Nkhani - Kuvumbulutsa Wowuma wa Chimanga mu Bioplastics: Udindo Wake Ndi Chiyani?

M'moyo wathu watsiku ndi tsiku, zinthu zapulasitiki zili paliponse. Komabe, kuchuluka kwa zinthu zachilengedwe zomwe zimayambitsidwa ndi mapulasitiki achikhalidwe zapangitsa anthu kufunafuna njira zina zokhazikika. Apa ndipamene bioplastics imayamba kugwira ntchito. Mwa iwo, wowuma wa chimanga amatenga gawo lofunikira kwambiri mu bioplastics. Ndiye, udindo wake ndi chiyani kwenikwenicornstarch mu bioplastics?

1.Kodi Bioplastics ndi chiyani?
Bioplastics ndi mapulasitiki opangidwa kuchokera kuzinthu zongowonjezedwanso monga zomera kapena tizilombo tating'onoting'ono. Mosiyana ndi mapulasitiki achikhalidwe, ma bioplastics amapangidwa kuchokera kuzinthu zongowonjezedwanso, zomwe zimapangitsa kuti chilengedwe chisawonongeke. Wowuma wa chimanga, pakati pawo, amagwiritsidwa ntchito ngati chimodzi mwazinthu zazikulu mu bioplastics.

2. Udindo wa Chimanga Wowuma mu Bioplastics

Wowuma wa chimanga amagwira ntchito zazikulu zitatu:
Cornstarch imathandizira kukulitsa, kukhazikika komanso kukonza zinthu zopangira ma bioplastics. Ndi polima yomwe imatha kuphatikizidwa ndi ma polima ena osawonongeka kapena mapulasitiki kuti apange zokhazikika. Powonjezera zowonjezera zowonjezera ku wowuma wa chimanga, kuuma, kusinthasintha komanso kuwonongeka kwa bioplastics kumatha kusinthidwa, kuwapanga kukhala oyenera pazosiyanasiyana zogwiritsira ntchito.
Kupititsa patsogolo Mphamvu zamakina: Kuphatikizika kwa wowuma wa chimanga kumatha kukulitsa kulimba ndi kulimba kwa bioplastics, kuwapangitsa kukhala olimba.

Kupititsa patsogolo Magwiridwe Antchito: Kukhalapo kwa wowuma wa chimanga kumapangitsa bioplastics kukhala yofewa kwambiri panthawi yokonza, kumathandizira kupanga zinthu zosiyanasiyana zowoneka bwino.

Kuphatikiza apo, wowuma wa chimanga ali ndi biodegradability yabwino kwambiri. Pansi pazikhalidwe zoyenerera zachilengedwe, tizilombo tating'onoting'ono titha kuphwanya wowuma wa chimanga kukhala zinthu zosavuta, zomwe pamapeto pake zimatha kuwonongeka kwathunthu. Izi zimathandiza kuti ma bioplastics apangidwenso mwachilengedwe akagwiritsidwa ntchito, kuchepetsa kuipitsidwa kwa chilengedwe.

Komabe, wowuma wa chimanga amakhalanso ndi zovuta zina. Mwachitsanzo, m'malo otentha kwambiri kapena okhala ndi chinyezi chambiri, ma bioplastics amatha kutaya kukhazikika, zomwe zimakhudza moyo wawo komanso momwe amagwirira ntchito. Kuti athane ndi vutoli, asayansi akuyesetsa kupeza zowonjezera kapena kukonza njira zopangira kuti apititse patsogolo kukana kutentha komanso kukana chinyezi kwa bioplastics.

3.Magwiritsidwe a Chimanga Wowuma mu Specific Bioplastics

Kugwiritsiridwa ntchito kwa wowuma wa chimanga mu bioplastics yeniyeni kumasiyana malinga ndi zomwe mukufuna komanso kugwiritsa ntchito komaliza. Nazi zitsanzo zingapo:

Polylactic Acid (PLA): PLA ndi bioplastic yomwe imachokera ku wowuma wa chimanga. Wowuma wa chimanga amagwira ntchito ngati chakudya chopangira lactic acid, yomwe imapangidwa ndi polymerized kupanga PLA. PLA yolimbikitsidwa ndi wowuma wa chimanga imawonetsa kusinthika kwamakina, monga kulimba kwamphamvu komanso kukana. Kuphatikiza apo, kuwonjezera kwa chimanga wowuma kumatha kukulitsa kuwonongeka kwa PLA, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe kukhudzidwa ndi chilengedwe ndikofunikira, mongazodula zotayidwa, kulongedza zakudya, ndi mafilimu a mulch.

Polyhydroxyalkanoates (PHA): PHA ndi mtundu wina wa bioplastic womwe ungapangidwe pogwiritsa ntchito chimanga chowuma ngati gwero la kaboni. Wowuma wa chimanga amafufuzidwa ndi tizilombo toyambitsa matenda kuti apange polyhydroxybutyrate (PHB), yomwe ndi mtundu wa PHA. Ma PHA olimbikitsidwa ndi wowuma wa chimanga amakhala ndi kukhazikika kwamafuta komanso makina amakina. Ma bioplastic awa amapeza ntchito m'magawo osiyanasiyana, kuphatikiza ma CD, zida zamankhwala, ndi ulimi.

Ma Bioplastics Otengera Wowuma: Nthawi zina, wowuma wa chimanga amasinthidwa mwachindunji kukhala ma bioplastics popanda kufunikira kwa njira zina zowonjezera ma polymerization. Ma bioplastics opangidwa ndi starch nthawi zambiri amakhala ndi zosakaniza za chimanga chowuma, zopangira mapulasitiki, ndi zowonjezera kuti zithandizire kusinthika komanso kugwiritsa ntchito komaliza. Ma bioplastics awa amagwiritsidwa ntchito ngati zikwama zotayidwa, zotengera zakudya, ndi ma tableware otayika.

Kuphatikiza ndi Ma polima Ena Osawonongeka: Wowuma wa chimanga amathanso kusakanikirana ndi ma polima ena owonongeka, monga polyhydroxyalkanoates (PHA), polycaprolactone (PCL), kapena polybutylene adipate-co-terephthalate (PBAT), kuti apange bioplastics yokhala ndi zida zogwirizana. Zophatikizika izi zimapereka mphamvu zamakina, kusinthasintha, komanso kuwonongeka kwachilengedwe, zomwe zimawapangitsa kukhala oyenera ntchito zosiyanasiyana kuyambira pakuyika mpaka ulimi.

4.Mapeto

Udindo wa wowuma wa chimanga mu bioplastics umapitilira kupititsa patsogolo ntchito; zimathandizanso kuchepetsa kudalira mapulasitiki achikhalidwe opangidwa ndi petroleum, ndikuyendetsa chitukuko cha zinthu zachilengedwe. Ndi kupita patsogolo kwaukadaulo, tikuyembekeza kuwona zinthu zatsopano za bioplastic zochokera kuzinthu zongowonjezedwanso ngati chimanga wowuma.

Mwachidule, wowuma wa chimanga amagwira ntchito zambiri mu bioplastics, osati kumangowonjezera kukhazikika kwa mapulasitiki komanso kulimbikitsa kuwonongeka kwawo, potero kumachepetsa kuwonongeka kwa chilengedwe. Ndi kupita patsogolo kwaukadaulo komanso luso laukadaulo, ma bioplastics ali okonzeka kutenga gawo lalikulu pakubweretsa zopindulitsa ku chilengedwe chapadziko lapansi.
