Qhov no coj koj kev nkag siab tob txog cov hnab ntim khoom biodegradable!
Raws li ntau lub tebchaws txwv tsis pub siv cov hnab yas, cov hnab yas uas lwj tau raug siv hauv ntau lub lag luam. Kev tiv thaiv ib puag ncig yog ib qho kev hloov pauv tsis zam. Puas muaj cov chaw uas pom zoo kom siv cov hnab yas uas lwj tau? Cov khoom twg uas cov hnab yas uas lwj tau siv tau? Kuv ntseeg tias qhov no yog qhov uas ntau tus neeg siv khoom xaj cov hnab yas uas lwj tau tag nrho xav paub. Niaj hnub no, OK Packaging tsim cov hnab yas uas lwj tau
1. Cov ntim khoom uas lwj tau yog dab tsi?
Lub hnab yas uas lwj tau yog ib hom hnab yas uas tuaj yeem lwj tag nrho cov dej, carbon dioxide thiab lwm yam khoom me me. Lub hauv paus tseem ceeb ntawm cov khoom siv lwj no yog polylactic acid (PLA), uas yog rho tawm los ntawm pob kws thiab cassava. Planet (PLA) yog ib hom khoom siv bio-based tshiab thiab cov khoom siv rov ua dua tshiab. Tom qab fermentation ntawm glucose thiab qee hom kom tsim cov kua qaub lactic acid purity siab, poly (lactic acid) nrog qee qhov hnyav molecular tau synthesized los ntawm txoj kev tshuaj synthesis, thiab tom qab ntawd glucose tau txais los ntawm saccharification. Cov khoom no muaj biodegradability zoo thiab tuaj yeem lwj tag nrho los ntawm cov kab mob ntuj tom qab siv los tsim cov pa roj carbon dioxide thiab dej, uas yuav tsis ua rau ib puag ncig puas tsuaj tom qab siv. Nws muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab suav tias yog cov khoom siv zoo rau ib puag ncig.
Tam sim no, cov khoom siv tseem ceeb ntawm cov hnab yas uas lwj tau yog PLA + PBAT, uas tuaj yeem lwj tag nrho mus rau hauv dej thiab carbon dioxide hauv 3-6 lub hlis nyob rau hauv qhov xwm txheej ntawm kev ua composting (60-70 degrees). Tsis muaj kuab paug rau ib puag ncig. Vim li cas thiaj ntxiv PBAT? PBAT yog ib qho copolymer ntawm adipic acid, 1, 4-butanediol thiab terephthalic acid, uas yog ib qho biodegradable tag nrho chemically synthesized aliphatic thiab aromatic polymer. PBAT muaj kev ywj pheej zoo heev thiab tuaj yeem siv rau zaj duab xis extrusion, tshuab molding, extrusion txheej thiab lwm yam txheej txheem molding. Kev sib xyaw ntawm PLA thiab PBAT yog tsim los txhim kho qhov toughness, biodegradability thiab formability ntawm PLA.
2. Cov chaw tsim cov hnab yas uas lwj tau thiab muaj lub koob npe zoo nyob qhov twg?
Hauv kev lag luam ntawm cov hnab yas uas lwj tau, nws tau tsim ib lub tshuab cua zaj duab xis tshwj xeeb, tshuab luam ntawv, tshuab txiav hnab, tshuab granule pov tseg thiab ntau yam kab ntau lawm rau cov hnab yas uas lwj tau. Cov khoom lag luam suav nrog cov hnab tshos, hnab khib nyiab, hnab tes, hnab khaub ncaws, hnab kho vajtse, hnab tshuaj pleev ib ce, hnab khoom noj, hnab daim npav taub hau, hnab ntawv kraft / PLA composite, thiab lwm yam, zoo ruaj khov, ua haujlwm tau zoo, luam ntawv zoo heev, tsis muaj dej noo, tsis muaj tshuaj lom, kaw zoo, ncab zoo, zoo nkauj, tiv thaiv ib puag ncig.
Ok ntim khoom ua raws li lub tswv yim ntawm kev tiv thaiv ib puag ncig thiab cog lus rau kev txhim kho kom ruaj khov ntawm ib puag ncig, tsim tau zoo yog qhov tsim nyog rau kev lag luam ntim khoom thiab cov khoom noj khoom haus cov khoom siv biodegradable tag nrho, muaj kev paub nplua nuj hauv kev lag luam ntim khoom thiab teb rau kev faib cov khib nyiab, txhawb kev siv cov peev txheej dua tshiab, thiab nquag tsim cov khoom noj khoom haus-qib biodegradable tag nrho.
3. Cov khoom twg siv tau rau hauv cov hnab yas uas lwj tau?
Cov hnab yas uas lwj tau siv dav hauv cov khaub ncaws, khaub ncaws xaws, khaub ncaws, ntaub, khoom noj, khoom siv kho vajtse, khoom siv hluav taws xob, tshuaj pleev ib ce thiab lwm yam lag luam. Cov hnab yas uas lwj tau muaj ntau yam qauv kaw, xws li pob txha nplaum, zipper, daim kab xev, thiab lwm yam, thiab cov hnab yas uas lwj tau sib xyaw nrog ntawv, uas tuaj yeem quav lub cev hauv qab. Tam sim no, cov hnab yas uas lwj tau nkag mus rau txhua qhov chaw ntawm lub neej, thiab muaj ntau yam qauv; Yav tom ntej, cov hnab yas uas lwj tau yuav dhau los ua cov khoom lag luam tseem ceeb ntawm kev lag luam ntim khoom.
