Diethyltoluenediamine (DETDA) CAS 68479-98-1
Diethyl-toluene-diamine (DETDA), lambarka CAS 68479-98-1 waa wakiil daawayn dareere diamine ah oo aromatic ah, kaas oo la mid ah Ethacure 100 iyo DETDA 80, oo loogu talagalay polyurea iyo polyurethane (PU).
Iyada oo ah qalab wax ku ool ah oo loogu talagalay codsiyada polyurethane, DETDA waa xal ku habboon oo leh qiimo jaban iyo sifooyin aad u fiican, gaar ahaan RIM (qaabaynta duritaanka falcelinta) iyo SPUA (Spray Polyurea Elastomer). DETDA waxay awood u siineysaa in polyurethane/epoxy ay bogsato waqti aad u gaaban, iyada oo aan lahayn wax lagu dhejiyo ilbiriqsiyo gudahood waxayna si fiican u xirtaa dusha sare si ay u ilaaliso dabaqyada, wajiyada, saqafyada iyo buundooyinka. Waxa ugu fiican, polyurea-ga nooca DETDA wuxuu daboolaa oo xiraa dusha sare ee toosan dhowr ilbiriqsi gudahood iyada oo aan la qalloocin.
DETDA waa qalabka ugu badan ee fidiya silsiladda warshadaha polyurethane, waxay leedahay daxal hoose, si fudud ayaa loo maarayn karaa oo deegaanka u fiican. Maadaama ay tahay qaabka dareeraha ah, DETDA waxaa lagu farsameyn karaa heerkulka qolka waxaana si fiican loo daaweyn karaa. Intaa waxaa dheer, elastomer-ka nooca DETDA waxay leeyihiin adkeysi firfircoon oo sarreeya sida kuwa nooca MOCA. Dhanka kale, waxaa jira sun iyo boodh yar oo ku jira warshadda wax soo saarka marka la barbar dhigo MOCA.
Sida isticmaalka polyurethane iyo polyurea oo kale sida wakiilada daaweynta, DETDA waxaa loo isticmaalaa sidii adkeye iyo isku xidhe resins epoxy ah. Labadeeda kooxood ee amine waxay la falgalaan afar kooxood oo epoxy ah, xitaa waxay sameeyaan xarun isku xidha heerkul sare oo leh bisphenol A. Iyadoo la hagaajinayo qiyaasta, DETDA waxay bixin kartaa falcelin degdeg ah iyo kala duwanaansho isku xidha marka loo baahdo.
Marka la barbardhigo DMTDA, DimethylthioToluene Diamie, ma jiro ur xun oo sulfur ah, badeecadaha la dhammeeyayna way adag yihiin iyagoo leh sifooyin jireed oo wanaagsan.
DETDA waxaa si weyn loogu isticmaalaa sidii wakiilka daaweynta ee nidaamka buufinta polyurethane/polyuria si loo ilaaliyo dhammaan dusha sare. Iyada oo leh qaabkeeda bogsashada degdegga ah, DETDA si weyn ayaa loogu isticmaalaa dhismaha iyo agabka dhismaha. Waa xal ku habboon oo u baahan dahaadh/shaabadayn degdeg ah, hufan oo waara.
Kuwa ku hawlan buufinta dahaarka polyurea, polyurethanes, isku-dhafka iyo resins epoxy, way kugu adkaan doontaa inaad hesho beddelayaasha DETDA ee ku habboon baahiyahaaga farsamaynta. Xawaaraha bogsashada ee gaarka ah ayaa ka dhigaya mid ka mid ah noocyadaas.
Intaa waxaa dheer, DETDA waxaa sidoo kale loo isticmaalaa sidii wakiil bogsiin/isgoys ah oo ka kooban polyurethane iyo epoxy resin, antioxidant-ka resin epoxy, saliidda warshadaha iyo saliidaha. Intaa waxaa dheer, Diethyl-toluene-diamine waxaa loo isticmaalaa sidii dhexdhexaad ah marka la samaynayo isku-darka dabiiciga ah.
