Iipolyether zePolyolszenziwe ngokusabela i-organic oxide kunye ne-glycol.

I-organic oxide engundoqo esetyenziswayoEthylene oxide,Ipropylene oxide,I-Butylene oxide,Epichlorohydrin.

Iiglycols eziphambili ezisetyenziswayoEthylene Glycol,Ipropylene Glycol,Amanzi,IGlycerine,ISorbitol,Sucrose,THME.

IiPolyols ziqulathe amaqela asebenzayo ehydroxyl (OH) athi asebenze kunye namaqela e-isocyanate (NCO) kwi-isocyanates ukwenza iipolyurethanes.

Kukho iintlobo ezininzi zeepolyether polyolsi-polyurethane.Izinto ze-PU ezinomsebenzi ohlukeneyo zinokufunyanwa ngokusabela phakathi kwabaqalisi abahlukeneyo kunye ne-olefin polymerization.

Ngokuguqula izinto eziluhlaza ze-PU okanye ukutshintsha i-catalyst, ukusebenza kwe-polyether kunokuguqulwa.Aba baqalisi babandakanya utywala be-diethyl, utywala be-ternary, i-tetrahydrofuran, kunye ne-aromatics polyether polyols, njl.

Isibhengezo:Eminye imixholo ivela kwi-Intanethi, kwaye umthombo uye waphawulwa.Zisetyenziselwa kuphela ukubonisa izibakala okanye izimvo ezichazwe kweli nqaku.Zezonxibelelwano kunye nokufunda kuphela, kwaye azikho ezinye iinjongo zorhwebo.Ukuba kukho naluphi na ulwaphulo, nceda uqhagamshelane nathi ukuze ucime ngokukhawuleza.
