I-Silane-crosslinked polyethylene (XLPE) iikhompawundi zentambo luhlobo lwe-thermoset insulation esetyenziswa kwiintambo zombane. Ziveliswa ngeekhemikhali ze-polyethylene ezidibanisa iimolekyuli zisebenzisa iikhompawundi ze-silane, eziguqula umgca we-molecular structure ye-polyethylene ibe yi-network-dimensional network. Le nkqubo iphucula uzinzo thermal eziphathekayo, amandla oomatshini, kunye neempawu zombane, iyenza ilungele izicelo ezahlukeneyo, ukusuka ephantsi ukuya kwi-high-voltage amandla transmission ukuya kwiinkqubo izithuthi.
Ukuveliswa kwe-silane-crosslinked polyethylene (XLPE) izinto zekhebula ezihlangeneyo zijongene nemingeni ebalulekileyo yobugcisa, kubandakanywa nolawulo lwangaphambili lwe-crosslinking, ukulungiswa kwe-thermal shrinkage, ukulungiswa kwe-crystallinity, kunye nokuzinza kwenkqubo. Inkqubela phambili yakutsha nje kwisayensi yezinto kunye neendlela zokuvelisa ilungisa le miqobo, iphucula kakhulu umgangatho wemveliso kunye nokulungiswa kwezivuno.
1. UkuNciphisa i-Pre-Crosslinking kunye ne-Srching
Umngeni:Kwinkqubo yeSioplas, ukuvezwa komswakama ngexesha lokudityaniswa kunye nokukhutshelwa kweSahlulo A kunye ne-B kunokubangela i-hydrolysis yangaphambi kwexesha kunye nokuphendula kwe-condensation. Oku kukhokelela ekudibaneni okungalawulekiyo kwangaphambili, okukhokelela kwi-viscosity ephezulu yokunyibilika, ukuhamba okungahambi kakuhle, indawo erhabaxa, kunye neepropathi zokufakwa esichengeni ezifana nokuncipha kwamandla ombane.
Isisombululo:
ILubricant Additive Integration:Ukudibanisaii-masterbatches ezisekelwe kwi-silicone, njengeSILIKE's abicah-based processing additiveI-LYPA-208C, iphucula ngokufanelekileyo ukuhamba kwe-melt, inciphisa ukunamathela kwi-melt kwi-screws kwaye iyafa, kwaye ikhusela ngokufanelekileyo i-pre-crosslinking ngaphandle kokuchaphazela umgangatho wokugqibela wokuwela.
I-Silicone yokongeza i-LYPA-208Cinomsebenzi onamandla wokuchasana kwangaphambili ngaphandle kokuchaphazela umgangatho wokugqibela wokuwela.
I-Silicone masterbatch LYPA-208C isusa iziphene zomhlaba "njengesikhumba sikakrebe" kwaye iphucula ukuguda komphezulu
I-Silicone-based additive LYPA-208C inciphisa kakhulu i-torque ye-extrusion kwaye ithintele ukugcwala kwemoto
Izongezo zeSiloxane LYPA-208Cinyusa uzinzo lomgca we-extrusion kunye nesantya semveliso
ULungiselelo lweThanga lobushushu:Ukuphumeza i-segmented segmented extrusion barrel amaqondo obushushu phakathi kwe-140°C kunye ne-180°C kunceda ukunciphisa ukufudumeza kwendawo. Ukunciphisa ixesha lokuhlala kwiindawo ezinobushushu obuphezulu kunciphisa ngakumbi umngcipheko wokuphambana kwangaphambi kwexesha
Ukuqhubekekiswa kwamanyathelo amabini:Ukusebenzisa indlela yamanyathelo amabini, apho i-silane ixutywe kwi-polyethylene ngaphambi kokukhutshwa, inciphisa uxinzelelo oluhambelana nokuxhunyelelwa kwi-line, ngaloo ndlela inciphisa amathuba okuba i-crosslinking yangaphambili ngexesha le-extrusion xa kuthelekiswa neendlela zenyathelo elinye.
2. I-Thermal Shrinkage Performance Optimization
Umngeni:Ukucutheka okugqithisileyo kwe-insulation layer kuyingozi kwisakhiwo kunye nokusilela kombane, okunxulunyaniswa nokuqhelaniswa nekristale kunye namandla okupholisa.
Izisombululo:
Iinkqubo zokupholisa zamanqanaba amaninzi:Ukusebenzisa ulandelelwano lwamanqanaba okupholisa amanzi ashushu, ashushu, kunye nabandayo kunciphisa izinga lekristale, ukulawula ngokufanelekileyo i-gradients ezishushu kunye nokunciphisa ukucutheka.
ULungiselelo lweParameter yoHlulo: Ukusebenzisa i-extruders yomlinganiselo ophezulu wobude ukuya ku-diameter (≥30:1) kwandisa ixesha lokugcinwa kwenyibilika, ukucinezela icrystallization engafunekiyo. Ukusetyenziswa koxinzelelo kuyafa kwiintambo ezincinci (≤6mm²) kunciphisa ikristale eyenziwe yiorientation-induced, ilawule ngakumbi ukucutheka.
Ukukhethwa kwezinto:Ukwamkela i-polyethylene enezinyathelo ezimbini ze-silane-crosslinked ivumela ulawulo olungcono malunga nokuziphatha kwe-crystallization, igalelo ekuphuculeni ukuzinza kwe-thermal.
3. Ukulinganisa iCrystallinity kunye neePropati zoomatshini
Umngeni:I-crystallinity ephezulu ibangela ukuba brittleness, ngelixa i-crystallization enganeleyo ijongela ukuxhathisa ukushisa.
Izisombululo:
Nyibilika Ulawulo Lobushushu:Ukuphakamisa amaqondo obushushu okunyibilika ukuya kwi-190 ° C-210 ° C kunye namaxesha okuhlala okwandisiweyo kunciphisa i-crystal nucleation, nangona ukulawulwa ngononophelo kuyimfuneko ukunqanda ukuwela kwangaphambi kwexesha.
Uyilo lweCatalyst Masterbatch:Ukusebenzisa i-twin-screw extrusion kuqinisekisa ukusasazwa okufanayo kwee-organotin catalysts, ukwandisa ukudibanisa phakathi kwe-crosslinking kunye ne-crystallinity ukuphucula iimpawu zoomatshini.
4. Ukuphucula ukuzinza kweNkqubo
Umngeni:Ukuvakalelwa kwinkqubo yokuguquguquka kubangela ukungazinzi koxinzelelo lwe-extrusion kunye neziphene zomhlaba.
Izisombululo:
Uphuculo lweZixhobo:Ukusetyenziswa kweenkqubo zokuxuba i-dual-cone idrum kuqinisekisa ukusasazwa okulinganayo kwezongezo ze-silane, kunye nokuxuba ubude obudlula iiyure ze-2.5 ukuphumeza ukungaguquguquki okulungileyo.
Ukubeka iliso ngexesha lokwenyani:Ukujongwa ngokuqhubekayo kwe-screw yangoku kunye nesantya sokujikeleza kuvumela ukulungiswa ngokukhawuleza kwizicwangciso zeqondo lokushisa kunye neeprothokholi zokucoca i-mold, ukugcina iimeko ezizinzileyo zokucwangcisa.
IiNdlela zoShishino kunye nokuJonga ikamva lokwenziwa kweentambo ze-XLPE
Ukudityaniswa kwamanyathelo amabini adibeneyo kunye nezongezo ezisebenzayo, ezifana ne-silicone-based masterbatches, kuye kwavela njengesicwangciso esikhokelayo sokunqoba imingeni yokucubungula kwi-XLPE yokuvelisa intambo. Olu lutsha luxelwe ukuba lunyuse izivuno zemveliso ngaphezu kwe-10 ~ 20% kwizicelo zokulinga, ukwandisa ukuthembeka kweentambo ze-XLPE kuthutho lwamandla kunye namacandelo eemoto. Ukujonga phambili, abavelisi bagxile kuphando kunye nophuhliso lwetekhnoloji yokupholisa okuguquguqukayo kunye nolawulo lwenkqubo ekrelekrele ukuqhubela phambili ukucokisa ukusebenza kwemathiriyeli ye-XLPE, ukuhlangabezana nemfuno ekhulayo yeentambo ezisebenza kakhulu.
