I-1,2-Propylene Glycol CAS NO.57-55-6
IiNkcazo zeeMveliso
- I-1,2 i-Propylene glycol iphakathi kwe-bactericide difenoconazole kunye nemathiriyeli ekrwada ebalulekileyo ye-polyester engaxutywanga, i-epoxy resin, kunye ne-polyurethane resin. Isixa kulo mba malunga ne-45% yokusetyenziswa okupheleleyo kwe-1,2 propylene glycol. Le poly Ester engaxutywanga isetyenziswa ngokubanzi kwiingubo zomphezulu kunye neeplastiki ezomeleziweyo. I-1,2 I-Propylene glycol ine-viscosity enhle kunye ne-hygroscopicity, kwaye ayinayo ityhefu, ngoko isetyenziswa ngokubanzi njengento yokufunxa umswakama, i-antifreeze, i-lubricant kunye ne-solvent kwi-industry yokutya, iyeza kunye ne-cosmetic. Kwishishini lokutya, isetyenziswa ikakhulu njenge-emulsifier yokutya; kwangaxeshanye sisinyibilikisi esigqwesileyo se-seasonings kunye ne-pigments.
- Inkqubo yokutsalwa kwe-1,2 yepropylene glycol yeyobuchwephesha bokuhlukana kweekhemikhali. Le nkqubo isebenzisa iimpawu ukuba iityuwa ze-asidi ye-mineral zilula ukukhazimla, ngelixa iityuwa ze-asidi ze-organic kwi-propylene glycol fermentation broth akulula ukuba zikhazimle. Isixa esifanelekileyo se-asidi ye-inorganic yongezwa kwi-propylene glycol fermentation broth ukuze ithathe indawo yeetyuwa ze-organic acid kwi-broth fermentation kunye ne-organic acids. Ityuwa ye-mineral acid ehambelana nayo yenziwe; i-broth fermentation igxininiswe, ukwenzela ukuba ityuwa ye-mineral acid icwecwe, kwaye ihlukaniswe nomhluzi wokuvumba; umhluzi ogxininisiweyo wokuvutshelwa uba yipropylene glycol, i-succinic acid, i-lactic acid, i-acetic acid, i-glycerol kunye ne-2,3-butane Umxube wotywala, i-vacuum distillation yomxube wokufumana iimveliso zecandelo ngalinye. Kumashishini amayeza, ipropylene glycol isoloko isetyenziselwa ukunyibilikisa, ukuthambisa kunye ne-excipient ekwenzeni iintlobo zamafutha kunye namafutha. Ngenxa yokuhambelana kwayo kakuhle kunye neziqholo ezahlukahlukeneyo, iphinda isetyenziswe njenge-solvent kunye ne-softener ye-cosmetics.Propylene glycol iphinda isetyenziswe njenge-moisturizer yecuba, i-antifungal agent, izixhobo zokulungisa ukutya zokuthambisa ioli kunye nokutya kokumakishwa kwe-inki yokucoca. Isisombululo esinamanzi sepropylene glycol yi-antifreeze esebenzayo.

Isicelo
- Njenge-solvent, inokunyibilikisa izongezo zokutya ezinganyibilikiyo emanzini njengezigcini, ii-pigments, i-antioxidants, njl., kwaye emva koko yongeza ekutyeni; ine-hygroscopicity eyomeleleyo, kwaye inefuthe lokufuma kunye ne-anti-freezing kukutya.
- Njengomthwali weziyobisi kunye ne-arhente yeziyobisi yegranular. Ingasetyenziswa njenge humectant, softener, solvent, njl.
- Kwishishini lecuba, linokusetyenziswa njengencasa yecuba, icuba yokuthambisa, isigcinakaliso, njl.
- Kumzi-mveliso wokutya, isetyenziswa njengenyibilikisi yeencasa, umbala wokutya, izithambiso zokupakisha ukutya, kunye neearhente zokuchasa ukuncamathela.
