Ke likhetho life tse fumanehang hona joale tsa "biodegradable tableware"? Phapano ke efe? Lenane la lintho tse tsebahalang tse lahlehang tse senyehang 'marakeng
Boemong ba ho khothaletsa ts'ireletso ea tikoloho, likhoebo tse ntseng li eketseha butle-butle li ntse li nkela mabokose a tloaelehileng a lijo tsa motšeare sebaka ka lijana tse senyehang ho fokotsa tšilafalo ea tikoloho. Ho boetse ho na le mefuta e mengata ea mabokose a lijo tsa motšeare a senyehileng a hlahang 'marakeng.
Joale lebokose la lijo tsa motšeare le ka senyehang ke eng? Likarolo tse kholo tsa lebokose la lijo tsa motšeare tse senyehang ke life? Phapano ke efe lipakeng tsa mabokose a lijo tsa motšeare a senyehang a entsoeng ka thepa e fapaneng?
Biodegradable tableware e bua ka li-tableware tse ka kenang tšebetsong ea lik'hemik'hale tlas'a ts'ebetso ea likokoana-hloko (libaktheria, hlobo, algae) le li-enzyme tse tikolohong ea tlhaho, tse bakang hlobo e kantle ho liphetoho tsa boleng ba kahare, 'me qetellong ea theha carbon dioxide le metsi.
Ho na le mefuta e 'meli ea lisebelisoa tse sebelisoang bakeng sa lisebelisoa tsa tafole tse senyehang: e' ngoe e entsoe ka thepa ea tlhaho, e kang lihlahisoa tsa pampiri, lehlaka, starch, joalo-joalo, tse ka senyehang ka ho feletseng, tse tsejoang hape e le lihlahisoa tsa tikoloho; Mofuta o mong o entsoe ka polasetiki e le karolo ea mantlha, ho eketsa lintho tse kang starch le photosensitizers, tse ka senyehang hanyane.
Kajeno, ha re shebeng lisebelisoa tsa tafole tse senyehang 'marakeng.
Lijo tse nang le starch ea poone
Corn starch based tableware ke lebokose le tloaelehileng la lijo tse senyehang 'marakeng oa hajoale. Mohloli o ka sehloohong oa starch ke poone, kahoo ka linako tse ling e bitsoa corn starch based. Leha ho le joalo, mofuta ona oa lebokose la lijo ha e le hantle ke motsoako oa starch le polasetiki ea setso e thehiloeng ho peterole ea PP, e bitsoang bio e thehiloeng kantle ho naha.
Lisebelisoa tsa tableware tse thehiloeng ho starch ea poone li etsa hore thepa eohle ea 'mele e oele ka lebaka la ho senyeha ha starch, empa PP e thehiloeng ho petroleum ka mor'a ho putlama e ntse e sa senyeha. Sekhahla sa ho senyeha se ka fihla ho 40% -80% ho latela sebopeho sa lebokose la lijo tsa motšehare, kahoo e ka nkoa feela e le lebokose la lijo tsa motšehare le senyehang, eseng le senyehang ka ho feletseng.
Ka hona, li-tableware tse thehiloeng ho starch ea poone li ka nkela lihlahisoa tsa polasetiki sebaka ka mokhoa o sa fellang 'me hajoale ke phehisano e fapaneng le lisebelisoa tsa polasetiki' marakeng.
Disebediswa tsa tafola tse bopehileng ka pulp (faeba ya semela e bopehileng ka tafole)
Mabapi le lisebelisoa tse tala, mabokose a lijo tsa mots'eare a bōpiloeng a sebelisa likhoele tsa semela joalo ka joang ba koro le mekotla ea 'moba joalo ka lisebelisoa tse tala, ntle le ho eketsa lisebelisoa tsa PP. Li thehoa ka mokhoa oa ho hatella metsi ka pulp, 'me li-additives tsa boemo ba lijo tse kang bopaki ba metsi le oli li eketsoa ho pulp ho finyella phello ea ho tšoara lijo tse batang le tse chesang.
Mabokose a lijo tsa motšeare a ka senyehang a limela ke e 'ngoe ea mefuta e sebetsang ka ho fetesisa ea mabokose a lijo tsa motšeare 'marakeng oa hajoale. Ho nka Profinse ea Hainan, eo e neng e le eona ea pele ea ho thibela lijana tsa polasetiki, e le mohlala, Profinse ea Hainan e thibetse ka ho feletseng tšebeliso, ho potoloha, ho rekisa le ho boloka lijana tsa polasetiki. Pulp molded tableware ntle le pelaelo e fetoha sebaka se loketseng sa polasetiki.
Mabokose a lijo tsa motšea a lahloang a Bagasse 'moba ke a mofuta o senyehang ka ho feletseng, o ka senyehang ka ho feletseng hore e be lintho tse phelang nakong ea matsatsi a 90 tlas'a maemo a manyolo a indasteri kapa a malapeng, a khutlela tlhahong. Ka sebele ke lisebelisoa tse senyehang 'me li na le melemo e itseng tseleng ea thibelo ea polasetiki.
PLA tableware e senyehang
Mabokose a senyehileng a lijo tsa mots'eare a PLA hangata a bua ka lihlahisoa tse kopanyang lifilimi tse kopaneng tsa PLA le lihlahisoa tse bopehileng ka har'a mokhoa oa ho bopa, e leng lihlahisoa tse koahetsoeng ka PLA.
Filimi e kopantsoeng ea PLA e hlahisoa le ho sebetsoa ho tloha ho polylactic acid e le lisebelisoa tse tala, tse ka futhumatsang le ho kopanngoa holim'a pulp molding le lihlahisoa tsa pampiri. Ke filimi e senyehang ka ho feletseng.
Polylactic acid (PLA) ke mofuta o mocha oa lintho tse senyehang habonolo tse entsoeng ka starch e nkiloeng mehloling ea limela e nchafalitsoeng. Lisebelisoa tse tala tsa starch li fumanoa ka saccharification ho fumana tsoekere, e ntan'o lomosoa ka mefuta e itseng ho hlahisa lactic acid e phahameng. Joale, e itseng molecular boima polylactic acid e synthesized ka lik'hemik'hale synthesis mekhoa.
Ka ho kopanya ts'ebetso ea lamination le lihlahisoa tse entsoeng ka pulp, tšebeliso ea lisebelisoa tse thibelang metsi le oli e ka bolokeha, e ka tiisang li-pores tsa lihlahisoa tse entsoeng ka makhasi. Ts'ebelisong ea 'nete, tableware e fokotsa phefumoloho ea sehlahisoa, e bakang ts'ebetso e phahameng ea ho kenya letsoho le nako e telele ea ho koala.
