Ma waya a polyethylene olumikizidwa ndi silane (XLPE) ndi mtundu wa thermoset insulation yomwe imagwiritsidwa ntchito mu zingwe zamagetsi. Amapangidwa ndi mamolekyu a polyethylene olumikizana ndi mankhwala pogwiritsa ntchito mamolekyu a silane, omwe amasintha kapangidwe ka molekyulu ya polyethylene kukhala netiweki ya magawo atatu. Njirayi imawonjezera kukhazikika kwa kutentha kwa chinthucho, mphamvu ya makina, ndi mphamvu zamagetsi, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito zosiyanasiyana, kuyambira kutumiza mphamvu zochepa mpaka zamagetsi ambiri kupita ku makina a magalimoto.

Mavuto ndi mayankho a zinthu zolumikizidwa ndi chingwe cha XLPE cha silane

Kupanga zipangizo za silane-crosslinked polyethylene (XLPE) cable compound kumakumana ndi mavuto akuluakulu aukadaulo, kuphatikizapo kuwongolera pre-crosslinking, kukonza thermal shrinkage, kusintha crystallinity, ndi kukhazikika kwa njira. Kupita patsogolo kwaposachedwa mu sayansi ya zinthu ndi njira zopangira kukuthetsa mavutowa, kukweza kwambiri khalidwe la zinthu ndi zokolola zokonzedwa.

1. Kuchepetsa Kulumikizana ndi Kuwotcha Asanayambe

 Vuto:Mu njira ya Sioplas, kukhudzana ndi chinyezi panthawi yosakaniza ndi kutulutsa kwa Gawo A ndi B kungayambitse hydrolysis isanafike nthawi yogwira ntchito komanso condensation reactions. Izi zimapangitsa kuti pakhale kusalumikizana kosalamulirika, zomwe zimapangitsa kuti kusungunuka kukhale kwakukulu, kuyenda bwino, malo osasunthika, komanso zinthu zoteteza kutentha zikhale zovuta monga kuchepa kwa magetsi.

Yankho:

Kuphatikiza Kowonjezera Mafuta:Kuphatikizama masterbatches opangidwa ndi silikoni, mongaChowonjezera cha SILIKE chopangidwa ndi siliconeLYPA-208C, imawongolera bwino kayendedwe ka kusungunuka, imachepetsa kuuma kwa kusungunuka ku zomangira ndi kufa, ndipo imaletsa bwino kusakanikirana koyambirira popanda kusokoneza mtundu womaliza wa kusakanikirana.

Chowonjezera cha silikoni LYPA-208CIli ndi mphamvu yolimbana ndi kulumikiza koyambirira popanda kusokoneza ubwino wa kulumikiza komaliza.

Silicone masterbatch LYPA-208C imachotsa zolakwika pamwamba monga "khungu la shaki" ndipo imawonjezera kusalala pamwamba.

Chowonjezera chopangidwa ndi silicone LYPA-208C chimachepetsa kwambiri mphamvu ya extrusion ndipo chimaletsa kuchuluka kwa injini

Zowonjezera za Siloxane LYPA-208Ckumawonjezera kukhazikika kwa mzere wotulutsa ndi kuchuluka kwa zotuluka

Kukonza Magiredi Otentha:Kugwiritsa ntchito kutentha kwa mbiya yotulutsa mpweya m'magawo pakati pa 140°C ndi 180°C kumathandiza kuchepetsa kutentha kwambiri komwe kumachitika m'malo ena. Kuchepetsa nthawi yokhala m'malo otentha kwambiri kumachepetsanso chiopsezo cha kulumikizana msanga.

Kukonza kwa Masitepe Awiri:Kugwiritsa ntchito njira ya magawo awiri, pomwe silane imalumikizidwa pa polyethylene isanatulutsidwe, kumachepetsa kupsinjika komwe kumachitika chifukwa cha kulumikizidwa mu mzere, motero kuchepetsa mwayi wolumikizana musanayambe kupangidwa poyerekeza ndi njira imodzi.

2. Kukonza Magwiridwe Abwino a Kutentha kwa Kutentha

Vuto:Kuchepa kwambiri kwa zigawo zotetezera kutentha kungayambitse kusintha kwa kapangidwe kake ndi kulephera kwa magetsi, zomwe zimagwirizanitsidwa ndi kayendedwe ka kristalo ndi mphamvu zoziziritsira.

Mayankho:

Machitidwe Oziziritsira a Masitepe Ambiri:Kugwiritsa ntchito njira zosiyanasiyana zoziziritsira madzi otentha, ofunda, ndi ozizira kumachepetsa kuchuluka kwa makristalo, kumayang'anira bwino kutentha kwa dzuwa ndikuchepetsa kuchepa kwa madzi.

Kusintha kwa Ma Parameter OwonjezeraKugwiritsa ntchito zotulutsira ma crystals aatali kwambiri (≥30:1) kumawonjezera nthawi yosungira madzi, kuletsa ma crystallization osafunikira. Kugwiritsa ntchito compression kumathandizira ma crystallization ang'onoang'ono (≤6mm²) kumachepetsa ma crystallization omwe amayambitsidwa ndi njira yolunjika, ndikuwonjezera kuchepera.

Kusankha Zinthu:Kugwiritsa ntchito polyethylene yolumikizidwa ndi silane yokhala ndi magawo awiri kumathandiza kuti pakhale kuwongolera bwino momwe makristalo amagwirira ntchito, zomwe zimathandiza kuti kutentha kukhazikike bwino.

3. Kulinganiza Makhalidwe a Khiristo ndi Makina

Vuto:Kuchuluka kwa makristalo kumayambitsa kufooka, pomwe kusakwanira kwa makristalo kumachepetsa kukana kutentha.

Mayankho:

Kulamulira Kutentha kwa Sungunulani:Kukweza kutentha kwa kusungunuka kufika pa 190°C–210°C ndi nthawi yayitali yokhazikika kumachepetsa kupangika kwa makristalo, ngakhale kuyang'aniridwa mosamala ndikofunikira kuti tipewe kulumikizana msanga.

Kapangidwe ka Catalyst Masterbatch:Kugwiritsa ntchito extrusion ya twin-screw kumaonetsetsa kuti ma catalyst a organotin amafalikira mofanana, zomwe zimapangitsa kuti mgwirizano pakati pa crosslinking ndi crystallinity ukhale wabwino kwambiri kuti uwonjezere mphamvu zamakina.

4. Kulimbitsa Kukhazikika kwa Njira

Vuto:Kuzindikira kusinthasintha kwa njira zogwirira ntchito kumayambitsa kusakhazikika kwa kuthamanga kwa mpweya komanso zolakwika pamwamba.

Mayankho:

Kukweza Zida:Kugwiritsa ntchito njira zosakaniza ng'oma za cone ziwiri kumatsimikizira kufalikira kwa zinthu zowonjezera za silane molingana, ndipo nthawi yosakaniza imapitirira maola 2.5 kuti pakhale kukhazikika bwino.

Kuwunika Nthawi Yeniyeni:Kuyang'anira kosalekeza kwa mphamvu ya screw ndi liwiro lozungulira kumathandiza kusintha mwachangu kutentha ndi njira zotsukira nkhungu, zomwe zimapangitsa kuti zinthu zizikhala bwino.

Zochitika Zamakampani ndi Malingaliro Amtsogolo Pakupanga Zingwe za XLPE

Kuphatikiza kwa njira ziwiri zopangira zinthu pamodzi ndi zowonjezera, monga silicone-based masterbatches, kwakhala njira yotsogola yothanirana ndi mavuto opangira zinthu pakupanga zingwe za XLPE. Zatsopanozi zikunenedwa kuti zawonjezera zokolola zopanga ndi zoposa 10-20% mu ntchito zoyeserera, zomwe zawonjezera kudalirika kwa zingwe za XLPE m'magawo otumizira magetsi ndi magalimoto. Poyang'ana mtsogolo, opanga akuyang'ana kwambiri kafukufuku ndi chitukuko cha ukadaulo wozizira wosinthika komanso zowongolera zanzeru kuti akonze bwino magwiridwe antchito a zida za XLPE, kukwaniritsa kufunikira kwakukulu kwa zingwe zogwira ntchito kwambiri.

Mwa kuvomereza njira zamakono zopangira zinthu komanso zatsopano, opanga amatha kupititsa patsogolo kwambiri magwiridwe antchito ndi mtundu wa kupanga zingwe za XLPE, ndikuwonetsetsa kuti zinthu zabwino kwambiri zomwe zikugwirizana ndi zosowa zamakono zamagetsi.
