Taw qhia
Dipropylene glycol. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm dipropylene glycol:
Zoo:
1. Cov tsos mob: Dipropylene glycol yog cov kua uas tsis muaj xim rau daj.
2. Tsis hnov tsw: muaj ib yam tsw tsw.
3. Solubility: Nws tuaj yeem ua rau miscible nrog dej thiab ntau yam organic solvents.
Siv:
Nws tuaj yeem siv los ua cov yas yas, emulsifier, thickener, antifreeze thiab lubricant, thiab lwm yam.
3. Kev siv hauv chav kuaj: Nws tuaj yeem siv los ua cov kuab tshuaj thiab cov tshuaj extractant rau cov tshuaj lom neeg thiab cov txheej txheem sib cais hauv chav kuaj.
Txoj kev:
Dipropylene glycol tuaj yeem tau txais los ntawm reacting dipropane nrog cov kua qaub catalyst. Hauv cov tshuaj tiv thaiv, monopropane tau txais cov tshuaj tiv thaiv hydrolysis los tsim monopropylene glycol.
Cov ntaub ntawv kev nyab xeeb:
1. Dipropylene glycol tej zaum yuav muaj teeb meem rau tib neeg lub cev los ntawm qhov ncauj, kev sib cuag ntawm daim tawv nqaij thiab nqus tau pa, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha.
2. Thaum siv dipropylene glycol, yuav tsum ua raws li cov txheej txheem kev khiav hauj lwm thiab kev nyab xeeb xws li hnav cov hnab looj tes tiv thaiv, tsom iav, thiab cov khoom tiv thaiv ua pa.
4. Thaum khaws cia thiab tuav cov dipropylene glycol, yuav tsum tau ua raws li cov txheej txheem kev ruaj ntseg thiab tuav kom tsis txhob muaj kev cuam tshuam tsis zoo nrog lwm cov tshuaj.
