Zeziphi iinketho zangoku ze-biodegradable tableware?Yintoni umahluko?Uluhlu lwezinto ezithandwayo zetafile ezilahlayo ezilahlayo kwimarike

Kumxholo wokukhuthaza ukukhuselwa kwendalo, amashishini amaninzi ngokuthe ngcembe atshintsha iibhokisi eziqhelekileyo zesidlo sasemini ezilahlwayo kunye neetafile ezonakalayo ukunciphisa ukungcoliseka kwendalo.Kukwakho ngakumbi nangakumbi iintlobo zeebhokisi zesidlo sasemini ezilungele ukusingqongileyo nezingonakaliswayo ezivela emarikeni.

Ke yintoni i-biodegradable lunch box?Ngawaphi amacandelo aphambili ebhokisi yesidlo sasemini eyonakalayo?Uthini umahluko phakathi kweebhokisi zesidlo sasemini ezonakeleyo ezenziwe ngezinto ezahlukeneyo?

I-tableware ye-Biodegradable tableware ibhekisela kwi-tableware enokuthi ingene kwi-biochemical reactions phantsi kwesenzo se-microorganisms (ibhaktheriya, i-molds, i-algae) kunye ne-enzymes kwindawo yendalo, ebangela ukungunda kwangaphandle kutshintsho lwangaphakathi, ekugqibeleni yenze i-carbon dioxide kunye namanzi.

Kukho iintlobo ezimbini zezixhobo ezisetyenziselwa i-tableware eyonakalisayo: enye yenziwe ngezinto zendalo, ezifana neemveliso zephepha, i-straw, isitashi, njl., ezinokuthi zithotywe ngokupheleleyo, ezaziwa ngokuba yimveliso ehambelana nokusingqongileyo;Olunye uhlobo lwenziwe ngeplastiki njengeyona nto iphambili, yongeza izinto ezifana nesitashi kunye ne-photosensitizers, ezinokuthi zonakaliswe ngokuyinxenye.

Namhlanje, makhe sijonge kwizinto ezilahlwayo zetafile ezingonakalayo kwimarike.

Isitatshi esisekwe kwitafile yesitatshi

I-Corn starch esekwe kwi-tableware yibhokisi yokutya eqhelekileyo enokubola kwimarike yangoku.Owona mthombo wesitashi ngumbona, ngoko ngamanye amaxesha kuthiwa yi corn starch.Nangona kunjalo, olu hlobo lwebhokisi yokutya eneneni ngumxube wesitashi kunye neplastiki ye-petroleum esekwe kwi-PP, ebizwa ngokuba yi-bio esekwe phesheya.

I-tableware yesitatshi esekwe kwi-Corn ibangela ukuba iipropathi ezibonakalayo zemathiriyeli iyonke ziwohloke ngokudilizwa kwe-biodegradation yestatshi, kodwa i-petroleum esekwe kwi-PP emva kokuwa ayikaboli.Izinga lokuthotywa lingafikelela kwi-40% -80% ngokusekelwe ekubunjweni kwebhokisi lesidlo sasemini, ngoko ke inokuthathwa njengebhokisi lesidlo sasemini esonakeleyo, kungekhona esonakala ngokupheleleyo.

Ke ngoko, isitashi sombona esekwe kwitafile zinokuthatha indawo yeemveliso zeplastiki ngokuyinxenye kwaye ngoku yeyona ndlela iphikisanayo kwitafile yeplastiki kwimarike.

Iitafile ezibunjiweyo zentlama

Ngokwemathiriyeli ekrwada, iibhokisi zesidlo sasemini ezibunjiweyo ezibunjiweyo zisebenzisa imicu yezityalo enjengeendiza zengqolowa kunye nengxowa yommoba njengemathiriyeli ekrwada, ngaphandle kokongeza nayiphi na imathiriyeli yePP.Zenziwa ngokusebenzisa i-pulp yokubumba inkqubo yokucinezela okumanzi, kunye nezongezo zebakala lokutya ezifana nokungangeni kwamanzi kunye nobungqina beoyile zongezwa kwi-pulp ukufezekisa umphumo wokubamba ukutya okubandayo kunye nokutshisa.

Iibhokisi zesidlo sasemini ezingonakali zezityalo zezinye zezona ntlobo zisebenzayo zeebhokisi zesidlo sasemini kwimarike yangoku.Ukuthatha iPhondo laseHainan, elalilelokuqala ukuvala iitafile zeplastiki, njengomzekelo, iPhondo laseHainan likuthintele ngokupheleleyo ukusetyenziswa, ukujikeleziswa, ukuthengiswa, kunye nokugcinwa kweetafile zeplastiki.Iitafile ezibunjiweyo zePulp ngokungathandabuzekiyo ziba yeyona nto ilungileyo endaweni yeplastiki.

I-Bagasse Iibhokisi zesidlo sasemini ezilahlwayo ze-Sugarcane zezohlobo olunokonakala ngokupheleleyo, olunokuthi luthotywe ngokupheleleyo lube yinto ephilayo kwisithuba seentsuku ezingama-90 phantsi kweemeko zomgquba wemizi-mveliso okanye wekhaya, ubuyela kwindalo.Zizinto eziphathekayo ezinokonakala ngokwenene kwaye zineenzuzo ezithile kwindlela yokwalelwa kweplastiki.

Itafile ye-PLA eyonakalisayo

Iibhokisi zesidlo sasemini ezonakeleyo ze-PLA zihlala zibhekisa kwiimveliso ezidibanisa iifilimu ezidibeneyo ze-PLA kunye neemveliso ezibunjiweyo ze-pulp kwinkqubo yokubumba i-pulp, ezizezi iimveliso ezigqunywe yi-PLA.

Ifilimu edibeneyo ye-PLA iveliswa kwaye iqhutywe kwi-polylactic acid njengento ekrwada, enokufudunyezwa kwaye idibaniswe kwi-pulp yokubumba kunye nemveliso yephepha.Yifilimu enokubola ngokupheleleyo.

I-Polylactic acid (i-PLA) luhlobo olutsha lwezinto ezinokubola ezenziwe nge-biodegradable ezenziwe kwi-starch ephuma kwimithombo yezityalo ezivuselelekayo.Izinto zesitatshi ezikrwada zifumaneka nge-saccharification ukuze kufunyanwe i-glucose, ethi emva koko ivundiswe ngeentlobo ezithile ukuvelisa i-asidi ye-lactic ephezulu.Emva koko, i-molecular weight polylactic acid idityaniswe ngeendlela ze-chemical synthesis.

Ngokudibanisa inkqubo ye-lamination kunye neemveliso ezibunjiweyo ze-pulp, ukusetyenziswa kwamanzi kunye ne-oyile yokugxotha i-oyile kunokugcinwa, okunokutywina iipores zeemveliso ezibunjiweyo ze-pulp.Ekusetyenzisweni okwenyani, i-tableware inciphisa ukuphefumla kwemveliso, okukhokelela ekusebenzeni okuphezulu kokugquma kunye nexesha elide lokugquma.
