Ndedzipi dzazvino biodegradable tableware sarudzo? Chii chakasiyana? Inventory yezvakakurumbira zvinoraswa zvinoshatisa tableware pamusika
Mumamiriro ezvinhu ekusimudzira kuchengetedzwa kwezvakatipoteredza, mabhizinesi akawanda zvishoma nezvishoma ari kutsiva mabhokisi ezvokudya zvemasikati anoraswa nemidziyo yetafura inoparara kuderedza kusvibiswa kwezvakatipoteredza. Kune zvakare akawanda uye akawanda marudzi emabhokisi ane hushamwari uye anoshatisa emasikati arikuonekwa pamusika.
Saka chii chinonzi biodegradable lunch box? Ndezvipi zvikamu zvikuru zvebhokisi remasikati rinoparara? Ndeupi mutsauko uripo pakati pemabhokisi emasikati anoparara akagadzirwa nezvinhu zvakasiyana?
Biodegradable tableware inoreva tableware inogona kuita biochemical reactions pasi pechiito chemicroorganisms (mabhakitiriya, molds, algae) uye ma enzymes munzvimbo yechisikigo, zvichikonzera kuumbwa kwekunze kune shanduko yemukati yemhando, pakupedzisira kuumba kabhoni dhaibhorosi nemvura.
Kune marudzi maviri ezvigadzirwa zvinoshandiswa patafura inoparara: imwe inogadzirwa nezvinhu zvakasikwa, zvakadai sezvigadzirwa zvemapepa, mashanga, starch, nezvimwewo, izvo zvinogona kuderedzwa zvakakwana, inozivikanwawo sezvigadzirwa zvakatipoteredza; Imwe mhando inogadzirwa kubva mupurasitiki sechinhu chikuru, ichiwedzera zvinhu zvakaita se starch uye photosensitizers, izvo zvinogona kuderedzwa zvishoma.
Nhasi, ngatitarisei kune inoraswa yakasvibiswa tableware pamusika.
Corn starch based tableware
Corn starch based tableware yakajairika biodegradable chikafu bhokisi mumusika wazvino. Chinhu chikuru che starch ichibage, saka dzimwe nguva inonzi corn starch based. Nekudaro, iyi mhando yebhokisi rechikafu inonyatso musanganiswa westarch uye yechinyakare petroleum yakavakirwa PP plastiki, inonzi bio yakavakirwa kunze kwenyika.
Corn starch based tableware inokonzeresa humiro hwezvinhu zvese kudonha kuburikidza ne biodegradation ye starch, asi petroleum yakavakirwa PP mushure mekudonha haisati yaparara. Chiyero chekuora chinogona kusvika 40% -80% zvichienderana nekuumbwa kwebhokisi rekudya kwemasikati, saka inogona kungoonekwa sebhokisi rekudya kwemasikati rinoora, kwete rinopera zvachose.
Naizvozvo, chibage starch yakavakirwa patafuraware inogona kungotsiva zvishoma zvigadzirwa zvepurasitiki uye parizvino iri gakava rakasiyana kune epurasitiki tableware pamusika.
Pulp molded tableware (plant fiber molded tableware)
Panyaya yezvigadzirwa, mabhokisi akaumbwa anoraswa ekudya kwemasikati anoshandisa mafiibhi echirimwa semashanga egorosi uye nzimbe bagasse semidziyo, pasina kuwedzera chero zvinhu zvePP. Iwo anoumbwa kuburikidza nepulp molding wet pressing process, uye chikafu chegiredhi chekuwedzera senge chisina mvura uye neoiri chiratidzo chinowedzerwa kune pulp kuti uwane mhedzisiro yekubata chikafu chinotonhora uye chinopisa.
Dyara fiber inoshatisa masikati mabhokisi zvakare ndeimwe yeanonyanya kushanda marudzi emabhokisi emasikati mumusika wazvino. Kutora Hainan Province, iyo yaive yekutanga kurambidza epurasitiki tableware, semuenzaniso, Hainan Province yakarambidza zvachose kushandiswa, kutenderera, kutengesa, uye kuchengetwa kwepurasitiki tableware. Pulp yakaumbwa tableware pasina mubvunzo inova yakanakira purasitiki inotsiva.
Bagasse Sugarcane pulp anoraswa masikati mabhokisi ndeemhando yakaora zvachose, iyo inogona kuderedzwa zvachose kuita organic zvinhu mukati memazuva makumi mapfumbamwe pasi pemamiriro ekugadzira maindasitiri kana emumba, achidzokera kune zvakasikwa. Iwo chaiwo biodegradable zvinhu uye zvine zvimwe zvakanakira munzira yekurambidzwa kwepurasitiki.
PLA yakasvibiswa tableware
PLA mabhokisi ekudya kwemasikati anoshatisa anowanzo anoreva zvigadzirwa zvinosanganisa PLA akaumbwa mafirimu ane pulp akaumbwa zvigadzirwa mu pulp molding process, zvinoti PLA coated products.
PLA composite firimu inogadzirwa uye inogadziriswa kubva ku polylactic acid seyakabikwa, inogona kupiswa uye kusanganiswa pa pulp molding uye mapepa ezvigadzirwa. Iyo ifirimu inoodza zvachose.
Polylactic asidhi (PLA) rudzi rutsva rwezvinhu zvinoora zvinogadzirwa kubva kune starch inotorwa kubva kune inovandudzwa chirimwa zviwanikwa. Starch mbishi dzinowanikwa kuburikidza nesaccharification kuti iwane glucose, iyo inozoviriswa nemamwe madhiri kuburitsa yakakwira-kuchena lactic acid. Zvadaro, imwe molecular weight polylactic acid inogadzirwa kuburikidza nemakemikari synthesis nzira.
Nekubatanidza iyo lamination process ne pulp yakaumbwa zvigadzirwa, kushandiswa kwemvura uye mafuta ekudzingira ejenti anogona kuchengetedzwa, ayo anogona kuvhara pores e pulp akaumbwa zvigadzirwa. Mukushandiswa chaiko, tableware inoderedza kufema kwechigadzirwa, zvichikonzera kushanda kwepamusoro kwekudzivirira uye nguva yakareba yekuisa.
