Kugwiritsa ntchito kwa PACM
EPOXY RESIN CURING AGENT PACM ingagwiritsidwe ntchito pokonza mitundu yosiyanasiyana ya zokutira ndi zomatira za polyurethane zosawononga chilengedwe zomwe zimaonekera bwino komanso zimakana chikasu. Utomoni wa epoxy womwe umachiritsidwa ndi EPOXY RESIN CURING AGENT PACM uli ndi kukana kutentha kwabwino kwambiri kwa Chemicalbook, kukana kwa dielectric, kukana zosungunulira, kukana makina, komanso kukana kuwala kwabwino kwambiri, kukana nyengo, ndipo ungagwiritsidwe ntchito pazinthu zonyowa, zipangizo zowonera, zokutira, mapulasitiki aukadaulo, zomatira ndi zina.
- 4,4'-Methylenebis (cyclohexylamine) ndi mankhwala oletsa kutentha kwambiri komanso oletsa kutentha kwambiri.
- 4,4'-Diaminodicyclohexyl methane iyenera kugwiritsidwa ntchito ngati zinthu zosakaniza zachilengedwe komanso zinthu zochiritsa za epoxy.
- 4,4'-Diaminodicyclohexylmethane imagwiritsidwa ntchito ngati zinthu zochiritsira za epoxy. Ndi chinthu chogwiritsidwa ntchito popanga zikopa, zinthu za rabara, mapulasitiki, utoto, ndi ma polima omwe amakhudzidwa ndi zithunzi. Chimagwiritsidwa ntchito popanga ma diisocyanates ndi ma polyamides. Chimagwiritsidwanso ntchito ngati chowonjezera cha mafuta komanso choletsa dzimbiri.
Kukonzekera: Sakanizani ufa wa titanium dioxide 1g mu 40ml ya madzi ndi methanol (madzi kufika pa chiŵerengero cha voliyumu ya methanol ya 9: 1), sakanizani bwino mutasakaniza mofanana, onjezerani 60 μmol/ml RUCL3 · XH2O yankho lamadzi lakuda lofiirira kuti muwongolere kuchuluka kwa titanium dioxide mu titanium dioxide. Katunduyo ndi 5WT%. Pambuyo pa maola atatu otseka chisindikizo cha kutentha kwa chipinda ndikusakaniza kwa maola atatu, onjezerani yankho la 1m sodium hydroxide mpaka PH10.5 ipitirire kutseka ndikusakaniza kwa maola 20. Pambuyo pa centrifugation ndi madzi ndi ethanol osakaniza atsukidwa ndi madzi ndi ethanol kwa nthawi 3-5, 60 ° C. catalyst. Ma catalyst atsopano okonzedwa amayikidwa mu reactor, voliyumu inayake ya solvents imawonjezedwa, ndipo kuchuluka koyenera kwa 4,4'- awiri Chemicalbook amin aminomyl methane (MDA) kumawonjezedwa. Pambuyo pa nthawi 10, reactor yotsekedwayo imatsukidwa ndi ketulo ya hydrogen reaction mpaka 150 ° C kuti iyambe reaction. Chiŵerengero cha Moore cha hydrogen ndi MDA sichinali chochepera 80, ndipo kuthamanga kwa hydrogen kunali 1 mpaka 5MPa, ndipo zotsatira zake ndi kuchuluka kwa kusintha kwake zinatengedwa nthawi yeniyeni. Mzere wa benzene mu MDA ukhoza kukhala hydrogen mwachangu kuti upange mphete imodzi ya benzene hydrogenation (+6H) ndi hydrogenation ya bisopyzhenbenzhenyl hydrogenation. Ndikoyenera kunena kuti 4,4'-dihydrophill methal methane ndi mankhwala osaphika a nayiloni yapadera.
Kufotokozera kwa PACM
