Ngokwemininingwane yakamuva yezimpahla, ukuhwebelana kwe-China kwe-dichloromethane (DCM) ne-trichloromethane (TCM) ngoFebhuwari 2025 kanye nezinyanga ezimbili zokuqala zonyaka zembule izitayela ezingafani, ezibonisa ukushintshashintsha kwesidingo somhlaba kanye namandla okukhiqiza asekhaya.
I-Dichloromethane: Ithekelisa Ukukhula KweDrayivu
NgoFebhuwari 2025, iChina yangenisa amathani angu-9.3 e-dichloromethane, okuphawula ukwanda okumangalisayo konyaka ngo-194.2%. Kodwa-ke, ukuqoqwa kokungeniswa kwamanye amazwe kwangoJanuwari-Februwari 2025 kufinyelele amathani angama-24.0, kwehle ngo-64.3% uma kuqhathaniswa nesikhathi esifanayo ngo-2024.
Ukuthunyelwa kwamanye amazwe kuxoxe indaba ehlukile. NgoFebhuwari wabona amathani ayi-16,793.1 e-DCM athunyelwa kwamanye amazwe, ukwanda okungama-74.9% unyaka nonyaka, kuyilapho ukuthunyelwa kwempahla kwamanye amazwe okunqwabelanayo kwezinyanga ezimbili zokuqala kufinyelele kumathani angama-31,716.3, kwenyuke ngama-34.0%. ISouth Korea yavela njengendawo ehamba phambili ngoFebhuwari, ingenisa amathani ayi-3,131.9 (18.6% wesamba esithengisiwe), ilandelwa yiTurkey (1,675.9 tons, 10.0%) kanye ne-Indonesia (1,658.3 tons, 9.9%). NgoJanuwari-February, iSouth Korea igcine ukuhola ngamathani angu-3,191.9 (10.1%), kwathi iNigeria (2,672.7 tons, 8.4%) kanye ne-Indonesia (2,642.3 tons, 8.3%) inyukele phezulu.
Ukwenyuka okubukhali kokuthunyelwa kwe-DCM kwamanye amazwe kugcizelela amandla okukhiqiza e-China akhulayo kanye namanani ancintisanayo emakethe yomhlaba, ikakhulukazi izincibilikisi zezimboni kanye nezicelo zemithi. Abahlaziyi bathi ukukhula kubangelwa ukwanda kwesidingo esivela kwezomnotho osafufusa kanye nokulungiswa kochungechunge lokuhlinzekwa kwempahla ezimakethe ezibalulekile zase-Asia.
I-Trichloromethane: Ukuthunyelwa Kwempahla Kwehla Kwehlela Gqamisa Izinselele Zemakethe
Ukuhweba nge-Trichloromethane kupenda isithombe esibuthakathaka. NgoFebhuwari 2025, i-China yangenisa amathani angu-0.004 e-TCM angenamsebenzi, kuyilapho ukuthunyelwa kwamanye amazwe kwehle ngo-62.3% unyaka nonyaka kuya kumathani angama-40.0. Ukuthengwa kwempahla eqoqwe ngoMasingana kuya kuNhlolanja kufane nalo mkhuba, kwehle ngo-100.0% kuya kumathani angu-0.004, nokuthunyelwa kwamanye amazwe kwehle ngo-33.8% kuya kumathani angu-340.9.
I-South Korea ibibusa ukuthunyelwa kwe-TCM kwamanye amazwe, imunca u-100.0% wokuthunyelwa ngoFebhuwari (amathani angama-40.0) kanye nama-81.0% (amathani angama-276.1) ezinyangeni ezimbili zokuqala. I-Argentina neBrazil ngayinye ibalele u-7.0% (amathani angama-24.0) yenani eliphelele phakathi noJanuwari-Februwari.
Ukwehla kwezimpawu zokuthunyelwa kwe-TCM kwehlise isidingo somhlaba wonke, okungenzeka sixhunywe nemithethonqubo yezemvelo eqeda ukusetshenziswa kwazo eziqandisini kanye nokulawula okuqinile ezinhlelweni ezihlobene ne-chlorofluorocarbon (CFC). Izingqapheli zemboni ziphawula ukuthi ukugxila kweShayina kwezinye izindlela eziluhlaza kungase kubambezele nakakhulu ukukhiqizwa nokuhweba kwe-TCM esikhathini esimaphakathi.
Imiphumela Yemakethe
Izindlela ezihlukene ze-DCM ne-TCM zigqamisa amathrendi abanzi emkhakheni wamakhemikhali. Nakuba i-DCM izuza ezinhlobonhlobo zayo ekukhiqizeni nasezincibilikisini, i-TCM ibhekana nezivunguvungu ngenxa yengcindezi yokusimama. Iqhaza le-China njengomkhiqizi omkhulu we-DCM cishe lizoqina, kodwa izinhlelo zokusebenza ze-TCM zingabona ukuncipha okuqhubekayo ngaphandle uma kuvela ukusetshenziswa okusha kwezimboni.
Abathengi bomhlaba wonke, ikakhulukazi e-Asia nase-Afrika, kulindeleke ukuthi bathembele kakhulu ekuhlinzekweni kwe-DCM yase-China, kuyilapho izimakethe ze-TCM zingashintshela kubakhiqizi bamakhemikhali abakhethekile noma izifunda ezinezinqubomgomo zemvelo ezingaqinile kangako.
