Lebitso la Sehlahiswa:polyether polyol

Sebopeho sa molek'hule:nC3H6O

Sehlahisoa sebopeho sa molek'hule:

Lintho tsa Lik'hemik'hale:

Polyether polyols ke likarolo tsa bohlokoa tse sebelisoang tlhahisong ea polyurethanes.

Polyether-based polyurethanes e bonts'a botsitso bo matlafalitsoeng ba hydrolytic le khanyetso e ntle ho li-acid tse fokolang le metheo ha e bapisoa le polyurethanes e thehiloeng ho polyester.

Polyether polyurethane e ka aroloa ka polyether ea foam e bonolo, polyether ea foam e thata le elastomer e nang le polyether ho latela ts'ebetso ea lihlahisoa tsa polyether.

Leha ho le joalo, li-polyurethanes tse thehiloeng ho polyether li hlaseloa habonolo ke mahlaseli a UV 'me li fana ka khanyetso e fokolang ho oli le mafura ha li bapisoa le polyester-based polyurethanes.

Kopo:

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.

Polyether polyols e sebelisoa haholo ho foam e thata ea PU, foam e bonolo, le lihlahisoa tsa foam tse bopang.
