Ama-Polyether Polyols enziwa ngokuphendula i-organic oxide ne-glycol.

I-organic oxide eyinhloko esetshenziswa i-Ethylene Oxide, i-Propylene Oxide, i-Butylene Oxide, i-Epichlorohydrin.

Ama-glycols amakhulu asetshenziswa i-Ethylene Glycol, i-Propylene Glycol, Amanzi, i-Glycerine, i-Sorbitol, i-Sucrose, i-THME.

Ama-Polyols aqukethe amaqembu e-hydroxyl (OH) asebenzayo ahlangana namaqembu e-isocyanate (NCO) kuma-isocyanate ukuze akhe ama-polyurethanes.

Kunezinhlobo eziningi ze-polyether polyols ye-polyurethane.Izinto ze-PU ezinokusebenza okuhlukile zingatholwa ngokusabela phakathi kwabaqalisi abahlukene kanye ne-olefin polymerization.

Ngokushintsha izinto zokusetshenziswa ze-PU noma ngokushintsha i-catalyst, ukusebenza kwe-polyether kungashintshwa.Laba baqalisi bahlanganisa i-diethyl alcohol, i-ternary alcohol, i-tetrahydrofuran, nama-polyether polyether anuka kamnandi, njll.

IYASEBENZISA

Ukusetshenziswa kwe-polyether esetshenziswa ku-PU kungaphezu kuka-80%.I-polyether polyurethane ingahlukaniswa

I-Polyether Polyol (PPG),

I-Polymeric Polyol (POP),

I-Polytetramethylene ether glycol (PTMEG, ebizwa nangokuthi i-polytetrahydrofuran polyol) ngokusho komqalisi.

Ama-polyether polyols asetshenziswa kakhulu ku-PU igwebu eliqinile, igwebu elithambile, kanye nemikhiqizo yegwebu lokubumba.

Isimemezelo:Okunye okuqukethwe/izithombe kulesi sihloko zivela ku-inthanethi, futhi umthombo uqashelwe.Zisetshenziselwa kuphela ukukhombisa amaqiniso noma imibono eshiwo kulesi sihloko.Ezokuxhumana nokufunda kuphela, futhi azizona ezinye izinjongo zentengiso.Uma kukhona ukwephulwa komthetho, sicela usithinte ukuze sikususe ngokushesha.
