Ugbu a, nke a na-ejikarị eme iheihe mkpuchimaka eriri DC bụ polyethylene. Agbanyeghị, ndị na-eme nchọpụta na-aga n'ihu na-achọ ihe mkpuchi mkpuchi nwere ike, dị ka polypropylene (PP). Ka o sina dị, iji PP dị ka ihe mkpuchi eriri USB na-enye ọtụtụ nsogbu.
1. Mechanical Njirimara
Iji mezuo ihe ndị dị mkpa maka njem, nrụnye, na ịrụ ọrụ nke eriri DC, ihe mkpuchi ahụ ga-enwerịrị ike ịrụ ọrụ, gụnyere ezigbo mgbanwe, elongation na nkwụsịtụ, na nguzogide mmetụta dị ala. Otú ọ dị, PP, dị ka nnukwu kristal polymer, na-egosipụta nkwụsi ike n'ime oke okpomọkụ ya na-arụ ọrụ. Na mgbakwunye, ọ na-egosi nhịkọ na ike ịgbawa na gburugburu ebe okpomọkụ dị ala, na-emezughị ọnọdụ ndị a. Ya mere, nyocha ga-elekwasị anya n'ịgbasi ike na imezi PP iji dozie okwu ndị a.
2. Nguzogide ịka nká
N'oge a na-eji ogologo oge eme ihe, mkpuchi eriri DC nke nta nke nta na-eme agadi n'ihi mmetụta jikọtara ọnụ nke oke ọkụ eletrik na ịgba ígwè ọkụ. Nke a ịka nká na-eduga n'ịbelata ihe eji arụ ọrụ na ihe mkpuchi, yana mbelata ike nkwụsịtụ, n'ikpeazụ na-emetụta ntụkwasị obi na ndụ ọrụ nke eriri. Ịka nká mkpuchi eriri USB gụnyere igwe, ọkụ eletrik, akụkụ ọkụ na kemịkalụ, yana ọkụ eletrik na ịka nká bụ ihe kacha emetụta. Ọ bụ ezie na ịgbakwunye antioxidants nwere ike imeziwanye nguzogide PP na ịka nká oxidative ruo n'ókè ụfọdụ, ndakọrịta adịghị mma n'etiti antioxidants na PP, Mbugharị, na adịghị ọcha ha dị ka ihe mgbakwunye na-emetụta arụmọrụ mkpuchi PP. Ya mere, naanị ịdabere na antioxidants iji melite nguzogide ịka nká nke PP enweghị ike izute ogologo ndụ na ihe a pụrụ ịdabere na ya nke mkpuchi USB DC, na-eme ka nyocha ọzọ na-agbanwe PP.
3. Ịrụ ọrụ mkpuchi
Ụgwọ oghere, dị ka otu n'ime ihe ndị na-emetụta àgwà na ndụ nkeeriri DC dị elu, na-emetụta nke ukwuu nkesa ọkụ eletrik mpaghara, ike dielectric, na mkpuchi ihe ịka nká. Ihe mkpuchi maka eriri DC kwesịrị igbochi mkpokọta nke ụgwọ ohere, belata ntụtụ nke ụgwọ oghere oghere dị ka-polarity, ma gbochie ọgbọ nke ụgwọ oghere oghere na-adịghị ka polarity iji gbochie mgbagha ọkụ eletrik n'ime mkpuchi na ihu, na-eme ka ike mgbawa na-emetụtaghị na ogologo ndụ USB.
Mgbe eriri DC na-anọ n'okirikiri eletrọnịkị nke otu ruo ogologo oge, electrons, ion, na ionization adịghị ọcha emepụtara na ihe electrode dị n'ime mkpuchi na-aghọ ụgwọ oghere. Ụgwọ ndị a na-akwaga ngwa ngwa ma na-agbakọta na ngwugwu ụgwọ, nke a maara dị ka mkpokọta nke ụgwọ oghere. Ya mere, mgbe ị na-eji PP na eriri DC, mgbanwe dị mkpa iji gbochie ọgbọ ụgwọ na nchịkọta.
4. Thermal conductivity
N'ihi na-adịghị mma thermal conductivity, okpomọkụ na-emepụta n'oge ọrụ nke PP dabeere na USB cables enweghị ike ịgbasa ngwa ngwa, na-eme ka okpomọkụ dị iche n'etiti n'ime na n'akụkụ akụkụ nke mkpuchi mkpuchi, na-eke na-ezighị ezi okpomọkụ ubi. Igwe ọkụ eletrik nke ihe polymer na-abawanye na oke okpomọkụ. Ya mere, akụkụ dị n'elu nke mkpuchi mkpuchi na obere conductivity na-adị mfe ịnweta mkpokọta, na-eduga n'ibelata ike ọkụ eletrik. Ọzọkwa, gradients okpomọkụ na-eme ka injection na njem nke ọnụ ọgụgụ dị ukwuu nke ụgwọ oghere, na-eme ka ọkụ eletrik na-agbagọ. Ka ọ̀tụ̀tụ̀ okpomọkụ na-adịwanye ukwuu, otú ahụ ka mkpokọta ụgwọ ohere ohere na-apụta, na-eme ka mgbagha ọkụ eletrik dịkwuo elu. Dị ka a tụlere na mbụ, oke okpomọkụ, mkpokọta ụgwọ ohere, na mgbagha ọkụ eletrik na-emetụta ọrụ nkịtị na ndụ ọrụ nke eriri DC. N'ihi ya, imeziwanye conductivity thermal nke PP dị mkpa iji hụ na ọrụ nchekwa na ogologo ndụ ọrụ nke eriri DC.
