Chakudya Cha Mafakitale Diethyltoluenediamine DETDA Cas 68479-98-1
Diethyltoluenediamine, yomwe chidule chake ndi DETDA, ndi chinthu chofunikira kwambiri chachilengedwe chokhala ndi nambala ya CAS ya 68479-98-1. Diethyl Toluene Diamine ndi chowonjezera chamadzimadzi chotchedwa steric choletsa aromatic diamine chain extender komanso chothandizira kuchiritsa ma polyurethane elastomers ndi ma epoxy resins. Diethyltoluenediamine DETDA imagwiritsidwa ntchito popanga zinthu monga kuponyera, kuphimba, RIM ndi zomatira, ndi zina zotero. Diethyl Toluene Diamine imatha kukulitsa mphamvu ndi kukana kwa hydrolysis pazinthu, zomwe zimapangitsa kuti zikhale zotheka kupanga zinthu zazikulu komanso zovuta za polyurethane. Diethyltoluenediamine DETDA ingagwiritsidwenso ntchito ngati chothandizira kuchiritsa ma epoxy ndi ma alkyd resins, antioxidant ya mafuta a rabara, chothandizira utoto ndi mankhwala ophera tizilombo, ndi zina zotero.
Diethyltoluene diamine ingagwiritsidwe ntchito mu polyurethane, yomwe ingathandize kulimbitsa mphamvu ndi kukana kwa hydrolysis kwa zinthu, kupititsa patsogolo kwambiri kupanga zinthu, ndikupangitsa kuti zinthu za polyurethane zikhale zazikulu komanso zovuta kuzipanga.

Diethyltoluenediamine imagwiritsidwa ntchito makamaka ngati chotsukira mafuta chopaka utoto wosalowa madzi, chotsukira mafuta cha polyurethane ndi epoxy resin, komanso chotsukira mafuta chopangira mankhwala ophera tizilombo toyambitsa matenda. Kuphatikiza apo, DETDA ingagwiritsidwenso ntchito ngati mafuta opangira mafakitale.
※ Munda wa polyurethane
Chowonjezera unyolo: Diethyltoluenediamine DETDA ndi chowonjezera unyolo chogwira ntchito kwambiri cha ma polyurethane elastomers ndi ma polyurea elastomers, makamaka choyenera kupanga reaction injection molding (RIM) ndi spray polyurea elastomer (SPUA). Kuchuluka kwa reaction pakati pa Diethyl Toluene Diamine ndi polyurethane prepolymers ndi kwachangu, zomwe zingapangitse zinthuzo kukhala ndi ubwino monga mphamvu yoyamba, kukana hydrolysis, komanso kukana kutentha. Diethyltoluenediamine ingathandizenso kulimbitsa mphamvu za zinthuzo, zomwe zimapangitsa kuti zikhale zotheka kupanga zinthu zazikulu komanso zovuta za polyurethane.
Chothandizira kuchiritsa: Diethyltoluenediamine DETDA, monga chothandizira kuchiritsa cha diamine cha polyurethane elastomers ndi epoxy resins, imagwiritsidwa ntchito m'magawo monga kuponyera, zokutira, ndi zomatira.
※Mu gawo la epoxy resin
Diethyltoluenediamine ingagwiritsidwe ntchito ngati chothandizira kuchiritsa komanso ngati antioxidant ya epoxy resin, yomwe ingathandize kukonza magwiridwe antchito a epoxy resin, kuwonjezera kukana kutentha ndi kukana dzimbiri, ndi zina zotero.
※Magawo ena
Ethancure 100 ingagwiritsidwe ntchito ngati chothandizira popangira mankhwala ophera tizilombo ndi utoto, chothandizira polimbana ndi ma pulasitiki, rabara ndi mafuta, komanso chothandizira popangira zinthu zachilengedwe, ndi zina zotero.
