Chengetedza Chengetedzo: Zvinyorwa zvinochengetedza zvakadero kubva muchinyorwa chekutanga uye hausi humbowo hutsva hwenyanzvi. Iyo yakatsanangurwa tsvagiridzo, maitiro, zvinhu uye zvinogoneka mashandisirwo hachisi chigadzirwa, tekinoroji yakatarwa, chitupa kana chirongwa cheSavo Kusić. Ikozvino inopihwa neveruzhinji yakatarisana nemahwindo etsika nemagonhi.
Tsananguro yenhoroondo yetsvagiridzo
Muti chivakwa chakasimba uye chinogoneka, asi sechinhu chero chipi zvacho, chine zvimhingamupinyi zvayo (chinoora nekufamba kwenguva, chinowora netsikidzi uye chinovhara kubuda kwechiedza).
Magirazi enguva dzose haasi nani. Vanoita nyore kufuratira chiedza uye vanobvumira simba guru kuti riyerere mukati kana kunze kwechivako. Mainjiniya vakawana akanakisa pane ese: huni hunoonekera.
Masayendisiti Liangbing Hu, Dr. Mingwei Zhu nevamwe vavo vekuYunivhesiti yeMaryland vakakwanisa kugadzira bhuroko remuti rive pachena, nokudaro vachiwana zvinhu zvinogona kushandiswa mukuvaka uye mumagetsi anoenderana nechiedza.
Masayendisiti akabvisa kubva muhuni molekuru rinoita kuti riome uye risvibe muruvara, ndokuwana masero asina ruvara ecellulose akazadzwa ne epoxy resin, nokudaro zvichikonzera huni hunonyanya kujeka.
“Izvi zvinogona kushandiswa mumotokari nokuti huni huri pachena uye hwakasimba zvikuru,” akadaro Dr. Zhu, munyori wekutanga wekudzidza. “Unogona zvakare kuishandisa sechinhu chakasarudzika chekuvakisa.”
Nekubvisa pendi nemakemikari, huni dzakabva dzajeka, asi dzine simba zvakare uye insulator iri nani pane girazi, uye ine midziyo ye biodegradability iri nani pane plastiki.
Maitiro uye zvivakwa zvinotaurwa muchinyorwa
Maitirwo aita kuti huni dzive pachena akatanga nekuifashaidza mumvura yakasanganiswa nesodium hydroxide nemamwe makemikari kwemaawa angangoita 2. Izvi zvakaburitsa lignin, morekuru rinopa huni ruvara rwayo, kubva muhuni. Mushure mezvo, vakadira epoxy resin pamusoro pechivharo chehuni, icho chakaita kuti chiwedzere kusimba zvakapetwa kana kashanu.
Chimwe chezvinhu zvinonakidza zvehuni “nyowani” ndechekuti yakachengeta 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 ukawana mhedzisiro muhuni, chiedza chakawanda chichauya mumba mako.”
Zvishandiso zvinogoneka zvakanyorwa musource
Mumatanho anotevera ekutsvagisa, masayendisiti anoedza kugadzira nzira inovabvumira kuyera tekinoroji iyi, kuitira kuti zvidhinha zvihombe zvehuni zvinoonekera zvigadzirwe izvo zvinozoshandiswa zvakasiyana kubva pakugadzira mahwindo, zvekuvakisa uye fenicha, kusvika kumashandisirwo madiki akadai sekunyatsoona michina inogadzirwa negirazi kana plastiki.
