Silane-crosslinked polyethylene (XLPE) cable compounds imhando ye thermoset insulation inoshandiswa mumatambo emagetsi. Iwo anogadzirwa nekemikari crosslinking polyethylene mamorekuru achishandisa silane makomisheni, ayo anoshandura mutsara wemamorekuru chimiro che polyethylene kuita matatu-dimensional network. Iyi nzira inokwidziridza kugadzikana kwemafuta, simba remagetsi, uye zvinhu zvemagetsi, zvichiita kuti ive yakakodzera kune akasiyana maapplication, kubva pasi kusvika kune yakakwira-voltage simba rekufambisa kune mota masisitimu.
Kugadzirisa zvinonetsa uye zvigadziriso zve silane crosslinked XLPE tambo yemubatanidzwa zvinhu
Kugadzirwa kwe silane-crosslinked polyethylene (XLPE) tambo yakasanganiswa zvinhu zvinotarisana nematambudziko akakosha ehunyanzvi, anosanganisira pre-crosslinking control, thermal shrinkage optimization, crystallinity kugadzirisa, uye process kugadzikana. Kufambira mberi kuchangobva kuitika musainzi yezvinhu uye nzira dzekugadzira dziri kugadzirisa zvipingaidzo izvi, zvakanyanya kuvandudza mhando yechigadzirwa uye kugadzirisa goho.
1. Pre-Crosslinking uye Scorching Mitigation
Dambudziko:Mukuita kweSioplas, kuratidzwa kwemwando panguva yekusanganisa uye kubuda kweZvikamu A uye B kunogona kukonzeresa nguva isati yakwana hydrolysis uye condensation maitiro. Izvi zvinotungamira kune isingadzoreki pre-crosslinking, zvichikonzera yakakwira kunyunguduka viscosity, kuyerera kwakashata, nzvimbo dzakashama, uye kukanganisa kuvharidzira zvivakwa senge yakaderera breakdown voltage.
Solution:
Lubricant Additive Integration:Incorporatingsilicone-based masterbatches, zvakaita seSILIKE's silicone-based processing additiveLYPA-208C, inonyatso kunatsiridza kunyungudika kuyerera, inoderedza kunyunguduka kunamatira kune screws uye kufa, uye zvinodzivirira kudzivirira pre-crosslinking pasina kukanganisa yekupedzisira crosslinking mhando.
Silicone additive LYPA-208Cine yakasimba anti-pre-crosslinking performance isina kukanganisa yekupedzisira crosslinking mhando.
Silicone masterbatch LYPA-208C inobvisa kuremara kwepasi se "shark ganda" uye inosimudzira kutsvedzereka kwepasi.
Silicone-based additive LYPA-208C inoderedza zvakanyanya extrusion torque uye inodzivirira mota kuwandisa.
Siloxane Additives LYPA-208Cinowedzera extrusion line kugadzikana uye chiyero chekubuda
Temperature Gradient Optimization:Kuisa tembiricha yakakamurwa extrusion barrel iri pakati pe140°C ne180°C kunobatsira kuderedza kupisa kwenzvimbo. Kuderedza nguva yekugara munzvimbo dzekupisa kwepamusoro kunowedzera kudzikisira njodzi yekukurumidza kuyambuka
Matanho maviri Kugadziridza:Kushandisa nzira mbiri-nhanho, apo silane inobatanidzwa pa polyethylene isati yasvika, inoderedza kudzvinyirirwa kunobatanidza ne-in-line grafting, nokudaro kuderedza mukana we pre-crosslinking panguva ye extrusion kana ichienzaniswa nenhanho imwe chete nzira.
2. Thermal Shrinkage Performance Optimization
Dambudziko:Yakawandisa insulation layer shrinkage ine njodzi deformation uye kutadza kwemagetsi, kwakabatana nekristaro kutaridzika uye kutonhora simba.
Mhinduro:
Multi-Stage Cooling Systems:Kushandisa nhevedzano yemvura inopisa, inodziya, uye inotonhora yekutonhodza nhanho inononoka kristalllization rates, kunyatso gadzirisa kupisa kwemafuta uye kuderedza kuderera.
Extrusion Parameter Kugadziriswa: Kushandisa kureba-kusvika-dhayamita reshiyo extruders (≥30:1) inowedzera kunyunguduka kuchengetedza nguva, kudzvanyirira kusingadiwe crystallization. Kushandisa kudzvanya kunofira tambo diki (≤6mm²) kunoderedza kutarisisa-induced crystallization, zvichiwedzera kudzora kuderera.
Kusarudzwa kwezvinhu:Kutora maviri-nhanho silane-crosslinked polyethylene inobvumira kudzora kwakatsetseka pamusoro pekristalllization maitiro, zvichibatsira mukuvandudza kugadzikana kwekupisa.
3. Kuenzanisa Crystallinity uye Mechanical Properties
Dambudziko:Yakakwira crystallinity inokonzeresa brittleness, nepo kusakwana kwecrystallization kunodzikisira kupisa kwekupisa.
Mhinduro:
Melt Temperature Control:Kukwidza tembiricha yekunyungudika kusvika 190°C–210°C nekurebesa nguva dzekugara kunoderedza kristaro nucleation, kunyange hazvo manejimendi akangwarira anodiwa kudzivirira kuyambuka nguva isati yakwana.
Catalyst Masterbatch Dhizaini:Kushandisa mapatya-screw extrusion inovimbisa kupararira kwakafanana kweiyo organotin catalysts, optimize kupindirana pakati pekuchinjika uye crystallinity kuti uwedzere michina zvivakwa.
4. Kuwedzera Kugadzikana Kwemaitiro
Dambudziko:Sensitivity yekugadzirisa kuchinja kunokonzera extrusion pressure kusagadzikana uye kukanganisa kwepamusoro.
Mhinduro:
Equipment Upgrades:Kushandisa maviri-cone madhiramu ekusanganisa masisitimu anovimbisa kupararira kwakafanana kwe silane additives, nekusanganisa nguva inopfuura 2.5 maawa kuti uwane yakakwana kuenderana.
Real-Time Monitoring:Kuenderera mberi kwekutarisa screw ikozvino uye kutenderera kumhanya kunobvumira kukurumidza kugadzirisa kune tembiricha marongero uye mold yekuchenesa mapuroteni, kuchengetedza yakagadzikana yekugadzirisa mamiriro.
Indasitiri Maitiro uye Ramangwana Maonero eXLPE tambo yekugadzira
Iko kubatanidzwa kwematanho maviri ekugadzirisa akasanganiswa neanoshanda ekuwedzera, akadai sesilicone-based masterbatches, yabuda senzira inotungamira yekukunda matambudziko ekugadzirisa mukugadzira tambo yeXLPE. Aya magadzirirwo anonzi akawedzera goho rekugadzira neinopfuura gumi ~ 20% mumapilot application, zvichiwedzera kuvimbika kwetambo dzeXLPE mukufambisa kwemagetsi uye zvikamu zvemotokari. Tichitarisa kumberi, vagadziri vari kutarisa nezvekutsvaga nekuvandudza tekinoroji yekutonhodza tekinoroji uye nehungwaru maitiro ekutonga kuti aenderere mberi nekunatsa XLPE kuita kwezvinhu, kusangana nekukura kuri kudiwa kwetambo dzepamusoro-soro.
Nekugamuchira aya epamberi ekugadzirisa hurongwa uye hunyanzvi hwezvinhu, vagadziri vanogona kusimudzira zvakanyanya kushanda uye kunaka kweXLPE tambo yekugadzira, kuve nechokwadi chekuunzwa kwezvigadzirwa zvepamusoro zvinosangana nezvinoda kubuda zvemazuva ano mashandisirwo emagetsi.
