Polyether Polyols: Lisebelisoa tse sebetsang hantle bakeng sa lits'ebetso tse fapaneng
Masimo a Maholo a Kopo
Ho di-sealant, ho hanyetsa metsi le dikhemikhale tsa polyether resin ho etsa hore e be thepa e ntle ya ho kwala. Di thibela metsi le dikhemikhale ho kena ka katleho mme di sebediswa haholo ho aha ho thibela metsi ho kena, ho kwala diphaephe le ho kenya disebediswa tsa elektroniki. Di-sealant tse thehilweng ho polyether resin le tsona di bontsha tshebetso e ntle mochesong o tlase, di boloka katleho ya ho kwala maemong a lehodimo a feteletseng.
Ho li-elastomer, li-resin tsa polyether li sebelisoa ho hlahisa li-elastomer tsa thermoplastic tse sebetsang hantle (TPEs). Lisebelisoa tsena li kopanya ho tenyetseha ha rabara le bonolo ba ho e lokisa ba polasetiki 'me li sebelisoa haholo lieta, linthong tsa ho bapala, lisebelisoa tsa bongaka le likarolo tsa likoloi. Ho tenyetseha le ho tšoarella ha li-resin tsa polyether ho li etsa khetho e ntle bakeng sa ho etsa li-elastomer tse sebetsang hantle.
Indastering ea lisebelisoa tsa elektroniki, khanyetso ea lik'hemik'hale ea li-resin tsa polyether le ho lumellana ha tsona ka lintho tse phelang li etsa hore li be ntle bakeng sa ho kenngoa ha li-elektronike le thepa ea ho thibela ho bola. Li sireletsa likarolo tsa elektroniki mongobong le mafomeng a lik'hemik'hale ha ka nako e ts'oanang li fana ka ho thibela ho bola hantle ha motlakase. Li-resin tsa polyether li boetse li sebelisoa tlhahisong ea li-photoresist le likhomaretsi tsa elektroniki, li fihlela litlhoko tse nepahetseng haholo tsa indasteri ea lisebelisoa tsa elektroniki.
Lefapheng la bongaka, ho lumellana ha liresine tsa polyether le ho hanyetsa lik'hemik'hale ho li etsa hore li be ntle bakeng sa ho etsa lisebelisoa tsa bongaka le li-scaffold tsa boenjiniere ba lisele. Li ka mamelloa hantle ke lisele tsa batho ha li ntse li fana ka matla a hlokahalang a mechini le ho tšoarella. Liresine tsa polyether li boetse li sebelisoa ho hlahisa lijari tsa ho lokolla lithethefatsi, ho laola sekhahla sa ho lokolloa ha lithethefatsi ho ntlafatsa litlamorao tsa kalafo.
