Emaketangeni ezimboni amakhemikhali amahle, okokumboza kanye noyinki wesimanje, i-n-butyl acetate ibilokhu iyi-solvent eyisisekelo esetshenziswa kabanzi futhi ezinzile. Ngenxa yamandla ayo okuncibilikisa aqinile, izinga lokuguquguquka eliphakathi kanye nokuhambisana okuhle kakhulu, i-n-butyl acetate igcine isikhundla esibalulekile emakethe ye-solvent isikhathi eside. Ngezinqubomgomo zemvelo eziqinile kanye nokwanda kokukhiqiza okuphezulu, i-n-butyl acetate ishintsha ngokushesha isuka ku-solvent yendabuko enkulu iye kumkhiqizo oluhlaza, ophezulu futhi okhethekile, iba ngesinye sezigaba ezikhula kakhulu emkhakheni we-solvent yamakhemikhali.
1. Isingeniso Esifushane ku-n-Butyl Acetate
I-n-Butyl acetate (eyaziwa nangokuthi i-n-butyl ethanoate, i-CAS: 123-86-4) iyi-solvent ephilayo engenambala, ecacile nengakhethi enephunga elimnandi lezithelo. Inefomula yama-molecule ye-C₆H₁₂O₂, iphuzu lokubila elingaba ngu-126°C, kanye nezakhiwo zamakhemikhali ezizinzile.
Izinzuzo eziyinhloko ze-n-butyl acetate:
● Ukuncibilika okuvelele kwe-nitrocellulose, ama-resin e-acrylic, i-polyurethane, irabha yemvelo nezinye izinto
● Izinga lokuguquguquka eliphakathi nendawo kanye nokusebenza okuhle kokulinganisa, okulungele kakhulu ukusetshenziswa kokumboza kanye noyinki
● Ubuthi obuphansi, iphunga eliphansi kanye nokubola, okuhambisana nokuthuthukiswa kwezinyibilikisi ezinobungani nemvelo
● Ixubene nezinhlobo eziningi ze-alcohols, ama-ketone, ama-ether, ama-hydrocarbon aromatic kanye nezinye izinyibilikisi, futhi ihambisana kahle nefomula
Izimo eziyinhloko zokusetshenziswa kwe-n-butyl acetate:
Imboni yokumboza: Isetshenziswa njengesithako esiyinhloko kanye nesihlanzisi sezinto zokumboza ngokhuni, izinto zokumboza ngensimbi kanye nopende wokuhlanza izimoto
Imboni ye-inki: Isithako esiyinhloko sama-inki okuphrinta nge-offset, gravure kanye nesikrini, okuthuthukisa ukucaca kokuphrinta
Izinamathiseli: Zisetshenziswa kuzinamathiseli ze-PU, izinamathiseli ezizwela ukucindezeleka, izinamathiseli ezinamathelayo, njll., okuthuthukisa amandla okubopha kanye nesivinini sokomisa
Izimboni zemithi kanye nephunga elimnandi: Ukukhipha imithi, ukuxuba amaphunga, kanye nezinsiza zokuhlanza nokukhipha izimboni

2. Izindaba Zakamuva Zemboni ze-n-Butyl Acetate
Kusukela ekuqaleni kuka-2026, kube nezinguquko ezibalulekile emakethe kanye nasezimbonini ze-n-butyl acetate, okwenze imboni yangena emjikelezweni omusha.
1. Ukuthuthukiswa kwendawo kwe-n-butyl acetate ephezulu
Amabhizinisi amaningana asekhaya aphumelele ukukhiqiza i-n-butyl acetate ye-elekthronikhi kanye ne-n-butyl acetate yezinga lemithi ngobumsulwa obungaphezu kuka-99.95%. Izinkomba zama-ion ensimbi kanye nomswakama sezifinyelele emazingeni aphezulu emhlabeni jikelele, zaphula ukuncika kwesikhathi eside ekungenisweni kwempahla. I-n-butyl acetate ehlanzekile kakhulu isingene emigqeni yokuphakelwa kwamandla amasha, ukuhlanza kwe-semiconductor kanye noyinki wokupakisha ophezulu.
2. Izinqubo eziluhlaza zisheshisa ukufakwa esikhundleni kwezinqubo zendabuko
Izinqubo ezintsha zokukhiqiza i-n-butyl acetate kusetshenziswa i-solid acid catalysis kanye ne-continuous reactive distillation ziyathandwa ngokushesha. Uma kuqhathaniswa nendlela yendabuko ye-sulfuric acid, ukukhishwa kwe-waste acid kuncishiswa ngaphezu kuka-90%, kanti ukusetshenziswa kwamandla kwehla ngo-25%–30%. Abakhiqizi abahamba phambili be-n-butyl acetate baqedele ukulungiswa kobuchwepheshe ukuze bafeze ukukhiqizwa okuluhlaza kanye ne-carbon ephansi.
3. Ukuhlinzeka, isidingo kanye nokuguquguquka kwentengo ye-n-butyl acetate
NgoFebhuwari 2026, ethintekile ukuqaliswa kabusha komsebenzi ngemva koMkhosi weNtwasahlobo, imakethe ye-n-butyl acetate yahlala izinzile, ngamanani okuthengiselana ajwayelekile eMpumalanga China asukela ku-5,500 kuya ku-5,800 RMB/ton. Ngokululama kancane kancane kwezimboni zokumboza, ukupakisha kanye nokunamathela, isidingo kanye namanani e-n-butyl acetate kulindeleke ukuthi angene esiteshini sokubuya kabusha kusukela ngoMashi.

3. Izitayela Zemboni ze-n-Butyl Acetate
Eminyakeni emi-3-5 ezayo, imboni ye-n-butyl acetate izothuthuka cishe emigqeni emithathu eyinhloko: ukukhulisa i-greening, intuthuko ephezulu kanye nokugxila.
3.1 Izinqubomgomo zemvelo ziqhuba i-n-butyl acetate ukuthi ithathe indawo yezinyibilikisi ezine-VOC ephezulu
Ngemithethonqubo eqinile yokuphatha i-VOC yasekhaya kanye nomthetho we-EU REACH, izinyibilikisi ezinobuthi kakhulu nezinuka kabi ziyahoxa kancane kancane emakethe. Ngenxa yobuthi bayo obuphansi, ukubola kanye nokukhishwa kwayo okunobungani nemvelo, i-n-butyl acetate isibe yindlela ekhethwayo, ngokuqhubeka nokungena emaphaketheni okudla, imikhiqizo yezingane, izembozo zezimoto kanye neminye imikhakha.
3.2 Izinhlelo zokusebenza eziphezulu ziba yinjini eyinhloko yokukhula kwe-n-butyl acetate
Ukukhula kwe-n-butyl acetate ejwayelekile ye-solvent-grade kuyehla, kuyilapho isidingo se-n-butyl acetate ye-electronic-grade, i-n-butyl acetate ye-pharmaceutical-grade kanye ne-n-butyl acetate ye-photovoltaic-grade sikhula ngaphezu kuka-15% ngonyaka. I-n-butyl acetate ye-special-grade enokuhlanzeka okuphezulu, ukungcola okuphansi kanye nokuqukethwe okuphansi komswakama kuzoba yisisekelo senzuzo yenkampani kanye nokuncintisana.
3.3 Ukwanda kokuhlushwa kwezimboni, amabhizinisi ahola phambili abusa imakethe ye-n-butyl acetate
Amayunithi amancane, aphelelwe yisikhathi futhi angcolisa kakhulu i-n-butyl acetate aqhubeka nokuphuma emakethe. Amabhizinisi amakhulu ahlanganisiwe andisa isabelo sawo semakethe ngenxa yokuhlanganiswa kwezinto zokusetshenziswa, izinzuzo zezindleko kanye nokuhambisana nemvelo. Imakethe ye-n-butyl acetate yesikhathi esizayo izoba nephethini "yokugxila phezulu kanye nobuholi ezigabeni eziphezulu".
3.4 I-n-butyl acetate esekelwe kwi-bio ivula ithrekhi entsha
I-n-butyl acetate esekelwe ku-bio, ekhiqizwa nge-n-butanol evundisiwe nge-bio, isingene ezigabeni zokuhlola kanye nokuthuthukiswa kwezimboni, lapho ukukhishwa kwekhabhoni kungaphansi ngo-40% kunomzila we-petrochemical. Isitifiketi esiluhlaza kanye nokuthunyelwa kwamanye amazwe okunekhabhoni ephansi kuzothuthukisa kakhulu ukuncintisana kwe-n-butyl acetate esekelwe ku-bio esikhathini esizayo.
Isiphetho
I-n-butyl acetate ingase ibonakale njenge-solvent evamile yezimboni, kodwa iyinto eyisisekelo ebalulekile yokugqoka, uyinki, izinamathiseli kanye nokukhiqizwa kwekhwalithi ephezulu. Iqhutshwa kokubili ukuthuthukiswa kwemvelo kanye nokuguqulwa kwezimboni, i-n-butyl acetate ishintsha isuka "enkulu futhi engabizi kakhulu" iye "ekhwalithini ephezulu kanye nenani eliphezulu". Amabhizinisi athola izinzuzo ezinqubweni eziluhlaza, imikhiqizo ephezulu kanye nokuzinza kochungechunge lokuhlinzekwa azohola emzuliswaneni olandelayo wokukhula kwe-n-butyl acetate.
