Zvigadzirwa zvepurasitiki, sezvinhu zvakakosha muindasitiri yemazuva ano uye hupenyu hwezuva nezuva, zvinoshandiswa zvakanyanya mumhando dzakasiyana siyana nekuda kwekusiyana kwavo kwakanakira kuita. Kuita kwavo kunonyanya kuratidzwa mune yavo yemuviri, kemikari, uye kugadzirisa zvivakwa, izvo pamwe chete zvinotarisa chiyero uye kukosha kwemapurasitiki.
Panyama, mapurasitiki anoratidzirwa nehuremu huremu uye simba rakakwirira. Nepo kuwanda kwemapurasitiki akawanda kuchingova chimwe-chikamu chimwe chete{2}}chisere kune chimwe chesimbi, nzira dzekugadzirisa (zvakadai sefiber reinforcement kana mineral fillers) dzinogona kunatsiridza magadzirirwo awo, zvichikonzera mutoro wakanaka-kubereka nekupfeka{4}}kuramba kushanda. Uyezve, mapurasitiki anopa zvakanakisa insulation zvivakwa, zvichivaita zvinhu zvakakosha zvemagetsi nemagetsi zvigadzirwa. Semuenzaniso, polyethylene (PE) uye polypropylene (PP) inoshandiswa zvakanyanya mukuvharwa kwewaya uye tambo nekuda kweakanakisa dielectric maitiro.
Panyaya yemakemikari zvivakwa, mapurasitiki anowanzo shingirira mukuora uye kuchembera. Kusiyana nesimbi, iyo inotapukirwa neacid uye alkali corrosion, mapurasitiki akagadzikana munzvimbo dzakaoma dzemakemikari uye nekudaro anowanzoshandiswa mumidziyo yakaita semapaipi emakemikari uye matangi ekuchengetera. Nekudaro, mamwe mapurasitiki, akadai sepolystyrene, anotapukirwa nekudzikira pasi penguva refu yeultraviolet mwenje, izvo zvinoda kuwedzerwa kwema stabilizer kuti avandudze kusamira kwemamiriro ekunze. Processability ndiyo imwe mukana mukuru wemapurasitiki. Plastics inogona kuumbwa kuburikidza neakasiyana maitiro, anosanganisira jekiseni kuumba, extrusion, uye kuvhuvhuta kuvhuvhuta, kuchinjika kune yakaoma madhizaini madhizaini ane hunyanzvi hwepamusoro uye mutengo wakaderera. Semuenzaniso, thermoplastics inogona kudzokororwa kupisa kuti ipfave, zvichiita kuti zvive nyore kudzokorodza uye kuenderana neinoenderera mberi zvinodiwa.
Pasinei nekushanda kwakanaka kwezvigadzirwa zvepurasitiki, hushamwari hwavo hwezvakatipoteredza hunoramba huri nharo yekukakavara. Mafambisirwo eramangwana mubio{{1}patsvagiridzo yezvinyorwa uye budiriro uye matekinoroji ekudzokorodza anovimbisa kuenderera mberi nekuderedza kukanganiswa kwePlastiki kwezvakatipoteredza uku achichengetedza kushanda kwawo kwepamusoro. Pakazere, kuita kwezvigadzirwa zvepurasitiki zvinoita kuti zvive chinhu chakakosha chinotsigira kusimudzira nzanga yanhasi.
