Purasitiki yakasvibiswa inoreva rudzi rwepurasitiki iyo midziyo inogona kusangana nezvinodiwa zvekushandisa, kushanda kunoramba kusingachinji panguva yekuchengetedza, uye inogona kuderedzwa kuita zvinhu zvakatipoteredza pasi pemamiriro ekunze ezvakatipoteredza mushure mekushandiswa.Naizvozvo, inozivikanwawo sepurasitiki inoshatisa zvakatipoteredza.
Kune akasiyana mapurasitiki matsva: mapurasitiki anogona kuomeswa, biodegradable mapurasitiki, mufananidzo/oxidation/biodegradable mapurasitiki, carbon dioxide-based biodegradable plastics, thermoplastic starch resin mapurasitiki anoparara.
Polymer degradation inoreva maitiro ekutyora iyo macromolecular cheni yepolymerization inokonzerwa nemakemikari uye emuviri zvinhu.Iyo yekushatisa maitiro ayo mapolymer anooneswa kumamiriro ezvakatipoteredza akadai seokisijeni, mvura, mwaranzi, makemikari, zvinosvibisa, masimba emagetsi, zvipembenene nedzimwe mhuka, uye hutachiona hunodaidzwa kushatisa kwezvakatipoteredza.Kudzikisira kunoderedza huremu hwemamorekuru epolymer uye kunoderedza hunhu hwepolymer zvinhu kudzamara iyo polymer zvinhu yarasikirwa nekushandiswa kwayo, chiitiko chinozivikanwawo sekuparara kwekuchembera kwezvinhu zvepolymer.
Kuparara kwekuchembera kwemapolymer kwakanangana nekugadzikana kwemapolymers.Kusakara kwekuchembera kwemapolymer kunopfupisa hupenyu hwebasa hwemapurasitiki.
Kubva pakatanga mapurasitiki, masayendisiti ave akazvipira kurwisa kuchembera kwezvinhu zvakadaro, ndiko kuti, kudzidza kwekudzikamisa, kuitira kuti pave nepamusoro-kugadzikana zvinhu zvepolymer, uye masayendisiti munyika dzakasiyana-siyana ari kushandisawo hunhu hwekuchembera. mapolymers kugadzira mapurasitiki ekushatisa kwezvakatipoteredza.
Nzvimbo huru dzekushandisa dzemapurasitiki anoparara ndeaya: yekurima mulch firimu, akasiyana marudzi emabhegi ekurongedza epurasitiki, mabhegi emarara, mabhegi ekutenga munzvimbo dzekutenga uye midziyo yekudyira inoraswa.
Degradation Concept
Maitiro ekushatisa emapurasitiki anoshatisa nharaunda anonyanya kusanganisira biodegradation, photodegradation uye kushatisa kemikari, uye aya matatu makuru ekusvibisa maitiro ane synergistic, synergistic uye inobatana mhedzisiro pane mumwe nemumwe.Semuenzaniso, photodegradation uye oxide degradation inowanzoenderera panguva imwe chete uye inosimudzirana;Biodegradation inonyanya kuitika mushure meiyo photodegradation process.
Future Trend
Iko kudiwa kwepurasitiki inoparara kunotarisirwa kuwedzera nguva dzose, uye zvishoma nezvishoma kutsiva mazhinji echinyakare epurasitiki akagadzirwa zvigadzirwa.
Pane zvikonzero zviviri zvikuru zvinokonzeresa izvi, 1) Kuwedzera kuziva kweveruzhinji nezvekuchengetedzwa kwezvakatipoteredza kunokurudzira vanhu vazhinji kuti vagadzirise kuita eco-hushamwari chigadzirwa.2) Kuvandudza tekinoroji kudzikisa mutengo wekugadzira wezvigadzirwa zvepurasitiki zvinoodza.Nekudaro, kudhura kwakanyanya kwemareni anoparara uye kusimba kwekugara kwemusika wavo nemapurasitiki akasiyana atovepo zvinoita kuti zviome kuti mapurasitiki anoomeswa apinde mumusika.Naizvozvo, iyo biodegradable plastiki yaisazokwanisa kutsiva echinyakare epurasitiki mune pfupi tun.
