Plastiki iconductor here kana kuti insulator?Chekutanga, ngatinzwisise mutsauko uripo pakati pezviviri izvi: Kondakita chinhu chine diki redziviriro uye chinoitisa magetsi nyore.Insulator chinhu chisingafambisi magetsi mumamiriro ezvinhu akajairika.Hunhu hwema insulators ndehwekuti machaji akanaka uye asina kunaka mumamorekuru akasungwa zvakasimba, uye kune mashoma mashoma anochajiswa zvidimbu zvinogona kufamba zvakasununguka, uye resistivity yavo yakakura.Kana insulator yakavhenekerwa nechiedza chine simba rakakura kudarika bhendi gap, maerekitironi ari mubhendi revalence anofara kune conduction bhendi, achisiya maburi mubhendi revalence, ese ari maviri anogona kuitisa magetsi, chiitiko chinozivikanwa se photoconductivity.Mazhinji insulators ane polarization properties, saka insulators dzimwe nguva anonzi dielectrics.Insulators ari insulating pasi penguva dzose voltages.Kana iyo voltage ichiwedzera kune imwe muganhu, dielectric breakdown ichaitika uye iyo insulating state ichaparadzwa.
Plastiki inogona kukamurwa kuita mapoka maviri: thermosetting uye thermoplastic.Iyo yekutanga haigone kuumbwazve kuti ishandiswe, uye iyo yekupedzisira inogona kugadzirwa zvakare.Thermoplasticity ine kureba kwakakura kwemuviri, kazhinji 50% kusvika 500%.Simba harisiyane zvachose mutsetse pakurebesa kwakasiyana.
Chinhu chikuru chepurasitiki ndeye resin.Resin inoreva musanganiswa wepolymer usina kusanganiswa nezvimwe zvakasiyana-siyana.Izwi resin rakatanga kunzi lipids yakavanzwa nemhuka nemiti, senge rosin uye shellac.
Plastics insulators, asi kune marudzi akawanda emapurasitiki.Izvo zvemagetsi zvemapurasitiki akasiyana zvakasiyana, uye simba re dielectric rakasiyanawo.
