Wanga uchitsvaga imwe nzira yepetroleum-based mapurasitiki uye kurongedza?Musika wemazuva ano uri kuramba uchienda kune biodegradable uye eco-hushamwari zvigadzirwa zvakagadzirwa kubva kune zvinogonekazve zviwanikwa.

Zvigadzirwa zvePLA zvakakurumidza kuve imwe yeanonyanya kufarirwa biodegradable uye zvakatipoteredza-ane hushamwari sarudzo pamusika.Ongororo yemuna 2017 yakawana kuti kutsiva mapurasitiki ane petroleum nemapurasitiki ane bio-based anogona kuderedza kuburitswa kwemaindasitiri egreenhouse gasi ne25%.

Chii chinonzi PLA?

PLA, kana polylactic acid, inogadzirwa kubva kune chero shuga inovirisa.PLA zhinji inogadzirwa nechibage nekuti chibage chimwe cheshuga dzakachipa uye dzinowanikwa pasi rose.Zvisinei, nzimbe, mudzi wetapioca, mufarinya, uye sugar beet pulp ndezvimwe zvingasarudzwa.

Kufanana nezvinhu zvakawanda zvine chekuita nemakemikari, maitiro ekugadzira PLA kubva muchibage akaoma.Zvisinei, inogona kutsanangurwa mumatanho mashoma akatwasuka.

Zvigadzirwa zvePLA zvinogadzirwa sei?

Matanho ekutanga ekugadzira polylactic asidhi kubva kuchibage ndeaya anotevera:

1. Chekutanga chibage starch inofanira kuchinjwa kuva shuga kuburikidza nema mechanical process inonzi wet milling.Kugaya kwakanyorova kunopatsanura sitachi nembeu.Acid kana ma enzyme anowedzerwa kana zvikamu izvi zvaparadzaniswa.Zvadaro, vanopisa kushandura starch mu dextrose (aka shuga).

2. Zvadaro, dextrose inoviriswa.Imwe yedzakajairika nzira yekuvirisa inosanganisira kuwedzeraLactobacillusmabhakitiriya kune dextrose.Izvi, zvakare, zvinogadzira lactic acid.

3. Iyo lactic acid inozoshandurwa kuita lactide, ring-form dimer yelactic acid.Aya mamorekuru elactide anobatana pamwechete kugadzira mapolymer.

4. Mhedzisiro yepolymerization zvimedu zvidiki zvepolylactic acid epurasitiki inogona kushandurwa kuita muunganidzwa we.PLA plastiki zvigadzirwa.

Kuiswa kwechikafu kunobatsira:

• Havana makemikari anokuvadza akafanana nemafuta epetroleum-based products
• Akasimba semapurasitiki akawanda akajairika
• Freezer-yakachengeteka
• Makapu anogona kubata tembiricha inosvika 110°F (PLA midziyo inogona kubata tembiricha kusvika 200°F)
• Isiri-chepfu, kabhoni-yakarerekera, uye 100% inogona kuvandudzwa

PLA inoshanda, inodhura, uye inogadzikana.Kuita shanduko kune izvi zvigadzirwa idanho rakakosha rekudzikisa bhizinesi rako rekudya kabhoni tsoka.

JUDIN kambani inogona kupa PLA yakavharwamapepa makapu, mabhokisi emapepa,pepa saladhi ndirouye PLA cutlery,PLA makapu akajeka.
