Hauv cov tshuaj lom neeg niaj hnub no, cov tshuaj pleev xim thiab cov kua mem, n-butyl acetate tau siv dav thiab ruaj khov ua cov tshuaj organic solvent. Vim nws muaj zog yaj tau zoo, qhov ceev ntawm kev yaj nruab nrab thiab kev sib haum xeeb zoo heev, n-butyl acetate tau tswj hwm txoj haujlwm tseem ceeb hauv kev lag luam tshuaj tau ntev. Nrog rau cov cai ib puag ncig nruj dua thiab kev nce ntawm kev tsim khoom siab, n-butyl acetate tab tom hloov pauv sai sai los ntawm cov tshuaj yaj ib txwm mus rau cov khoom ntsuab, siab thiab tshwj xeeb, ua ib qho ntawm cov ntu loj hlob tshaj plaws hauv kev lag luam tshuaj lom neeg.
1. Kev Taw Qhia Luv Luv Txog n-Butyl Acetate
n-Butyl acetate (tseem hu ua n-butyl ethanoate, CAS: 123-86-4) yog cov tshuaj organic tsis muaj xim, pob tshab nrog ntxhiab tsw qab txiv hmab txiv ntoo. Nws muaj cov mis molecular ntawm C₆H₁₂O₂, lub ntsiab lus kub ntawm kwv yees li 126 ° C, thiab cov khoom tshuaj ruaj khov.
Cov txiaj ntsig tseem ceeb ntawm n-butyl acetate:
● Kev yaj zoo heev rau nitrocellulose, acrylic resins, polyurethane, roj hmab ntuj thiab lwm yam khoom siv
● Tus nqi volatilization nruab nrab thiab kev ua tau zoo leveling, dav siv rau kev txheej thiab cov ntawv thov number case
● Tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis lwj, ua raws li kev tsim cov tshuaj yaj uas zoo rau ib puag ncig
● Sib xyaw nrog feem ntau cov cawv, ketones, ethers, aromatic hydrocarbons thiab lwm cov kuab tshuaj, nrog rau kev sib raug zoo ntawm cov mis
Cov xwm txheej tseem ceeb ntawm daim ntawv thov n-butyl acetate:
Kev lag luam txheej: Siv ua cov kuab tshuaj tseem ceeb thiab diluent rau cov txheej ntoo, cov txheej hlau thiab cov xim pleev xim rau tsheb
Kev lag luam kua mem: Cov kuab tshuaj tseem ceeb rau cov kua mem luam tawm, gravure thiab screen printing, txhim kho kev luam ntawv meej
Cov nplaum: Siv rau hauv PU nplaum, cov nplaum rhiab siab, cov nplaum laminating, thiab lwm yam, txhim kho lub zog sib txuas thiab qhov ceev kom qhuav.
Kev lag luam tshuaj thiab tshuaj tsw qab: Kev rho tawm tshuaj, kev sib xyaw tshuaj tsw qab, nrog rau cov neeg ua haujlwm ntxuav thiab rho tawm hauv kev lag luam

2. Xov Xwm Kev Lag Luam Tshiab Tshaj Plaws ntawm n-Butyl Acetate
Txij li thaum pib xyoo 2026, kev hloov pauv tseem ceeb tau tshwm sim hauv kev ua lag luam thiab kev lag luam ntawm n-butyl acetate, thawb kev lag luam mus rau hauv lub voj voog tshiab.
1. Kev tshawb nrhiav qhov chaw ntawm cov khoom siv n-butyl acetate siab
Muaj ntau lub tuam txhab lag luam hauv tsev tau ua tiav hauv kev tsim cov khoom siv hluav taws xob n-butyl acetate thiab cov tshuaj n-butyl acetate nrog kev ntshiab siab dua 99.95%. Cov cim qhia ntawm cov hlau ions thiab cov dej noo tau mus txog qib siab thoob ntiaj teb, rhuav tshem kev vam khom mus sij hawm ntev rau kev xa khoom tuaj. Cov khoom n-butyl acetate uas muaj kev ntshiab siab tau nkag mus rau hauv cov saw hlau ntawm lub zog tshiab, kev ntxuav semiconductor thiab cov kua ntim khoom zoo.
2. Cov txheej txheem ntsuab ua kom cov txheej txheem ib txwm hloov pauv sai dua
Cov txheej txheem tshiab rau kev tsim n-butyl acetate siv cov khoom siv catalysis acid thiab kev sib xyaw ua ke tas mus li tau txais kev nyiam sai sai. Piv nrog rau txoj kev sulfuric acid ib txwm muaj, cov pa phem ntawm cov kua qaub pov tseg raug txo ntau dua 90%, thiab kev siv hluav taws xob raug txo qis los ntawm 25% -30%. Cov neeg tsim khoom n-butyl acetate ua ntej tau ua tiav kev kho dua tshiab kom ua tiav kev tsim khoom ntsuab thiab qis carbon.
3. Kev muab khoom, kev thov thiab tus nqi dynamics ntawm n-butyl acetate
Thaum Lub Ob Hlis 2026, cuam tshuam los ntawm kev rov pib ua haujlwm tom qab Lub Caij Nplooj Ntoos Hlav, kev lag luam n-butyl acetate feem ntau tseem ruaj khov, nrog rau cov nqi pauv lag luam hauv Sab Hnub Tuaj Suav teb txij li 5,500 txog 5,800 RMB / ton. Nrog rau kev rov qab los ntawm kev lag luam txheej, ntim khoom thiab nplaum, kev thov thiab tus nqi ntawm n-butyl acetate yuav tsum nkag mus rau hauv qhov channel rov qab pib thaum Lub Peb Hlis.

3. Kev Lag Luam ntawm n-Butyl Acetate
Hauv 3-5 xyoos tom ntej no, kev lag luam n-butyl acetate yuav txhim kho peb txoj kab tseem ceeb: kev ntsuab, kev txhim kho siab thiab kev tsom mus rau ib puag ncig.
3.1 Cov cai ib puag ncig tsav n-butyl acetate los hloov cov kuab tshuaj VOC siab
Nrog rau kev tswj hwm VOC hauv tebchaws thiab kev cai lij choj EU REACH uas nruj dua, cov tshuaj lom neeg thiab cov ntxhiab tsw phem maj mam tawm ntawm kev ua lag luam. Vim nws tsis muaj tshuaj lom, lwj thiab tsis ua rau ib puag ncig puas tsuaj, n-butyl acetate tau dhau los ua lwm txoj hauv kev xaiv, nrog rau kev nkag mus rau hauv cov khoom ntim khoom noj, cov khoom siv rau menyuam yaus, cov tshuaj pleev xim rau tsheb thiab lwm yam teb.
3.2 Cov ntawv thov siab kawg tau dhau los ua lub cav loj hlob rau n-butyl acetate
Kev loj hlob ntawm cov tshuaj n-butyl acetate uas yog cov tshuaj yaj tau qeeb zuj zus, thaum qhov kev thov rau cov khoom siv hluav taws xob n-butyl acetate, cov khoom siv tshuaj n-butyl acetate thiab cov khoom siv photovoltaic n-butyl acetate loj hlob ntau dua 15% hauv ib xyoos. Cov khoom siv tshwj xeeb n-butyl acetate uas muaj kev ntshiab siab, tsis muaj kuab paug ntau thiab cov dej noo tsawg yuav dhau los ua lub hauv paus ntawm kev lag luam thiab kev sib tw.
3.3 Kev nce siab ntawm kev lag luam, cov tuam txhab ua lag luam tseem ceeb tswj hwm kev lag luam n-butyl acetate
Cov chav n-butyl acetate me me, qub dhau lawm thiab ua rau muaj kuab paug ntau heev tab tom tawm hauv kev lag luam tas li. Cov lag luam loj sib koom ua ke tab tom nthuav lawv cov feem ntawm kev lag luam ua tsaug rau kev sib koom ua ke ntawm cov khoom siv raw, cov txiaj ntsig ntawm tus nqi thiab kev ua raws li ib puag ncig. Kev lag luam n-butyl acetate yav tom ntej yuav muaj tus qauv ntawm "kev tsom mus rau sab saum toj thiab kev coj noj coj ua hauv cov khoom kim heev".
3.4 Bio-based n-butyl acetate qhib ib txoj kev tshiab
Bio-based n-butyl acetate, uas tsim los ntawm bio-fermented n-butanol, tau nkag mus rau theem sim thiab kev lag luam, nrog rau cov pa roj carbon tsawg dua 40% piv rau txoj kev petrochemical. Daim ntawv pov thawj ntsuab thiab kev xa khoom qis carbon yuav ua rau muaj kev sib tw ntawm bio-based n-butyl acetate yav tom ntej.
Xaus lus
n-butyl acetate zoo li cov tshuaj yaj hauv kev lag luam, tab sis nws yog cov khoom siv tseem ceeb rau kev pleev xim, kua mem, nplaum thiab kev tsim khoom siab. Tsav los ntawm kev txhim kho ib puag ncig thiab kev hloov pauv hauv kev lag luam, n-butyl acetate tab tom hloov ntawm "cov khoom loj thiab pheej yig" mus rau "zoo thiab muaj nqis". Cov lag luam uas tau txais txiaj ntsig hauv cov txheej txheem ntsuab, cov khoom lag luam siab thiab kev ruaj khov ntawm cov khoom xa tuaj yuav ua tus thawj coj hauv kev loj hlob tom ntej ntawm n-butyl acetate.
