Polyether Polyols e entsoe ka ho arabela organic oxide le glycol.

Organic oxide e ka sehloohong e sebelisoang ke Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.

Li-glycol tse ka sehloohong tse sebelisoang ke Ethylene Glycol, Propylene Glycol, Metsi, Glycerine, Sorbitol, Sucrose, THME.

Polyols e na le lihlopha tsa "hydroxyl" (OH) tse sebetsang le lihlopha tsa isocyanate (NCO) ho li-isocyanate ho etsa polyurethanes.

Ho na le mefuta e mengata ea polyether polyols bakeng sa polyurethane.Lisebelisoa tsa PU tse nang le ts'ebetso e fapaneng li ka fumanoa ka karabelo lipakeng tsa li-initiator tse fapaneng le polymerization ea olefin.

Ka ho fetola lisebelisoa tse tala tsa PU kapa ho fetola li-catalyst, ts'ebetso ea polyether e ka fetoloa.Baqapi bana ba kenyelletsa joala ba diethyl, joala ba ternary, tetrahydrofuran, le polyether polyols e nkhang hamonate, joalo-joalo.

SEBELISA

Tšebeliso ea polyether e sebelisoang ho PU e feta 80%.Polyether polyurethane e ka aroloa

Polyether Polyol (PPG),

Polymeric Polyol (POP),

Polytetramethylene ether glycol (PTMEG, eo hape e bitsoang polytetrahydrofuran polyol) ho ea ka moqapi.

Li-polyether polyols li sebelisoa haholo ho foam e thata ea PU, foam e bonolo, le lihlahisoa tsa foam tse bopang.

Phatlalatso: Tse ling tsa litaba/litšoantšo sengolong sena li tsoa Marang-rang, 'me mohloli o se o boletsoe.Li sebelisoa feela ho bontša lintlha kapa maikutlo a boletsoeng sehloohong sena.Li etselitsoe feela puisano le ho ithuta, 'me ha li molemong oa khoebo.Haeba ho na le tlolo ea molao, ka kopo ikopanye le rona ho hlakola hanghang.
