Polyether Polyols ikorwa mugukora okiside kama na glycol.

Okiside nyamukuru ikoreshwa ni Ethylene Oxide, Oxide ya Propylene, Oxide Butylene, Epichlorohydrin.

Glycol nyamukuru ikoreshwa ni Ethylene Glycol, Propylene Glycol, Amazi, Glycerine, Sorbitol, Sucrose, THME.

Polyol irimo amatsinda ya hydroxyl (OH) yitwara neza hamwe nitsinda rya isocyanate (NCO) kuri isocyanates kugirango ikore polyurethanes.

Hariho ubwoko bwinshi bwa polyether polyole kuri polyurethane.Ibikoresho bya PU nibikorwa bitandukanye birashobora kuboneka hamwe nigisubizo hagati yabatangije batandukanye na olefin polymerisation.

Muguhindura ibikoresho fatizo bya PU cyangwa guhindura catalizator, imikorere ya polyether irashobora guhinduka.Muri aba batangizanya harimo inzoga ya diethyl, inzoga za ternary, tetrahydrofuran, hamwe na poliol aromatic polyether, nibindi.

UKORESHE

Imikoreshereze ya polyether ikoreshwa muri PU irenga 80%.Polyurethane irashobora gushyirwa mubikorwa

Polyoly Polyol (PPG),

Polymeric Polyol (POP),

Polytetramethylene ether glycol (PTMEG, nanone yitwa polytetrahydrofuran polyol) nkuko byatangijwe na nyirubwite.

Polyol polyoly ikoreshwa cyane cyane muri PU igoye cyane, ifuro yoroshye, hamwe nibicuruzwa bibumba.

Itangazo ： Bimwe mubirimo / amashusho muriki kiganiro biva kuri interineti, kandi inkomoko yagaragaye.Byakoreshejwe gusa kwerekana ukuri cyangwa ibitekerezo bivugwa muriyi ngingo.Zigenewe gusa itumanaho no kwiga, kandi ntabwo ari izindi mpamvu zubucuruzi.Niba hari ihohoterwa, nyamuneka twandikire kugirango dusibe ako kanya.
