Imihlangano emibili yalo nyaka ibanjelwe eHholo Elikhulu Labantu eBeijing ngoMashi 5, 2021, futhi ukwehla kwekhabhoni kanye nokungathathi hlangothi kwekhabhoni kwabhalwa embikweni womsebenzi kahulumeni okokuqala! UNdunankulu uLi Keqiang waveza embikweni woMsebenzi kaHulumeni woMkhandlu Wesifundazwe ka-2021 ukuthi uhulumeni kufanele enze umsebenzi oqinile wokufeza ukungathathi hlangothi kwekhabhoni kanye nekhabhoni, akhe uhlelo lokusebenza lokufeza ukukhishwa kwekhabhoni okuphezulu ngo-2030, futhi enze ngcono isakhiwo sezimboni kanye nesakhiwo samandla. Le mibono emibili iyasha, ngakho shesha uthole ukuthi kusho ukuthini ukwehla kwekhabhoni kanye nokungathathi hlangothi kwekhabhoni!
Ukungathathi hlangothi kwekhabhoni kusho ukuthi amabhizinisi, amaqembu noma abantu ngabanye balinganisa inani eliphelele lokukhishwa kwegesi ebamba ukushisa okukhiqizwa ngqo noma ngokungaqondile phakathi nesikhathi esithile, futhi banciphise ukukhishwa kwegesi ebanga ukushisa ngokutshala izihlahla, bonge amandla futhi banciphise ukukhishwa kwegesi, ukuze kufezwe "ukukhishwa kwegesi ebanga ukushisa" kwekhabhoni ebanga ukushisa. "I-carbon peak" ibhekisela ekuzibophezeleni kweShayina kokulwela ukumisa ukukhula kokukhishwa kwegesi ebanga ukushisa ngo-2030, futhi kunciphise kancane kancane ngemva kokufinyelela esicongweni.
I-Carbon" emiqondweni yokungathathi hlangothi kwekhabhoni kanye nokuphakama kwekhabhoni empeleni ibhekisela ku-carbon dioxide, ikakhulukazi i-carbon dioxide ekhiqizwa ukukhiqizwa kwabantu kanye nemisebenzi yokuphila. Sonke siyazi ukuthi eminyakeni yamuva nje, umphumela wokushisa komhlaba wonke ubangele izinkinga ezahlukahlukene zomonakalo wemvelo, futhi ngaphezu kokwanda kokukhishwa kwekhabhoni dioxide, izigxobo nazo ziqale ukusheshisa izinga lokuncibilika kweqhwa. Ngokwezibalo, iqhwa eGreenland lingancibilikisa amathani ayizigidi eziyizinkulungwane ezimbili ngosuku. Ngaphezu kwalokho, kunegesi enkulu ye-methane ngaphansi kwe-permafrost, futhi uma i-permafrost incibilika, kuzokwandisa umphumela wokushisa. Ngakho-ke, kudinga imizamo ehlangene yawo wonke amazwe.
I-China yenze impumelelo emangalisayo, njengoba ukukhishwa kwekhabhoni e-China kwehla ngo-48.1% ngo-2019 uma kuqhathaniswa no-2005, ngaphambi komgomo ka-2015 wokunciphisa ngo-40% kuya ku-45%; kusukela eNgqungqutheleni Yeqembu Le-18, isabelo se-China samandla ahlanzekile ekusetshenzisweni kwamandla okuphelele sifinyelele ku-23.4%, kanti amandla ahlanganisiwe kagesi wamanzi, amandla omoya kanye namandla elanga konke kuphezulu emhlabeni.
Nakuba i-carbon dioxide inegalelo emphumela wokushisa komhlaba wonke, asikho isidingo sokukhuluma "nge-carbon", ukwanda kwe-carbon dioxide okubangela zonke izinhlobo zezinkinga ezimbi, futhi i-carbon dioxide ayimbi ngokuphelele. Sonke siyazi ukuthi izitshalo zidinga i-carbon dioxide ukuze kwenziwe i-photosynthesis, futhi kwezolimo, i-carbon dioxide ethile ingangezwa ukwandisa isivuno sezitshalo; isetshenziswa njengomthombo we-oxygen ekucwileni nasekuhambeni ngezindiza; ivame ukusetshenziswa njengesicishamlilo; futhi iyinto ebalulekile yokusetshenziswa kwezimboni. Isetshenziselwa ukukhiqiza inani elikhulu lomlotha wesoda, i-baking soda, i-urea, njll., kanye nasembonini elula ukukhiqiza iziphuzo ezine-carbonated, ubhiya, iziphuzo ezithambile, njll.; ingenza futhi i-dry ice agent, njengemvula yokwenziwa, njll. Kungashiwo ukuthi iyigesi ebalulekile ekukhiqizweni kwabantu kwansuku zonke, futhi inani lokusetshenziswa liphezulu kakhulu. Kodwa-ke, ekukhiqizweni, kubalulekile ukunaka iqiniso lokuthi ukugcwala kwegesi ye-carbon dioxide kuphezulu kakhulu, okuzokhulisa ukugcwala kwe-carbonic acid egazini lomuntu, kuthuthukise i-acidity futhi kukhiqize i-acidosis. Uma ingxenye yomthamo we-carbon dioxide emoyeni ingu-1%, abantu bazizwa bexinekile, benesiyezi futhi beshaya ngamandla; uma ingu-4%-5%, bazizwa benesiyezi; uma ingu-6% noma ngaphezulu, abantu bayadideka futhi ukuphefumula kwabo kuyeke kancane kancane, okuholela ekufeni. Ngakho-ke, kwezinye izitshalo zamakhemikhali, ezindaweni zokuphuza utshwala, ezindaweni zokugcina izithombo, emapulazini nakwezinye izindawo, kungcono ukufaka izinzwa ze-carbon dioxide ukuze kutholakale ukugcwala kwe-carbon dioxide ukuze kugwenywe izingozi eziyingozi.
Inzwa ye-HENGKO CO2inozwela oluphezulu, ukusebenza okuzinzile kanye nokunemba kokulinganisa: umhlaba (40ppm+ 3%FS) (25°C); isikhathi sokuphendula okusheshayo. Kukhona inkomba ye-LED ngaphambili ukukhombisa isimo se-alamu yamanje. Sebenzisa inkinobho yokulinganisa engu-zero kanye nenkinobho yokulinganisa ukulungisa i-detector, okulula kubasebenzisi ukulungisa i-detector ngqo endaweni, futhi inganikeza umphumela wamanje ojwayelekile ongu-4-20mA.
Indlu engangenwa ukuqhuma yenzwa yegesi ye-HENGKOitholakala kumamodeli ahlukahlukene anokumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana nothuli, ukumelana nokuqhuma, ukusebenza kokwahlukaniswa komlilo, futhi imikhiqizo yethu inokungena okuphezulu kanye nokunemba okuphezulu kokuhlunga ukuthola igesi ezindaweni ezisukela ku--70°C kuya ku-600°C, ukumelana nokucindezela okungu-150 Pa, kanye nosayizi wembobo osukela ku-0.2μm - 90μm ngokuzithandela. Amanye ama-alloy asekelwe ku-nickel angenziwa ngokwezifiso uma uhlelo lwakho lokusebenza ludinga ukumelana okuphezulu nokugqwala, izinga lokushisa, ukuguguleka kanye nokudlidliza.
Isikhathi sokuthunyelwe: Mashi-27-2021
