Triethylene Glycol Butyl Ether

Cov tshuaj ua haujlwm zoo thiab zoo rau ib puag ncig, ua rau muaj kev txhim kho zoo hauv ntau yam lag luam

Diethylene Glycol Butyl Ether (lub npe tshuaj: Diethylene Glycol Monobutyl Ether, lub npe lus Askiv: Diethylene Glycol Butyl Ether, luv ua DGBE) yog cov tshuaj organic ntau yam nrog lub zog yaj zoo, ruaj khov zoo heev, thiab kev nyab xeeb ib puag ncig. Nrog nws cov yam ntxwv tseem ceeb ntawm qhov kub siab, qhov tsis tshua muaj volatility, thiab solubility hauv dej thiab roj, nrog rau cov txiaj ntsig ntsuab ntawm kev lom tsawg thiab VOC emissions qis, DGBE tau dhau los ua cov khoom siv tseem ceeb hauv ntau qhov chaw xws li coatings, inks, kev ntxuav kev lag luam, hluav taws xob, thiab tshuaj. Nws tuaj yeem hloov cov tshuaj kuab paug ib txwm muaj, pab cov lag luam ua tiav ntau lub hom phiaj ntawm kev ua kom zoo dua qub, kev txhim kho kev ua haujlwm, thiab kev ua raws li kev cai.

Kev Ua Tau Zoo Tseem Ceeb: Cov txiaj ntsig ntau yam, txhais tau tias yog tus qauv tshiab rau kev ua tau zoo ntawm cov kuab tshuaj

1. Kub siab thiab tsis tshua muaj kev hloov pauv, ua rau kev tsim kho thiab kev tsim khoom ruaj khov dua

DGBE muaj lub ntsiab lus kub txog li 230 ° C thiab lub khob kaw lub teeb ci ntawm 78 ° C, nrog rau qhov qeeb thiab sib npaug ntawm cov dej noo. Hauv cov xwm txheej xws li kev tsim kho kub siab thiab kev ci ntev, nws tuaj yeem kho qhov ceev ntawm lub kaw lus kom qhuav, zam cov qhov tsis zoo xws li tev txiv kab ntxwv, qhov, thiab ua kom dawb ntawm cov zaj duab xis txheej los ntawm kev ua kom sai ntawm cov kuab tshuaj. Tib lub sijhawm, qhov tsim qauv siab ntawm qhov teeb ci txo ​​​​cov kev pheej hmoo kev nyab xeeb thaum lub sijhawm tsim khoom thiab khaws cia, hloov kho rau ntau yam kev xav tau kev lag luam loj.

2. Lub zog yaj dav dav, muaj zog hloov pauv tau rau ob qho dej thiab roj

Nws muaj cov khoom zoo heev (ob qho tib si hydrophilic thiab lipophilic), thiab tuaj yeem yaj ntau yam tshuaj xws li cov resins (acrylic resin, epoxy resin, alkyd resin, thiab lwm yam), nitrocellulose, roj, dyes, thiab cov roj av. Nws tuaj yeem sib xyaw nrog dej hauv txhua qhov sib piv thiab sib xws nrog cov organic solvents xws li ethanol, acetone, thiab toluene. Nws tuaj yeem hloov kho ncaj qha yam tsis muaj kev hloov kho tseem ceeb rau cov mis uas twb muaj lawm, txo cov nqi ntawm kev hloov kho mis lag luam.

3. Ntsuab, muaj kev nyab xeeb, thiab ua raws li txoj cai, ua raws li qhov sib txawv ntawm kev tiv thaiv ib puag ncig

Tsim los ntawm kev siv cov txheej txheem tsim cov tshuaj ntsuab catalytic, cov khoom muaj qhov huv ntawm ≥99.5% thiab cov ntsiab lus tsis muaj kuab paug tsawg heev. Nws muaj qhov lom me ntsis, nrog rau kev lom txo qis ntau dua 75% piv rau cov kuab tshuaj ib txwm muaj (xws li ethylene glycol ethers) thiab VOC emissions txo qis 90%. Nws tuaj yeem ua tau raws li cov cai ib puag ncig hauv tsev thiab txawv teb chaws xws li GB, REACH, thiab TSCA, pab cov tuam txhab lag luam hla dhau cov teeb meem kev lag luam ntsuab.

4. Kev ua tau zoo heev ntawm kev sib txuas, txhim kho kev ruaj ntseg ntawm lub cev

Nws muaj kev sib txuas zoo thiab kev ruaj khov, uas tuaj yeem txhim kho qhov sib xws ntawm cov kab ke sib xyaw, tiv thaiv kev faib cov mis thiab nag, thiab ntev lub sijhawm khaws cia khoom. Thaum ntxiv rau cov khoom xws li cov neeg sawv cev ntxuav thiab cov tshuaj pleev xim, nws tuaj yeem txhim kho lub peev xwm tshem tawm cov pa phem, zoo ntawm zaj duab xis, thiab tiv thaiv huab cua ntawm lub kaw lus, ua tiav kev ua tau zoo ntawm cov khoom.
