Ngaba ilaphu elingaphothiweyo liyabola

Yintoni ilaphu elingalukwanga?

Ilaphu elingalukwanga luhlobo olutsha lwemathiriyeli ehambelana nokusingqongileyo. Ngokungafaniyo namalaphu esintu afuna iinkqubo ezintsonkothileyo ezinje ngokusonta kunye nokuluka, sisixhobo sothungelwano lwefiber esenziwe ngokuxuba iintsinga okanye izigcwalisi ngeglu okanye iintsinga ezinyibilikisiweyo ezikwimo enyibilikisiweyo zisebenzisa inwebu, i-mesh, okanye iindlela zokuziva. Amalaphu angalukwanga anamandla aphezulu, ukuphefumla okuhle, ukuxhathisa ukunxiba, ukuguquguquka okuhle, ukungenwa kwamanzi kunye neempawu zobungqina bokufuma, kwaye ke ngoko zisetyenziswe ngokubanzi kubomi bemihla ngemihla.

Ithini imeko yokuthotywa kwelaphu elingalukwanga?

Ilaphu elingalukwanga lahlukile kwiiplastiki ezinokubola ngenxa yokuba yenziwe ngeentsinga zokwenziwa, iintsinga zeplanga, iintsinga ezihlaziyiweyo, kunye nezinye izinto, kwaye azinakonakaliswa okanye ziboliswe ziintsholongwane. Nakwimeko yendalo, amalaphu angalukwanga athatha amashumi eminyaka, kwaneenkulungwane, ukubola. Ukuba inani elikhulu lelaphu elingalukwanga lilahlwa kwindawo engqongileyo ixesha elide, liya kubangela ingozi enkulu kwindalo.

Nangona kunjalo, kukwakho nemathiriyeli yelaphu elingalukwanga elinokubolekwa ngebhayoloji elikhoyo ngoku, kwaye nokuba ilaphu elingalukwanga liyakwazi ukubola kuxhomekeke kukwakheka kwalo. Amalaphu angalukwanga enziwe nge-polylactic acid (PLA) kunye nezinye izinto eziguquguqukayo ze-biodegradable ziyakwazi ukubola, ngelixa amalaphu angalukwanga enziwe kwizinto zeplastiki zemveli ezifana ne-polypropylene (PP) kunye ne-polyethylene (PE) ayinakuchithwa.

Inkcazo kunye noncedo lwamalaphu angalukwanga anokubola

Ilaphu elingalukwanga le-Biodegradable libhekiselele kwilaphu elingalukwanga elinokuthi liboliswe ngama-microorganisms, izilwanyana kunye nezityalo, i-hydrolysis okanye i-photolysis phantsi kweemeko ezithile. Xa kuthelekiswa nelaphu leplastiki lemveli elingalukwanga, linokunciphisa ngokufanelekileyo ungcoliseko lokusingqongileyo.
Kuluntu lwanamhlanje, ukukhuselwa kwendalo kube yinkxalabo yehlabathi jikelele, kwaye amalaphu angalukwanga angaboliyo athandwa kakhulu ngenxa yeempawu zawo zokusingqongileyo.

Iindidi kunye neempawu zamalaphu angalukwanga anokubola

Amalaphu angalukwanga adla ngokusetyenziswa ngokufuthi aquka ezi ndidi zintathu zilandelayo:

Ilaphu elingalukwanga elisekwe kwisitatshi elinokonakala

Isitashi esekwe biodegradable ilaphu non-elukiweyo yi ilaphu non-elukiweyo friendly ngokusingqongileyo ikakhulu iqulunqwe istatshi kwaye yenziwe ngokongeza plasticizers, arhente zokuqinisa, izinto zokuqinisa, njl. Xa kuthelekiswa amalaphu zemveli zeplastiki non-elukiweyo, amalaphu istatshi esekelwe biodegradable non-elukiweyo zineempawu ezibalaseleyo antioxidant kunye biodegradability elungileyo. Ukongeza, ilaphu elingalukwanga elisekwe kwistatshi elinokonakala linexabiso eliphantsi kwaye lilaphu elingalukwanga elinobuhlobo nokusingqongileyo elineendleko eziphezulu.

I-Polylactic acid esekwe kwilaphu elingalukwanga elinokonakala

Ilaphu le-Polylactic acid elisekwe kwi-biodegradable non-loven lilaphu elingalukwanga elinobuhlobo ngokusingqongileyo elenziwe ikakhulu nge-polylactic acid ngeendlela zemichiza yepolima. Xa kuthelekiswa namalaphu eplastiki emveli angalukwanga, amalaphu e-polylactic asekwe kwi-biodegradable angalukwanga anokubola okulungileyo kunye nokuzinza kweekhemikhali. Ukongeza, ilaphu le-polylactic acid esekwe biodegradable non-elukiweyo inokuthoba ngokufanelekileyo i-CO2 kunye namanzi, ikhuphe isixa esikhulu samandla obushushu, iyenze ibe yinto efanelekileyo yokusingqongileyo engalukwanga ilaphu.

I-cellulose esekwe kwilaphu elingalukwanga elinokonakala

Ilaphu elingalukwanga elenziwe nge-cellulose elisekwe kwi-biodegradable lilaphu elingalukwanga elinobuhlobo nokusingqongileyo elenziwe ikakhulu ngeselulosi kwaye lenziwe ngokongeza ii-agent zokuqinisa kunye nemathiriyeli. Xa kuthelekiswa namalaphu eplastiki emveli angalukwanga, amalaphu e-cellulose asekwe kwi-biodegradable angalukwanga anokubola okulungileyo kunye neempawu ezibonakalayo. Ukongeza, ilaphu le-cellulose esekwe kwi-biodegradable engalukwanga ikwanako ukuphefumla okulungileyo kunye nokufunxa ukufuma, nto leyo eyenza ukuba ibe lilaphu elingalukwanga elinobuhlobo ngokusingqongileyo.

Ukuqukumbela

Ilaphu elingalukwanga ngokwalo liwohloka kancinane, kodwa kukwakho nemathiriyeli yelaphu elingalukwanga elibolisekayo elikhoyo ngoku. Kwizinto zelaphu ezingalukwanga ezingenako ukuthotywa ngokukhawuleza, iindlela ezikhuselekileyo kunye nezokusingqongileyo kufuneka zamkelwe ukunciphisa impembelelo yazo kwindalo. Kwimathiriyeli yelaphu engalukiweyo enokubola, kufuneka kwandiswe ukukhuthazwa kunye nokutyhala. Yenza abantu abaninzi baqonde impembelelo yamalaphu angalukwanga, ngokudibeneyo ukukhusela okusingqongileyo, kunye nokufezekisa uphuhliso oluzinzileyo.
