Xyoo no ob lub rooj sib tham tau muaj nyob rau hauv Great Hall of the People hauv Beijing thaum Lub Peb Hlis 5, 2021, thiab carbon peaking thiab carbon neutrality tau sau rau hauv tsoomfwv daim ntawv tshaj tawm ua haujlwm thawj zaug! Thawj Tswj Hwm Li Keqiang tau taw qhia nyob rau hauv 2021 Lub Xeev Pawg Neeg Saib Xyuas Kev Ua Haujlwm Tshaj Tawm tias tsoomfwv yuav tsum ua txoj haujlwm ruaj khov ntawm kev ua tiav cov pa roj carbon ntau thiab cov pa roj carbon monoxide, tsim cov phiaj xwm ua kom ua tiav cov pa roj carbon ntau tshaj plaws los ntawm 2030, thiab txhim kho cov qauv kev lag luam thiab lub zog. Ob lub tswv yim no yog hluav taws kub, yog li maj nrawm thiab nrhiav seb qhov twg yog qhov txhais tau tias yog carbon peaking thiab carbon neutrality!
Cov pa roj carbon nruab nrab txhais tau hais tias cov tuam txhab, pab pawg lossis cov tib neeg ntsuas tag nrho cov pa hluav taws xob hauv tsev cog khoom uas tsim tawm ncaj qha lossis tsis ncaj rau hauv ib lub sijhawm, thiab cuam tshuam lawv tus kheej cov pa roj carbon dioxide emissions los ntawm kev cog ntoo, txuag lub zog thiab txo cov emissions, thiaj li ua tiav " zero emission" ntawm carbon dioxide. Lub "carbon ncov" yog hais txog Tuam Tshoj txoj kev mob siab rau kom tsis txhob muaj kev loj hlob ntawm carbon dioxide emissions los ntawm 2030, thiab maj mam txo lawv tom qab mus txog lub ncov.
Cov pa roj carbon "hauv cov ntsiab lus ntawm carbon neutrality thiab carbon peaking tiag tiag yog hais txog cov pa roj carbon dioxide, tshwj xeeb tshaj yog cov pa roj carbon dioxide tsim los ntawm tib neeg kev tsim khoom thiab kev ua neej nyob. Ntxiv nrog rau qhov nce ntawm cov pa roj carbon dioxide, cov ncej kuj tau pib ua kom nrawm ntawm cov dej khov yaj raws li kev txheeb cais, cov dej khov hauv Greenland tuaj yeem yaj 2 billion tons hauv ib hnub Cov roj methane ntau npaum li cas nyob rau hauv permafrost, thiab thaum lub permafrost melts, nws yuav aggravate lub tsev cog khoom nyhuv yog li ntawd, nws yuav tsum tau kev sib koom tes ntawm tag nrho cov teb chaws.
Tuam Tshoj tau ua tiav cov txiaj ntsig tau zoo, nrog rau Tuam Tshoj cov pa roj carbon emissions zog poob los ntawm 48.1% hauv 2019 piv rau 2005, ua ntej 2015 lub hom phiaj ntawm 40% mus rau 45% txo; Txij li thaum lub 18th Party Congress, Tuam Tshoj txoj kev sib koom ntawm lub zog huv hauv tag nrho cov kev siv hluav taws xob tau mus txog 23.4%, nrog rau cov khoom tsim muaj peev xwm ntawm hydropower, cua zog thiab hnub ci zog tag nrho cov qib siab hauv ntiaj teb.
Txawm hais tias cov pa roj carbon dioxide ua rau lub ntiaj teb lub tsev cog khoom muaj txiaj ntsig, tsis tas yuav tham txog "carbon", nws yog ntau tshaj ntawm cov pa roj carbon dioxide uas ua rau txhua yam teeb meem tsis zoo, thiab cov pa roj carbon dioxide tsis zoo tag nrho. Peb txhua tus paub tias cov nroj tsuag xav tau cov pa roj carbon dioxide rau photosynthesis, thiab hauv kev ua liaj ua teb, qee cov pa roj carbon dioxide tuaj yeem muab ntxiv kom cov qoob loo nce ntxiv; nws yog siv los ua cov pa oxygen hauv kev dhia dej thiab aviation; nws feem ntau yog siv los ua hluav taws tua hluav taws; thiab nws yog ib qho tseem ceeb ntawm cov khoom siv raw. Nws yog siv los tsim cov dej qab zib ntau ntau, ci dej qab zib, urea, thiab lwm yam, thiab hauv kev lag luam teeb pom kev zoo los tsim cov dej qab zib, npias, dej qab zib, thiab lwm yam.; nws kuj tseem tuaj yeem ua rau cov dej khov qhuav qhuav, xws li cov dej nag, thiab lwm yam. Nws tuaj yeem hais tau tias nws yog ib qho tseem ceeb roj hauv tib neeg kev tsim khoom txhua hnub, thiab kev siv tus nqi siab heev. Txawm li cas los xij, hauv kev tsim khoom, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov tseeb tias cov pa roj carbon dioxide concentration siab dhau lawm, uas yuav ua rau kom cov concentration ntawm carbonic acid hauv tib neeg cov ntshav, txhim kho acidity thiab tsim acidosis. Thaum lub ntim feem ntawm cov pa roj carbon dioxide nyob rau hauv cov huab cua yog 1%, cov neeg xav tias khaus, kiv taub hau thiab palpitating; thaum nws yog 4% -5%, lawv xav tias kiv taub hau; thaum nws yog 6% lossis ntau dua, tib neeg ua tsis meej pem thiab ua pa maj mam nres, uas ua rau tuag. Yog li ntawd, nyob rau hauv qee cov nroj tsuag tshuaj, breweries, tsev cog khoom, ua liaj ua teb thiab lwm qhov chaw, nws yog qhov zoo dua rau nruab cov pa roj carbon dioxide sensors kom pom qhov concentration ntawm carbon dioxide kom tsis txhob muaj xwm txheej txaus ntshai.
HENGKO CO2 sensormuaj rhiab heev, ruaj khov thiab ntsuas qhov tseeb: lub ntiaj teb (40ppm + 3% FS) (25 ° C); lub sij hawm teb ceev ceev. Nws muaj qhov taw qhia LED nyob rau pem hauv ntej los qhia txog lub tswb tam sim no. Txais cov pob qhov rooj zeroing thiab calibration knob los kho lub ntes, uas yog yooj yim rau cov neeg siv los kho tus ntes ncaj qha rau ntawm qhov chaw, thiab tuaj yeem muab cov qauv 4-20mA tam sim no.
HENGKO gas sensor tawg-pov thawj vaj tsevmuaj nyob rau hauv ntau hom qauv nrog kub tsis kam, corrosion kuj, plua plav pov thawj, tawg-pov thawj, nplaim hluav taws kev ua tau zoo, thiab peb cov khoom muaj siab permeability thiab siab filtration raug rau cov roj nrhiav tau nyob rau hauv ib puag ncig ntawm -70 ° C mus rau 600 ° C. , 150 Pa siab tsis kam, thiab pore loj li ntawm 0.2μm - 90μm yeem. Lwm cov nickel-raws li alloys tuaj yeem kho tau yog tias koj daim ntawv thov yuav tsum muaj kev tiv thaiv corrosion, kub, abrasion thiab vibration.
