Ndị na-emepụta ọkpọkọ epoxy na-ewebata ihe ndị a nkọwa nke mkpuchi ihe
Dị ka ọkọlọtọ mba GB2900.5 si kwuo, nkọwa nke ihe mkpuchi bụ: “ihe eji ekpuchi ngwaọrụ eletrik”. Ya bụ, ihe mkpuchi nke na-egbochi ụzọ ọkụ eletrik. Nguzogide ya dị oke elu, na-adịkarị n’ogo nke 10-10Ω·m. Dị ka ọ dị n’ime moto, ihe mkpuchi mkpuchi gburugburu ndị na-eduzi na-ekewapụ ntụgharị na site na stator core nke ala iji hụ na arụ ọrụ nke moto ahụ dị mma.
A na-akpọ ihe ndị mejupụtara ihe ndị nwere ihe mgbochi nke 109 ruo 1022 Ω•Cm ihe mkpuchi na teknụzụ eletrik, nke a makwaara dị ka dielectrics. N’ikwu ya n’ụzọ dị mfe, ọ bụ ihe na-ekewapụ anụ ahụ ebubo n’akụkụ ndị ọzọ. Ihe mkpuchi mkpuchi nwere nnukwu nguzogide DC ugbu a. N’okpuru arụ ọrụ nke voltaji DC, ọ fọrọ nke nta ka ọ bụrụ anaghị arụ ọrụ ma e wezụga maka obere ntapu elu dị ugbu a. Maka AC ugbu a, enwere capacitive ugbu a na-agafe, mana a na-ewerekwa ya ka ọ naghị eme ya. Na-eduzi. Ihe dị elu nke resistivity nke ihe mkpuchi ahụ, nke ka mma na-arụ ọrụ mkpuchi.
Na teknụzụ ọkụ eletrik, ihe mkpuchi na-ezokarị aka na ihe nwere resistivity karịrị 10 ruo 9th Ω.cm. Ọrụ nke ihe mkpuchi ihe bụ nkewapụ akụkụ ndụ nke ikike dị iche iche na ngwa eletriki.
Ya mere, ihe mkpuchi mkpuchi ga-enwerịrị ezigbo ihe dielectric, ya bụ, ha ga-enwerịrị ihe mkpuchi mkpuchi dị elu na ike mkpakọ, ma nwee ike izere ihe mberede dị ka ntanye, creepage na mmebi; Nke abuo, nguzogide okpomọkụ nke ihe mkpuchi mkpuchi ka mma, tumadi na Ọ na-ekwe nkwa na a gaghị enwe mgbanwe arụmọrụ n’ihi ikpo ọkụ ogologo oge; na mgbakwunye, ọ nwere ezigbo conductivity thermal, mmiri na-eguzogide, ike igwe dị elu, na nhazi dị mma.
Enwere ike kewaa ihe mkpuchi mkpuchi nke ndị ọkụ eletrik na-ejikarị n’ime ihe ndị na-emepụta ihe na ihe ndị na-emepụta ihe dịka ụdị kemịkal dị iche iche si dị. Enwere ụdị ihe mkpuchi mkpuchi atọ na ihe mkpuchi agwakọta.
