Diethyltoluenediamine (DETDA) CAS 68479-98-1
Diethyl-toluene-diamine (DETDA), lambarka CAS 68479-98-1 waa wakiilka dareeraha diamine udgoon, kaas oo la mid ah Ethacure 100 iyo DETDA 80, ee polyurea iyo polyurethane (PU).
Ahaanshaha silsilad wax ku ool ah oo loogu talagalay codsiyada polyurethane, DETDA waa xal ku habboon oo leh qiimaheeda hoose iyo sifooyinkeeda ugu wanaagsan, gaar ahaan RIM (qaabaynta duritaanka falcelinta) iyo SPUA (Spray Polyurea Elastomer). DETDA waxay awood u siinaysaa dawooyinka polyurethane/epoxy waqti aad u yar gudaheed, bilaa-xakameyn ilbiriqsiyo gudaheed oo si fiican u xir dusha si aad u ilaaliso sagxadaha, wejiyada, saqafyada iyo buundooyinka. Waxa ugu wanagsan, nooca DETDA ee polyurea waxa ay dabooshaa oo ku xidhaa sagxadaha toosan dhawr ilbiriqsi gudaheed iyada oo aan hoos u dhicin.
DETDA waa silsiladaha ugu caansan warshadaha polyurethane, waxay leedahay viscosity hoose, si fudud ayaa loo maarayn karaa oo saaxiibtinimo ka badan. Maadaama ay tahay qaabka dareeraha, DETDA waxaa lagu farsamayn karaa heerkulka qolka oo si fiican loo daaweeyaa. Intaa waxaa dheer, elastomer-ka nooca DETDA waxay leeyihiin adkeysi firfircoon oo la mid ah kuwa nooca MOCA. Dhanka kale, waxaa ka yar sunta iyo boodhka warshadda wax soo saarka marka la barbar dhigo MOCA.
Si la mid ah u isticmaalkeeda polyurethane iyo poliurea sida dawooyinka, DETDA waxa loo isticmaalaa sidii qallajiye iyo iskutallaabta resins epoxy. Labadeeda kooxood ee aminiga ah waxay la falgalaan afar kooxood oo epoxy ah, oo xitaa waxay sameeyaan xarun iskutallaabta heerkulka sare leh oo ay la socdaan bisphenol A. Iyadoo la hagaajinayo qiyaasta, DETDA waxay ku siin kartaa falcelin degdeg ah iyo kala duwanaansho isku dhafan marka la dalbanayo.
Marka la barbar dhigo DMTDA, DimethylthioToluene Diamie, ma jirto ur baaruud ah oo aan fiicnayn iyo daawaynta alaabooyinka la dhammeeyey way adag tahay iyaga oo leh sifooyin jireed oo wanaagsan.
DETDA waxaa inta badan loo isticmaalaa sidii wakiilka daawaynta ee nidaamka buufinta poliurethane/poyuria si ay u ilaaliso waarta oo dhan. Iyada oo leh hantideeda degdega ah, DETDA waxaa si weyn loogu isticmaalaa dhismaha iyo qalabka dhismaha. Waa xal ku habboon oo dalbanaya dahaar/xidhid degdeg ah, hufan oo waara.
Kuwa ku hawlan buufinta dahaarka poliurea, polyurethanes, composites iyo resins epoxy, way kugu adkaan doontaa inaad hesho beddelka DETDA ee ku habboon baahiyahaaga habaynta. Xawaaraha daaweynta ee gaarka ah ayaa ka dhigaya mid ka mid ah nooca.
Intaa waxa dheer, DETDA waxa kale oo loo istcimaalaa daawaynta/iskutallaabaha polyurethane iyo resin epoxy, antioxidant of resin epoxy, saliid warshadaha iyo saliidaha. Intaa waxaa dheer, Diethyl-toluene-diamine waxaa lagu dabaqaa sida dhexdhexaadka ah ee isku-dhafka dabiiciga ah.
