Qhov coj koj nkag siab tob txog biodegradable ntim hnab!
Raws li ntau thiab ntau lub teb chaws txwv cov hnab yas, cov hnab biodegradable tau siv nyob rau hauv ntau thiab ntau kev lag luam. Kev tiv thaiv ib puag ncig yog ib qho kev inevitable. Puas muaj tej qhov chaw uas pom zoo siv cov hnab yas biodegradable? Cov khoom twg tuaj yeem siv cov hnab yas biodegradable? Kuv ntseeg tias qhov no yog qhov ntau tus neeg siv khoom xaj kom tag nrho cov hnab yas biodegradable xav paub. Niaj hnub no, OK Ntim tsim cov hnab yas degradable
1. Dab tsi yog biodegradable ntim?
Biodegradable hnab yas yog ib hom hnab yas uas tuaj yeem degrade dej, carbon dioxide thiab lwm yam me me molecules. Lub hauv paus ntsiab lus ntawm cov khoom degradable no yog polylactic acid (PLA), uas yog muab rho tawm los ntawm pob kws thiab cassava. Planet (PLA) yog ib yam tshiab ntawm cov khoom siv bio-raws li thiab txuas ntxiv biodegradable khoom. Tom qab fermentation ntawm qabzib thiab ib co hom los tsim cov purity lactic acid, poly (lactic acid) nrog ib tug tej yam molecular hnyav tau synthesis los ntawm chemical synthesis method, thiab ces qabzib tau los ntawm saccharification. Cov khoom no muaj biodegradability zoo thiab tuaj yeem ua rau tag nrho degraded los ntawm cov kab mob hauv lub cev tom qab siv los tsim cov pa roj carbon dioxide thiab dej, uas yuav tsis ua phem rau ib puag ncig tom qab siv. Nws muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab suav tias yog cov khoom siv ib puag ncig.
Tam sim no, cov khoom siv roj ntsha tseem ceeb ntawm cov hnab yas degradable yog tsim los ntawm PLA + PBAT, uas tuaj yeem decomposed tag nrho rau hauv dej thiab carbon dioxide nyob rau hauv 3-6 lub hlis nyob rau hauv cov xwm txheej ntawm composting (60-70 degrees). Tsis muaj kuab paug rau ib puag ncig. Vim li cas thiaj ntxiv PBAT? PBAT yog ib tug copolymer ntawm adipic acid, 1, 4-butanediol thiab terephthalic acid, uas yog ib tug kiag li biodegradable tshuaj synthesized aliphatic thiab aromatic polymer. PBAT muaj qhov ua tau zoo heev thiab tuaj yeem siv rau kev ua yeeb yaj kiab extrusion, tshuab moulding, extrusion txheej thiab lwm yam txheej txheem molding. Kev sib xyaw ntawm PLA thiab PBAT yog tsim los txhim kho toughness, biodegradability thiab formability ntawm PLA.
2. Qhov twg yog cov chaw tsim khoom ntawm biodegradable hnab nrog lub koob npe nrov?
Nyob rau hauv lub tshav pob ntawm biodegradable hnab yas, nws tau tsim ib tug tshwj xeeb zaj duab xis tshuab tshuab, tshuab luam ntawv, hnab txiav tshuab, pov tseg recycling granulator thiab ntau yam mature ntau lawm kab rau biodegradable hnab yas. Cov khoom lag luam npog lub hnab tsho khuam, hnab khib nyiab, hnab tes, hnab khaub ncaws, hnab kho vajtse, hnab tshuaj pleev ib ce, hnab ntim khoom noj, daim npav lub taub hau hnab, kraft ntawv / PLA cov hnab ntim khoom, thiab lwm yam. , puncture pov thawj, tsis muaj tshuaj lom, zoo sealing, zoo stretching, zoo zoo nkauj, kev tiv thaiv ib puag ncig.
Ok ntim adhering rau lub tswv yim ntawm kev tiv thaiv ib puag ncig thiab tau cog lus rau kev tsim kho kom ruaj khov ntawm ecological ib puag ncig, tsim tau zoo yog tsim rau kev lag luam ntim thiab cov khoom noj khoom haus biodegradable tag nrho cov ntaub ntawv thiab cov khoom, muaj kev nplua nuj nyob rau hauv kev lag luam ntawm ntim thiab teb rau cov khib nyiab cais, txhawb nqa cov peev txheej rov siv dua, thiab nquag tsim cov khoom noj khoom haus-qib biodegradable tag nrho.
3. Cov khoom twg tuaj yeem siv lub hnab biodegradable?
Biodegradable hnab yas yog dav siv hauv lub tsho, knitting, khaub ncaws, khaub ncaws, textiles, khoom noj khoom haus, kho vajtse, electronics, tshuaj pleev ib ce thiab lwm yam lag luam. Cov hnab yas biodegradable muaj ntau qhov kev sib khi tsim, xws li cov pob txha nplaum, zipper, daim kab xev, thiab lwm yam, thiab cov hnab yas biodegradable yog compounded nrog ntawv, uas tuaj yeem quav hauv qab. Tam sim no, cov hnab yas biodegradable tau nkag mus rau txhua qhov chaw ntawm lub neej, thiab muaj ntau yam qauv; Nyob rau hauv lub neej yav tom ntej, biodegradable hnab yas yuav dhau los ua cov khoom lag luam ntawm kev lag luam ntim khoom.
