Xov xwm

Silane-crosslinked polyethylene (XLPE) cable compounds yog ib hom thermoset rwb thaiv tsev siv hauv hluav taws xob cables. Lawv yog tsim los ntawm chemically crosslinking polyethylene molecules siv silane tebchaw, uas hloov cov linear molecular qauv ntawm polyethylene rau hauv peb-dimensional network. Cov txheej txheem no txhim kho cov khoom siv thermal stability, txhua yam muaj zog, thiab cov khoom siv hluav taws xob, ua rau nws tsim nyog rau ntau yam kev siv, los ntawm qis mus rau high-voltage fais fab kis mus rau hauv tsheb.

Kev sib tw thiab kev daws teeb meem rau silane crosslinked XLPE cable compound cov ntaub ntawv

Kev tsim khoom ntawm silane-crosslinked polyethylene (XLPE) cov ntaub ntawv cable sib txuas ntsib cov teeb meem tseem ceeb, suav nrog kev tswj xyuas ua ntej hla, thermal shrinkage optimization, crystallinity hloov, thiab cov txheej txheem ruaj khov. Kev nce qib tsis ntev los no hauv cov ntaub ntawv tshawb fawb thiab cov txheej txheem tsim khoom yog daws cov teeb meem no, txhim kho cov khoom lag luam zoo thiab ua tiav cov txiaj ntsig.

1. Pre-Crosslinking thiab Scorching Mitigation

 Kev sib tw:Nyob rau hauv cov txheej txheem Sioplas, ya raws thaum lub sij hawm sib tov thiab extrusion ntawm qhov chaw A thiab B tuaj yeem ua rau lub sijhawm ntxov hydrolysis thiab condensation tshwm sim. Qhov no ua rau tsis muaj kev tswj xyuas ua ntej-crosslinking, ua rau ntau dua yaj viscosity, tsis zoo flowability, ntxhib saum npoo, thiab cuam tshuam cov khoom rwb thaiv tsev zoo li qis dua qhov hluav taws xob.

Kev daws:

Lubricant Additive Integration:Kev koom ua kesilicone-raws li masterbatch, zoo liSILIKE's silicone-based processing additiveLYPA-208C, txhim kho cov dej ntws zoo, txo cov yaj adhesion rau cov ntsia hlau thiab tuag, thiab tiv thaiv kev sib tsoo ua ntej yam tsis muaj kev cuam tshuam rau qhov kawg crosslinking zoo.

Silicone additive LYPA-208Cmuaj zog anti-pre-crosslinking kev ua tau zoo yam tsis muaj kev cuam tshuam qhov kawg crosslinking zoo.

Silicone masterbatch LYPA-208C tshem tawm qhov tsis xws luag xws li "shark skin" thiab txhim kho qhov smoothness.

Silicone-based additive LYPA-208C txo qis extrusion torque thiab tiv thaiv lub cev muaj zog tshaj

Siloxane Additives LYPA-208Cboosts extrusion kab stability thiab tso zis npaum li cas

Kub Gradient Optimization:Kev siv segmented extrusion chim kub ntawm 140 ° C thiab 180 ° C pab txo qis hauv zos overheating. Txo lub sij hawm nyob hauv cov cheeb tsam kub siab ntxiv txo qhov kev pheej hmoo ntawm kev sib tshuam ntxov ntxov

Ua ob-kauj ruam:Ua haujlwm ob-kauj ruam txoj kev, qhov twg silane yog grafted rau polyethylene ua ntej extrusion, alleviates lub pressures txuam nrog nyob rau hauv-kab grafting, li no yuav txo tau ntawm pre-crosslinking thaum extrusion piv rau ib kauj ruam mus kom ze.

2. Thermal Shrinkage Performance Optimization

Kev sib tw:Cov txheej txheej rwb thaiv tsev ntau dhau yuav ua rau muaj kev cuam tshuam ntawm cov txheej txheem deformation thiab hluav taws xob tsis ua haujlwm, txuas rau crystalline orientation thiab txias dynamics.

Kev daws:

Multi-Stage Cooling Systems:Siv cov txheej txheem kub, sov, thiab dej txias txias ua rau qeeb qeeb crystallization tus nqi, zoo tswj cov thermal gradients thiab txo qis shrinkage.

Extrusion Parameter Hloov: Siv qhov ntev-rau-ntev piv extruders (≥30: 1) ncua sij hawm yaj tuav, suppressing pliaj crystallization. Kev ua haujlwm compression tuag rau cov cables me me (≤6mm²) txo qis kev taw qhia-induced crystallization, ntxiv tswj shrinkage.

Kev xaiv khoom siv:Kev siv ob-kauj ruam silane-crosslinked polyethylene tso cai rau kev tswj kom zoo dua ntawm kev coj tus cwj pwm crystallization, pab txhawb kev txhim kho thermal stability.

3. Sib npaug Crystallinity thiab Mechanical Properties

Kev sib tw:High crystallinity ua rau brittleness, thaum tsis txaus crystallization undermines thermal kuj.

Kev daws:

Melt Temperature Control:Ua kom cov dej kub nce mus rau 190 ° C-210 ° C nrog lub sijhawm nyob ntev yuav txo tau cov crystal nucleation, tab sis kev tswj xyuas kom zoo yog tsim nyog los tiv thaiv kev sib tshuam ntxov ntxov.

Catalyst Masterbatch Tsim:Siv ntxaib-ntsia hlau extrusion ua kom zoo dispersion ntawm organotin catalysts, optimizing interplay ntawm crosslinking thiab crystallinity los txhim kho txhua yam khoom.

4. Txhim khu kev ruaj ntseg

Kev sib tw:rhiab heev rau cov txheej txheem hloov pauv ua rau extrusion siab instability thiab defects nto.

Kev daws:

Cov khoom siv kho dua tshiab:Kev siv ob lub khob nruas sib xyaw ua ke kom ntseeg tau tias homogeneous dispersion ntawm silane additives, nrog rau kev sib xyaw ntev tshaj li 2.5 teev kom ua tiav qhov zoo sib xws.

Kev saib xyuas lub sijhawm tiag tiag:Kev soj ntsuam tas li ntawm cov ntsia hlau tam sim no thiab kev sib hloov ceev tso cai rau kev hloov kho tam sim rau qhov kub thiab txias thiab pwm ntxuav cov txheej txheem, tswj xyuas kev ua haujlwm ruaj khov.

Kev lag luam Trends thiab yav tom ntej Outlook ntawm XLPE cable manufacturing

Kev sib koom ua ke ntawm ob-kauj ruam ua ua ke nrog cov khoom siv ntxiv, xws li silicone-based masterbatches, tau tshwm sim los ua lub tswv yim ua kom kov yeej cov kev sib tw hauv XLPE cable manufacturing. Cov kev tsim kho tshiab no tau tshaj tawm tias cov khoom lag luam tau nce ntau dua 10 ~ 20% hauv cov ntawv thov kev sim, txhim kho kev ntseeg siab ntawm XLPE cables hauv kev xa hluav taws xob thiab cov khoom siv tsheb. Saib tom ntej, cov tuam txhab lag luam tsom mus rau kev tshawb fawb thiab kev tsim kho cov thev naus laus zis ua kom txias thiab cov txheej txheem ntse tswj kom ua kom zoo dua XLPE cov ntaub ntawv kev ua tau zoo, ua tau raws li qhov kev thov loj hlob rau cov khoom siv hluav taws xob zoo.

Los ntawm kev lees paub cov tswv yim ua tiav qib siab thiab cov khoom siv tshiab, cov tuam ntxhab tuaj yeem txhim kho qhov ua tau zoo thiab zoo ntawm XLPE cable ntau lawm, ua kom cov khoom zoo tshaj plaws uas ua tau raws li qhov xav tau ntawm cov ntawv thov hluav taws xob niaj hnub no.
