Nrog rau txoj kev loj hlob sai ntawm kev lag luam ntim, kev tsim kho tshiab ntawm cov ntaub ntawv siv thev naus laus zis thiab kev mloog zoo ntawm tib neeg lub tswv yim tiv thaiv ib puag ncig, ntau thiab ntau lub hnab yas yog ua los ntawm cov ntaub ntawv zoo ib puag ncig.Yog hais tias raws li cov khoom siv raw, ces peb pawg tseem ceeb. ntawm cov hnab yas ib puag ncig: cov yas rov ua dua tshiab, cov yas degradable thiab edible yas.
Recycled yas
Recycled yas yog siv cov yas rov qab, los ntawm kev sib tsoo tshuab, kom ua tiav cov yas rov qab siv dua.
Recycled yas hais txog cov khoom siv yas uas tau txais dua tom qab ua cov yas pov tseg los ntawm kev siv lub cev los yog tshuaj xws li pretreatment, melting granulation thiab hloov kho, uas yog siv cov yas rov qab.
Qhov zoo tshaj plaws ntawm cov yas rov ua dua tshiab yog twv yuav raug nqi pheej yig dua li cov khoom siv tshiab, txawm hais tias nws yog nyob rau ntawm tag nrho cov kev ua tau zoo thiab cov khoom tsis zoo li cov khoom tshiab muaj zog, tab sis peb tsis tas yuav siv ntau yam khoom ua rau cov khoom thiab kev ua tau zoo ntawm tag nrho cov khoom siv zoo los ua kom nws, yog li ntawd nkim ntau ntau yam tsis tsim nyog, thiab cov khoom siv rov ua dua yog qhov sib txawv, raws li kev xav tau sib txawv, tsuas yog yuav tsum tau ua qee yam ntawm tus cwj pwm, tuaj yeem ua rau cov khoom sib xws. , kom tsis txhob poob ntawm cov peev txheej.
Yas degradable
Cov plastics degradable yog hais txog cov yas uas yooj yim degraded nyob rau hauv ib puag ncig ntuj vim qhov sib ntxiv ntawm qee yam additives (xws li hmoov txhuv nplej siab, hloov cov hmoov txhuv nplej siab los yog lwm yam cellulose, photosensitizer, biodegradation agent, thiab lwm yam) hauv cov txheej txheem ntau lawm.Degradable plastics poob rau hauv plaub pawg loj:
1. Biodegradable yas
Qhuav, tsis tas yuav zam lub teeb, muaj ntau yam kev siv, tsis tsuas yog siv tau rau kev ua liaj ua teb yas zaj duab xis, lub hnab ntim khoom, thiab siv dav hauv kev lag luam tshuaj.Nrog rau txoj kev loj hlob ntawm niaj hnub biotechnology, biodegradable plastics tau them nyiaj ntau thiab ntau dua thiab dhau los ua qhov chaw kub tshiab hauv kev tshawb fawb thiab kev loj hlob.
2.Photodegradable yas
Ib tug photosensitizer ntxiv rau cov yas kom maj mam zom nws hauv qab hnub ci.Nws belongs rau tiam dhau los ntawm degradable plastics, thiab nws qhov tsis zoo yog lub sij hawm degradation yog unpredictable vim lub hnub ci thiab huab cua hloov, yog li nws yog tsis yooj yim sua los tswj lub sij hawm degradation.
3. Dej degradation ntawm yas
Ntxiv cov khoom nqus dej hauv cov yas, tom qab siv, muab pov tseg hauv dej tuaj yeem yaj, feem ntau yog siv rau hauv cov tshuaj thiab cov khoom siv kho mob (xws li cov hnab looj tes kho mob), yooj yim los rhuav tshem thiab tshuaj tua kab mob.
4. Lub teeb / biodegradable yas
Photodegradation thiab microbial ua ke ntawm ib chav kawm ntawm cov yas, nws muaj ob lub teeb thiab microbial degradation ntawm cov yam ntxwv yas.
Khoom noj khoom haus yas
Khoom noj khoom haus yas yog ib hom kev ntim khoom noj, uas yog, ntim khoom noj, feem ntau muaj cov hmoov txhuv nplej siab, protein, polysaccharide, rog, cov khoom sib xyaw, siv dav hauv xws li hnab yas, ntim zaj duab xis, ntim cov ntsiab lus siab, ntim khoom noj, ntim pastry, seasoning ntim, thiab lwm yam.
Nrog rau txoj kev loj hlob ntawm kev lag luam khoom noj niaj hnub, ntim khoom noj yog hloov kho tas li.Ib hom tshiab ntawm cov khoom ntim khoom siv thev naus laus zis, ntim khoom noj, uas tuaj yeem txhim kho qhov tsis sib xws ntawm cov khoom ntim thiab kev tiv thaiv ib puag ncig, sawv tawm.Cov khoom ntim khoom noj tau hais txog cov khoom ntim tshwj xeeb uas tuaj yeem hloov mus rau hauv cov khoom siv raw khoom noj rau tsiaj lossis tib neeg tom qab kev ua haujlwm ntawm kev ntim khoom tiav.Cov khoom ntim khoom noj khoom haus yog ib hom ntim khoom tsis muaj pov tseg, yog ib yam khoom siv los tiv thaiv ib puag ncig.
