Dab tsi yog cov hnab yas degradable?
1. Deplable plastics:
Degradable yas hais txog qhov sib ntxiv ntawm qee qhov muaj nuj nqi ntxiv (xws li cov hmoov txhuv nplej siab, hloov hmoov txhuv nplej siab lossis lwm cov cellulose, photosensitizer, biodegradation tus neeg sawv cev, thiab lwm yam) hauv cov txheej txheem ntau lawm, uas txo nws txoj kev nyob ruaj khov thiab yooj yim dua hauv thaj chaw ib puag ncig. yas.
2. Kev faib tawm:
Deplable plastics feem ntau muab faib ua plaub pawg:
1. Photodegradable yas
Teeb cov kab mob photosensitizer hauv plastics kom maj mam decompose plastics hauv qab lub hnub ci. Nws yog los ntawm kev tsim ua ntej ntawm cov yas degradable, thiab nws qhov tsis zoo yog lub sijhawm degradation nyuaj rau kev twv ua ntej vim hnub ci thiab huab cua hloov, yog li lub sijhawm hloov kho tsis tuaj yeem tswj tau.
2. Cov roj hmab biodegradable
Raws li qhov kev ua ntawm cov kab mob me me, nws tuaj yeem ua tiav rau hauv cov yas uas tsis muaj molecular compound. Nws yog tus cwj pwm los ntawm kev yooj yim khaws cia thiab kev thauj mus los, ntev li ntev tau khaws cia qhuav thiab tsis tas yuav muaj kev tiv thaiv los ntawm lub teeb, thiab muaj ntau ntawm cov ntawv thov. Nws tuaj yeem siv tsis tsuas yog ua liaj ua teb mulch, ntim hnab, tab sis kuj siv hauv thaj chaw kho mob. Nrog rau kev nthuav dav ntawm biotechnology niaj hnub, biodegradable plastics tau txais ntau dua thiab ntau dua, thiab tau dhau los ua cov cim tshiab ntawm kev tshawb nrhiav thiab kev txhim kho hotspots.
3. Lub teeb / biodegradable yas
Ib hom yas uas sib txuas ntawm photodegradation thiab microorganisms. Nws muaj cov yam ntxwv ntawm ob leeg photodegradation thiab microbial kev puas tsuaj ntawm cov yas.
4. Dej tsis zoo yas
Txuas ntxiv dej-nqus tshuaj mus rau cov yas thiab yaj lawv hauv dej tom qab siv. Nws yog feem ntau siv rau hauv cov khoom siv kho mob thiab huv (xws li hnab looj tes kho mob) rau kev rhuav tshem yooj yim thiab tshuaj tua kab mob.
3. Taw qhia:
Kev ntsuam xyuas pom tau tias feem ntau ntawm cov yas uas ua rau lub cev pib yuag, poob phaus, poob lub zog tom qab tau cuam tshuam rau ib puag ncig puag ncig rau 3 lub hlis, thiab maj mam tawg mus ua tej daim. Yog tias cov thooj no tawg ua ke rau hauv cov khib nyiab lossis av, qhov cuam tshuam tsis zoo yog qhov tsis pom tseeb.
Cov ntaub ntawv txuas ntxiv
GG quot muaj teeb meem dab tsi; degradable plastics" coj?
Tsis hais txog ntawm cov khoom siv nws tus kheej, tam sim no tsis muaj cov kev lag luam cog qoob loo thoob plaws Suav teb, thiab cov khib nyiab sib cais thiab rov ua dua qub tsis ua haujlwm zoo.
Txhawb nqa kev siv" degradable plastics" yuav tuaj yeem coj&tshiab quot; kev ua qias tuaj dawb" ;. Thiab kev tshaj tawm ntawm" degradable plastics" yuav yooj yim ua rau cov pej xeem xav tias qhov no yog cov khoom uas" tuaj yeem ploj mus yam tsis muaj kev kho" thiab ua rau muaj kev dag ntxias.
Rov qab mus rau qhov teeb meem tseem ceeb tshaj plaws, kev ua qias tuaj yas tam sim no ntsib Suav teb thiab lub ntiaj teb yog tus nqi ntawm kev noj ntau dhau thiab kev lav phib xaub tsis lav. Txawm hais tias" degradable plastics" tuaj yeem hloov mus rau hauv cov nplooj lwg ua lag luam kom daws cov teeb meem kev ua qias, kev noj ntawm" degradable plawg" thaum kawg tau noj cov khoom siv ib puag ncig. Los ntawm qhov kev pom no, qhov peb yuav tsum xav txog yog yuav ua li cas thiaj txo cov teeb meem ntawm qhov chaw noj ntau dhau.
Tab sis peb tsis tuaj yeem tsis lees paub tias yav tom ntej, degradable plastics yuav yog qhov hloov kev txhim kho. Deng Xiaogang, tus thawj coj ntawm Hainan Ceg Saib Xyuas Ib Cheeb Tsam ntawm Ecology thiab Ib puag ncig, hais tias,
GG quot; Tam sim no tsis muaj lub teb chaws tus qauv rau tag nrho cov khoom lag luam biodegradable, thiab tsis muaj cov qauv tseem ceeb hauv lwm cov xeev, yog li Hainan xav tawm tswv yim thiab yog thawj hauv biodegradable hauv zos cov qauv." Qhov no tseem muaj nws qhov tseem ceeb.
Tom ntej no, Kuv cia siab tias qhov kev pib ntawm Hainan no yuav yuam kom txhim kho thiab txhim kho ntawm kev sib tsuam yas technology thiab rhuav cov teeb meem ntawm thev naus laus zis, cov qauv, kev tsim khoom, cov txheej txheem khiav lag luam, thiab lwm yam rau kev txhawb nqa ntawm cov yas uas tsis zoo nyob rau yav tom ntej, kom nws tuaj yeem tswj hwm" dawb"" Kuab paug" tau dhau los ua qhov kev ua tau zoo tiag tiag thiab zoo tshaj plaws kev daws teeb meem.
