Inkomoko: Amakuru y’inganda mu Bushinwa
Ku ya 23 Ugushyingo, urubuga rwemewe rwa Minisiteri y’ibidukikije n’ibidukikije rwasohoye “Urutonde rusabwa rw’abasimbura Hydrochlorofluorocarbon mu Bushinwa (Umushinga w’ibitekerezo)” (aha ni ukuvuga “Urutonde”), rusaba monochlorodifluoromethane (HCFC -22), 1 . , pentane, amazi, hexafluorobutene, trifluoropropene, tetrafluoropropene, nibindi.
Umuntu bireba ushinzwe minisiteri y’ibidukikije n’ibidukikije yavuze ko kuri ubu hari ubwoko bubiri bw’ingenzi bwa HCFCs ubundi bumwe: bumwe ni hydrofluorocarbone (HFCs) ifite ubushyuhe bukabije bw’isi (GWP), bukoreshwa cyane mu bihugu byateye imbere mu myaka myinshi ishize. , kandi bageze no ku musaruro munini mu Bushinwa.inganda nini.Iya kabiri ni GWP isimbuye agaciro, harimo amazi asanzwe akora, fluor irimo olefine (HFO) nibindi bintu.Mu rwego rwo guteza imbere icyiciro cya kabiri cya HCFC, guhuriza hamwe ibyavuye mu cyiciro cya kabiri no gusimbuza HCFC, no kuyobora inganda n’inganda bireba guhanga udushya, guteza imbere no gukoresha ubundi buryo bw’icyatsi na karuboni nkeya, Minisiteri y’ibidukikije n’ibidukikije. , hashingiwe ku ncamake ibyavuye mu cyiciro cya kabiri cya HCFC mu myaka icumi ishize, Ikoreshwa rya hydrocarbone (HCFCs) mu nganda zinyuranye, urebye ibintu nko gukura, kuboneka, n'ingaruka zo gusimbuza ubundi buryo, ubushakashatsi kandi bwateguwe "Urutonde rusabwa rw'abasimbura ba HCFC mu Bushinwa" (aha ni ukuvuga "Urutonde"))."Urutonde" rusaba ubundi buryo bwikoranabuhanga hamwe nubundi buryo bwamenyekanye n’inganda kandi bugashyigikirwa n’imikoreshereze myiza yo mu rugo cyangwa imishinga yo kwerekana, mu gihe dushishikarizwa guhanga udushya no guteza imbere ubundi buryo buke bwa GWP.
Meng Qingjun, umunyamabanga mukuru wungirije w’ishyirahamwe ry’inganda zitunganya plastike mu Bushinwa, mu kiganiro yagiranye n’umunyamakuru w’inganda z’inganda z’Ubushinwa yavuze ko “Urutonde” rusaba ko dioxyde de carbone yakoreshwa mu mwanya wa HCFCs nk’umukozi wifuro wa polystirene ifata ifuro na polyurethane. spray ifuro, itangiza ibidukikije nubukungu, kandi izerekana ibyifuzo byiza.Mu ntambwe ikurikiraho, iryo shyirahamwe rizafatanya cyane na Minisiteri y’ibidukikije n’ibidukikije mu rwego rwo gushimangira iterambere ry’ibindi bikoresho bifata ifuro kugira ngo imikorere ya polyurethane na polystirene ikomeze.
Xiang Minghua, umuyobozi mukuru wa Shaoxing Huachuang Polyurethane Co., Ltd., yavuze ko gusimbuza HCFCs na karuboni ya dioxyde de carbone nkumukozi wifuro wa polyurethane spray ifuro byashyizwe ku rutonde muri “Urutonde”, bizazana amahirwe mashya y’iterambere muri sosiyete.Isosiyete izongera iterambere rya tekinoroji ya karuboni ya dioxyde de carbone hamwe nibikoresho kugirango itange inganda ibisubizo byizewe, bitangiza ibidukikije, kandi bidahenze.
Sun Yu, umuyobozi wa Jiangsu Meside Chemical Co., Ltd., yavuze ko “Igitabo cy’imyaka 14 y’iterambere ry’inganda mu bucuruzi bw’inganda za Polyurethane mu Bushinwa” gisaba ko inganda za polyurethane zigomba kongera iterambere n’ikoreshwa ry’ikoranabuhanga rikoreshwa mu mikorere, icyatsi, umutekano ndetse na ibidukikije byangiza ibidukikije.Guteza imbere cyane gusimbuza agent ifuro ODS.Nka shami rikomeye rishinzwe guteza imbere no gukoresha ikoreshwa rya tekinoroji ya polyurethane mu Bushinwa, Meside ifasha kumenya gusimbuza imiti mito mito ya GWP binyuze mu guhanga udushya no kuzamura ibibyimba bya polyurethane (stabilisateur ifuro) hamwe na catalizator, no guteza imbere hasi -karubone no kurengera ibidukikije mu nganda.
Kugeza ubu, igihugu cyanjye kirimo gukora icyiciro cya hydrochlorofluorocarbone (HCFCs) hakurikijwe ibisabwa na protocole.Nkurikije imyanzuro y’amasezerano ya 19 y’inama y’amashyaka, igihugu cyanjye gikeneye guhagarika umusaruro n’imikoreshereze ya HCFCs ku rwego rw’ibanze mu 2013, kandi bikagabanya urwego rw’ibanze ku 10%, 35% na 67.5% muri 2015, 2020, 2025 na 2030.% na 97.5%, na 2,5% byurwego rwibanze amaherezo yabitswe kugirango abungabunge.Ariko, igihugu cyanjye ntikiratanga urutonde rusabwa rwabasimbura HCFC.Mu gihe kurandura HCFCs bigeze mu bihe bikomeye, inganda n’uturere dutandukanye dukeneye byihutirwa ubuyobozi ku basimbuye kugira ngo inganda n’igihugu bikomeze.
