Diethyltoluenediamine (DETDA) CAS 68479-98-1
Diethyl-toluene-diamine (DETDA), lambar CAS 68479-98-1 wani maganin warkar da ruwa ne mai ƙanshi na diamine, wanda yayi kama da Ethacure 100 da DETDA 80, don polyurea da polyurethane (PU).
Kasancewar na'urar tsawaita sarka mai inganci don aikace-aikacen polyurethane, DETDA mafita ce mai kyau tare da ƙarancin farashi da kyawawan halaye, musamman ga RIM (molding na allurar amsawa) da SPUA (SPRAY Polyurea Elastomer). DETDA tana ba da damar maganin polyurethane/epoxy cikin ɗan gajeren lokaci, ba tare da mannewa ba cikin daƙiƙa kuma ta rufe saman daidai don kare benaye, fuskoki, rufin gida da gadoji. Mafi kyawun duka, polyurea na DETDA yana rufewa da rufe saman tsaye cikin daƙiƙa kaɗan ba tare da yin lanƙwasa ba.
DETDA ita ce mafi yawan na'urar tsawaita sarkar a masana'antar polyurethane, tana da ƙarancin danko, ana iya sarrafa ta cikin sauƙi kuma ta fi dacewa da muhalli. Kasancewar sifar ruwa, ana iya sarrafa DETDA a zafin ɗaki kuma a warke sosai. Bugu da ƙari, elastomers na nau'in DETDA suna da juriya mai ƙarfi kamar na nau'in MOCA. A halin yanzu, akwai ƙarancin guba da ƙura a masana'antar samarwa idan aka kwatanta da MOCA.
Kamar yadda ake amfani da shi a polyurethane da polyurea a matsayin maganin warkarwa, ana amfani da DETDA a matsayin mai taurarewa da kuma mai haɗa haɗin gwiwa don resin epoxy. Rukunin amine guda biyu suna amsawa da ƙungiyoyin epoxy guda huɗu, har ma suna samar da cibiyar haɗin gwiwa mai zafi tare da bisphenol A. Ta hanyar daidaita adadin, DETDA na iya samar da saurin amsawa da kewayon haɗin gwiwa lokacin da ake buƙata.
Idan aka kwatanta da DMTDA, DimethylthioToluene Diamie, babu wani wari mai daɗi na sulfur kuma samfuran da aka gama suna da wahala tare da ingantattun halaye na zahiri.
Ana amfani da DETDA sosai a matsayin maganin warkarwa don tsarin fesawa na polyurethane/polyuria don kare dukkan saman da ke cikinsa na dogon lokaci. Tare da ikon warkarwa cikin sauri, ana amfani da DETDA sosai a cikin gini da kayan gini. Mafita ce mai kyau wacce ke buƙatar shafa/hatimi cikin sauri, inganci da ɗorewa.
Ga waɗanda ke fesa fenti mai rufi na polyurea, polyurethanes, composite da epoxy resins, zai yi muku wahala ku sami madadin DETDA waɗanda suka dace da buƙatunku na sarrafawa. Saurin warkarwa na musamman da yake bayarwa ya sa ya zama ɗaya daga cikin irinsa.
Bugu da ƙari, ana amfani da DETDA a matsayin wakili mai warkarwa/haɗin gwiwa na polyurethane da epoxy resin, antioxidant na epoxy resin, mai na masana'antu da man shafawa. Bugu da ƙari, ana amfani da Diethyl-toluene-diamine a matsayin matsakaici a cikin haɗakar kwayoyin halitta.
Marufi: 20kg, 200kg/ganga na ƙarfe. ko kuma TANK na IBC.
