N“Kule mihla, ndingena kwiivenkile zekofu,Iistraw ezibolayo ze-PLA"ayiseyonto intsha. Abantu abaninzi banamathandabuzo anjalo xa bedibana neemveliso ezinjalo:Kutheni iistraw ze-PLA ezibhalwe “ezibolayo” zingaboli ixesha elide xa ziphoswe kwindawo yendalo?Ixabiso layo lokusingqongileyo lihlala phi kanye kanye? Enyanisweni, iimpawu zokusingqongileyo ze-PLA aziyonto “yobuqili”, kodwa kufuneka zisekelwe kwingqiqo yesayensi kunye nokusetyenziswa ngokuchanekileyo. Namhlanje, ngokwembono yoshishino, siza kuxoxa ngokufutshane ngexabiso eliphambili, imida yokusetyenziswa kunye neendawo eziphambili zokuwohloka kweestraw ze-PLA..

ICANDELO I

Yintoni iPLA? I-Alchemy yanamhlanje evela kwiNdalo

PI-LA, isishunqulelo se-polylactic acid, sisixhobo esibolayo esisekelwe kwibhayoloji. Izinto zaso eziluhlaza zivela kwizityalo zesitatshi ezifana nombona kunye ne-cassava, eziguqulwa zibe zizinto ze-polymer ezinamandla aphezulu ngokubilisa, ukucoca kunye ne-polymerization, zenze umjikelo wokuqala ovaliweyo "ovela kwindalo". Ngokungafaniyo neeplastiki zemveli ezixhomekeke kwi-petroleum, uphawu lwayo oluhlaziyekayo lolona ncedo luphambili.

Ngokwedatha evela kwi-China Plastics Processing Industry Association, ukuvelisa itoni e-1 ye-PLA kunokunciphisa iitoni ezi-2.1 zokusetyenziswa kwepetroleum kunye neetoni ezi-3.2 zokukhutshwa kwekhabhoni. Esi siphumo sokunciphisa ikhabhoni siqatshelwa ziimarike zehlabathi, kwaye sikwasisizathu esiphambili sokuba iinkampani eziphambili zeti yobisi zasekhaya ziyithathe njengenye indlela eyintloko endaweni yeentshulube zeplastiki.

Isithembiso: Inkqubela yokwenyani yePLA Straws Offer

FOkokuqala, banika amava angcono.Abaninzi bayakhumbula iingxaki ngee-straw zephepha—ziba buthathaka kwaye zibe mdaka emva kwemizuzu engamashumi amabini kwisiselo. Ii-straw ze-PLA zisombulula oku kakhulu. Ziqinile, azinancasa, kwaye zivakala zifana neplastiki yendabuko, oko kuthetha ukuba "zinobuhlobo nokusingqongileyo" akusafuneki zivakale ngathi ziyavumelana.

Okwesibini, banesiphelo esicacileyo sesayensi.Ngaphantsi komgangatho ofanelekileyoukwenza umgquba kwimizi-mvelisokwiimeko ezithile, indlela yokuwohloka kwe-PLA ichazwe kakuhle. Izixhobo ezikhethekileyo zibonelela ngobushushu obuhlala ixesha elide (55-70°C), ukufuma okuchanekileyo, kunye neentsholongwane ezithile. Apha,Iistraw zePLAidla ngokuqhekeka ibe yi-carbon dioxide, amanzi, kunye ne-biomass kwiintsuku ezingama-90 ukuya kwezili-180, igqibezela umjikelo ukusuka kwisityalo ukuya emhlabeni.

Okubaluleke kakhulu, batshintsha umthombo.Ukuvelisa itoni enye ye-PLA kunokonga malunga neetoni ezimbini zepetroliyam kwaye kunciphise ukukhutshwa kwekhabhoni ngaphezulu kweetoni ezintathu. Imele ujikelezo: ukusuka ekumbeni iindawo zokugcina iifosili zakudala ukuya ekusebenziseni izixhobo zezityalo ezihlaziyekayo minyaka le.

ICANDELO LESITHATHU

Imida Yokusetyenziswa: Ayingonakalisi Umhlaba Wonke, Ifuna Uhlengahlengiso Lwendawo

Ingxaki ikwimeko "ezifanelekileyo" kanye.

Uninzi lokungaqondani malunga ne-PLA luvela ekulinganiseni "okubolayo" "nokubola kuyo nayiphi na indawo". Oko kuthiwa "kungalunganga" ngokwenene yimida yesiganeko:

Ngokuphathelele ubushushu, ubushushu bokutshintsha kweglasi ye-PLA bumalunga nama-50℃, buthamba kwaye buguquguquka lula xa budlula obu bushushu, bufanele kuphela iziselo ezibandayo. Iinguqulelo ezimelana nobushushu obuphezulu zifuna izinto zokuguqula, nto leyo enciphisa ukusebenza kakuhle kokuguguleka nge-10%-30%. Ngokuphathelele imeko-bume, ukuguguleka kwayo kuxhomekeke kwizityalo ezithile kwi-compost yemizi-mveliso, kunye nomjikelo wokuguguleka kweminyaka engaphezu kwama-50 kumhlaba obushushu obuqhelekileyo, kwaye zimbalwa izixeko zasekhaya ezineendawo ezinkulu zokunyanga. Ngokuphathelele ixabiso, ixabiso langoku leyunithi yeestraw ze-PLA yi-0.08-0.1 yuan, amaxesha ama-3-5 kuneeplastiki zemveli, kwaye ixabiso kulindeleke ukuba lehle ngaphezulu kwama-30% emva kokwandiswa komthamo ngo-2026.

INXALENYE IV

Imbono Elungeleleneyo: Yintoni i-PLA Straws kunye ne-non-in-in

PIistraw ze-LA zimele ubuchwepheshe obuxabisekileyo bokutshintsha, kodwa aziyonto intle. Zisisitshixo esisebenza kuphela ukuba sihambelana nesitshixo—inkqubo yokucubungula inkunkuma ehambelanayo. Kubathengi: Ziphathe njengomjelo wenkunkuma okhethekileyo. Khangela isiqinisekiso esithembekileyo esinokugqunywa (njenge-BPI) kwaye ulandele isikhokelo sendawo sokulahla inkunkuma yokutya okanye kwiibhini eziluhlaza eziya kwiindawo zorhwebo.

KwiShishini: Bagxininisa ukuba ukuveliswa kwezinto ezintsha zodwa akwanelanga. Izisombululo ezipheleleyo zifuna utshintsho olucwangcisiweyo: uyilo olungcono lwemveliso, imfundo yabathengi, kwaye, okubaluleke kakhulu, utyalo-mali kwiziseko zophuhliso lwe-compost.

Inyathelo Elibalulekileyo Ekuguqulweni Kwendalo Esingqongileyo

PI-LA ayisosisombululo esifanelekileyo sokusingqongileyo, kodwa iphula ingqiqo yokuba "ukhuseleko lokusingqongileyo kufuneka luncame amava" kwaye ibonelela ngendlela efanelekileyo yokutshintshwa kweplastiki. Ngokusetyenziswa kwe-PLA straws, ishishini lokutya lasekhaya linciphisa inkunkuma yeplastiki ngaphezulu kweetoni ezili-120,000 ngonyaka, liqokelela amava okutshintshwa kwezinye iindidi. Ngokuphuculwa kwetekhnoloji kunye nezixhobo, i-PLA iya kuqhubeka nokunika amandla utshintsho lokusingqongileyo, isebenza njengebhulorho ebalulekileyo phakathi kwezinto eziluhlaza zangoku nezexesha elizayo.
