Diethyltoluenediamine (DETDA) CAS 68479-98-1
Diethyl-toluene-diamine (DETDA), CAS nomero 68479-98-1 ni aromatike ya diamine y'amazi ahumura neza, isa na Ethacure 100 na DETDA 80, kuri polyurea na polyurethane (PU).
Kubera ko DETDA ari yo ikora neza mu gukoresha polyurethane, ni igisubizo cyiza cyane kuko ihendutse kandi ifite imiterere myiza, cyane cyane kuri RIM (reaction injection molding) na SPUA (Spray Polyurea Elastomer). DETDA ituma polyurethane/epoxy ikira mu gihe gito cyane, idafata mu masegonda menshi kandi igafunga neza ubuso kugira ngo irinde hasi, imbere, ibisenge n'ibiraro. Ikiruta byose, polyurea yo mu bwoko bwa DETDA itwikira kandi igafunga ubuso buhagaze mu masegonda make idatemba.
DETDA ni yo mashini ikoreshwa cyane mu nganda za polyurethane, ifite ubushyuhe buke, ishobora gutunganywa byoroshye kandi ikaba irinda ibidukikije. Kubera ko ari amazi, DETDA ishobora gutunganywa ku bushyuhe bw'icyumba kandi igakira neza. Byongeye kandi, elastomer zo mu bwoko bwa DETDA zifite ubushobozi bwo kwihanganira ibintu nk'ubwo mu bwoko bwa MOCA. Hagati aho, uburozi n'umukungugu bike mu ruganda rukora ugereranije na MOCA.
Kimwe n'uko ikoreshwa muri polyurethane na polyurea nk'ibikoresho bivura, DETDA ikoreshwa nk'icyuma gikomeza gukurura no guhuza ibyuma bya epoxy resins. Amatsinda yayo abiri ya amine agira ingaruka ku matsinda ane ya epoxy, ndetse agakora ihuriro ry'ubushyuhe bwinshi hamwe na bisphenol A. Mu guhindura ingano, DETDA ishobora gutanga igisubizo cyihuse no guhuza ibyuma iyo bikenewe.
Ugereranyije na DMTDA, DimethylthioToluene Diamie, nta mpumuro mbi ya sulfure ihari kandi ibikoresho birangira neza birakomera iyo bifite imiterere myiza.
DETDA ikoreshwa cyane cyane nk'umuti uvura indwara za polyurethane/polyuria kugira ngo uburinzi bw'ubuso bwose burambe. Kubera ubushobozi bwayo bwo gukira vuba, DETDA ikoreshwa cyane mu bwubatsi no mu bikoresho by'ubwubatsi. Ni igisubizo cyiza gisaba gutwikira/gufunga vuba, neza kandi birambye.
Ku bakora ibijyanye no gutera irangi rya polyurea, polyurethane, composites na epoxy resins, bizakugora kubona DETDA isimbura ijyanye n'ibyo ukeneye mu gutunganya. Umuvuduko wayo wihariye wo kuyitunganya utuma iba imwe muri zo.
Byongeye kandi, DETDA ikoreshwa kandi nk'ikintu gikingira/gihuza polyurethane na epoxy resin, antioxydant ya epoxy resin, amavuta yo mu nganda n'amavuta yo kwisiga. Byongeye kandi, Diethyl-toluene-diamine ikoreshwa nk'igice cyo hagati mu gukora organic synthesis.
Gupakira: 20kg, 200kg/ingoma y'icyuma cyangwa IBC TANK.
Kubika no gutwara: Irinde ko byagera mu mazi. Bika kure y'izuba.
Igihe cyo kuruhuka: amezi 12
