Yog vim li cas rau qhov kev nce qib qeeb ntawm cov hnab yas degradable tag nrho

1. Kev tshawb fawb txog kev siv tshuab yas degradable hauv Suav teb tau pib ntxov, thiab muaj ntau yam khoom siv hnab yas degradable tag nrho, suav nrog cov ntses hauv dej muaj teeb meem thiab cov neeg dag. Kev lag luam ib puag ncig yog complex, thiab cov khoom zoo tsis sib xws. Yog li ntawd, ntau tus neeg siv khoom yog qhov nyuaj rau kev paub qhov txawv, thiab muaj ntau tus neeg dag ntxias. Nws tuaj yeem hais tau tias nyob rau xyoo thaum ntxov, cov tub lag luam uas tsis zoo siv los pov pob zeb ntawm lawv ko taw, cuam tshuam rau lub khw muag khoom zoo thiab ua rau cov neeg siv khoom ntshai raug nab tom rau kaum xyoo.
2. Cov neeg siv khoom paub txog kev tiv thaiv ib puag ncig tsis txaus. Nyob rau hauv xyoo tas los no, ib puag ncig muaj kuab paug tau dhau los ua qhov tseem ceeb, thiab lo lus "kev tiv thaiv ib puag ncig" tau dhau los ua lub ntsiab lus kub. Cov pej xeem paub txog kev tiv thaiv ib puag ncig kuj tau nce ntxiv, tab sis kev paub txog kev tiv thaiv ib puag ncig tsis muaj zog txaus. Cov hnab yas degraded lawv tus kheej muaj cov yam ntxwv ib puag ncig, uas nyuaj rau kev kuaj xyuas. Cov neeg feem coob ntseeg tias kev them nyiaj rau kev tiv thaiv ib puag ncig yuav tsis ua rau cov txiaj ntsig luv luv thiab tsis xav txog cov txiaj ntsig ntev. Yog li ntawd, nyob rau hauv lawv ob lub qhov muag, lawv siv lub hauv paus ntawm tus nqi ntawm cov hnab yas zoo tib yam los ntsuas cov khoom hloov nrog ib puag ncig cov yam ntxwv, thiab yog li tsis paub txog hom kev noj no.
3. Tus nqi ntawm cov tshuab degradation yog siab, thiab kev degradation ntawm cov yas yeej ib txwm yog ib qho kev sib tw loj rau kev tshawb fawb hauv zej zog. Tam sim no, muaj ob lub ntsiab degradation technologies nyob rau hauv kev ua lag luam. Ib qho yog siv degradation masterbatches kom ua tiav cov txheej txheem degradation ntawm polyethylene nyob rau hauv ib puag ncig ntuj, thiab lwm yam yog hloov cov tshuaj ethylene substrates nrog tag nrho cov ntaub ntawv lom. Ob txoj kev thev naus laus zis no yog ob qho tib si hauv kev ua lag luam, thiab qhov teeb meem tseem ceeb tam sim no yog tus nqi ntawm kev siv, vim tias tus nqi ntawm cov khoom tsis zoo ntawm ob qho tib si thev naus laus zis yuav yog ob npaug ntawm cov khoom siv tib yam, ua rau kev lag luam tsis tshua muaj neeg nyiam.
