Cov lus qhia ntxaws ntxaws
Diethyleneglycol dag, tseem hu ua DEG txaus siab lossis DMEG, yog cov organic sib xyaw nrog cov mis (hoch₂CH₂O)₂HCoo. Nws yog cov kua ntshiab, tsis muaj kob uas muaj ntxhiab tsw me ntsis.
Qee qhov khoom tseem ceeb thiab cov yam ntxwv ntawm diethyleneglycol ua haujlwm muaj xws li:
Solubility:Deg txaus siab yog soluble hauv dej thiab polar solvents zoo li ethanol thiab acetone. Nws muaj tsawg solubility hauv cov kuab tshuaj tsis ncaj.
Stability:Qhov no sib xyaw no yog qhov ruaj khov nyob rau hauv ib txwm muaj. Nws tsis decompose lossis degrade yooj yim.
Boiling taw tes:Diethyleneglycol dlormate muaj qhov cub npau npau ntawm 245°C (473°F).
Kev Nyab Xeeb:Deg txaus siab yog feem ntau suav tias yuav muaj kev nyab xeeb thaum siv thiab siv tes tsim nyog. Txawm li cas los xij, zoo li kev tshuaj lom neeg, nws yuav tsum ua kom zoo, thiab kev ceev faj kev nyab xeeb yuav tsum tau ua raws.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov lus qhia no tau muab cov ntsiab lus dav dav ntawm Diethyleneglycol ua haujlwm thiab nws cov ntawv thov. Rau cov ntsiab lus tshwj xeeb thiab cov ntaub ntawv hais txog nws siv hauv ib qho ntsiab lus teb lossis kev lag luam, nws raug nquahu los tham cov peev txheej lossis cov kws tshaj lij.
Daim ntawv thov
Diethylene Glycolol didesormate (DMEG) muaj ob peb daim ntawv thov hla ntau yam lag luam. Nov yog qee qhov ntawm nws cov kev siv:
Kuab:DMEG feem ntau siv los ua cov kuab tshuaj rau ntau cov ntaub ntawv, suav nrog cov resins, tsho xim, thiab zas. Nws lub siab npau npau thiab tsis muaj lub tshuab hluav taws xob ua rau nws haum rau cov tshuaj sib txawv thiab tawg cov tshuaj sib txawv.
Tshuaj Nruab Nrab Nruab Nrab:DMEG tuaj yeem ua raws li kev lom neeg nruab nrab hauv ntau cov txheej txheem synthesis. Nws tuaj yeem siv los ua cov khoom siv raw rau kev tsim lwm cov tshuaj lom neeg zoo li Esters, cov tshuab yas, thiab kws tshuaj nruab nrab.
Kev tu thiab degreasing tus neeg sawv cev:DMEG muaj txiaj ntsig hauv kev tshem cov roj, roj, thiab lwm yam paug los ntawm cov chaw. Nws tuaj yeem siv los ua tus neeg saib xyuas tu hauv kev siv cov kev siv hlau, cov khoom siv daws teeb meem hluav taws xob, thiab siv hluav taws xob.
Adhesive thiab Sealant Kev Lag Luam:DMEG tuaj yeem siv tau raws li cov kuab tshuaj lossis ua rau muaj kev ua kom zoo nkauj ntawm cov nplaum thiab cov kab xev. Nws pab hauv kev ua tiav qhov xav tau viscosity thiab txhim kho daim ntawv thov thiab kom qhuav cov yam ntxwv ntawm cov khoom kawg.
Textile kev lag luam:DMEG yog siv los ua cov kuab tshuaj nyob rau hauv Dyeing thiab luam ntawv ntawm textiles. Nws pab nyob rau hauv dissolving kawg thiab txhim kho xim dawb.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov ntawv thov tshwj xeeb ntawm DMEG tuaj yeem sib txawv nyob ntawm kev lag luam thiab siv. Cov ntaub ntawv tsim khoom thiab cov neeg siv DMEG yuav tsum tau sab laj cov ntaub ntawv kev nyab xeeb (SDS) thiab ua raws li cov lus qhia thiab ua raws li kev tuav thiab siv.
