Kodi pulasitiki yowonongeka ngati PLA ndi PBAT ndi chiyani?

Pulasitiki yowonongekandi mtundu watsopano wa zinthu zapulasitiki.Panthawi yomwe chitetezo cha chilengedwe chikukhala chofunikira kwambiri, pulasitiki yowonongeka imakhala ECO ndipo ikhoza kukhala m'malo mwa PE / PP m'njira zina.

Pali mitundu yambiri ya pulasitiki yowonongeka, yomwe imagwiritsidwa ntchito kwambiri ndi ziwiriPLAndiMtengo PBAT, Maonekedwe a PLA nthawi zambiri amakhala achikasu, zopangira zimachokera ku mbewu monga chimanga, nzimbe etc. Maonekedwe a PBAT nthawi zambiri amakhala oyera, zopangira zimachokera ku mafuta.

PLA imakhala ndi kukhazikika kwamafuta abwino, kukana bwino kwa zosungunulira, ndipo imatha kukonzedwa m'njira zambiri, monga extrusion, kupota, kutambasula, jekeseni, kuumba nkhonya.PLA itha kugwiritsidwa ntchito ku: udzu, mabokosi a chakudya, nsalu zosalukidwa, nsalu zamakampani ndi anthu wamba.

PBAT ilibe ductility wabwino ndi elongation panthawi yopuma, komanso kukana kwabwino kwa kutentha ndi magwiridwe antchito.Itha kugwiritsidwa ntchito mu Packaging, tableware, mabotolo odzikongoletsera, mabotolo amankhwala, mafilimu aulimi, mankhwala ophera tizilombo ndi feteleza zomwe zimatulutsidwa pang'onopang'ono.

Pakali pano, mphamvu yopanga PLA yapadziko lonse ndi pafupifupi matani 650000, mphamvu ya China ili pafupi matani 48000 / chaka, koma ku China ntchito za PLA zomwe zikumangidwa ndi pafupifupi matani 300000 / chaka, ndipo mphamvu zopanga nthawi yayitali zimakhala pafupifupi matani 2 miliyoni / chaka.

Kwa PBAT, mphamvu yapadziko lonse lapansi ndi pafupifupi matani 560000, mphamvu yaku China ndi pafupifupi 240000, mphamvu yokonzekera nthawi yayitali ndi pafupifupi matani 2 miliyoni / chaka, China ndiye wopanga wamkulu wa PBAT padziko lapansi.
