Chii chinonzi biodegradable lunch box?
Biodegradable lunch box ibhokisi rekudya kwemasikati rinogona kuderedzwa nehutachiona (bhakitiriya, mold, algae) munzvimbo yechisikigo pasi pekuita kwema enzymes, biochemical reactions, zvichikonzera shanduko mukuonekwa kwe mold kune yemukati mhando, uye pakupedzisira kuumbwa kwe. carbon dioxide nemvura.Iyo yese degradation process inogona kuoreswa kuita zvinhu zvisingakuvadzi pasina kugadzirwa kwekuita, inova nzira refu kwazvo.Biodegradable lunch boxes akapedza marara kuwedzera kuGB18006.3-2020 "general technical zvinodiwa zvekuraswa biodegradable catering midziyo" kushatisa kuita, kunofanirwa kuve nekudzokorodza kukosha, nyore kushandisa zvakare, kana nyore kurasirwa ivhu uye yakanyanya-tembiricha yekuisa manyowa.
Chechipiri, ndezvipi zvikamu zvikuru zvemabhokisi ekudya kwemasikati anodeka?
Biodegradable lunch boxes inogadzirwa nemhando mbiri dzezvinhu: imwe inogadzirwa nezvinhu zvechisikigo, senge zvigadzirwa zvemapepa, mashanga, starch, nezvimwewo, izvo zvinogona kuderedzwa, zvinonziwo zvakatipoteredza zvigadzirwa;imwe yacho yakagadzirwa nepurasitiki sechinhu chikuru, kuwedzera starch, photosensitizers nezvimwe zvinhu.
1, Biodegradable zvakasikwa zvinhu masikati bhokisi
Mabhokisi ekudya emasikati anoraswa akagadzirwa nezvinhu zvechisikigo anozivikanwawo semabhokisi ekudya kwemasikati anodedera.Biodegradable lunch box ndeye yakanyanyisa kuchengetedzwa kwezvakatipoteredza chigadzirwa.Yakagadzirwa nesitachi seyakanyanya mbishi zvinhu, ichiwedzera yegore yekukura nguva yekudyara faibha poda uye akakosha ekuwedzera, uye inogadziriswa nemakemikari uye emuviri nzira kugadzira biodegradable inokurumidza kudya mabhokisi.Sezvo starch iri biodegradable natural polymer, inoora kuita glucose uye pakupedzisira mvura uye carbon dioxide pasi pekuita kwe microorganisms.Mukuwedzera, iyo iyo iyo yakabatanidzwa nayo inosanganiswa ihwowo hwakakwana husina kunaka, saka zvinogona kutaurwa kuti hazvina kukanganisa kune zvakatipoteredza.Nzvimbo huru yesitachi, iyo mbishi yekugadzira, inogona kuve yegore yekukura nguva zvirimwa zvakaita sechibage, mbatatisi, mbambaira uye mufarinya.Sezvineiwo, biodegradable lunch mabhokisi haana kukwana, semuenzaniso, mazhinji ekugadzirwa kwezvinhu zvirimwa zvekudya, uye kune matambudziko akadai sekudzivirira mold achiri kuda kugadziriswa.
2, Biodegradable epurasitiki masikati bhokisi
Kugadzira zvigadzirwa zvemabhokisi ekudya kwemasikati akadaro anoraswa epurasitiki, iyo inonzi biodegradable plastiki ndeyekuwedzera imwe huwandu hwekuwedzera, senge photosensitizers, starch uye zvimwe zvigadzirwa mukugadzirwa kwepurasitiki.Nenzira iyi, biodegradable plastiki zvigadzirwa zvinogona kuomeswa kuita zvidimbu kubva muchimiro chazvo chakazara mushure mekushandiswa uye kuraswa muzvisikwa kwemwedzi mitatu yekuratidzwa, nekudaro kuvandudza nharaunda, zvishoma nekuona.Nekudaro, chikuru chinokanganisa tekinoroji iyi ndechekuti zvidimbu izvi hazvigone kuramba zvichidzikisira, asi zvinongotendeuka kubva muzvidimbu zvidiki kuita zvidimbu zvidiki zvepurasitiki, izvo zvisingakwanisi kuita basa rekubvisa kusvibiswa chena.
