Kodi pali kusiyana kotani pakati pa matumba osawonongeka ndi matumba owonongeka kwambiri?

Anzanu ambiri amafunsa kuti pali kusiyana kotani pakati pa zikwama zosawonongeka ndi matumba owonongeka kwambiri? Kodi sichofanana ndi thumba lopanda kanthu? Zolakwika, pali kusiyana pakati pa matumba osawonongeka ndi matumba owonongeka kwambiri.

Matumba owonongeka, tanthauzo lake ndikuti akhoza kukhala odetsedwa, koma matumba osowa a Paketi amagawidwa "komanso" kuwonongeka kwathunthu ". Kodi pali kusiyana kotani? Pitilizani kuwerenga chidziwitso chochepa choperekedwa ndi aluli.

Matumba osawonongeka amatanthauza kuwonjezera zowonjezera (monga wowuma, wowuma wosinthika, mavidiyo ena, a Biodecgrants Matumba apulasitiki.

Chikwama chokwanira chopepuka chimatanthawuza kuti chikwama cha pulasitiki cha pulasitiki chimawonongeka m'madzi ndi kaboni dayokisaidi. Gwero lalikulu la zinthu zonyansa izi zimakonzedwa kuchokera ku chimanga, chinangwa, ndi zina mwa lactic. Polylactic acid (pl) ndi mtundu watsopano wa gawo lapansi lazomwe zakukonzanso. Zinthu zopukutira zimapangidwa kuti zipeze shuga, kenako nkutupa kwa glucose ndi zovuta zina zopanga zoyera kwambiri acid, zomwe zimapangidwa ndi makenti a mankhwala a mankhwala. Mafuta olemera a polylactic acid. Ili ndi biodegradiilicediilicediilicedibitation, ndipo imatha kuwonongeka kwathunthu ndi microorganisms mu chilengedwe momwe mungagwiritsire ntchito, pamapeto pake ndikupanga zotchinga malo, zomwe ndizothandiza kuteteza chilengedwe ndipo ndi chinthu chothandiza anthu ogwira ntchito. Pakadali pano, zinthu zazikuluzikulu za thumba lopanda tanthauzo limapangidwa ndi pbat, lomwe limatha kuwola m'madzi ndi kaboni dayokisi mu miyezi 3-0-70, popanda kuipitsidwa ndi chilengedwe.

Chifukwa chiyani pbat iyenera kuwonjezeredwa? Aruli akuyesa mainjiniya wamankhwala adathandizira wolemba kuti awamasulire. PBAT ndi wopopera wa adipic acid, 1,4-yitanediiol ndi terephthalic acid. Ndi kaphatikizidwe ka mankhwala komwe kumatha kukhala kokwanira. A Aliphatic-armatic polymer a pbat ali ndi kusinthasintha kosinthasintha ndipo amatha kugwiritsidwa ntchito potuluka filimu, kuwomba akuwumba, akutukuka ndi njira zina zoumba. Cholinga chophatikizira plu ndi pbat ndikusintha mphamvu, kuthira bwino ndikupanga mawonekedwe a pla. Pla ndi pbat ndizosagwirizana, kotero kusankha kagulu koyenera kumatha kusintha magwiridwe antchito.

Onani apa kuti mumvetsetse kusiyana pakati pa matumba owonongeka ndi matumba owonongeka kwathunthu.

Chifukwa chiyani pbat iyenera kuwonjezeredwa? Opanga zosinthika zosinthika ali pano kuti afotokozere kuti PBAT ndi wopopera wa adipic ad, 1,4-fire4alic, ndi mafuta onunkhira bwino kwambiri omwe amatha kukhala bwino kwambiri.
