Yintoni i-Chlorinated Polyethylene (cpe) kwaye isetyenziswa phi?
I-Argonated polyethylene cpe low density polyethylene 2 i-silicone yerabha edityanisiweyo ye-cable insulation material is low density polyethylene (LDPE) kunye ne-polydimethylsiloxane ehambelana ne-ethyl methacrylate (EMA) (PDMS) umxube werabha yimathiriyeli esebenzayo yokugquma ikhebula. Iipropati ezahlukeneyo zombane, iipropati zomatshini kunye neepropati zokushisa zomxube zafundwa. Iziphumo zibonisa ukuba ukudibanisa kunokusetyenziswa njengento yokufakelwa kwe-Thermal, xa kuthelekiswa nempahla yerubha ye-silicone, ineendleko ezingcono zokusebenza.
Kwangexesha elide, abantu baye bathatha irabha ye-silicone njengerabha ekhethekileyo yeentambo kuluhlu olubanzi lwamaqondo aphezulu kunye namaqondo aphantsi. Nangona kunjalo, ixabiso elibizileyo lerabha ye-silicone linciphisa uluhlu lwesicelo sayo.
I-LDPE yiplastiki enesona sixa sikhulu kushishino. Inexabiso eliphantsi kunye neepropati zombane ezigqwesileyo, ngoko ke isetyenziswa ngokubanzi njengepolymer ekhuselayo kwiingcingo zombane ophakathi naphantsi kunye neentambo. I-LDPE ayiphelelanga nje kwixabiso eliphantsi kodwa ikwakwiqondo eliphantsi le-dielectric engaguqukiyo kunye nelahleko, ukuxhathisa okuphezulu, kunye neempawu ezibalaseleyo zoomatshini ngaphantsi kweqondo lobushushu le-90C, ngoko ke uninzi lweerubha ezenziweyo, njengerabha ye-styrene-butadiene (SBR), irabha yebutyl (IR ), neoprene(CR) njalo njalo baphulukene nenxalenye yesabelo semarike. Xa kuthelekiswa nezinto zokugquma irabha ye-silicone, umxube we-polydimethylsiloxane (PDMS) kunye ne-LDPE inenzuzo yeendleko eziphantsi ukwenzela ukuhlangabezana namabakala ahlukeneyo, Ukongeza kwiimfuno ezikhethekileyo zeentambo zokuhambisa amandla, ukulawula kunye nezixhobo, abantu baye baqhubeka bephuhlisa. izixhobo ezahlukeneyo zokugquma iipolymer ezintsha. Nangona kunjalo, iipropati zomatshini kunye nokumelana nobushushu benkqubo yombane ephantsi-voltage (<10kV) imathiriyeli iphezulu kune
Iimpawu zombane zibaluleke ngakumbi.
Umzekelo; i-cable insulation layer yesithando somlilo kufuneka ibe nokuzinza okulungileyo kweempawu zomatshini kwiqondo lokushisa eliphezulu. Ngokufanayo; iimfuno zeentambo zomsi ophantsi, ezinganyangekiyo kwioli, kunye neentambo ezikwaziyo ukumelana nomlilo nazo zahlukile. Ngoko intambo kufuneka Isiganeko sesicelo simisela iimfuno zokusebenza okukhethekileyo kwentambo. Ukuchithwa kwe-oxidative ye-rubber kunye nokwakhiwa kwe-oxide layer phezu komhlaba kuya kwandisa ukuhanjiswa, kuba emva kokuba i-rubber i-oxidized, i-polarity yenziwa phakathi kwee-carbon black aggregates.
Amaqela (afana ne-carboxyl) La maqela abonelela ngendlela emfutshane yee-electron. Kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha imathiriyeli yesicelo. Ngokubhekiselele kwi-cable insulation; iparameter ebalulekileyo yayo Imida ukukwazi kwangoku ukudlula kwi-insulation layer. Ngokwangoku ngokuthe ngqo (dc), kuyacaca ukuba ukusetyenziswa kwezinto ezinokumelana okuphezulu kunokunciphisa ubuninzi be-insulation layer; kutshintshiselwano lwangoku (ac), imvume enxulumene nelahleko isezantsi noko.
I-Disipation factor iphinda inciphise ubukhulu be-insulation.
I-Ethyl methacrylate (EMA) inokutshintshwa kakhulu yirubha ye-silicone njengesixhobo sokugquma usebenzisa i-PDMS yokudibanisa kwiimpawu ezahlukeneyo zombane, iipropati zomatshini kunye nokumelana nokushisa.
Ukusebenza kwexabiso elifanayo njenge-compatibilizer ye-LDPE kunye ne-PDMSA imixube (50:50).
1. Inkqubo yokukhusela ezinzileyo, i-CPE iya kukhulula i-hydrogen chloride xa ishushu okanye i-vulcanized, ngoko ke i-stabilizers ene-acid absorption effect kufuneka isetyenziswe kwifomula, njenge-calcium stearate, i-barium stearate, i-tribasic lead sulfate okanye i-magnesium oxide.
2. Inkqubo yePlastiki. Iiplastiki ze-Ester zisetyenziswa ngokuqhelekileyo kwi-CPEZ, njenge-dioctyl phthalate (DOP) kunye ne-dioctyl adipate (DOA). Iiparamitha zabo zokunyibilika zisondele kwezo zeCM. Umthamo olungileyo. Ukusetyenziswa kwe-DOA kunye ne-DOS kwirabha kunokunika irabha ngokuxhathisa okugqwesileyo okubandayo.
3. Inkqubo ye-vulcanization ye-CPE, i-CPE i-rubber egcweleyo, kwaye inkqubo ye-sulfur vulcanization eqhelekileyo ayikwazi ukuyiphazamisa ngokufanelekileyo. Ukusetyenziswa kokuqala kwenkqubo ye-CPE ye-vulcanization yinkqubo ye-thiourea, eyona nto isebenzayo yi-Na-22, kodwa i-Na-22 inesantya esicothayo se-vulcanization, ukusebenza kakubi kokuguga, isethi yoxinzelelo oluphezulu, kunye ne-Na-22 yi-carcinogen eyingozi. Ivelisa iphunga elingathandekiyo, kwaye ukusetyenziswa kwayo kunqatshelwe ngaphandle.
4. Ukuqiniswa kwenkqubo yokuzalisa, i-CPE luhlobo lwerubha olungenakuziqinisa, olufuna inkqubo yokuqinisa ukufezekisa amandla angcono. Inkqubo yokuzaliswa kwayo yokuqinisa ifana ne-adhesive-njongo ye-adhesive. I-arhente yokuqinisa ubukhulu becala yi-carbon emnyama kunye ne-carbon black black. Ikhabhoni emhlophe emnyama inokuphucula ukuxhathisa kweenyembezi ze-CPE, kwaye inokwenza inkqubo emhlophe ye-metamethyl ukuphucula ukunamathela phakathi kwe-CPE kunye ne-skeleton. dibanisa. I-CPE inepropathi ephezulu yokuzalisa, kwaye inkqubo yokuzalisa ikakhulu ibandakanya i-calcium carbonate, i-talcum powder, udongwe, njl.
