Cov xov xwm tsis ntev los no hais txog "cov dej-soluble cov ntaub ntawv" tuaj yeem piav qhia qhov khoom tawg. Daim yeeb yaj kiab yas-dej-tiv thaiv cov yeeb yaj kiab tau tso tawm rau ntawm "Lub Tsev Haujlwm Zoo Siab" thaum yav tsaus ntuj Lub Yim Hli 10, uas tsis yog tsuas yog ua rau cov qhua tsis txaus siab xwb, tab sis kuj tseem nqus. Qhov muag ntawm feem ntau ntawm cov neeg tuaj saib. Yog li cov khoom ntxim nyiam no muaj dab tsi? Koj tuaj yeem qhia nws hauv phau ntawv ceev, qhia rau peb paub txog nws.
Nyob rau xyoo tas los no, muaj ntau theem ntawm "cov cua daj cua dub" raug cuam tshuam thoob plaws hauv lub tebchaws. Hauv cov ntsiab lus ntawm Shanghai kev faib tawm cov khib nyiab, lo lus "tiv thaiv ib puag ncig" tau dhau los ua cov ncauj lus tseem ceeb. Hauv qhov teeb meem no ntawm kev nrawm nrawm, nyob rau hauv lub ntsiab lus loj ntawm cov khib nyiab xaiv, ntau cov khoom siv tawm hauv kev tiv thaiv ib puag ncig, suav nrog "dej-soluble film", tau tshwm sim ib txhij. Ntxiv rau kev ua kom pom cov khoom lag luam yas txog kev lag luam uas nws tau tsim, nws kuj tau nqa ib lub hnab yas uas yog soluble hauv dej. Nws tau hais tias lub hnab no tshwm sim rau kev tshem tawm "cov pa phem dawb". Raws li peb txhua tus paub, kev ua qias tuaj yas yog ib qho ntawm cov pa phem teeb meem uas yuav tsum tau daws sai sai thoob ntiaj teb. Qhov laj thawj yog vim li cas cov hnab yas nqa cov kuab paug ib puag ncig tsuas yog vim qhov ua kom qeeb ntawm lub hnab. Ib lub hnab yuav siv sij hawm nruab nrab ntawm 25 feeb, tab sis nws yuav siv sijhawm li 400 xyoo los ua kom zoo kiag li. Qhov "dej-soluble hnab yas" hauv qhov kev zov me nyuam tuaj yeem yaj sai nyob rau hauv thaj chaw muaj dej ntau. Raws li Huang Ningning, cov khoom siv no tuaj yeem yaj tau los ntawm kev tsim cov txheej txheem huab cua sib txawv, thiab cov kua ploj yog tsis muaj tshuaj lom. Nws yog cov tsis ua paug, thiab txawm hais tias lub hnab muab tso rau hauv cov tsiaj qus, nws tuaj yeem ua rau biodegraded yam tsis muaj kev cuam tshuam ib puag ncig.
Tus neeg sau xov xwm tau pom lub hnab hauv ntau cov tsev kho mob loj hauv Guangzhou. Lub hnab tau sau los ntawm kev siv tus kheej lub tshuab muag khoom. Tus neeg sau xov xwm tseem tau txais ib lub hnab raws li kev ua haujlwm. Cov txheej txheem kev sau cia yog qhov yooj yim, tab sis rau cov neeg tsis muaj kev txawj ntse hauv kev siv cov xov tooj ntse, xws li cov neeg laus, cov ntawv sib sau no kuj tsis yooj yim.
Yog li nws yog qhov yooj yim siv xws li hnab dej-soluble thiab hauv ib puag ncig zoo li cas? Tus kws tshaj xov xwm tseem ua ib qhov kev sim. Tus tau ntim-lub peev xwm ntim ntawm lub hnab yog tib yam li qhov ntawm ib lub hnab yas ib txwm. Thaum nws ntws rau qhov dej kub ib txwm, nws yuav ua mos muag. Yog li, kev siv lub hnab yog tib yam ntawm kev siv lub hnab yas. Txawm li cas los xij, yog tias lub hnab ntim tau puas thaum los nag, Cov kev ua tau zoo txaus.
Txhawm rau kom nkag siab ntxiv txog cov khoom siv no, tus kws sau ntawv xov xwm tom qab ntawd mus rau lub tuam txhab tsim thiab tsim cov khoom siv no, Green Dragon Group, thiab muaj kev sib txuas lus sib txuas nrog Yu Zibo, tus thawj tswj hwm ntawm Green Network. Yu Zibo tau hais tias cov khoom siv ntawm cov dej-cov tshuaj tiv thaiv tau siv dav hauv cov teb chaws txawv teb chaws, xws li lub hnab nqa tsiaj tuaj tshwm hauv cov phiaj xwm ceev, tam sim no cov khaub ncaws ntxhua khaub ncaws kub (sab nraud zaj duab xis), hnab ntim tshuaj tua kab thiab kev kho mob lub hnab tiv thaiv kev tiv thaiv tsis zoo.
Muaj ob qho laj thawj rau qhov hnoos qeev ntsuab los thawb lub hnab. Ua ntej, kev tiv thaiv kev lag luam hauv ib cheeb tsam tau pib nkag mus rau hauv lub caij nyoog ntawm kev sib sib zog nqus. Saib ntawm txoj kev txhim kho ntawm kev tiv thaiv ib puag ncig kev lag luam, 2019 yog qhov tsis muaj qhov tseeb ntawm qhov xwm txheej tshiab, thiab cov txheej txheem kev cai ntau ntawm cov dej thiab cov av pov tseg tau tsim. Raws li tus qauv tshiab, kev tiv thaiv ib puag ncig kev lag luam tau nkag mus rau hauv lub sijhawm ntawm txoj cai tswjfwm los ntawm lub sijhawm ntawm kev cog qoob loo. Txij li thaum tso tawm daim ntawv txwv cov yas txwv xyoo 2008, qhov teeb meem ntawm kev tshem tawm cov hnab yas tsis tau daws teeb meem, tab sis kev tswj hwm kev ua qias tuaj yog qhov haujlwm tseem ceeb. Kev txwv txiav dav dav kuj tseem nyob ib ncig ntawm lub ces kaum. Los ntawm qhov pom ntawm qhov loj puag ncig, kev ua lag luam kuj tseem xav tau kev hloov chaw yooj yim rau cov hnab yas zoo tib yam. Cov.
Thib ob, cov neeg paub txog ib puag ncig ntawm kev tiv thaiv ib puag ncig tau nce zuj zus. Nrog kev txhim kho ntawm cov neeg nyob hauv kev ua neej nyob, lawv cov kev paub txog ib puag ncig tau ua tiav tas li. Cov pej xeem lub siab mus rau kev tiv thaiv ib puag ncig tau nce, thiab cov thaj tsam thiab qhov kev koom tes tau maj mam dhau mus. Qhov kev siv tseem ceeb ntawm cov dej ua kua hnab yog vam tias yuav ua kom nrov-dej lom puag ncig cov khoom siv los ntawm cov khoom lag luam uas tib neeg muaj peev xwm them taus, es tsis ua cov khoom lag luam zoo rau qee tus neeg.
Nws raug tshaj tawm tias lub hnab no tsuas yog tsim hauv cov chaw kho mob loj thiab kev noj qab haus huv thiab cov khw muag tshuaj hauv lub nroog Guangdong. Cov kev tshawb nrhiav thiab kev txhim kho ntawm cov dej-cov tshuaj lom neeg tseem nyob rau theem ntxov ntawm kev txhim kho. Nws yog tseem tsim nyog los ua tag nrho cov dag zog los npog thiab siv nws. Txawm hais tias lub hnab dej-soluble tuaj yeem daws cov teeb meem ntawm kev ua qias tuaj dawb xav tau kev tshuaj xyuas mus ntev, tab sis rau tam sim no, txhawb kev siv cov khoom zoo li no tsis muaj tseeb yog ib txoj hauv kev los txo cov pa phem ib puag ncig. Tus neeg sau xov xwm tseem hais tau txhua tus, ntsuab. Taug kev, sim nqa koj lub hnab ntsuab lossis siv hnab ntsuab ua haujlwm ua ke txhawm rau tiv thaiv ib puag ncig.
