Cov Tshuaj DMDEE Ua Haujlwm Siab Rau Polyurethane Ua Npuas Ncauj

Cov Khoom Siv DMDEE Ua Haujlwm Siab Rau Polyurethane Ua Npuas Ncauj Duab Tshwj Xeeb

piav qhia luv luv:

Dimorpholinodiethyl Ether (DMDEE) yog ib qho tshuaj amine uas ua rau cov tshuaj urethane ua haujlwm sai dua, ua rau DMDEE tseem ceeb rau kev tsim cov ua npuas ncauj thiab yoog tau, nrog rau cov txheej txheem txheej thiab cov nplaum. DMDEE qhia txog kev xaiv zoo heev, txhawb cov txheej txheem gelation yam tsis muaj kev tsis haum ntau dhau, uas ua kom cov khoom zoo thiab kev ua tau zoo. Nrog rau kev yaj zoo hauv feem ntau cov kab ke polyurethane, DMDEE txhim kho kev sib txuas ua haujlwm thiab ua kom lub sijhawm kho luv dua, txhawb kev tsim khoom. DMDEE kuj qhia txog kev hloov pauv tsawg thiab tsw tsawg, ua raws li cov qauv kev nyab xeeb hauv kev lag luam thiab ua rau DMDEE yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm siab, kev siv polyurethane zoo rau ib puag ncig thoob ntiaj teb.

Dimorpholinodiethyl Ether (DMDEE, CAS 6425-39-4)yog ib qho tshuaj catalyst tertiary amine uas muaj kev ua tau zoo heev, nws qhov kev xaiv tshwj xeeb, kev hloov pauv tsawg, thiab kev sib raug zoo nrog polyurethane (PU) systems—tso nws ua ib qho khoom siv tseem ceeb rau kev tsim khoom lag luam uas muaj kev ua haujlwm siab. Tsis zoo li cov tshuaj catalysts amine generic, DMDEE xa cov kev ua kom nrawm ntawm cov tshuaj urethane cross-linking, txo cov tshuaj tiv thaiv sab thiab ua kom cov tshuaj kho zoo ib yam yam tsis muaj kev cuam tshuam rau cov qauv khoom, ua raws li cov qauv zoo thoob ntiaj teb thiab cov qauv ib puag ncig.

Cov ntawv thov ntawm DMDEE npog ntau yam kev lag luam muaj nqis siab: nws yog qhov catalyst xaiv rau kev tsim cov ua npuas ncauj PU uas ruaj khov thiab yoog tau siv rau hauv kev tsim kho rwb thaiv tsev thiab lub rooj zaum hauv tsheb, qhov twg nws ua rau cov ua npuas ncauj ntom ntom thiab lub zog kho tshuab; nws ua haujlwm ua lub tshuab ua kom zoo rau PU coatings, adhesives, thiab sealants, luv luv cov voj voog ntau lawm thaum txhim kho kev ruaj khov thiab tshuaj lom neeg tsis kam; ntxiv rau, DMDEE ua haujlwm ua cov khoom pabcuam tseem ceeb hauv cov PU elastomers tshwj xeeb rau kev tsim cov ntaub thiab khau.

Peb cov khoom lag luam DMDEE muaj cov qib tshwj xeeb (qib kev lag luam, qib siab huv, thiab qib tsw qab tsawg) kom phim cov kev xav tau ntawm ntau yam kev siv, nrog rau cov txheej txheem tswj xyuas zoo nruj uas lav cov qib tsis huv hauv qab 0.05% thiab cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg kom ruaj khov. Peb muab cov kev daws teeb meem yooj ywm, xws li cov pob khoom me me mus rau cov khoom xa tuaj ntawm IBC tote thiab lub thawv tank, nrog rau cov ntaub ntawv ua raws li kev cai (suav nrog ntau hom lus MSDS, daim ntawv pov thawj xa khoom UN, thiab cov ntaub ntawv sau npe REACH).
