Sainzi neTekinoroji Daily News (Mutori wenhau Wu Changfeng) Tsvina yepurasitiki yakakonzera kukuvadza kukuru kunharaunda yezvakatipoteredza uye kutyisidzira kukuru kuhutano hwevanhu.Kuvandudzwa kwechizvarwa chitsva chezvakagadzikana zvepurasitiki zvimwe zvinhu zvave pedyo.Mutori wenhau akadzidza kubva kuYunivhesiti yeSainzi neTekinoroji yekuChina kuti chikwata chemudzidzi wechikoro cheYu Shuhong chakabudirira kugadzira bhaisikopo rakasimba kwazvo, rakaomarara, uye rakajeka rinoita segoko rakaita semusanganiswa, uye rakabudirira kuvaka “chidhina- fiber” shell-like layered structure, Firimu rinoratidza zvinhu zvemuchina zvinodarika zvemapurasitiki echinyakare, uye rinoratidza zvinhu zvakatanhamara kupfuura mafirimu epurasitiki.Mhedzisiro yetsvagiridzo yakaburitswa ichangoburwa pa "Materials".
Sekureva kwemishumo, iyi firimu repamusoro-pachena uye yakakwirira-haze firimu rinobatsira kubva kune dense shell-senge "brick-fiber" chimiro.Mapores ari mukati memufirimu anozadzwa kuti ave nechokwadi chekufambisa mwenje, uye iyo optical haze inosimbiswa neiyo interface yekuparadzira nanosheets uye cellulose.Saka, zvinokwanisika kuwana kujeka kwepamusoro kweanopfuura 73% uye yakakwirira optical haze inopfuura 80% muinooneka spectrum wavelength range ye370-780 nanometers.Panguva imwecheteyo, iyo firimu inewo yakanakisa zvimiro zvekusimba kwepamusoro uye kusimba kwepamusoro, ayo ari 6 nguva uye 3 nguva kupfuura ekutengesa PET epurasitiki mafirimu.Pamusoro pezvo, matatu-dimensional network ye nanofibers uye "brick-fiber" shell-yakafanana dhizaini dhizaini inogona kuvharisa kupararira kwekutsemuka.Panguva imwecheteyo, iyo fiber kuonda mhedzisiro inogona kuwedzera iyo hydrogen bond density pakati pemafiber mune izvo zvinhu uye kukurudzira fiber kutsvedza panguva yekutambanudza firimu.Ita kuti zvinhu zvive nesimba rose uye kuoma kwepamusoro.Uyezve, iyo firimu inogona kuramba yakagadzikana chimiro uye kuita pa250 ° C, uye ine basa riri nani kuita kupfuura mafirimu epurasitiki munzvimbo dzakanyanyisa.
Vatsvagiri vakati iyi biomimetic firimu zvinhu inobatanidza yakanakisa optical, mechanika uye yekupisa zvivakwa, uye inogona kuve yakazara.biodegradablepasi pemamiriro echisikigo, kukunda dambudziko rekuti marara epurasitiki anonetsa kudzikisira, uye kusangana nezvinodiwa zvekujeka kwemaziso, Nepo kuchinjika, mutengo wakaderera, uye kugadzikana kwedimensional pakupisa kwepamusoro uye kwakaderera kunodiwa, kutenderera kwehupenyu hwese kwakasvibira uye kusvibiswa-pasina kusvibiswa. , uye ichange iine tarisiro yakafara yekushandiswa mumunda wemagetsi anochinjika mune ramangwana.
Kubudirira kwetsvagiridzo iyi inhau huru kune inochinjika indasitiri yekurongedza.Senyanzvi inogadzira yekurongedza inochinjika, OEMY Environmental Hushamwari Packaging Kambani ichashandisa zvizere akasiyana emhando yepamusoro biodegradable mafirimu semidziyo yemabhegi ekurongedza.Ipai vatengi nekugadzirwa kwepamusoro-mhando zvizeredegradable packaging bags, kuita kuti nyika ive shoma zvigadzirwa zvepurasitiki uye kuderedza kusvibiswa kwezvakatipoteredza.
Chinja purasitiki yako yekurongedza kuita biodegradable uye compostable packaging, ndapota taura neOEMY Environmental Friendly Packaging.Email:admin@oemypackagingbag.com
