● Ubuthi obuphantsi, ivumba eliphantsi kunye nokubola kwezinto eziphilayo, okuhambelana nophuhliso lwezinyibilikisi ezinobuhlobo nokusingqongileyo
● Ixutywa neealcohols ezininzi, iiketones, ii-ethers, ii-aromatic hydrocarbons kunye nezinye izinyibilikisi, kwaye ihambelana kakuhle nefomula.
Iimeko eziphambili zokusetyenziswa kwe-n-butyl acetate:
Ishishini lokugquma: Lisetyenziswa njengesinyibilikisi esiphambili kunye nesinyibilikisi kwiingubo zomthi, iingubo zesinyithi kunye neepeyinti zokuhlaziya iimoto
Ishishini le-inki: Isinyibilikisi esibalulekileyo se-inki yokuprinta i-offset, i-gravure kunye ne-screen, ukuphucula ukucaca kokuprinta
Izincamathelisi: Zisetyenziswa kwizincamathelisi ze-PU, izincamathelisi ezibuthathaka kuxinzelelo, izincamathelisi zokulamina, njl.njl., nto leyo ephucula amandla okubopha kunye nesantya sokomisa.
Amashishini amachiza kunye nevumba elimnandi: Ukukhupha amayeza, ukuxuba ivumba elimnandi, kunye neearhente zokucoca kunye nokukhupha ivumba kwimizi-mveliso

2. Iindaba zamva nje zoshishino ze-n-Butyl Acetate
Ukususela ekuqaleni kuka-2026, utshintsho olukhulu lwenzekile kumacandelo emarike nakwimizi-mveliso ye-n-butyl acetate, nto leyo etyhalela eli shishini kumjikelo omtsha.
1. Uphuhliso lwendawo ye-n-butyl acetate ephezulu
Amashishini aliqela asekhaya aphumelele ukuvelisa i-n-butyl acetate ye-elektroniki kunye ne-n-butyl acetate ye-pharmaceutical-grade ngobuninzi obucocekileyo obungaphezulu kwe-99.95%. Izalathisi zee-ion zesinyithi kunye nokufuma zifikelele kumanqanaba aphezulu aphesheya, ziphula ukuxhomekeka kwexesha elide kwizinto ezingeniswa kwamanye amazwe. I-n-butyl acetate ecocekileyo kakhulu ingenile kwiikhonkco zobonelelo lwamandla amatsha, ukucoca kwe-semiconductor kunye nee-inki zokupakisha eziphezulu.
2. Iinkqubo eziluhlaza zikhawulezisa ukutshintshwa kweenkqubo zemveli
Iinkqubo ezintsha zokuvelisa i-n-butyl acetate kusetyenziswa i-solid acid catalysis kunye ne-continuous reactive distillation ziya zithandwa ngokukhawuleza. Xa kuthelekiswa nendlela yendabuko ye-sulfuric acid, ukukhutshwa kwe-waste acid kuncitshiswa ngaphezulu kwe-90%, kwaye ukusetyenziswa kwamandla kuncitshiswa ngama-25%–30%. Abavelisi abaphambili be-n-butyl acetate bagqibe ukuhlaziya ubuchwephesha ukuze bafezekise imveliso eluhlaza kunye nekhabhoni ephantsi.
3. Ubonelelo, imfuno kunye nokuguquguquka kwamaxabiso e-n-butyl acetate
NgoFebruwari 2026, echatshazelwe kukuqalisa kwakhona komsebenzi emva koMnyhadala weNtwasahlobo, imakethi ye-n-butyl acetate yahlala izinzile ngokubanzi, amaxabiso entengiselwano aqhelekileyo eMpuma China aqala kwi-5,500 ukuya kwi-5,800 RMB/ton. Ngokubuyela kancinci kancinci kwamashishini okugquma, ukupakisha kunye nokuncamathelisa, imfuno kunye namaxabiso e-n-butyl acetate kulindeleke ukuba angene kwitshaneli ebuyela umva ukususela ngoMatshi.
