I-Desmodur RE, eyaziwa nangokuthi i-CAS 2422-91-5, iyinhlanganisela eguquguqukayo futhi esetshenziswa kabanzi.Ngenxa yokusebenza kwayo okuhle kakhulu kanye nezinzuzo, iye yasetshenziswa kabanzi ezimbonini ezihlukahlukene.Kulesi sihloko, sihlola ukusetshenziswa kwe-Desmodur futhi sithola ukuthi kungani idume kangaka kubakhiqizi.
I-Desmodur RE ingeyomndeni wama-disocyanate anephunga elimnandi, izinhlanganisela ezisetshenziswa kabanzi ekukhiqizeni izimbotshana ze-polyurethane, izinto zokunamathisela nama-elastomers.Iwuketshezi oluphuzi olukhanyayo ukuya ku-amber oluhlanganisa ingxube yama-isomer anezakhiwo zamakhemikhali ezifanayo.Isithako esiyinhloko se-Desmodur RE i-toluene diisocyanate (TDI), esetshenziswa kakhulu ekukhiqizeni igwebu le-polyurethane.
Enye yezinto ezisetshenziswa kakhuluI-Desmodur REikhiqizwa nge-polyurethane coatings.Izembatho ze-polyurethane zinikeza isivikelo esihle kakhulu ekugqwaleni, esimweni sezulu kanye nokuhuzuka.Baziwa ngokuhlala kwabo okuphezulu nokusebenza okuhle kakhulu ezindaweni ezinokhahlo.I-Desmodur RE iyingxenye eyinhloko kulezi zakhiwo zokumboza, ezinikeza ubulukhuni obuningi, ukunamathela kanye nokumelana namakhemikhali.
Esinye isicelo esibalulekile se-Desmodur RE ukukhiqizwa kwezinamathelisi ze-polyurethane.Izinamathiselo ze-polyurethane zisetshenziswa kakhulu ezimbonini zezimoto, ezokwakha kanye nefenisha ngenxa yamandla azo ebhondi aphakeme nokuguquguquka.I-Desmodur RE ithuthukisa amandla esibopho sezinto ezinamathelayo ze-polyurethane, ezivumela ukuthi zibambelele kuma-substrates ahlukahlukene njengensimbi, ipulasitiki nokhuni.Lokhu kubenza balungele ukusetshenziswa kwe-lamination, ukubopha nokufaka uphawu.
I-Desmodur RE iphinde isetshenziswe ekukhiqizeni ama-polyurethane elastomers.Ama-polyurethane elastomers akhombisa izinto ezinhle kakhulu zemishini njengokunwebeka okuphezulu, ukumelana nokukhala kanye nokumelana nemihuzuko.Asetshenziswa ezimbonini ezifana nezicathulo, ezezimoto nezimboni.I-Desmodur RE idlala indima ebalulekile ekuhlanganiseni kwalawa ma-elastomer, iwanikeze amandla aqinile okuqinile kanye nezakhiwo zokwelula.
Ngaphezu kwalokho,I-Desmodur REyaziwa ngezakhiwo zayo ezelapha ngokushesha.Lokhu kusho ukuthi ingaxhumanisa ngokushesha nama-polyols ukuze yakhe inethiwekhi ye-polyurethane eqinile.Ukwelapha ngokushesha kuyinto efiselekayo kakhulu ezimbonini ezidinga izikhathi zokushintsha ngokushesha, njengezimboni zezimoto noma zokwakha.Ngaphezu kwalokho, i-Desmodur RE inokuhambisana okuhle nezinhlobonhlobo zama-polyols, okwenza abakhiqizi bakwazi ukuhlanganisa izakhiwo zemikhiqizo yabo nezimfuneko ezithile.
Sengiphetha, i-Desmodur RE (CAS 2422-91-5) iyinhlanganisela esetshenziswa kabanzi enezinhlelo zokusebenza ezibanzi ezimbonini ezinjengokumboza, okokunamathelisa kanye nama-elastomers.Izakhiwo zayo eziyingqayizivele, kuhlanganise nobulukhuni obuthuthukisiwe, ukunamathela kanye nokwelapha okusheshayo, kuyenza ibe yinto ethandwayo phakathi kwabakhiqizi.Ukuthi ihlinzeka ngokuvikela ukugqwala ngezingubo ze-polyurethane, ukuzuza izibopho eziqinile kuzinto ezinamathelayo, noma ukuthuthukisa izakhiwo zemishini zama-elastomers, i-Desmodur RE ibonise ukuthi iyingxenye ebalulekile ekukhiqizweni kwezinto ezisebenza kahle kakhulu.
