Kushandiswa kwehuni hwakajeka mukuvaka uye magetsi maitiro

Huni chinhu chakasimba uye chinogoneka chekuvaka, asi sechinhu chero chipi zvacho, chine zvipingamupinyi zvayo (inoora nekufamba kwenguva, inoora kubva kubhugi uye inovhara kupfuura kwechiedza).

Magirazi egirazi akajairika haasi nani zvakanyanya. Vanoita nyore kufuratira chiedza uye vanobvumira simba guru kuti riyerere mukati kana kunze kwechivako. Mainjiniya vakawana akanakisa pane ese ari maviri: danda rakajeka.

Masayendisiti Liangbing Hu, Dr. Mingwei Zhu nevamwe vavo kubva kuYunivhesiti yeMaryland vakakwanisa kuita bhuroka yehuni yakajeka, nokudaro vachiwana zvinhu zvinogona kushandiswa pakuvaka uye mumagadzirirwo emagetsi anobva pachiedza.

Masayendisiti akabvisa kubva mumatanda mamorekuru anoita kuti ive yakaoma uye yakasviba muruvara, uye akawana isina ruvara maseru zvimiro zve cellulose izere ne epoxy resin, nekudaro kugadzira huni hunonyanya kujeka.

“Izvi zvinogona kushandiswa mumotokari nekuti huni dzacho dziri pachena uye dzakasimba zvikuru,” akadaro Dr. Zhu, munyori wekutanga wekudzidza. "Unogonawo kuishandisa sechinhu chakasarudzika chekuvakisa."

Nekubvisa pendi nemakemikari, huni yakave yakajeka, asi zvakare yakasimba uye insulator iri nani kupfuura girazi, uye ine pfuma ye biodegradability zviri nani kupfuura plastiki.

Nzira yaiita kuti huni huve pachena yakatanga nekuibika mumvura yakasanganiswa nesodium hydroxide nemamwe makemikari kwemaawa maviri. Izvi zvakaburitsa lignin, morekuru rinopa huni ruvara rwayo, kubva muhuni. Mushure mezvo, vakadira epoxy resin pamusoro pechivharo chehuni, icho chakaita kuti chive chakasimba kakapetwa kashanu.

Chimwe chezvinhu zvinonakidza zvehuni "zvitsva" ndezvekuti inochengetedza chimiro uye nzira dzechisikigo dzakaumbwa payaive "chaiyo" huni. Aya ma microchannels anogona kuitisa mwenje sezvaanoita zvinovaka muviri sechikamu chechirimwa. "Muzvinyorwa zvechinyakare, mwenje unopararira," anodaro Hu. "Kana iwe ukawana chiitiko ichocho muhuni, chiedza chakawanda chichauya mumba mako."

Muchikamu chinotevera chetsvagurudzo, masayendisiti achaedza kugadzira nzira inovabvumira kuyera tekinoroji iyi, kuitira kuti vakwanise kugadzira matombo makuru ematanda akajeka anozoshandiswa zvakasiyana kubva pakugadzira mahwindo, zvekuvakisa uye fenicha. , nzira yese kune zvidiki zvikumbiro senge precision optics midziyo inowanzogadzirwa negirazi kana plastiki.
