A. yog dab tsibiodegradable tawv:
Biodegradable tawv txhais tau hais tias tawv tawv thiab hluavtaws tawv yog muab pov tseg tom qab siv, thiab degraded thiab assimilated nyob rau hauv qhov kev txiav txim ntawm cell biochemistry thiab enzymes ntawm tej yam kab mob xws li kab mob, pwm (fungi) thiab algae los tsim dej, carbon dioxide, methane, thiab lwm yam. Nws dhau los ua PU lossis PVC tawv hluavtaws tawv khoom siv nrog cov pa roj carbon monoxide nyob rau hauv qhov xwm txheej.
B. Qhov tseem ceeb ntawm biodegradable tawv
daws qhov teeb meem loj "cov khib nyiab dawb" tam sim no ib puag ncig muaj kuab paug.Tam sim no, txhua lub teb chaws tau tshaj tawm txoj cai lij choj txwv tsis pub tsim khoom thiab muag khoom ntawm cov ntaub ntawv polymer uas tsis yog degradable xws li cov yas yas.
C. Biodegradablehom
Raws li qhov kawg tshwm sim ntawm degradation: ua tiav biodegradation thiab puas biodegradation.
Ua tiav biodegradable plastics yog tsim los ntawm ntuj polymers los ntawm microbial fermentation los yog synthesis ntawm biodegradable polymers, xws li thermoplastic starch plastics, aliphatic polyester (PHA), polylactic acid (PLA), starch / polyvinyl cawv, thiab lwm yam.
Kev puas tsuaj biodegradable plastics feem ntau suav nrog cov hmoov txhuv nplej siab hloov (lossis ntim) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, thiab lwm yam.
Raws li txoj kev degradation: photodegradable cov ntaub ntawv, biodegradation, yees duab / biodegradation, thiab lwm yam.
D. International mainstream xeem thiab ntawv pov thawj:
USA: ASTM D6400;d5511 ua
Cov European Union: DIN EN13432
Nyiv: Nyiv GREENPLA biodegradable ntawv pov thawj
Australia: AS4736
E. Kev cia siab thiab kev loj hlob:
Tam sim no, vim tias "cov khib nyiab dawb" tau cuam tshuam rau tib neeg lub neej nyob ib puag ncig, feem ntau lub teb chaws hauv ntiaj teb tau txwv tsis pub tsim khoom, muag thiab siv cov khoom tsis-degradable.Yog li ntawd, biodegradable hluavtaws tawv thiab hluavtaws tawv yog qhov tsim nyog kev ua tau zoo ntawm cov tawv nqaij yav tom ntej, thiab nws tseem yog tus qauv tsim nyog rau cov neeg siv khoom.
A. yog dab tsitawv tawv:
Recycled tawv yog hais txog cov khoom siv tawv tawv tiav uas tsim los ntawm kev tsim cov tawv tawv thiab hluavtaws tawv, qee qhov los yog tag nrho cov khoom siv pov tseg, uas tau siv dua thiab rov ua dua tshiab rau hauv cov ntaub los yog tawv tawv.
B. Hom khoom siv tawv tawv:
Tam sim no, cov khoom tseem ceeb ntawm cov tawv nqaij yog tawv tawv thiab hluavtaws tawv uas tsim los ntawm kev siv cov ntaub siv rov ua dua tshiab.
Huaian Kaiyue Technology Development Co., Ltd. siv cov khoom siv rov ua dua tshiab los tsim cov tawv hluavtaws, thiab ntau tus phooj ywg ib puag ncig yog dej-raws li cov tawv hluavtaws tawv.Ua tiav xoom VOC emissions, tsis muaj kuab paug hauv cov txheej txheem tsim khoom, thiab kev tiv thaiv ib puag ncig ntsuab.
C. Lub ntsiab lus ntawm cov tawv tawv:
Txhawm rau tiv thaiv ib puag ncig, kev txuag hluav taws xob thiab txo qis emissions, rov siv dua thiab rov siv cov peev txheej, thiab txhawb kev txhim kho kev lag luam thiab kev sib raug zoo.Ntau thiab ntau lub tuam txhab nto moo thoob ntiaj teb ua si daim npav ntawm "kev tiv thaiv ib puag ncig" thiab tawm tswv yim siv cov ntaub ntawv zoo ib puag ncig, yog li cov khoom siv rov ua dua tshiab tau dhau los ua lawv "cov nyiam".
D. Kev xeem thiab ntawv pov thawj:
GRS (Ntiaj teb no Recycle Standard) - Ntiaj teb no Recycle Standard Certification, Boze tawv muaj nws
E. Cov txiaj ntsig ntawm GRS daim ntawv pov thawj:
1. Kev lees paub thoob ntiaj teb, kom tau txais daim ntawv hla tebchaws rau cov khoom nkag mus rau theem thoob ntiaj teb;
2. Cov khoom yog cov pa roj carbon tsawg thiab ib puag ncig tus phooj ywg, thiab tuaj yeem taug qab;
3. Kev nkag mus rau cov ntaub ntawv khaws cia ntawm lub ntiaj teb nto moo lag luam thiab cov npe thoob ntiaj teb;
4. Ua raws li cov kev cai ua lag luam ntawm "ntsuab" thiab "kev tiv thaiv ib puag ncig", thiab txhim kho cov txheej txheem kev cuam tshuam ntawm cov khoom
5. Txhim kho lub hom phiaj kev paub ntawm lub tuam txhab.
