Common plastiki zvinhu:
Ipurasitiki inowanzoshandiswa haisi chikamu chimwe chete, inogadzirwa kubva kune zvakawanda zvinhu.Pakati pavo, high molecular polymers (kana synthetic resins) ndiyo inonyanya kuumba mapurasitiki.Uye zvakare, kuti uvandudze mashandiro emapurasitiki, zvinhu zvakasiyana-siyana zvekubatsira, senge mafirita, mapurasitiki, mafuta ekuzora, uye zvigadzikiso, zvinofanirwa kuwedzerwa kune akakwira mamorekuru makomisheni., Colorants, antistatic agents, nezvimwewo, zvinogona kuva mapurasitiki nekushanda kwakanaka.
Plastic additives, inozivikanwawo seplastic additives, makomisheni anofanirwa kuwedzerwa kuti avandudze mashandiro epolymer (synthetic resin) kana kuvandudza mashandiro eresin pachayo kana polima (synthetic resin) yagadziriswa.Semuenzaniso, kuitira kuderedza kupisa kwekuumbwa kwepolyvinyl chloride resin, plasticizer inowedzerwa kuita kuti chigadzirwa chive chinyoro;mumwe muenzaniso wekuwedzera furo rinoputira gadziriro yerakareruka, risingaite vibration, rinodzivirira kupisa, uye ruzha-inodzivirira furo;Iyo tembiricha yekuora iri padhuze nekushisa kwekugadzira, uye kuumba hakugone kuwanikwa pasina kuwedzera kupisa stabilizer.Naizvozvo, mapurasitiki ekuwedzera anotora chinzvimbo chakakosha mukuumbwa kwepurasitiki.
Plastics mapolymer compounds (macromolecules), anowanzozivikanwa semapurasitiki kana resin, ayo anogadzirwa nemamonomers sezvishandiso kuburikidza nekuwedzera polymerization kana polycondensation maitiro.Kuumbwa uye chimiro zvinogona kuchinjwa zvakasununguka.Inoumbwa nesynthetic resins uye fillers.Plasticizer, stabilizer, lubricant, pigment uye zvimwe zvinowedzera.
