Izindaba

Izinhlanganisela zekhebula le-Silane-crosslinked polyethylene (XLPE) ziwuhlobo lwe-thermoset insulation esetshenziswa ezintanjeni zikagesi. Akhiqizwa ngamamolekyuli e-polyethylene anqamula ngamakhemikhali esebenzisa izinhlanganisela ze-silane, eziguqula umugqa wesakhiwo samangqamuzana e-polyethylene sibe inethiwekhi enezinhlangothi ezintathu. Le nqubo ithuthukisa ukuzinza kwe-thermal, amandla emishini, kanye nezakhiwo zikagesi, iyenze ifanelekele izinhlelo zokusebenza ezihlukahlukene, kusukela ekudluliselweni kwamandla aphansi ukuya ku-high-voltage kuya kumasistimu ezimoto.

Kucutshungulwa izinselelo nezisombululo ze-silane crosslinked XLPE cable compound materials

Ukukhiqizwa kwezinto ezihlanganisiwe zekhebula le-silane-crosslinked polyethylene (XLPE) kubhekene nezinselele zobuchwepheshe ezibucayi, okuhlanganisa nokulawula ukuxhumanisa kwangaphambi kokuphambana, ukwenza ngcono ukushwabana kwe-thermal, ukulungiswa kwecrystallinity, nokuzinza kwenqubo. Intuthuko yakamuva yesayensi yezinto ezibonakalayo kanye nezindlela zokukhiqiza ibhekana nalezi zithiyo, ithuthukisa kakhulu ikhwalithi yomkhiqizo kanye nesivuno sokucubungula.

1. Ukunciphisa Ngaphambi Kwe-Crosslinking kanye Nokushisa

 Inselelo:Enqubweni ye-Sioplas, ukuchayeka komswakama ngesikhathi sokuxutshwa nokukhishwa kwezingxenye A no-B kungadala i-hydrolysis ngaphambi kwesikhathi kanye nokusabela kokujiya. Lokhu kuholela ekuxhumaneni okungalawuleki kwangaphambi kokuphambana, okuholela ekuncibilikeni okuphezulu, ukugeleza okungekuhle, izindawo ezimahhadlahhadla, kanye nezakhiwo zokufakwa ebucayini ezifana nokwehla kwamandla kagesi.

Isixazululo:

I-Lubricant Additive Integration:Iyahlanganisaama-masterbatches asekelwe ku-silicone, njengeIsengezo sokucubungula esenziwe nge-silicone sika-SILIKEI-LYPA-208C, ithuthukisa ngempumelelo ukugeleza kokuncibilika, inciphisa ukunamathela kokuncibilika kuzikulufu futhi ife, futhi ivimbele ngempumelelo ukuphambana kwangaphambili ngaphandle kokuthinta ikhwalithi yokugcina yokuphambana.

Isengezo se-Silicone i-LYPA-208Cinokusebenza okuqinile kwe-anti-pre-crosslinking ngaphandle kokuthinta ikhwalithi yokugcina yokuxhumanisa.

I-Silicone masterbatch LYPA-208C iqeda ukukhubazeka okungaphezulu "njengesikhumba sikashaka" futhi ithuthukisa ukushelela kwendawo

Isengezo esenziwe nge-silicone i-LYPA-208C sehlisa kakhulu i-torque ye-extrusion futhi sivimbele ukugcwala kwemoto

I-Siloxane Additives LYPA-208Cikhuphula ukuzinza komugqa we-extrusion kanye nezinga lokuphumayo

Ukuthuthukiswa Kwezinga Lezinga lokushisa:Ukusebenzisa amazinga okushisa emiphongo ye-extrusion ehlukanisiwe phakathi kuka-140°C no-180°C kusiza ukunciphisa ukushisa okweqile kwendawo. Ukunciphisa isikhathi sokuhlala ezindaweni ezinezinga lokushisa eliphezulu kwehlisa futhi ingcuphe yokuphambana ngaphambi kwesikhathi

Ukucubungula okuzinyathelo ezimbili:Ukusebenzisa indlela yezinyathelo ezimbili, lapho i-silane ixhunyelelwa ku-polyethylene ngaphambi kokukhishwa, kunciphisa izingcindezi ezihambisana nokuxhunyelelwa emgqeni, ngaleyo ndlela kunciphisa amathuba okuphambana kwangaphambili ngesikhathi sokukhipha uma kuqhathaniswa nezindlela zesinyathelo esisodwa.

2. Ukuthuthukiswa Kokusebenza Kwe-Thermal Shrinkage

Inselelo:Ukuncipha kwesendlalelo sokufakelwa ngokweqile kuyingozi ekuwohlokeni kwesakhiwo kanye nokwehluleka kukagesi, okuxhunywe ku-crystalline orientation namandla okupholisa.

Izixazululo:

Amasistimu wokupholisa wezigaba eziningi:Ukusebenzisa ukulandelana kwezigaba zokupholisa amanzi ashisayo, afudumele, nabandayo kwehlisa izinga lokucwebezela, ukulawula kahle ukuthambeka okushisayo nokunciphisa ukushwabana.

Ukulungiswa Kwepharamitha Ye-Extrusion: Ukusebenzisa ama-extruder esilinganiso sobude ukuya kububanzi obuphezulu (≥30:1) kunweba isikhathi sokugcinwa kwencibilika, kucindezela ukucwebezela okungafuneki. Ukusebenzisa ukuminyanisa kuyafa kumakhebuli amancane (≤6mm²) kunciphisa ukucwebezela okubangelwa ukuma, kuqhubeke nokulawula ukuncipha.

Ukukhetha Okubalulekile:Ukwamukela i-polyethylene enezinyathelo ezimbili ze-silane-crosslinked kuvumela ukulawula okucolisekileyo phezu kokuziphatha kwe-crystallization, okunikela ekuthuthukisweni kokuqina okushisayo.

3. Ukulinganisa i-Crystallinity kanye ne-Mechanical Properties

Inselelo:Ukucwebezela okuphezulu kubangela ukonakala, kuyilapho ukucwebezela okwanele kwehlisa ukumelana nokushisa.

Izixazululo:

I-Melt Temperature Control:Ukuphakamisa izinga lokushisa elincibilikayo liye ku-190°C–210°C ngezikhathi zokuhlala ezinwetshiwe kunciphisa i-crystal nucleation, nakuba ukuphathwa ngokucophelela kuyadingeka ukuze kuvinjelwe ukuphambana ngaphambi kwesikhathi.

I-Catalyst Masterbatch Design:Ukusebenzisa i-twin-screw extrusion kuqinisekisa ukuhlakazeka okufanayo kwama-catalysts e-organotin, kuthuthukisa ukusebenzisana phakathi kokuphambana nokucwebezela ukuze kuthuthukiswe izici zokushintshwa.

4. Ukuthuthukisa Ukuzinza Kwenqubo

Inselelo:Ukuzwela ukucubungula ukuguquguquka kubangela ukungazinzi kwengcindezi ye-extrusion kanye nokukhubazeka kwendawo.

Izixazululo:

Ukuthuthukiswa Kwezisetshenziswa:Ukusebenzisa izinhlelo zokuhlanganisa imigqomo ye-dual-cone kuqinisekisa ukuhlakazeka okulinganayo kwezithasiselo ze-silane, ubude besikhathi sokuxuba obungaphezu kwamahora angu-2.5 ukuze kuzuzwe ukuvumelana okuphelele.

Ukuqapha Kwesikhathi Sangempela:Ukuqapha okuqhubekayo kwe-screw current kanye nesivinini sokujikeleza kuvumela ukulungiswa okusheshayo kuzilungiselelo zokushisa kanye nezivumelwano zokuhlanza isikhunta, ukugcina izimo zokucubungula ezizinzile.

Amathrendi embonini kanye ne-Outlook Yekusasa yokwenziwa kwamakhebula e-XLPE

Ukuhlanganiswa kokucutshungulwa kwezinyathelo ezimbili kuhlanganiswe nezithasiselo ezisebenzayo, ezifana ne-silicone-based masterbatches, kuvele njengesu eliholayo lokunqoba izinselele zokucubungula ekukhiqizeni amakhebula e-XLPE. Lokhu kuqanjwa kubikwa ukuthi kwenyuse umkhiqizo wokukhiqiza ngaphezu kuka-10~20% ezinhlelweni zokuhlola, okuthuthukisa ukwethembeka kwezintambo ze-XLPE emikhakheni yokudluliswa kwamandla nezimoto. Uma sibheka phambili, abakhiqizi bagxile ocwaningweni nasekuthuthukisweni kobuchwepheshe bokupholisa obuvumelana nezimo kanye nezilawuli zenqubo ezihlakaniphile ukuze kuthuthukiswe ukusebenza kwempahla ye-XLPE, ukuhlangabezana nesidingo esikhulayo samakhebuli asebenza kahle kakhulu.

Ngokwamukela lawa maqhinga athuthukisiwe okucubungula kanye nokuqanjwa kwezinto ezibonakalayo, abakhiqizi bangathuthukisa kakhulu ukusebenza kahle kanye nekhwalithi yokukhiqizwa kwekhebula le-XLPE, baqinisekise ukulethwa kwemikhiqizo ephakeme ehlangabezana nezidingo eziguqukayo zezinhlelo zokusebenza zikagesi zesimanje.
