Igama Lomkhiqizo:i-polyether polyol

Ifomethi ye-Molecular:nC3H6O

Isakhiwo samangqamuzana omkhiqizo:

Chemical Properties:

Ama-polyether polyols ayizici ezibalulekile ezisetshenziswa ekukhiqizeni ama-polyurethanes.

Ama-polyurethane asekelwe ku-polyether abonisa ukuzinza kwe-hydrolytic okuthuthukisiwe kanye nokumelana okuhle kakhulu nama-asidi abuthakathaka nezisekelo uma kuqhathaniswa nama-polyester-based polyurethanes.

I-polyether polyurethane ingahlukaniswa ibe i-polyether yegwebu elithambile, i-polyether eyigwebu eqinile kanye ne-elastomer ene-polyether ngokusho kokusebenza kwemikhiqizo ye-polyether.

Kodwa-ke, ama-polyether-based polyurethanes angenwa kalula emisebeni ye-UV futhi anikeze ukumelana okuphansi kumafutha namafutha uma kuqhathaniswa nama-polyester-based polyurethanes.

Isicelo:

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.
