Kuenzaniswa nezvimwe zvinhu, mapurasitiki ane zvinotevera zvishanu maitiro ekuita:
Huremu huremu: Purasitiki chinhu chakareruka chine hukama density kugovera pakati pe0.90 ne2.2.Naizvozvo, kunyangwe mapurasitiki anogona kuyangarara pamusoro pemvura, kunyanya purasitiki ine furo, nekuda kweiyo micropores mairi, magadzirirwo acho akareruka, uye hukama hwehukama hunongova 0.01.Ichi chivakwa chinobvumira mapurasitiki kuti ashandiswe mukugadzira zvigadzirwa zvinoda kuderedzwa uremu.
Yakanakisa kugadzikana kwemakemikari: Mapurasitiki mazhinji ane yakanaka corrosion kuramba kumakemikari akadai seasidhi uye alkalis.Kunyanya iyo polytetrafluoroethylene (F4) inowanzozivikanwa semambo wepurasitiki, kugadzikana kwayo kwemakemikari kwakatonaka kupfuura iyo yegoridhe, uye haizoparari kana yakabikwa mu "aqua regia" kwemaawa anopfuura gumi.Nekuti F4 ine yakanakisa kugadzikana kwekemikari, chinhu chakanakira kusaita ngura, senge F4 inogona kushandiswa sechinhu kuendesa marara uye viscous fluid pombi.
Yakanakisa magetsi ekudzivirira kushanda: Mapurasitiki akajairwa haaite maconductor emagetsi, uye kupikisa kwavo kwepamusoro uye vhoriyamu kuramba yakakura kwazvo, iyo inogona kuratidzwa munhamba kusvika 109-1018 ohms.Iyo yekuputsa voltage yakakura, uye iyo dielectric kurasikirwa tangent kukosha idiki.Naizvozvo, mapurasitiki ane huwandu hwakasiyana hwekushandisa mumagetsi uye maindasitiri emuchina.
Vasina kunaka kupisa conductor vane mhedzisiro yekudzikisa ruzha uye kubatwa nekuvhunduka: Kazhinji kutaura, kupisa kwemafuta epurasitiki kwakadzikira, zvakaenzana ne1/75-1/225 yesimbi., zviri nani kuvharira inzwi uye kushomeka kuramba.Panyaya yekupisa kwekupisa, mahwindo epurasitiki egirazi rimwe chete akakwira 40% kupfuura magirazi ealuminium mahwindo ega, uye mahwindo egirazi maviri akakwira 50%.Mushure mokunge hwindo repurasitiki rasanganiswa negirazi rinodzivirira, rinogona kushandiswa mudzimba, zvivako zvehofisi, mawadhi uye mahotera, kuchengetedza kupisa munguva yechando uye kuchengetedza mari yemhepo yemhepo muzhizha, uye zvikomborero zviri pachena.
Kupararira kwakakura kwesimba remagetsi uye simba rakananga rakakwirira: mamwe mapurasitiki akaoma sematombo nesimbi, uye mamwe akapfava semapepa nematehwe;kubva pamaonero ezvivakwa zvemakanika senge kuoma, kusimba kwesimba, kurebesa uye kusimba kwesimba remapurasitiki, iyo yekugovera renji Wide, kune yakawanda nzvimbo yesarudzo.Nekuda kweiyo diki chaiyo giravhiti uye yakakwirira simba repurasitiki, ine yakakwirira chaiyo simba.Zvichienzaniswa nezvimwe zvinhu, mapurasitiki anewo zvikanganiso zviri pachena, zvakadai sokuva nyore kupisa, kwete sepamusoro mukuoma sesimbi, kusava nehanya nekukwegura, uye kwete kupisa-kupisa.
