Degradable packaging bhegi, chirevo chacho chinoshatisa, asi chiputiriso chinodzikira chakakamurwa kuita "chinoshatisa" uye "chinoshatisa zvizere" marudzi maviri.
Iyo biodegradable yepurasitiki bhegi yakagadzirwa nehuswa hwezvirimwa uye humwe hushamwari kumuviri wemunhu uye nharaunda, dzakasiyana nemapurasitiki matatu ekugadzira, mushure memarara, pasi pekuita kweiyo biological nharaunda, inogona kuparara pachayo, zvisinei nevanhu kana nharaunda. hazvikuvadzi, ndezvepakeji yakasvibirira.Degradable plastic bag imhando yehomwe yekutenga inoraswa inogona kuderedzwa uye nyore nyore.
Mabhegi epurasitiki anoparara anogona kukamurwa kuita marudzi maviri kubva pamusiyano wezvigadzirwa uye nekuora zvinhu:
• Bhegi repurasitiki rinonyanya kugadzirwa nepurasitiki yepolyethylene, yakasanganiswa nestarch nezvimwe zvinosvibisa zvipenyu, zvinozivikanwawo sepurasitiki rinoodza.Rudzi urwu rwepurasitiki bhegi rinoora zvakanyanya nekuita kwema microorganisms.
• Imwe mhando inonyanya kugadzirwa ne polyethylene plastiki, yakasanganiswa nemineral powder yakadai se light desorption agent uye calcium carbonate, iyo inonziwo light desorption plastic bag.Rudzi urwu rwepurasitiki bhegi rinoputsika pasi pekuita kwezuva.
Saga rinoparara zvachose zvinoreva kuti masaga ese epurasitiki anoderedzwa kuita mvura necarbon dioxide.Nzvimbo huru yeiyi inoparara zvachose inogadziriswa kubva kuchibage, mufarinya uye zvimwe zvinhu kuita lactic acid, inozivikanwawo sePLA.Poly Lactic Acid (PLA) imhando nyowani yebiological substrate uye inogona kuvandudzwa biodegradable zvinhu.Starch raw material inocheneswa kuti iwane shuga, uye ipapo shuga uye mamwe madhiri anoviriswa kuti abudise kuchena kwelactic acid, uyezve iyo PLA ine humwe huremu hwemamorekuru inogadzirwa nemakemikari synthesis nzira.Iine biodegradability yakanaka.Mushure mekushandiswa, inogona kuderedzwa zvachose nehutachiona muzvisikwa pasi pemamiriro ezvinhu chaiwo, uye pakupedzisira inogadzira carbon dioxide nemvura.Iyo haisvibise nharaunda, iyo inobatsira zvikuru kuchengetedza zvakatipoteredza uye inzvimbo inoshamwaridzana nevashandi.
