I-Desmodur Re, eyaziwa nangokuthi i-CAS 2422-91-5, iyindawo ehlukahlukene futhi esetshenziswa kabanzi. Ngenxa yokusebenza kwayo okuhle nezinzuzo ezinhle, kusetshenziswe kabanzi emikhakheni ehlukahlukene. Kulesi sihloko, sihlola ukusetshenziswa kweDesmodur futhi sithole ukuthi kungani ithandwa kakhulu ngabakhiqizi.
I-Desmodur Re re for umndeni we-aromatic diisocyanates, amakhompiyutha asetshenziswa kabanzi ekukhiqizweni kwezimbozo ze-polyurethane, anamathela kanye nama-lastomers. Kuphuzi okukhanyayo ku-amber ketshezi okubandakanya ingxube yama-isomers anezinhlaka ezifanayo zamakhemikhali. Isithako esiyinhloko seDesmodur Re yi-Tolune Diisocyanate (TDI), esetshenziswa kabanzi ekukhiqizweni kwe-polyurethane Foam.
Okunye kokusetshenziswa okuyinhloko kweDesmodur reisekwenziweni kwe-Polyurethane Coatings. I-Polyurethane Coatings ihlinzeka ngokuvikelwa okuhle kakhulu ekugqwaneni, isimo sezulu kanye ne-abrasion. Bayaziwa ngokuqina kwabo okuphezulu nokusebenza okuhle ezindaweni ezinokhahlo. I-Desmodur Re yingxenye esemqoka kulezi zinhlaka zenhlanganisela, zibanikeze ubunzima obukhulayo, ukunamathela kanye nokuphikiswa kwamakhemikhali.
Olunye ukusetshenziswa okubalulekile kwe-Desmodur Re ukukhiqizwa kwezithasiselo ze-polyurethane. Izikhangiso ze-polyurethane zisetshenziswa kabanzi kwizimboni zezimoto, zokwakha kanye nefenisha ngenxa yamandla abo amakhulu kanye nokuguquguquka okuhlukahlukene. I-Desmodur Re Khulisa amandla eBond of polyurethane anamathela, okubavumela ukuba banamathele ezindaweni ezahlukahlukene ezifana nensimbi, ipulasitiki nezinkuni. Lokhu kubenza balungele ukugcwala, ukubopha kanye nokubekwa uphawu.
I-Desmodur Re futhi isetshenziswa ekwenziweni kwama-polyurethane lastomers. Ama-polyurethane lastomers abonisa izakhiwo ezinhle kakhulu zemishini ezifana nokuqina okuphezulu, ukumelana nezinyembezi kanye nokumelana nokuphikiswa kwegciwane. Zisetshenziswa ezimbonini ezinjengezinyawo ezinjengezinyawo, ezenzakalweni zezimoto nezezimboni. I-Desmodur Re re re idlala indima ebalulekile ekuhlanganiseni kwalawa ma-lastomes, ibanikeze amandla amahle kakhulu kanye nezakhiwo ezibucayi.
Ngaphezu kwalokho,Desmodur reyaziwa ngezakhiwo zayo zokuvula ngokushesha. Lokhu kusho ukuthi kungasheshisa ngokushesha - ukuxhumana nama-polyols ukwakha inethiwekhi eqinile ye-polyurethane. Ukulapha okusheshayo kuyinto efiselekayo kakhulu ezimbonini ezidinga izikhathi eziguqukayo ezisheshayo, njengezimboni zezimoto noma zokwakha. Ngaphezu kwalokho, i-Desmodur Re ukuhambisana okuhle okunobubanzi be-polyols, okwenza abakhiqizi bakwazi ukuvumelanisa izakhiwo zemikhiqizo yabo kwizidingo ezithile.
Ekuphetheni, i-Desmodur Re (Cas 2422-91-5) iyindawo esetshenziswa kabanzi ngezinhlelo ezibanzi ezimbonini ezinjengezimbobo, ukunamathela kanye nama-lastomers. Izakhiwo zayo ezihlukile, kufaka phakathi ubunzima obuthuthukisiwe, ukunamathela nokwelashwa okusheshayo, kwenze kube yindlela ethandwa kakhulu phakathi kwabakhiqizi. Noma ngabe ukuhlinzeka ngokuvikelwa kokugqwala nge-polyurethane emboni, kufinyelela izibopho eziqinile ezinamathelayo, noma ukuthuthukisa izakhiwo zemishini zakwa-elastomers, i-desmodur re
