Marka loo eego xogta kastamka ee ugu dambeysay, dhaqdhaqaaqa ganacsi ee Shiinaha ee dichloromethane (DCM) iyo trichloromethane (TCM) bishii Febraayo 2025 iyo labadii bilood ee ugu horreeyay sanadka ayaa muujiyay isbeddello is burinaya, oo muujinaya isbeddelka baahida caalamiga ah iyo awoodaha wax soo saarka gudaha.
Dichloromethane: Dhoofinta Kobaca Wadida
Bishii Febraayo 2025, Shiinuhu waxa uu soo dhoofiyay 9.3 tan oo dichloromethane ah, taas oo muujinaysa koror la yaab leh 194.2% sanadba sanadka ka dambeeya. Si kastaba ha ahaatee, isugaynta soo dejinta ee Janaayo-February 2025 ayaa wadartoodu ahayd 24.0 tan, oo hoos u dhacday 64.3% marka la barbar dhigo isla muddadaas 2024.
Dhoofintu waxay sheegtay sheeko kale. Febraayo waxa la dhoofiyay 16,793.1 tan DCM, 74.9% kor u kac sanadba sanadka ka dambeeya, halka dhoofinta isu geynta labadii bilood ee ugu horeysay ay gaartay 31,716.3 tan, ilaa 34.0%. Kuuriyada Koonfureed ayaa noqotay meesha ugu sarreysa bishii Febraayo, iyada oo soo dejisa 3,131.9 tan (18.6% wadarta dhoofinta), waxaa ku xiga Turkiga (1,675.9 tan, 10.0%) iyo Indonesia (1,658.3 tan, 9.9%). Jannaayo-Febraayo, Kuuriyada Koonfureed ayaa hoggaanka ku sii heysatay 3,191.9 tan (10.1%), halka Nigeria (2,672.7 tan, 8.4%) iyo Indonesia (2,642.3 tan, 8.3%) ay kor u kaceen.
Korodhka fiiqan ee dhoofinta DCM waxay hoosta ka xariiqaysaa ballaarinta awoodaha wax soo saarka Shiinaha iyo qiimaha tartanka ee suuqa caalamiga ah, gaar ahaan dareerayaasha warshadaha iyo codsiyada dawooyinka. Falanqeeyayaasha ayaa kobaca u nisbaynaya baahida korodhay ee ka imanaysa dhaqaalaha soo koraya iyo hagaajinta silsiladda sahayda ee suuqyada muhiimka ah ee Aasiya.
Trichloromethane: Dhoofintu waxay hoos u dhigtay Caqabadaha Suuqa
Ganacsiga Trichloromethane wuxuu sameeyay sawir daciif ah. Bishii Febraayo 2025, Shiinuhu waxa uu soo dejiyay 0.004 tan oo TCM ah oo dayacan, halka dhoofinta ay hoos u dhacday 62.3% sannad kasta ilaa 40.0 tan. Soo dejinta Janawari-Febraayo ayaa isugaysay isbeddelkan, oo hoos ugu dhacay 100.0% ilaa 0.004 tan, iyada oo wax dhoofinta ay hoos u dhacday 33.8% ilaa 340.9 tan.
Kuuriyada Koonfureed ayaa xukuntay Dhoofinta TCM, iyada oo nuugaysa 100.0% shixnadaha bishii Febraayo (40.0 tan) iyo 81.0% (276.1 tan) labadii bilood ee ugu horreeyay. Argentina iyo Brazil ayaa mid walbaa ka ahaa 7.0% (24.0 tan) wadarta guud intii lagu jiray Janaayo-Febraayo.
Hoos u dhaca dhoofinta TCM calaamadaha ayaa hoos u dhigay baahida caalamiga ah, oo suurtagal ah in lala xiriiriyo xeerarka deegaanka oo meesha ka saaraya isticmaalkeeda qaboojiyaha iyo kontaroolada adag ee codsiyada la xiriira chlorofluorocarbon (CFC). Kormeerayaasha warshaduhu waxay xuseen in diiradda Shiinuhu ee beddelka cagaarka ah laga yaabo inay sii xannibaan wax soo saarka TCM iyo ganacsiga muddada dhexe.
Saamaynta Suuqa
Dariiqooyinka kala duwan ee DCM iyo TCM waxay muujinayaan isbeddellada ballaaran ee qaybta kiimikooyinka. Iyadoo DCM ay ka faa'iidaysanayso wax-soo-saarka iyo dareeraha, TCM waxay wajaheysaa dabaylo madaxeed sababtoo ah cadaadiska joogtada ah. Doorka Shiinaha ee dhoofiyaha weyn ee DCM waxay u badan tahay inuu sii xoogeysto, laakiin codsiyada TCM ee niche waxay arki karaan qandaraas sii socda ilaa isticmaalka cusub ee warshadaha soo baxaan.
Iibsadayaasha caalamiga ah, gaar ahaan Aasiya iyo Afrika, ayaa la filayaa inay si sii kordheysa ugu tiirsanaadaan sahayda Shiinaha ee DCM, halka suuqyada TCM laga yaabo inay u wareegaan soosaarayaasha kiimikada gaarka ah ama gobollada leh siyaasado deegaan oo adag.
