Za Propylene Glycol
Propylene glycol (dzina la IUPAC: propane-1,2-diol) ndi mankhwala amadzimadzi opanda mtundu komanso opanda fungo omwe amagwiritsidwa ntchito kwa zaka zambiri.Propylene glycol ndi chinthu chosavuta chomwe chili ndi mankhwala C3H8O2.Imasakanikirana ndi mitundu yambiri ya zosungunulira, kuphatikiza madzi, acetone, ndi chloroform.
Chemical Applications
Propylene glycol ingagwiritsidwe ntchito m'mafakitale osiyanasiyana ndipo tsatanetsatane ndi motere.
Propylene glycol ndi chinthu chofunika kwambiri cha poliyesitala wosaturated, epoxy resin ndi polyurethane resin, zomwe zimapanga pafupifupi 45% ya mankhwala onse a propylene glycol.Polyester wopanda unsaturated uyu amagwiritsidwa ntchito kwambiri pakuyala pamwamba ndi mapulasitiki olimbikitsidwa.
Propylene glycol imakhudzidwa ndi mafuta acid kupanga propylene glycol fatty acid ester, yomwe imagwiritsidwa ntchito kwambiri ngati emulsifier yazakudya m'makampani azakudya komanso ndi chosungunulira chabwino kwambiri cha zokometsera ndi utoto.
Propylene glycol nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira, zofewa komanso zothandiza popanga mafuta odzola osiyanasiyana m'makampani opanga mankhwala.Ndi chifukwa chakuti propylene glycol ndi mitundu yonse ya zonunkhira zimakhala ndi kusungunuka kwabwino.
Propylene glycol imagwiritsidwanso ntchito ngati chinyezi cha fodya, antiseptic, lubricant pazida zopangira chakudya komanso zosungunulira za inki zolembera chakudya.
The propylene glycol solution ndi antifreeze yogwira mtima.
