Ukuthuthukiswa kobuchwepheshe bepulasitiki kuyashintsha usuku ngalunye oludlulayo.Ukuthuthukiswa kwezinto ezintsha zezinhlelo zokusebenza ezintsha, ukuthuthukiswa kokusebenza kwemakethe yezinto ezibonakalayo, kanye nokuthuthukiswa kokusebenza kwezicelo ezikhethekile kungachazwa njengezinkomba ezimbalwa ezibalulekile zokuthuthukiswa kwezinto ezintsha kanye nokuqanjwa kabusha kwesicelo.Ngaphezu kwalokho, ukuvikelwa kwemvelo kanye nokuwohloka kuye kwaba yinto evelele yamapulasitiki amasha.
Yiziphi izinto ezintsha?
I-Bioplastics: I-Nippon Electric ine-bioplastics esanda kwakhiwa esekelwe ezitshalweni, ukusebenza kwazo okushisayo kuqhathaniswa nalokho kwensimbi engagqwali.Inkampani ixube imicu yekhabhoni enobude bamamilimitha ambalwa nobubanzi obungamamilimitha angu-0.01 kanye nokunamathiswa okukhethekile ku-polylactic acid resin eyenziwe ngommbila ukuze kukhiqizwe uhlobo olusha lwe-bioplastic ene-conductivity ephezulu eshisayo.Uma i-carbon fiber engu-10% ixubene, ukuqhutshwa kokushisa kwe-bioplastic kuqhathaniswa nalokho kwensimbi engagqwali;lapho kufakwa i-carbon fiber engu-30%, i-thermal conductivity ye-bioplastic iphindwe kabili kuneyensimbi engagqwali, futhi ukuminyana kuyi-1/5 kuphela yensimbi engagqwali.
Kodwa-ke, ucwaningo nokuthuthukiswa kwe-bioplastics kunqunyelwe emikhakheni yezinto zokusetshenziswa ezisekelwe ku-bio noma ama-bio-monomers noma ama-polymers akhiqizwa ukuvutshelwa kwe-microbial.Ngokukhula kwezimakethe ze-bio-ethanol kanye ne-bio-diesel eminyakeni yamuva nje, i-bio-ethanol ne-glycerol zisetshenziswa njengezinto zokusetshenziswa zokukhiqiza.Ubuchwepheshe be-bioplastics buye bathola ukunakwa okukhulu futhi buye bathengiswa.
Ifilimu yepulasitiki entsha eshintsha umbala: Inyuvesi yaseSouthampton e-United Kingdom kanye ne-Darmstadt Institute for Plastics eJalimane ngokubambisana bathuthukise ifilimu yepulasitiki eshintsha umbala.Ukuhlanganisa imiphumela yemvelo neyokwenziwa yokubona, ifilimu empeleni iyindlela entsha yokwenza izinto zishintshe umbala ngokunembile.Le filimu yepulasitiki eshintsha umbala iyifilimu ye-plastic opal, eyakhiwe ngezimbulunga zepulasitiki ezimbondelene endaweni enezinhlangothi ezintathu, futhi iqukethe ama-nanoparticles e-carbon amancane phakathi kwama-plastic sphere, ukuze ukukhanya kungabi kuphela phakathi kwama-plastic sphere izinto ezizungezile.ukubonakaliswa okuvela ezifundeni ezisemaphethelweni phakathi kwalezi zinhlayiya zepulasitiki, kodwa futhi kusukela phezulu kwe-carbon nanoparticles egcwala phakathi kwalezi zinhlayiya zepulasitiki.Lokhu kujulisa kakhulu umbala wefilimu.Ngokulawula umthamo wezinhlayiya zepulasitiki, kungenzeka ukukhiqiza izinto ezikhanyayo ezihlakaza kuphela ama-spectral frequencies athile.
Igazi elisha lepulasitiki lepulasitiki: Abacwaningi eNyuvesi yaseSheffield e-United Kingdom benze “igazi lepulasitiki” lokwenziwa elibukeka njengodaka oluwugqinsi.Uma nje incibilika emanzini, ingampontshelwa ezigulini, engasetshenziswa njengegazi ezinqubweni eziphuthumayo.ezinye izindlela.Lolu hlobo olusha lwegazi lokwenziwa lwenziwe ngamangqamuzana epulasitiki.Kunezigidi zama-molecule epulasitiki ocezwini lwegazi lokwenziwa.Lawa ma-molecule afana nosayizi nokuma kwawo kuma-molecule e-hemoglobin.Bangakwazi futhi ukuthwala ama-athomu ensimbi, ahambisa umoya-mpilo kuwo wonke umzimba njenge-hemoglobin.Njengoba izinto ezingavuthiwe ziyipulasitiki, igazi lokwenziwa lilula futhi kulula ukulithwala, alidingi ukuba lifakwe esiqandisini, linesikhathi eside sokusebenza, linokusebenza kahle okuphakeme kunegazi lokwenziwa langempela, futhi libiza kancane ukulenza.
Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, amapulasitiki amasha ayaqhubeka nokuvela.Izakhiwo zokuvikela ukushisa, ukumelana nokushisa nokumelana nomlilo kwamanye amapulasitiki aphezulu wobunjiniyela kanye nezinhlanganisela zibaluleke kakhulu.Ngaphezu kwalokho, ukuvikelwa kwemvelo kanye nokuwohloka kuye kwaba yinto evelele yamapulasitiki amasha.
