Ukubuka Konke Komkhiqizo
I-N,N-Dimethylformamide (DMF) iyisinyibilikisi esibaluleke kakhulu sezinto eziphilayo kanye nezinto zokusetshenziswa zamakhemikhali. Iwuketshezi olungenambala futhi olubonakalayo ekushiseni kwegumbi, olunokuncibilika okuhle kakhulu kanye nokuqina kokushisa. Njengoba ibhekwa njengesinyibilikisi sezinto eziphilayo esijwayelekile, i-DMF ingancibilikisa amakhemikhali amaningi ezinto eziphilayo kanye nezinga-organic—isici esiyenza ibe yingxenye ebalulekile emikhakheni eminingi yezimboni okuhlanganisa i-polyurethane, imithi, izibulala-zinambuzane, amakhemikhali kagesi, isikhumba sokwenziwa, kanye nokusonta i-acrylic fiber.
Embonini ye-polyurethane, i-DMF isebenza njengesithako esiyinhloko sokukhiqizwa kwesikhumba esenziwe nge-polyurethane ngenqubo emanzi kanye ne-polyurethane slurry ngenqubo eyomile. Ngaphakathi komkhakha wezokwelapha, isebenza njengendawo ebalulekile yokusabela kanye nesithako ekuhlanganisweni kwama-antibiotic amaningi namavithamini. Ensimini ye-elekthronikhi, i-DMF ehlanzekile kakhulu isetshenziswa ekuhlungeni kwe-photoresist kwamaphaneli e-liquid crystal kanye nokuhlanza kwe-semiconductor. Ngaphezu kwalokho, i-DMF ngokwayo iyi-intermediate ebalulekile yamakhemikhali, engasetshenziswa ekwakheni amakhemikhali ahlukahlukene amahle.
Intuthuko Yamuva Yemboni
Muva nje, imakethe yomhlaba wonke ye-DMF ibhekane noshintsho oluphawulekayo. Iqhutshwa ukuguquguquka kwamanani ezinto zokusetshenziswa eziphezulu (i-methanol ne-dimethylamine) kanye nezinguquko ezinqubweni zemvelo kanye namandla okukhiqiza eShayina—umkhiqizi omkhulu we-DMF kanye nomthengi—i-DMF ibone ukunyakaza kwentengo okufana ne-rollercoaster kusukela ekupheleni kuka-2023 kuya ekuqaleni kuka-2024. Ukugcinwa okuhlanganisiwe kwezindawo eziningana ezinkulu zokukhiqiza i-DMF eShayina kwikota yesibili ka-2024 kwaholela ekuqineni kwesikhashana kokunikezwa kanye nokubuyela emuva kwentengo okwalandela.
Ngasohlangothini lwenqubomgomo, ukuqapha okulawulwayo kwe-DMF eShayina kuye kwaqiniswa njalo. UMnyango Wezemvelo Nezemvelo ufake i-DMF kuKhathalogu Yamakhemikhali Okulawula Okubalulekile, wabeka izidingo zokuphatha eziqinile ezingozini zemvelo nezokuphepha kulo lonke ukukhiqizwa kwayo, ukusetshenziswa, ukugcinwa kanye nokuthuthwa. Lokhu kushukumisele amanye amabhizinisi angaphansi komhlaba njengabakhiqizi besikhumba sokwenziwa ukuthi basheshise i-R&D yokushintsha inqubo esekelwe emanzini. Noma kunjalo, esikhathini esifushane kuya kweside, i-DMF isalokhu kunzima ukuyishintsha ngokuphelele ezinqubweni eziningi.
Kusukela emingceleni yezobuchwepheshe, ubuchwepheshe obusha bokubuyisa nokuvuselela i-DMF ngempumelelo bungene esigabeni sokuboniswa kwezimboni. Ngokwamukela inqubo entsha yokuhlukanisa ulwelwesi lwesihlungo sama-molecule, lobu buchwepheshe bungabuyisa i-DMF ehlanzekile kakhulu emanzini amdaka ezimboni ayinkimbinkimbi ngokusetshenziswa kwamandla okuphansi, kufinyelelwe izinga lokubuyisa elingaphezu kuka-95%. Ukukhuthazwa okukhulu kwalolu buchwepheshe kuzonciphisa kakhulu izindleko zezinto zokusetshenziswa kanye nengcindezi yokuthobela imvelo kubasebenzisi abangaphansi komfula.
Ukuhlaziywa Kwendlela Yomkhakha
Uma sibheka phambili, imboni ye-DMF izothuthuka phakathi kwezinselelo namathuba, iveze lezi zindlela ezilandelayo ezibalulekile:
Ukwehluka Kwesakhiwo Ekukhuleni Kwesidingo
Isidingo somhlaba wonke se-DMF kulindeleke ukuthi singene esigabeni sokukhula okuhamba kancane noma ithafa. Ukukhula emkhakheni wayo wendabuko omkhulu wokusetshenziswa—imboni yesikhumba esenziwe nge-polyurethane—kungase kwehle ijubane ngaphansi kwengcindezi yemvelo kanye nezinguquko emakethe yabathengi, futhi kuthathelwe indawo ngokwengxenye yizinqubo ezisekelwe emanzini ezingenayo i-DMF. Kodwa-ke, isidingo se-DMF ehlanzekile, esezingeni eliphezulu emikhakheni ephezulu neyenenani eliphezulu njengemithi, izibulala-zinambuzane kanye namakhemikhali kagesi kulindeleke ukuthi sihlale sizinzile noma sikhule, sivele njengensika ebalulekile esekela imakethe ye-DMF.
Ukuhlanganiswa Nokuthuthukiswa Kokuphakelwa Komkhiqizo
Amandla okukhiqiza i-DMF emhlabeni wonke agxile kakhulu, ikakhulukazi eShayina. Kusukela manje, ukuncintisana embonini ye-DMF yaseShayina kuzoshintsha kusuka ekukhuleni okumsulwa kuye ekuncintisaneni okuphelele kwezindleko, ubuchwepheshe kanye nokuvikelwa kwemvelo. Izikhungo ezibuyela emuva nezincane zizophuma kancane kancane emakethe ngenxa yokwehluleka ukuhlangabezana nezindinganiso eziqinile zemvelo nokuphepha, okulindeleke ukuthi zithuthukise ukugxilwa kwemboni. Amabhizinisi amakhulu anezinzuzo ezintweni zokusetshenziswa ezihlanganisiwe (isib. i-syngas ehlanganisiwe, i-methanol kanye ne-dimethylamine) azothola ukuncintisana okuthuthukisiwe.
Ukuvikelwa Kwemvelo kanye Nentuthuko Eqhubekayo njengezihloko Eziyinhloko
Ukuphathwa kwemvelo kwe-DMF ngomjikelezo wokuphila kuzoba umkhuba ongenakuguqulwa, ohlanganisa izici ezintathu: 1) Ukwenziwa luhlaza kwezinqubo zokukhiqiza ngokwazo, njengokunciphisa amandla kanye nokunciphisa ukukhishwa komoya; 2) Ukusebenza okuvaliwe kanye nokubuyiselwa kwe-DMF okuphumelelayo ezisetshenziswayo ezansi, kanye nobuchwepheshe bokubuyisela obuthuthukisiwe obushiwo ngenhla buqala ukuthandwa kakhulu; 3) Ukuthuthukiswa kwezinyibilikisi noma izinqubo ezihlukile ezinobungani nemvelo. Nakuba ukushintshwa okuphelele kwe-DMF emikhakheni eminingi kusathatha isikhathi, lokhu kuzoba yisiqondiso sesikhathi eside se-R&D.
Ukuthuthukiswa Kwekhwalithi Okuqhutshwa Izinhlelo Zokusebenza Ezisezingeni Eliphezulu
Njengoba izimboni ezingezansi ezifana nemithi kanye ne-elekthronikhi zibeka izidingo eziphakeme kakhulu ekuhlanzekeni kwezinto ezibonakalayo kanye nokuvumelana, isidingo semakethe semikhiqizo ye-DMF ecacisiwe kakhulu (isb., izinga le-elekthronikhi kanye nezinga lemithi) sizokhuphuka. Lokhu kudinga abakhiqizi be-DMF ukuthi bangagcini nje ngokwandisa izinga lokukhiqiza, kodwa futhi babe namakhono okuhlanzwa ngokunemba, ukulawula ikhwalithi okuqinile, kanye nokupakisha kanye nokuthuthwa okujwayelekile, okuqhubekela phambili ekuthuthukisweni nasekukhetheni okukhethekile.
Izinguquko Ezingaba Khona Ephethini Lokuhweba Lomhlaba Wonke
Njengomthengisi we-DMF, izinqubomgomo zezimboni zaseShayina kanye nezinguquko zamandla zizoqhubeka nokuba nomthelela omkhulu ekuhambeni kokuhweba kwe-DMF emhlabeni wonke kanye namanani. Okwamanje, ngenxa yokucabangela ukuphepha kwe-supply chain, ezinye izifunda zingase zihlole noma zakhe kabusha amandla okukhiqiza e-DMF angaphelele, ikakhulukazi ekuxhumaneni okubalulekile kwe-industrial chain njengemithi.
Ngamafuphi, njengekhemikhali eyisisekelo evuthiwe, imakethe ye-DMF isingene esigabeni sokuthuthukisa isitokwe kanye nokuthuthukiswa kwesakhiwo. Naphezu kokubhekana nengcindezi evela ekushintsheni kwemvelo, i-DMF izogcina isikhundla esibalulekile semakethe esikhathini esizayo esibonakalayo ngenxa yokuncibilika kwayo okuhle kakhulu kanye nezakhiwo zokucubungula ezivuthiwe ezinqubweni eziningi ezibalulekile zezimboni. Abaphumelele embonini yesikhathi esizayo kuzoba amabhizinisi angalawula ngempumelelo izindleko, ahlangabezane nezindinganiso eziqinile zemvelo, futhi ahlinzeke ngemikhiqizo esezingeni eliphezulu kanye nezixazululo zokuvuselela kabusha emikhakheni yesicelo enenani eliphezulu. Ukuthuthukiswa kwemboni ye-DMF kuyashintsha kusuka ekwandeni okukhulu kuya ekulimeni okujulile.
