Dipropylene Glycol Dimethyl Ether nrog CAS 111109-77-4
Dipropylene Glycol Dimethyl Ether luv luv as DPGDME, nrog rau tus lej cas 111109-77-4, yog ib qho tshuaj polar aprotic uas siv ntau. Dpdme solvent muaj qhov nruab nrab polarity, yooj yim soluble hauv dej, thiab tuaj yeem sib xyaw nrog feem ntau cov organic solvents. Dipropylene glycol dimethyl ether yog ib qho tshuaj zoo heev "water-organic phase". Dpdme solvent yog ib qho tshuaj nruab nrab-boiling-point, tsis kub hnyiab tab sis yuav tsum khaws cia kom deb ntawm cov nplaim taws kub.
Dipropylene glycol dimethyl ether yog ib qho tshuaj uas siv tau ntau yam thiab tsis ua rau ib puag ncig puas tsuaj, muaj ntxhiab tsw qab, ua rau lub cev yaj sai, ruaj khov, yaj tau zoo thiab muaj kev nyab xeeb rau tib neeg txoj kev noj qab haus huv. Tebchaws Meskas thiab European Union tau teev tseg ua cov tshuaj ntsuab uas tsis yog HAP/NAP (tsis muaj kev phom sij hauv daim ntawv teev cov pa phem). Dipropylene glycol dimethyl ether 99.0 feem ntau siv tau rau hauv cov txheej txheem dej thiab cov txheej txheem kho.

Dipropylene glycol dimethyl ether yog siv dav hauv ntau yam kev lag luam thiab kev tshawb fawb vim nws cov yam ntxwv ntawm "tsis muaj tshuaj lom, solubility siab thiab tsis tshua muaj volatility":
Kev lag luam coatings thiab inks:Dipropylene glycol dimethyl ether, ua cov kuab tshuaj lossis cov tshuaj sib xyaw, yog siv rau hauv cov txheej txheem dej, cov txheej txheem kuab tshuaj thiab cov kua mem. Nws tuaj yeem txhim kho qhov solubility ntawm cov resins (xws li acrylic resins thiab polyurethane resins), txhim kho qhov sib npaug thiab kev nplaum ntawm cov txheej txheem, thiab tib lub sijhawm txo qhov kev tso tawm ntawm cov organic compounds (VOCs).
Cov tshuaj ntxuav thiab cov tshuaj degreasing:Vim lawv muaj cov yam ntxwv hydrophilic thiab lipophilic, lawv siv tau rau hauv cov "dej-based cleaning agent" rau cov khoom siv hluav taws xob thiab cov cuab yeej precision. Lawv tuaj yeem tshem tawm cov roj stains thiab cov flux residues (flux residues), thiab tsis ua rau cov khoom siv tseem ceeb (xws li hlau thiab yas) xeb.
Hauv kev kho mob thiab tshuaj tua kab:Dpdme solvent, ua ib qho "solvent/co-solvent" rau cov khoom xyaw nquag ntawm cov tshuaj lossis tshuaj tua kab, yog siv rau hauv kev npaj cov kua dej hauv qhov ncauj thiab cov tshuaj tua kab emulsifiable concentrate. Dipropylene glycol dimethyl ether tuaj yeem txhim kho qhov solubility thiab kev ruaj khov ntawm cov khoom xyaw nquag thaum txo qhov khaus rau tib neeg lub cev lossis cov qoob loo.
Kev tsim tshuaj lom neeg thiab cov tshuaj tiv thaiv:Dipropylene glycol dimethyl ether, ua cov kuab tshuaj polar aprotic, tuaj yeem hloov cov kuab tshuaj lom neeg ib txwm muaj thiab siv rau hauv cov tshuaj tiv thaiv organic synthesis (xws li nucleophilic substitution thiab catalytic reactions), uas tuaj yeem ua rau kom muaj kev cuam tshuam thiab cov khoom tsim tawm.
Kev saib xyuas tus kheej thiab cov khoom siv tshuaj txhua hnub:Dipropylene glycol dimethyl ether siv me me hauv cov khoom siv tu tawv nqaij thiab cov tshuaj pleev ib ce (xws li cov tshuaj pleev ntsej muag thiab cov tshuaj tsw qab) ua cov kuab tshuaj lossis cov tshuaj moisturizer, pab yaj cov khoom xyaw uas yaj hauv roj (xws li vitamin E), thaum txhim kho kev xav ntawm daim tawv nqaij thiab kev ruaj khov ntawm cov khoom.
