Pfupiso yeChigadzirwa
N,N-Dimethylformamide (DMF) chinhu chakakosha zvikuru chinonyungudutsa cheorganic uye chemakemikari. Imvura isina ruvara uye inoonekera patembiricha yemumba, ine kunyunguduka kwakanaka uye kugadzikana kwekupisa. Ichionekwa se organic solvent yepasi rose, DMF inogona kunyungudutsa organic compounds dzakawanda uye inorganic - chinhu chinoita kuti ive chinhu chakakosha mumaindasitiri akawanda anosanganisira polyurethane, mishonga, mishonga yezvipembenene, makemikari emagetsi, dehwe rekugadzira, uye acrylic fiber spinning.
Muindasitiri yepolyurethane, DMF inoshanda senzira huru yekugadzira dehwe re polyurethane rakagadzirwa nesimbi kuburikidza nemaitiro ekunyorova uye polyurethane slurry kuburikidza nemaitiro ekuomesa. Muchikamu chemishonga, inoshanda senzira yakakosha yekuita uye solvent mukugadzirwa kwemishonga yakawanda inorwisa mabhakitiriya nemavhitamini. Muchikamu chemagetsi, DMF yakachena kwazvo inoshandiswa mukugadzira photoresist stripping ye liquid crystal panels uye kuchenesa semiconductor. Pamusoro pezvo, DMF pachayo inyanzvi yemakemikari, inoshandiswa mukugadzira mhando dzakasiyana dzemakemikari akanaka.
Zvitsva zveIndasitiri
Munguva pfupi yapfuura, musika wepasi rose weDMF wave nekuchinja kukuru. Zvichikonzerwa nekuchinja kwemitengo yezvinhu zvakagadzirwa (methanol nedimethylamine) uye shanduko mumitemo yezvakatipoteredza uye kugona kwekugadzira muChina—iyo inogadzira nevatengi veDMF pasi rose—DMF yakaona kufamba kwemitengo kwakafanana nekwekukwira kwemitengo kubva pakupera kwa2023 kusvika kutanga kwa2024. Kugadziriswa kwenzvimbo dzakawanda dzekugadzira DMF muChina muchikamu chechipiri chegore ra2024 kwakaita kuti pave nekuoma kwenguva pfupi kwekupa zvinhu uye kudzokororwa kwemitengo.
Panyaya yemutemo, kutarisirwa kwemitemo paDMF muChina kwakaramba kuchiwedzerwa. Bazi reEcology and Environment rakaisa DMF muCatalogue of Priority Control Chemicals, richiisa mitemo yakaoma yekutarisira njodzi dzezvakatipoteredza nekuchengetedzeka mukugadzirwa kwayo, kushandiswa, kuchengetwa uye kutakurwa kwayo. Izvi zvakaita kuti mamwe mabhizinesi akadai sevagadziri veganda rekugadzira vakurumidze kutsvaga nekuvandudza mashandiro ekugadzira zvinhu vachishandisa mvura. Kunyange zvakadaro, munguva pfupi kusvika pakati nepakati, DMF ichiri yakaoma kutsiviwa zvachose mumabasa akawanda.
Kubva pamiganhu yetekinoroji, tekinoroji itsva yekudzoreredza nekudzokorodza DMF zvinobudirira yapinda muchikamu chekuratidzira maindasitiri. Nekushandisa nzira itsva yekuparadzanisa membrane yemasero, tekinoroji iyi inogona kudzoreredza DMF yakachena kubva mumvura yakaoma yemaindasitiri nekushandiswa kwesimba shoma, zvichiita kuti idzoreredze huwandu hwe95%. Kukwidziridzwa kukuru kwetekinoroji iyi kuchaderedza zvakanyanya mitengo yezvinhu zvakagadziriswa uye kumanikidzwa kwekuchengetedza nharaunda kune vashandisi vari pasi pemvura.
Kuongorora Maitiro Eindasitiri
Tichitarisa mberi, indasitiri yeDMF ichakura pakati pematambudziko nemikana, ichiratidza mafambiro makuru anotevera:
Kusiyana kweMaumbirwo muKukura kweKudiwa
Kudiwa kweDMF pasi rose kunotarisirwa kupinda muchikamu chekukura kunonoka kana kuti kukwirira. Kukura muchikamu chayo chikuru chekushandisa—indasitiri yeganda repolyurethane—kunogona kudzikira pasi nekuda kwekumanikidzwa kwezvakatipoteredza uye shanduko mumusika wevatengi, uye kutotsiviwa zvishoma nemaitiro emvura asina DMF. Zvisinei, kudiwa kweDMF yakachena uye yepamusoro-soro muzvikamu zvepamusoro-soro uye zvine mutengo wakakwira zvakaita semishonga, mishonga yezvipembenene uye makemikari emagetsi kunofungidzirwa kuti kucharamba kwakasimba kana kutokura, kuchibuda sembiru yakakosha inotsigira musika weDMF.
Kubatanidzwa kweKugovera uye Kugadzirisa
Kugona kwekugadzira DMF pasi rose kwakanyanya kuzara, kunyanya muChina. Zvichienderera mberi, makwikwi muindasitiri yeDMF yeChina achachinja kubva pakuwedzera kwehuwandu hwezvinhu kuenda kumakwikwi akazara mumitengo, tekinoroji uye kuchengetedzwa kwezvakatipoteredza. Zvivako zvekumashure nezvidiki zvichabuda zvishoma nezvishoma mumusika nekuda kwekutadza kuzadzisa mitemo yakasimba yezvakatipoteredza uye kuchengetedzeka, izvo zvinotarisirwa kuwedzera huwandu hwezvinhu muindasitiri. Makambani makuru ane mukana wekushandisa zvinhu zvakagadzirwa zvakabatanidzwa (semuenzaniso, syngas dzakabatanidzwa, methanol uye dimethylamine) achawana makwikwi akawedzerwa.
Kudzivirirwa Kwezvakatipoteredza uye Kubudirira Kunogara Kwenguva Refu seMusoro Mukuru
Kutarisirwa kweDMF munzvimbo inotenderera hupenyu hwese kuchava tsika isingadzoreki, inosanganisira zvinhu zvitatu: 1) Kuchengetedza maitiro ekugadzira pachawo, akadai sekuderedza simba uye kuderedza kuburitswa kwemhepo; 2) Kushanda kwakavharwa uye kudzoreredzwa kweDMF zvinobudirira mumashandisirwo ari pasi, netekinoroji yepamusoro yekudzoreredza yataurwa pamusoro apa iri kuramba ichizivikanwa; 3) Kugadzirwa kwezvimwe zvinonyungudutsa kana maitiro asina njodzi kune zvakatipoteredza. Kunyangwe kutsiva DMF zvizere munzvimbo dzakawanda kuchiri kutora nguva, iyi ichave nzira yeR&D yenguva refu.
Kuvandudzwa Kwemhando Yepamusoro Kunokonzerwa Nemapurogiramu Epamusoro-soro
Sezvo maindasitiri epasi akadai semishonga nemagetsi achiramba achiisa zvinodiwa zvakanyanya pakuchena kwezvinhu uye kugara kwenguva refu, kudiwa kwemusika kwezvigadzirwa zveDMF zvine hunyanzvi hwepamusoro (semuenzaniso, giredhi remagetsi negiredhi remishonga) kuchakwira. Izvi zvinoda kuti vagadziri veDMF vasangowedzera huwandu hwezvigadzirwa chete, asiwo vave nehunyanzvi mukuchenesa nemazvo, kudzora mhando zvakanyanya, uye kurongedza nekutakura zvinhu zvemhando yepamusoro, vachienda kune kunatsiridza nehunyanzvi.
Kuchinja Kunogona Kuitika Mukutengeserana Kwepasi Rose
Semutengesi weDMF kunze kwenyika, mitemo yeindasitiri yeChina uye shanduko dzesimba zvicharamba zvichikanganisa zvikuru mafambiro ekutengeserana kweDMF pasi rose uye mitengo. Panguva imwecheteyo, pakufunga nezvekuchengetedzwa kwecheni yekugovera, mamwe matunhu anogonawo kuongorora kana kuvaka patsva kugona kwekugadzira DMF, kunyanya muzvikamu zvakakosha zvecheni yeindasitiri zvakaita semishonga.
Muchidimbu, semakemikari akura, musika weDMF wapinda muchikamu chekugadzirisa zvinhu uye kuvandudza chimiro. Pasinei nekumanikidzwa kubva pakutsiva nharaunda, DMF icharamba iine chinzvimbo chakakosha mumusika mune ramangwana nekuda kwekunyungudika kwayo kwakanaka uye hunhu hwayo hwekugadzirisa zvinhu hwakura mumabasa mazhinji akakosha emaindasitiri. Vachakunda mune ramangwana muindasitiri iyi vachave mabhizinesi anogona kudzora mitengo zvinobudirira, kusangana nezvinodiwa zvakasimba zvezvakatipoteredza, uye kupa zvigadzirwa zvemhando yepamusoro uye mhinduro dzekudzokorodza muminda yekushandisa zvinhu zvine kukosha kwakanyanya. Kukura kweindasitiri yeDMF kuri kuchinja kubva pakukura kukuru kuenda pakurima zvakanyanya.
