Propylene glycol imagwiritsidwa ntchito ngati ma glycols ena.
Propylene glycol ndi chinthu chofunikira chopangira poliyesitala wosaturated, epoxy resin, ndi utomoni wa polyurethane.Ndalama zomwe zimagwiritsidwa ntchito m'derali zimakhala pafupifupi 45% yazomwe zimagwiritsidwa ntchito pa propylene glycol.Polyester yosakanizidwa yotereyi imagwiritsidwa ntchito kwambiri popanga mapulasitiki olimbikitsidwa ndi zokutira pamwamba.Propylene glycol ndi yabwino kwambiri ku viscosity ndi hygroscopicity ndipo sipoizoni, motero imagwiritsidwa ntchito kwambiri ngati hygroscopic agent, antifreeze, lubricants ndi solvents muzakudya, mankhwala ndi zodzikongoletsera.M'makampani azakudya, propylene glycol imakhudzidwa ndi mafuta acid kuti apereke propylene ester yamafuta acids, ndipo amagwiritsidwa ntchito makamaka ngati emulsifier ya chakudya;Propylene glycol ndi yabwino kusungunulira zokometsera ndi inki.Propylene glycol imagwiritsidwa ntchito ngati zosungunulira, zofewa komanso zowonjezera, ndi zina zambiri m'makampani opanga mankhwala popanga mitundu yosiyanasiyana yamafuta ndi ma salves.Propylene glycol imagwiritsidwanso ntchito ngati zosungunulira komanso zofewa zodzikongoletsera chifukwa imakhala yabwino kusungunuka ndi zonunkhira zosiyanasiyana.Propylene glycol imagwiritsidwanso ntchito ngati zonyowetsa fodya, antifungal agents, mafuta opangira chakudya ndi zosungunulira za inki yolembera chakudya.Aqueous solution ya propylene glycol ndi anti-freeze agent.
Pafupi ndi madzi, propylene glycol ndiye galimoto yonyamula chinyezi yomwe imagwiritsidwa ntchito popanga zodzikongoletsera.Imakhala ndi kutsekemera kwapakhungu kuposa glycerin, komanso imapereka kumva kosangalatsa ndi mafuta ochepa kuposa glycerin.Propylene glycol imagwiritsidwa ntchito ngati humectant chifukwa imatenga madzi kuchokera mumlengalenga.Imagwiranso ntchito ngati zosungunulira za anti-oxidants ndi zoteteza.Kuphatikiza apo, imakhala ndi zoteteza motsutsana ndi mabakiteriya ndi bowa zikagwiritsidwa ntchito mozungulira 16 peresenti kapena kupitilira apo.Pali nkhawa kuti propylene glycol imakwiyitsa kwambiri, ngakhale ikuwoneka kuti ndiyotetezeka pakagwiritsidwe ntchito pansi pa 5 peresenti.
Propylene Glycol ndi chosungunulira cha humectant komanso kukoma komwe ndi mowa wa polyhydric (polyol).ndi madzi owoneka bwino, owoneka bwino komanso osungunuka kwathunthu m'madzi pa 20 ° C komanso kusungunuka kwamafuta abwino.imagwira ntchito ngati humectant, monga glycerol ndi sorbitol, posunga chinyezi chomwe chimafunidwa komanso kapangidwe kake muzakudya monga kokonati wophwanyidwa ndi ma icings.zimagwira ntchito ngati zosungunulira zokometsera ndi mitundu yomwe ili yosasungunuka m'madzi.amagwiritsidwanso ntchito muzakumwa ndi maswiti.
