Nrog rau txoj kev loj hlob ntawm biotechnology niaj hnub no, ntau thiab ntau cov xim tau them rau biodegradable plastics, uas tau dhau los ua ib tiam tshiab ntawm kev tshawb fawb thiab kev loj hlob hotspot.
A. Raws li lub hauv paus ntsiab lus ntawm degradable mechanism
1. Photodegradable plastics:
Ib tug photosensitizer ntxiv rau cov yas kom maj mam decompose nws nyob rau hauv tshav ntuj.
2. Biodegradable plastics:
Cov yas uas decompose tag nrho rau hauv cov tebchaw uas tsis muaj molecular nyob rau hauv qhov kev txiav txim ntawm cov kab mob.
3. Lub teeb / biodegradable hnab yas:
Ib hom yas uas ua ke nrog photodegradation thiab microbiota, muaj cov yam ntxwv ntawm ob qho tib si photodegradation thiab microbiota degradation thiaj li ua tiav kev degradation.
4. Dej-degradable yas:
Ntxiv cov dej-absorbing tshuaj rau cov yas, uas tuaj yeem yaj hauv dej tom qab siv.
GTMSMARTPla Biodegradable Thermoforming Tshuab yog nyob rau hauv qeb ntawm biodegradable.
B. Raws li cov khoom siv raw
Degradable cov ntaub ntawv muab rho tawm los ntawm biomass peev txheej (xws li cog fibers, starch, thiab lwm yam).
1. Petrochemical raws li plastics (xws li roj av thiab natural gas.)
2. Bio-raws li plastics (xws li cog fibers, starch, thiab lwm yam).
GTMSMARTBiodegradable Food Container Making Machine yog nyob rau hauv qeb ntawm bio-based plastics.
C. Raws li cov nyhuv degradation
1. Tag nrho degradation
2. Ib nrab degradation
GTMSMARTPLA Degradable Yas Thermoforming Tshuabyog nyob rau hauv qeb ntawm Total degradation.
D. Raws li kev siv kev faib tawm
1. Ib puag ncig (natural) degradable plastics:
Namely plastics tshiab, photodegradable plastics, biodegradable plastics, photooxide / biocomprehensive degradable plastics, thermoplastic starch resin degradable plastics, Co2-raws li biodegradable yas
2. Biodegradable (ib puag ncig) plastics:
Siv rau hauv cov tshuaj rau kev phais sutures, pob txha pob txha, thiab lwm yam.
GTMSMARTPLA Thermoforming Tshuabs yog nyob rau hauv qeb ntawm Environmental (natural) degradable plastics.
