Diethyltoluenediamine (DETDA) CAS 68479-98-1
Diethyl-toluene-diamine (DETDA), CAS tus lej 68479-98-1 yog ib qho tshuaj tua kab mob aromatic diamine, uas zoo ib yam li Ethacure 100 thiab DETDA 80, rau polyurea thiab polyurethane (PU).
Ua ib qho saw hlau txuas zoo rau cov ntawv thov polyurethane, DETDA yog ib qho kev daws teeb meem zoo tshaj plaws nrog nws cov nqi qis thiab cov khoom zoo heev, tshwj xeeb tshaj yog rau RIM (kev txhaj tshuaj molding) thiab SPUA (Spray Polyurea Elastomer). DETDA ua rau polyurethane / epoxy kho tau sai heev, tsis muaj tack hauv vib nas this thiab kaw qhov chaw zoo meej los tiv thaiv cov plag tsev, facades, ru tsev thiab choj. Qhov zoo tshaj plaws, DETDA-hom polyurea npog thiab kaw cov chaw ntsug hauv ob peb vib nas this yam tsis muaj sagging.
DETDA yog cov saw hlau txuas feem ntau hauv kev lag luam polyurethane, nws muaj viscosity qis, tuaj yeem tuav tau yooj yim thiab zoo rau ib puag ncig. Vim yog cov kua, DETDA tuaj yeem ua tiav ntawm chav tsev kub thiab kho tau zoo. Ntxiv mus, DETDA-hom elastomers muaj kev ua haujlwm siab zoo ib yam li MOCA-hom. Lub caij no, muaj tsawg dua tshuaj lom thiab hmoov av hauv cov nroj tsuag ntau lawm piv rau MOCA.
Ib yam li nws siv rau hauv polyurethane thiab polyurea ua cov neeg sawv cev curing, DETDA siv ua tus hardener thiab crosslinker rau epoxy resins. Nws ob pawg amine react nrog plaub pawg epoxy, thiab txawm tsim ib qho chaw kub siab crosslinking nrog bisphenol A. Los ntawm kev kho cov tshuaj, DETDA tuaj yeem muab cov tshuaj tiv thaiv sai thiab cross-linking ntau thaum xav tau.
Piv nrog DMTDA, DimethylthioToluene Diamie, tsis muaj ntxhiab tsw tsis zoo thiab cov khoom kho tiav lawm nyuaj dua nrog cov khoom zoo dua.
DETDA feem ntau yog siv los ua tus neeg sawv cev rau polyurethane / polyuria txau system rau kev tiv thaiv ntev ntawm txhua qhov chaw. Nrog nws cov khoom kho sai, DETDA yog siv dav hauv kev tsim kho thiab cov ntaub ntawv hauv tsev. Nws yog ib qho kev daws teeb meem zoo tshaj plaws uas xav tau kev txheej txheem / sealing sai, ua haujlwm tau zoo thiab kav ntev.
Rau cov neeg uas siv tshuaj tsuag polyurea coatings, polyurethanes, composites thiab epoxy resins, nws yuav nyuaj rau koj nrhiav DETDA hloov uas haum rau koj cov kev xav tau ua. Nws qhov ceev kho tshwj xeeb ua rau nws yog ib qho ntawm hom.
Tsis tas li ntawd xwb, DETDA kuj siv ua tus neeg sawv cev curing / crosslinker ntawm polyurethane thiab epoxy resin, antioxidant ntawm epoxy resin, roj industrial thiab lubricants. Tsis tas li ntawd, Diethyl-toluene-diamine yog siv ua intermediate hauv organic synthesis.
Ntim: 20kg, 200kg / hlau nruas. lossis IBC TANK.
Kev Khaws Cia thiab Kev Thauj Mus Los: Tsis txhob cia dej kov. Khaws kom deb ntawm tshav ntuj.
