Nekukurumidza kusimudzira kweindasitiri yekurongedza, kuvandudzwa kwehunyanzvi hwekushandisa tekinoroji uye kuwedzera kutarisisa kwepfungwa yekuchengetedzwa kwezvakatipoteredza, kuwedzera kwepurasitiki kurongedza kunogadzirwa nezvinhu zvine hushamwari kwezvakatipoteredza. emabhegi epurasitiki ezvakatipoteredza: mapurasitiki akadzokororwa, mapurasitiki anoparara uye epurasitiki inodyiwa.
Recycled Plastic
Plastiki yakadzokororwa ndiko kushandiswazve kwepurasitiki, kuburikidza nemishini yekukuya blade, kuitira kupedzisa kushandiswazve kwepurasitiki.
Purasitiki yakadzokororwa inoreva zvinhu zvepurasitiki zvakasvibirira zvakawanikwa zvakare mushure mekugadzirisa marara epurasitiki nenzira dzemuviri kana dzemakemikari senge pretreatment, kunyungudutsa granulation uye gadziriso, iko kushandiswazve kwepurasitiki.
Mabhenefiti makuru epurasitiki akadzokororwa akachipa kupfuura mutengo mutsva wezvinhu, kunyangwe zviri pakuita kwese uye zvivakwa hazvina kunaka sechinhu chitsva chakasimba, asi isu hatidi kushandisa mune zvakawanda zvigadzirwa zvakagadzirwa zvivakwa uye. kuita kwezvose zvakanaka zvinhu kuti zvigadzire, saka izvo zvakaparadza zvakawanda zvisingakoshi hunhu, uye iyo yakagadziridzwa zvinhu zvakasiyana, zvinoenderana nezvinodiwa zvakasiyana, Inongoda chete kugadzirisa chimwe chikamu chehunhu, inogona kugadzira chinoenderana chigadzirwa. , kuitira kuti pasave nekurasikirwa kwezvinhu.
Purasitiki inoparara
Mapurasitiki akaparara anoreva mapurasitiki ari nyore kusvibiswa munzvimbo yakasikwa nekuda kwekuwedzera kwezvimwe zvinowedzera (zvakadai se starch, modified starch kana imwe cellulose, photosensitizer, biodegradation agent, nezvimwewo) mukugadzira.Mapurasitiki anoparara anowira muzvikamu zvina zvikuru:
1.Biodegradable Plastic
Dry, haifaniri kudzivisa chiedza, zvakasiyana-siyana zvekushandisa, kwete chete inogona kushandiswa pakurima epurasitiki firimu, mabhegi ekuputira, uye anoshandiswa zvakanyanya mumunda wemishonga.Nekuvandudzwa kwechizvino-zvino biotechnology, mapurasitiki anoora akabhadharwa zvakanyanya uye akave nzvimbo nyowani inopisa mukutsvagisa nekusimudzira.
2.Photodegradable Plastiki
A photosensitizer inowedzerwa kupurasitiki kuti iparadze zvishoma nezvishoma pasi pezuva.Icho chiri chechizvarwa chekare chepurasitiki yakasvibiswa, uye kukanganisa kwayo ndeyokuti nguva yekuparara haisati yasvika nekuda kwezuva uye kuchinja kwemamiriro ekunze, saka hazvibviri kudzora nguva yekuora.
3.Water Degradation yePlastiki
Wedzera mvura inonwisa zvinhu mupurasitiki, mushure mekushandisa, kurasa mumvura inogona kunyunguduka, inonyanya kushandiswa mumishonga uye midziyo yehutano (yakadai semagirovhosi ekurapa), nyore kuparadza uye kurapa disinfection.
4. Chiedza / biodegradable Plastiki
Photodegradation uye microbial musanganiswa wekirasi yepurasitiki, ine zvese chiedza uye microbial kushatisa kwepurasitiki maitiro.
Inodyiwa Plastic
Purasitiki inodyika imhando yekurongedza inodyiwa, kureva, inodyiwa yekurongedza, kazhinji inoumbwa nesitachi, mapuroteni, polysaccharide, mafuta, musanganiswa zvinhu, zvinoshandiswa zvakanyanya senge plastiki kuputira, kurongedza firimu, kurongedza kwepamusoro, kurongedza chikafu, keke kurongedza, seasoning package, nezvimwewo.
Nekuvandudzwa kweindasitiri yechikafu yemazuva ano, kurongedza chikafu kunogara kuchivandudzwa.Rudzi rutsva rwechikafu kurongedza tekinoroji zvinhu, zvinodyiwa kurongedza, izvo zvinogona kuvandudza kupokana pakati pekurongedza zvinhu uye kuchengetedza kwezvakatipoteredza, inomira pachena.Edible packaging material inoreva chinhu chakakosha chekurongedza chinogona kushandurwa kuita chinodyiwa chemhuka kana vanhu mushure mekunge basa rekurongedza raitwa.Edible packaging material imhando yekurongedza pasina tsvina, imhando yezvishandiso-yakavakirwa kuchengetedzwa kwemamiriro ekunze ekurongedza zvinhu.
