Kodi pulasitiki ndi kondakita kapena insulator?

Kodi pulasitiki ndi kondakita kapena insulator?Choyamba, tiyeni timvetsetse kusiyana pakati pa ziwirizi: Kondakitala ndi chinthu chomwe chimakhala ndi mphamvu yaing'ono yolimbana ndi mphamvu komanso kuyendetsa magetsi mosavuta.Insulator ndi chinthu chomwe sichiyendetsa magetsi nthawi zonse.Makhalidwe a insulators ndiakuti milandu yabwino ndi yoyipa m'mamolekyu imamangidwa mwamphamvu, ndipo pali tinthu tating'onoting'ono tomwe timayimitsidwa tomwe timatha kuyenda momasuka, ndipo resistivity yawo ndi yayikulu.Pamene insulator imayatsidwa ndi kuwala ndi mphamvu yaikulu kuposa kusiyana kwa bandi, ma elekitironi mu gulu la valence amasangalala ndi gulu la conduction, kusiya mabowo mu gulu la valence, lomwe lingathe kuyendetsa magetsi, chinthu chodziwika kuti photoconductivity.Ma insulators ambiri ali ndi polarization properties, choncho zotetezera nthawi zina zimatchedwa dielectrics.Ma insulators ndi insulating pansi ma voltages wamba.Mphamvu yamagetsi ikakwera mpaka malire ena, kuwonongeka kwa dielectric kudzachitika ndipo malo otchingira adzawonongedwa.

Pulasitiki akhoza kugawidwa m'magulu awiri: thermosetting ndi thermoplastic.Zakale sizingapangidwenso kuti zigwiritsidwe ntchito, ndipo zotsirizirazi zikhoza kupangidwanso.Thermoplasticity imakhala ndi kutalika kwakukulu kwa thupi, nthawi zambiri 50% mpaka 500%.Mphamvu sizimasiyana motsatira mzere pamatali osiyanasiyana.
Chigawo chachikulu cha pulasitiki ndi utomoni.Utoto umatanthauza gulu la polima lomwe silinasakanizidwe ndi zowonjezera zosiyanasiyana.Mawu akuti resin poyambirira adatchulidwa kuti lipids opangidwa ndi nyama ndi zomera, monga rosin ndi shellac.
Pulasitiki ndi zotetezera, koma pali mitundu yambiri ya mapulasitiki.Mphamvu zamagetsi za mapulasitiki osiyanasiyana ndizosiyana, ndipo mphamvu ya dielectric imakhalanso yosiyana.
