Nyob rau hauv lub ntiaj teb niaj hnub no, qhov kev siv tshuaj muaj ntau ntxiv nyob rau hauv peb lub neej txhua hnub, to taub cov khoom siv thiab kev cuam tshuam ntawm cov tshuaj no tseem ceeb heev. Tshwj xeeb, cov lus nug ntawm seb ib qho tuaj yeem sib tov isopropanol thiab acetone muaj qhov tshwm sim tseem ceeb hauv ntau daim ntawv thov. Hauv tsab xov xwm no, peb yuav delve rau hauv cov tshuaj muaj tshuaj ntawm ob yam tshuaj, tshawb txog lawv cov kev sib cuam tshuam, thiab tham txog qhov ua tau zoo ntawm lawv.

IsoPropanol, tseem hu ua 2-propanol, yog ib qho tsis muaj kob, cov kua ua kua nrog cov xeeb ceem tsw. Nws yog miscible nrog dej thiab soluble nyob rau hauv ntau cov emvents organic. IsoPropanol yog feem ntau siv los ua cov kuab tshuaj, kev tu tus neeg saib xyuas, thiab hauv kev tsim ntau yam tshuaj lom. Acetone, ntawm qhov tod tes, yog dav siv cov kuab tshuaj muaj zog uas tseem siv los ua tus ntsia thawv txhuam Picish Remover. Nws yog cov muaj zog heev thiab ua kom muaj zog nrog ntau cov kuab tshuaj organic.

Thaum isopropanol thiab acetone tau sib xyaw, lawv tsim kev sib xyaw binary. Cov kev sib cuam tshuam ntawm ob qho tshuaj yog qhov tsawg dua li lawv tsis yauv mus ua cov tshuaj lom neeg los tsim cov khoom siv tshiab. Hloov chaw, lawv tseem nyob nrog cais cov chaw hauv ib theem. Cov cuab yeej no yog ntaus nqi rau lawv cov polarities thiab hydrogen-tsev muaj peev xwm.

Cov kev sib xyaw ntawm isopropanol thiab acetone muaj ntau daim ntawv thov siv. Piv txwv li, hauv kev tsim cov nplaum thiab cov tshuaj yeeb yaj kiab, cov tshuaj no feem ntau siv hauv kev sib xyaw ua ke los tsim cov nplaum uas xav tau lossis cov khoom ntiag tug. Cov kev sib xyaw ua tau tseem siv tau hauv kev tu huv si tsim cov kuab tshuaj sib xyaw nrog cov haujlwm tshwj xeeb rau kev sib cav sib txawv.

Txawm li cas los xij, thaum nws sib xyaw isopropanol thiab acetone tuaj yeem tsim cov khoom muaj txiaj ntsig, nws yog qhov tseem ceeb kom ua kev ceev faj thaum cov txheej txheem. Isopropanol thiab acetone muaj cov ntsiab lus flash tsawg, ua rau lawv muaj hluav taws kub heev thaum sib xyaw nrog huab cua. Yog li no, ib qho yuav tsum xyuas kom ua kom muaj cua zoo thiab siv kev ceev faj thaum tuav cov tshuaj no kom tsis txhob muaj hluav taws lossis tawg.

Hauv kev xaus, sib xyaw isopropanol thiab acetone tsis ua rau cov tshuaj lom neeg ntawm ob qho tshuaj. Hloov chaw, lawv tsim kev sib xyaw binary uas tswj hwm lawv cov khoom qub. Qhov kev sib xyaw no muaj ntau cov ntawv thov hauv ntau yam lag luam, suav nrog kev ntxuav, cov nplaum tsim, thiab lwm yam. Txawm li cas los xij, vim lawv cov hniav khaus, ceev faj yuav tsum tau ua thaum tuav cov tshuaj no kom tsis txhob muaj hluav taws lossis tawg.
