Nkhani - Wowuma wa Mbaki Wopanda Biopíriastics: Udindo wake ndi chiyani?

M'moyo wathu watsiku ndi tsiku, zinthu zapulasitiki ndizosautsa. Komabe, nkhani zochulukitsa zachilengedwe zoyambitsidwa ndi zikhalidwe zachikhalidwe zapangitsa kuti anthu asanthulire njira zina zosatha. Apa ndipamene bioplastics amayamba kusewera. Pakati pawo, wowuma chimanga amasewera mbali yabwino monga gawo wamba mu bioplastics. Chifukwa chake, udindo waCornstarch mu bioplastics?

1.Kodi bioplastics ndi ziti?
Biopistics ndi pulasitiki zopangidwa ndi zinthu zokonzanso monga mbewu kapena tizilombo. Mosiyana ndi ma pulasitiki achikhalidwe, bioplastics zimapangidwa kuchokera ku zinthu zokonzanso, motero zimapangitsa kuti chilengedwe chochepa. Chiwindi chowuma, pakati pawo, chimagwiritsidwa ntchito ngati chimodzi mwazinthu zazikulu mu bioplastics.

2.Ingeni ya chimanga chowuma mu bioplastics

Chimanga chowuma amagwira ntchito zitatu zazikulu:
Cornstarch amatenga nawo gawo pakukulitsa, kukhazikika ndikuwongolera makonzedwe othandizira ku Bioplastics. Ndi polymer yomwe imatha kuphatikizidwa ndi ma piodergrador osasinthika kapena maofesi aopapo pulasitiki. Powonjezera zowonjezera zoyenera kwa chimanga, kuuma, kusinthasintha komanso kusasinthika kwa bioplastics kumatha kusinthidwa, kuwapangitsa kukhala oyenera ntchito zosiyanasiyana zofunsira.
Kulimbitsa Mphamvu Mwaluso: Kuphatikizika kwa wowuma wa chimanga kumatha kusintha kulimba mtima komanso kulimba kwa matenda a bioplastics, kumawapangitsa kukhala cholimba.

Kuwongolera magwiridwe antchito: Kukhalapo kwa chimanga kwa chimanga kumapangitsa bioplastics kukhala kovuta pokonza, kuwongolera kupanga zinthu zosiyanasiyana zopangidwa.

Kuphatikiza apo, chimanga cha chimanga chimakhala bwino kwambiri kubitalika. Pansi pazoyenera zachilengedwe, tizilombo tating'onoting'ono timatha kuphwanya chimanga chowuma chimakhala chosavuta kuphatikiza kwathunthu, kuwonongeka kwathunthu. Izi zimathandiza kuti bioplastics ikhale yobwezeretsedwa mwachilengedwe mutatha kugwiritsa ntchito, kuchepetsa kuipitsidwa kwa chilengedwe.

Komabe, chimanga chowuma chimaperekanso zovuta zina. Mwachitsanzo, kutentha kwambiri kapena mabizinesi apamwamba kwambiri, ma bioplastics amakonda kutaya kukhazikika, akukhudza moyo wawo ndi magwiridwe antchito. Kuti tithene ndi vutoli, asayansi akugwira ntchito popeza zowonjezera zatsopano kapena kukonza njira zopangira kuti zithandizire kutentha ndi chinyezi.

Kugwiritsa ntchito chimanga chowuma mu bioplastics kwina kumasiyananso kutengera zomwe mukufuna ndikugwiritsa ntchito zomaliza. Nawa zitsanzo zochepa:

Polylactic acid (pl): Pla ndi malo opezeka ndi chimanga kuchokera ku chimanga. Chingwe chowuma chimakhala ngati chakudya chopangira chactic acid, chomwe chimakhala polymer kuti apange pla. Pindulani ndi wowuma wa chimanga chikuwonetsa bwino zida zamakina, monga mphamvu zokhala ndi chidwi komanso kukana. Kuphatikiza apo, kuwonjezera kwa chimanga kumatha kukulitsa biodegradiity ya placegragradiity ya place, ndikupangitsa kukhala koyenera kwa mapulogalamu omwe nkhawa za chilengedwe ndizachikulu, mongamazira otayika, ma CACAGONCATION, ndi mafilimu a ulimi wa ulimi.

Ma polyhydroxyaxyaxyakolkaniates (PEM): PEMI ndi mtundu wina wa bioplastic yomwe imatha kupangidwa pogwiritsa ntchito burch yowuma ngati kaboni. Chingwe chowuma chimakhala chotupa ndi tizilombo tating'onoting'ono kuti apange pol sohydroxybutyrate (PHB), yomwe ndi mtundu wa nthawi. Phasi limalimbikitsidwa ndi chimanga chowuma chimakonda kukhala ndi zokhazikika bwino komanso zojambula zamakina. Izi zojambulazi zimapeza ntchito m'magawo osiyanasiyana, kuphatikizapo mapangidwe, zida zamankhwala, ndi ulimi.

Biopiostics yokhazikika: Nthawi zina wowuma, chimanga chimakodwa mwachindunji kukhala bioplastics popanda kufunika kwa ma polymerization. Biooplastics yokhazikika nthawi zambiri imakhala ndi kuphatikiza kwa chimanga, ma pulasitala, ma pulasitala, komanso zowonjezera kuti zitheke popanda kugwiritsa ntchito katundu. A Viopistics awa amagwiritsidwa ntchito pogwiritsa ntchito monga matumba otaya, zodzaza zakudya, komanso matebulo otaya.

Kuphatikizidwa ndi ma polima ena a biodegradge: Chn Wowuma amathanso kukhala ndi ma polimals, monga polyhhyhlactones mabipati (pcl), kupanga ma bioplastics omwe ali ndi zovomerezeka. Kuphatikiza uku kumakhala koyenera kwa mphamvu yamakina, kusinthasintha, ndi biodegradiity, ndikuwapangitsa kukhala oyenera mapulogalamu osiyanasiyana kuyambira kuzama.

4.Concord

Udindo wa chimanga wowuma mu bioplastics amapitilira magwiridwe; Zimathandizanso kuchepetsa kudalira mapulasitiki a petroleum odzipereka, kuyendetsa bwino chitukuko cha eco-ochezeka. Ndi ziphunzitso za ukadaulo, timayembekezera kuwona zinthu zina zatsopano za bioplastic zokhala ndi zinthu zokonzanso ngati chowuma cha chimanga.

Mwachidule, owuma chimanga amasewera mbali ya bioplastics, osati kungolimbitsa kukhazikika kwa mapulagisi komanso kulimbikitsa goodeza, pofuna kuchepetsa mphamvu zachilengedwe. Ndi kupita patsogolo kosalekeza kwaukadaulo ndi zatsopano, Bioplastics ndizotheka kuti tichite zambiri pobweretsa mapindu ake apadziko lapansi.
