Colourless meej meej 99.5% Kua Ethyl acetate rau qib kev lag luam
Kev siv
Ethyl acetate yog ib qho kev muaj cov kuab tshuaj zoo heev thiab tuaj yeem siv hauv cov roj hmab nitrate, cellulose roj hmab, zoo li hauv cov kua nroog Nitro fiber ntau rau photocopers. Yuav siv tau raws li nplaum hnyav, xim nyias. Siv raws li kev tshawb xyuas reagent, cov qauv tshuaj thiab cov kuab tshuaj rau chromatographic tsom xam. Hauv kev lag luam textile tuaj yeem siv los ua tus neeg saib xyuas kev tu, hauv kev hloov khoom noj cawv txiv hmab txiv ntoo sib txawv, tab sis kuj siv cov tshuaj uas organic acid extraction. Ethyl acetate kuj tau siv los ua kom tuag, cov tshuaj thiab txuj lom.
Cia yog nyob rau chav tsev kub thiab yuav tsum khaws pa thiab qhuav, zam kev rau lub hnub thiab av noo. Ethyl acetate tuaj yeem ua paug los ntawm combustibles, oxidants, muaj zog acids thiab lub hauv paus, thiab yog li ntawd yuav tsum tau sib cais los ntawm cov tshuaj uas khaws cia thiab siv kom tsis txhob muaj kev phom sij.
Daim Ntawv Thov Kev Pab Cuam
Ethyl acetate muaj ntau cov kev siv. Qee qhov chaw tsim khoom loj thiab siv tau suav nrog:
1. Ntau lawm hauv cov chaw xws li tshuaj pleev ib ce, kev saib xyuas tus kheej thiab tshuaj tsw qab.
2. Kev tsim cov dyes, resins, txheej thiab inks, raws li cov kuab tshuaj.
3. Hauv kev lag luam kws tshuaj, nws tuaj yeem siv los ua cov kuab tshuaj thiab kev rho tawm.
4. Siv cov zaub mov thiab dej qab zib, hauv npias, dej haus, txuj lom, cov kua txi txiv thiab lwm liaj teb li kua.
5. Feem ntau nws siv los ua cov kuab tshuaj nyob hauv chaw soj nstuam thiab kev tsim khoom.
