Cov kev daws teeb meem zoo tshaj plaws rau ib puag ncig kev cuam tshuam ntawm cov khoom siv yas pov tseg --- Reverte
Peb txhua tus paub tias cov khoom lag luam yas, tshwj xeeb tshaj tawm cov khoom lag luam yas, tau tsim kev kub ntxhov rau peb ib puag ncig. Lub ntiaj teb tag nrho tab tom nrhiav ib txoj hauv kev zoo thiab siv tau los daws cov teeb meem tshwm sim los ntawm cov khoom siv yas pov tseg mus rau lub ntiaj teb.
Hauv cov ntsiab lus teb no, peb qhia Reverte, uas yog high-tech environmentally friendly degradable masterbatch tsim nyob rau hauv UK, uas tuaj yeem hais tau tias yog cov tshuaj zoo tshaj plaws rau cov khoom pov tseg yas.
Cov khoom siv yas pov tseg uas peb siv tam sim no tuaj yeem ua rau degraded. Nws yuav siv sijhawm ntev heev txheej txheem-ntev 100 mus txog 200 xyoo. Qhov no yog vim tias cov yas tau ua los ntawm polyethylene. Nyob ntawm cov mob polymerization, polyethylene tus txheeb ze molecular hnyav muaj los ntawm 10,000 txog ntau lab. Xws li lub cev hnyav molecular yog qhov nyuaj rau degrade hauv xwm hauv lub sijhawm luv luv.
Thiab Reverte ntxiv los ntawm Norrish tshuaj lom neeg cov tshuaj tiv thaiv uas los ntawm kev sib tiv tauj ntawm qee yam tshwj xeeb hlau ions raws li cov txheej txheem ua ntej, cov phaus molecular ntawm cov khoom yas tuaj yeem raug txo sai rau 10000 lossis tseem qis dua 5000 hauv lub sijhawm luv luv, kom cov khoom lag luam yas tuaj yeem pov tseg tom qab siv. Nws tau noj sai sai thiab yaig los ntawm cov kab mob. Hauv lwm lo lus, nws tuaj yeem nrawm nrawm los ntawm xwm, ib yam li nplooj, tev pov tseg
nyob rau hauv cov xwm thiab sai sai decomposed by kab mob.
Lub luag haujlwm ntawm Reverte tau muab faib ua ob ntu. Thawj qhov yog tias tom qab cov khoom siv yas pov tseg siv, nws hla lub teeb thiab oxidation, thiab Norrish tshuaj lom neeg pib hauv 48 teev, thiab lub cev hnyav molecular txo; qhov thib ob yog thaum lub cev hnyav molecular txo mus rau 10,000 lossis txawm qis dua 5,000. , Tsuas yog zoo li organic teeb meem nyob rau hauv cov xwm, nws yuav tau noj los ntawm microorganism ds thiab yaig sai sai. Thiab nws kuj muaj tus qauv siv rau cov neeg nyiam nyiam. Thaum cov khoom siv yas pov tseg no tau muab ntim rau hauv ib lub thawv thiab tsis siv, lawv yuav tsis thim tawm, thiab lawv kev ua tau zoo tuaj yeem khaws cia rau 2 xyoos.
Tom qab ntawd yuav ua li cas siv Reverte? Tsuas yog muab tso rau hauv 1% rov qab masterbatch rau hauv cov thawv sib tov thaum tsim cov zaj duab xis yas, koj zaj duab xis yas yuav biodegradable.
Tam sim no, ntau lub lag luam xaiv cov hmoov txhuv nplej siab raws li khoom lag luam PLA kom ua tiav cov nyhuv xeb. Cia peb luv luvtxheeb xyuas qhov zoo thiab qhov tsis zoo ntawm peb Reverte thiab PLA.
Ua ntej: Ntxiv rau Reverte rau hauv cov yas pov tseg tuaj yeem ua rau nws ncaj qha los ntawm kev puas tsuaj, txawm tias nws yog ncaj qha muab pov tseg, nws yuav tsis ua rau cov teeb meem ib puag ncig.
Tam sim no, feem ntau ntawm cov khoom lag luam yas PLA yog tsim los ntawm PLA cov khoom sib xyaw nrog cov hnab yas PE. Lub PLA yuav tsum yogmuaj qee qhov nyob hauv cov nplooj lwg, thiab cov PE cov khoom yuav tsis ua paug. Nplooj lwg yog heevmuaj kev nyuaj. Nws tsis yog nws tsuas yog los ntawm kev faus rau hauv av. Qhov tseeb, muaj ob lub ntsiab. Ua ntej, nplooj lwgcov chaw kho mob, uas hais txog cov chaw nres khib nyug lossis cov khib nyiab ntim chiv; thib ob, cov xwm txheej tsim nyog, qhov no hais txog ntawmlub cev muaj pes tsawg leeg ntawm kev zom zaws, uas yuav tsum muaj cov khib nyiab organic thiab cov kab mob me me, thiab tsuas yog ua tiav hauv qab tej qhov kub thiab txias, av noo thiab microorganism tej yam kev mob. Ob lub ntsiab lus no txiav txim siab qhov nyuaj ntawmcov nplooj lwg. Peb tsis muaj chaw lim dej. Peb yuav tsum tau yuav lawv. Peb yuav tsum xaiv tawm lub inorganicteeb meem hauv lub thoob khib nyiab kom tsis txhob tov rau hauv cov khoom ntim tau yooj yim, vim tias cov teeb meem tsis muaj ntxeem tau yuav muab xyaw tau.
Thib Ob: Cov khoom kawg ntawm kev ua kom tsis zoo los ntawm kev siv Reverte yog carbon dioxide thiab dej. Nws yog txiaj ntsig ntawm kev zom zaub movlos ntawm cov kab mob me me.
Kev siv PLA nplooj lwg yuav ua kom kub thiab biogas (methane). Raws li peb txhua tus paub, methane yog qhov tseem ceebtsev cog khoom roj.
Thib peb: Reverte tsis nyob cov khoom noj muaj txiaj ntsig.
Kev siv cov khoom lag luam ntawm PLA ua rau cov khoom noj hloov tiag tiag (feem ntau ntawm PLA cov khoom nyoos tuaj ntawm pob kws ua kom rho tawm) mus rau hauv cov khoom siv pov tseg. Nrog rau qhov tsis txaus txuas ntxiv ntawm cov zaub mov thoob ntiaj teb, cov neeg tshaib plab ntxiv musnce, thiab cov kev coj cwj pwm uas nkim cov zaub mov yuav ntsib ntau yam teeb meem thiab kev pheej hmoo.
Plaub: siv Reverte yog nyiaj txiag ntau dua li PLA.
Thib tsib: Cov khoom kawg ntawm kev ua tsis zoo ntawm kev siv Reverte tuaj yeem siv rov qab ua ntej cov phaus molecular tsis tau poob rau 10,000, lawv tseem tuaj yeem dhau los ua cov yas zoo tib yam sib xyaw nrog lwm cov yas thiab rov siv dua.
Tam sim no tsis muaj qhov kawg xaus ntawm seb PLA tuaj yeem rov qab ua dua tshiab thiab rov ua dua tshiab rau kev granulation.
