Desmodur RE, eo hape e tsejoang ka hore ke CAS 2422-91-5, e sebetsa ka mefuta e mengata ebile e sebelisoa haholo.Ka lebaka la ts'ebetso ea eona e ntle le melemo, e 'nile ea sebelisoa haholo liindastering tse sa tšoaneng.Sengoliloeng sena, re hlahloba ts'ebeliso ea Desmodur mme re fumane hore na hobaneng e tumme hakana ho bahlahisi.
Desmodur RE ke ea lelapa la li-disocyanate tse nkhang hamonate, metsoako e sebelisoang haholo ha ho etsoa liaparo tsa polyurethane, likhomaretsi le li-elastomers.Ke mokelikeli o mosehla o bobebe ho isa ho amber o nang le motsoako oa li-isomers tse nang le likarolo tse tšoanang tsa lik'hemik'hale.Motsoako o ka sehloohong oa Desmodur RE ke toluene diisocyanate (TDI), e sebelisoang haholo ho hlahisa foam ea polyurethane.
E 'ngoe ea lisebelisoa tse ka sehloohong tsaDesmodur REe entsoe ka masela a polyurethane.Liaparo tsa polyurethane li fana ka tšireletso e babatsehang khahlanong le kutu, boemo ba leholimo le abrasion.Li tsebahala ka ho tšoarella ha tsona holimo le ts'ebetso e ntle haholo libakeng tse thata.Desmodur RE ke karolo ea bohlokoa mefuteng ena ea ho roala, e ba fang boima bo eketsehileng, ho khomarela le ho hanyetsa lik'hemik'hale.
Tšebeliso e 'ngoe ea bohlokoa ea Desmodur RE ke tlhahiso ea li-adhesives tsa polyurethane.Likhomaretsi tsa polyurethane li sebelisoa haholo indastering ea likoloi, ea kaho le ea thepa ea ka tlung ka lebaka la matla a tsona a holimo a tlamo le ho feto-fetoha ha maemo.Desmodur RE e ntlafatsa matla a tlamahano ea likhomaretsi tsa polyurethane, e li lumellang hore li khomarele likarolo tse fapaneng tse kang tšepe, polasetiki le lehong.Sena se etsa hore e be tse loketseng bakeng sa lisebelisoa tsa lamination, bonding le ho tiisa.
Desmodur RE e boetse e sebelisoa ha ho etsoa li-elastomer tsa polyurethane.Li-elastomers tsa polyurethane li bonts'a thepa e ntle ea mochini joalo ka elasticity e phahameng, ho hanyetsa meokho le ho hanyetsa abrasion.Li sebelisoa liindastering tse kang tsa lieta, tsa likoloi le tsa indasteri.Desmodur RE e bapala karolo ea bohlokoa ho hlahisoeng ha li-elastomer tsena, ho li fa matla a matle haholo le ho holisa.
Ho feta moo,Desmodur REe tsebahala ka ho phekola ka potlako.Sena se bolela hore e ka potlakela ho hokahanya le polyols ho theha marang-rang a matla a polyurethane.Ho phekola ka potlako ho lakatseha haholo liindastering tse hlokang linako tse potlakileng tsa phetoho, joalo ka liindasteri tsa likoloi kapa tsa kaho.Ho feta moo, Desmodur RE e lumellana hantle le mefuta e mengata ea polyols, e nolofalletsang baetsi ba lihlahisoa ho fetola thepa ea lihlahisoa tsa bona ho latela litlhoko tse khethehileng.
Qetellong, Desmodur RE (CAS 2422-91-5) ke motsoako o sebelisoang haholo o nang le lisebelisoa tse pharaletseng liindastering tse kang liphahlo, li-adhesives le elastomers.Lintho tsa eona tse ikhethang, tse kenyelletsang ho thatafala ho matlafalitsoeng, ho khomarela le ho phekola ka potlako, li etsa hore e be khetho e ratoang har'a bahlahisi.Hore na e fana ka ts'ireletso ea kutu ka likhoele tsa polyurethane, ho fihlela litlamo tse matla ho likhomaretsi, kapa ho ntlafatsa thepa ea mochini oa li-elastomers, Desmodur RE e ipakile e le karolo ea bohlokoa tlhahisong ea lisebelisoa tse sebetsang hantle.
