongobo nakong ea ho kopanya le ho hlahisa likarolo tsa A le B ho ka tsosa karabelo ea hydrolysis le condensation pele ho nako. Sena se etsa hore ho be le li-pre-crosslinking tse sa laoleheng, tse bakang viscosity e phahameng ea ho qhibiliha, phallo e mpe, libaka tse mahlahahlaha, le thepa ea ho kenya letsoho e senyehileng joalo ka motlakase o tlase.
Tharollo:
Khokahanyo ea Matla a Mahlaseli:Ho kenyelletsali-masterbatches tse thehiloeng ho silicone, joalo kaSILIKE's silicone-based processing additiveLYPA-208C, ka katleho e ntlafatsa phallo ea ho qhibiliha, e fokotsa ho khomarela ho qhibiliha ho li-screws le ho shoa, 'me ka katleho e thibela pele ho crosslinking ntle le ho ama boleng ba ho qetela ba ho kopanya.
Keketso ea silicone LYPA-208Ce na le ts'ebetso e matla ea anti-pre-crosslinking ntle le ho ama boleng ba ho qetela ba ho kopanya.
Silicone masterbatch LYPA-208C e tlosa likoli tse holim'a metsi joalo ka "letlalo la shaka" mme e ntlafatsa boreleli ba bokaholimo.
Keketso e thehiloeng ho silicone LYPA-208C e fokotsa haholo torque ea extrusion mme e thibela ho tlala ha koloi.
Li-additives tsa Siloxane LYPA-208Ce matlafatsa botsitso ba mohala oa extrusion le sekhahla sa tlhahiso
Ntlafatso ea Boemo ba Mocheso:Ho kenya tšebetsong lithempereichara tse arohaneng tsa extrusion lipakeng tsa 140°C le 180°C ho thusa ho fokotsa mocheso o feteletseng oa lehae. Ho fokotsa nako ea bolulo libakeng tse nang le mocheso o phahameng ho fokotsa kotsi ea ho kopana pele ho nako
Ts'ebetso ea Mehato e Meli:Ho sebelisa mokhoa oa mehato e 'meli, moo silane e hlomathiseletsoang holim'a polyethylene pele ho extrusion, ho fokotsa likhatello tse amanang le ho kenngoa ha marang-rang, ka tsela eo ho fokotsa monyetla oa ho tšela pele nakong ea extrusion ha e bapisoa le mekhoa ea mohato o le mong.
2. Thermal Shrinkage Performance Optimization
Phephetso:Ho honyela ho feteletseng ha lera ho baka kotsi ea ho holofala ha sebopeho le ho se sebetse hantle ha motlakase, ho amanang le chebahalo ea kristale le matla a pholiso.
Litharollo:
Multi-Stage Cooling Systems:Ho sebelisa tatellano ea mekhahlelo ea ho pholisa metsi a chesang, a futhumetseng le a batang ho liehisa litheko tsa kristale, ho laola ka nepo li-gradients tsa mocheso le ho fokotsa ho honyela.
Phetoho ea Extrusion Parameter: Ho sebelisa li-extruder tse bolelele ba bolelele ho isa ho bophara bo phahameng (≥30:1) ho eketsa nako ea ho boloka qhibidihi, ho hatella kristale e sa batleheng. Ho sebelisa compression ho shoa bakeng sa likhoele tse nyane (≤6mm²) ho fokotsa kristale e hlahisoang ke ho shebana, ho laola ho honyela le ho feta.
Khetho ea Lintho:Ho amohela polyethylene e nang le mehato e 'meli ea silane-crosslinked ho lumella taolo e ntle holim'a boits'oaro ba crystallization, e tlatsetsang ho ntlafatseng botsitso ba mocheso.
3. Ho leka-lekanya Crystallinity le Mechanical Properties
Phephetso:Khanya e phahameng e baka brittleness, ha kristale e sa lekaneng e theola khanyetso ea mocheso.
Litharollo:
Melt Temperature Control:Ho phahamisa mocheso oa ho qhibiliha ho 190 ° C-210 ° C ka nako e telele ea ho lula ho fokotsa kristale nucleation, leha ho le joalo ho hlokahala taolo e hlokolosi ho thibela ho kopana pele ho nako.
Moqapi oa Catalyst Masterbatch:Ho sebelisa li-twin-screw extrusion ho netefatsa phallo e ts'oanang ea li-catalysts tsa organotin, ho ntlafatsa khokahano lipakeng tsa crosslinking le crystallinity ho ntlafatsa thepa ea mochini.
4. Ho Ntlafatsa Tshebetso ea Ts'ebetso
Phephetso:Boikutlo ba ho sebetsana le ho feto-fetoha ha maemo ho baka ho se tsitse ha khatello ea extrusion le ho senyeha ha holimo.
Litharollo:
Lintlafatso tsa Lisebelisoa:Ho kenya ts'ebetsong mekhoa ea ho kopanya li-drum tsa li-drum tse peli ho tiisa hore ho na le ho hasana ho homogeneous ha li-additives tsa silane, ka nako ea ho kopanya e fetang lihora tse 2.5 ho finyella ts'ebetsong e nepahetseng.
Tlhokomelo ea Nako ea 'Nete:Tlhokomelo e tsoelang pele ea screw current le lebelo la ho potoloha e lumella hore ho be le liphetoho tse potlakileng ho litlhophiso tsa mocheso le li-protocol tsa ho hloekisa hlobo, ho boloka maemo a tsitsitseng a ho sebetsa.
Mekhoa ea Indasteri le Pono ea Bokamoso ea tlhahiso ea likhoele tsa XLPE
Ho kopanngoa ha mehato e 'meli ho kopantsoe le li-additives tse sebetsang, tse kang li-silicone-based masterbatches, li hlahile e le leano le ka sehloohong la ho hlōla mathata a ho sebetsana le thepa ea XLPE. Litlhahiso tsena li tlalehoa li ekelitse lihlahisoa tsa tlhahiso ka ho feta 10 ~ 20% lits'ebetsong tsa liteko, ho matlafatsa botšepehi ba likhoele tsa XLPE makaleng a phetiso ea motlakase le likoloi. Ha re shebile pele, bahlahisi ba tsepamisitse maikutlo ho lipatlisiso le nts'etsopele ea mahlale a pholileng a feto-fetohang le taolo e bohlale ea ts'ebetso ho ntlafatsa ts'ebetso ea thepa ea XLPE, ho fihlela tlhoko e ntseng e hola ea likhoele tse sebetsang hantle.
Ka ho amohela maqheka ana a tsoetseng pele a ts'ebetso le lisebelisoa tse ncha, bahlahisi ba ka ntlafatsa haholo ts'ebetso le boleng ba tlhahiso ea cable ea XLPE, ho netefatsa hore ho fanoa ka lihlahisoa tse phahameng tse finyellang litlhoko tse tsoelang pele tsa lisebelisoa tsa motlakase tsa morao-rao.
