Iikhompawundi zentambo ze-Silane-crosslinked polyethylene (XLPE) luhlobo lokufakelwa kwe-thermoset olusetyenziswa kwiintambo zombane. Zenziwa ziimolekyuli ze-polyethylene ezidibanisa iikhemikhali zisebenzisa iikhompawundi ze-silane, eziguqula ulwakhiwo lwemolekyuli oluthe ngqo lwe-polyethylene lube yinethiwekhi enamacala amathathu. Le nkqubo iphucula uzinzo lobushushu bezinto, amandla oomatshini, kunye neempawu zombane, okwenza ukuba zilungele ukusetyenziswa ezahlukeneyo, ukusuka ekudlulisweni kwamandla aphantsi ukuya kwaphezulu ukuya kwiinkqubo zeemoto.
Ukuveliswa kwezinto ze-silane-crosslinked polyethylene (XLPE) cable compound materials kujongene nemingeni ebalulekileyo yobugcisa, kubandakanya ulawulo lwe-crosslinking ngaphambi kokuba i-crosslinking iqale, ukulungiswa kokunciphisa ubushushu, ukulungiswa kwekristali, kunye nokuzinza kwenkqubo. Uphuhliso lwakutshanje kwisayensi yezinto kunye neendlela zemveliso lujongana nale miqobo, luphucula kakhulu umgangatho wemveliso kunye nemveliso yokucubungula.
1. Ukunciphisa Ukudibanisa Ngaphambi Kokutsha Nokutsha
Umngeni:Kwinkqubo yeSioplas, ukuvezwa komswakama ngexesha lokuxuba kunye nokukhupha iinxalenye A kunye ne-B kunokubangela i-hydrolysis yangaphambi kwexesha kunye neempendulo zokufuma. Oku kukhokelela ekudibaneni okungalawulwayo kwangaphambili, okubangela i-melt viscosity ephezulu, ukuhamba kakuhle, iindawo ezirhabaxa, kunye neepropati zokuthintela ezibuthathaka ezifana ne-low breakdown voltage.
Isisombululo:
Ukuhlanganiswa kwe-Lubricant Additive:Ukubandakanyaii-masterbatches ezisekelwe kwi-silicone, njengeIsongezelelo sokucubungula esisekelwe kwi-silicone ye-SILIKEI-LYPA-208C, iphucula ukuhamba kokunyibilika ngempumelelo, inciphisa ukunamathela kokunyibilika kwizikrufu kunye nee-die, kwaye ithintela ngempumelelo ukuxhuzulana kwangaphambili ngaphandle kokuchaphazela umgangatho wokugqibela wokuxhuzulana.
Isongezo sesilicone LYPA-208Cinentsebenzo eqinileyo yokulwa nokudibanisa ngaphambi kokudibanisa ngaphandle kokuchaphazela umgangatho wokugqibela wokudibanisa.
I-Silicone masterbatch LYPA-208C isusa iziphene zomphezulu ezifana "nesikhumba sikashaka" kwaye iphucula ukugudiswa komphezulu
Isongezo esisekelwe kwisilicone i-LYPA-208C inciphisa kakhulu i-extrusion torque kwaye ithintela ukuxinana kweemoto
Izongezo zeSiloxane LYPA-208Ckwandisa uzinzo lomgca we-extrusion kunye nezinga lokuphuma
Ukuphuculwa kweGradient yoBushushu:Ukusebenzisa amaqondo obushushu ebharele e-extrusion ahlukeneyo phakathi kwe-140°C kunye ne-180°C kunceda ukunciphisa ubushushu obuphezulu bendawo. Ukunciphisa ixesha lokuhlala kwiindawo ezinobushushu obuphezulu kunciphisa ngakumbi umngcipheko wokuqhagamshelana kwangaphambi kwexesha.
Ukucubungula ngamanyathelo amabini:Ukusebenzisa indlela enamanyathelo amabini, apho i-silane ifakelwa kwi-polyethylene ngaphambi kokuba ikhutshwe, kunciphisa uxinzelelo oluhambelana nokufakelwa kwe-in-line, ngaloo ndlela kunciphisa amathuba okudibanisa kwangaphambili ngexesha lokukhutshwa kwe-extrusion xa kuthelekiswa neendlela ze-single-step.
2. Ukuphuculwa kokusebenza kokuncipha kobushushu
Umngeni:Ukuncipha kakhulu kwe-insulation layer kunokubangela ukuguquguquka kwesakhiwo kunye nokungasebenzi kakuhle kombane, okunxulunyaniswa nokujongwa kwekristale kunye namandla okuphola.
Izisombululo:
Iinkqubo zokuPholisa ezinamanqanaba amaninzi:Ukusebenzisa ulandelelwano lwamanqanaba okupholisa amanzi ashushu, afudumeleyo, nabandayo kucothisa amazinga e-crystallization, kulawula ngempumelelo i-thermal gradients kwaye kunciphise ukuncipha.
Uhlengahlengiso lweParameter ye-Extrusion: Ukusebenzisa ii-extruders ezinobude obuphezulu ukuya kububanzi obuphezulu (≥30:1) kwandisa ixesha lokugcinwa kokunyibilika, kucinezela ukwakheka kwekristale okungafunekiyo. Ukusebenzisa ucinezelo kunciphisa ukwakheka kwekristale okubangelwa kukujongwa, kulawula ngakumbi ukuncipha.
Ukukhetha Izinto:Ukusebenzisa i-polyethylene ene-silane-crosslinked enamanyathelo amabini kuvumela ulawulo olucokisekileyo kwindlela yokwenza i-crystallization, nto leyo enegalelo ekuphuculeni uzinzo lobushushu.
3. Ukulinganisela ubuCristal kunye neeProperties zeMechanical
Umngeni:Ukuqaqamba okuphezulu kwekristali kubangela ukuba buthathaka, ngelixa ukuqaqamba okunganelanga kunciphisa ukumelana nobushushu.
Izisombululo:
Ulawulo lobushushu bokunyibilika:Ukunyusa amaqondo obushushu anyibilikayo ukuya kwi-190°C–210°C kunye nexesha elide lokuhlala kunciphisa i-crystal nucleation, nangona ulawulo olucokisekileyo luyimfuneko ukuthintela ukuqhagamshelana kwangaphambi kwexesha.
Uyilo lweCatalyst Masterbatch:Ukusebenzisa i-extrusion ye-twin-screw kuqinisekisa ukusasazeka okufanayo kwe-organotin catalysts, okuphucula unxibelelwano phakathi kokudibanisa kunye ne-crystallinity ukuphucula iipropati zoomatshini.
