1,2-Propylene Glycol CAS NO.57-55-6
Kufotokozera Zamalonda
- 1,2 Propylene glycol wapakatikati wa bactericide difenoconazole ndi zofunika zopangira poliyesitala unsaturated, epoxy resin, ndi polyurethane utomoni. Ndalama zomwe zili m'mbali iyi zimakhala pafupifupi 45% ya 1,2 propylene glycol yomwe imamwa. Ester wosaturated wa poly Ester amagwiritsidwa ntchito kwambiri pakuyala pamwamba ndi mapulasitiki olimba. 1,2 Propylene glycol imakhala ndi kukhuthala kwabwino komanso hygroscopicity, ndipo ilibe poizoni, choncho imagwiritsidwa ntchito kwambiri ngati chinyezi, antifreeze, lubricant ndi zosungunulira m'mafakitale azakudya, mankhwala ndi zodzikongoletsera. M'makampani azakudya, amagwiritsidwa ntchito makamaka ngati emulsifier yazakudya; nthawi yomweyo ndi zosungunulira zabwino kwambiri zokometsera ndi inki.
- Njira yochotsera 1,2 propylene glycol ndi gawo laukadaulo wolekanitsa mankhwala. Izi zimagwiritsa ntchito mikhalidwe yomwe mchere wa mchere wa mchere umakhala wosavuta kuwunikira, pomwe mchere wa organic acid mu msuzi wa propylene glycol fermentation siwosavuta kuwunikira. Kuchuluka koyenera kwa asidi wopangidwa ndi zinthu zina zimawonjezedwa ku msuzi wa propylene glycol fermentation kuti m'malo mwa mchere wa organic acid mu msuzi wowotchera ndi ma organic acid. The lolingana mchere asidi mchere kwaiye; ndi nayonso mphamvu msuzi anaikira, kuti mchere asidi mchere crystallizes, ndipo analekanitsidwa nayo nayonso mphamvu msuzi; The anaikira nayonso mphamvu msuzi amakhala propylene glycol, succinic asidi, asidi lactic, asidi asidi, glycerol ndi 2,3-butane Kusakaniza mowa, zingalowe distillation wa osakaniza kupeza mankhwala a chigawo chilichonse. M'makampani opanga mankhwala, propylene glycol nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira, zofewa komanso zothandiza popanga mafuta ndi mafuta osiyanasiyana. Chifukwa chogwirizana bwino ndi zonunkhira zosiyanasiyana, amagwiritsidwanso ntchito ngati zosungunulira ndi zofewa za zodzoladzola.Propylene glycol imagwiritsidwanso ntchito ngati moisturizer ya fodya, antifungal agent, zida zopangira chakudya zopangira mafuta ndi chakudya cholembera inki chosungunulira. Njira yamadzimadzi ya propylene glycol ndi antifreeze yogwira mtima.

Kugwiritsa ntchito
- Monga zosungunulira, zimatha kusungunula zowonjezera zakudya zomwe sizisungunuka m'madzi monga zosungira, ma pigment, antioxidants, etc., kenaka kuwonjezera pa chakudya; imakhala ndi hygroscopicity yamphamvu, ndipo imakhala ndi zonyowa komanso zoletsa kuzizira pazakudya.
- Monga chonyamulira mankhwala ndi granular mankhwala wothandizira. Itha kugwiritsidwa ntchito ngati humectant, softener, solvent, etc.
- M'makampani a fodya, amatha kugwiritsidwa ntchito ngati kukoma kwa fodya, moisturizer ya fodya, preservative, etc.
- M'makampani azakudya, amagwiritsidwa ntchito ngati zosungunulira zokometsera, mitundu yazakudya, zofewa zopakira zakudya, komanso zotsutsana ndi zomata.
