I-Diethyltoluenediamine (DETDA) CAS 68479-98-1
I-Diethyl-toluene-diamine (DETDA), inombolo ye-CAS 68479-98-1 iyi-ejenti yokwelapha uketshezi lwe-diamine enuka kamnandi, efana ne-Ethacure 100 kanye ne-DETDA 80, ye-polyurea kanye ne-polyurethane (PU).
Njengoba iyi-chain extender ephumelelayo yokusetshenziswa kwe-polyurethane, i-DETDA iyisisombululo esifanele ngezindleko zayo eziphansi kanye nezakhiwo ezinhle kakhulu, ikakhulukazi i-RIM (i-reaction injection molding) kanye ne-SPUA (Spray Polyurea Elastomer). I-DETDA ivumela ukwelashwa kwe-polyurethane/epoxy ngesikhathi esifushane kakhulu, ingenama-tack ngemizuzwana futhi ivala kahle indawo ukuze ivikele phansi, ama-facade, uphahla namabhuloho. Okuhle kunakho konke, i-polyurea yohlobo lwe-DETDA imboza futhi ivale izindawo eziqondile ngemizuzwana embalwa ngaphandle kokugoba.
I-DETDA iyi-chain extender evame kakhulu embonini ye-polyurethane, ine-viscosity ephansi, ingaphathwa kalula futhi inobungani nemvelo. Njengoba iyisimo soketshezi, i-DETDA ingacutshungulwa ekushiseni kwegumbi futhi ilashwe kahle. Ngaphezu kwalokho, ama-elastomer ohlobo lwe-DETDA anokuqina okuphezulu okufana nokwe-MOCA. Okwamanje, kunobuthi obuncane kanye nothuli esitshalweni sokukhiqiza uma kuqhathaniswa ne-MOCA.
Ngokufanayo nokusetshenziswa kwayo ku-polyurethane kanye ne-polyurea njengezinto zokupholisa, i-DETDA isetshenziswa njenge-hardener kanye ne-crosslinker yama-resin epoxy. Amaqembu ayo amabili e-amine asabela ngamaqembu amane e-epoxy, futhi akha ngisho nesikhungo sokuxhumanisa esinokushisa okuphezulu kanye ne-bisphenol A. Ngokulungisa umthamo, i-DETDA inganikeza ukusabela okusheshayo kanye nobubanzi bokuxhumanisa lapho ifuna.
Uma kuqhathaniswa ne-DMTDA, i-DimethylthioToluene Diamie, ayikho iphunga elibi lesibabule futhi imikhiqizo eqediwe yokwelapha ilukhuni uma inezakhiwo zomzimba ezingcono.
I-DETDA isetshenziswa kakhulu njenge-ejenti yokwelapha uhlelo lokufafaza i-polyurethane/polyuria ukuze kuvikelwe isikhathi eside zonke izindawo. Ngenxa yesakhiwo sayo sokwelapha ngokushesha, i-DETDA isetshenziswa kabanzi ekwakheni nasezintweni zokwakha. Iyisisombululo esifanele esidinga ukumbozwa/ukuvalwa okusheshayo, okusebenzayo nokuhlala isikhathi eside.
Kulabo ababandakanyeka ekufutheni izembozo ze-polyurea, ama-polyurethane, ama-composites nama-epoxy resins, kuzoba nzima ngawe ukuthola ezinye izinto ezizongena esikhundleni se-DETDA ezifanela izidingo zakho zokucubungula. Ijubane layo eliyingqayizivele lokuphola lenza kube ngenye yalezi zinto.
Ngaphezu kwalokho, i-DETDA isetshenziswa futhi njenge-ejenti yokwelapha/i-crosslinker ye-polyurethane ne-epoxy resin, i-antioxidant ye-epoxy resin, uwoyela wezimboni kanye nezinto zokugcoba. Ngaphezu kwalokho, i-Diethyl-toluene-diamine isetshenziswa njenge-medium in organic synthesis.
Ukupakisha: 20kg, 200kg/isigubhu sensimbi. noma i-IBC TANK.
Ukugcina kanye nokuthuthwa: Gwema ukuthintana namanzi. Gcina kude nokukhanya kwelanga.
