Yiziphi izinketho zamanje ze-tableware ze-biodegradable? Uyini umehluko? Uhlu lwezitsha zokudlala ezilahlwayo ezilahlwayo ezithandwayo emakethe

Esimeni sokugqugquzela ukuvikelwa kwemvelo, amabhizinisi anda kancane kancane ashintsha amabhokisi esidlo sasemini alahlwayo afake izitsha zetafula ezonakele ukuze kuncishiswe ukungcoliswa kwemvelo. Kukhona futhi nezinhlobo eziningi kakhulu zamabhokisi esidlo sasemini angenabungani futhi awonakaliswayo avela emakethe.

Ngakho-ke liyini ibhokisi lesidlo sasemini elingaboli? Yiziphi izingxenye eziyinhloko zebhokisi lesidlo sasemini esonakele? Uyini umehluko phakathi kwamabhokisi esidlo sasemini awohlokayo enziwe ngezinto ezahlukene?

I-tableware ye-biodegradable ibhekisela ku-tableware engabhekana nokusabela kwamakhemikhali e-biochemical ngaphansi kwesenzo samagciwane (amabhaktheriya, isikhunta, ulwelwe) kanye nama-enzyme endaweni yemvelo, okubangela ukukhunta kwangaphandle ekushintsheni kwekhwalithi yangaphakathi, ekugcineni kwakheke i-carbon dioxide namanzi.

Kunezinhlobo ezimbili zezinto ezisetshenziselwa i-tableware eyonakele: enye yenziwe ngezinto zemvelo, njengemikhiqizo yephepha, utshani, isitashi, njll., engase yonakaliswe ngokuphelele, eyaziwa nangokuthi imikhiqizo ehambisana nemvelo; Olunye uhlobo lwenziwe ngepulasitiki njengengxenye eyinhloko, lwengeza izinto ezifana nesitashi nama-photosensitizers, angonakaliswa kancane.

Namuhla, ake sibheke i-tableware engalahleka emakethe.

I-tableware ye-corn starch esekelwe

I-tableware ye-Corn starch iyibhokisi lokudla elivamile elibolayo emakethe yamanje. Umthombo oyinhloko wesitashi ummbila, ngakho ngezinye izikhathi ubizwa ngokuthi i-corn starch based. Kodwa-ke, lolu hlobo lwebhokisi lokudla empeleni luyingxube yesitashi kanye nepulasitiki ye-PP ye-petroleum yendabuko, ebizwa ngokuthi i-bio esekelwe phesheya.

I-tableware esekwe isitashi sombila idala ukuthi izici ezibonakalayo zayo yonke impahla ziwe ngokuwohloka kwe-biodegradation yesitashi, kodwa i-PP esekelwe ku-petroleum ngemva kokuwa ayikaboli. Izinga lokuwohloka lingafinyelela ku-40% -80% ngokusekelwe ekwakhiweni kwebhokisi lesidlo sasemini, ngakho-ke lingabhekwa njengebhokisi lesidlo sasemini elonakele, hhayi elonakele ngokuphelele.

Ngakho-ke, i-tableware esekwe isitashi sombila ingangena esikhundleni semikhiqizo yepulasitiki kancane futhi njengamanje iyindlela ephikisanayo ye-plastic tableware emakethe.

I-Pulp molded tableware (i-plant fiber molded tableware)

Ngokuphathelene nezinto zokusetshenziswa, amabhokisi esidlo sasemini abunjwe u-pulp asebenzisa imicu yezitshalo efana notshani lukakolweni kanye nesaka likamoba njengezinto zokusetshenziswa, ngaphandle kokungeza noma yiziphi izinto ze-PP. Zakhiwa ngenqubo yokucindezela emanzi yokubumba i-pulp, futhi izithasiselo zebanga lokudla ezifana nobufakazi obungangeni manzi kanye nowoyela zengezwa ku-pulp ukuze kuzuzwe umphumela wokubamba ukudla okubandayo nokushisayo.

Amabhokisi esidlo sasemini awonakaliswa yifayibha yezitshalo nawo angenye yezinhlobo ezisebenza kakhulu zamabhokisi esidlo sasemini emakethe yamanje. Sithatha iSifundazwe sase-Hainan, ebesingesokuqala ukuvimbela izitsha zepulasitiki, njengesibonelo, iSifundazwe sase-Hainan sikuvimbele ngokuphelele ukusetshenziswa, ukujikeleza, ukuthengiswa, nokugcinwa kwezitsha zepulasitiki. I-Pulp molded tableware ngokungangabazeki iba into efanelekile esikhundleni sepulasitiki.

I-Bagasse I-pulp yomoba amabhokisi esidlo sasemini alahlwayo ayingxenye yohlobo oluwohlokayo ngokuphelele, olungacekelwa phansi lube yizinto eziphilayo zingakapheli izinsuku ezingama-90 ngaphansi kwezimo zokuvundisa zezimboni noma zasendlini, zibuyela emvelweni. Ziyizinto ezibolayo ngempela futhi zinezinzuzo ezithile emgwaqeni wokuvinjelwa kwepulasitiki.

I-PLA tableware eyonakele

Amabhokisi esidlo sasemini e-PLA awonakele ngokuvamile abhekisela emikhiqizweni ehlanganisa amafilimu ayinhlanganisela ye-PLA nemikhiqizo ebunjiwe ye-pulp enqubweni yokubumba i-pulp, okuyimikhiqizo ehlanganiswe ne-PLA.

Ifilimu eyinhlanganisela ye-PLA ikhiqizwa futhi icutshungulwe kusuka ku-polylactic acid njengempahla eluhlaza, engashiswa futhi ihlanganiswe ekubunjweni kwe-pulp kanye nemikhiqizo yephepha. Ifilimu engaboli ngokuphelele.

I-Polylactic acid (PLA) iwuhlobo olusha lwezinto ezibolayo ezibolayo ezenziwe ngesitashi ezitholakala ezinsizeni zezitshalo ezivuselelekayo. Izinto ezisetshenziswayo zesitashi zitholakala nge-saccharification ukuze kutholwe i-glucose, esuke ivutshelwa ngezinhlobo ezithile ukuze kukhiqizwe i-lactic acid ene-high-purity. Khona-ke, isisindo esithile samangqamuzana e-polylactic acid sihlanganiswa ngezindlela zamakhemikhali.

Ngokuhlanganisa inqubo ye-lamination nemikhiqizo ebunjiwe ye-pulp, ukusetshenziswa kwama-ejenti angenawo amanzi kanye nowoyela kungasindiswa, okungavala ama-pores emikhiqizo ebunjiwe ye-pulp. Ekusetshenzisweni kwangempela, i-tableware inciphisa ukuphefumula komkhiqizo, okuholela ekusebenzeni okuphezulu kokufakelwa kanye nesikhathi eside sokufakwa.
