Khoom siv:
1.Ethanol yog ib qho tseem ceeb ntawm cov organic hnyav, dav siv hauv tshuaj, xim, khoom siv tu cev, tshuaj pleev ib ce, roj thiab roj thiab lwm txoj hauv kev, suav txog li 50% ntawm tag nrho cov khoom siv ethanol. Ethanol yog ib qho tseem ceeb ntawm cov khoom siv raw khoom, siv rau hauv kev tsim cov acetaldehyde, ethylene diene, ethylamine, ethyl acetate, acetic acid, chloroethane, thiab lwm yam, thiab muab tau los ntawm ntau yam intermediates ntawm kws tshuaj, dyes, xim, spices, hluavtaws roj hmab, detergents. , tshuaj tua kab, thiab lwm yam, nrog ntau tshaj 300 hom khoom, tab sis tam sim no kev siv ethanol ua cov khoom siv tshuaj nruab nrab yog maj mam poob qis, thiab ntau yam khoom, xws li acetaldehyde, acetic acid, ethyl cawv, tsis tau siv ethanol li cov khoom siv ntxiv lawm. raw khoom, tab sis ethyl cawv ua raw khoom. Txawm li cas los xij, kev siv ethanol ua cov tshuaj nruab nrab yog maj mam poob qis, thiab ntau yam khoom xws li acetaldehyde, acetic acid, ethyl cawv tsis siv ethanol ua raw khoom, tab sis hloov los ntawm lwm cov ntaub ntawv raw. Tshwj xeeb refined ethanol kuj tseem siv rau hauv kev tsim cov dej haus. Zoo ib yam li methanol, ethanol tuaj yeem siv los ua lub zog. Qee lub tebchaws tau pib siv ethanol ib leeg los ua roj tsheb lossis sib xyaw rau hauv roj av (10% lossis ntau dua) kom txuag tau roj av.
2.Siv los ua cov kuab tshuaj rau cov tshuaj nplaum, nitro sprays, varnishes, tshuaj pleev ib ce, inks, xim strippers, thiab lwm yam, nrog rau cov khoom siv raw rau kev tsim tshuaj tua kab, tshuaj, roj hmab, yas, hluavtaws fibers, detergents, thiab lwm yam. , thiab raws li antifreeze, roj, tshuaj tua kab mob thiab lwm yam. Hauv kev lag luam microelectronics, siv los ua tus dewatering thiab decontamination tus neeg sawv cev, tuaj yeem siv ua ke nrog tus neeg degreasing.
3.Siv raws li analytical reagent, xws li hnyav. Kuj tseem siv tau hauv kev lag luam kws tshuaj.
4.Siv hauv kev lag luam hluav taws xob, siv los ua dewatering thiab decontamination tus neeg saib xyuas thiab cov khoom xyaw degreasing.
5.Siv los yaj ib co insoluble electroplating organic additives, kuj siv raws li hexavalent chromium txo tus neeg sawv cev nyob rau hauv analytical chemistry.
6.Siv hauv kev lag luam cawv, organic synthesis, tshuaj tua kab mob thiab ua kuab tshuaj.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
3.Qhov kub cia yuav tsum tsis pub tshaj 37 ° C.
4. Khaws lub thawv kaw.
5.Nws yuav tsum tau muab cais los ntawm oxidants, acids, alkali hlau, amines, thiab lwm yam., tsis txhob sib tov cia.
6.Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab cov chaw ua pa.
7. Txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov pob zeb.
8.Qhov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
