Kuvandudzwa kwehunyanzvi hwepurasitiki kuri kuchinja zuva rega rega.Kugadziridzwa kwezvinhu zvitsva zvekushandisa kutsva, kuvandudzwa kwekuita kwemusika wezvinhu uripo, uye kuvandudzwa kwekuita kweakakosha maapplication anogona kutsanangurwa seakati wandei akakosha madhairekitori ekuvandudzwa kwezvinhu uye hunyanzvi hwekushandisa.Mukuwedzera, kuchengetedzwa kwezvakatipoteredza uye kuora kwave kwave kuratidzwa kwemapurasitiki matsva.
Ndezvipi zvinhu zvitsva?
Bioplastics: Nippon Electric ichangobva kugadzirwa bioplastics yakavakirwa pamiti, iyo inopisa conductivity inofananidzwa neyesimbi isina tsvina.Iyo kambani yakasanganisa kabhoni fibers nehurefu hwemamirimita akati wandei uye dhayamita 0.01 millimita uye yakakosha inonamira mu polylactic asidhi resin yakagadzirwa nechibage kuti ibudise rudzi rutsva rwebioplastic ine high thermal conductivity.Kana 10% kabhoni fiber yakasanganiswa mukati, iyo inopisa conductivity yebioplastic inofananidzwa neyesimbi isina tsvina;apo 30% kabhoni fiber yakawedzerwa, iyo inopisa conductivity yebioplastic yakapetwa kaviri yesimbi isina tsvina, uye density inongova 1/5 yeiyo yesimbi isina tsvina.
Nekudaro, kutsvagisa nekusimudzira kwebioplastics kunogumira kuminda yebio-based raw materials kana bio-monomers kana mapolymer anogadzirwa nemicrobial fermentation.Nekuwedzera kwemisika yebio-ethanol uye bio-dhiziri mumakore achangopfuura, bio-ethanol uye glycerol zvinoshandiswa seyakagadzirwa zvigadzirwa.Iyo tekinoroji yebioplastics yakagamuchira kutariswa kwakawanda uye yakatengeswa.
Firimu idzva repurasitiki rinoshandura ruvara rwepurasitiki: Yunivhesiti yeSouthampton muUnited Kingdom neDarmstadt Institute for Plastics muGermany vakabatana vakagadzira firimu repurasitiki rinoshandura ruvara.Kubatanidza echisikigo uye artificial optical mhedzisiro, iyo firimu ichokwadi nzira nyowani yekuita kuti zvinhu zvinyatso shandura ruvara.Iyi firimu repurasitiki rinoshandura ruvara ipurasitiki opal firimu, iro rinoumbwa nemapuranga epurasitiki akaturikidzana munzvimbo ine mativi matatu, uye zvakare ine diki kabhoni nanoparticles pakati pemapuranga epurasitiki, kuitira kuti chiedza chisangove pakati pemapuranga epurasitiki uye. zvinhu zvakapoteredza.fungidziro kubva kumatunhu ekumucheto pakati peaya epurasitiki spheres, asiwo kubva pamusoro pekabhoni nanoparticles inozadza pakati peaya mapuranga epurasitiki.Izvi zvinonyanya kudzika ruvara rwefirimu.Nekudzora huwandu hwemapuranga epurasitiki, zvinokwanisika kugadzira zvinhu zvakareruka zvinoparadzira chete mamwe ma spectral frequencies.
Ropa idzva repurasitiki repurasitiki: Vatsvakurudzi vepaYunivhesiti yeSheffield kuUnited Kingdom vakagadzira "ropa repurasitiki" rekugadzira rinoratidzika semucheka wakakora.Chero bedzi iyo yakanyungudutswa mumvura, inogona kuwedzerwa kune varwere, iyo inogona kushandiswa seropa mune zvekukurumidzira maitiro.dzimwe nzira.Rudzi rutsva urwu rweropa rekugadzira rakagadzirwa nemamorekuru epurasitiki.Kune mamiriyoni emamorekuru epurasitiki muchidimbu cheropa rakagadzirwa.Aya mamorekuru akafanana muhukuru uye chimiro nemamorekuru ehemoglobin.Vanogona zvakare kutakura maatomu esimbi, ayo anotakura okisijeni mumuviri wese senge hemoglobin.Sezvo raw material ipurasitiki, ropa rekugadzira rakareruka uye riri nyore kutakura, haridi kuiswa mufiriji, rine nguva refu yechokwadi, rine hunyanzvi hwekushanda kupfuura ropa chairo rekugadzira, uye haridhure kugadzira.
Nekukurumidza kukura kwesainzi uye tekinoroji, mapurasitiki matsva anoramba achionekwa.Iyo insulating zvivakwa, kupisa kupisa uye kushorwa kwemoto kweimwe yepamusoro-yekupedzisira engineering mapurasitiki nemakomponi zvakanyanya kukosha.Mukuwedzera, kuchengetedzwa kwezvakatipoteredza uye kuora kwave kwave kuratidzwa kwemapurasitiki matsva.
