Parizvino zvinhu zvinonyanya kufarirwa zvinoparara ndizvoPLAuye PBAT, ose ari maviri anogona kuparara zvachose.
Mapurasitiki anopararatarisa kukirasi yemapurasitiki ayo zvigadzirwa zvinogona kusangana nezvinodiwa zvekushandisa maererano nekuita, zvinoramba zvisina kuchinjwa panguva yekuchengetedza, uye zvinogona kuderedzwa kuita zvinhu zvisingakuvadzi zvakatipoteredza pasi pemamiriro ekunze ezvakatipoteredza mushure mekushandiswa.Nokudaro, inonziwo plastiki inoparadza zvakatipoteredza.
Kune akasiyana-siyana emhando nyowani dzemapurasitiki: mapurasitiki anoomeswa, biodegradable mapurasitiki,light/oxidation/biologically degradable plastics, carbon dioxide-based biodegradable plastics, uye thermoplastic starch resin mapurasitiki anoparara.
Polymer degradation inoreva maitiro ekupwanya polymerized macromolecular cheni nekuda kwemakemikari uye emuviri zvinhu.Iyo degradation process ye macromolecular chain breakage yemapolymers akaoneswa okisijeni, mvura, mwaranzi, makemikari, zvinosvibisa, magetsi masimba, zvipembenene uye dzimwe mhuka uye microorganisms kunonzi kushatisa kwezvakatipoteredza.
Kudzikisira kunoderedza huremu hwepolymer, uye hunhu hwepolymer zvinhu zvinodzikira kudzamara iyo polymer zvinhu yarasikirwa nekushandiswa kwayo.Ichi chiitiko chinonziwo kuchembera kushatisa kwepolymer zvinhu.
Kuparara kwekuchembera kwemapolymer kwakanangana nekugadzikana kwemapolymers.Kusakara kwekuchembera kwemapolymer kunopfupisa hupenyu hwebasa hwemapurasitiki.Nechikonzero ichi, kubvira pakatanga mapurasitiki, masayendisiti akazvipira kutsvagurudzo yekurwisa kuchembera kwezvinhu zvakadaro, ndiko kuti, kudzikamisa, kuitira kuti pave nekugadzikana kwepolymer zvinhu, uye masayendisiti kubva kunyika dzakasiyana-siyana ari kushandisawo. kuchembera kushatisa maitiro emapolymers.Mujaho wekugadzira mapurasitiki anoshatisa nharaunda.
Iwo makuru ekushandisa minda yemapurasitiki anoparara ndeaya: yekurima mulch film, akasiyana pmabhegi ekurongedza ekupedzisira,mabhegi emarara, mabhegi ekutenga mumashopu uye anoraswa tableware, nezvimwe.
