A na-ejikarị eriri ike polyethylene nke ejiri ihe mkpuchi kpuchie eme ihe n'ọtụtụ ebe n'ime sistemụ ike n'ihi na ọ nwere ezigbo ihe onwunwe okpomọkụ na nke mekaniki, ihe onwunwe eletriki dị mma na iguzogide nchara kemịkalụ. O nwekwara uru nke nhazi dị mfe, ibu dị mfe, ịtọgbọ anaghị ejedebe na mbelata, a na-ejikwa ya nke ọma na grid ike obodo, ebe a na-egwupụta ihe, ụlọ ọrụ kemịkalụ na ihe ndị ọzọ. Ihe mkpuchi nke eriri ahụ na-ejipolyethylene ejikọtara ọnụ, nke a na-agbanwe site na polyethylene molekul nke dị larịị ka ọ bụrụ nhazi netwọk atọ, si otú a na-eme ka njirimara igwe nke polyethylene ka mma nke ukwuu ma na-ejigide njirimara eletriki ya dị mma. Ihe ndị a na-akọwa ọdịiche na uru dị n'etiti eriri polyethylene nke a na-ekpuchi na eriri ndị a na-ekpuchi site n'ọtụtụ akụkụ.
1. Ihe dị iche n'ihe onwunwe
(1) Mgbochi okpomọkụ
Ọkwa okpomọkụ nke waya ndị a na-akpọchi n'ime ihe ndị a na-anaghị ekpuchi na-abụkarị 70°C, ebe ọkwa okpomọkụ nke waya ndị a na-akpọchi n'ime ihe ndị a na-akpọchi n'ime ihe ndị a nwere ike iru 90°C ma ọ bụ karịa, nke na-eme ka ike okpomọkụ nke waya ahụ ka mma nke ukwuu, na-eme ka ọ dabara adaba maka gburugburu ebe ọrụ siri ike karị.
(2) Ike ibu ibu
N'okpuru otu mpaghara nkesa ihe nduzi ahụ, ikike ibugharị eriri XLPE nke a na-etinye n'ime ya dị elu karịa nke eriri mkpuchi nkịtị, nke nwere ike izute sistemụ ọkụ eletrik nwere nnukwu ihe achọrọ maka ọkụ eletrik.
(3) Oke ngwa
Eriri mkpuchi nkịtị ga-ewepụta anwụrụ ọkụ HCl na-egbu egbu mgbe a gbara ya ọkụ, a gaghịkwa eji ya eme ihe n'ọnọdụ ndị chọrọ mgbochi ọkụ gburugburu ebe obibi na obere nsí. Eriri mkpuchi polyethylene ejikọtara ọnụ enweghị halogen, ọ na-adị mma maka gburugburu ebe obibi, ọ dabara adaba maka netwọk nkesa, nrụnye ụlọ ọrụ na ọnọdụ ndị ọzọ chọrọ nnukwu ike ọkụ eletrik, ọkachasị AC 50Hz, voltaji a na-enye ọkwa 6kV ~ 35kV nke enwere ike itinye na eriri nkesa.
(4) Nkwụsi ike nke kemịkalụ
Polyethylene a na-ejikọta ọnụ nwere ezigbo iguzogide kemịkalụ ma nwee ike ịnọgide na-arụ ọrụ nke ọma na gburugburu ebe obibi nke asịd, alkalis na kemịkalụ ndị ọzọ, nke na-eme ka ọ dịkwuo mma maka ojiji na ọnọdụ pụrụ iche dịka osisi kemịkalụ na gburugburu ebe obibi mmiri.
2. Uru nke eriri polyethylene ejikọtara ọnụ
(1) Mgbochi okpomọkụ
A na-agbanwe polyethylene ejiri ihe kemịkalụ ma ọ bụ nke anụ ahụ iji gbanwee nhazi molekul dị larịị ka ọ bụrụ nhazi netwọk atọ, nke na-eme ka iguzogide okpomọkụ nke ihe ahụ ka mma nke ukwuu. Ma e jiri ya tụnyere mkpuchi polyethylene nkịtị na polyvinyl chloride, eriri polyethylene ejiri ihe na-ejikọ ọnụ na-adịgide adịgide karịa na gburugburu okpomọkụ dị elu.
(2) Okpomọkụ ọrụ dị elu
Okpomọkụ ọrụ nke onye na-eduzi ya nwere ike iru 90 Celsius, nke dị elu karịa nke waya PVC ma ọ bụ polyethylene a na-eji eme ihe, si otú a na-eme ka ikike ibugharị eriri ahụ dịkwuo mma nke ukwuu yana nchekwa ọrụ ogologo oge.
(3) Njirimara igwe dị elu
Eriri polyethylene a na-ejigide crosslinked ka nwere ezigbo ihe onwunwe thermo-mechanical na okpomọkụ dị elu, arụmọrụ okpomọkụ ka mma, ma nwee ike ịnọgide na-enwe nkwụsi ike na gburugburu okpomọkụ dị elu ruo ogologo oge.
(4) Ibu dị mfe, nrụnye dị mfe
Ibu nke eriri polyethylene nke ejikọtara ọnụ dị mfe karịa nke waya nkịtị, ebe a na-etinye ya anaghị ejedebe site na mbelata. Ọ dabara nke ọma maka gburugburu ebe owuwu dị mgbagwoju anya na ọnọdụ ntinye eriri buru ibu.
(5) Arụmọrụ gburugburu ebe obibi ka mma:
Eriri polyethylene nke ejiri ihe mkpuchi kpuchie anaghị enwe halogen, ọ naghị ewepụta gas na-egbu egbu n'oge ọkụ, ọ naghị emetụta gburugburu ebe obibi nke ọma, ọ dịkwa mma karịsịa maka ebe ndị nwere ihe achọrọ siri ike maka nchekwa gburugburu ebe obibi.
3. Uru dị na ntinye na mmezi
(1) Ogologo ike dị elu
Eriri polyethylene ejiri crosslinked kpuchie nwere arụmọrụ dị elu nke na-egbochi ịka nká, nke dabara adaba maka itinye ya n'ebe a na-eli ozu ogologo oge ma ọ bụ ikpughe ya n'èzí, na-ebelata ugboro ole a na-eji dochie eriri.
(2) Ntụkwasị obi siri ike nke mkpuchi
Njirimara mkpuchi dị mma nke polyethylene crosslinked, nke nwere nnukwu iguzogide voltaji na ike mmebi, na-ebelata ihe ize ndụ nke ọdịda mkpuchi na ngwa voltaji dị elu.
(3) Ọnụ ego mmezi dị ala
N'ihi iguzogide nchara na nguzogide agadi nke eriri polyethylene a na-etinye n'ime ya, ndụ ọrụ ha na-adịte aka, na-ebelata ụgwọ mmezi kwa ụbọchị na nnọchi.
4. Uru nke nkwado teknụzụ ọhụrụ
N'afọ ndị na-adịbeghị anya, site na mmụba nke teknụzụ ihe polyethylene crosslinked, arụmọrụ mkpuchi ya na ihe onwunwe anụ ahụ emeziwanyela, dịka:
Ihe na-egbochi ire ọkụ emelitere, nwere ike izute ihe achọrọ maka ọkụ ebe pụrụ iche (dịka ụgbọ oloko, ọdụ ọkụ);
Mbelata iguzogide oyi, ka kwụsiri ike na gburugburu ebe oyi na-atụ nke ukwuu;
Site na usoro njikọta ọhụrụ a, usoro mmepụta eriri ahụ na-arụ ọrụ nke ọma ma na-eme ka gburugburu ebe obibi dịkwuo mma.
Site na arụmọrụ ya dị mma, eriri polyethylene a na-ejigide ejikọta na-arụ ọrụ dị mkpa n'ọhịa nke nnyefe na nkesa ike, na-enye nhọrọ nchekwa, ntụkwasị obi karịa na nke na-adịghị ize ndụ maka grid ike obodo ọgbara ọhụrụ na mmepe ụlọ ọrụ mmepụta ihe.
