Polyether Polyolswaxaa lagu sameeyaa iyadoo la falcelinayo oxide organic iyo glycol.
Oksaydhka dabiiciga ah ee ugu weyn ee la isticmaalo waaEthylene oxide,Propylene oxide,Butylene oxide,Epichlorohydrin.
Glycols-ka ugu weyn ee la isticmaalo waaEthylene Glycol,Propylene Glycol,Biyo,Glycerin,Sorbitol,Sucrose,THME
Polyols waxay ka kooban yihiin kooxaha reactive hydroxyl (OH) kuwaas oo la falgala kooxaha isocyanate (NCO) ee isocyanates si ay u sameeyaan polyurethane.
Waxaa jira noocyo badan oo polyeter polyols ah oo loogu talagalaypolyurethane.Qalabka PU ee leh waxqabadyo kala duwan ayaa lagu heli karaa falcelinta u dhaxaysa bilawga kala duwan iyo olefin polymerization.
Adiga oo wax ka beddelaya alaabta ceeriin ee PU ama beddelidda kicinta, waxqabadka polyeter-ka waa la beddeli karaa.Bilaabayaashan waxaa ka mid ah aalkolada diethyl, khamriga ternary, tetrahydrofuran, iyo polyeter polyeter aromatic, iwm.
Baaq: Qaar ka mid ah waxa ku jira waxay ka yimaaddaan internetka, ishana waa la xusay.Waxa kaliya oo loo isticmaalaa in lagu muujiyo xaqiiqooyinka ama fikradaha lagu sheegay maqaalkan.Waxay kaliya u yihiin isgaarsiin iyo waxbarasho, mana aha ujeeddooyin kale oo ganacsi.
