Kodi mwakhala mukusaka njira ina yopangira mapulasitiki opangira mafuta?Msika wamasiku ano ukulowera kuzinthu zomwe zitha kuwonongeka komanso zokomera zachilengedwe zopangidwa kuchokera kuzinthu zongowonjezedwanso.

Zogulitsa za PLA zasintha mwachangu kukhala imodzi mwazinthu zodziwika bwino zomwe zitha kuwonongeka komanso zachilengedwe pamsika.Kafukufuku wa 2017 adapeza kuti kusintha mapulasitiki opangidwa ndi petroleum ndi mapulasitiki opangidwa ndi bio kumatha kuchepetsa kutulutsa mpweya wowonjezera kutentha m'mafakitale ndi 25%.

Kodi PLA ndi chiyani?

PLA, kapena polylactic acid, amapangidwa kuchokera ku shuga wonyezimira.PLA yambiri imapangidwa kuchokera ku chimanga chifukwa chimanga ndi chimodzi mwa shuga wotsika mtengo komanso wopezeka padziko lonse lapansi.Komabe, nzimbe, muzu wa tapioca, chinangwa, ndi zamasamba ndi zina.

Monga zinthu zambiri zokhudzana ndi chemistry, kupanga PLA kuchokera ku chimanga ndizovuta kwambiri.Komabe, zitha kufotokozedwa munjira zingapo zolunjika.

Kodi zinthu za PLA zimapangidwa bwanji?

Njira zopangira polylactic acid kuchokera ku chimanga ndi izi:

1. Wowuma wa chimanga woyamba uyenera kusinthidwa kukhala shuga kudzera munjira yamagetsi yotchedwa wet mphero.Mphero yonyowa imalekanitsa wowuma ndi maso.Asidi kapena ma enzyme amawonjezedwa pamene zigawozi zapatulidwa.Kenako, amatenthedwa kuti asinthe wowuma kukhala dextrose (aka shuga).

2. Kenaka, dextrose imafufuzidwa.Imodzi mwa njira zofala kwambiri zowotchera ndi kuwonjezeraLactobacillusmabakiteriya ku dextrose.Izi, nazonso, zimapanga lactic acid.

3. Asidiyo amasinthidwa kukhala lactide, dimer ya lactic acid.Mamolekyu a lactidewa amalumikizana pamodzi kuti apange ma polima.

4. Chotsatira cha polymerization ndi tiziduswa tating'ono ting'ono ta pulasitiki ya polylactic acid yomwe imatha kusinthidwa kukhala gulu laZinthu zapulasitiki za PLA.

Ubwino wa phukusi la chakudya:

• Alibe mankhwala owopsa ngati mafuta opangidwa ndi petroleum
• Amphamvu monga mapulasitiki ambiri ochiritsira
• Freezer-otetezeka
• Makapu amatha kutentha mpaka 110 ° F (ziwiya za PLA zimatha kutentha mpaka 200 ° F)
• Zopanda poizoni, zopanda mpweya, komanso 100% zongowonjezwdwa

PLA ndi yogwira ntchito, yotsika mtengo, komanso yokhazikika.Kusinthira kuzinthu izi ndi gawo lofunikira pakuchepetsa kuchuluka kwa kaboni mubizinesi yanu yazakudya.

JUDIN kampani ikhoza kupereka PLA yokutidwamakapu mapepala, mapepala a mapepala,mbale ya saladi ya pepalandi PLA cutlery,Makapu owonekera a PLA.
