Silane-crosslinked polyethylene (XLPE) cable compounds ndi mtundu wa thermoset insulation yomwe imagwiritsidwa ntchito mu zingwe zamagetsi. Amapangidwa ndi ma molekyulu a polyethylene omwe amaphatikizika ndi mankhwala a silane, omwe amasintha ma cell a polyethylene kukhala maukonde amitundu itatu. Njirayi imapangitsa kuti zinthuzo zikhale zokhazikika, mphamvu zamakina, ndi mphamvu zamagetsi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana, kuchokera kutsika mpaka kumtunda wamagetsi amagetsi kupita ku machitidwe a magalimoto.

Kukonza zovuta ndi mayankho a silane crosslinked XLPE cable compound materials

Kupanga zida za silane-crosslinked polyethylene (XLPE) zimayang'anizana ndi zovuta zaukadaulo, kuphatikiza kuwongolera kusanachitike, kukhathamiritsa kwamafuta, kusintha kwa crystallinity, komanso kukhazikika kwazinthu. Kupita patsogolo kwaposachedwa kwa sayansi ya zinthu ndi njira zopangira zikuthana ndi zopingazi, kuwongolera kwambiri zokolola zazinthu ndi kukonza zokolola.

1. Pre-Crosslinking ndi Kuchepetsa Kutentha

 Chovuta:Munjira ya Sioplas, kuwonekera kwa chinyezi pakuphatikiza ndi kutulutsa Magawo A ndi B kumatha kuyambitsa hydrolysis isanakwane komanso kuyanika. Izi zimapangitsa kuti pakhale kusakanikirana kosalamulirika, zomwe zimapangitsa kusungunuka kwamphamvu kwambiri, kusayenda bwino, malo owoneka bwino, komanso kuwonongeka kwa zinthu zotsekereza monga magetsi otsika.

Yankho:

Lubricant Additive Integration:Kuphatikizazitsulo zopangidwa ndi silicone, mongaSILIKE's silicone-based processing additiveLYPA-208C, imathandizira bwino kusungunuka kwamadzi, imachepetsa kumamatira ku zomangira ndikufa, ndipo imateteza bwino kuphatikizika popanda kukhudza mtundu womaliza wolumikizana.

Silicone zowonjezera LYPA-208Cili ndi machitidwe amphamvu odana ndi pre-crosslinking popanda kukhudza mtundu womaliza wolumikizana.

Silicone masterbatch LYPA-208C imachotsa zofooka zapamtunda ngati "khungu la shaki" ndikuwonjezera kusalala kwa pamwamba.

Silicone-based additive LYPA-208C imachepetsa kwambiri torque ya extrusion ndikuletsa kuchulukira kwa magalimoto.

Zowonjezera za Siloxane LYPA-208Cimawonjezera kukhazikika kwa mzere wa extrusion ndi kuchuluka kwa zotulutsa

Kukonzekera kwa Temperature Gradient:Kugwiritsa ntchito magawo ang'onoang'ono a kutentha kwa migolo yapakati pa 140 ° C ndi 180 ° C kumathandiza kuchepetsa kutenthedwa kwapadera. Kuchepetsa nthawi yokhala m'malo otentha kwambiri kumachepetsanso chiopsezo cha kuphatikizika msanga

Kukonza Njira ziwiri:Kugwiritsa ntchito njira ziwiri, pomwe silane imamezeredwa pa polyethylene isanatulutsidwe, imachepetsa zovuta zomwe zimagwirizanitsidwa ndi kulumikiza pamzere, potero kuchepetsa mwayi wodutsanapo panthawi ya extrusion poyerekeza ndi njira imodzi yokha.

2. Thermal Shrinkage Performance Optimization

Chovuta:Kuchulukitsitsa kwambiri kwa kusanjikiza kosanjikiza kumawononga kuwonongeka kwamapangidwe ndi kulephera kwamagetsi, komwe kumalumikizidwa ndi mawonekedwe a crystalline ndi kuzizira kwamphamvu.

Zothetsera:

Multi-Stage Cooling Systems:Kugwiritsa ntchito njira zoziziritsira madzi otentha, otentha, ndi ozizira kumachepetsa kuchuluka kwa makristali, kuwongolera bwino kutentha komanso kuchepetsa kuchepa.

Kusintha kwa Parameter Extrusion: Kugwiritsa ntchito zotulutsa zazitali zazitali mpaka m'mimba mwake (≥30:1) kumakulitsa nthawi yosungunuka yosungunuka, kupondereza kristalo wosafunikira. Kugwiritsa ntchito kukanikiza kumafa pazingwe zing'onozing'ono (≤6mm²) kumachepetsa kuyika kwa makristalo, ndikuwongoleranso kuchepa.

Zosankha:Kutenga masitepe awiri a silane-crosslinked polyethylene kumalola kuwongolera bwino pamachitidwe a crystallization, zomwe zimathandizira kukhazikika kwamafuta.

3. Kuyanjanitsa Crystallinity ndi Mechanical Properties

Chovuta:Kuwala kwambiri kumayambitsa brittleness, pomwe kusakwanira kwa crystallization kumachepetsa kukana kwamafuta.

Zothetsera:

Melt Temperature Control:Kukweza kutentha kosungunuka kufika 190 ° C-210 ° C ndi nthawi yotalikirapo yokhazikika kumachepetsa nucleation ya kristalo, ngakhale kuyang'anira mosamala ndikofunikira kuti mupewe kuphatikizika msanga.

Catalyst Masterbatch Design:Kugwiritsa ntchito ma twin-screw extrusion kumatsimikizira kubalalitsidwa kofanana kwa zothandizira za organotin, kukhathamiritsa kuyanjana pakati pa crosslinking ndi crystallinity kupititsa patsogolo makina.

4. Kupititsa patsogolo Kukhazikika kwa Njira

Chovuta:Kumverera kwa kusintha kusinthasintha kumayambitsa kusakhazikika kwa kuthamanga kwa extrusion ndi kuwonongeka kwa pamwamba.

Zothetsera:

Zowonjezera Zida:Kugwiritsa ntchito makina osakanikirana a ng'oma yapawiri-cone kumawonetsetsa kubalalitsidwa kofanana kwa zowonjezera za silane, ndi nthawi yosakanikirana yopitilira maola 2.5 kuti mukwaniritse kusasinthika koyenera.

Kuwunika Nthawi Yeniyeni:Kuwunika kosalekeza kwa wononga pakali pano ndi liwiro lozungulira kumathandizira kusintha mwachangu kutengera kutentha ndi ma protocol otsuka nkhungu, kukhalabe ndi zinthu zokhazikika.

Mawonekedwe a Viwanda ndi Tsogolo la Kupanga Zingwe za XLPE

Kuphatikizika kwa masitepe awiri ophatikizika ndi zowonjezera zogwira ntchito, monga silicone-based masterbatches, kwatuluka ngati njira yopambana yothanirana ndi zovuta pakukonza zingwe za XLPE. Zatsopanozi akuti zachulukitsa zokolola ndi kupitilira 10-20% pakugwiritsa ntchito oyendetsa, kupititsa patsogolo kudalirika kwa zingwe za XLPE pamagawo otumizira magetsi ndi magalimoto. Kuyang'ana m'tsogolo, opanga akuyang'ana kwambiri kafukufuku ndi chitukuko cha matekinoloje ozizirira osinthika komanso njira zowongolera mwanzeru kuti apititse patsogolo magwiridwe antchito a XLPE, kukwaniritsa kufunikira kwa zingwe zogwira ntchito kwambiri.

Pogwiritsa ntchito njira zapamwambazi zogwirira ntchito komanso zatsopano zakuthupi, opanga amatha kupititsa patsogolo mphamvu ndi khalidwe la kupanga zingwe za XLPE, kuonetsetsa kuti kuperekedwa kwa zinthu zapamwamba zomwe zikugwirizana ndi zomwe zikufunikira pamagetsi amakono.
