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 aqine kakhulu aqinile 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.
